[UT001-0010a and UT001-0011a; FRL-5948-7]


Approval and Promulgation of State Plans for Designated 
Facilities and Pollutants; Utah; Control of Landfill Gas Emissions From 
Existing Municipal Solid Waste Landfills

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The EPA is approving the Utah plan and associated regulations 
for implementing the Municipal Solid Waste (MSW) Landfill Emission 
Guidelines at 40 CFR part 60, subpart Cc, which were required pursuant 
to section 111(d) of the Clean Air Act (Act). The State's plan was 
originally submitted to EPA on April 2, 1997 with revisions to the plan 
submitted on October 31, 1997, in accordance with the requirements for 
adoption and submittal of State plans for designated facilities in 40 
CFR part 60, subpart B. The State's plan establishes performance 
standards for existing MSW landfills and provides for the 
implementation and enforcement of those standards. EPA finds that 
Utah's plan for existing MSW landfills, as amended, adequately 
addresses all of the Federal requirements applicable to such plans.

DATES: This action is effective on March 16, 1998 unless adverse or 
critical comments are received in writing by February 13, 1998. If the 
effective date is delayed, timely notice will be published in the 
Federal Register.

ADDRESSES: Written comments on this action should be addressed to Vicki 
Stamper, 8P2-A, at the EPA Region VIII Office listed. Copies of the

SUPPLEMENTARY INFORMATION:

I. Background

    Under section 111(d) of the Act, EPA has established procedures 
whereby States submit plans to control certain existing sources of 
``designated pollutants.'' Designated pollutants are defined as 
pollutants for which a standard of performance for new sources applies 
under section 111, but which are not ``criteria pollutants'' (i.e., 
pollutants for which National Ambient Air Quality Standards (NAAQS) are 
set pursuant to sections 108 and 109 of the Act) or hazardous air 
pollutants (HAPs) regulated under section 112 of the Act. As required 
by section 111(d) of the Act, EPA established a process at 40 CFR part 
60, subpart B, which States must follow in adopting and submitting a 
section 111(d) plan. Whenever EPA promulgates a new source performance 
standard (NSPS) that controls a designated pollutant, EPA establishes 
emissions guidelines in accordance with 40 CFR 60.22 which contain 
information pertinent to the control of the designated pollutant from 
that NSPS source category (i.e., the ``designated facility'' as defined 
at 40 CFR 60.21(b)). Thus, a State's section 111(d) plan for a 
designated facility must comply with the emission guideline for that 
source

[[Page 2155]]

category as well as 40 CFR part 60, subpart B.
    On March 12, 1996, EPA published Emission Guidelines (EG) for 
existing MSW landfills at 40 CFR part 60, subpart Cc (40 CFR 60.30-c-
60.36c) and NSPS for new MSW Landfills at 40 CFR part 60, subpart WWW 
(40 CFR 60.750-60.759). (See 61 FR 9905-29.) The pollutant regulated by 
the NSPS and EG is MSW landfill emissions, which contain a mixture of 
volatile organic compounds (VOCs), other organic compounds, methane, 
and HAPs. VOC emissions can contribute to ozone formation which can 
result in adverse effects to human health and vegetation. The health 
effects of HAPs include cancer, respiratory irritation, and damage to 
the nervous system. Methane emissions contribute to global climate 
change and can result in fires or explosions when they accumulate in 
structures on or off the landfill site. To determine whether control is 
required, nonmethane organic compounds (NMOCs) are measured as a 
surrogate for MSW landfill emissions. Thus, NMOC is considered the 
designated pollutant. The designated facility which is subject to the 
EG is each existing MSW landfill (as defined in 40 CFR 60.31c) for 
which construction, reconstruction or modification was commenced before 
May 30, 1991.
    Pursuant to 40 CFR 60.23(a), States were required to either: (1) 
Submit a plan for the control of the designated pollutant to which the 
EG applies or (2) submit a negative declaration if there were no 
designated facilities in the State within nine months after publication 
of the EG, or by December 12, 1996.
    EPA has been involved in litigation over the requirements of the 
MSW landfill EG and NSPS since the summer of 1996. On November 13, 
1997, EPA issued a notice of proposed settlement in National Solid 
Wastes Management Association v. Browner, et al., No. 96-1152 (D.C. 
Cir.), in accordance with section 113(g) of the Act. (See 62 FR 60898.) 
It is important to note that the proposed settlement does not vacate or 
void the existing MSW landfill EG or NSPS. Accordingly, the currently-
promulgated MSW landfill EG was used as a basis for EPA's review of 
Utah's submittals.

