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 new source performance

standards (NSPS) that control a designated pollutant, EPA establishes

EG 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 EG for that source category as well as 40

CFR part 60, subpart B (40 CFR 60.23 through 60.26).

On March 12, 1996, EPA promulgated NSPS for new MSW landfills at 40

CFR part 60, subpart WWW (Standards of Performance for Municipal Solid

Waste Landfills) and EG for existing MSW landfills at 40 CFR part 60,

subpart Cc (Emission Guidelines and Compliance Times for Municipal

Solid Waste Landfills) (see 61 FR 9905). The pollutants regulated by

the NSPS and EG are MSW landfill emissions, which contain a mixture of

volatile organic compounds (VOC), other organic compounds, methane, and

HAPs. VOC emissions 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 (NMOC) 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 60.32c) for which construction,

reconstruction or modification was commenced before May 30, 1991.

Pursuant to 40 CFR 60.23(a), States were required within nine

months after promulgation of subpart Cc (by December 12, 1996) to

submit either a plan to implement and enforce the EG or, if there are

no existing MSW landfills subject to the EG in the State, a negative

declaration letter.

EPA published a direct final rulemaking on June 16, 1998, in which

EPA amended 40 CFR part 60, subpart Cc (and subpart WWW), to add

clarifying language, make editorial amendments, and to correct

typographical errors (see 63 FR 32743). EPA published additional

technical amendments and corrections on February 24, 1999 (see 64 FR

9258). These amendments did not change the submittal date or the

requirements for State plans for existing MSW landfills.

On June 3, 1998, NDEP submitted to EPA the Nevada State Plan for

implementing the MSW landfill EG. NDEP submitted a technical revision

to the Nevada State Plan on May 21, 1999.

The Nevada State Plan does not apply to landfills in the two

counties that are not under the jurisdiction of the NDEP: Clark and

Washoe. Washoe County submitted a negative declaration letter on May 7,

1997 certifying that there are no existing MSW landfills that are

subject to the control requirements of the emission guidelines within

the County. Clark County has affected existing landfills but has not

submitted its portion of the Nevada State Plan. Existing landfills in

Clark County will be subject to the requirements of the Federal Plan

upon its promulgation until EPA receives and approves Clark County's

portion of the Nevada State Plan.

The following provides a brief discussion of the requirements for

an approvable State plan for existing MSW landfills and EPA's review of

the Nevada State Plan with respect to those requirements. A detailed

discussion of the State Plan and EPA's evaluation can be found in the

Technical Support Document for the Nevada Plan (8/99).

II. Review of the Nevada MSW Landfill Plan

EPA has reviewed the Nevada section 111(d) plan for existing MSW

landfills against the requirements of 40 CFR part 60, subparts B and

Cc, as follows:

A. Identification of Enforceable State Mechanism for Implementing the

EG

Subpart B at 40 CFR 60.24(a) requires that the section 111(d) plan

include emissions standards, defined in 40 CFR 60.21(f) as ``a legally

enforceable regulation setting forth an allowable rate of emissions

into the atmosphere, or prescribing equipment specifications for

control of air pollution emissions.'' The Nevada State Plan uses the

following State regulation as the enforceable mechanism: Nevada

Administrative Code (NAC) 445B.383 ``Municipal Solid Waste Landfills,''

as amended on April 9, 1999 by the Nevada State Environmental

Commission (SEC). This State regulation controls air emissions from

existing MSW landfills in the NDEP's jurisdiction.1 Thus,

Nevada has met the requirement of 40 CFR 60.24(a) to have legally

enforceable emission standards.

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

\1\ The Air Quality Bureau of NDEP has jurisdiction over the

landfills within the State of Nevada, excluding the landfills within

the counties of Clark and Washoe.

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

B. Demonstration of Legal Authority

Subpart B at 40 CFR 60.26 requires that the section 111(d) plan

demonstrate that the State has legal authority to adopt and implement

the emission standards and compliance schedules. The State has

demonstrated that the Nevada SEC has sufficient legal authority to

adopt rules governing MSW landfills and that the NDEP has sufficient

legal authority to enforce these rules and to develop and administer

this MSW landfill plan. The State statutes providing such authority are

sections 233B (Nevada Administrative Procedure Act) and 445B (Air

Pollution) of the Nevada Revised Statutes (NRS).

C. Inventory of Existing MSW Landfills in the State Affected by the

State Plan

Subpart B at 40 CFR 60.25(a) requires that the section 111(d) plan

include a complete source inventory of all designated facilities

regulated by the EG: existing MSW landfills (i.e., those MSW landfills

that constructed, reconstructed, or modified prior to May 30, 1991)

that have accepted waste since

[[Page 50766]]

November 8, 1987 or have additional capacity for future waste

deposition (see 40 CFR 60.32c(a)(1)). NDEP submitted a list of the

existing MSW landfills in Nevada as part of the State Plan.

