ELI LILLY AND COMPANY,

Petitioner

V. .

DOUGLAS M. COSTLE, ADMINISTRATOR,

ENVIRONMENTAL PROTECTION AGENCY

PETITION FOR A WRIT OF CERTIORARI TO THE

UNITED STATES COURT OF APPEALS FOR

THE FIRST CIRCUIT

Eli Lilly and Company petitions for a writ of cer-

tiorari to review the judgment of the United States

Court of Appeals for the First Circuit in this case.

OPINIONS BELOW

The opinion of the Court of Appeals (App. A, infra)

is reported in 598 F.2d 637. The decision of the Admin-

istrator of the Environmental Protection Agency is set

forth in regulations published at 43 Fed. Reg. 17775

(App. C, infra).

JURISDICTION

The judgment of the Court of Appeals (App. B, infra)

was entered on May 7, 1979. A timely petition for re-

2

hearing was denied on June 25, 1979. The jurisdiction

of this Court is invoked under 28 U.S.C. § 1254(1).

QUESTIONS PRESENTED

1. Whether under Section 4 of the Administrative

Procedure Act EPA was required to provide notice and

an opportunity for public comment before promulgating

final regulations which differed substantially from the

“interim final” regulations, especially where the Agency

had generated a new and more extensive base of data

not previously disclosed for public comment?

2. Assuming that EPA was not required to give notice

and provide opportunity for public comment, whether the

court in carrying out its review of the regulations should

defer to those determinations by the Agency which were

based on new data?

8. Again assuming that EPA was not required to give

notice and provide opportunity for public comment,

whether the reviewing court should conduct its own de

novo review of new data and information, and impute

certain determinations to the Agency, where the Agency’s

determinations are either nonexistence or inadequate to

deal with the issues in dispute?

STATUTE INVOLVED

Sections 4(b) (3) and (c) of the Administrative Pro-

cedure Act, 5 U.S.C. § 553(b) (3), (c), provide in perti-

nent part:

§ 553. Rule making

(b) General notice of proposed rule making shall

be published in the Federal Register ... . The notice

shall include—

3

(3) either the terms or substance of the proposed

i or a description of the subjects and issues in-

volved.

* « * *

(c) After notice required by this section, the

agency shall give interested persons an opportunity

to participate in the rule making through submis-

sion of written data, views, or arguments....

STATEMENT

Section 301(b) of the Federal Water Pollution Control

Act, as amended, 38 U.S.C. §1311(b), authorizes the

Environmental Protection Agency (“EPA” or “Agency”)

to issue regulations establishing effluent limitations for

classes and categories of industrial point sources. Sec-

tion 304(b), 33 U.S.C. § 1314(b), requires EPA to es-

tablish guidelines for the purpose of adopting such efflu-

ent limitation regulations. See E. I. du Pont de Nemours

& Co. v. Train, 430 U.S. 112 (1977).

On November 1, 1976, EPA promulgated “interim

final regulations” for the Pesticide Chemicals Manufac-

turing Point Source Category. 41 Fed. Reg. 48087. The

interim final regulations established effluent limitations

for existing sources implementing the first-stage require-

ment of Section 301(b) for the application of best prac-

ticable control technology currently available by July 1,

1977.

1EPA did not publish the regulations in proposed form. Citing

an order of the United States District Court for the District of

Columbia, EPA determined that the publication of proposed regu-

lations was not practicable and, therefore, promulgated immediately

effective “interim final regulations”. 41 Fed. Reg. at 48088.

The Act also authorizes EPA to establish effluent limitations

implementing the second-stage requirement of the Act, best avail-

able technology economically achievable. See E. I. du Pont de

Nemours & Co. V. Train, 430 U.S. 112, 121 (1977). EPA decided to

propose those regulations separately and at a later date. 41 Fed.

Reg. at 48091.

4

Petitions for review of the interim final regulations

were filed in the United States Court of Appeals for the

First Circuit by BASF Wyandotte Corporation and five

other companies on January 24, 1977. Subsequently filed

petitions for review were transferred to that court. Eli

Lilly did not file a petition for review of the interim

final regulations.

EPA solicited comments on the interim final regula-

tions. 41 Fed. Reg. at 48088. Comments on the interim

final regulations were filed by a number of persons, in-

cluding various manufacturers of pesticides. App. C,

infra, 82a. Eli Lilly did not comment on the interim

final regulations.

On April 25, 1978, EPA promulgated final regula-

tions for the Pesticide Chemicals Manufacturing Point

Source Category. 43 Fed. Reg. 17775.? On July 18, 1978,

Eli Lilly filed a petition for review of the final regula-

tions in the United States Court of Appeals for the

Seventh Circuit. The petition was thereafter transferred

to the United States Court of Appeals for the First

Circuit.

Both the interim final and the final regulations estab-

lished effluent limitations on the discharge of pesticide

chemicals, five-day biochemical oxygen demand (“BOD,”),

and chemical oxygen demand (“COD”). The effluent

limitations are expressed in terms of pounds of pollutants

discharged for each thousand pounds of pesticide chemi-

cal manufactured (“Ibs./1000 lbs.”) and its metric

equivalent (“kg./kkg.”). Both a daily maximum dis-

charge level and a maximum average discharge level over

a 30-day period are specified.

2 The final regulations were amended subsequently to limit the ap-

plication of the effluent limitations for the discharge of pesticide

chemicals to 49 specified pesticides. 43 Fed. Reg. 44845 ( -pt. 29,

1978).

The interim final regulations established effluent limi-

tations for three separate subcategories of facilities pro-

ducing organic pesticides: halogenated organic pesticides

(Subcategory A), organo-phosphorous pesticides (Sub-

category B), and organo-nitrogen pesticides (Subcate-

gory C). Significantly different effluent limitations were

prescribed for each subcategory,* and different data were

used in deriving the effluent limitations for each subcate-

gory. 41 Fed. Reg. at 48089-90. Eli Lilly manufactures

an organo-nitrogen pesticide, trifluralin, at its Lafayette,

Indiana plant.‘

The final regulations collapsed the separate effluent

limitations for the three categories into a single subca-

tegory of organic pesticides and established a uniform

set of effluent limitations for all organic pesticides. 40

C.F.R. § 455.22, App. C, infra, 105a.

The final effluent limitations for the collapsed subcate-

gory of organic pesticides are substantially more strin-

gent pel the effluent limitations established by the in-

terim final regulations for organo-nitrogen pesticides, in-

cluding trifluralin: nosis

6

The data used in deriving the final effluent limita-

tions for the collapsed subcategory were different from

those used to derive the interim final effluent limitations

for the organo-nitrogen pesticide subcategory.

In the preamble and appendix to the final regulations,

EPA described the “major changes” in the regulations

and the “expanded data base” upon which those major

changes were premised. App. C, infra, 63a-67a, 87a-89a.

One of the major changes described was the collapsing

of the organic pesticide subcategories. EPA stated that

the revisions to the regulations, including the elimination

of subcategories, were based on the expanded data base

and the Agency’s reexamination of the data. App. C,

infra, 64a. EPA further stated that the decision not to

differentiate among different organic pesticides and to

eliminate the interim subcategories was based on new

data indicating that the “quantities of pollutants in the

effluents of those plants with the properly operated model

technologies installed were similar regardless of the or-

ganic pesticide chemicals manufactured” and that “the

waste waters of all organic pesticide chemicals can be

treated or controlled to the levels documented in the

Agency’s data base.” App. C, infra, 64a.

No opportunity was afforded for comment on the

major changes in the final regulations or on the new

data on which those changes were based. Petitioners

argued in the Court of Appeals that EPA should have

issued notice for public comment on the proposed re-

visions, on the rationale for the revisions, and on the

new, expanded data base said to support the revised

regulations. Eli Lilly argued that it had not commented

on the interim final regulations or filed a petition for

review of those regulations because it considered them

reasonable as applied to its only pesticide manufactur-

ing plant at Lafayette, Indiana; thus, Eli Lilly contended

that, by making the final regulations substantially more

7

»

stringent without notice to allow public comment, EPA

deprived Eli Lilly of an opportunity to comment on the

regulations and the basis for those regulations.

In its decision the court of appeals stated the following

principle to be applied in determining whether EPA

had complied with the Administrative Procedure Act

(“APA”) :

Even substantial changes in the original plan may be

made so long as they are “in character with the or-

iginal scheme” and “a logical outgrowth” of the

notice and comment already given. [598 F.2d at 642;

App. A, infra, 7a (citation omitted) .]

The court held that the “essential inquiry is whether

the commenters have had a fair opportunity to present

their views on the contents of the final plan” and whether,

“given a new opportunity to comment, commenters would

not have their first occasion to offer new and different

criticisms which the Agency might find convincing’. Id.

at 642; App. A, infra, 7a-8a (footnote and citation

omitted).

The court of appeals first dealt with EPA’s deter-

mination to combine the three interim final subcate-

gories for organic pesticides into a single subcategory.

The court noted EPA had acted contrary to industry

comments, which had criticized the interim final regula-

tions and which had urged EPA to expand the number

of subcategories. Jd. at 643; App. A, infra, 9a. The

court reasoned that it “should be clear to commenters

when they criticize a regulatory scheme that if the

agency accepts those criticisms, a new scheme will be

substituted” and the “commenters cannot claim they had

no notice to propose and discuss alternatives”. Id. at 643;

App. A, infra, 9a-10a. “[T]hough EPA’s solution was

not the one for which industry argued, it was suggested

by and, in part, a logical outgrowth of industry’s com-

ments.” Jd. at 648; App. A, infra, 10a. Therefore, the

court concluded that EPA was not required to give notice

Ee ee ea’

8

of the decision to eliminate subcategories for organic

pesticides and the industry was not entitled to comment

thereon.

“For the same reasons,” the court of appeals rejected

the contention that EPA should have allowed further

opportunity to comment on its determination that all

pesticides can be treated to a single level because the

possibility of that determination had been “clearly sig-

nalled in the interim regulations” since the “industry’s

comments plainly suggested that treatability ought to be

taken into account.” Id. at 644; App. A, infra, lla (foot-

note omitted). Therefore, the court concluded that EPA

was not required to permit comment on its determina-

tion or on the data and assumptions underlying that

determination.

The court of appeals also upheld EPA’s failure to

allow comment on the new data relied upon by EPA

and on the inferences from those data which led EPA

to make major changes in the regulations:

We must decide whether using new data that re-

duced the effluent limits for many of the producers

deprived the public of a fair opportunity to present

views on the final data base. If the data used and

disclosed for the interim regulations presented the

issues for comment, then there is no need to seek new

comment even though significant quantitative differ-

ences result. [Id. at 645; App. A, infra, 138a.]

The court concluded that the disclosure of information

with the interim final regulations permitted the industry

to comment “on the importance of different processes,

products, and volumes” and “to collect data at their own

plants, analyze it, and submit it to EPA.” Id. at 645;

App. A, infra, 14a. “[Wle think it was far more im-

portant for EPA to solicit comments on how it intended

to collect and use data than on the data itself”. Jd. at

645; App. A, infra, 15a. Therefore, the court concluded

that EPA’s reliance on the new data did not require the

issuance of a further notice for public comment.

In reviewing the regulations and the determinations

underlying the regulations, the court of appeals deferred

to the expertise of the Agency and imposed a “heavy

burden” on petitioners of persuading the court that EPA

had erred. Id. at 649-50, 652; App. A, infra, 28a-24a,

28a. In the absence of an agency determination during

the rulemaking process on issues raised by the petitioners,

the court of appeals conducted its own review of the rec-

ord or assumed that EPA had given appropriate con-

sideration to the matter. Id. at 649, 656 nn. 34, 35 & 37;

App. A, infra, 22a; 37a nn. 34 & 35, 38a-39a n. 37.

REASONS FOR GRANTING THE PETITION

I. THE ISSUES PRESENTED TO THIS COURT ARE

IMPORTANT ISSUES WHICH SHOULD BE RE-

SOLVED BY THE COURT TO PROVIDE GUIDANCE

TO THE COURTS OF APPEALS AND TO THE

ADMINISTRATIVE AGENCIES.

This case raises important issues which have not pre-

viously been addressed by this Court and the resolution

of which is necessary in order to provide guidance to

the courts of appeals and to the administrative agencies.

The courts of appeals have had to deal increasingly with

the notice-and-comment requirements of the APA. See,

e.g., National Crushed Stone Association v. Environ-

mental Protection Agency, 601 F.2d 111 (4th Cir.

1979) ; Weyerhaeuser Corp. v. Costle, 590 F.2d 1011

(D.C. Cir. 1978); United States v. Nova Scotia Food

Products Corp., 568 F.2d 240 (2d Cir. 1977) ; American

Iron and Steel Institute v. Environmental Protection

Agency, 568 F.2d 284 (3d Cir. 1977) ; American Frozen

Food Institute v. Train, 539 F.2d 107 (D.C. Cir. 1976).

There is a high degree of probability that the issue

will arise even more frequently in the future. For ex-

ample, pursuant to an amended Consent Decree entered

by the United States District Court for the District of

|

10

Columbia, EPA is obligated to promulgate regulations

establishing effluent limitations and other requirements

for thirty-four major industries by May 1981. Natural

Resources Defense Council v. Costle, 12 E.R.C. 1833

(D.D.C. 1979), appeal docketed, No. 79-1478 (D.C. Cir.

May 9, 1979). In implementing that obligation, the

Agency has initiated the practice of proposing regulations

which broadly suggest that it will consider alternatives

to the proposal and which clearly indicate that it will

compile additional information prior to promulgating

final regulations. See 44 Fed. Reg. 38745, 38764, 38765,

38766 (July 2, 1979) (proposed regulations for the

leather tanning industry). This Court should resolve the

conflict among the courts of appeals and provide guidance

to the Agency and the courts of appeals as to the Agen-

cy’s obligation under the APA to issue notice for public

comment on substantially revised regulations based on

new or additional data and to the courts of appeals on the

appropriate role of the reviewing court when regulations

are based in part on such new data.

II. THE FIRST CIRCUIT’S DETERMINATION THAT

THE ADMINISTRATOR COMPLIED WITH THE

NOTICE-AND-COMMENT REQUIREMENT OF THE

APA CONFLICTS WITH THE DECISIONS OF

OTHER COURTS OF APPEALS AND IS INCOR-

RECT.

A. The Regulations Were Substantially Changed on

_ the Basis of New Data.

The final regulations for the single, collapsed organic

pesticide subeategory are substantially more stringent

than the interim final regulations for the organo-nitrogen

pesticide subcategory and are premised on an expanded

and different data base. The percentage by which the

interim final regulations as applied to waste water from

the manufacture of trifluralin and other organo-nitrogen

pesticides were reduced is shown in the following table:

il

Reduction in E fluent Limitations

From Interim Final to Final Regulations

30-Day Average Daily Maximum

Pesticides —75 percent —47 percent

BOD, — 84 percent —51 percent

COD —57 percent —57 percent

These major changes in the interim final effluent limi-

tations were premised on an “expanded data base” (App.

C, infra, 64a, 67a) and EPA’s “reexamination” of the

regulations in light of that expanded data base (App.

