National Emission Standards for Hazardous Air Pollutants 

for Stationary Combustion Turbines

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: On August 29, 2003, EPA promulgated final national emission 

standards for hazardous air pollutants (NESHAP) for stationary combustion 

turbines. As part of the NESHAP, EPA established eight subcategories of 

stationary combustion turbines. Elsewhere in this Federal Register, EPA is 

publishing a proposed rule to delete four of these subcategories from the source 

category list required by section 112(c)(1) of the Clean Air Act (CAA). The EPA 

has made an initial determination that the four subcategories satisfy the criteria 

for deletion from the source category list established by section 112(c)(9)(B).

In this companion action, EPA is proposing to stay the effectiveness of the 

combustion turbines NESHAP for new sources in the lean premix gas-fired 

turbines and diffusion flame gas-fired turbines subcategories, which are the two 

principal subcategories we are proposing to delist. This action is necessary to 

avoid wasteful and unwarranted expenditures on installation of emission controls 
2

which will not be required if the subcategories are delisted.

DATES: Comments. Written comments on the proposed rule 

must be received by EPA no later than [INSERT DATE 45 DAYS 

FROM PUBLICATION OF THE PROPOSED RULE IN THE FEDERAL 

REGISTER].

Public Hearing. A public hearing regarding the proposed 

rule will be held if requests to speak are received by the 

EPA on or before [INSERT DATE 7 DAYS FROM PUBLICATION OF THE

PROPOSED RULE IN THE FEDERAL REGISTER]. If requested, a

I. Description of the Proposed Rule

Elsewhere in today’s Federal Register, EPA is proposing 

a rule to amend the list of categories of sources that was 

developed pursuant to CAA section 112(c)(1). The EPA is 

proposing to delete four subcategories from the Combustion 

Turbines source category. Final MACT standards creating 

these subcategories was promulgated on August 29, 2003. The

standards will be published soon and will be codified at 40 

CFR part 63, subpart YYYY. The subcategories, as defined in 
11

40 CFR 63.6175, are: (1) lean premix gas-fired stationary 

combustion turbines (also referred to herein as “lean premix 

gas-fired turbines”), (2) diffusion flame gas-fired 

stationary combustion turbines (also referred to herein as 

“diffusion flame gas-fired turbines”), (3) emergency 

stationary combustion turbines, and 4) stationary combustion 

turbines located on the North Slope of Alaska.

The proposed rule to amend the source category list is 

being issued in part to respond to a petition submitted by 

the Gas Turbine Association (GTA) and in part upon the 

Administrator’s own motion. Petitions to remove a source 

category from the source category list are permitted under 

section 112(c)(9) of the CAA. The proposed rule to delete 

the four subcategories is based on an initial determination 

by EPA that the subcategories satisfy the substantive 

criteria for deletion set forth in section 112(c)(9)(B). 

The proposed rule to delete the subcategories that appears 

elsewhere in today’s Federal Register contains a detailed 

description of the technical basis for the initial 

determination.

Although EPA is proposing to delete from the source 

category list four subcategories established by the final 

MACT standards for Stationary Combustion Turbines, CAA 
12

section 112(d)(10) provides that the standards for the four

subcategories will take effect upon publication of the 

standards. All turbines in the lean premix gas-fired 

turbine and the diffusion flame gas-fired turbine

subcategories which were constructed or reconstructed after 

January 14, 2003, will then be required to comply 

immediately with the emission standards for new sources. 

This may cause some sources in the two subcategories to make 

immediate expenditures on installation and testing of 

emission controls, even though such controls will not be 

required if we adopt a final rule to delete these 

subcategories. In view of our initial determination that 

the statutory criteria for delisting have been met for all 

sources in the four subcategories, we consider it 

inappropriate and contrary to statutory intent to mandate 

such expenditures until after a final determination has been

made whether or not these subcategories should be delisted. 

Such expenditures would be wasteful and unwarranted if we 

take final action to delist these subcategories. Moreover, 

if we take final action to delist the subcategories, sources 

constructed or reconstructed while the rulemaking to delist 

is pending would bear a regulatory burden not placed on 

identical sources constructed or reconstructed thereafter. 

Accordingly, we are proposing this rule to stay the 
13

effectiveness of the emission standards for new sources for 

the lean premix gas-fired turbine and diffusion flame gasfired turbine subcategories during the pendency of the 

rulemaking to delete these subcategories.