II. Analysis of State's Submittals

    On April 2, 1997, the State of Utah submitted its plan and 
regulations (hereafter referred to as the ``State Plan'') for 
implementing EPA's MSW landfill EG. However, the State Plan did not 
adequately address all of the requirements of 40 CFR part 60, subparts 
B and Cc. Consequently, the State adopted amendments to the State Plan 
and submitted those amendments to EPA for approval on October 31, 1997. 
The Utah State Plan, as amended, includes the ``Utah State Plan for 
Implementation of Emission Controls for Existing Designated Facilities, 
Section I. Municipal Solid Waste Landfills,'' technical support 
documentation for the plan, and the State's implementing regulations in 
Utah Air Conservation Regulations (UACR) R307-20-2 and R307-21.
    Utah has incorporated by reference the NSPS regulations of 40 CFR 
part 60, subpart WWW, at UACR R307-21-3 with a few minor revisions to: 
make the rule apply to existing MSW landfills, ensure that the rules 
comply with the EG, reference the State's solid waste requirements for 
MSW landfills, and make other minor changes. The EG specifies 
essentially the same provisions that are in the NSPS, except that the 
EG requirements apply to existing MSW landfills. Utah has also adopted 
compliance deadlines in UACR 307-21-5 to comply with the compliance 
timelines of the EG and the increments of progress requirements of 40 
CFR part 60, subpart B. Thus, the State's regulations adequately 
address the requirements of the EG, including the required 
applicability, emission limitations, test methods and procedures, 
reporting and recordkeeping requirements, and compliance times. 
Specifically, Utah's regulation requires that existing MSW landfills 
that: (1) Accepted waste since November 8, 1987; (2) have a design 
capacity equal to or greater than 2.5 million megagrams (Mg) or 2.5 
million m\3\; and (3) have a NMOC emission rate, calculated in 
accordance with the procedures of 40 CFR 60.754, equal to or greater 
than 50 Mg/year to install a gas collection and control system meeting 
the requirements of 40 CFR 60.752 within thirty months from the date of 
EPA approval of the State Plan (or, for those existing MSW landfills 
whose NMOC emission rate is less than 50 Mg/yr on the date EPA approves 
the State Plan, within thirty months after the landfill's NMOC emission 
rate equals or exceeds 50 Mg/yr).
    The State Plan also includes documentation showing that all 
requirements of 40 CFR part 60, subpart B have been met. Specifically, 
the State Plan includes a demonstration of legal authority to adopt and 
implement the plan, an emissions inventory, increments of progress 
compliance deadlines, a commitment to submit to EPA annual State 
progress reports on plan implementation and enforcement, and 
documentation that the State addressed the public participation 
requirements of 40 CFR part 60.23 for both the original submittal of 
April 2, 1997 and the amendments to the State Plan submitted on October 
31, 1997. In addition, as stated above, the State has adopted emission 
standards and compliance schedules into an enforceable State regulation 
that is no less stringent than the EG.
    Consequently, EPA finds that the State Plan, as amended, meets all 
of the requirements applicable to such plans in 40 CFR part 60, 
subparts B and Cc. The State did not, however, submit evidence of 
authority to regulate existing MSW landfills in Indian Country. 
Therefore, EPA is not approving this State Plan as it relates to those 
sources.
    More detailed information on the requirements for an approvable 
plan and Utah's submittals can be found in the Technical Support 
Document (TSD) accompanying this notice, which is available upon 
request.

