Approval and Promulgation of Implementation Plans Florida: 
Prevention of Significant Deterioration

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed approval and proposed conditional approval.

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

SUMMARY: EPA is proposing to conditionally approve State Implementation 
Plan (SIP) revisions submitted by the State of Florida on February 3, 
2006. The proposed revisions modify Florida's Prevention of Significant 
Deterioration (PSD) permitting regulations in the SIP to address 
changes to the federal New Source Review (NSR) regulations, which were 
promulgated by EPA on December 31, 2002, and reconsidered with minor 
changes on November 7, 2003 (collectively, these two final actions are 
referred to as the ``2002 NSR Reform Rules''). The proposed revisions 
include provisions for baseline emissions calculations, an actual-to-
projected-actual methodology for calculating emissions changes, options 
for plantwide applicability limits, and recordkeeping and reporting 
requirements. As part of the conditional approval, Florida will have 
twelve months from the date of EPA's final conditional approval of the 
SIP revisions in which to revise its PSD recordkeeping requirements and 
several definitions in order to be consistent with existing federal 
law.
    In addition to and in conjunction with the proposed conditional 
approval of Florida's PSD permitting program SIP revisions, EPA is 
proposing to approve Florida's concurrent February 3, 2006, request to 
make the State's PSD permitting program applicable to electric power 
plants which are also subject to the Florida Electrical Power Plant 
Siting Act (PPSA). This proposed approval follows the receipt of 
adverse comments on, and EPA's subsequent withdrawal of, EPA's May 25, 
2007, direct final rule granting full approval to Florida to implement 
its PSD permitting program for sources subject to the PPSA.

DATES: Comments must be received on or before May 5, 2008.

I. What actions are being proposed?

    NSR Reform Revisions. On February 3, 2006, the State of Florida, 
through the Florida Department of Environmental Protection (FDEP), 
submitted revisions to the Florida SIP. The submittal consists of 
revisions to the following

[[Page 18467]]

FDEP rules: Chapter 62-204, ``Air Pollution Control--General 
Provisions;'' Chapter 62-210, ``Stationary Sources--General 
Provisions;'' and Chapter 62-212, ``Stationary Sources--Preconstruction 
Review.'' The revisions were made to update the Florida PSD program to 
make it consistent with changes to the federal NSR regulations 
published on December 31, 2002 (67 FR 80186) and November 7, 2003 (68 
FR 63021). EPA is proposing to conditionally approve the February 3, 
2006, SIP submittal consistent with section 110(k)(4) of the Clean Air 
Act (``CAA'' or ``Act'').
    Pursuant to section 110(k)(4) of the CAA, EPA may conditionally 
approve a portion of a SIP revision based on a commitment from the 
state to adopt specific, enforceable measures no later than twelve 
months from the date of final conditional approval. If the state fails 
to commit to undertake the necessary changes, or fails to actually make 
the changes within the twelve month period, EPA will issue a finding of 
disapproval. EPA is not required to propose the finding of disapproval. 
The necessary revisions to the Florida SIP will materially alter the 
existing SIP-approved rule. As a result, the State must also provide a 
new SIP submittal to EPA for approval that includes the rule changes 
within twelve months from the date of EPA's final action conditionally 
approving Florida's PSD program. As with any SIP revision, Florida must 
undergo public notice and comment, and allow for a public hearing (and 
any other procedures required by State law) on the proposed changes to 
its rules. If Florida fails to adopt and submit the specified measures 
by the end of one year (from the final conditional approval), or fails 
to make a SIP submittal to EPA within twelve months following the final 
conditional approval, EPA will issue a finding of disapproval. If 
Florida timely revises its rules and submits the revised SIP submittal, 
EPA will process that SIP revision consistent with the CAA.
    Generally, with regard to the conditional approval of Florida's PSD 
program, Florida must revise its PSD recordkeeping requirements and 
several definitions in the rules. Section III below provides more 
details regarding EPA's analysis of Florida's PSD program and the 
changes that are necessary to the Florida rules in order for full 
approval of Florida's SIP revision.
    Applicability of Florida's SIP-approved PSD permitting program to 
electric power plants. In addition to and in conjunction with the 
proposed conditional approval of Florida's PSD SIP revisions, EPA is 
proposing to approve Florida's concurrent February 3, 2006, request to 
make the State's PSD permitting program applicable to electric power 
plants subject to the Florida PPSA. Any final approval of this request 
would mean that Florida's SIP-approved PSD permitting program, 
including any final conditional approval of the State's PSD revisions 
noted above, would apply to electric power plants in Florida in lieu of 
the current federally delegated PSD program.

