40 CFR Part 62
[EPA-R09-OAR-2007-1150; FRL-8505-4]
Disapproval of Plan of Nevada: Clean Air Mercury Rule
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to disapprove the State Plan submitted by
Nevada on November 15, 2006. The plan is intended to address the
requirements of EPA's Clean Air Mercury Rule (CAMR), promulgated on May
18, 2005 and subsequently revised on June 9, 2006. EPA is proposing to
determine that the submitted Nevada State Plan does not meet certain
CAMR requirements and, therefore, must be disapproved.
CAMR requires States to regulate emissions of mercury (Hg) from
large coal-fired electric generating units (EGUs). CAMR establishes
State budgets for annual EGU Hg emissions and requires States to submit
State Plans that ensure that annual in-state EGU Hg emissions will not
exceed the applicable State budget. States have the flexibility to
choose which control measures to adopt to achieve the budgets,
including participating in the EPA-administered CAMR cap-and-trade
program. In the State Plan that EPA is proposing to disapprove, Nevada
has chosen to meet CAMR requirements by participating in the EPA-
administered CAMR cap-and-trade program addressing Hg emissions.
However, Nevada's plan does not meet the mandatory timing requirements
for allowance allocations, and differs substantively from certain
required provisions of EPA's model rule (including the provision
requiring unrestricted allowance transfer and trading).

I. What Action Is EPA Proposing To Take?
EPA is proposing to disapprove Nevada's State Plan, submitted on
November 15, 2006, because Nevada's submitted State Plan does not meet
certain CAMR requirements necessary for participation in the EPA-
administered CAMR cap-and-trade program. Nevada's plan requires EGUs to
participate in the EPA-administered CAMR cap-and-trade program
addressing Hg emissions. However, the State Plan does not meet the
mandatory allocation timing requirements under 40 CFR
60.24(h)(6)(ii)(C) and (D) and differs substantively from certain
required provisions of EPA's model rule at 40 CFR part 60, subpart HHHH
(including the requirement to provide for unrestricted allowance
transfer and trading). Furthermore, as an allowance system that does
not meet the above requirements, Nevada's State Plan fails to state
that Hg allowances issued under the Nevada CAMR program will not
qualify as Hg allowances under the EPA-administered cap-and-trade
program as required by 40 CFR 60.24(h)(7). Consequently, EPA is
proposing to determine that the State Plan does not meet the applicable
requirements of CAMR and to disapprove the plan on that basis.
II. What Is the Regulatory History of CAMR?
CAMR was published by EPA on May 18, 2005 (70 FR 28606, ``Standards
of Performance for New and Existing Stationary Sources: Electric
Utility Steam Generating Units; Final Rule''). In this rule, acting
pursuant to its authority under section 111(d) of the Clean Air Act
(CAA), 42 U.S.C. 7411(d), EPA required that all States meet Statewide
annual budgets limiting Hg emissions from large coal-fired electric
generating units (i.e., EGUs, as defined in 40 CFR 60.24(h)(8)). EPA
further required all States to submit State Plans that include control
measures that ensure that total, annual Hg emissions from new and
existing EGUs do not exceed the applicable Statewide annual EGU Hg
emissions budget. Under CAMR, States may implement these emissions
limitations either by participating in the EPA-administered CAMR cap-
and-trade program or by adopting other effective and enforceable
control measures.
CAMR explains what must be included in State Plans and sets a
deadline for submittal to EPA by November 17, 2006. Under 40 CFR
60.27(b), the Administrator will approve or disapprove the submitted
State Plans. The purpose of this action is to propose disapproval of
Nevada's CAMR State Plan.
III. What Are the General Requirements of CAMR State Plans?
CAMR establishes Statewide annual EGU Hg emission budgets
implemented in two phases. The first phase starts in 2010 and continues
through 2017. The second phase starts in 2018 and continues thereafter.
CAMR requires States to implement the budgets by either: (1) Requiring
EGUs to participate in the EPA-administered CAMR cap-and-trade program;
or (2) adopting other EGU control measures of the respective State's
choosing and demonstrating that such control measures will result in
compliance with the applicable State annual EGU Hg emissions budget.
Each State Plan must require EGUs to comply with the monitoring,
recordkeeping, and reporting provisions of 40 CFR part 75 concerning Hg
mass emissions. Each State Plan must also show that the State has the
legal authority to adopt the appropriate emission standards, compliance
schedules, and other requirements.
IV. How Can States Comply With CAMR?
Many States have chosen to meet the CAMR requirements by requiring
new and existing EGUs to participate in the EPA-administered CAMR cap-
and-trade program while many other States have chosen to control
Statewide annual Hg emissions for new and existing EGUs through an
alternative mechanism. Each State that chooses an alternative mechanism
must include with its plan a demonstration that the State Plan will
ensure that the State will meet its assigned State annual EGU Hg
emission budget.