C, infra, 87a-88a). As noted by the court of appeals, the

expanded data base resulting from EPA’s “further re-

search” was the justification for EPA’s critical determi-

nation that the waste waters of all pesticide plants can

be treated to the same level, for EPA’s elimination of

the interim final subcategories for organic pesticides,

and for EPA’s reduction of the effluent limitations. 598

F.2d at 643; App. A, infra, 9a. A particularly important

basis for the EPA determination was data collected on

existing carbon treatment plants by the Agency’s con-

tractor, ESE, after promulgation of the interim final

regulations. As emphasized by the First Circuit, “[i]f

ESE’s work is not reliable, then the final limitations can-

not stand’. Id. at 646; App. A, infra, 16a. EPA also

relied on its new examination of literature on treatment

by carbon adsorption and hydrolysis,’ on laboratory stu-

dies conducted by ESE, and on other data compiled and

evaluations made subsequent to the publication of the

interim final regulations. EPA did not issue public notice

inviting comment on the expanded data base for the

5 These twc types of treatment were identified by EPA as the

technologies whose use would allow the effluent limitations for

pesticides to be met. Jd. at 651; App. A, infra, 28a. The court of

substantially revised regulations. It simply promulgated

final revised regulations relying on that expanded data

base.

In deciding that the Administrator had complied with

the APA, the court of appeals cited its prior decision

in South Terminal Corp. v. Environmental Protection

Agency, 504 F.2d 646 (1st Cir. 1974). At issue in

South Terminal were the EPA regulations for attaining

the Clean Air Act’s national ambient air quality stand-

ards in Boston by reducing vehicular traffic. The notice

of proposed rulemaking included specific measures for

achieving that goal. The notice also stated that alterna-

tives were being considered and identified certain alterna-

tives. Id. at 657. The final regulations adopted alterna-

tives, including a freeze on the number of parking spzces

at Logan Airport and other locations, which had not been

identified in the notice of proposed rulemaking. The

First Circuit held that the Administrator’s notice of the

proposed rules constituted sufficient notice to support his

ultimate decision to adopt a different approach because

the “notice left no doubt that EPA would consider all

reasonable alternatives for cutting down vehicle use.”

Id. at 659. Thus, under the First Circuit’s decision in

South Terminal, a commenter which knew or should

have known that the agency will consider alternatives

to the initial proposal is not entitled to notice of or

to comment on the alternatives finally selected no matter

how much the alternative differs from the proposal.

The court of appeals in this case applied the principle

developed in South Terminal in holding that interested

persons should have anticipated that criticisms of the

EPA’s interim final subcategories could lead to the al-

ternative of eliminating subcategories even though EPA

never disclosed an intent to consider that alternative.

The First Circuit extended the rationale of Sowth Termi-

nal by holding that interested persons are not entitled to

notice of and an opportunity to comment on the new

data relied upon by EPA in establishing the final regula-

tions if the data disclosed with a proposed (or interim

final) regulation reveal the general issues as to the use

of data and provide sufficient information for com-

menters to generate additional data for submission and

use by the agency.

B. The Decision Is In Conflict With Decisions of the

Courts of Appeals for the Second, Fourth, and

District of Columbia Circuits.

The First Circuit’s decision conflicts with National

Crushed Stone Association v. Environmental Protection

Agency, 601 F.2d 111 (4th Cir. 1979), Weyerhaeuser

Corp. v. Costle, 590 F.2d 1011 (D.C. Cir. 1978),

and United States v. Nova Scotia Food Products Corp.,

568 F.2d 240 (2d Cir. 1977), insofar as it holds that

EPA was not required to issue notice and allow public

comment on substantially revised regulations based on

new data and information.®

In National Crushed Stone, the Agency had modified

the interim final regulations for crushed stone and con-

struction sand and gravel facilities by increasing the 30-

day average effluent limitation for total suspended solids

(“TSS”) and by adding a maximum daily effluent limita-

tion for TSS. 601 F.2d at 115. The changes were made

on the basis of data collected by the Agency’s contractor

(Versar) on which there was no opportunity for public

comment. Jd. at 117. The Fourth Circuit held:

The objections go on and on, but enough have been

related to show that they are far from frivolous,

and while EPA will undoubtedly take issue with the

report of [the petitioners’] engineer, we need not,

and do not, decide whether the objections raised in

the engineer’s report are valid. What we do decide

6 The First Circuit’s decision also is contrary to a Ninth Circuit

decision on an analogous issue. See Marathon Oil Co. v. Environ-

mental Protection Agency, 564 F.2d 1253, 1271 (9th Cir. 1977).

14

is that the mistakes in the use of the Versar data, if

any mistakes there were, were shown by the report

to be of possible significance in the formulation of the

final regulations. ... The fact that the petitioners,

and just as importantly the public, had no opportun-

ity to comment on the use of the Versar data prior to

the promulgation of the final regulations in the face -

of serious questions concerning the validity of their

use is reason to remand the regulations for further

consideration. ]Jd. at 119 (footnote omitted).]

In direct contrast, the First Circuit held that the

APA is satisfied if the notice informs the public of the

general issues relating to data use and provides the

framework for the affected industry to generate data for

submission to EPA. Under the First Circuit’s rule, no

obligation is imposed on the Agency to permit public

comment on its new or expanded data base.

In Weyerhaeuser, EPA secured new data after issu-

ing the interim final effluent regulations and after

the close of the public comment period. 590 F.2d at 1029.

Using that data, it recalculated the biochemical oxygen

demand (BOD) effluent limitation for acetate grade dis-

solving sulfate pulp mills for inclusion in the final

effluent regulations which were the subject of the peti-

tions for review. Jd. at 1029. The court held that the

Agency’s procedures “improperly denied petitioners the

opportunity to comment on a significant part of the

Agency’s decisionmaking process as required by Section

553” because the “figures variously relied upon by the

Agency must be validated, if at all, by reference... to

certain data . . . obtained by the Agency after the op-

portunity for public comment had lapsed... .” Id. at

1030-31 (citations omitted). The court of appeals stated

that the data which “were not subject to prepromul-

gation public scrutiny are factual matters. As such, they

are especially subject to verification through the notice

15

and comment process and less acceptably removed there-

from.” Id. at 1030 n. 26.

The District of Columbia Circuit’s decision in Weyer-

haeuser follows its prior decision in Portland Cement

Association v. Ruckelshaus, 486 F.2d 375 (D.C. Cir.

1973), cert. denied, 417 U.S. 921 (1974). In Portland

Cement, the court of appeals found “a critical defect in

the decisionmaking process in arriving at the standard

under review in the initial inability of petitioners to

obtain—in timely fashion—the test results and procedures

used on existing plants which formed a partial basis for

the emission control level adopted” in the standard of

performance for new portland cement plants. 486 F.2d

at 392. The court concluded:

It is not consonant with the purpose of a rule-

making proceeding to promulgate rules on the basis

of inadequate data, or on data, that, [in] critical de-

gree, is known only to the agency. [J/d. at 393.]

In direct contrast, the First Circuit held that inviting

comments on new data used by the Agency in establish-

ing revised final regulations is unimportant. The First

Circuit attempted to distinguish Weyerhaeuser on the

ground that the formula used by EPA to calculate the

effluent limitations in that case was not set forth or

explained in the record. 598 F.2d at 646 n. 15; App. A,

infra, 15a n. 15. However, the District of Columbia Cir-

cuit clearly held that an opportunity for public comment

on the data was required by the APA and that the fact

that the calculations were not reflected in the record con-

stituted additional grounds for remand.

In Nova Scotia Food Products, interested persons “were

not informed of the scientific data, or at least a selection

of such data deemed important” by the Food and Drug

Administration in establishing processing standards for

fish products. 568 F.2d at 251. In holding that the notice

16

of proposed rulemaking was deficient under the APA for

failure to disclose such scientific information, the Second

Circuit found:

Scientific research is sometimes rejected for diverse

inadequacies in methodology; and statistical results

are sometimes rebutted because of a lack of ade-

quate gathering technique or of supportable extra-

polation. Such is the stuff of scientific debate. To

suppress meaningful comment by failure to dis-

close the basic data relied upon is akin to rejecting

comment altogether. [568 F.2d at 252 (emphasis

added) .]

The First Circuit here recognized that the issues posed

difficult scientific questions, including those related to

the validity of the critical ESE data. The court knew it

could not “play the role of Superchemist” to resolve

those issues. 598 F.2d at 649; App. A, infra, 23a. None-

theless, the court held that notice and comment were not

required on fundamental scientific and technical issues

relating to the new data relied upon by EPA.

C. The First Circuit Erred in Deciding that EPA Had

Complied With The APA.

There is substantial agreement among the courts of

appeals that regulations are not necessarily legally de-

fective if they differ, even substantially, from the regu-

latory proposal published for public comment. See, e.g.,

South Terminal Corp., 504 F.2d at 659; International

Harvester Co. v. Ruckelshaus, 478 F.2d 615, 682 (D.C.

Cir. 1973); California Citizens Band Association v.

United States, 375 F.2d 48, 48 (9th Cir.), cert. denied,

389 U.S. 844 (1967). However, no other case invoking

the notice-and-comment issue has concerned a change in

regulations which appears comparable in magnitude to

the 50 to 85 percent reduction in allowable discharges

from organo-nitrogen pesticide manufacturing plants as

occurred in this case. The substantiality of the modifi-

et

17

cation of a regulation must be a factor to be considered

in applying the APA. The First Circuit erred in failing

to consider that factor.

The First Cireuit construed the APA as not requiring

notice for comment prior to adoption as a final regulation

of an alternative that is radically different from the pro-

posed regulation as long as the Agency indicates in the

initial notice that it will consider all possible alternatives.

Such an interpretation provides an agency with an un-

limited opportunity to preclude public comment by the

simple expedient of issuing a “comprehensive notice”

that it is considering all possible alternatives to its pro-

posal. See South Terminal Corp., 504 F.2d at 659.

Most importantly, the First Circuit’s decision in this

case obviates the purpose and function of the notice-and-

comment requirements of the APA. This Court has not

had occasion to provide specific guidance on the legisla-

tive purpose of the notice-and-comment requirement.

The courts of appeals, however, have identified three

important functions of Section 4. First, the notice allows

interested parties an opportunity to offer informed criti-

cism and comments. See, e.g., Ethyl Corp. v. Environ-

mental Protection Agency, 541 F.2d 1, 48 (D.C. Cir.

1976), cert. denied, 426 U.S. 941 (1976); Portland Ce-

ment Association, 486 F.2d at 392-94. Second, giving

interested persons a meaningful opportunity to comment

enables the Agency promulgating the rules “to educate

itself before establishing rules and procedures which

have a substantial impact on those regulated”. Texaco,

Ine. v. Federal Power Commission, 412 F.2d 740, 744

(8d Cir. 1969). Third, the dialogue of comment and

agency response to comment assists the reviewing court in

deciding difficult issues. Home Box Office, Inc. v. Federal

Communications Commission, 567 F.2d 9, 35-36 (D.C.

Cir. 1977) ; see Weyerhaeuser Corp., 590 F.2d at 1028;

18

cf. Marathon Oil, 564 F.2d at 1271 n. 54. (“[C]omment

is often an invaluable source of information to a review-

ing court attempting to evaluate complex statistical and

technological decisions.’’)

The decision of the First Circuit in this case is not

consistent with those objectives. The First Circuit per-

ceived the principle role of industry member comment as

narrowly confined to providing the Agency with addi-

tional information and data on their plants in order to

provide the Agency with the broadest possible data base.

The First Circuit considered it far less important, and

not sufficiently important to require further notice for

comment, that the industry and other interested persons

comment on the data compiled by the Agency (including

the validity of that data) or on the Agency’s scientific

and technical inferences from the data. As a result, the

First Circuit’s decision unnecessarily cribs the scope of

the subject matter which should be subject to informed

criticism and comment.

The First Circuit assumes that the Agency is not in

need of and would not benefit from the education result-

ing from comment, favorable or critical, on the data be-

fore it and the conclusions which reasonably can be drawn

from that data.

Finally, the First Circuit’s decision deprives a review-

ing court of a balanced and complete record upon which

to assess sometimes difficult and complex issues. This

latter point is demonstrated dramatically in this case by

the difficulty which the First Circuit had in resolving the

issues before it and by its unique and inappropriate ap-

proaches toward resolving these issues on the basis of an

administrative record which had not been subject to

public scrutiny and comment. See pages 22-27 infra.

19

D. Eli Lilly is Particularly Harmed By The First

Circuit’s Ruling.

The First Circuit’s decision applies with particular

inequity to Eli Lilly. Eli Lilly’s concern was for a single

pesticide, trifluralin. Upon review of the interim final

effluent limitations, Eli Lilly concluded that they were

reasonable as applied to the production of trifluralin at

its Lafayette, Indiana plant. Eli Lilly was not in a posi-

tion to comment on whether the interim final regulations

were reasonable or unreasonable for the industry as a

whole or as applied to the production of pesticides by

other manufacturers in a diverse industry. Therefore,

Eli Lilly did not file comments on the interim final regu-

lations or a petition for review of the interim final

regulations.

Although those facts specific to Eli Lilly were set forth

for the First Circuit, the court of appeals did not spe-

cifically address them.’ By necessary implication, the

First Circuit held that the interim final regulations con-

stituted sufficient notice of the final regulations to permit

Eli Lilly an adequate opportunity to participate in the

rulemaking for the same reasons that it concluded that

those who did comment and criticize the interim final

regulations had sufficient notice of the possible outcome

of their comments: “The commenters cannot claim they

had no notice to propose and discuss alternatives.” 598

F.2d at 648; App. A, infra, 10a. It is unreason-

7 The court did state that “[rJegulatory targets have no guaran-

tee that proposed effluent limits, which they are capable of meeting,

will stay the same.” 598 F.2d at 646; App. A, infra, 15a. The issue,

however is not whether Eli Lilly could rest in complete assurance

that the effluent limitations applicable to its plant would remain the

same. Rather the issue is whether, under the procedures adopted by

the Agency, Eli Lilly was accorded the opportunity to participate in

the rulemaking required by the APA.

8 Any suggestion that Eli Lilly should have recognized that the

Agency might collapse the subcategories because one commenter, as

the court of appeals read its remarks, saw that possibility would be

unreasonable and contrary to the Third Circuit’s decision in Wagner

Elec. Corp. v. Volpe, 466 F.2d 1018, 1019 (3d Cir. 1972).

20

able to expect that Eli Lilly should have hypothesized

alternative schemes which EPA might adopt to the de-

triment of Eli Lilly; that Eli Lilly should have sub-

mitted comments in opposition to those schemes; or that

Eli Lilly should have developed alternative approaches

to the interim final subcategories which would result in

reasonable effluent limitations for trifluralin.