III. Final Action

    Based on the rationale discussed above and in further detail in the 
TSD associated with this action, EPA is approving Utah's section 111(d) 
plan and associated regulations, as submitted on April 2, 1997 and on 
October 31, 1997, for the control of landfill gas from existing MSW 
landfills, except for those existing MSW landfills located in Indian 
Country. As provided by 40 CFR 60.28(c), any revisions to Utah's State 
Plan or associated regulations will not be considered part of the 
applicable plan until submitted by the State in accordance with 40 CFR 
60.28 (a) or (b), as applicable, and until approved by EPA in 
accordance with 40 CFR part 60, subpart B.
    EPA is publishing this action without prior proposal because the 
Agency views this as a noncontroversial amendment and anticipates no 
adverse comments. However, in a separate document in this Federal 
Register publication, EPA is proposing to approve the State Plan should 
adverse or critical comments be filed. This action will be effective 
March 16, 1998 unless, by February 13, 1998, adverse or critical 
comments are received.
    If EPA receives such comments, this action will be withdrawn before 
the effective date by publishing a subsequent document that will 
withdraw the final action. All public comments received will then be 
addressed in a subsequent final rule based on this action serving as a 
proposed rule. EPA will not institute a second comment period on this 
action. Any parties interested in commenting

[[Page 2156]]

on this action should do so at this time. If no such comments are 
received, the public is advised that this action will be effective on 
March 16, 1998.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any State Plan. Each request for revision to a State Plan 
shall be considered separately in light of specific technical, 
economic, and environmental factors and in relation to relevant 
statutory and regulatory requirements.

IV. Administrative Requirements

A. Executive Order 12866

    The Office of Management and Budget (OMB) has exempted this 
regulatory action from E.O. 12866 review.

B. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act, 5 U.S.C. 600, et seq., EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities. 5 U.S.C. 603 and 604. 
Alternatively, EPA may certify that the rule will not have a 
significant economic impact on a substantial number of small entities. 
Small entities include small businesses, small not-for-profit 
enterprises, and government entities with jurisdiction over populations 
of less than 50,000.
    State Plan approvals under section 111 of the Act do not create any 
new requirements, but simply approve requirements that the State is 
already imposing. Therefore, because the Federal State Plan approval 
does not impose any new requirements, I certify that it does not have a 
significant impact on small entities affected. Moreover, due to the 
nature of the Federal-state relationship under the Act, preparation of 
a regulatory flexibility analysis would constitute Federal inquiry into 
the economic reasonableness of state action. The Act forbids EPA to 
base its actions concerning State Plans on such grounds. Union Electric 
Co. v. U.S. E.P.A., 427 U.S. 246, 256-66 (1976); 42 U.S.C. 7410(a)(2).

C. Unfunded Mandates

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to State, local, or tribal governments in the aggregate; or to 
the private sector, of $100 million or more. Under section 205, EPA 
must select the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires EPA to establish a plan 
for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    EPA has determined that the approval action promulgated does not 
include a Federal mandate that may result in estimated costs of $100 
million or more to either State, local, or tribal governments in the 
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new 
requirements. Accordingly, no additional costs to State, local, or 
tribal governments, or to the private sector, result from this action.

D. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, EPA submitted a report 
containing this rule and other required information to the U.S. Senate, 
the U.S. House of Representatives, and the Comptroller General of the 
General Accounting Office prior to publication of this rule in today's 
Federal Register. This rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

E. Petitions for Judicial Review

    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by March 16, 1998. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule for the purposes of judicial 
review nor does it extend the time within which a petition for judicial 
review must be filed, and shall not postpone the effectiveness of such 
rule or action. This action may not be challenged later in proceedings 
to enforce its requirements (see section 307(b)(2)).
