Standards of Performance for New Stationary Sources National

Emission Standards for Hazardous Air Pollutants, Addition of Method 29

to Appendix A of Part 60 and Amendments to Method 101A of Appendix B of

Part 61

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule and notice of public hearing.

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

SUMMARY: The EPA is proposing to add Method 29, ``Determination of

Metals Emissions from Stationary Sources,'' to appendix A of part 60,

and to propose amendments to Method 101A of appendix B of part 61.

Method 29 is being proposed so that it can be used to determine

cadmium, lead, and mercury emissions from municipal waste combustors

(MWC) under subpart Ea of part 60. The amendments to Method 101A of

appendix B of part 61 are intended to expand that method's

applicability, and to add procedures for handling and analyzing samples

collected by the sampling train.

A public hearing will be held, if requested, to provide interested

persons an opportunity for oral presentation of data, views, or

arguments concerning the proposed rule.

DATES: Comments. Comments must be received on or before November 21,

1994.

Public Hearing. If anyone contacts the EPA requesting to speak at a

public hearing by October 11, 1994, a public hearing will be held on

October 20, 1994, beginning at 10 a.m. Persons interested in attending

the hearing should call the contact mentioned under ADDRESSES to verify

that a hearing will be held.

Request to Speak at Hearing. Persons wishing to present oral

testimony must contact the EPA by October 11, 1994.

ADDRESSES: Comments. Comments on the proposal should be submitted (in

duplicate if possible) to: Air and Radiation Docket and Information

Center (Mail Code 6102), ATTN: Docket No. A-94-28, room 1500, U.S.

Methods 29 and 101A Item in EMTIC Electronic Bulletin Board

1. ``Emissions Test Method 29: Determination of Metals Emissions

From Stationary Sources (1994 Proposal),'' EPA-454/R-94-016, April

1994.

I. Summary of Proposed Method 29 and Method 101A Revisions

Under Subparts Ca and Ea, the EPA is proposing guidelines and

standards to regulate mercury, cadmium, and lead emissions from MWC's.

Method 29 is being proposed for addition to Appendix A of 40 CFR Part

60 and will serve as the compliance test method for MWC's for mercury,

cadmium, and lead. Method 29 is applicable to the determination of

antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), cadmium (Cd),

chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), manganese (Mn),

mercury (Hg), nickel (Ni), phosphorus (P), selenium (Se), silver (Ag),

thallium (Tl), and zinc (Zn) emissions from stationary sources. Method

29 may be used to determine particulate emissions in addition to the

metals emissions if the prescribed procedures and precautions are

followed. For both methods, a stack sample is withdrawn isokinetically

from the source, particulate emissions are collected in the probe and

on a heated filter, and gaseous emissions are then collected in an

aqueous acidic solution of hydrogen peroxide (analyzed for all metals

including Hg) and an aqueous acidic solution of potassium permanganate

(analyzed only for Hg). The recovered samples are digested, and

appropriate fractions are analyzed for Hg by cold vapor atomic

absorption spectroscopy (CVAAS) and for Sb, As, Ba, Be, Cd, Cr, Co, Cu,

Pb, Mn, Ni, P, Se, Ag, Tl, and Zn by inductively coupled argon plasma

emission spectroscopy (ICAP) or atomic absorption spectroscopy (AAS).

Graphite furnace atomic absorption spectroscopy (GFAAS) is used for

analysis of Sb, As, Cd, Co, Pb, Se, and Tl if these elements require

greater analytical sensitivity than can be obtained by ICAP.

Additionally, if desired, the tester may use AAS for analysis of all

listed metals if the resulting in-stack method detection limits meet

the goal of the testing program. Mercury emissions can be measured,

alternatively, using EPA Method 101A of appendix B, 40 CFR part 61.

Method 101-A measures only Hg but it can be of special interest to

sources which need to measure both Hg and Mn emissions. Amendments to

Method 101A of appendix B of part 61 are being proposed to provide

consistency with Method 29.

II. Administrative Requirements

A. Public Hearing

A public hearing will be held, if requested, to discuss the

proposed rule in accordance with section 307(d)(5) of the Clean Air

Act. Persons wishing to make oral presentations should contact the EPA

at the address given in the ADDRESSES section of this preamble. Oral

presentations will be limited to 15 minutes each. Any member of the

public may file a written statement with the EPA before, during, or

within 30 days after the hearing. Written statements should be

addressed to the Air Docket address given in the ADDRESSES section of

this preamble.

A verbatim transcript of the hearing and written statements will be

available for public inspection and copying during normal working hours

at the EPA's Air Docket in Washington, DC (see ADDRESSES section of

this preamble).

B. Docket

The docket is an organized and complete file of all the information

submitted to or otherwise considered by the EPA in the development of

this proposed rulemaking. The principal purposes of the docket are: (1)

To allow interested parties to identify and locate documents so that

they can effectively participate in the rulemaking process, and (2) to

serve as the record in case of judicial review (except for interagency

review materials) [Section 307(d)(7)(A)].

C. Office of Management and Budget Review

1. Paperwork Reduction Act. This rule does not contain any

information collection requirements subject to the Office of Management

and Budget (OMB) review under the Paperwork Reduction Act, 44 U.S.C.

3501 et seq.

2. Executive Order 12866 review. Under Executive Order 12866 (58 FR

51735, October 4, 1993), the EPA must determine whether the regulatory

action is ``significant'' and therefore subject to the 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:

1. Have an annual effect on the economy of $100 million or more, or

adversely affect in a material way the economy, 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,

users 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, the EPA does not

consider this action to be significant because it does not involve any

of the above mentioned items.

D. Regulatory Flexibility Act Compliance

Pursuant to the provisions of 5 U.S.C. 601 et seq, I hereby certify

that this proposed rule, if promulgated, will not have an economic

impact on small entities because no additional costs will be incurred.

List of Subjects in 40 CFR Parts 60 and 61

Air pollution control, Arsenic, Asbestos, Beryllium, Cadmium, Lead,

Hazardous materials, Incorporation by reference, Intergovernmental

relations, Mercury, Municipal waste combustors, Reporting and

recordkeeping requirements, Sewage sludge incineration.

Statutory Authority. The statutory authority for this proposal

is provided by sections 101, 111, 112, 114, 116, 129, and 301 of the

Clean Air Act, as amended; 42 U.S.C., 7401, 7411, 7412, 7414, 7416,

7429, and 7601.

Dated: September 1, 1994.
