National Emission Standards for Hazardous Air Pollutants:

Revision of Source Category List and Schedule for Standards Under

Section 112 of the Clean Air Act

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of revisions to the list of categories of major and area

sources and revisions to the promulgation schedule for standards.

-----------------------------------------------------------------------

SUMMARY: This notice publishes revisions to the list of categories of

major and area sources and revisions to the schedule for the

promulgation of standards for sources of hazardous air pollutants

(HAPs). Required under section 112(c) and (e) of the Clean Air Act

(CAA), the source category list and schedule for standards constitute a

significant part of EPA's agenda for

[[Page 63026]]

regulating stationary sources of air toxics emissions. The list and

schedule were most recently published in the Federal Register on

February 12, 1998 (63 FR 7155).

Today's notice meets the requirement in section 112(c)(1) to

publish periodically, but at least once every 8 years, a list of all

categories of sources reflecting revisions since the initial list was

published. Several of the revisions identified in today's notice have

previously been published in actions associated with proposing and

promulgating emission standards for individual source categories, and

public comment has been taken in the context of those actions. Some of

the revisions in today's notice have not been reflected in any previous

notices and are being made without public comment on the

Administrator's own motion. Such revisions are deemed by EPA to be

without need for public comment based on the nature of the actions.

Today's notice also announces some anticipated actions.

EFFECTIVE DATE: November 18, 1999.

ADDRESSES: Docket No. A-90-49, containing supporting information used

in development of this notice, is available for public inspection and

copying between 8 a.m. and 5:30 p.m., Monday through Friday, excluding

legal holidays. The docket is located in EPA's Air and Radiation Docket

and Information Center, Waterside Mall, Room M-1500, 401 M Street, SW.,

Washington, DC 20460, or by calling (202) 260-7548. A reasonable fee

may be charged for copying docket materials.

today's notice is also available through the Technology Transfer

Network (TTN). Following signature, a copy of the notice will be posted

on the TTN's policy and guidance page for newly proposed or promulgated

rules http://www.epa.gov/ttn/oarpg. The TTN provides information and

technology exchange in various areas of air pollution control. If more

information regarding the TTN is needed, call the TTN HELP line at

(919) 541-5384.

I. What is the History of the Source Category List and Schedule?

The CAA amendments of 1990 (Pub. L. 101-549) require, under section

112, that EPA list all categories of major sources emitting HAPs and

such categories of area sources warranting regulation, and promulgate

national emission standards for HAPs (NESHAP) to control, reduce, or

otherwise limit the emissions of HAPs from such categories of major and

area sources. Pursuant to the various specific listing requirements in

section 112(c), we published on July 16, 1992 (57 FR 31576), a list of

174 categories of major and area sources--referred to as the ``initial

list''--for which we would develop emission standards. Following this

listing, pursuant to requirements in section 112(e), on December 3,

1993 (58 FR 63941), we published a schedule for the promulgation of

emission standards for each of the 174 listed source categories.

When we publish notices that affect actions relating to individual

source categories, it is important to reflect the resultant changes on

the list and schedule. On June 4, 1996 (61 FR 28197), we published a

notice that referenced all previous listing and schedule changes and

consolidated those actions, along with several new actions, into a

revised source category list and schedule. We published a subsequent

notice on February 12, 1998 (63 FR 7155), which again updated the list

and schedule; and on May 17, 1999 (64 FR 26743), we published a notice

which announced scheduling changes for promulgating standards. You

should read these previous notices for information relating to

development of the initial list and schedule and subsequent changes.

II. Why is EPA Issuing This Notice?

This notice announces all list and schedule changes, as well as

proposed changes, that have occurred since we last updated the list on

February 12, 1998 (63 FR 7155) and the schedule on May 17, 1999 (64 FR

26743). There are also a few anticipated future actions which are being

announced in this notice; however, the proposed and anticipated actions

are not reflected in Table 1 at the end of today's notice since these

changes are tentative and are not being effected by this notice. We are

announcing these possible future actions to give the reader the maximum

notice of likely future actions. The list of changes, along with the

affected source categories, are listed below:

A. Changes to Source Category Names

The source category list and promulgation schedule, updated to

include today's actions, as well as actions from previous notices, are

presented in Table 1. Table 1 also includes Federal Register citations

for notices related to the source categories (Table 1 omits proposal

notices once a rule or rule amendment has been promulgated). Source

categories for which revisions have been made in today's notice are

marked in Table 1 for ease in discerning where revisions have been

made.