II. What is the background of EPA's proposed action on the Florida PSD 
rule revisions?

    On December 31, 2002 (67 FR 80186), EPA published final rule 
changes to 40 Code of Federal Regulations (CFR) parts 51 and 52, 
regarding the CAA's PSD and Nonattainment NSR (NNSR) programs. On 
November 7, 2003 (68 FR 63021), EPA published a notice of final action 
on the reconsideration of the December 31, 2002, final rule changes. In 
that November 7, 2003, final action, EPA added the definition of 
``replacement unit,'' and clarified an issue regarding plantwide 
applicability limitations (PALs). Collectively, these two EPA final 
actions are referred to as the ``2002 NSR Reform Rules.'' The purpose 
of this action is to propose to conditionally approve the SIP submittal 
from Florida, which addresses EPA's 2002 NSR Reform Rules.
    The 2002 NSR Reform Rules are part of EPA's implementation of Parts 
C and D of title I of the CAA, 42 U.S.C. 7470-7515. Part C of title I 
of the CAA, 42 U.S.C. 7470-7492, is the PSD program, which applies in 
areas that meet the National Ambient Air Quality Standards (NAAQS)--
``attainment'' areas--as well as in areas for which there is 
insufficient information to determine whether the area meets the 
NAAQS--``unclassifiable'' areas. Part D of title I of the CAA, 42 
U.S.C. 7501-7515, is the NNSR program, which applies in areas that are 
not in attainment of the NAAQS--``nonattainment'' areas. Collectively, 
the PSD and NNSR programs are referred to as the ``New Source Review'' 
or NSR programs. EPA regulations implementing these programs are 
contained in 40 CFR 51.165, 51.166, 52.21, 52.24, and part 51, appendix 
S.
    The CAA's NSR programs are preconstruction review and permitting 
programs applicable to new and modified stationary sources of air 
pollutants regulated under the CAA. The NSR programs of the CAA include 
a combination of air quality planning and air pollution control 
technology program requirements. Briefly, section 109 of the CAA, 42 
U.S.C. 7409, requires EPA to promulgate primary NAAQS to protect public 
health and secondary NAAQS to protect public welfare. Once EPA sets 
those standards, states must develop, adopt, and submit to EPA for 
approval, a SIP that contains emissions limitations and other control 
measures to attain and maintain the NAAQS. Each SIP is required to 
contain a preconstruction review program for the construction and 
modification of any stationary source of air pollution to assure that 
the NAAQS are achieved and maintained; to protect areas of clean air; 
to protect air quality related values (such as visibility) in national 
parks and other areas; to assure that appropriate emissions controls 
are applied; to maximize opportunities for economic development 
consistent with the preservation of clean air resources; and to ensure 
that any decision to increase air pollution is made only after full 
public consideration of the consequences of the decision.
    The 2002 NSR Reform Rules made changes to five areas of the NSR 
programs. In summary, the 2002 Rules: (1) Provide a new method for 
determining baseline actual emissions; (2) adopt an actual-to-
projected-actual methodology for determining whether a major 
modification has occurred; (3) allow major stationary sources to comply 
with plant-wide applicability limits to avoid having a significant 
emissions increase that triggers the requirements of the major NSR 
program; (4) provide a new applicability provision for emissions units 
that are designated clean units; and (5) exclude pollution control 
projects (PCPs) from the definition of ``physical change or change in 
the method of operation.'' On November 7, 2003, EPA published a notice 
of final action on its reconsideration of the 2002 NSR Reform Rules (68 
FR 63021), which added a definition for ``replacement unit'' and 
clarified an issue regarding PALs. For additional information on the 
2002 NSR Reform Rules, see 67 FR 80186 (December 31, 2002), and http://
www.epa.gov/nsr.
    After the 2002 NSR Reform Rules were finalized and effective (March 
3, 2003), industry, state, and environmental petitioners challenged 
numerous aspects of the 2002 NSR Reform Rules, along with portions of 
EPA's 1980 NSR Rules (45 FR 52676, August 7, 1980). On June 24, 2005, 
the United States Court of Appeals for the District of Columbia Circuit 
(DC Circuit Court) issued a decision on the challenges to the 2002 NSR 
Reform Rules. New York v. United States, 413 F.3d 3 (DC Cir. 2005). In 
summary, the DC Circuit Court vacated portions of the

[[Page 18468]]

rules pertaining to clean units and PCPs, remanded a portion of the 
rules regarding recordkeeping, 40 CFR 52.21(r)(6) and 40 CFR 
51.166(r)(6), and either upheld or did not comment on the other 
provisions included as part of the 2002 NSR Reform Rules. On June 13, 
2007 (72 FR 32526), EPA took direct final action to revise the 2002 NSR 
Reform Rules to remove from federal law all provisions pertaining to 
clean units and the PCP exemption that were vacated by the DC Circuit 
Court. This proposed action on the Florida SIP is consistent with the 
decision of the DC Circuit Court because Florida's submittal does not 
include any portions of the 2002 NSR Reform Rules that were vacated as 
part of the June 2005 decision.
    With regard to the remanded portions of the 2002 NSR Reform Rules 
related to recordkeeping, on December 21, 2007, EPA took final action 
on the proposed revisions by establishing that ``reasonable 
possibility'' applies where source emissions equal or exceed 50 percent 
of the CAA NSR significance levels for any pollutant (72 FR 72607). The 
``reasonable possibility'' provision identifies for sources and 
reviewing authorities the circumstances under which a major stationary 
source undergoing a modification that does not trigger major NSR must 
keep records. Florida's regulations do not include the ``reasonable 
possibility'' language. Florida's SIP revisions require all 
modifications that use the actual-to-projected-actual methodology to 
meet the recordkeeping requirements. Thus, with regard to the 
reasonable possibility issue, Florida's rules are at least as stringent 
as the current federal rules (see, e.g., F.A.C. section 62-212.300). 
However, another aspect of Florida's recordkeeping requirements is not 
consistent with the recordkeeping provisions set forth in the federal 
rules at 40 CFR 51.166(r)(6). As is explained in more detail below, 
Florida will have to revise its recordkeeping requirements as part of 
the proposed conditional approval.
    The 2002 NSR Reform Rules require that state agencies adopt and 
submit revisions to their SIP permitting programs implementing the 
minimum program elements of the 2002 NSR Reform Rules no later than 
January 2, 2006. (Consistent with changes to 40 CFR 51.166(a)(6)(i), 
state agencies are now required to adopt and submit SIP revisions 
within 3 years after new amendments are published in the Federal 
Register.) State agencies may meet the requirements of 40 CFR part 51, 
and the 2002 NSR Reform Rules, with different but equivalent 
regulations.
    On February 3, 2006, FDEP submitted a SIP revision for the purpose 
of revising the State's PSD permitting provisions. These changes were 
made primarily to adopt EPA's 2002 NSR Reform Rules. These revisions 
became State-effective on February 2, 2006, and February 12, 2006. Even 
though Florida currently has nonattainment rules approved in the SIP, 
this submittal did not include revisions to the NNSR rules because 
there are currently no nonattainment areas in Florida. Copies of 
Florida's revised PSD rules, as well as the State's Technical Support 
Document (TSD), can be obtained from the Docket, as discussed in the 
ADDRESSES section above.
    As is discussed in further detail below, EPA believes the revisions 
contained in the Florida submittal are approvable for inclusion into 
the Florida SIP so long as the specific changes described below are 
made within twelve months of the date of EPA's final conditional 
approval. As a result, EPA is proposing to conditionally approve the 
Florida SIP revisions, consistent with section 110(k)(4) of the CAA.

