Standards of Performance for New Stationary Sources and Emission 
Guidelines for Existing Sources: Other Solid Waste Incineration Units: 
Reconsideration

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of reconsideration of final rule; request for public 
comment; notice of public hearing.

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

SUMMARY: On December 16, 2005, EPA published a final rule entitled, 
``Standards of Performance for New Stationary Sources and Emission 
Guidelines for Existing Sources: Other Solid Waste Incineration 
Units.'' Following that final action, the Administrator received a 
petition for reconsideration. In response to the petition, EPA is 
announcing its reconsideration of and requesting comment on whether 
sewage and sludge incinerators should be excluded from the other solid 
waste incineration units (OSWI) rules.

I. General Information

A. Does the reconsideration notice apply to me?

    Regulated Entities. This reconsideration proceeding potentially 
affects sewage sludge incinerators. Although there is not a specific 
North American Industrial Classification System (NAICS) code for sewage 
sludge incinerators, these units may be operated by municipalities or 
other entities and the following NAICS codes apply: Non-hazardous 
incinerators (NAICS 562213); sludge disposal sites (NAICS 562212); and 
sewage treatment facilities (NAICS 221320). The categories and entities 
regulated by the final OSWI rules are very small municipal waste 
combustion (VSMWC) units and institutional waste incineration (IWI) 
units. The final OSWI emission guidelines and new source performance 
standards (NSPS) affect the following categories of sources:

B. How do I obtain a copy of this document and other related 
information?

    Docket. The docket number for this action and the final OSWI new 
source performance standards (NSPS) (40 CFR part 60, subpart EEEE) and 
emission guidelines (40 CFR part 60, subpart FFFF) is Docket ID No. 
EPA-HQ-OAR-2003-0156.
    Worldwide Web (WWW). In addition to being available in the docket, 
electronic copies of the final rule and the notice of reconsideration 
are available on the WWW through the Technology Transfer Network Web 
site (TTN). Following signature, EPA posted a copy of the final rule on 
the TTN's policy and guidance page for newly proposed or promulgated 
rules at http://www.epa.gov/ttn/oarpg. The TTN provides information and 

technology exchange in various areas of air pollution control.

II. Background Information

    Section 129 of the Clean Air Act (CAA), entitled ``Solid Waste 
Combustion,'' requires EPA to develop and adopt NSPS and emission 
guidelines for solid waste incineration units pursuant to CAA section 
111. Section 111(b) of the CAA requires EPA to establish NSPS for new 
sources, and

[[Page 36728]]

CAA section 111(d) requires EPA to establish procedures for States to 
submit plans for implementing emission guidelines for existing sources. 
Congress specifically added section 129 to the CAA to address concerns 
about emissions from solid waste combustion units. Section 129(a)(1) of 
the CAA identifies five categories of solid waste incineration units:
    (1) Units with a capacity of greater than 250 tons per day (tpd) 
combusting municipal waste;
    (2) Units with a capacity equal to or less than 250 tpd combusting 
municipal waste;
    (3) Units combusting hospital, medical and infectious waste;
    (4) Units combusting commercial or industrial waste; and
    (5) Unspecified--other categories of solid waste incineration 
units.
    EPA previously developed regulations for each of the listed 
categories of solid waste incineration units except for the undefined 
``other categories of solid waste incineration units.'' On December 9, 
2004 (69 FR 71472), EPA proposed NSPS and emission guidelines for OSWI 
units. EPA received and considered public comments and promulgated 
final regulations for OSWI units on December 16, 2005.
    Following the promulgation of the final OSWI rule, EPA received a 
petition for reconsideration from the Sierra Club. The purpose of this 
notice is to initiate a process for responding to one issue raised in 
the petition.