We are mindful that there would be no need to stay the 

effectiveness of the standards for new sources in the two 

subcategories if a rulemaking to delist the affected sources

had been completed before promulgation of the final MACT 

standards for combustion turbines. However, we note that 

the GTA petition was not submitted until quite late in the regulatory process. 

Moreover, we generally do not make a definite determination concerning the 

characteristics of subcategories until promulgation of final MACT standards. 

In these circumstances, we do not believe it would be fair to make certain 

affected sources bear the burden of a delay in our determination that a 

subcategory meets the statutory criteria for delisting.

The proposed stay is consistent with the precedents we 

have established in similar circumstances in the past. In 

1991, we issued a final rule staying the effective date of 

the National Emission Standards for Radionuclear Emissions 

from Federal Facilities Other Than Nuclear Regulatory 

Commission Licenses and not covered by Subpart H (40 CFR 

part 61, Subpart H)(40 CFR part 61, Subpart I) for 

commercial nuclear power reactors during the pendency of 
14

another rulemaking to rescind the standards for those

facilities (56 FR 37158 August 5, 1991). The rescission was 

authorized by section 112(d)(9) of the CAA (the “Simpson 

amendment”), which provides that we may decline to regulate 

Nuclear Regulatory Commission (NRC) licensees under CAA 

section 112 if the Administrator determines that the 

regulatory program established by the NRC for a category or 

subcategory provides an ample margin of safety to protect 

the public health. We had made an initial determination 

that the NRC program for commercial nuclear power reactors 

met this test, and we reasoned that “it would frustrate the 

evident purpose of Section 112(d)(9) if EPA were to permit 

Subpart I to take effect for this subcategory during the 

pendency of the rulemaking on rescission” (56 FR 37159). 

That action was not challenged.

In 1995, we acted to provide another type of interim 

relief during a delisting rulemaking. We suspended the 

listing of caprolactam, during a rulemaking to delete 

caprolactam from the list of HAP established by CAA section 

112(b)(1) for purposes of determining the applicability of 

title V permitting requirements (60 FR 081, September 18, 

1995). We based that action on our determination that 

“retention, during the rulemaking to delist caprolactam, of 

permit application requirements which will no longer exist 
15

after the delisting process has been completed would result 

in unnecessary private and public expenditures on 

preparation, submission, and processing of such 

applications, and would yield no environmental benefits” (60

FR 084-85). That interim relief action also was not 

challenged.

We are proposing to stay the effectiveness of the 

combustion turbines emission standards for new sources in 

the lean premix gas-fired turbines and the diffusion flame 

gas-fired turbines subcategories, but only during the 

pendency of the rulemaking to delist the subcategories. It 

is not our intention by staying the effectiveness of the 

standards to change the definition of new sources within 

these subcategories or to alter the status of any individual 

source. If the subcategories are not ultimately delisted, 

the stay will be lifted, and all sources in the

subcategories constructed or reconstructed after January 14,

2003 will then be subject to the final standards. The

sources will then be given the same time to make the 

requisite demonstration of compliance they would have had if

there had been no stay.

II. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA must 
16

determine whether the regulatory action is “significant” and therefore subject to 

Office of Management and Budget (OMB) review and the requirements of the 

Executive Order. The Executive Order defines “significant regulatory action” as 

one that is likely to result in a rule that may:

(1) Have an annual effect on the economy of $100 million or more or 

adverse affect in a material way the economy, a sector to 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 obligation 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, it has been determined 

that the proposed action does not constitute a “significant regulatory action” and 

is, therefore, not subject to OMB review.

B. Paperwork Reduction Act

This action does not impose an information collection burden under the 

provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The 

proposed action will stay the effectiveness of the combustion turbines NESHAP 

for new sources in the lean premix gas-fired turbines and diffusion flame gas-
17

fired turbines subcategories until a conclusion is reached regarding deletion and 

therefore eliminate the need for information collection toward regulatory 

compliance under the CAA. Burden means the total time, effort, or financial 

resources expended by persons to generate, maintain, retain, or disclose or

provide information to or for a Federal agency. This includes the time needed to 

review instructions; develop, acquire, install, and utilize technology and systems 

for the purposes of collecting, validating, and verifying information, processing 

and maintaining information, and disclosing and providing information; adjust the 

existing ways to comply with any previously applicable instructions and 

requirements; train personnel to be able to respond to a collection of information; 

search data sources; complete and review the collection of information; and 

transmit or otherwise disclose the information. An Agency may not conduct or 

sponsor, and a person is not required to respond to a collection of information 

unless it displays a currently valid OMB control number. The OMB control 

numbers for EPA’s regulations are listed in 40 CFR part 9 and 48 CFR chapter 

15.