III. What is EPA's Analysis of Florida's PSD program revisions and what 
are the conditions for full SIP-approval?

    This section summarizes EPA's analysis of the changes being 
proposed for inclusion into the Florida SIP.
    F.A.C. Chapter 62-204, entitled ``Air Pollution Control--General 
Provisions'' contains general air pollution control requirements that 
apply regardless of the type or size of the emissions source. F.A.C. 
section 62-204.260 sets forth PSD increments for pollutants for which 
EPA has established such increments. Definitions at section 62-204.200 
describe those emissions which affect (i.e. expand or consume) PSD 
increment. Under previous FDEP rules, some provisions related to 
increment consumption and expansion were located at section 62-212.400. 
The current rule revisions consolidate all such provisions in the 
definitions at section 62-204.200 for greater clarity. In addition, 
rule language has been amended to more closely reflect the federal 
rules.
    F.A.C. Chapter 62-210, entitled ``Stationary Sources--General 
Requirements,'' contains definitions of terms used in Chapter 62-212, 
as well as other stationary source rules. Chapter 62-210 also 
establishes general permitting, public notice, reporting, and permit 
application requirements. Chapter 62-212, entitled ``Stationary 
Sources--Preconstruction Review'' contains specific preconstruction 
permitting requirements for various types of air construction permits, 
including minor source permits, PSD permits, NNSR permits, and the more 
recently added PAL permits. Revisions were made to these rules to 
incorporate changes resulting from the 2002 NSR Reform Rules, with the 
exception that F.A.C. section 62-212.500, entitled, ``Preconstruction 
Review for Nonattainment Areas'' was not revised since there are no 
longer any nonattainment areas in Florida. This rule will need to be 
amended if nonattainment areas are designated in Florida in the future.
    F.A.C. section 62-212.400 contains the State's PSD preconstruction 
review program as required under Part C of title I of the CAA. The PSD 
program applies to major stationary sources or modifications 
constructing in areas that are designated as attainment or 
unclassifiable with respect to the NAAQS. Florida's PSD program was 
originally approved into the SIP by EPA on December 22, 1983, and has 
been revised several times. The current changes to F.A.C. Chapters 62-
204, 62-210 and 62-212, which EPA is now proposing to conditionally 
approve into the Florida SIP, were submitted to update the existing 
Florida regulations to be consistent with the current federal PSD 
rules, including the 2002 NSR Reform Rules. The SIP revision addresses 
baseline actual emissions, actual-to-projected-actual applicability 
tests, and PALs.
    EPA's evaluation of the Florida SIP submittal included a line-by-
line comparison of the proposed revisions with the federal 
requirements. As a general matter, state agencies may meet the 
requirements of 40 CFR part 51, and the 2002 NSR Reform Rules, with 
different but equivalent regulations. While some states choose to 
incorporate by reference the applicable federal rules, other states 
(such as Florida) choose to draft rules that track the federal language 
but contain differences. As part of its February 3, 2006, SIP 
submittal, Florida provided EPA with an Equivalency Determination and 
Response to Comments (ED and RTC) that address differences from the 
federal rules noted by EPA in its comments on Florida's prehearing 
submittal. As a point of clarification, although FAC section 62-
204.800, ``Federal Regulations Adopted by Reference,'' includes 40 CFR 
part 52, this Florida rule does not legally ``incorporate by 
reference'' the entirety of part 52. According to Florida's ED and RTC, 
the reference to part 52 does not make those

[[Page 18469]]

regulations applicable, but rather, other rules, such as the PSD rule 
currently at issue, define how the elements of part 52 will apply in 
Florida.
    Although EPA has determined that some of the differences in 
Florida's PSD program are acceptable, some differences are not 
consistent with the federal rules. Therefore, EPA has determined that 
Florida's PSD program does not meet all the program requirements for 
the preparation, adoption and submittal of implementation plans for the 
Prevention of Significant Deterioration of Air Quality, set forth at 40 
CFR 51.166 and revisions are necessary for full approval.
    The required changes relate to the definitions of ``new emissions 
unit,'' ``PSD pollutant,'' ``significant emissions rate,'' and the 
recordkeeping requirements found at 51.166(r)(6). Consistent with 
section 110(k)(4) of the CAA, EPA may conditionally approve Florida's 
SIP revision based on the State's commitment to adopt specific, 
enforceable measures by a date certain, not to exceed one year after 
the date of the final conditional approval.
    A discussion of the specific changes to Florida's rules comprising 
the SIP revision, as well as the additional changes that must be made 
by Florida as part of the conditional approval, follows. The discussion 
addresses both acceptable deviations from the federal rules, as well as 
the differences that are subject to the conditional approval.