For general descriptions of source categories listed in Table 1,

the reader is referred to Docket No. A-90-49 (EPA-450/3-91-030,

entitled ``Documentation for Developing the Initial Source Category

List''), and the Federal Register notice for the first revision of the

source category list and schedule (61 FR 28197; June 4, 1996). For

subsequent changes to descriptions of source categories for which a

rule has been promulgated, the reader is advised to consult Table 1 for

the citation of the Federal Register notice which will include the

amended definition and corresponding rule applicability.

III. What Are the Revisions EPA is Making to the Source Category

List and Schedule?

The following sections describe revisions to the source category

list since the February 12, 1998 notice and the schedule since the May

17, 1999 notice, as well as proposed and anticipated future actions.

A. Changes to Source Category Names

We are renaming the following source categories so that the names

better describe the source category:

1. ``Tire Production'' is renamed ``Rubber Tire Manufacturing.''

2. ``Plywood/Particle Board Manufacturing'' is renamed ``Plywood

and Composite Wood Products.''

3. ``Baker's Yeast Manufacturing'' is renamed ``Manufacturing of

Nutritional Yeast'' to clarify the scope as well as distinguish it from

the regulation of bakeries (63 FR 55812).

4. ``Paint Stripper Users'' is renamed ``Paint Stripping

Operations.''

5. ``Chromium Refractories Production'' is renamed ``Refractories

Manufacturing.'' Due to source testing that confirmed major sources of

HAP emissions (i.e., greater than or equal to 10 tons per year (tpy) of

a single HAP or 25 tpy aggregate HAPs) from several types of refractory

manufacturing, we have determined that this source category should be

expanded to include several types of refractory manufacturing.

6. ``Flat Wood Paneling (Surface Coating)'' is renamed ``Wood

Building Products (Surface Coating).''

7. ``Ferroalloys Production'' is renamed ``Ferroalloys Production:

Silicomanganese and Ferromanganese.'' We have determined that these are

the only alloy types covered by the rule.

8. ``Steel Pickling--HCl Process'' is renamed ``Steel Pickling--HCl

Process Facilities and Hydrochloric Acid Regeneration Plants.'' We have

decided, for informational purposes, that ``Hydrochloric Acid

Regeneration Plants'' should be added to the title since the rule

affects spent acid regeneration in addition to steel pickling

processes.

9. ``Stationary Internal Combustion Engines'' is renamed

``Reciprocating Internal Combustion Engines.''

10. ``Stationary Turbines'' is renamed ``Combustion Turbines.''

11. ``Rocket Engine Test Firing'' is renamed ``Rocket Testing

Facilities.''

B. Correction to a Previous Notice

This Federal Register notice announces one change to correct the

name of the Fume Silica Production source category. This source

category is one of the 174 source categories initially listed on July

16, 1992 (57 FR 31576). The name is being changed to correct a

typographical error. The correct name of this source category is

``Fumed Silica Production.''

C. Changes to the Promulgation Schedule

In the December 3, 1993 notice (58 FR 63941), we scheduled the

initially listed source categories for regulation such that 50 percent

(87 of 174) would be promulgated by November 15, 1997. Consequently, to

continue to satisfy the numerical and temporal requirements of CAA

section 112(e)(1), any change that would delay the deadline for a

source category scheduled for regulation by November 15, 1997, must be

offset by a corresponding shifting of a source category from the

November 15, 2000 regulatory timeframe to the November 15, 1997

timeframe.

1. Pulp and Paper Production

We are changing the schedule for Pulp and Paper Production, which

we included in the initial source category schedule in December 1993,

from November 15, 1997 to November 15, 2000. The Pulp and Paper

Production maximum achievable control technology (MACT) standard (40

CFR part 63, subpart S), applicable to pulping, bleaching, and paper

making operations, was promulgated on April 15, 1998. The MACT standard

for chemical recovery combustion sources at kraft, soda, sulfite and

stand-alone semichemical pulp mills (40 CFR part 63, subpart MM) was

also proposed on April 15, 1998. To address comments received on the

April 15, 1998 proposal, we anticipate the need to issue a supplemental

notice to the proposal before we can promulgate the standard.

Consequently, we are rescheduling the Pulp and Paper Production source

category for the November 15, 2000 regulatory timeframe, which will

allow us time to address issues raised by comments received on the

April 15, 1998 proposal.