C. Regulatory Flexibility Act (RFA)

The RFA generally requires an agency to prepare a regulatory flexibility 

analysis of any rule subject to notice and comment rulemaking requirements 

under the Administrative Procedure Act or any other statute unless the agency 

certifies that the rule will not have a significant economic impact on a substantial 

number of small entities. Small entities include small business, small 
18

organizations, and small governmental jurisdictions. For the purposes of 

assessing the impacts of today’s proposed rule on small entities, small entity is 

defined as: (1) a small business that meets the definitions for small business 

based on the Small Business Association (SBA) size standards which, for this 

proposed action, can include manufacturing (NAICS 3999-03) and air 

transportation (NAICS 4522-98 and 4512-98) operations that employ less 1,000 

people and engineering services (NAICS 8711-98) operations that earn less than 

$20 million annually; (2) a small governmental jurisdiction that is a government of 

a city, county, town, school district or special district with a population of less 

than 50,000; and (3) a small organization that is any not-for-profit enterprise 

which is independently owned and operated and is not dominant in its field.

After considering the economic impact of today’s proposed rule on small 

entities, I certify that this proposed action will not have a significant economic 

impact on a substantial number of small entities. In determining whether a rule 

has significant economic impact on a substantial number of small entities, the 

impact of concern is any significant adverse economic impact on small entities, 

since the primary purpose of the regulatory flexibility analysis is to identify and 

address regulatory alternatives “which minimize any significant economic impact 

of the proposed rule on small entities.” (5 U.S.C. 603 and 604). Thus, an 

agency may certify that a rule will not have a significant economic impact on a 

substantial number of small entities if the rule relieves regulatory burden, or 

otherwise has a positive economic effect on all of the small entities subject to the 
19

rule. The proposed rule will stay the effectiveness of the combustion turbines 

NESHAP for new sources in the lean premix gas-fired turbines and diffusion 

flame gas-fired turbines subcategories. This will stay the requirements to apply 

controls and will also stay associated operating, monitoring and reporting 

requirements. These burdens will be permanently lifted if EPA ultimately 

removes the four source categories from the stationary combustion turbine 

source category, and temporarily lifted if EPA does not ultimately delist the 

subcategories. We have, therefore, concluded that today’s proposed rule will 

relieve regulatory burden for all small entities. We continue to be interested in 

the potential impacts of the proposed rule on small entities and welcome 

comments on issues related to such impacts.

D. Unfunded Mandates Reform Act

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 

Law 1044, establishes requirements for Federal agencies to assess the effects 

of their regulatory actions on State, local, and tribal governments and the private 

sector. Under section 202 of the UMRA, EPA generally must prepare a written 

statement, including a cost-benefit analysis, for proposed and final rules with 

“Federal mandates” that may result in expenditures to State, local, and tribal 

governments, in the aggregate, or to the private sector, of $100 million or more in 

any 1 year. Before promulgating an EPA rule for which a written statement is 

needed, section 205 of the UMRA generally requires EPA to identify and 

consider a reasonable number of regulatory alternatives and adopt the least 
20

costly, most cost-effective or least burdensome alternative that achieves the 

objectives of the rule. The provisions of section 205 do not apply when they are 

inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an 

alternative other than the least costly, most cost-effective or least burdensome 

alternative if the Administrator publishes with the final rule an explanation why 

that alternative was not adopted. Before EPA establishes any regulatory 

requirements that may significantly or uniquely affect small governments, 

including tribal governments, it must have developed under section 203 of the 

UMRA a small government agency plan. The plan must provide for notifying 

potentially affected small governments, enabling officials of affected small 

governments to have meaningful and timely input in the development of EPA 

regulatory proposals with significant Federal intergovernmental mandates, and 

informing, educating, and advising small governments on compliance with the 

regulatory requirements.

Today’s proposed rule contains no Federal mandates for State, local, or 

tribal governments or the private sector. The proposed rule imposes no 

enforceable duty on any State, local or tribal governments or the private sector. 