1. New Emissions Unit

    Florida's definition for ``new emissions unit'' for PSD purposes is 
found in F.A.C. section 62-210.200(184). \1\ This definition is not 
consistent with the federal definition found at 40 CFR 51.166(b)(7)(i). 
Pursuant to federal law, a ``new emissions unit'' is ``any emissions 
unit that is (or will be) newly constructed and that has existed for 
less than 2 years from the date such emissions unit first operated.'' 
40 CFR 51.166(b)(7)(i). Under Florida law, however, a ``new emissions 
unit'' is ``any emissions unit that is or will be newly constructed and 
that has enlisted for less than 2 years from the date of beginning 
normal operation.'' See, F.A.C. section 62-210.200(184) (emphasis 
added). Florida's ED and RTC indicate that the use of the term 
``beginning normal operation'' takes into account that most new units 
undergo a ``shakedown'' period during which the unit is operating but 
may not have normal, representative emissions. FDEP therefore believes 
that this term clarifies the intent of the federal requirement. EPA 
disagrees that this language is equivalent to the federal rule. Florida 
must revise its regulations to better define what is meant by 
``beginning normal operation,'' to ensure that the ``shakedown'' period 
does not continue for an unbounded period of time. EPA recommends that 
Florida adopt the language of the federal rule. However, if Florida 
chooses otherwise, FDEP will need to provide EPA with an equivalency 
demonstration supporting the new, more specific, regulation. In 
addition, EPA also identified a typographical error in this provision 
that should be addressed. The language ``* * * that has enlisted for 
less than * * *'' should read ``* * * that has existed for less than * 
* *.'' F.A.C. section 62-210.200(184) (emphasis added).
---------------------------------------------------------------------------

    \1\ The references to the Florida regulations in this notice 
correspond to the numbering in the SIP submittal. Since Chapter 62-
210 contains definitions for other stationary source rules and these 
definitions are maintained in alphabetical order, the references 
given in this notice do not correspond to the current Florida 
regulations due to subsequent amendments to Florida stationary 
rules. This is the case for all definitions being discussed in this 
notice.
---------------------------------------------------------------------------

2. Pollution Control Project (PCP)

    As mentioned previously, the PCP exemption provisions of the 
federal rules, including the definition of ``pollution control 
project,'' were vacated by the DC Circuit Court. Florida's regulations 
still include a definition for ``pollution control project'' (found at 
F.A.C. section 62-210.200(209)). In its ED and RTC, Florida explains 
that this term is no longer used anywhere within the Florida 
regulations and the intent is to exclude clean coal technology 
demonstration projects from triggering a major modification. However, 
such projects are excluded at 51.166(b)(2)(iii)(j), and F.A.C. section 
62-210.200(161)(c)9. Even though Florida's definition of ``pollution 
control project'' is not the same as the vacated federal definition, 
EPA believes that the use of the term ``PCP'' in the Florida 
regulations may be confusing to both the public and the regulated 
community, and could be misconstrued as the vacated portion of the 
federal rules. Because the clean coal technology demonstration project 
exemption is already independently defined and included in F.A.C. 
section 62-210.200(190)(c)9, EPA recommends that the term ``pollution 
control project'' be removed from the rules to be included in the 
Florida SIP.

3. Regulated NSR Pollutant

    Florida's definition of ``PSD Pollutant'' found at F.A.C. section 
62-210.200(219) is intended to be equivalent to the federal definition 
of ``Regulated NSR pollutant'' at 51.166(b)(49). Florida defines ``PSD 
Pollutant'' as ``any pollutant listed as having a significant emissions 
rate as defined in F.A.C. section 62-210.200.'' The definition of 
``significant emissions rate,'' found at F.A.C. section 62-
210.200(243), includes ``a rate listed at 40 CFR 52.21(b)(23)(i) * * * 
specifically the following rates,'' and proceeds to list rates for 
carbon monoxide, nitrogen oxides, sulfur dioxide, particulate matter, 
ozone, lead, fluorides, sulfuric acid mist, hydrogen sulfide, total 
reduced sulfur, reduced sulfur compounds, municipal waste combustor 
organics, metals, and acid gases, municipal solid waste landfills 
emissions, and mercury. The federal definition of ``Regulated NSR 
Pollutant'' includes: (1) Any pollutant for which a NAAQS has been 
promulgated and any constituents or precursors for such pollutants 
identified by the Administrator; (2) any pollutant that is subject to 
any standard promulgated under section 111 of the Act; (3) any Class I 
or II substance subject to a standard promulgated under or established 
by title VI of the Act; and (4) any pollutant that otherwise is subject 
to regulation under the Act.
    In its ED and RTC, Florida explains that its definition of 
significant emissions rate includes all pollutants for which a NAAQS 
has been promulgated thus far, all precursors for such pollutants which 
have thus far been identified by the Administrator, all pollutants 
subject to standards promulgated under section 111 of the Act, and all 
pollutants thus far regulated under the Act. Florida acknowledges that 
its rules do not include ozone depleting substances (i.e., Class I and 
Class II substances subject to a standard under title VI of the CAA) in 
the definition of PSD pollutant. Because ozone depleting substances are 
regulated NSR pollutants pursuant to federal law, Florida must also 
regulate such pollutants in order for its PSD program to meet the 
requirements of the federal program. Therefore, as part of the 
conditional approval, Florida must revise its rules to include Class I 
and Class II substances in its list of PSD pollutants.