Most importantly, however, the First Circuit’s decision

deprived Eli Lilly of the opportunity to comment on the

determination which had an adverse impact on Eli Lilly

—the determination based on an expanded data base to

collapse the three interim final subcategories into one

subeategory and dramatically reduce the effluent limita-

tions for trifluralin. In short, according to the court of

appeals’ theory, Eli Lilly was obligated to assume that

the Agency would alter its course in a manner contrary

to Eli Lilly’s interests and to comment accordingly on in-

terim final regulations to which it did not object. But Eli

Lilly was not entitled to comment on the changes in

methodology, assumptions, or data which were the basis

for the final regulations which Eli Lilly did find unrea-

sonable and objectionable.®

® The fact that data from Eli Lilly’s plant was part of the Agen-

cy’s expanded data base tends to reinforce the conclusion that the

First Circuit has unjustifiably narrowed the notice-and-comment

requirements of the APA. Eli Lilly operates a carbon treatment

system for waste water from its trifluralin process. At EPA’s re-

quest, ESE sampled the waste water going to Eli Lilly’s ..rbon

treatment system and the treated effluent from the carbon treatment

system in January 1977. Eli Lilly believed that carbon treatment

was being considered by EPA as a basis for the second-stage regu-

lations implementing requirements for best available technology and

that the information was being collected for the purpose of prepar-

ing such proposed regulations. See note 1 supra. In announcing

the interim final regulations, EPA “emphasized” that it planned to

issue “in the near future” second-stage regulations which would

require ‘substantial further reductions in pollutants discharged” by

the use of “advanced technology.” 41 Fed. Reg. at 48091. One of the

advanced technologies cited was carbon adsorption. 7d. at 48091.

[Footnote continued on page 21]

® [Continued ]

At no time did EPA inform Eli Lilly that the ESE data would be

used in the final first-stage regulations or would be cited as evidence

that substantially reduced first-stage limitations were attainable

because, on their face, the data indicated that Eli Lilly’s discharge

of pesticides is below the level permitted by the final effluent

limitations.

Eli Lilly was afforded only a limited opportunity to comment on

the ESE numbers and no opportunity to comment on EPA’s inter-

pretation and use of the data. The ESE data were furwarded to

Eli Lilly and Eli Lilly, noting the differences between its analytical

results and ESE’s, suggested further dialegue on the analytical

validity of the survey data. The invitation was not accepted and

the matter remained unresolved when the final regulations were

promulgated.

Eli Lilly argued in the court of appeals (1) that the ESE data

should not have been used because of their possible analytical in-

validity; (2) that data from a survey covering the first four days

of a seven-day treatment cycle of a new carbon treatment system

should not have been cited as representing consistent, long-term

performance of the treatment system; and (3) that, because ESE’s

survey conducted in accordance with EPA’s request, covered only

treated effluent from the carbon system and did not include certain

waste streams which bypassed the carbon system, the ESE data

did not demonstrate that Eli Lilly could achieve the final effluent

limitations. The First Circuit rejected these arguments in large

part because it found the record to be ambiguous and without sup-

port for them. Jd. at 648, 653; App. A, infra, 20a, 3la. Had EPA

issued a further notice for public comment on the revised regula-

tions and on the expanded data base, Eli Lilly could have provided

further information on the analytical invalidity of the data and

would have had its first opportunity to comment on EPA’s interpre-

tation and use of that data.

Ill. EVEN IF IT WERE ASSUMED THAT EPA WAS

NOT REQUIRED TO ISSUE NOTICE FOR PUBLIC

COMMENT ON THE REVISED REGULATIONS,

THE COURT OF APPEALS’ DECISION TO DEFER

TO EPA’S DETERMINATIONS BASED ON AN EX-

PANDED DATA BASE WAS INCORRECT AND IN

CONFLICT WITH THE DECISION OF ANOTHER

COURT OF APPEALS AND RESULTED IN THE

COURT SUBSTITUTING ITS JUDGMENT FOR

THAT OF EPA.

A. The Court of Appeals Deferred to EPA on Matters

Not Subject to Public Comment, and Conducted a

De Novo Review of New Data and Information.

The First Circuit recognized that the notice-and-com-

ment requirements are linked to the standard to be

applied in reviewing the Agency’s action because that

requirement “supports the assumption we make with

regard to EPA’s substantive decisions that those decisions

are in fact the product of informed, expert reasoning

tested by exposure to diverse public comment.” 598 F.2d

at 641; App. A, infra, 6a. The court stated:

We will not remand [to the Agency] so long as the

Agency has explained the facts and policies on which

it relied; the facts have some basis in the record;

and a reasonable person could make the judgment

the Agency made. [J/d. at 652; App. A, infra, 28a.]

The court held, erroneously, that interested persons

had an opportunity to comment on alternative sub-

categorization schemes that EPA might adopt. The court

of appeals did not, and could not, suggest that the

expanded data base upon which EPA relied and the tech-

nical and scientific inferences which it drew from those

data were “tested by exposure to diverse public com-

ment.” Nonetheless, the court deferred to determina-

tions made by EPA which were based on such untested

data and inferences.

The following are illustrative of the court’s deference

to EPA:

Petitioners argued that, at best, EPA had data on

only a few of the forty-nine pesticides covered by the

regulations (see note 2 supra) and, therefore, could not

reach the critical conclusior that all pesticides can be

treated to the same level. Noting that EPA’s expanded

data base included technical literature references on

the treatment of pesticides, the court deferred to EPA’s

judgment, stating: ;

[T]he Agency is entitled to use its chemical exper-

tise to conclude that compounds’ manufacturing proc-

esses, chemical structures, and physical properties

are sufficiently related so that if one is treatable the

others are likely to be as well.... We conclude...

that the Agency permissibly decided that the tech-

niques are broadly applicable to facilities manufac-

turing the 49 pesticides discharge of which is regu-

lated. [598 F.2d at 656; App. A, 36a-37a. (foot-

note and paragraphing omitted).]

The court rejected petitioners’ arguments that EPA erred

in inferring from the literature, particularly literature

on laboratory studies, the result which could be achieved

by full scale treatment systems. The court responded that

it is “up to the Agency experts to decide whether relaxing

the laboratory conditions would so change the result

that the pesticide could not be treated by industry.” Id.

at 652 n. 27; App. A, infra, 29a-30a n. 27. Most astonish-

ing, the court of appeals conceded that it could find “no

mention” in the expanded data base or EPA’s evaluation

of that data base of ten of the forty-nine regulated pesti-

cides, but was “willing to assume from EPA’s general

language that it reached a similar conclusion as to these

ten pesticides as well.” Jd. at 656 n. 34; App. A, infra,

37a n. 34 (emphasis added) .’®

1 The court of appeals made a number of additional ‘“assump-

tions” that EPA had properly applied its expertise in evaluating and

using the information before it. See id. at 656-57 nn. 35 & 37; App.

A, infra, 37a n. 35, 38a-39a n. 37.

24

Petitioners challenged the validity of the data collected

by EPA’s contractor, ESE. The court of appeals con-

cluded that “[i]Jf ESE’s work is not reliable, then the

final limitations cannot stand.” Jd. at 646; App. A,

infra, 16a. The ESE data, and particularly the labora-

tory documents from which their validity must be as-

sessed, were not made available for public review during

the rulemaking." The court of appeals found EPA’s

response in its brief and supplemental memorandum to

be an inadequate response to petitioners’ arguments.

Rather than remand the regulations, the court adopted

a new and unique approach toward reviewing agency

action: “We have therefore conducted our own review.”

Id. at 649; App. A, infra, 22a. The court conceded that

its independent review was “necessarily superficial” and

inconclusive:

We cannot be sure that these references [to the

ESE records] are an adequate response to criti-

cisms levied at ESE’s general control procedures.

But we cannot play the role of Superchemist. Peti-

tioners bear an extremely heavy burden if they desire

to demonstrate that the results of a rulemaking pro-

cedure are infested with fatal flaws of laboratory

practice. Our review, partial and facial though it

is, satisfies us of the probability that EPA was jus-

tified in basing its regulations on ESE’s work. [Jd.

at 649-50; App. A, infra, 23a-24a (footnote omit-

ted) .]

B. The First Circuit Erred in According Judicial

Deference to EPA Determinations Based on Data

and Information Which Had Not Been Tested By

Public Comment.

The First Circuit’s decision conflicts with the District

of Columbia Circuit’s decision in Weyerhaeuser Corp. V.

11 Indeed, a complete set of laboratory documents was not turned

over to EPA or petitioners by ESE until after oral argument before

the First Circuit. Jd. at 646; App. A, infra, 16a.

Costle, 590 F.2d 1011 (1978). The First Circuit cited

Weyerhaeuser in support of the standard of review to be

applied. 598 F.2d at 647; App. A, infra, 18a-19a. How-

ever, the First Circuit declined, without explanation, to

follow the rule in Weyerhaeuser that an agency determi-

nation is not entitled to a presumption of rationality

when the data upon which that determination is based

have not been subject to public scrutiny. The court in

Weyerhaeuser stated:

This denial of an opportunity for comment on these

facts further undermines our usual assumption that

notice and comment rulemaking, by virtue of its ac-

cessibility to public scrutiny, achieve rational re-

sults.

27... [I]t is our place only to review actions

actually and properly taken by the Agency. If that

action is improper and if we cannot be sure that un-

der correct procedures the Agency would have

reached the same conclusion, we cannot characterize

that defect as harmless. [590 F.2d at 1931 & n. 27

(original emphasis) .]

The District of Columbia Circuit’s decision in Weyer-

haeuser is analogous to this Court’s decision in Citizens

to Preserve Overton Park v. Volpe, 401 U.S. 402 (1971).

If the reviewing court determined that the explanation

accompanying the initial agency decision was deficient,

this Court suggested that the reviewing court require the

agency to prepare additional findings explaining the basis

for its action. The Court recognized that such findings

would be prepared outside the normal course of agency

proceedings and cautioned that they should not be ac-

corded the usual deference: the findings “will, to some

extent, be ‘post hoc rationalizations’ and thus must be

reviewed critically”. 401 U.S. at 421.

26

C. The First Circuit Impermissibly Substituted Its

Judgment for That of the Agency.

On a number of occasions, this Court has emphasized

that a reviewing court may not substitute its judgment

for the judgment of the agency whose action is under

review. Bowman Transportation, Inc. v. Arkansas-Best

Freight Systems, Inc., 419 U.S. 281, 285 (1974); Fed-

eral Trade Commission v. Sperry & Hutchinson Co., 405

U.S. 233, 249 (1972) ; Citizens to Preserve Overton Park,

401 U.S. at 416.

The First Circuit was propelled into that forbidden

role by its decision to review the regulations on the basis

of a record incompletely tested by exposure to public

comment and often devoid of EPA response to the com-

ments which would have been made.

The court made “assumptions” that EPA had ration-

ally resolved issues raised by petitioners when there was

no evidence in the record that EPA had even considered

the issues. The court conducted an unprecedented inde-

pendent review of laboratory documents which EPA did

not receive until after it had promulgated the final

regulations. Even then, the court failed to reach a defini-

tive conclusion as to the validity of the critical laboratory

data. Yet, it upheld EPA’s use of the data on the ground

that petitioners had not carried their heavy burden of

persuading the court that EPA had acted impermissibly.”

EPA did not reach a judgment that data supported by

its contractor, ESE, were reliable. The court of appeals

made that judgment after a “partial! and facial” review.

12The First Circuit’s procedure contrasts with the following

cbservation of Judge McGowan: “[T]he realities of judicial scru-

tiny . . do not contemplate that the court itself will, by a laborious

examination of the record, formulate in the first instance the sig-

nificant issues faced by the agency and articulate the rationale of

their resolution.” Automotive Parts & Accessories Ass’n. Vv. Boyd,

407 F.2d 330, 338 (D.C. Cir. 1968).

Mah icieh, CaS rsearwee: 6? he

27

598 F.2d at 650; App. A, infra, 24a. The court then

upheld EPA’s use of the data because the petitioners had

not carried their heavy burden of persuading the court

that the court’s uncertain conclusion as to the reliability

of the ESE data was in error.

This Court rejected judicial excursions into the admin-

istrative domain in Federal Power Commission v. Trans-

continental Gas Pipe Line Corp., 423 U.S. 326 (1976):

At least in the absence of substantial justification

for doing otherwise, a reviewing court may not after

determining that additional evidence is requisite for

adequate review, proceed by dictating to the agency

the methods, procedures, and time dimension of the

needed inquiry and order the results to be reported

to the court without opportunity for further con-

sideration on the basis of the new evidence by the

agency. Such a procedure clearly runs the risk of

‘propel [ling] the court into the domain which Com-

gress has set aside exclusively for the administrative

These consolidated petitions have been brought by

eleven manufacturers of pesticides’ against the respon-

dent, the Administrator of the Environmental Protection

Agency (EPA or Agency), seeking review of regulations

governing the discharge of pollutants by the pesticide

industry. 40 C.F.R. Part 455, 43 Fed. Reg. 17776 and

43 Fed. Reg. 44845 (1978). An industry organization,

* Of the District of Massachusetts, sitting by designation.

1 The petitioners are BASF Wyandotte Corp., Diamond Shamrock

Corp., FMC Corp., Olin Corp., American Cyanamid, Union Carbide

Corp., E. I. duPont de Nemours & Co., Inc., Ciba-Geigy Corp., Mon-

santo Co., Dow Chemical Co., and Eli Lilly and Co.

4a

the National Agricultural Chemical Association (NACA),

has intervened. The Federal Water Pollution Control Act

states as a “national goal that the discharge of pollutants

into the navigable waters be eliminated by 1985.” 33

U.S.C. § 1251(a) (1). These regulations are promulgated

in respe” se to Congress’ direction that the Administrator

provide guidelines for the effluent reduction possible

through implementation of the “best practicable control

technology currently available’. 33 U.S.C. §§ 1311(b)

(1) (A) and 1314(b) (1).?

In 1974 the Agency hired an outside contractor, Roy F.

Weston, Inc. (Weston), to analyze the industry. Weston

submitted its final report in December of 1975. In early

1976 EPA hired a second contractor, Environmental Sci-

ence and Engineering, Inc. (ESE), to evaluate Weston’s

work. ESE determined that Weston’s work needed im-

provement and undertook its own study of the industry.

In late 1976 EPA published interim final regulations that

were immediately effective, but on which EPA invited

public comment. 41 Fed. Reg. 48087 (1976). An interim

development document and an economic analysis explain-

ing the derivation of the interim regulations were also

released.

In the months following publication of the interim reg-

ulations EPA received comments on many issues raised

by the regulations. EPA also collected additional data

and conducted further research. In early 1978 the final

regulations were published, 43 Fed.Reg. 17776 (1978),

as were a final development document and economic anal-

ysis. The final regulations differed from the interim

regulations in a number of significant ways. The one

principally relevant in this case is that EPA finally sub-

divided the industry into three subcategories: (1) Or-

ganic Pesticide Chemicals Manufacturing; (2) Metallo-

Organic Pesticide Chemicals Manufacturing; and (3)

Pesticide Chemicals Formulating and Packaging. In the

interim regulations the organic pesticide subcategory

had been further divided into three subcategories. For

the second and third final subcategories the regulations

permit “no discharge of process waste water pollutants

into navigable waters.” 40 C.F.R. §§ 455.82 and 455.42.

For the first subcategory, 40 C.F.R. § 455.22 limits the

pounds or kilograms of chemical oxygen demand (COD),

biological oxygen demand (BOD), total suspended solids,

and pesticide chemicals that a plant may discharge per

thousand pounds or kilograms of pesticide produced dur-

ing any one day or any 30 consecutive days. The levels

set are lower than the levels set by the interims for some

producers and higher for others. Also the pH level (the

relative acidity or alkalinity) of the effluent must be

within a set range.