III. Actions We Are Taking

    Today, we are granting reconsideration of and requesting comment on 
the sewage sludge incinerator issue, an issue raised in the petition 
for reconsideration. Generally, the Sierra Club contends that sewage 
sludge incinerators should be regulated as a type of OSWI under CAA 
section 129. Petitioner notes that the notice of proposal of the OSWI 
rule did not mention sewage sludge incinerators, and claims that there 
was no opportunity to comment on EPA's decision not to regulate sewage 
sludge incinerators under OSWI. Moreover, they argue that EPA's 
rationale was advanced for the first time in the final rule and 
supporting documents.
    EPA acknowledges that the OSWI proposal notice (69 FR 71472, 
December 9, 2004) did not specifically mention or request comment on 
whether sewage sludge incinerators should be regulated under the OSWI 
rules. EPA did publish notices on April 24, 2000, (65 FR 23459-01) and 
June 26, 2002, (67 FR 43113) in which EPA indicated that we had decided 
not to regulate sewage sludge incinerators as a category under CAA 
section 129 and listing it as an area source category to be regulated 
under CAA section 112(c)(3) and 112(k)(3). These notices; however, did 
not request public comment on whether sewage sludge incinerators should 
be regulated under section 129 or section 112. We have decided to grant 
reconsideration of this issue in the interest of ensuring full 
opportunity for comment. The issue is described in further detail 
below.
    Our final decision on reconsideration for all the other issues 
raised by petitioners, and for which we are not granting 
reconsideration today, will be issued no later than the date by which 
we take final action on the sewage sludge incinerator issue discussed 
in this notice. We are requesting public comment only on the sewage 
sludge incinerator issue identified in this notice. We will not respond 
to any comments addressing other aspects of the OSWI rule or any 
related rulemakings.

IV. Discussion of Issue for Reconsideration

    EPA acknowledges that earlier notices indicated that sewage sludge 
incinerators would be considered OSWI units (62 FR 1868, January 14, 
1997; 63 FR 66087, December 1, 1998). However, as we discussed in the 
preamble to the final OSWI rules and the response to comment document, 
later notices conveyed the fact we intended to regulate sewage sludge 
incinerators under section 112 of the CAA, not under section 129. As 
early as April 2000, EPA indicated that it no longer intended to 
regulate sewage sludge incinerators under CAA section 129:

    The Agency has decided not to regulate sewage sludge 
incinerators as a category under section 129 of the Clean Air Act. * 
* * The Agency believes that sewage sludge generated by publicly-
owned treatment works (POTWs) and combusted in SSI is ``solid 
waste.'' However, this sludge is from a municipal source, and not 
from ``commercial or industrial establishments or the general 
public.'' Therefore, SSIs that combust this sludge are not ``solid 
waste incineration units'' and section 129 does not apply to them. 
Virtually all of the SSIs that would be candidates for regulation 
combust sludge from POTWs and, thus are not covered under section 
129.

Unified Agenda, (65 FR 23459-01, April 24, 2000).
    EPA's intent to regulate these sources under CAA section 112 was 
also made clear when sewage sludge incinerators were included as an 
additional area source category listed pursuant to CAA sections 
112(c)(3) and 112(k)(3)(B)(ii) (67 FR 43113, June 26, 2002). In 
addition, in previous regulatory activities, EPA was unable to identify 
any sewage sludge incinerators that were major sources (see 67 FR 6521, 
February 12, 2002). As discussed fully in the preamble to the final 
OSWI rules and the supporting response to comment document, the 
language of CAA section 129(h) makes clear the Congressional intent for 
CAA regulations under section 129 or section 112 to be mutually 
exclusive. Accordingly, source categories regulated by CAA section 112 
may not also be subject to a CAA section 129 regulation.
    However, we acknowledge that neither the April 2000 nor the June 
2002 notice was a final regulatory action, and that no opportunity for 
public comment was available following either publication. Furthermore, 
as we did not discuss our intent to regulate sewage sludge incinerators 
under CAA section 112 in the proposed OSWI rules notice, we accept that 
we have not offered opportunity for comment on this issue. Therefore, 
we are granting reconsideration of, and requesting comment on, the 
issue of excluding sewage sludge incinerators from regulation under CAA 
section 129 under the OSWI rules.

V. 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 determine whether the regulatory action is ``significant'' and; 
therefore, subject to review by OMB 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 
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, 
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.
    It has been determined that this notice of reconsideration is not a 
``significant regulatory action'' under the terms of

[[Page 36729]]

Executive Order 12866 and is therefore not subject to OMB review.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden. 
We are not proposing any new paperwork as part of today's notice. With 
this action, we are seeking public comments on an issue raised in a 
petition for reconsideration of the OSWI rule. The Office of Management 
and Budget has previously approved the information collection 
requirements contained in the existing regulations (40 CFR part 60, 
subparts EEEE and FFFF) under the provisions of the Paperwork Reduction 
Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2060-
0563 and EPA ICR No. 2163.02 for subpart EEEE, and OMB control number 
2060-0562 and EPA ICR No. 2164.02 for subpart FFFF. A copy of the OMB 
approved Information Collection Requests (ICR), may be obtained from 
Susan Auby, Collection Strategies Division, U.S. EPA (2822T), 1200 
Pennsylvania Avenue, NW., Washington, DC 20460, by e-mail at 
auby.susan@epa.gov, or by calling (202) 566-1672.