4. Significant Emissions Rate

    The definition of ``significant emissions rate,'' found at F.A.C. 
section 62-210.200(243), includes ``a rate listed at 40 CFR 
52.21(b)(23)(i) * * * specifically the following rates,'' and proceeds 
to list rates for specific pollutants. Federal regulations define 
``significant'' as a rate of emissions that

[[Page 18470]]

would equal or exceed a pollutant specific list of emissions rates. 
See, 40 CFR Part 51.166(b)(23)(i). In addition, federal law defines 
significant as ``any emissions rate'' of a regulated NSR pollutant that 
is not listed in Sec.  51.166(b)(23)(i), and ``any emissions rate'' at 
a major stationary source constructing within 10 kilometers of a Class 
I area, which would have an impact on such area equal to or greater 
than 1 microgram per cubic meter ([mu]g/m\3\) over a 24-hour average. 
Florida's PSD rules do not include ``any emissions rate'' for a 
pollutant that is not listed in the significant emissions rate list, 
but that could otherwise be considered a regulated NSR pollutant (i.e. 
``any pollutant that is otherwise subject to regulation under the 
Act''). In addition, Florida's PSD rules limit the Class I area impact 
provision to only those pollutants that are listed in the significant 
emissions rates list. See, F.A.C. section 62-210.200(243)(b). In its ED 
and RTC, Florida explains that its PSD rules include all pollutants 
that are currently regulated under the federal rules, and which fall 
within FDEP's existing statutory authority. For those pollutants which 
may become regulated NSR pollutants in the future, FDEP commits to 
adopting those pollutants into the State's PSD rules as soon as 
possible after EPA's promulgation. EPA agrees that Florida's PSD rules 
include significant emissions rates for all currently regulated NSR 
pollutants, except ozone depleting substances (discussed above), and 
that Florida's approach to adopting any other pollutants as part of its 
definition of PSD pollutant in an expeditious manner after promulgation 
by EPA, is an acceptable approach to ensuring that Florida's PSD 
program is consistent with the federal PSD program.

5. Mercury

    As a general matter, hazardous air pollutants (HAPs) are not 
regulated NSR pollutants unless they are also regulated as a 
constituent or precursor of a general pollutant listed under Section 
108 of the Act. Pursuant to Section 112(b)(6) of the CAA, the PSD 
provisions of the CAA ``shall not apply to pollutants listed in'' 
Section 112. Mercury is specifically listed as a HAP in Section 
112(b)(1). As a result, the CAA's PSD program does not apply to 
mercury. Section 110 of the CAA, governing SIP review and approval, 
describes what types of regulations should be included in the SIP; 
specifically, regulations supporting attainment and maintenance of the 
NAAQS. Mercury is not identified as a criteria pollutant for which a 
NAAQS is established, nor is it identified as a constituent of such a 
pollutant or a precursor of such a pollutant. As a result, regulations 
governing mercury should not be included in SIPs. As previously 
mentioned, Florida's definition of ``significant emissions rate,'' 
found at F.A.C. section 62-210.200(243), includes ``a rate listed at 40 
CFR 52.21(b)(23)(i) * * * specifically the following rates,'' and it 
proceeds to list rates for among other pollutants, mercury.
    In its ED and RTC, Florida explains that its PSD program has 
included a significant emission rate for mercury since the 1980s. 
However, following the enactment of the 1990 amendments to the CAA, EPA 
advised states to remove HAPs from PSD rules included in the SIP. 
Florida did remove some HAPs, but retained mercury. Because the 1990 
CAA Amendments (and the addition of Section 112(b)(6)) has altered 
EPA's approach with regard to mercury, EPA is now seeking to remedy the 
inclusion of mercury in the Florida SIP as a PSD pollutant. Notably, 
Florida may retain mercury as a regulated pollutant pursuant to State 
authority and State law. However, mercury cannot be included as a 
regulated pollutant in the SIP. As part of the conditional approval, 
Florida must withdraw its request that EPA include a significant 
emissions rate for mercury in the Florida SIP, specifically section 
200.243(a)2 of F.A.C. Chapter 62-210.

6. Recordkeeping Requirements

    Federal rules at 40 CFR 51.166(r)(6)(i)(c) require that the owner 
or operator document and maintain a record of the description of the 
applicability test used to determine that the project is not a major 
modification for any regulated NSR pollutant, including the baseline 
actual emissions, the projected actual emissions, the amount of 
emissions excluded under the definition of ``projected actual 
emissions'' (i.e. that portion of the unit's emissions following the 
project that an existing unit could have accommodated during the 
consecutive 24-month period used to establish the baseline actual 
emissions and that are also unrelated to the particular project, 
including any increased utilization due to product demand growth) and 
an explanation as to why this amount was excluded, and any netting 
calculations if applicable. F.A.C. section 62-212.300(3)(a) requires 
each applicant to provide at a minimum, the nature and amounts of 
emissions from the emissions unit, including baseline actual emissions 
and projected actual emissions when used to determine PSD 
applicability, and when used to establish a PAL. However, Florida rules 
do not specifically require a record of the amount of emissions 
excluded pursuant to the projected actual emissions requirements, an 
explanation as to why these emissions were excluded, and any netting 
calculations if applicable. As part of the conditional approval, 
Florida must revise its rules to make the recordkeeping requirements 
consistent with the federal recordkeeping requirements at 40 CFR 
51.166(r)(6).