After the final regulations issued, one of the petitioners

filed a motion for reconsideration alleging, among other

things, that analytical techniques were not available to

detect many pesticides at the levels stated in the regula-

tions, EPA reexamined the record and discovered that

Some measurement methods that EPA thought were

available might not be reliable. Accordingly, EPA

amended the regulations so that the pesticide content

of process waste water would be limited for the producers

of only 49 out of several hundred pesticides. 43 F

44845, 44856 (1978). . sin

The first petition for review challenged the interim

final regulations. When the final regulations were pub-

lished we granted permission to amend so as to include

review of the finals. BASF Wyandotte Corp. v. Costle

582 F.2d 108 (1st Cir. 1978). Subsequently the petitions

for review filed in other circuits were transferred to this

circuit. The consolidated petitions assert several pro-

6a

cedural and substantive errors in the regulations and

their promulgation.

I. Organic Pesticide Manufacturing

A. Administrative Procedure Act Compliance

Petitioners’ first complaint is that EPA failed to com-

ply with the requirements of the Administrative Proce-

dure Act in that the final regulations were so different

from the interim final regulations that the interims were

not notice of “either the terms or substance of the pro-

posed rule or a description of the subjects and issues

involved.” 5 U.S.C. § 553(b) (3). This requirement is a

critical one because it supports the assumption we make

with regard to EPA’s substantive decisions that those

decisions are in fact the product of informed, expert rea-

soning tested by exposure to diverse public comment.

Though our review of an agency’s final decision is rela-

tively narrow, we must be strict in reviewing an agency’s

compliance with procedural rules. See Weyerhaeuser Co.

v. Costle, 590 F.2d 1011, 1027-1028 (D.C. Cir. 1978).

In this case EPA issued interim final regulations and

sought comments on them. Industry representatives, gov-

ernment agencies, and others submitted voluminous com-

ments on many aspects of the interim regulations. It is

clear that EPA gave careful consideration to these com-

ments. The Agency summarized the public comment,

together with the Agency responses in the prologue to

the final regulations. 43 Fed. Reg. 17781-85 (1978). The

Agency accepted several suggestions made in comments

critical of the interim regulations. For instance, EPA

deleted some parameters by which the interim regulations

controlled discharges,® abandoned use of COD/BOD ratios

tent of discharges from some pesticide production plants. 41 Fed.

Reg. 48088 (1976).

Ta

to supplement raw waste load data, and tried certain

statistical tests proposed by commenters. EPA further

demonstrated its openness to comments by eliminating,

as we have noted, pesticide discharge limits for all but

49 chemicals in response to information received after

the final regulations were printed.

The procedural rules were meant to ensure meaningful

public participation in agency proceedings, not to be a

straitjacket for agencies. An agency’s promulgation of

proposed rules is not a’ guarantee that those rules will be

changed only in the ways the targets of the rules suggest.

“The requirement of submission of a proposed rule for

comment does not automatically generate a new oppor-

tunity for comment merely because the rule promulgated

by the agency differs from the rule it proposed, partly

at least in response to submissions.” International Har-

vester Co. Vv. Ruckelshaus, 155 U.S.App.D.C. 411, 428,

478 F.2d 615, 632 (1973); Weyerhaeuser Co. v. Costle,

supra, at 1031; American Frozen Food Institute v. Train,

176 U.S.App.D.C. 105, 1382, 539 F.2d 107, 134 (1976).

Even substantial changes in the original plan may be

made so long as they are “in character with the original

scheme” and “a logical outgrowth” of the notice and

comment already given. South Terminal Corp. v. EPA,

504 F.2d 646, 658, 659 (1st Cir. 1974).

The essential inquiry is whether the commenters have

had a fair opportunity to present their views on the

contents of the final plan.‘ We must be satisfied, in other

words, that given a new opportunity to comment, com-

4In the words of the Attorney General’s Manual on the Ad-

ministrative Procedure Act (1947), a contemporary explanation of

the Act’s purposes and provisions, “the notice should be sufficiently

informative to assure interested persons an opportunity to par-

ticipate intelligently in the rule making process.” Jd. at 30. Even

where the Agency could publish the proposed rule itself, the Manual

suggests that it may choose not to, issuing instead “a more general

‘description of the subjects and issues involved.’ ” Jd. at 29.

menters would not have their first occasion to offer new

and different criticisms which the Agency might find

convincing. Weyerhaeuser, at 1031. Thus, where the

final rules “are the result of a complex mix of controver-

sial and uncommented upon data and calculation’, re-

mand may be in order. 7d. Similarly, where the Agency

adds a new pollution control parameter without giving

notice of intention to do so or receiving comments,

there must be a remand to allow public comment. Amer-

ican Frozen Food Institute, supra, 176 U.S.App.D.C. at

133, 5389 F.2d at 135. The question, however, always

requires careful consideration on a case-by-case basis.

The first and principal change complained of is the

Agency’s decision to merge the first three interim sub-

eategories® into a single Organic Pesticide Chemicals

Manufacturing subcategory.® So far as the record dis-

closes, petitioners were not aware of this change until

the final regulations were promulgated and the time for

comment had expired. EPA consolidated the former sub-

categories because it “recognized certain ambiguities were

present in its subcategorization based on chemical struc-

ture. Many pesticides contain more than one functional

group ... and do not fit the former subcategorization

scheme.” 43 Fed.Reg. 17777 (1978). Consequently, “and

5The interim regulations included separate subcategories for

manufacturers of Halogenated Organic Pesticides, Organo-

Phosphorous Pesticides, and Organo-Nitrogen Pesticides.

6 Respondent incorrectly read petitioners’ procedural challenge as

being limited to this change. BASF petitioners’ brief clearly states

other alleged deficiencies in notice:

“EPA should have exposed to public comment its decision to

limit the regulations to those pesticides for which there are

reliable analytical methods, its decision to adopt a single

category for all organic pesticides, its determination that all

pesticides can be treated to a single level regardless of differ-

ences in treatability of particular pesticides and its assess-

ment of the applicability and effectiveness of carbon treatment

and hydrolysis.”

in response to industry comments”, EPA undertook fur-

ther research and found that “the quantities of pollutants

in the effluents of those plants with the properly operated

model technologies installed were similar regardless of

the organic pesticide chemicals manufactured. The

Agency . . . therefore concluded that the waste waters

of all organic pesticide chemicals can be treated or con-

trolled to the levels documented. ... Thus, the final reg-

ulations do not differentiate among halogenated organic,

organo-phosphorus, or organo-nitrogen pesticide chemi-

eals.” Id.

The industry comments were almost unanimous in

condemning the three original subcategories both for

being internally inconsistent and insufficiently differen-

tiated from the other categories.’ Comments presented

statistical tests of EPA’s data, purporting to show that:

the subcategories were not distinguishable from each

other. Comments also pointed to the inclusion of very

different compounds within particular subcategories. The

comments made a strong case against use of the in-

terim subcategories, and EPA decided that the criti-

cism was persuasive. It follows that EPA had to

decide on an alternative unless it was to abandon regula-

tion of the pesticide industry. Industry’s preference

was clear. They wanted EPA to expand the number of

subcategories. They are now aggrieved because EPA

accepted their criticism of the original subcategories but

chose a different solution, collapsing rather than expand-

ting them. Petitioners suggest that EPA’s response took

them entirely by surprise and that EPA had somehow

indicated that the only issue for comments would be

whether three subcategories were enough or there should

be more.

Neither suggestion is grounds for remand. It should be

clear to commenters when they criticize a regulatory

10a

scheme that if the agency accepts those criticisms, a

new scheme will be substituted. The commenters cannot

claim they had no notice to propose and discuss alterna-

tives. And in fact they did so, suggesting a number of

new approaches based on different ways to subcategorize

the industry. In fact, at least one commenter recognized

that if the existing scheme was not defensible, one alter-

native would be to abandon subcategories. This com-

menter, also a petitioner, Monsanto, wrote:

“It is our belief that additional partitioning of chem-

ical groups based on the above environmental impact

factors must be accomplished if the Agency intends

to pursue the subcategorization approach.” App. at

1905. (Emphasis added.)

Clearly Monsanto realized that the Agency would have

to consider alternatives and was not finally committed to

subcategories. Moreover, Monsanto’s response indicates

that the Agency had not misled petitioners into thinking

that they need only state views on the desirability of

more subcategories rather than the undesirability of

fewer.

Another repeated call of the industry commenters was

that the subcategories should be more equitably treated

because the record did not support the significantly dif-

ferent guideline limits assigned to the different sub-

categories.” They should have realized that these crit-

icisms, if accepted, could be resolved, among other ways,

by applying the same limits to all organic pesticides.

Again, though EPA’s solution was not the one for which

industry argued, it was suggested by and, in part, a

logical outgrowth of industry’s comments. They cannot

® Mobay, for instance, expressed its concern that the interim

limitations “for the organo-phosphorus subcategory were based

on prejudiced and . . . inequitable treatment when compared to

the halogenated organics and organo-compounds [sic].” App. at

1755.

lla

now complain because they misread the regulatory wa-

ters, incorrectly anticipated how EPA would react to

their criticisms, and, consequently, submitted comments

that left some things unsaid.

Not only do we think that petitioners had fair notice

that consolidation of subcategories was an issue to com-

ment upon, but we cannot think how their comments

would have differed fundamentally if they had known

what EPA would do. Though they would have had a

different proposition against which to argue, their pro-

posed solutions would, presumably, have been the same

for the same reasons. They might have responded in

greater volume or more vociferously, but they have not

shown us that the content of their criticisms would have

been different to the point that they would have stood

a better chance of convincing the Agency to use more

subcategories. In short, they had a fair opportunity to

present their views on how the industry ought to be

subeategorized. Their real complaint is that EPA re-

jected those views.

For the same reasons, we do not think EPA was obli-

gated to provide further opportunity to comment on “its

decision to limit the regulations to those pesticides for

which there are reliable analytical methods” or “its de-

determination that all pesticides can be treated to a

single level regardless of differences in treatability of

particular pesticides”. To the extent the latter differs

from the decision to consolidate categories, it was clearly

signalled in the interim regulations. As the commenters

pointed out, the interim subcategories were based on

physical structure and each included chemicals of diverse

treatability. The industry’s comments plainly suggested

that treatability ought to be taken into account.’ Sim-

ilarly, as to the former, the interim regulations applied

& Co., App. at 1915.

12a

a limit on the discharge of total pesticides to all manu-

facturers of pesticides. Any manufacturer that had rea-

son to believe its pesticides could not be detected at the

guideline limit had the opportunity to ask the Agency

to change its regulations as to any particular pesticide

or as to all pesticides. The Agency’s receptiveness to such

comments is indicated by the very decision attacked, its

elimination of limits as to all but 49 organic pesticides

when confronted with information showing that others

were not reliably detectible. There was no lack of notice

as to these subjects.

The last point we must address is a different and

more difficult one. One of EPA’s justifications for con-

solidating the subcategories and for reducing the dis-

charge limits for many pesticides was the conclusion,

based in part on “additional raw waste load and treat-

ment data, and additional pilot plant and laboratory

data” that “the waste waters of all organic pesticide

chemicals can be treated or controlled to the levels docu-

mented in the Agency’s data base.” 43 Fed.Reg. at

17777. The BASF petitioners argue that since the EPA’s

conclusions were premised on “new data on the appli-

cability and effectiveness of treatment by activated car-

bon and by hydrolysis’ EPA should have entertained a

new round of comments."

Certainly nothing is more important than the bottom

line numbers which determine whether individual plants

are or are not in compliance with the regulations. The

data that an agency has used to set proposed limits ob-

viously should be subject to public comment if possible.

Indeed, as another circuit court has noted, factual mat-

ters “are especially subject to verification through the

11Tt is ironic that petitioners should be attacking EPA’s use

of an expanded data base since a constant theme of their substantive

attack on the regulations has beei that EPA did not collect enough

data to support the regulations.

13a

notice and comment process and less acceptably removed

therefrom.” Weyerhaeuser, slip op. at 1030 n. 26.

This does not mean, however, that any new numbers

gathered after publication of proposed regulations must

be submitted for comment. It is perfectly predictable

that new data will come in during the comment period,

either submitted by the public with comments or collected

by the agency in a continuing effort to give the regula-

tions a more accurate foundation. The agency should be

encouraged to use such information in its final calcula-

tions without thereby risking the requirement of a new

comment period. Though in this instance the new in-

formation is in the form of numbers, our inquiry is

no different than where the new information takes any

other form. We must decide whether using new data

that reduced the effluent limits for many of the producers

deprived the public of a fair opportunity to present

views on the final data base. If data used and dis-

closed for the interim regulations presented the issues

for comment, then there is no need to seek new comment

even though significant quantitative differences result.

We conclude that EPA was within the law. The final

regulations set the pesticide discharge limit on the basis

of data from nine plants with recommended pesticide

removal technology. Seven of these nine plants were

mentioned in the interim development document as form-

ing the basis for or supporting the limits set by the

interim regulations.'"* These seven plants accounted for

about 82 per cent of the data points used to determine

the final limits. Their products, treatment systems, and

raw waste load were all discussed in detail in the interim

development document, as was what was known of the

12 One of these plants, able to meet the limits without all the

components of a recommended treatment system, was not explicitly

relied on in developing the interim limit, but was mentioned as

supporting the reasonableness of the limit set.

l4a

content of their waste water discharges. On the strength

of what was disclosed in the interim development docu-

ment, therefore, petitioners could have commented on

the applicability of these plants’ treatment systems to

other plants, and on the importance of different processes,

products, and volumes.

More importantly, the interim development document

disclosed the method by which EPA calculated the limits.

This methodology was substantially the same for the

interim and final regulations. EPA afforded petitioners

the chance to make the most meaningful possible con-

tribution to the regulatory process because the petition-

ers could use the information to collect data at their own

plants, analyze it, and submit it to EPA. Not only

would such input have guaranteed that EPA would be

acting on the most complete data base possible, but it

would have guaranteed that the special problems faced

by each petitioner would have been taken account of by

EPA and contributed to the resulting limitations.’* Peti-

tioners knew the role that every available piece of data

would play in generating the limits. EPA used all the

data supplied to it.

As to these seven plants, petitioners knew all they

needed to know in order to make a meaningful contribu-

tion to the regulatory process and a meaningful comment

on the regulations proposed. All they did not know was

what the actual raw numbers would be. While these

numbers were certainly crucial in setting the limits and

and of obviously great interest to the petitioners, we are

not convinced that knowing them would have significantly

improved petitioners’ opportunity to comment. They

13 The purpose of requiring notice is to generate responses as

well as to hold agencies to adequate procedures. Where petitioners

do not take advantage of chances to influence the agency we must

look with less favor on those petitioners’ allegations of inadequacy

in the result. See Weyerhaeuser, at 1028 n.15.

ae

15a

would have had a different numerical target for their

many complaints about the limits set, but that would

not have greatly advanced their ability to make positive

contributions to the process by criticizing from their own

knowledge the treatment technologies recommended, the

success they could anticipate by implementing those tech-

nologies, and the analytical and statistical methodology

EPA used to turn the raw numbers into effluent limits.

In short, in this case, we think it was far more important

for EPA to solicit comments on how it intended to col-

lect and use data than on the data itself."

Regulatory targets have no guarantee that proposed

effluent limits, which they are capable of meeting, will

stay the same. The purpose of soliciting comments is to

be able to make informed changes, and those interest

groups preferring looser limits are not the only ones

whose comments are solicited. Other governmental agen-

cies or public environmental protection groups are free

to seek whatever changes they feel desirable, and the

EPA is free to adopt those suggestions if it is persuaded.