2. Aerosol Can-Filling Facilities and Antimony Oxides Manufacturing

To ensure that we meet the CAA section 112(e)(1) scheduling

requirements, we are countering the Pulp and Paper Production source

category scheduling change by moving two source categories, Aerosol

Can-Filling Facilities and Antimony Oxides Manufacturing, forward to

the November 15, 1997 regulatory timeframe. This move more than meets

the statutory requirement of promulgation of 50 percent of the

initially listed source categories by November 15, 1997. We are also

delisting these two source categories in actions under subsection E of

this section, ``Deletion of Source Categories.''

D. Addition of Source Categories

Pursuant to section 112(c)(5), the Administrator may at any time

add categories to the initial source category list based on the same

criteria used to develop the initial list. Section 112(c)(5) also

states that the Administrator shall promulgate standards to regulate

HAP emissions from these added categories and subcategories within 10

years after enactment of the CAA amendments of 1990 (i.e., by November

15, 2000) or within 2 years after the date on which the category or

subcategory was listed, whichever is later.

In response to new information, today's notice reflects the listing

of Cellulosic Sponge Manufacturing as a source category because it

contains facilities meeting the CAA section 112(a)(1) major source

criteria. This source category includes facilities that manufacture

cellulosic sponges using the viscose process. The HAPs are emitted from

the xanthation,

[[Page 63028]]

regeneration/washing, and salt recovery processes. The HAPs that are

emitted from these processes include carbon disulfide and carbonyl

sulfide. Pursuant to section 112(c)(5), this category is scheduled for

standards promulgation by November 16, 2001. You should refer to

subsection H of this notice for a discussion of the anticipated

subsumption of this source category into a broader cellulose source

category.

With respect to the Clay Products source category, EPA anticipates

replacing the existing source category with four new source categories.

The Clay Products source category comprises four distinctly different

types of processes and products which will form the bases of the new

source categories. Those four anticipated source categories are: Brick

and Structural Clay Products Manufacturing, Ceramics Manufacturing,

Clay Minerals Processing, and Lightweight Aggregate Manufacturing. Each

of these source categories has unique emissions characteristics,

emissions controls, and economic considerations. We expect to propose

and promulgate separate MACT standards for each of the anticipated four

source categories. When each of the standards is proposed, that

proposal will add the new source category to the source category list.

The public will then have an opportunity to comment on adding these

source categories in conjunction with the MACT proposal. Pursuant to

section 112(c)(5), these source categories will be scheduled for

promulgation by November 15, 2000, the same date that the original Clay

Products source category was scheduled for promulgation.

Today's notice also involves one other anticipated action to add a

source category named ``Wet-Formed Fiberglass Mat Production.'' During

the development of the Asphalt Roofing Manufacturing and Asphalt

Processing MACT standards, industry representatives alerted EPA about

the wet-formed fiberglass mat manufacturing industry, and its

relationship to the asphalt roofing production industry and companies.

We determined that wet-formed fiberglass mat manufacturing facilities

have the potential to be major sources. We have decided to develop a

separate MACT standard for the wet-formed fiberglass mat industry

because the production processes and pollutant emissions are different

from the asphalt roofing manufacturing and the asphalt processing

industries. We anticipate proposing a MACT standard for Wet-Formed

Fiberglass Mat Production in late 1999. That MACT proposal will add the

source category to the source category list, at which time the public

will have an opportunity to comment on adding this source category. We

will be scheduling this source category for MACT promulgation by 2

years after the date of listing of the source category, as specified in

section 112(c)(5) of the CAA.

E. Deletion of Source Categories

The Administrator may, where appropriate, delete categories of

sources on the Administrator's own motion or on petition. In today's

notice, we are deleting two source categories, Aerosol Can-Filling

Facilities and Antimony Oxide Manufacturing, on the Administrator's own

motion. As discussed in the initial list notice (57 FR 31576), we

included these categories on the list because at the time, we believed

there were either major sources in each category, or sources collocated

on the premises of major sources. As such, CAA section 112(c)(1)

requires that we list these source categories. In today's notice, we

are deleting these source categories because available data indicate

that there are no major sources in either source category.

This section does not include categories of sources which are being

removed from the list by way of subsumption into other listed

categories. Subsumption is not a deletion, but rather an action to

combine source categories on the list. See subsection H of this section

for information on source categories being subsumed into other listed

source categories.