7. Replacement Unit

    As previously mentioned, on November 7, 2003 (68 FR 63021), EPA 
added a definition of ``replacement unit'' to federal NSR rules. See, 
40 CFR 51.166(32). EPA also revised the definition of ``emissions 
unit'' to clarify that a replacement unit is considered an existing 
emissions unit and therefore is eligible for the actual-to-projected-
actual test for major NSR applicability determinations. Florida rules 
do not include a definition of replacement unit, and do not specify in 
the definition of existing emissions unit that a replacement unit is 
considered an existing emissions unit. As stated in the preamble to the 
November 7, 2003 (68 FR 63021) rule amendments, the December 2002 
rules, ``* * * as supplemented by the discussion in the December 2002 
preamble, are self-implementing for replacement units.'' Florida 
intends to implement these provisions consistent with federal 
regulations. In other words, in Florida a replacement unit is 
considered an existing emissions unit and therefore is eligible for the 
actual-to-projected-actual test for major NSR applicability test 
determinations. Therefore, based on Florida's intent to implement these 
provisions consistent with federal regulations, EPA does not believe 
that this difference from the federal regulations makes Florida's PSD 
program less stringent than the federal program.

8. Malfunction Emissions

    Federal regulations require the inclusion of emissions associated 
with malfunctions in the calculation of ``projected actual emissions'' 
and ``baseline actual emissions.'' Florida's definitions of ``projected 
actual emissions'' and ``baseline actual emissions'' at F.A.C. sections 
62-210.200(34) and (215) respectively, do not require the inclusion of 
emissions associated with malfunctions. Florida will be relying only on 
quantifiable emissions that can be verified. Given that Florida will be 
consistently applying this approach for both ``projected actual 
emissions'' and

[[Page 18471]]

``baseline actual emissions'' and that this approach will not prevent 
malfunctions from being exceedances of applicable standards, EPA has 
determined that this difference does not make Florida's PSD program 
less stringent than the federal program. These changes do not affect 
source obligations regarding excess emissions related notifications 
that may be required by State or federal law.

9. Major Stationary Source

    One of the changes proposed in the Florida submittal is to replace 
the State definition of ``major stationary source'' with the federal 
definition contained at 40 CFR 52.21(b). For the most part, the effect 
of this change is simply to reword the State definition so that it 
reads the same as the federal definition. EPA notes, however, that in 
replacing the Florida definition with the federal definition, the State 
has adopted the phrase ``except the activities of any vessel.'' This 
phrase was remanded and vacated by the DC Circuit Court, and Florida 
had explicitly excluded this language from the State rule when it 
initially adopted the State PSD regulations. See, Natural Resources 
Defense Council v. EPA, 725 F.2d 761 (DC Cir. 1984). This change may 
have the effect of excluding activities that were previously covered by 
the state rule. Hence, EPA requests clarification as to whether it is 
the state's intention to amend the SIP to include this language, or 
whether it was an unintended consequence of adopting the federal 
definition verbatim.
    In summary, EPA is proposing to conditionally approve, into 
Florida's SIP, revisions to Florida's PSD permitting program. As part 
of the conditional approval mechanism, within twelve months of EPA's 
final action on the conditional approval, the State must: (1) Revise 
the definition of ``new emissions unit'' to be consistent with the 
federal definition or revise the definition to define what is meant by 
``beginning normal operation'' and provide an equivalency demonstration 
supporting the revised definition; (2) revise the definition of 
``significant emissions rate'' to include ozone depleting substances; 
(3) withdraw the request that EPA include a significant emissions rate 
for mercury in the Florida SIP, specifically section 200.243(a)2 of 
F.A.C. Chapter 62-210; and (4) revise the recordkeeping requirements at 
F.A.C. section 62-212.300 to be consistent with federal requirements. 
If Florida fails to comply with these four requirements in the 
specified period of time, EPA will issue a finding of disapproval.