As for the two plants that did not contribute to the

generation of the interim limits, the same arguments ap-

ply in part. All they added to the process were more

numbers to be used in the same way as the other num-

bers. Their treatment technologies are not markedly dif-

ferent from the others and conform to EPA’s fully dis-

closed model technology.*® Moreover, were these two

14 To help illustrate, we think it apparent that had EPA made a

serious arithmetical error in calculating the interim regulations

so that the effluent limits were higher than they should have been

if correctly figured, EPA would have been privileged to make the

correction between proposal and final promulgation without sub-

mitting the revision for new comment.

15 This case differs from Weyerhaeuser, at 1028-1031, because the

Agency’s final published explanation fully accounts for the limits

set. There are no undisclosed numbers or factors on which the

Agency must rely to support its final limits. See id. at 1030. The

same calculations on the same factors were used for both the interim

and final regulation, although the factors’ values varied.

l6a

plants omitted from considération the final limits would

be more stringent since both of these plants discharge

more than the allowable amount of pollutants.*®

B. EPA’s Scientific Methodology

The BASF petitioners have tenaciously at*acked the

methodology and data used by ESE in calculating the

final effluent limitations for organic pesticides. If ESE’s

work is not reliable, then the final limitations cannot

stand. Partly because of a belated turnover of some 2000

pages of laboratory documents—all of those used by ESE

for this rulemaking proceeding—we have been faced with

three rounds of briefing memoranda, dealing with targets

that were both moving and increasingly particularistic.

If we are not to lose our bearings in this extensive cross-

fire of chemical expertise, it is important for us to gain

and hold a perspective both as to facts and law.

ESE was retained in 1976, after EPA became dis-

satisfied with the work done over the prior two years by

another contractor. ESE thereafter collected data from

pesticide manufacturers and did its own experimentation

on samples of waste water, the manufacturers furnish-

ing 95 per cent of the data, and ESE laboratory work

accounting for 5 per cent. The methodology and resulting

data used by ESE to identify and quantify organic

pesticides relate to two techniques, gas chromatography

(GC) and thin layer chromatography (TLC). The

method attracting most of the controversy in this appeal

is gas chromatography. It involves vaporizing a sample

of effluent, passing it through a column filled with various

materials, which impeded the flow of each compound at

a characteristic rate. Results are recorded on a con-

16 Petitioners also complain about data from new plants being

used to generate the final BOD and COD limits, but this was evi-

dently because they misidentified one of the plants. In any case,

substantially the same plants supplied the data for both the interim

and final regulations.

tinuous chart which shows a “peak” when each compound

exits the column, thus identifying it in terms of the time

it appears, and which indicates concentration by the

height and area of the peak. The method is neither

simplistic nor self-executing. It involves the use of sev-

eral columns, the testing and calibrating of each with

samples containing known quantities of known pesticides,

continual checking, and constant alertness for the pres-

ence of unforeseen substances which can distort the re-

cording on the strip chart. The method succeeds only

in careful and expert hands.

The lore of gas chromatography has been recognized

for some time, being the subject of a handbook compiled

in 1972 by EPA’s Analytical Quality Control Laboratory

(and the source of ESE’s practices in this rulemaking

procedure), the “Analysis of Pesticide Residues .. .” in

1974 and “Analytical Procedures for Pesticides Approved

by EPA per 40 C.F.R. Part 136”, App. 1997-2090. These

compilations dealt with means of isolating interferences

(distorting effects occasioned by the presence of unidenti-

fied substances), the preparation of apparatus, calibra-

tion, reagents, solvents, standard quality control prac-

tices, the preparation of samples, extraction, clean-up,

and reporting. Part of the product of ESE’s work lay

in the development of a new handbook, the Quality As-

surance Manual, which was in revision at least through

September of 1977.

The factors underlying the present controversy as to

the methodology of identifying and measuring organic

pesticides are threefold: the complexity of the process,

the high degree of elimination of pollutants required by

the regulations, and the penalties for non-compliance.

83 U.S.C. § 1319. Petitioners point with dismay to the

analytical obstacles, pitfalls, and limitations which EPA

18a

acknowledges and warns against,'’ and challenge the re-

liability and adequacy of both GC and TLC. They fur-

ther document their dismay by criticizing ESE for lack

of an articulated quality control program; criticizing

specific instances of ESE’s work; noting the wide dis-

crepancies between analyses of the same samples by sev-

eral manufacturers and by ESE; and challenging the

inclusion of a requirement based on chemical oxygen

demand (COD) as not being feasible or useful.

The considerations governing our task of review in

such a case as this have been recently illumined in

Weyerhaeuser Co. v. Costle, at 1025, where Judge Mc-

Gowan, writing for the court, said:

“In light of the structure and aims of the Act,

and the breadth of authority delegated by it to the

EPA to identify highly sophisticated control tech-

nology in an area fraught with scientific uncer-

tainty, our review function encounters significant

limitations in the substantive aspect where the given

statutory standards are ‘arbitrary,’ ‘capricious,’ or

‘abuse of discretion.’ First, it is elementary that

our function is not to weigh de novo the available

17 The introductory material in “Analytical Procedures” describ-

ing the application of gas chromatography to organochlorine pesti-

cides contains such language as: “Under favorable circumstances,

Strobane, toxaphene, chlordane (tech.) and others may also be de-

termined”; “The usefulness of the method for other specific pesti-

cides must be demonstrated by the analyst before any attempt is

made to apply it to sample analysis”; when there are “complex

mixtures, the individual compounds may be difficult to distin-

guish .... Provisions incorporated in this method are intended to

minimize the occurrences of such interference”; “the method offers

several analytical alternatives, dependent on the analyst’s assess-

ment of the nature and extent of interferences and/or the com-

plexity of the pesticide mixtures found”; “This method is recom-

mended for use only by experienced pesticide analysts or under the

close supervision of such qualified persons”; “It is not possible to

describe procedures for overcoming all of the interferences that

may be encountered in industrial effluent.”

evidence and to substitute our judgment for that of

the Agency. Second, an expansive concept and ex-

ercise of the review power in the eleven Courts of

Appeals charged with that function could easily

impede accomplishment of the Act’s ambitious pol-

lution-ending aspiration as well as its goal of indus-

try-by-industry uniform*ty. See generally, Currie,

Judicial Review Under Federal Pollution Laws, 62

Iowa L.Rev. 1221, 1261-71 (1977). This problem

looms larger in the substantive area of review than

it does in those areas involving statutory interpreta-

tion and procedural integrity because of the tech-

nological and scientific uncertainty that EPA must

overcome as best it can in making the discretionary

judgments delegated to it by Congress. There are

also obvious limitations upon the capacity of courts

to deal meaningfully with arcane areas of knowl-

edge of this kind.”

After quoting from the court’s earlier opinion in Jndus-

trial Union Dep’t v. Hodgson, 162 U.S.App.D.C. 331,

338-39 n. 18, 499 F.2d 467, 474-75 n. 18 (1974) (“Where

existing methodology or research in a new area of regu-

lation is deficient, the agency necessarily enjoys a broad

discretion to attempt to formulate a solution to the best

of its ability on the basis of available information.”),

Judge McGowan summarized the court’s view of its

mission :

“In these circumstances, therefore, we will be con-

tent in carrying out our substantive review (that is,

assuming the statute and the requisite procedures

have been followed), first, to insist upon an explana-

tion of the facts and policy concerns relied on by the

Agency in making its decision; second, to see if those

facts have some basis in the record; and finally, to

decide whether those facts and those legislative con-

siderations by themselves could lead a reasonable

20a

person to make the judgment that the Agency has

made. See Citizens to Preserve Overton Park, Inc.

Weyerhaeuser, at 1026.

With these precepts in mind, we consider petitioners’

challenges.

The first is to the reliability and adequacy of the two

basic methods endorsed by EPA, gas chromatography and

thin layer chromatography. Petitioner’s general attack

is based, as we have noted in note 17, on the acknowl-

“ edged uncertainties attending the successful use of the

methods in dealing with complex mixtures. It seems to

us that EPA’s cautions are to be preferred by far to

overclaiming or overselling. It also seems to us that

action of this nature, although not without risk to manu-

facturers, is preferable to no action at all. We are

mindful of the fact that Congress contemplated a certain

amount of “technology forcing’, Weyerhaeuser, at 1057,

expecting EPA “to press sometimes beyond the most

advanced technology currently being used”. Jd. at 1061.

Here, there is no claim that the technology has not been

developed but merely that EPA has overstated its public

acceptance. If the issue were whether the American So-

ciety for Testing and Materials (ASTM) and the Ameri-

can Public Health Association (APHA) had approved GC

methods for testing all three classes of organic pesticides

for which EPA claims GC to be appropriate, EPA might

lose. But it seems clear to us, from the literature, in-

cluding the series of manuals and handbooks dealing with

both GC and TLC going back at least to 1972, and from

the fact that several EPA test methods for organic

pesticides have almost completed running the gamut of

(

2la

ASTM and APHA approval processes, that any a priori

attack on the methods must fail.

This leads us to more specific criticisms. The most

sweeping of these is petitioners’ claim that ESE, so far

as the record discloses, pursued no systematic and re-

liable quality control procedures in running its tests on

samples of effluent. In its initial form the argument was

that the many steps ** prescribed in the Chemistry Divi-

sion and Radiochemical Laboratory Quality Assurance

Manual, which ESE itself developed, were not followed.

EPA’s response, that this Manual was in preparation

during most of the time ESE was running its tests,

seems sufficient to us.’® Petitioners counter that whether

judged by the new Manual or the 1972 Handbook, ESE’s

procedures were nowhere described or approved by EPA.

This seems to be trve. Were the project for which ESE

was engaged that of applying standard technology to

routine operations, we might expect to find a pre-

established testing procedure. But here part of the task

was to find and develop the appropriate testing technol-

ogy, resulting in the new Quality Assurance Manual.

18 These included a complete description in final project reports

of methods used, a pre-established quality assurance plan for each

project, the use of quality control input sheets and instrument

log books, determination of maximum times for holding samples,

documentation of ways in which samples were selected, calibration

of instruments, frequent preparation of “linearity curves”, fre-

quent running of standards to keep track of changes on the per-

formance of the equipment, and routine checks through running a

blank (solvent extracted from distilled water) through the column,

conducting duplicate analyses of the same waste water sample, and

running “spiked” samples (waste water to which known quantities

of pesticides have been added).

19 Petitioners point out that tests of one manufacturer, Olin, were

not completed until after the Manual was fully revised. Their argu-

ment that failure of ESE to jettison its prior procedures and

follow the newly promulgated Manual in conducting the very last

tests on one plant’s samples constitutes adequate basis for remand

seems to us utterly unrealistic.

22a

ESE came on the scene after a prior contractor had

been found inadequate. It obviously had a mandate to

produce scientifically acceptable work; EPA had demon-

strated its reaction to inadequacy. Between late 1976

and the fall of 1977 ESE invested 16,500 man hours in

this rulemaking process. (App. 1491) As we have noted,

all of its working papers, totalling 2000 pages have been

turned over to petitioners. The specific criticisms we

shall later discuss are the total harvest of hindsight.

Most, we think, are answered satisfactorily by EPA;

some are ignored. We find ourselves, as a reviewing

court, dealing with adversaries who deal with the issues

on different levels. Petitioners have combed the record

to select what they deem to be errors or examples of

sloppy work. EPA, on the other hand, seems to have

adopted a rather bland approach, selecting only what it

views as important challenges, and giving them a min-

imum response.

The issue of ESE’s quality control standards offers

an example of these diverse approaches. Petitioners de-

ery the absence of a description of methods, quality con-

trol charts, the failure to prepare a “reproducible stand-

ard curve”, the failure to run an adequate number of

standards, an inadequate number of spiked and “method

blank” samples, and duplicate analyses insufficient in

quantity and quality. Their citations to the record are

few. EPA’s response to this range of criticism is largely

set forth in the following footnote language in its mem-

orandum responding to petitioners’ reply brief: “Com-

plaints of inadequate numbers of standard and spiked

samples are refuted by laboratory documents supplied

petitioners pursuant to the Court’s request at argument.”

We have therefore conducted our own review. It was

restricted to 238 pages of ESE documents (App. 3352-

3590). It was necessarily superficial, since we are not

laboratory technicians, since the function of the various

23a

forms and entries was often not self evident, and since

many of the forms were illegible, some were apparently

duplicates (App. 3469, 3470; 34138, 3556) or triplicates

(App. 3368, 3474, 3582), and a sizeable number were

upside down. We found frequent evidence that ESE

testing had involved the running of duplicates,*° stand-

ards,’ blanks,” and spiked samples.** Occasionally we

found apparently careful step-by-step instructions for

performing tests (App. 3352, 3505); notations that a

test was defective and ought to be repeated (App. 3476,

3502) ; remarks that samples had been lost (App. 3414,

3431) or that the recording pen had jiggled on several

chromatograms (App. 3412); and interpretive remarks

noted in December, 1978, apparently for use of petition-

ers (App. 3432, 3487-3489, 3491-3492, 3495). We have

also read ESE’s monthly progress reports to EPA and see

evidence of concern for careful procedure. (App. 1453,

1455, 1456, 1460, 1461).

We cannot be sure that these references are an ade-

quate response to criticisms levied at ESE’s general con-

trol procedures. But we cannot play the role of Super-

chemist.** Petitioners bear an extremely heavy burden

24 Here is an example of thrust and parry between chemists where

we are being asked to give the final answer.

Petitioners: ESE did not run duplicates for 4 or 5 plants

relied on. (Main brief, p. 46)

EPA: It did, at all 4, citing appendix references. (Main brief,

p. 56, n.64)

Petitioners: But for duplicate samples to provide quality con-

trol over extraction and clean-up techniques, the duplicate

24a

if they desire to demonstrate that the results of a rule-

making procedure are infected with fatal flaws of labora-

tory practice. Our review, partial and facial though it

is, satisfies us of the probability that EPA was justified

in basing its regulation on ESE’s work.

Our feeling is strengthened by our review of some of

the specific instances of alleged error in results charged

by petitioners. They have pointed to the wide diverg-

ence of the analyses conducted principally by manu-

facturers Rhom and Haas and Eli Lilly and those per-

formed by ESE on “split” samples of the same waste

water. ESE consistently found much higher quantities

of pesticide in the samples. As we have indicated above,

we have not found sufficient reason to reject ESE’s

analytical procedures or results. And, while the methods

generally used by the companies were sufficiently re-

liable,2* we know nothing of the procedures actually used

samples must be independently extracted, cleaned up, and in-

jected into the column. (Reply brief, p. 18)

EPA: But the samples were so laden with pesticide, that they

had to be preserved in chloroform; this meant that when a

sample container was opened, the whole sample would have to

be used immediately. Hence ESE could run only injection

duplicates. (Memorandum in response to petitioners’ reply

brief, p. 6)

Petitioners: No. The layering that might be induced by

chloroform could be avoided by mixing the sample just prior to

splitting. Moreover, the need to preserve the sample arose

because of ESE’s excessive delay. Also, ESE’s alleged method

does not provide for the use of chloroform. Also, the lab notes

say nothing about the need to shortcut making parallel extrac-

tions. (Memorandum in response to EPA memorandum, p. 4)

25 As EPA noted in 43 Fed.Reg. 17776, 17781 (1°78) :

“The analytical procedures utilized by each manufacturer

were sclicited by EPA and evaluated by the Environmental

Monitoring and Support Laboratory in Cincinnati. The data

utilized in establishing these limitations were derived from

analytical methods which, in the opinion of the Cincinnati

Laboratory, ‘appear capable of measuring the compound with

adequate sensitivity.’ ”

by the companies in taking and preserving these samples.