D. Inventory of Emissions From Existing MSW Landfills in the State

Subpart B at 40 CFR 60.25(a) requires that the 111(d) plan include

an emissions inventory that estimates emissions of the designated

pollutant regulated by the EG: NMOC. NDEP has submitted an estimate of

annual NMOC emissions from the landfills in the source inventory as

part of the State Plan. NDEP used the procedures in 40 CFR 60.754 to

estimate the NMOC emissions.

E. Emission Standards for MSW Landfills

Subpart B at 40 CFR 60.24(c) specifies that the State plan must

include emission standards that are no less stringent than the EG

(except as specified in 40 CFR 60.24(f) which allows for less stringent

emission standards on a case-by-case basis if certain conditions are

met). The State regulation, NAC 445B.383, contains the emission

standards that are in subpart Cc. Thus, Nevada's State Plan complies

with this requirement.

F. A Process for State Review and Approval of Site-Specific Gas

Collection and Control System Design Plans

Subpart Cc at 40 CFR 60.33c(b) requires State plans to include a

process for State review and approval of site-specific design plans for

required gas collection and control systems. The process for NDEP

review and approval of site-specific gas collection and control systems

is specified in the State Plan. Thus, Nevada's section 111(d) plan

adequately addresses this requirement.

G. Compliance Schedules

The State's section 111(d) plan must include a compliance schedule

that owners and operators of affected MSW landfills must meet in

complying with the requirements of the plan. Subpart Cc at 40 CFR

60.36c provides that planning, awarding of contracts, and installation

of air emission collection and control equipment capable of meeting the

EG must be accomplished within 30 months of the date on which the NMOC

emission rate equals or exceeds 50 megagrams per year. The State

regulation, NAC 445B.383, contains the same compliance schedule as

subpart Cc.

H. Testing, Monitoring, Recordkeeping and Reporting Requirements

Subpart Cc at 40 CFR 60.34c specifies the testing and monitoring

provisions that State plans must include (60.34c specifically refers to

the requirements found in 40 CFR 60.754 to 60.756), and 40 CFR 60.35c

specifies the reporting and recordkeeping requirements (60.35c refers

to the requirements found in 40 CFR 60.757 and 60.758). The Nevada

landfill regulation incorporates by reference the requirements found in

40 CFR 60.754 to 60.758. Thus, the State Plan satisfies the

requirements of 40 CFR 60.34c and 60.35c.

I. A Record of Public Hearings on the State Plan

Subpart B at 40 CFR 60.23 contains the requirements for public

hearings that must be met by the State in adopting a section 111(d)

plan. NDEP included documents in its plan submittal demonstrating that

these requirements, as well as the State's administrative procedures,

were complied with in adopting the State landfill regulation and in

developing the State Plan. Therefore, EPA finds that Nevada has met

this requirement.

J. Submittal of Annual State Progress Reports to EPA

Subpart B at 40 CFR 60.25(e) and (f) requires States to submit to

EPA annual reports on the progress of plan enforcement. Nevada

committed in its section 111(d) plan to submit annual progress reports

to EPA. The first progress report will be submitted by the State one

year after EPA approval of the State Plan. Therefore, EPA finds that

Nevada has adequately met this requirement.

In summary, EPA finds that the Nevada State Plan meets all of the

requirements applicable to such plans in 40 CFR part 60, subparts B and

Cc.

III. Final Action

Based on the rationale discussed above, EPA is approving the State

of Nevada section 111(d) plan for the control of landfill gas emissions

from existing MSW landfills.2 As provided by 40 CFR

60.28(c), any revisions to the Nevada State Plan or associated

regulations will not be considered part of the applicable plan until

submitted by the NDEP 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.

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

\2\ The State did not submit evidence of authority to regulate

existing MSW landfills in Indian Country; therefore, EPA is not

approving this Plan as it relates to those sources.

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

The EPA is publishing this rule without prior proposal because the

Agency views this as a noncontroversial action and anticipates no

adverse comments. However, in the proposed rules section of this

Federal Register publication, EPA is publishing a separate document

that will serve as the proposal to approve the 111(d) plan should

relevant adverse or critical comments be filed. This rule will be

effective November 19, 1999 without further notice unless the Agency

receives relevant adverse comments by October 20, 1999.

If EPA receives such comments, then EPA will publish a document

withdrawing the final rule and informing the public that the rule did

not take effect. All public comments received will be addressed in a

subsequent final rule based on the proposed rule. EPA will not

institute a second comment period on this action. Any parties

interested in commenting 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 November 19, 1999 and no further action will be

taken on the proposed rule.