IV. What is the background of prior EPA action on Florida's PSD program 
for electric power plants?

    For reasons described further below, electric power plants subject 
to the Florida PPSA have historically been permitted by FDEP (through a 
federal delegation of authority from EPA) under the federal PSD program 
rather than the Florida SIP-approved PSD permitting program. With the 
reasons for the necessity of such delegation of federal authority 
removed, Florida requests that electric power plants within the State 
now be permitted under the State's SIP-approved PSD permitting program. 
Because EPA agrees with Florida that the necessity for such federal 
delegation no longer exists, EPA is proposing to approve Florida's 
request to make the State's PSD permitting program (rather than the 
federal PSD permitting program) applicable to electric power plants in 
the State.
    As noted earlier, Part C of the CAA establishes the PSD permitting 
program--a preconstruction review program that applies to areas of the 
country that have attained the NAAQS. CAA 160-169, 42 U.S.C. 7470-7479. 
In such areas, a major stationary source may not begin construction or 
undertake certain modifications without first obtaining a PSD permit. 
In broad overview, the program (1) limits the impact of new or modified 
major stationary sources on ambient air quality and (2) requires the 
application of state-of-the-art pollution control technology, known as 
best available control technology. CAA 165, 42 U.S.C. 7475.
    EPA has promulgated two largely identical sets of regulations to 
implement the PSD program. One set, at 40 CFR 52.21, contains EPA's own 
federal PSD program under which EPA is the permitting authority in 
states operating without an EPA-approved state program. The other set 
of regulations contains minimum requirements that state PSD programs 
must meet to be approved by EPA as part of a SIP. 40 CFR 51.166. Over 
time, most states have received EPA approval for their PSD programs.
    In order to comply with the established minimum requirements of the 
CAA, Florida adopted its own PSD regulations on June 10 and October 28, 
1981. The Florida PSD program was proposed for approval on December 14, 
1982 (47 FR 55964) and initially approved by EPA into the Florida SIP 
on December 22, 1983 (48 FR 52713). The approval transferred to FDEP 
the legal authority to process and issue PSD permits to sources in 
Florida that are required to obtain PSD permits.
    One category of sources not covered by EPA's 1983 approval of 
Florida's PSD program was electric power plants. This was because, at 
the time, a separate Florida law known as the Florida Electrical Power 
Plant Siting Act (PPSA), Florida Statutes Section 403.501 et seq., 
required permits for electric power plants to be issued solely by the 
Power Plant Site Certification Board under the PPSA, rather than by 
FDEP under Florida's PSD regulations. Such a conflict between the PPSA 
and Florida's PSD program created impediments to implementation and 
enforcement of the State's PSD program by FDEP for such power plants 
and precluded EPA's SIP-approval of Florida's PSD program as to these 
sources. As a result, on November 5, 1985, EPA delegated partial 
authority to FDEP to conduct the technical and administrative portion 
of the federal PSD program for power plants subject to the Florida PPSA 
(with EPA retaining final permitting authority). Letter from Jack E. 
Ravan, EPA Region 4, to Victoria J. Tschinkel, Florida Department of 
Environmental Regulation (November 5, 1985).
    On July 1, 1986, the Florida Legislature amended the PPSA in an 
effort to extricate the implementation of PSD regulations from the 
State's non-SIP power plant siting regulations and thereby allow FDEP 
to issue PSD permits to those sources subject to the PPSA. On its face, 
the 1986 Florida legislative amendment appeared to provide FDEP with 
authority to fully implement (i.e., issue and enforce) federal PSD 
regulations for sources subject to the PPSA. Thus, on September 25, 
1986, EPA restored full delegation of federal authority to Florida for 
these sources. Public notice of this restoration of full federal 
delegation was published on October 27, 1986 (51 FR 37972).
    Although full federal delegation was restored to FDEP in October 
1986, Florida did not subsequently submit to EPA a SIP revision 
requesting approval to apply its SIP-approved State PSD program to 
electrical power plants subject to the PPSA (in lieu of the fully 
delegated federal PSD program). Thus, FDEP continued to issue permits 
to sources subject to the PPSA under its federally-delegated authority 
until 1992. However, in February 1992, EPA became aware of an issued 
Florida court opinion wherein the state court expressly declared that 
Florida's 1986 legislative amendments to the PPSA did not confer on 
FDEP the authority to issue federally-enforceable PSD permits

[[Page 18472]]

containing conditions which differed from those imposed by the PPSA 
Siting Board during the source's site certification. Letter from Greer 
C. Tidwell, EPA Region 4, to Carol M. Browner, Florida Department of 
Environmental Regulation (February 5, 1992); TECO Power Services Corp. 
v. Florida Department of Environmental Regulation, First District Court 
of Appeal, Case No, 91-300 (December 20, 1991). In response to EPA's 
inquiries concerning this state court opinion, FDEP responded that 
``the practical effect of the decision is to render ineffective the 
1986 amendments and return the law to the same essential configuration 
as it appeared in 1985. Therefore, in the absence of further amendment 
to the PPSA, it would appear necessary for EPA to resume final 
permitting authority over PSD for new PPSA sources.'' Letter from Carol 
M. Browner, Florida Department of Environmental Regulation, to Greer C. 
Tidwell, EPA Region 4 (April 27, 1992). EPA agreed with FDEP, and 
consequently, on August 7, 1992, we revoked Florida's full federal 
delegation of PSD authority for PPSA sources. FDEP, however, retained 
partial federal delegation to conduct the technical and administrative 
portion of the federal PSD program for power plants subject to the 
Florida PPSA (with EPA again retaining final permitting authority). 
Letter from Greer C. Tidwell, EPA Region 4, to Carol M. Browner, 
Florida Department of Environmental Regulation (August 7, 1992).
    In 1993, the Florida Legislature again amended the PPSA to address 
concerns over the inappropriate influence of the Florida Power Plant 
Siting Board's certification decisions on the PSD permitting process. 
The amendments, which took effect on April 22, 1993, expressly provided 
that the ``Department's action on a federally required new source 
review or prevention of significant deterioration permit shall differ 
from the actions taken by the siting board regarding the certification 
if the federally approved state implementation plan requires such a 
different action to be taken by the department. Nothing in this part 
the PPSA shall be construed to displace the federally approved permit 
program.'' In light of this 1993 amendment to the PPSA, FDEP requested 
that EPA grant it full federal delegation of PSD permitting authority 
for sources subject to both the federal PSD regulations and the PPSA. 
Letter from Virginia B. Wetherell, Florida Department of Environmental 
Protection, to Patrick Tobin, EPA Region 4 (September 27, 1993) . 
Because the 1993 PPSA amendment made clear that FDEP is the final 
permitting authority for PSD and new source review permits and can act 
in a manner different from the PPSA Siting Board if Florida's PSD or 
new source review regulations require such a different action, EPA once 
again granted full federal delegation to FDEP on October 26, 1993. 
Letter from Patrick Tobin, EPA Region 4, to Virginia Wetherell, Florida 
Department of Environmental Protection. (October 26, 1993).
    The statutory amendment to the PPSA made by the Florida Legislature 
in 1993 forms the basis of the State's 2006 request for EPA approval to 
make Florida's SIP-approved State PSD program, rather than the federal 
PSD program, applicable to sources subject to the PPSA. In addition, 
during EPA's review of this request, the PPSA was again amended (on 
June 19, 2006), to among other things, further extricate Florida's PSD 
permitting process from its PPSA process. See, Florida Public Health 
Code 403.0872. Specifically, language requiring that a PPSA application 
for certification include ``documents necessary for the department to 
render a decision on any permit required pursuant to any federally 
delegated or approved permit program'' was deleted from the PPSA; 
language requiring that FDEP's action on a PSD permit be based on the 
recommended order of the PPSA certification hearing was removed; and 
requirements that administrative procedures used in the issuance of PSD 
and operating permits follow the administrative procedures of the PPSA 
were also removed.
    Following our review of both the 1993 and June 19, 2006, amendments 
to the PPSA, the Agency published a direct final rule on May 25, 2007, 
finding that the PPSA amendments provided FDEP the authority to fully 
implement and enforce Florida's PSD program for electric power plants 
located within the State and we granted it full approval to implement 
the State's PSD program for electric power plants subject to the PPSA. 
72 FR 29287 (May 25, 2007). However, because adverse comments on the 
direct final rule were received, we withdrew the rule on June 28, 2007 
(72 FR 35355) and indicated that the rule would not take effect.

