Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Revisions to Particulate Matter Rules

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: On March 14, 2008, EPA proposed to approve Indiana's February 
21, 2008, request to revise its particulate matter State Implementation 
Plan (SIP) for sources in Clark, Dearborn, Dubois, Howard, Lake, 
Marion, St. Joseph, Vanderburgh, Vigo, and Wayne Counties. This SIP 
revision updated facility names, revised formatting, removed sources no 
longer in operation, and revised some emission limits. The State 
submitted air quality modeling analyses that demonstrated that air 
quality will continue to be protected in the five counties where some 
emission limits increased. EPA received one letter containing several 
comments on the proposal. After review of these comments and for the 
reasons discussed below, EPA is approving this SIP revision request.

DATES: This final rule is effective on May 30, 2008.

ADDRESSES: EPA has established a docket for this action under Docket ID 
No. EPA-R05-OAR-2007-1177. All documents in the docket are listed on

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,'' 
``us,'' or ``our'' is used, we mean EPA. This supplementary information 
section is arranged as follows:

I. Background
II. Response to Public Comments
III. What Action Is EPA Taking?
IV. Statutory and Executive Order Reviews

I. Background

    On November 27, 2007, Indiana submitted to EPA draft revised rules 
for parallel processing as revisions to the Indiana SIP for particulate 
matter (PM). Indiana supplemented its submittal with a public hearing 
transcript and additional technical support documents on December 3, 
2007, and submitted final, fully adopted revised rules on February 21, 
2008.
    Indiana's submittal consisted of revisions to 326 Indiana 
Administrative Code (IAC) 6.5, Particulate Matter Emission Limitations 
Except Lake County; and 326 IAC 6.8, Particulate Matter Emission 
Limitations For Lake County. Portions of 326 IAC 6.5 and 6.8 were 
unchanged by the submittal, and therefore they remain a part of the 
Indiana PM SIP as approved on March 22, 2006 (71 FR 14383).
    The revised rules apply to facilities in Clark, Dearborn, Dubois, 
Howard, Lake, Marion, St. Joseph, Vanderburgh, Vigo, and Wayne 
Counties. They include a variety of changes to Indiana's Federally 
approved PM SIP rules, such as: Updates to affected facilities' names 
or emission source identifiers; rule formatting revisions which have no 
effect on numerical emission limits; the removal of emission limits for 
individual emission units which no longer exist or operate; and the 
removal of rules for entire facilities which no longer exist or which 
no longer operate the PM sources that were listed in the previous PM 
SIP. Indiana has increased some PM emission limits for sources in 
Clark, Dubois, Marion, St. Joseph, and Lake Counties. Indiana has also 
tightened PM emission limits at several sources.
    In addition, Indiana relocated the opacity limits and natural gas 
combustion-only restrictions for its Lake County sources to the 
facility-specific sections of the rule. The PM limits and any opacity 
limits and natural gas-only restrictions for each facility are now 
grouped in a single section.
    EPA proposed to approve Indiana's February 21, 2008, SIP revision 
request on March 14, 2008, (73 FR 13813). The public comment period for 
the March 14, 2008, proposed rule ended on April 14, 2008. EPA received 
one comment letter on the March 14, 2008, proposed rule.