Nothing in this action should be construed as permitting or

allowing or establishing a precedent for any future request for

revision to any section 111(d) plan. Each request for revision to the

section 111(d) 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 review under Executive Order 12866, entitled

``Regulatory Planning and Review.''

B. Executive Order 12875

Under Executive Order 12875, EPA may not issue a regulation that is

not required by statute and that creates a mandate upon a state, local,

or tribal government, unless the Federal government provides the funds

necessary to pay the direct compliance costs incurred by those

governments. If EPA complies by consulting, Executive Order 12875

requires EPA to provide to the Office of Management and Budget a

description of the extent of EPA's prior consultation with

representatives of affected state, local, and tribal governments, the

nature of their

[[Page 50767]]

concerns, copies of written communications from the governments, and a

statement supporting the need to issue the regulation. In addition,

Executive Order 12875 requires EPA to develop an effective process

permitting elected officials and other representatives of state, local,

and tribal governments ``to provide meaningful and timely input in the

development of regulatory proposals containing significant unfunded

mandates.'' Today's rule does not create a mandate on state, local or

tribal governments. The rule does not impose any enforceable duties on

these entities. Accordingly, the requirements of section 1(a) of

Executive Order 12875 do not apply to this rule.

C. Executive Order 13045

Protection of Children from Environmental Health Risks and Safety

Risks (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 reasonably feasible

alternatives considered by the Agency.

This rule is not subject to Executive Order 13045 because it does

not involve decisions intended to mitigate environmental health or

safety risks.

D. Executive Order 13084

Under Executive Order 13084, EPA may not issue a regulation that is

not required by statute, that significantly affects or uniquely affects

the communities of Indian tribal governments, and that imposes

substantial direct compliance costs on those communities, unless the

Federal government provides the funds necessary to pay the direct

compliance costs incurred by the tribal governments. If EPA complies by

consulting, Executive Order 13084 requires EPA to provide to the Office

of Management and Budget, in a separately identified section of the

preamble to the rule, a description of the extent of EPA's prior

consultation with representatives of affected tribal governments, a

summary of the nature of their concerns, and a statement supporting the

need to issue the regulation. In addition, Executive Order 13084

requires EPA to develop an effective process permitting elected and

other representatives of Indian tribal governments ``to provide

meaningful and timely input in the development of regulatory policies

on matters that significantly or uniquely affect their communities.''

Today's rule does not significantly or uniquely affect the

communities of Indian tribal governments. This action does not involve

or impose any requirements that affect Indian Tribes. Accordingly, the

requirements of section 3(b) of Executive Order 13084 do not apply to

this rule.

E. Regulatory Flexibility

The Regulatory Flexibility Act (RFA) generally requires an agency

to conduct a regulatory flexibility analysis of any rule subject to

notice and comment rulemaking requirements 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 not-for-profit enterprises, and small governmental

jurisdictions. This final rule will not have a significant impact on a

substantial number of small entities because State Plan approvals under

section 111(d) of the Clean Air 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 create any

new requirements, I certify that this action will not have a

significant economic impact on a substantial number of small entities.

Moreover, due to the nature of the Federal-State relationship under the

Clean Air Act, preparation of flexibility analysis would constitute

Federal inquiry into the economic reasonableness of state action. The

Clean Air Act forbids EPA to base its actions concerning State Plans on

such grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66

(1976); 42 U.S.C. 7410(a)(2).

F. Disclaimer Language Approving State Plans in Audit Law States

Nothing in this action should be construed as making any

determination or expressing any position regarding Nevada's audit

privilege and penalty immunity law (NRS Chapter 445C.010-.120) or its

impact upon any approved State Plan, including the plan at issue here.

The action taken herein does not express or imply any viewpoint on the

question of whether there are legal deficiencies in this or any other

Clean Air Act program resulting from the effect of Nevada's audit

privilege and immunity law. A state audit privilege and immunity law

can affect only state enforcement and cannot have any impact on federal

enforcement authorities. EPA may at any time invoke its authority under

the Clean Air Act, including, for example, sections 113, 167, 205, 211

or 213, to enforce the requirements or prohibitions of the State Plan,

independently of any state enforcement effort. In addition, citizen

enforcement under section 304 of the Clean Air Act is likewise

unaffected by a state audit privilege or immunity law.

G. 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

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.

H. Submission to Congress and the Comptroller General

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the

Small Business Regulatory Enforcement Fairness Act of 1996, generally

provides that before a rule may take effect, the agency promulgating

the rule must submit a rule report, which includes a copy of the rule,

to each House of the Congress and to the Comptroller General of the

United States. EPA will submit 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 United States prior

to publication of the rule in the Federal Register. This rule is not a

``major rule'' as defined by 5 U.S.C. 804(2).

[[Page 50768]]

I. 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 November 19, 1999. 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 may 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).)