A State submitting a State Plan that requires EGUs to participate
in the EPA-administered CAMR cap-and-trade program may either adopt
regulations that are substantively identical to the EPA model Hg
trading rule (40 CFR part 60, subpart HHHH) or incorporate by reference
the entire model rule. Alternatively, CAMR provides that a State
requiring participation in the cap-and-trade program may adopt
regulations, or an incorporation by reference, that make only limited
changes to the model rule and must otherwise be substantively identical
to the model rule. A State Plan may change the model rule only by
altering the allowance allocation provisions to provide for a State-
specific methodology for allocating Hg allowances. A State's
alternative allowance allocation provisions must meet certain mandatory
allocation timing requirements and must ensure that total allocations
for each calendar year will not exceed the State's annual EGU Hg budget
for that year.
A State may submit a State Plan that establishes an allowance
system that does not meet the above-described requirements for
participation in the EPA-administered CAMR cap-and-trade program and
that does not require such participation, and EPA will review the State
Plan on a case-by-case basis to determine if the plan meets CAMR
requirements applicable to plans not involving such participation.
However, such State Plans must state that Hg allowances issued under
such an allowance system will not qualify as Hg allowances under the
EPA-administered CAMR cap-and-trade program.
V. Analysis of Nevada's CAMR State Plan Submittal
The Nevada State Plan requires EGUs to participate in the EPA-
administered CAMR cap-and-trade program. The State Plan incorporates by
reference some provisions of the EPA model Hg trading rule (40 CFR part
60, subpart HHHH), but replaces other provisions of the model rule. In
particular, the State has chosen to replace model rule provisions
addressing retired units, the standard requirements for sources subject
to the EPA-administered CAMR cap-and-trade program, the allocation of
allowances, and the recordation of allowance allocations. Nevada's rule
also added certain definitions to those in the model rule and adopted
allowance allocation provisions establishing an alternate allowance
allocation methodology.
[[Page 70814]]
Under CAMR, States may establish a different Hg allowance
allocation methodology and still participate in the EPA-administered
CAMR cap-and-trade program if certain mandatory requirements are met
concerning the timing of submission of allocations to EGUs to the
Administrator for recordation and the total amount of allowances
allocated for each control period and if the State Plan is otherwise
substantively identical to the model rule. In adopting alternative Hg
allowance allocation methodologies, States have flexibility with regard
to:
1. The cost to recipients of the allowances, which may be
distributed for free or auctioned;
2. The frequency of allocations (e.g., whether allocations for each
year will be determined in advance by an even longer period than under
the mandatory allowance allocation timing requirements);
3. The basis for allocating allowances, which may be distributed,
for example, based on historical heat input or electric and thermal
output; and
4. The use of allowance set-asides and, if used, their size. See 70
FR 28627.
Nevada's alternative allowance allocation methodology effectively
distributes Hg allowances based upon a unit's actual emissions.
However, while Nevada's State Plan requires sources to participate in
the EPA-administered CAMR cap-and-trade program and so does not state
that Nevada-issued allowances will not qualify as Hg allowances under
the EPA-administered program, Nevada's method for the allocation of
allowances does not comply with the mandatory timing requirements of 40
CFR 60.24(h)(6)(ii)(C) and (D). Under 40 CFR 60.24(h)(6)(ii)(C) and
(D), allowances for existing units must be allocated generally three
years before, and allowances for new units must be allocated by October
31 of, the first control period for which the allowances may be used
for compliance. Nevada's State Plan also differs substantively from
certain other provisions of EPA's model rule that are required for
participation in the EPA-administered CAMR cap-and-trade program.
Specifically, Nevada's State Plan creates restrictions on allowance
transfer and trading, fails to state that an allowance does not
constitute a property right, substitutes the Director of the Nevada
Division of Environmental Protection for the Administrator, lacks
deadlines for recordation of allowance allocations, misstates the
requirements for compliance with the requirement to hold allowances
covering emissions, allows for Director's discretion to create an
exception to the requirement that sources maintain records on-site, and
allows for Director's discretion in specifying the content of CAMR
permit applications and permits. These inconsistencies of Nevada's rule
with the requirements of CAMR are discussed in detail in the Technical
Support Document (TSD) entitled EPA Proposed Analysis of Nevada Clean
Air Mercury Rule State Plan, which is included in the docket for this
notice.
For these reasons, as discussed in detail in the TSD, Nevada's rule
is not approvable under 40 CFR 60.24(h)(6) and (7).\1\
---------------------------------------------------------------------------
\1\ EPA is acting on the final Nevada CAMR State Plan submitted
on November 15, 2006. EPA recognizes that Nevada has since proposed
revisions that would address some, but not all, of the approvability
issues identified above. EPA is not addressing in this notice
Nevada's proposed revisions as they have not yet been adopted or
submitted. However, EPA notes that these proposed revisions do not
address certain approvability issues, including those allocation
timing and restrictions on allowance transfer and trading.