1. Aerosol Can-Filling Facilities

The Aerosol Can-Filling Facilities source category was initially

listed in July 1992 and was based on an industry survey performed by

EPA in 1987 which indicated that several fillers emitted HAPs in excess

of major source levels. The HAPs included methyl chloroform (also known

as 1,1,1-trichloroethane), methylene chloride (also known as

dichloromethane), tetrachloroethylene (also known as

perchloroethylene), and trichloroethylene. Work on the rule development

for aerosol can-filling began in 1997. Because the information that

supported the initial listing was limited and more than 10 years old,

new data was obtained.

A comprehensive list of both custom and captive fillers, which

totaled 149 fillers, was obtained from industry trade associations. The

EPA's Toxic Release Inventory (TRI) for 1997 was then accessed. Reports

were obtained for 35 of the 149 fillers. We do not believe that the

non-reporting fillers emit HAPs in appreciable quantities. A facility

is not required to complete EPA Form R (Toxic Chemical Release

Inventory Reporting Form) if it manufactures or produces less than 12.5

tpy or uses less than 5 tpy of any chemical or chemical category on the

Superfund Amendments and Reauthorization Act (SARA) section 313 toxic

chemicals list.

The HAPs reported included methyl chloroform, methylene chloride,

methanol, methyl ethyl ketone, tetrachloroethylene, toluene,

trichloroethylene, and xylene. Of the 35 reporting fillers, only one

reported emitting HAPs at more than major source levels (10.3 tons of

dichloromethane) in 1997. That filler was subsequently contacted to

obtain a copy of its 1998 Form R. That report indicates that 7 tons of

dichloromethane (the highest HAP emitted) and 14 tons of combined HAPs

were emitted in 1998. The filler has since committed, through its Title

V permit, to a federally enforceable requirement that caps HAP

emissions to less than 10 tpy for any single HAP and 25 tpy for any

combination of HAPs.

In summary, there are no major sources in this source category.

Consequently, we are removing this category from the list of major

source categories selected for regulation.

2. Antimony Oxides Manufacturing

The source category consists of four sources engaged in the

production of antimony oxide, a white, crystaline powder used mainly as

a flame retardant in plastics and textiles. Manufacturing processes

include oxidation of antimony ingots or crude antimony oxide in kiln-

type furnaces followed by radiative cooling and collection of refined

product oxide in baghouses. The initial listing of Antimony Oxides

Manufacturing as a major source category was based on the calculation

which assumed that 1 percent of the annual production of antimony oxide

in 1987 (20,700 metric tons) was released to the atmosphere.

Since the initial listing, we have visited all four sources and

reviewed permit conditions to estimate emissions. In addition, two of

the sources performed stack tests to quantify their actual emissions of

antimony. Based on the above information, it is our conclusion that no

antimony oxides manufacturing facility emits antimony compounds

approaching major source levels. Our best estimate for the highest

emitting source is less than 6 tpy. Estimates for the other three

sources range from about 20 pounds per year to 3 tpy. Therefore, since

there are no major sources in this category, we are removing it from

the list.

[[Page 63029]]

F. Reassignment of a Source Category to a Different Industry Group

On the initial source category list, the Rocket Testing Facilities

source category was categorized under the Miscellaneous Processes

industry group. The Rocket Testing Facilities source category includes

facilities that fire rocket engines to determine performance

specifications or compliance with other functional standards. The

category includes, but is not limited to, test firing of solid and

liquid fuel rocket engines. Therefore, this source category more

appropriately belongs under the Fuel Combustion industry group. The

movement of this source category will have no effect on the

promulgation date of the MACT standard.

Today's notice also updates the source category list to reflect the

movement of the Tetrahydrobenzaldehyde Production source category from

the Miscellaneous Processes industry group to the Production of Organic

Chemicals industry group. You should refer to subsection H of this

notice to learn more about the subsumption of this source category.

G. Changes to the Scope of a Source Category

Today's action serves to broaden the Boat Manufacturing source

category to include boats that are constructed of aluminum. In the data

gathering process for the Boat Manufacturing source category, we found

that there was a similarity in some types of emission points between

boats made of synthetic material and boats made of aluminum. In

addition, data gathered for aluminum boat painting operations indicate

that these operations would be addressed more appropriately in the Boat

Manufacturing source category, rather than in the Miscellaneous Metal

Parts Coating source category. Broadening the scope of the Boat

Manufacturing source category to include the manufacturing of aluminum

boats will not result in any change of schedule for this source

category.