In any event, EPA has determined that the proposed rule does not contain a 

Federal mandate that may result in expenditures of $100 million or more for 

State, local, and tribal governments, in the aggregate, or the private sector in any 

one year. Thus, today’s proposed rule is not subject to the requirements of 

sections 202 and 205 of the UMRA.
21

E. Executive Order 13132, Federalism

Executive Order 13132 (64 FR 43255, August 10, 1999) requires EPA to 

develop an accountable process to ensure “meaningful and timely input by State 

and local officials in the development of regulatory policies that have federalism 

implications.” “Policies that have federalism implications” is defined in the 

Executive Order to include regulations that have “substantial direct effects on the 

States, on the relationship between the national government and the States, or 

on the distribution of power and responsibilities among the various levels of 

government.”

Under Executive Order 13132, EPA may not issue a regulation that has 

federalism implications, that imposes substantial direct compliance costs, and 

that is not required by statute, unless the Federal government provides the funds 

necessary to pay the direct compliance costs incurred by State and local 

governments, or EPA consults with State and local officials early in the process 

of developing the proposed regulation. The EPA also may not issue a regulation 

that has federalism implications and that preempts State law unless the Agency 

consults with State and local officials early in the process of developing the 

proposed regulation.

Today’s action proposes to stay the effectiveness of the combustion 

turbines NESHAP for new sources in the lean premix gas-fired turbines and 

diffusion flame gas-fired turbines subcategories. It does not impose any 

additional requirements on the States and does not affect the balance of power 
22

between the States and the Federal government. Thus, the requirements of 

section 6 of the Executive Order do not apply to the proposed rule.

F. Executive Order 13175, Consultation and Coordination with Indian Tribal 

Governments

Executive Order 13175, entitled “Consultation and Coordination with 

Indian Tribal Governments” (65 FR 67249, November 9, 2000), requires EPA to 

develop an accountable process to ensure “meaningful and timely input by tribal 

officials in the development of regulatory policies that have tribal implications.” 

The proposed rule does not have tribal implications, as specified in Executive 

Order 13175. The proposed action will stay the effectiveness of the combustion 

turbines NESHAP for new sources in the lean premix gas-fired turbines and 

diffusion flame gas-fired turbines subcategories. Executive Order 13175 does 

not apply to the proposed rule.

G. Executive Order 13045, Protection of Children from Environmental Health 

Risks and Safety Risks

Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any rule 

that: (1) is determined to be “economically significant” as defined under 

Executive Order 12866, and (2) concerns an environmental health or safety risk 

that EPA has reason to believe may have a disproportionate effect on children. 

If the regulatory action meets both criteria, the Agency must evaluate the 

environmental health or safety effects of the planned rule on children, and 

explain why the planned regulation is preferable to other potentially effective and 
23

reasonably feasible alternatives considered by the Agency.

The EPA interprets Executive Order 13045 as applying only to those 

regulatory actions that are based on health or safety risks, such that the analysis 

required under section 5-501 of the Executive Order has the potential to 

influence the regulation. The proposed rule is not subject to Executive Order 

13045 because it is not economically significant as defined in Executive Order 

12866, and because this action is not based on health or safety risks. Thus, 

Executive Order 13045 does not apply to this rule.

H. Executive Order 13211, Actions Concerning Regulations that Significantly 

Affect Energy Supply, Distribution, or Use

Executive Order 13211, “Actions Concerning Regulations that Significantly 

Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001), 

requires EPA to prepare and submit a Statement of Energy Effects to the 

Administrator of the Office of Information and Regulatory Affairs, Office of 

Management and Budget, for certain actions identified as “significant energy 

actions.” The proposed rule is not a “significant energy action” because it is not 

likely to have a significant adverse effect on the supply, distribution, or use of 

energy.

I. National Technology Transfer and Advancement Act

Section 112(d) of the National Technology Transfer and Advancement Act 

of 1995 (NTTAA), Public Law No. 104-113, section 12(d) 915 U.S.C. 272 note), 

directs all Federal 
24

agencies to use voluntary consensus standards instead of government-unique 

standards in their regulatory activities unless to do so would be inconsistent with 

applicable law or otherwise impractical. Voluntary consensus standards are 

technical standards (e.g., material specifications, test method, sampling and 

analytical procedures, business practices, etc.) that are developed or adopted by 

one or more voluntary consensus standards bodies. Examples of organizations 

generally regarded as voluntary consensus standards bodies include the 

American society for Testing and Materials (ASTM), the National Fire Protection 

Association (NFPA), and the Society of Automotive Engineers (SAE). The 

NTTAA requires Federal agencies like EPA to provide Congress, through OMB, 

with explanations when an agency decides not to use available and applicable 

voluntary consensus standards. The proposed rule does not involve technical 

standards. Therefore, EPA is not considering the use of any voluntary 

consensus standards.