    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 in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act 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 businesses, small organizations, 
and small governmental jurisdictions.
    For purposes of assessing the impacts of the final rules on small 
entities, small entity is defined as follows:
    1. A small business that is an ultimate parent entity in the 
regulated industry that has a gross annual revenue less than $6.0 
million (this varies by industry category, ranging up to $10.5 million 
for North American Industrial Classification System (NAICS) code 562213 
(very small municipal waste combustors)), based on Small Business 
Administration's size standards;
    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; or
    3. A small organization that is any not-for-profit enterprise that 
is independently owned and operated and is not dominant in its field.
    After considering the economic impact of today's notice of 
reconsideration on small entities, I certify that this action will not 
have a significant economic impact on a substantial number of small 
entities. This action does not propose any changes to the final OSWI 
rule and will not impose any requirements on small entities. EPA has 
determined that it is not necessary to prepare a regulatory flexibility 
analysis in connection with this reconsideration notice.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act (UMRA) of 1995, Public 
Law 104-4, 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 by State, local, and Tribal governments, in 
the aggregate, or by the private sector, of $100 million or more in any 
one 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 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 EPA 
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, EPA 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's regulatory proposals with significant Federal 
intergovernmental mandates, and informing, educating, and advising 
small governments on compliance with the regulatory requirements.
    EPA has determined that this notice of reconsideration 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. We are not proposing 
to change the final OSWI rule. Thus, today's notice of reconsideration 
is not subject to the requirements of section 202 and 205 of the UMRA. 
In addition, EPA has determined that the notice of reconsideration 
contains no regulatory requirements that might significantly or 
uniquely affect small governments. Therefore, the notice of 
reconsideration is not subject to the requirements of section 203 of 
the UMRA.

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 States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among various levels of 
government.''
    This notice of reconsideration does not have Federalism 
implications. It will not 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, as specified in Executive Order 13132. 
The notice of reconsideration will not impose direct compliance costs 
on State or local governments, and will not

[[Page 36730]]

preempt State law. Thus, Executive Order 13132 does not apply to 
today's notice of reconsideration.

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.'' ``Policies that have Tribal 
implications'' is defined in the Executive Order to include regulations 
that have ``substantial direct effects on relationship between the 
Federal Government and the Indian tribes, or on the distribution of 
power and responsibilities between the Federal Government and Indian 
tribes.''
    This notice of reconsideration does not have Tribal implications, 
as specified in Executive Order 13175. It will not have substantial 
direct effects on Tribal governments, on the relationship between the 
Federal Government and Indian tribes, or on the distribution of power 
and responsibilities between the Federal Government and Indian tribes, 
as specified in Executive Order 13175. Thus, Executive Order 13175 does 
not apply to this notice of reconsideration.

G. Executive Order 13045: Protection of Children From Environmental 
Health 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, EPA 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 reasonably 
feasible alternatives EPA considered.
    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. This notice of 
reconsideration is not subject to Executive Order 13045 because it is 
not economically significant, and the original OSWI rules were based on 
technology performance and not on health and safety risks.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution or Use

    This notice of reconsideration is not subject to Executive Order 
13211, ``Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, and Use'' (66 FR 28355, May 22, 2001) 
because it is not a significant regulatory action under Executive Order 
12866.

I. National Technology Transfer Advancement Act

    CAA section 12(d) of the National Technology Transfer and 
Advancement Act (NTTAA) of 1995 (Pub. L. 104-113; 15 U.S.C. 272 note) 
directs EPA to use voluntary consensus 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., materials specifications, test methods, sampling 
procedures, business practices) developed or adopted by one or more 
voluntary consensus bodies. The NTTAA directs EPA to provide Congress, 
through annual reports to OMB, with explanations when an agency does 
not use available and applicable voluntary consensus standards.
    This notice of reconsideration does not involve technical 
standards. EPA's compliance with section 12(d) of the NTTAA has been 
addressed in the preamble of the underlying final OSWI rule. (70 FR 
74891, December 16, 2005)