H. Subsumptions of Source Categories

Today's notice updates the source category list to reflect the

subsumption of eleven previously listed source categories under the

Agricultural Chemicals Production industry group into a single source

category, and also broadens the scope of that category to include a

number of other pesticide active ingredient (PAI) production operations

that were not included on the initial source category list. For further

information, you should refer to a June 23, 1999, notice (64 FR 33549),

which promulgated the MACT standard for PAI production. The eleven

source categories subsumed were: 4-Chloro-2-Methylphenoxyacetic Acid

Production, 2,4-D Salts and Esters Production, 4,6-Dinitro-o-Cresol

Production, Butadiene-Furfural Cotrimer (R-11) Production, Captafol

Production, Captan Production, Chloroneb Production, Chlorothalonil

Production, Dacthal Production, Sodium Pentachlorophenate Production,

and Tordon (tm) Acid Production. In developing the proposed PAI MACT

standard (61 FR 57602, November 10, 1997), we decided not to set MACT

for each individual source category, but to aggregate them under the

same source category. Data gathered from the PAI production industry

indicated that the process equipment, emission characteristics, and

applicable control technologies were sufficiently similar for the broad

group of sources such that it was appropriate for EPA to regulate them

under a single MACT standard.

Today's notice updates the source category list to reflect the

subsumption of the Tetrahydrobenzaldehyde Production source category

into the Synthetic Organic Chemical Manufacturing source category. For

more information, you should refer to a May 12, 1998 notice (63 FR

26078), which promulgated amendments to the Synthetic Organic Chemical

Manufacturing Industry NESHAP (commonly known as the Hazardous Organic

NESHAP (HON)).

You should refer to a November 7, 1996 notice (61 FR 57602) and the

February 12, 1998 source category notice (63 FR 7155), to learn about

an anticipated listing action involving the subsumption of a number of

source categories into one source category called the ``Miscellaneous

Organic Chemical Processes'' source category. We are now considering

combining the source categories into two new source categories instead

of one. The two new source categories would be called the

``Miscellaneous Organic Chemical Processes'' source category and the

``Miscellaneous Coating Processes'' source category. The scope of the

Miscellaneous Organic Chemical Processes source category would also be

broadened to cover more organic chemical processes, in addition to the

process already listed. Each of these source categories is scheduled

for promulgation no later than November 15, 2000; thus, the two new

source categories would also be scheduled for that regulatory

timeframe. The proposal notices for those MACT standards will serve as

the official action to combine and rename the new source categories.

The public will have an opportunity to comment on actions as part of

those MACT proposals.

We also refer the reader to a December 14, 1998 notice (63 FR

68832), which announced combining two source categories, Amino Resins

Production source category and Phenolic Resins Production source

category, into a single new source category called ``Amino/Phenolic

Resins Production'' for purposes of efficiency in rulemaking.

Today's notice involves another anticipated action regarding the

combining of the seven categories related to cellulose production into

two source categories called, ``Cellulose Ethers Production'' and

``Miscellaneous Viscose Processes.'' We are considering the combining

of Carboxymethylcellulose Production and Cellulose Ethers Production

into the Cellulose Ethers Production. We are also considering the

combining of four existing source categories into a new source category

called, ``Miscellaneous Viscose Processes.'' This newly defined source

category would subsume the Rayon Production source category, Cellulose

Food Casing Manufacturing source category, Cellophane Production source

category, and Cellulosic Sponge Manufacturing source category. Each of

these source categories is scheduled for promulgation no later than

November 15, 2000; thus these two newly defined source categories would

also be scheduled for that regulatory timeframe. The proposal notices

for those MACT standards will serve as the official actions to combine

the source categories and to name the newly defined source categories.

The public will have the opportunity to comment on those actions as

part of the Miscellaneous Cellulose Production MACT proposal.

IV. Is This Action Subject to Judicial Review?

The CAA section 112(e)(3) states that the determination of

priorities for promulgation of standards for the listed source

categories is not a rulemaking and is not subject to judicial review,

except that, failure to promulgate any standard pursuant to the

schedule established under section 112(e) shall be subject to review

under section 304 of the CAA. Section 112(e)(4) states that,

notwithstanding section 307 of the Act, no action of the Administrator

listing a source category or subcategory under section 112(c) shall be

a final Agency action subject to judicial review, except that any such

action may be reviewed under section 307 when the Administrator issues

emission standards

[[Page 63030]]

for such pollutant or category. Therefore, today's notice is not

subject to judicial review.

V. Is EPA Asking for Public Comment?

Prior to issuance of the initial source category list, we published

a draft initial list for public comment (56 FR 28548, June 21, 1991).