We therefore cannot say that the divergence of results

indicates error on the part of ESE. Moreover, of course,

rejection of the lower figures is to the ultimate advantage

of the companies, increasing the allowable discharge.

Petitioners also focused on what first appeared to

them as a “patent error” in ESE’s calculations of the

amount of waste water used in a test, amounting to more

than a 55 gallon drum. But this turned out to be cor-

rect, EPA saying that the sample was so polluted that

it had to be diluted 250,000 times. Petitioners noted two

strip charts for sample 9010, speculating that a “shoul-

der” indicated interference and that a peak which ran

off the paper could not be only 3.6 centimeters high. But

EPA counters by saying the first peak was so pesticide-

laden that it did indeed run off the paper, but that the

rerun was indeed 3.6 centimeters high. The supposed

interference denoted by the shoulder was the occasion for

the technician’s comment we have noted concerning the

jiggling of the recorder pen. App. 3412. Other charges

were that two strip charts supposedly representing dupli-

cate analysis were not “remotely comparable’—the re-

sponse being that they were successive analyses with the

differences due to the large amount of pesticide present

in the ‘early extractions; that ESE improperly used

higher influent numbers ascertained by a Perkin-Elmer

instrument with no explanation for rejecting the lower

numbers obtained by a Varian instrument—the reply

being that each instrument is more effective in different

ranges of numbers. Although petitioners have a retort

in each such instance, we must say that EPA clearly has

the better of these arguments.

There are other even more minor issues where we

confess that we are not sure of the winner—whether as

to a particular analysis, a standard strip chart should

have been verified, whether ESE’s injections were too

26a

little in volume, whether the lack of confirmatory tests

on alternate columns of different polarity was significant.

As to these and other issues, EPA either did not respond

or did not do so at sufficient length to be understandable.

But we have said enough to indicate that residual doubt

on issues of increasing minuteness is far from sufficient

to cause us to interpose a different judgment than that

exercised by the Agency in choosing to rely on its con-

tractor.

Petitioners have raised one additional issue of a sub-

stantive technical nature in challenging EPA’s choice

of COD as a parameter. The contention is that it serves

no purpose where wastes possessing large amounts of

salts are to be dealt with. Diamond Shamrock’s data are

said to be of doubtful validity. But without such data,

leaving only that developed by Monsanto’s Muscatine and

Anniston plants, the standard would be even more strin-

gent. Wholly apart from absence of prejudice, EPA

points to the wide use of COD in industry as a measure

of long term biochemical oxygen demand and a com-

ment from Olin that “[I]t is a mystery why the Agency

feels compelled to establish a limitation on BOD when

COD measurements are more feasible.” C.App. 212.7¢

We cannot, in the words of the court in Weyerhaeuser,

slip op. at 23, say that “a reasonable person [could not]

make the judgment that the Agency has made.”

C. EPA’s Determination of Best Practicable Control

Technology Currently Available

Even accepting the work of ESE as accurate, peti-

tioners argue that the results do not support EPA’s

conclusion that carbon adsorption and hydrolysis are ef-

fective technologies for pre-treating pesticide waste

streams to remove organic pesticide chemicals. Closely

26 References to the confidential portion of the appendix will be to

“C.App.”.

27a

related to this challenge are the arguments that the num-

bers with which EPA calculated the final effluent limits

were inaccurate, thus invalidating those limits, and that

EPA could not reasonably combine all manufacturers of

organic pesticides into one category required to meet

the same limits. EPA’s decision that by using the model

technology, including either carbon adsorption or hydrol-

ysis, all plants achieved “similar” pesticide content in

their effluent led EPA to conclude “that the waste waters

of all organic pesticide chemicals can be treated or con-

trolled to the levels documented in the Agency’s data

base.” 43 Fed. Reg. 17777 (1978).

In carbon adsorption, the organic molecules reach the

surface of the carbon where they diffuse into the car-

bon’s porous structure and bind with the carbon. The

molecular structure and solubility of the pesticide in-

fluence its adsorption characteristics. Periodically the

carbon becomes saturated and requires regeneration

which can be accomplished by incineration. The result-

ing flue gases are quenched, scrubbed, and discharged

to the atmosphere. The carbon can then be reused, al-

though its adsorptive capacity will be somewhat reduced.

Hydrolysis is a chemical process in which the pesticide

compounds are broken down by adding a caustic (or an

acid) to the waste water setting off a reaction with the

water and the organic compounds. The hydroxyl or hy-

drogen ions attach to some part of the pesticide chemical

molecule, either displacing part of the group or breaking

a bond so that two or more new compounds form. The

suecess of hydrolysis is a function of the temperature

and pH (relative acidity or alkalinity) of the solution

and the properties of the chemical. Some compounds

hydrolyze relatively easily compared to others. The ability

of a compound to be hydrolyzed can be measured in terms

of the half-life of the reaction, the time it takes at a

given temperature and pH to hydrolyze half the chemical

28a

present. The shorter the half-life, the easier it is to de-

stroy the pesticide through hydrolysis.

The regulations do not require the use of any par-

ticular treatment technology so long as the effluent

limitations are met. One of the premises of the regula-

tions, however, is that by using either carbon adsorption

or hydrolysis, together with equalization and biological

treatment, any plant could meet the regulations. Pe-

titioners argue that there is no basis for this conclusion

and that, therefore, we should remand the regulations

as to the organic pesticides category. They suggest that

the data collected at operating facilities are unrepresenta-

tive, inaccurate, and insufficient to demonstrate that those

facilities achieve the results EPA claims; that even if

those facilities do achieve the results claimed there is no

data to suggest other plants producing other pesticides

could achieve comparable results; and that EPA’s ref-

erences to literature and pilot studies fail to support

its conclusion.

We emphasize again that our review of agency rule-

making is very limited, especially where the Agency

must overcome technological and scientific uncertainty

in making its delegated discretionary decisions. See

Weyerhaeuser, at 1025. We will not remand so long as

the Agency has explained the facts and policies on which

it relied; the facts have some basis in the record; and

a reasonable person could make the judgment the Agency

made. Jd. at 1026. Thus, the petitioners carry an ex-

tremely heavy burden when petitioning for review in

such a case as this.

EPA identified eight full-scale carbon treatment sys-

tems used to reduce pesticides and five full-scale hydrol-

ysis systems. The Agency sought information on all these

facilities. One of the plants using carbon adsorption (one

of the petitioners before us) disclosed neither the operat-

ing conditions of the system nor individual analyses of

¥

29a

its effectiveness. Information on the remaining 12 sys-

tems is presented in great detail in section VII of the

Development Document. Five of the seven carbon sys-

tems achieve removal rates in excess of 99 per cent of

the influent pesticide as do two of the three hydrolysis

systems for which data is available as to the pesticide

content of both the influent and effluent of the treatment

system. The two hydrolysis systems, for which only

effluent data is available reduced the pesticide level to

less than 1 mg/1 (one part per million) and to below

the detection point respectively. EPA has concluded that

the two substandard carbon systems and one sub-stand-

ard hydrolysis system could all achieve much better re-

sults by adjusting the operating conditions of the fa-

cilities (replacing the carbon more often or holding the

waste water in the treatment system for a longer period).

Petitioners attack the use of data from the carbon

systems because the systems were not designed to re-

move pesticides. This attack is trivial. EPA faces a

severe problem in regulating the pesticide industry be-

cause a great deal is not known about treatment of

pesticide waste waters and because the industry is very

reticent about revealing what it does (or could) know.

Given this admitted information shortage EPA must

make use of the information it has, recognizing the limits

of the information; EPA cannot refuse to carry out its

mandate, waiting for the day when it might possess

perfect information.** Whatever reasons industry might

27 By the same token, petitioners’ broadbased attack on EPA’s

use of data in literature must be rejected out of hand. Certainly

the literature data are not as valuable as operating plant data

would be, but the plants have not supplied enough information, and

the literature is useful for what it does say. For instance, if the

literature identifies a particular pesticide as amenable to treatment

by adsorption or hydrolysis under laboratory conditions, that does

not guarantee the same results under industrial conditions, but

neither does that mean the information should be ignored. It means

that, other things being equal, the pesticides can be treated. It is

have had for installing carbon treatment systems, if those

systems are effective at removing pesticides then EPA

can and should make use of that information. The alter-

native would be to ignore the mandate of the Federal

Water Pollution Control Act and allow the pesticide in-

dustry to develop treatment systems at its own pace,

releasing information about those systems only for the

purposes and under the conditions the industry might see

fit. Congress has rejected that alternative.

The same answer applies to petitioners’ claim that

the data on carbon treatment systems were too sparse to

support any conclusion about their effectiveness. EPA

had no more than 25 observations at any given facility

and as few as 4 observations at another. EPA used all

the data it could accumulate. Had the industry come

forward with more data there is every indication that

EPA would have used it. Data on the performance of

the treatment systems are entirely within the control

of the industry. We will not hear industry complain

that EPA used insufficient data when industry was un-

cooperative in supplying the missing data. It was up

to EPA to decide whether the limited data base was suf-

ficient to support the conclusions reached. We hold that

deciding to base conclusions on the limited data available

was a reasonable exercise of discretion given the regula-

tory mandate.*®

then up to the Agency experts to decide whether relaxing the labora-

tory conditions would so change the result that the pesticide

could not be treated by industry. Merely attacking the literature

because it is experimental is no help to petitioners’ cause unless

they can also show that the particular conclusions drawn from the

literature are unreasonable. We have found nothing in the Act to

Petitioners suggest that even the limited data avail-

able at three of the carbon treatment plants are unrep-

resentative because the data were collected too soon after

replacement of the carbon columns or because some

wastes bypassed the treatment system being studied. The

sampling at Eli Lilly covered the first 4 days of a 7 day

carbon cycle. The record does not reveal why the carbon

was changed just before sampling began or whether

either ESE or Lilly timed the change purposely. The

data, however, covered more than half the cycle, and

the record reveals that the results obtained during the

ESE sampling period were, if anything, unrepresenta-

tive on the high side since they showed a higher con-

centration of pesticide in the treatment effluent than the

company found in its own studies. C.App. 217. The

sampling at Hardwicke was done early in that company’s

normal 30 day carbon cycle, but, as EPA noted, the car-

bon should be changed far more frequently and the

sampling was fairly representative of what would have

been a reasonable carbon cycle for the plant.

Petitioners also argue that Lilly and Olin generated

waste streams containing pesticides that did not pass

through the treatment systems. Their citations with re-

gard to Lilly are unconvincing. The direct communica-

tion from Lilly says nothing about a pesticide-bearing

waste stream by-passing carbon treatment. The MITRE

study does not support the claim. It says that the only

two waste sources containing the pesticide may be com-

bined prior to treatment. C.App. 206. We find no in-

dication that the “Floor drains, Cooling Waters, and

Miscellaneous Waste Streams” contained any pesticide.

C.App. 207.

The problem with respect to Olin is not so easily dis-

posed of. On March 15, 1977, Olin submitted its com-

ments on the interim final regulations. It stated that

EPA’s data omitted “supplementary waste streams con-

¢

32a

taining some process wastewaters.” C.App. 213A. An

attachment to these comments described the supplemen-

tary waste streams as including “among other things,

spills, wash-downs, vent scrubber effluents, and surface

runoff. In this wastestream, the following waste by-

product streams are not included: 1. PCNB Plant Hy-

drochloric Acid; 2. PCNB Plant Spent Sulfuric Acid; 3.

TCAN Plant Hydrochloric Acid.” C.App. 218A. Finally,

this letter stated as “basically an intelligent guess” that

1.3 pounds of pesticide were in the supplementary waste

stream (not including “TCAN, HCL, PCNB HCL and

PCNB spent nitration acid.”). EPA visited Olin’s plant

on August 17, 1977. According to a memorandum of that

visit, “[p]lant personnel were unable to provide back-up

information supporting the revised waste load estimates

reported to EPA in a letter from Olin dated March 15,

1977. They argeed to provide the basis of these revised

waste loads upon receipt of a letter from EPA.” C.App.

304. On August 18, 1977, EPA sent a letter to Olin

seeking, inter alia, more information about the supple-

mentary waste streams; confirmation that “these supple-

mentary waste streams have not been, and are not cur-

rently being treated by activated carbon, but rather are

neutralized and discharged”; and confirmation that the

existing “waste byproduct streams” (the acid streams)

were being reused or sold. App. 2625-26. Olin answered

by letter of September 14 that it had no additional data

on raw waste load (other than some flow rate data) ;

that “[t]he supplementary waste streams associated with

the PCNB Plant are currently only being neutralized” ;

and that “(t]he information you have outlined for the

current disposition of the three by-product acid streams

is correct.” C.App. 352-53.

EPA’s response to petitioners’ argument is that “[t]he

truth as acknowledged by Olin, is that there are no

[unaccounted for] streams.” EPA brief at 62. EPA’s

brief-writers misread the exchange quoted above. They

33a

interpreted Olin’s acknowledgement that the three acid

by-product streams were not being discharged as mean-

ing that no supplementary waste streams were being

discharged. A clear distinction was made at all times in

the exchange of correspondence between the acid “by-

product waste streams” and the pesticide-bearing supple-

mentary waste stream. The latter is clearly the one of

concern, and Olin clearly stated that it was being dis-

charged with no treatment other than neutralization.

The implication is that Olin was discharging more

pounds of pesticide per thousand pounds of production

than the figure EPA used in calculating the limits, and,

therefore, the limits were miscalculated and should be

corrected.” The treatment given the issue in EPA’s

brief leaves us uncertain how to handle it. On the one

hand, we might be inclined to discount an “intelligent

guess” about extra pesticide when no supportive data is

forthcoming despite the Agency’s follow up efforts. On

the other hand, though, EPA has not explained the basis

for ignoring the new information, and EPA’s brief deals

with it on an inaccurate basis.*° Under these circum-

stances we feel compelled to remand the regulations for

consideration of petitioners’ claim that the Olin data

should not be used in calcualting the final effluent limits. .

It may be that EPA can easily correct any defect, but

we must put them to the task.

Similar arguments are directed against plants EPA

used to illustrate hydrolysis treatment. Petitioners ob-

29 This confusion cannot impugn the conclusion that Olin’s carbon

adsorption system effectively treats the waste streams that in fact

pass through it.

30 The brief-writers compound the inaccuracy (and diminish our

trust in them) by arguing that the 1.3 pound figure must be dis-

believed because it disagrees with data submitted by Olin on Sep-

tember 14, 1977. C.App. 353. That data only concerned the influent

and effluent of the carbon adsorption system. The 1.3 pound

figure related to waste not passing through the system.