---------------------------------------------------------------------------
VI. Implications of State Plan Disapproval
Under 40 CFR 60.27(b), the Administrator must approve or disapprove
timely submitted State Plans within four months of the deadline for
their submission to the Administrator, i.e., November 17, 2006 in the
case of CAMR State Plans. Moreover, under 40 CFR 60.27(c), the
Administrator must propose a Federal Plan for States that did not
submit State Plans by the submission deadline or whose timely submitted
State Plans the Administrator disapproves. The Administrator must
finalize a Federal Plan for such States under 40 CFR 60.27(d) within
six months of the deadline for their submission to the Administrator,
unless in the meantime the State submits a State Plan that the
Administrator determines to be approvable. EPA's review of Nevada's
State Plan continued beyond the deadline in 40 CFR 60.27(b) because of
the complexity of Nevada's rule and because EPA conducted an extended
dialogue with Nevada in order to understand the State's concerns and to
try to resolve the issues raised by Nevada's State Plan.
In a separate action, EPA has proposed a Federal Plan and intends
to issue a final Federal Plan in the near future. Any final Federal
Plan will generally apply in those States that did not submit a State
Plan by November 17, 2006, whose State Plans submitted by November 17,
2006 have been disapproved by EPA, or whose State Plans submitted after
November 17, 2006 have not been approved. A final determination of the
categories of States to which the Federal Plan will apply will be made
in the notice finalizing a Federal Plan. If EPA finalizes the
disapproval of Nevada's CAMR State Plan and finalizes the Federal Plan
as described above, Nevada EGUs will be subject to the Federal Plan. It
is EPA's intention to work quickly to review any revision of a
disapproved State Plan, so that an approvable State Plan can be
approved and take the place of the Federal Plan.
VII. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget. For this
reason, this action is also not subject to Executive Order 13211,
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action
merely proposes to disapprove State law as not meeting Federal
requirements and would impose no additional requirements. Accordingly,
the Administrator certifies that this proposed rule would not have a
significant economic impact on a substantial number of small entities
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because
this action proposes to disapprove pre-existing requirements under
State law and would not impose any additional enforceable duty beyond
that required by State law, it does not contain any unfunded mandate or
significantly or uniquely affect small governments, as described in the
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).
This proposal also does not have Tribal implications because it
would not have a substantial direct effect on one or more Indian
tribes, 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 by Executive
Order 13175 (65 FR 67249, November 9, 2000).
This proposed action also does not have Federalism implications
because it would 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 (64 FR 43255,
August 10, 1999). This action merely proposes to disapprove a State
rule as failing to implement a Federal standard. It does not alter the
relationship or the distribution of power and responsibilities
established in the
[[Page 70815]]
CAA. This proposed rule also is not subject to Executive Order 13045
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997), because it is not economically
significant. It also does not concern an environmental health or safety
risk the EPA has reason to believe may have a disproportionate effect
on children.
Executive Order 12898, ``Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations,'' requires
Federal agencies to consider the impact of programs, policies, and
activities on minority populations and low-income populations. EPA
guidance \2\ states that EPA is to assess whether minority or low-
income populations face risk or a rate of exposure to hazards that is
significant and that ``appreciably exceed[s] or is likely to
appreciably exceed the risk or rate to the general population or to the
appropriate comparison group.'' (EPA, 1998) Because this rule merely
proposes to disapprove a state rule as failing to implement the Federal
standard established by CAMR, EPA lacks the discretionary authority to
modify today's regulatory decision on the basis of environmental
justice considerations. However, EPA has already considered the impact
of CAMR, including this Federal standard, on minority and low-income
populations. In the context of EPA's CAMR published in the Federal
Register on May 18, 2005, in accordance with E.O. 12898, the Agency has
considered whether CAMR may have disproportionate negative impacts on
minority or low income populations and determined that it does not.

---------------------------------------------------------------------------
In reviewing State Plan submissions, EPA's role is to approve State
choices, provided that they meet the criteria of the CAA generally and
CAMR specifically. In this context, in the absence of a prior existing
requirement for the State to use voluntary consensus standards (VCS),
EPA has no authority to disapprove a State Plan for failure to use VCS.
It would thus be inconsistent with applicable law for EPA, when it
reviews a State Plan submission, to use VCS in place of a State Plan
submission that otherwise satisfies the provisions of the CAA. Thus,
the requirements of section 12(d) of the National Technology Transfer
and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This
proposed rule would not impose an information collection burden under
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501
et seq.).