Although we were not required to take public comment on the initial

source category list, we believed it was useful to solicit input on a

number of issues related to the list. Indeed, in most instances, even

where there is no statutory requirement to take comment, we solicit

public comments on actions we are contemplating. Section 112(e)(3)

required that we offer opportunity for public comments on the initial

source category schedule, which we published as a draft in a September

24, 1992 notice and subsequently published in final form on December 3,

1993. We have decided, however, that it is unnecessary to solicit

additional public comment on the revisions reflected in today's notice.

Where we believe it is useful to solicit input on certain actions, we

will offer interested parties an opportunity to provide comments on

proposed individual MACT standards.

VI. Administrative Requirements

Today's notice is not a rule; it is essentially an information

sharing activity which does not impose regulatory requirements or

costs. Therefore, the requirements of Executive Order 13045 (Protection

of Children from Environmental Health Risks and Safety Risks),

Executive Order 13084 (Consultation and Coordination with Indian Tribal

Governments), Executive Order 13132 (Federalism), the Regulatory

Flexibility Act, the National Technology Transfer and Advancement Act,

and the Unfunded Mandates Reform Act do not apply to today's notice.

Also, this notice does not contain any information collection

requirements and, therefore, is not subject to the Paperwork Reduction

Act, 44 U.S.C. 3501 et seq.

Under Executive Order 12866 (58 FR 51735, October 4, 1993), a

regulatory action determined to be ``significant'' is subject to OMB

review and the requirements of the Executive Order. The Order defines

``significant'' regulatory action as one that is likely to lead to a

rule that may either (1) Have an annual effect on the economy of $100

million or more, or adversely affect a sector of the economy,

productivity, competition, jobs, the environment, public health or

safety, or State, local or tribal governments or communities; (2)

Create a serious inconsistency or otherwise interfere with an action

taken or planned by another agency; (3) Materially alter the budgetary

impact of entitlements, grants, user fees, or loan programs or the

rights and obligations of recipients thereof; or (4) raise novel legal

or policy issues arising out of legal mandates, the President's

priorities, or the principles set forth in the Executive Order.

Pursuant to the terms of Executive Order 12866, OMB considers

today's notice a ``significant regulatory action'' within the meaning

of the Executive Order. For this reason, this action underwent review

by the OMB.

------------------------------------------------------------------------

a Only sources within any category located at a major source shall be

subject to emission standards under CAA section 112 unless a finding

is made of a threat of adverse effects to human health or the

environment for the area sources in a category. All listed categories

are exclusive of any specific operations or processes included under

other categories that are listed separately.

b This schedule does not establish the order in which the rules for

particular source categories will be proposed or promulgated. Rather,

it requires that emissions standards pursuant to CAA section 112(d)

for a given source category be promulgated by the specified date.

The markings in the ``Statutory Promulgation Date/Federal Register

Citation'' column of Table 1 denote the following:

(A): final amendment to a final rulemaking action

(a): proposed amendment to a final rulemaking action

(C): correction (or clarification) published subsequent to a proposed

or final rulemaking action

(F): final rulemaking action

(N): notice to announce general information, such as an Agency

decision, availability of new data, administrative updates, etc.

(P): proposed rulemaking action

(R): reopening of a proposed action for public comment

(S): announcement of a stay, or partial stay, of the rule requirements

Moved: the source category is relocated to a more appropriate industry

group

Subsumed: the source category is included within the definition of

another listed category and therefore is no longer listed as a

separate source category

Renamed: the title of this source category is changed to a more

appropriate title

Deleted: the source category is removed from the source category list

c The Publicly Owned Treatment Works (POTW) Emissions source category

had a statutory deadline for regulatory promulgation of November 15,

1995, as established by CAA section 112(e)(5). However, for purposes

of determining the 18-month period applicable to the POTW source

category under section 112(j)(2), the promulgation deadline was

November 15, 1997. This latter date is consistent with the section

112(e) schedule for the promulgation of emissions standards, as

published in the Federal Register on December 3, 1993 (58 FR 63941).

d Equipment handling specific chemicals for these categories or subsets

of these categories is subject to a negotiated standard for equipment

leaks contained in the Hazardous Organic NESHAP (HON), which was

promulgated on April 22, 1994. The HON includes a negotiated standard

for equipment leaks from the SOCMI category and 20 non-SOCMI

categories (or subsets of these categories). The specific processes

affected within the categories are listed in Section XX.X0(c) of the

March 6, 1991 Federal Register notice (56 FR 9315).

e A finding of threat of adverse effects to human health or the

environment was made for each category of area sources listed.