84a

ject to reliance on two plants claiming that in fact neither

has an hydrolysis system. In fact the record reveals

that both plants hydrolyze the wastes, albeit not in sepa-

rate hydrolysis basins. Kerr-McGee adds a caustic to

elevate the pH above 11 and elevates the temperature to

facilitate the reaction. App. 991. Monsanto’s Anniston

plant similarly sets off a reaction with addition of caustic

to raise the pH, App. 2459, though the temperature is

not raised. App. 126-27. In effect, hydrolysis and bio-

logical treatment occur simultaneously. Although there

may be some problem in attributing the destruction of

the pesticide to one or the other cause, both treatments

are recommended, and the success of these systems is

relevant to whether companies can meet the guideline

limits ** and supports the conclusion that hydrolysis is

being used successfully in the industry. The same holds

true for Shell’s Axis plant. Though there is no influent

data, the effluent data indicates that with the hydrolysis

system the discharge of pesticide can be reduced below

the detection point.

Petitioners argue that even the plants for which EPA

has operating data are far from “similar” since, for in-

stance, their pesticide output varies between 0.0000765

and 0.00315 kg/kkg. This is indeed a rather broad range,

but it does not disturb us. The Act imposes no obligation

on EPA to subdivide industries so that each point-source

category contains identical producers. The development

document reveals that EPA carefully thought about the

31 Petitioners also object to use of data from Hercules to calculate

the effluent limits. Hercules uses neither hydrolsis nor carbon ad-

sorption to treat its waste water. It achieves excellent results with

a physical-chemical system relying on equalization ponds, gravity

separation, and neutralization. Though it does not support the

proposition that hydrolysis and carbon adsorption are commor:

industry techniques, it is evidence of the levels to which pesticides

can be reduced by treatment. There is no reason to ignore these

results simply because they are achieved more easily than by use of

the recommended model technology. ,

35a

relevant factors when it divided the pesticide industry in-

to three categories. App. 57-61. It had tried to subdivide

the organic pesticides into three subcategories, and that

attempt was shown to fail. In fact, as we have noted,

industry commenters demonstrated that those three sub-

categories were indistinguishable from each other and

that that subcategorization scheme was inequitable. After

further study EPA concluded that there was no reason

to use subcategories at all. The advantages would be

negligible since there were no clear dividing lines between

groups of manufacturers, and the disadvantages, as

pointed out by the industry, were significant. Under the

circumstances we cannot say it was unreasonable for

EPA to reject industry’s advice that the fewer than 30

direct dischargers of organic pesticides be divided into

more than one category. Certainly we see no congres-

sional mandate that this industry be further subcate-

gorized.

Having decided to use a single category, EPA had to

set the limits for it. Its decision to use only data from

full-scale operating systems and to ignore zero-discharge

plants was well within its discretion. Thus it needed a

way to express the limitation more precisely than a re-

quirement such as that all plants “do as well as the

plants we have surveyed’. It needed to express the results

of the survey data as a number typical of the model

group—that is, an average. Averaging the effluent data

from the model plants is very different from averaging

apples and oranges or bananas and marshmallows. If the

plants performed identically, no average would be neces-

sary. Though the plants performed differently, even very

differently, we cannot see why averaging is unacceptable.

The same parameter was measured in the same way and

in the same units. The set of observations thus derived

made up the population of which an average was desired.

36a

The problem, as we see it, was not whether an average

could be taken, but how to derive that average.”

EPA chose to calculate a weighted average that gave

equal influence to each observation rather than to each

plant. Thus the plant with 4 observations had far less

influence on the final average that the plant with 450

observations, but each observation at the two plants had

exactly the same influence. We are sure there were many

alternatives to this system, but we cannot say that EPA

went beyond its discretion in picking this one. We agree

with the Fourth Circuit that “the choice of statistical

methods is a matter best left to the sound discretion of

the Administrator.” FMC Corp. v. Train, 5389 F.2d 973,

986 (4th Cir. 1976); American Petroleum Institute v.

EPA, 540 F.2d 1028, 1035 (10th Cir. 1976). The choice

of any given method may mean that an alternative method

would yield different results. The necessary corollary,

however, is that any other system chosen would be open

to the same criticism. We will not leave the Agency so

vulnerable.

Even if the plants studied demonstrate that carbon or

hydrolysis treatment is effective for the pesticides they

produce, petitioners point out that they produce only a

small minority of the 49 pesticides whose discharge is

controlled. This is true, but it hardly means that the reg-

ulations must be limited to those pesticides for which

EPA has collected information on operating treatment

systems or even to the larger group of pesticides cur-

rently being treated by adsorption or hydroylsis.* There

is literature data which suggests that other pesticides

are amenable to treatment. See note 27, supra. Also, the

Agency is entitled to use its chemical expertise to con-

32 The statistical methodology used in the interim regulations

was fully disclosed and was the subject of extensive comment. In

response to those comments EPA revised its methodology.

83 The industry failed to supply data on some operating systems.

87a

clude that compounds’ manufacturing processes, chemical

structures, and physical properties are sufficiently related

so that if one is treatable the others are likely to be as

well. Certainty is not required. It is enough that the

EPA has considered the problem and that the petitioners

have f<‘led to convince us that the conclusion is unrea-

sonable.** Petitioners have presented no evidence that

any particular regulated pesticide is not amenable to

treatment. Moreover, we assume that if any plant had

evidence that an adequate, properly run treatment fa-

cility corresponding to EPA’s recommendations could not

achieve the guideline limits, the plant would have a strong

case that it is “fundamentally different” and entitled to

less stringent limitations. 40 C.F.R. § 455.22, 43 Fed.Reg.

17780 (1978). We conclude, with the one reservation ex-

pressed above, that the Agency has demonstrated that

hydrolysis and carbon adsorption are currently used, ef-

fective pesticide treatment techniques; that the Agency

permissibly decided that the techniques are broadly applic-

able to facilities manufacturing the 49 pesticides dis-

charge of which is regulated; and that it was within the

Agency’s authority to require all manufacturers of or-

ganic, non-metallo pesticides to meet the same effluent

limitations.

34 By a combination of these sources and extensions of informa-

tion, EPA explicitly reached conclusions as to all but 10 of the

49 pesticides. App. 111, 113, 118-119, 126, 128-131, 132, and 138.

The ten of which we find no mention are BHC, Dichloran, Mirex,

Barban, Fenuron, Fenuron TCA, Swep, Dicamba, Silvex, and Per-

thane. We are willing to assume from EPA’s general language that

it reached similar conclusions as to these ten pesticides as well.

85 There is every indication that EPA was fully aware of the

various factors that, as petitioners point out, can affect the relative

amenability to *reatment of different pesticides. The development

document mentions them. See, e.g., App. 104, 110, 120. We will not

assume that the Agency failed to take account of such factors when

it evaluated the possibility of extending the recommended treat-

ment techniques to other chemicals.

38a

D. EPA’s Consideration -of Cost.

The Act requires EPA’s assessment of best practicable

control technology currently available to “include consid-

eration of the total cost of application of technology in

relation to the effluent reduction benefits to be achieved.”

33 U.S.C. § 1314(b) (1) (B). Cost, however, is not a para-

mount consideration. Congress “self-consciously made the

legislative determination that the health and safety gains

that achievement of the Act’s aspirations would bring

to future generations will in some cases outweigh the

economic dislocation it causes to the present generation.”

Weyerhaeuser, at 1037. The obligation the Act imposes

on EPA is only to perform a limited cost-benefit balanc-

ing to make sure that costs are not “wholly out of pro-

portion” to the benefits achieved. A Legislative History of

the Water Pollution Control Act Amendments of 1972

170 (1973) (statement of Senator Muskie); Weyer-

haeuser, at 1045 n. 52. Thus, the balancing is a rela-

tively subsidiary task and need not be precise.** Weyer-

haeuser, at 1049. The Agency has considerable discre-

tion to decide how to go about considering costs and

benefits and need not “perform the elaborate task of cal-

culating incremental balances” of marginal costs and

benefits.** Id.

36 We are not convinced that the duty to “include consideration

of cost in relation to benefit” imposed on EPA by this clause of

§ 1314(b)(1)(B) is significantly different from the duty imposed by

the same subsection to “take into account” certain other factors.

But see Weyerhauser, at 1045-1046. We see no more reason for us

to substitute our judgment for the EPA’s concerning costs and

benefits, assuming that the Agency has “informed itself as to their

magnitude, and reached its own express and considered [opinion]”,

see id., than concerning the other enumerated factors.

37 We agree with the Weyerhaeuser court that “when an in-

cremental analysis has been performed by industry and submitted

to EPA, it is worthy of scrutiny by the Agency.” At 1048. duPont’s

study, indicating rapidly increasing costs for removal of incremental

amounts of pollutants, certainly was “worthy of scrutiny”, and we

assume that EPA did not ignore it. Largely through no fault of

39a

We are satisfied that EPA has done an acceptable job

in this case. Facing a highly diverse industry, and strug-

gling with an admitted dearth of information (for which

—not without some justification—it blames the industry),

EPA sought to determine on a plant-by-plant basis the

capital and operating costs each plant would incur in

meeting the effluent limits. EPA found only seven direct

dischargers that would incur additional costs.** Of these,

EPA predicted five faced increased annual costs equal

to only 0.2 to 2.0 per cent of revenues from pesticide

chemicals and would not change employment or produc-

tion. A comparable estimate could not be made for one

other, and the last one would face costs of 3.6 per cent of

revenues. EPA concluded that the latter two might ex-

perience reduced profitability but would continue in pro-

duction. Capital costs were expected to total $9.9 million

and annual costs $5.1 million for the industry. 43 Fed.

Reg. 17777-78 (1978).

The Agency based these estimates on model treatment

techniques assuming a variety of plant sizes and treat-

ment difficulties. The petitioners criticize the estimates

and their application to plants on a variety of grounds.

Though many of the criticisms may be valid, suggesting

that the estimates are not perfectly accurate, none of

duPont’s, however, the study tested a carbon adsorption model

very different from the one that formed the basis for EPA’s cost

estimates. Most notably duPont studied contact times of 22, 44,

and 66 minutes whereas EPA prepared cost estimates for systems

with contact times of 60, 300, 600, and 750 minutes. Generally the

longer the effluent remains in contact with the carbon, the more

efficient the treatment will be. We are not prepared to say that the

duPont study demonstrates that incremental costs of EPA’s model

system were wholly out of proportion to incremental benefits, nor

will we require EPA explicitly to respond to every study submitted

by commenters.

88 EPA lacked information as to two others. The Agency, in a

permissible exercise of discretion, did not consider costs already

incurred in complying with NPDES discharge permits. Weyer-

haeuser, at 1049.

40a

them convince us that EPA’s evaluation of costs must

be rejected. There is no way the cost analysis could be

more than an estimate, especially given the reticence of

the industry to supply information, and EPA needed to

develop no more than a rough idea of the costs the in-

dustry would incur. On the basis of its estimates, EPA

decided to promulgate these regulations. We cannot say

that the Agency has failed to consider costs in relation

to benefits, and we find no basis on which to overrule

EPA and decide that costs are wholly out of proportion

to benefits.

II. Metallo-Organic Pesticide Manufacturing

Subpart B of the regulations is “applicable to dis-

charges resulting from the manufacture of metallo-

organic active ingredients containing mercury, cadmium,

arsenic, or copper.” 40 C.F.R. § 455.30; 43 Fed.Reg.

17786-87 (1978).* The regulations forbid any discharge

of process waste water pollutants to navigable waters.

40 C.F.R. § 455.32. The only challenge is from one of the

three manufacturers of arsenic-based pesticides, Diamond

Shamrock. Diamond Shamrock alleges that its process re-

quires it to discharge arsenic contaminated waste water

and that the record fails to support EPA’s conclusion that

a process with no discharge is the best practicable con-

trol technology currently available.

Diamond Shamrock has twice in the past reported that

its arsenic manufacturing process had no discharge of

polluted waste water. In August, 1975, it reported to

EPA that its “process has a negative water balance [and

is] able to utilize essentially all, including rainwater from

the process area, in the product.” A 1972 report stated,

“The arsenical unit has no discharge—its design is such

39 “ ‘Metallo-organic active ingredients’ means carbon containing

active ingredients containing one or more metallic atoms in the

structure.” 40 C.F.R. § 455.31(a).

4la

as to recycle all waters into the final product.” Other

reports, however, are either ambiguous or assert that

Diamond Shamrock in fact discharges contaminated waste

water. A 1974 study reported, “Diamond Shamrock’s

plant is a ‘low effluent’ plant, although they do discharge

aqueous waste. ... [T]he discharge of arsenic averages

about 0.7-0.8 [parts per million]. ... The total amount

of arsenic discharged amounts to only about 14 lb per

day.” *° In July and August, 1977, Diamond Shamrock

told EPA and ESE during a meeting and during an in-

spection of the plant that it discharged waste water and

could not meet the limit in the interim regulations. Data

covering January through May of 1977 show that there

is arsenic in the waste water discharged from the arsenic

process to the biological treatment facility and in the

discharge from the treatment facility. Flow charts de-

scribing Diamond Shamrock’s production process show

that waste water can be recycled, but suggest that some is

not. Finally, ESE’s notes of an April 26, 1976, telephone

conversation between an ESE researcher and a Diamond

Shamrock plant manager reveal that the plant manager

admitted that arsenate production has no waste but also

said the plant could not meet a limit of 0.1 parts per

million.*?

Though the record is far from clear, it indicates to us

that, while Diamond Shamrock may once have been a non-

discharger, at least as of the time these regulations were

40 This study apparently formed the basis for a 1975 EPA report

which, however, made a most critical error in transcription. It

said, “Diamond Shamrock’s plant is a ‘low effluent’ plant, although

aqueous waste is not discharged. . . . [T]he discharge of arsenic

averages about 0.7 to 0.8 [parts per million]. The total amount of

arsenic discharged amounts to only about 1% lb/day.” (Emphasis

added.) The internal inconsistency is obvious.

41 Diamond Shamrock’s comments on the interim development

document expressed concern about the zero discharge limit, but on

the ground that there is a higher permissible level for arsenic in

public water supplies.

42a

promulgated the plant was discharging pollutants and

had so advised EPA. This does not, however, end the

inquiry. The fact remains that the other eight manu-

facturers in the metallo-organic subpart, including the

two other producers of arsenic pesticides, achieve zero

discharge and have not joined the petition for review,*”

and Diamond Shamrock held itself out as a non-discharger

on some occasions.

Diamond Shamrock’s attempts to refute EPA’s evi-

dence concerning the other plants are unpersuasive. The

evidence consists of notes of phone conversations between

ESE and officials at the other two arsenic plants, Vine-

land and Ansul. According to the notes, Vineland’s chief

chemist claimed all waste water is recycled to the process,

and the Ansul official said, “All wastewater from the

pesticide production is reused in the process; the only dis-

charge is of non-contaminated cooling water.” Though

transcribed notes of phone calls are not the best possible

evidence, it seems that EPA confronted stern industry

resistance in its attempts to put together a more reliable

data base. Industry cannot be allowed to profit from the

success of its resistance to regulatory inspections. More-

over, in proceedings such as these EPA has to be able

to rely on industry-supplied information, especially where

dishonesty would be counter-productive for the informants.

It appears that the industry can and does produce

arsenic-based pesticides without discharging polluted

waste water. The statute, though, requires more; EPA

must consider specific factors including “the total cost

of application of technology in relation to the effluent re-

duction benefits to be achieved ..., and... the process

employed, the engineering aspects of the application of

various types of control techniques, process changes, [and]

42One of the other arsenic producers, Ansul, has apparently

ceased production. Its performance while in operation, however, is

relevant in determining achievable discharge limitations.