V. What is the basis for EPA's proposed SIP-approval of the inclusion 
of electric power plants in Florida's PSD program?

    EPA continues to believe, for the reasons detailed above, that the 
1993 and June 2006 Florida legislative amendments to the State's PPSA 
rectified past concerns that the Florida PPSA infringed on FDEP's 
authority to issue State PSD permits to sources subject to both the 
State's PSD regulations and the Florida PPSA in such a manner that SIP-
approval of the State's PSD program for those sources was precluded. We 
also believe that by proposing this SIP-approval through this 
rulemaking (rather than by direct final rulemaking) and in conjunction 
with our proposed action on the Florida PSD program SIP revisions, we 
have addressed the main concerns raised by commenters in response to 
our May 25, 2007, direct final rule. For example, a number of 
environmental organizations, in jointly submitted comments, expressed 
concern that a direct final rulemaking was not the proper process for 
this particular SIP action because of public interest in providing 
comments, that any SIP-approval to make the State's PSD program, rather 
than the federal PSD program, applicable to electric power plants in 
Florida required a full review of the State's PSD regulations to ensure 
compliance with federal law, and that any such SIP-approval should be 
done in conjunction with a review of the State's PSD regulatory 
revisions made for purposes of addressing EPA's 2002 NSR Reform Rules.
    While EPA disagrees that our previous direct final rulemaking for 
this matter was not procedurally appropriate and that a wholesale 
revisiting of all Florida PSD regulations is required in order to make 
the State's PSD program applicable to sources covered by the PPSA, we 
believe that there is value-added to the public's review of this matter 
by including it with our proposed action on the State's current PSD 
revisions. In addition, we have, in response to other comments made on 
our May 2007 direct final rule, added more detail and Docket material 
in this proposed rulemaking action in support of the various 
delegations of federal authority made to FDEP since 1985 in response to 
the PPSA problem. Finally, with regard to several remaining comments on 
the May 2007 direct final rule, EPA notes that SIP approval actions, 
whether done through a direct final rulemaking process or a proposed/
final rulemaking process are not Section 307(d) rulemakings under the 
CAA and do not require the inclusion of elements listed in Section 
307(d)(3). Rather, EPA chooses to use the Administrative Procedure 
Act's notice and comment rulemaking process to ensure public notice of 
EPA action. In any event, we believe that today's proposed rulemaking 
includes all information

[[Page 18473]]

necessary for informed public comment on the proposed approval.

VI. Proposed Action

    EPA is proposing to conditionally approve revisions to the Florida 
SIP (F.A.C. Chapters 62-204, 62-210 and 62-212) submitted by FDEP on 
February 3, 2006. As part of the conditional approval, Florida must (1) 
revise the definition of ``new emissions unit'' to be consistent with 
the federal definition or revise the definition to define what is meant 
by ``beginning normal operation'' and provide an equivalency 
demonstration supporting the revised definition; (2) revise the 
definition of ``significant emissions rate'' to include ozone depleting 
substances; (3) withdraw the request that EPA include a significant 
emissions rate for mercury in the Florida SIP, specifically section 
200.243(a) 2 of F.A.C. Chapter 62-210; and (4) revise the recordkeeping 
requirements at 62-212.300 to be consistent with federal requirements.
    In addition to and in conjunction with the proposed conditional 
approval of Florida's PSD SIP revisions, EPA is proposing to approve 
Florida's concurrent February 3, 2006, request to make the State's PSD 
permitting program applicable to electric power plants subject to the 
Florida PPSA. Any final approval of this request would mean that 
Florida's SIP-approved PSD permitting program, including any final 
conditional approval of the State's PSD revisions noted above, would 
apply to electric power plants in Florida in lieu of the current 
federally delegated PSD program.

VII. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), these 
proposed actions are not ``significant regulatory actions'' and 
therefore are not subject to review by the Office of Management and 
Budget. For this reason, these actions are also not subject to 
Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 
28355, May 22, 2001). These proposed actions merely propose to approve 
State law as meeting Federal requirements and impose no additional 
requirements beyond those imposed by State law. Accordingly, the 
Administrator certifies that the proposed approvals in this proposed 
rule will 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 rule proposes to approve pre-existing 
requirements under State law and does 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 proposed rule also does not have tribal implications because 
it will 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 (59 FR 22951, November 9, 2000). These proposed actions 
also do not have Federalism implications because they do 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). 
These proposed actions merely propose to approve State rules 
implementing a Federal standard, and do not alter the relationship or 
the distribution of power and responsibilities established in the 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 approves State rules 
implementing a Federal standard.
    In reviewing SIP submissions, EPA's role is to approve State 
choices, provided that they meet the criteria of the CAA. 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 SIP submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a SIP 
submission, to use VCS in place of a SIP 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 does not impose 
an information collection burden under the provisions of the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