43a

non-water quality environmental impact .. .” 33 U.S.C.

§ 1314(b) (1) (B). EPA’s excuse for not considering these

factors is that Diamond Shamrock does not now, or at

least did not in the past, discharge polluted waste water,

therefore it would not have to change its process or incur

any costs in meeting the regulations.”

The record as we construe it does not support EPA’s

reasoning. Diamond Shamrock is now a discharger. it

will have to change something, whether in its production

process or its treatment process, in order to meet the

regulation. EPA must give some consideration to the

cost and impact, if any, of implementing these changes

and compare the cost to the reduction benefits. Until it

has performed that task, EPA has not discharged its

statutory responsibilities. Having failed to consider the

relevant factors, EPA abused its discretion, and we must

remand.

As indicated in our discussion of the required cost

analysis above, the consideration may be general, and EPA

has considerable discretion to determine the scope of the

investigation. We also emphasize that our remand on

this issue is a limited one to give EPA an opportunity

to perform the statutorily mandated assignment. If EPA

discovers that in fact Diamond Shamrock will not incur

costs or that the benefits of the regulation are not wholly

out of proportion to the costs to the industry, then we will

be prepared to uphold the regulations as written.

43 The Development Document reports as follows:

“No cost estimates have been developed for this subcategory.

The state-of-the-art at plants manufacturing metallo-organic

pesticide chemicals is no discharge of process waste water

pollutants. It was originally reported that all plants were no

‘discharge’ facilities, however, representatives of one facility

(plant 19) recently indicated that there is a discharge from

their manufacture of metallic-organo pesticide chemicals. This

is being investigated by the Agency. The overall.impact to this

subcategory is expected to be minimal.” App. 166.

EPA now advises us that there is not any ongoing investigation.

44a

III. Formulators and Packagers Subcategory

Subpart C of the regulations apply to formulators and

packagers of pesticides. 40 C.F.R. §§ 455.40-455.42. This

segment of the industry, encompassing approximately

5300 companies, mixes technical grade pesticide chemi-

cals with inert ingredients by dry-based, solvent-based, or

liquid-based processes to produce usable commercial prod-

ucts. These companies are required to release “no dis-

charge of process waste water pollutants to navigable

waters”. 40 C.F.R. § 455.42. EPA expects them to

meet this limit by a combination of in-process controls

and collection and evaporation of whatever waste water

cannot be avoided. NACA, on behalf of the formulators

and packagers, has intervened in these petitions for re-

view to challenge the no discharge limitation on a number

of grounds. NACA argues that EPA’s data base is so

inconsistent, inaccurate, and incomplete that it cannot

support any conclusion and that even taking the data base

at face value it does not support the conclusion EPA has

reached. Further, NACA argues that EPA has failed

to meet the statutory mandate to consider certain factors.

33 U.S.C § 13814(b) (1) (B).

We agree with NACA that EPA’s treatment of this

industry segment is not a model of administrative regula-

tory methodology, but, nonetheless, we find sufficient re-

liable data in the record to support EPA’s conclusion that

zero discharge is the best practicable control technology

currently available for this category. We rest this con-

clusion on two sources of data with respect to the reli-

ability and value of which EPA and NACA nearly

agree.“* The first of these is a telephone survey con-

44 EPA also relied on an “Economic Analysis of Effluent Limita-

tions Guidelines for the Pesticide Chemicals Manufacturing Point

Source Category”, a 1975 report entitled “Pollution Control Tech-

nology for Pesticide Formulators and Packagers” together with the

telephone survey on which it was in part based, and a study of one

company with 38 facilities. There is no suggestion that these

stale. , 4

45a

ducted by ESE. ESE polled, at random, a segment of

the industry,** and compiled 47 responses.** Of these 47,

only 8 discharge process waste water pollutants into

navigable waters. Another 8 discharge waste water to

privately operated treatment facilities, but such discharges

would not run afoul of these regulations.‘ Thus, 94 per

cent of the companies currently can comply with these

regulations, and 77 per cent are not discharging any

process waste water at all.

These results are confirmed by the second source, a

report compiled by a contractor hired by NACA and sub-

mitted to EPA by NACA. The report’s conclusions in-

cluded the following:

—“Some plants are currently operating with no dis-

charge of process waste water. By conservative water

usage and improved housekeeping practices, most

plants can either eliminate or significantly reduce the

volume of process waste water generated.”

studies conflict with the two we will discuss; rather, NACA argues

that they are unreliable, irrelevant, or not applicable to all

companies.

45 The exact number of firms contacted is not clear from the

record before us which reveals only the firms which responded to the

survey. It may be that this distinction between contacts and re-

sponses accounts for the confusion reported in note 46, infra. NACA

has not challenged, and indeed has relied upon, the random nature

of this survey.

46 BPA has reported the number surveyed to be as high as 100.

NACA suggests the number of relevant responses may be as low

as 40. No matter how NACA shuffles the data, however, the basic

conclusion on which we rely comes forward. The great majority

of formulating companies do not discharge any process waste

water pollutants into navigable waters.

47 If, as NACA asserts, future regulations outlaw these indirect

discharges, NACA may challenge those regulations. We cannot

overturn regulations because companies able to comply with them

might be unable to comply with supposed future rules.

46a

—“The best practicable control technology currently

available for most plants in the industry appears

to be an evaporative system having no effluent. For

those plants that cannot effect complete evaporation

of their process waste water, partial evaporation in

conjunction with disposal in an approved landfill ap-

pears to be the best alternative.” **

This study contacted 105 companies, getting 91 usable

responses. Of these 91, 66 discharged no waste water.

- Only 5 discharged directly to navigable waters, and an-

other 20 discharged to private treatment facilities or

practiced deep well injection or ocean dumping. Thus 73

per cent of the companies have no discharge at all, and

95 per cent comply with these regulations. The results

are virtually identical to ESE’s results. Whatever the

failings of these studies, the numbers clearly show that

the great majority of formulators already meet the limi-

tations, and it follows that meeting the regulations is

practicable for the industry looked at as a whole.

NACA does not seriously dispute that conclusion. Rather

NACA suggests that we should not rely on the numbers

at all and that the category should not be looked at as a

whole. NACA attacks the methodology of the ESE sur-

vey because two different survey forms were used, those

were not completely filled out, the results have been in-

consistently reported, and the survey failed to generate

any information on the effectiveness of any pre-discharge

waste water treatment systems. Neither we nor EPA rely

on this survey for anything beyond the information that

was collected—the company’s formulating process and

whether or not it generated or discharged process waste

water. That other questions were not asked or answered

is for this purpose irrelevant. Similarly, that the survey

48 NACA notes that this conclusion is tempered by the word

“appears” and by the qualification that air pollution problems that

may be connected with evaporation should be studied.

47a

results have been inconsistently reported is of no matter

so long as the final tabulation is accurate. NACA chal-

lenges the survey it submitted because that survey was not

designed to serve the purpose for which EPA used it,

was hastily done, and left many questions unanswered.

Again, our use of it, like EPA’s is only for the results

it did collect, not for whatever it may have failed to de-

termine.

NACA next suggests that the formulating category

should have been broken into two subcategories because

EPA’s first contractor, Weston, so recommended and be-

cause it is “obvious . . . that formulators whose very op-

erations involve the use of water and other liquids will

generate wastewater and cannot achieve zere discharge.”

EPA was in no way bound to accept its contractor’s sug-

gestion. Our inquiry is only whether the solution EPA

did adopt is rational and supported by the record.

The ESE survey collected information on the type of

process used as well as waste generation and discharge.“

The survey does not support NACA’s assertion that plants

using water-based processes inevitably must discharge

process waste water. Of the 47 responding facilities, 20

produce liquid-based pesticides. Of these 20, only 2 run

afoul of these regulations by discharging process waste

water directly to navigable waters. An additional 8 facili-

ties discharge waste water to private treatment facilities.

Half the liquid-based formulators have no discharge at

all. These numbers clearly show that even formulators us-

ing liquid-based processes can and do achieve zero dis-

charge.

49 For four of the companies no process is indicated. We shall

assume that the one of these which did discharge waste water

used a water-based process and that the other three used dry-based

processes. This puts the uncertain data in the light most favorable

to NACA.

48a

Given EPA’s supported finding on the basis of the sur-

vey that the industry in large part achieved zero dis-

charge, EPA did not need to go through the further steps

of designating some number of these plants “exemplary”

and averaging the zero discharge reports of the ex-

emplary plants to set a zero discharge limit for the sub-

category. To be sure, it might have been well for EPA

to visit some of the facilities reporting zero discharge in

order to verify the reports, but at some point EPA must

be able to rely on information provided by industry, and

here the companies had no incentive to report discharges

below actual levels, thereby inviting regulations they could

not meet.

We turn now to the factors the statute mandates that

EPA consider. In particular, NACA argues that EPA

has failed adequately to consider “non-water quality

environmental impact” and “the total cost of application

of technology in relation to the effluent reduction benefits

to be achieved.” 33 U.S.C. § 1814(b) (1) (B).

As we have said, the cost/benefit comparison man-

dated by Congress is “intended to limit the application

of technology only where the additional degree of effluent

reduction is wholly out of proportion to the costs of

achieving such marginal level of reduction for any class

or category of sources.” Legislative History, supra, at

170; Weyerhaeuser, at 1045 & n. 52. Congress did not

intend cost to be an unwieldy barrier to attainment of

pollution control goals. We have already explained the na-

ture of our review.

EPA devoted significant effort to discovering the econ-

omic impact of these regulations on the formulating and

packaging segment of the industry. Not only did EPA

attempt to find out the number of companies that would

have to incur new costs to comply with the regulations,

but it also prepared estimates of the cost of compliance on

the assumption that small, medium, and large plants

would have ‘9 build evaporation treatment systems from

scratch. NACA attacks these cost estimates on two fronts.

The first is that EPA failed to consider adequately or ac-

curately the cost of hauling waste water or sludge re-

maining after evaporation to a landfill. EPA’s estimates

are only for evaporation systems, not the alternative ac-

ceptable technology of hauling all waste water to a land-

fill. But evaporation is the more expensive of the two

alternatives.°° Therefore, there was no reason to consider

hauling separately. EPA further asserts that the cost of

hauling the sludge left after evaporation is included in

its assessment of annual “operating/maintenance” costs

for the evaporation system."' Though it might have been

well for EPA to provide a more detailed itemization of its

cost estimates, given the limited scope of our review, we

will not impose any such mandatory duty. We have no

basis on which to doubt the EPA’s assertion in this

regard.

NACA’s second attack is that EPA used unrealistic

estimates of evaporation rates. EPA used the median

evaporation rate for the country in developing its esti-

mates. NACA recognizes this by saying that the figure

50 This is true even if NACA’s figure for the cost of contract

hauling is substituted for EPA’s. EPA assumed hauling would cost

$5 per gallon and that hauling all waste water would, therefore,

cost about $4600 per year for a medium size plant, about half the

$9100 annual operating cost of an evaporation system. Using the

$8.50 per gallon cost suggested by NACA, the annual cost for the

same plant would go up to about $7800, still significantly less than

the cost of the evaporation system.

51 Again, even if EPA used the wrong price for contract hauling,

see note 50, supra, its analysis would not be significantly in error.

Operating maintenance costs comprise a very small percentage of

the total annual operating costs, and, we assume, hauling costs are

less than all the operating costs. Even if all the operating costs

were for hauling, the $8.50 price would increase total operating

cost by only $700 for the medium plant, raising the total annual

cost to about $9800, an increase of only adout 8% which would in

turn increase the estimated cost per gallon at the medium plant

from $0.073 per gallon to $0.079 per gallon.

used “overestimates the annual evaporation rate for

approximately half the nation” and “over half the pesti-

cide formulation plants”. EPA is entitled to look at costs

on an industry-wide basis as opposed to plant-by-plant.

To do so EPA must be able to make some assumption

about the conditions facing the industry. Certainly, using

an appropriately chosen average figure is a legitimate

statistical technique, especially given that EPA is doing

no more than developing rough estimates to help it de

termine whether the cost “is wholly out of proportion”

to the benefit. Moreover, EPA notes that the evaporation

tank volumes allotted are more than ample to accom-

modate the very slow build up of waste water that might

accumulate where evaporation is significantly less than

the national average. This build up can be hauled per-

iodically to landfills.

Given EPA’s determination that the cost of installing

and operating an evaporation system would be acceptable

even for a plant that starts with no system at all and

that most formulators already comply with the regula-

tions, EPA gave ample consideration to the comparison

of cost with benefit. To be sure, the record contained

only scanty data on the quantity of pollutants in formu-

lators’ waste water.”? On the other hand, EPA has dis-

covered that the cost of compliance for the industry is

small. Any discharges that trigger a requirement for a

company to incur new costs must bear some pollutants,

or they would not be illegal. Therefore, eliminating those

discharges will produce benefits. This seems to be the

implicit logic of the Agency, and we find it persuasive.

It is rational to conclude that the small costs to the

industry are not wholly out of proportion to the benefits.

We must remember that the goal of the Act is to elimi-

nate discharges of pollutants into navigable waters, and

this effluent limitation accomplishes that goal.

company data, and plant visits. App. 1711.

The Agency must also “take into account ... non-

water quality environmental impact”. The District of

Columbia Circuit has held that this means the Agency

must inform itself of the magnitude of potential prob-

lems and reach an “express and considered conclusion

about their bearing’. Weyerhaeuser, at 1045. The

Agency has done so, though in a most cursory way. 43

Fed. Reg. 17776, 17780 (1978). The Agency noted that

the major problem would be sludge and concentrated

waste disposal. Though there is no specific finding of the

magnitude of the problem and no express statement of

conclusions, it is clear that EPA considered the problems

and decided they were not of sufficient magnitude to

prevent promulgation of these regulations. The Agency

noted that it has published guidelines on solid waste

disposal, 40 C.F.R. Part 241, and that it is in the process

of developing regulations under the Resource Conserva-

tion and Recovery Act of 1976, 42 U.S.C. §§ 6901, et

seq., to regulate hazardous wastes. We infer that EPA

concluded that waste disposal can be accomplished at

an acceptable cost to the environment. As to air pollu-

tion EPA asserts in its brief that the Resource Con-

servation and Recovery Act regulations will deal with

air pollution associated with disposal of hazardous waste.

Though no detailed study appears in the record, the

record reveals that EPA was aware of the problem, did

not consider it significant, and felt that, where necessary,

treatment could prevent air pollution. App. 1233.

“TS]ince Congress intended EPA’s internal structure to

53 We need not concern ourselves at this time with the additional

economic cost, if any, to the pesticide industry of future compliance

with these regulations. EPA can more properly consider such

costs in proceedings concerning those regulations. Any attempt to

assess the costs of compliance with unpromulgated regulations

would be premature and highly speculative. We know of no law

that prohibits an agency from attacking the evils within its juris-

diction in a piece-meal fashion. A contrary rule would make the

regulatory process unworkable.

expressly considered the probable environmental impacts

of its regulations.” Weyerhaeuser, at 1053.

Finally, NACA challenges EPA’s decision that plants

which both manufacture and formulate pesticides must

meet the limits for manufacturing plants with no credit