II. Response to Public Comments

    EPA received several public comments contained in a letter dated 
April 14, 2008, from the City of Chicago, the People of the State of 
Illinois, ex rel. Lisa Madigan, Attorney General of the State of 
Illinois, Natural Resources Defense Council and Environmental Law and 
Policy Center (Commenters), on behalf of their constituents and 
members. These comments focused solely on the proposed PM10 emission 
limits for BP Products North America, Inc.'s Whiting Refinery in Lake 
County, Indiana (BP).
    Comment: The revised limits for BP should include limits on sulfur 
content. Refinery fuel gas contains more sulfur than natural gas, and 
the sulfur in the fuel will be converted to fine particulate matter in 
the atmosphere. BP should be required to reduce the sulfur content of 
its refinery fuel gas in order to meet the proposed PM10 limit.
    Response: Indiana's February 21, 2008, SIP revision request 
requires the gas-combusting sources at BP to meet a PM10 emission limit 
of 0.0075 pounds per million British Thermal Units (lb/MMBTU), whether 
natural gas or refinery fuel gas is used. BP's Title V permit requires 
testing while refinery gas, which has higher PM10 emissions than 
natural gas, is being combusted. The required compliance test methods, 
Methods 201A and 202, are designed to capture both the filterable and 
condensible PM fractions, including sulfur compounds. An air dispersion 
modeling analysis demonstrated that Indiana's February 21, 2008, SIP 
revision request will maintain the PM10 National Ambient Air Quality 
Standards (NAAQS) in Lake County. Therefore, requiring additional 
reductions in the sulfur content of BP's refinery fuel gas is not 
necessary for Federal approval of this SIP revision request.
    In further support of its contentions concerning fuel sulfur 
content, the commenters cite (and, in some cases, incorporate by 
reference) the following: The Bay Area Quality Management District's 
BACT guideline for refinery process heaters; EPA's RACT/BACT/LAER 
Clearinghouse; South Coast Air Quality Management District Regulations; 
and several permits that contain sulfur content limits more stringent 
than those for the BP refinery. These documents and provisions are not 
germane to the air quality issue addressed by EPA's proposal, i.e., 
whether the proposed emission limits are adequate to maintain the 
NAAQS. See, e.g., Train v. NRDC, 421 U.S. 60 (1975).
    Comment: The AP-42 emission factors for natural gas should be 
updated and the BP limits based on these factors recalculated 
accordingly. The emission factors were last updated in July 1998. The 
stack tests conducted since 1998 would show that the current AP-42 
emission factors are overestimations of particulate matter. The AP-42 
emission factors for natural gas should be updated and the SIP revision 
should not be approved until the BP limits reflect the newer AP-42 
emission factors.
    Response: While IDEM used AP-42 emission factors to set PM10 
limits, the test for approval is whether these limits are sufficient to 
meet the PM10 NAAQS. Such a demonstration has been made by IDEM. EPA 
manages and maintains an AP-42 emissions factor database. User-supplied 
updates to the AP-42 emissions factors for natural gas are welcome, but 
EPA is unaware of any new submissions, including any that would support 
the commenters' suggestion. Indiana used the most recent available 
emission factor as a basis for the PM emission limits for BP's gas 
combustion units in the proposed SIP revision and demonstrated through 
air dispersion modeling that the proposed SIP revision would meet the 
PM10 NAAQS. If the AP-42 emission factors overestimate emissions, as 
the commenters have asserted, then the air dispersion modeling analysis 
would overestimate PM emissions, yielding a conservative analysis, 
i.e., one that overpredicts actual emissions and their impacts.
    Comment: The limits should require the use of EPA test methods 201 
and 202, and BP must be required to install PM continuous emission 
monitoring systems (CEMs) and conduct annual

[[Page 23358]]

stack testing to ensure continuous compliance. The commenters approve 
of the test methods applicable to BP, namely, Methods 201A for 
filterable PM and 202 for condensible PM. In addition, the commenters 
request that EPA approval in writing be required for the ``excessive 
temperatures'' exception justifying use of Method 5; and that 
additional language be added stating that alternative methods will only 
be allowed if EPA determines in writing that the listed methods are 
otherwise shown to be technologically infeasible and the proposed 
alternatives are substantially comparable to the listed methods. The 
public should have an opportunity to submit comments on any proposed 
alternative method before EPA issues a written approval. In addition, 
the limits should specify an averaging time, unless the intent is that 
the limit be met on an instantaneous basis.
    EPA Response: The PM test methods applicable to BP require the use 
of Method 201A for determining filterable particulate matter and Method 
202 for determining condensibles. EPA's approval in writing is not 
necessary to allow use of Method 5 in lieu of Method 201A for the 
excessive temperature exception, because Method 5 measures all 
filterable PM, not just PM10, and is therefore a more stringent 
requirement. In fact, Method 5 in combination with Method 202 would 
likely result in higher results than Method 201A with Method 202. EPA 
agrees that an alternative test method would only be allowed if the 
existing method is infeasible for a particular application, in which 
case the most appropriate method would be used. Such technical testing 
issues are not typically subject to public notice. An averaging time is 
not specified because these limits must be met on an instantaneous 
basis. Both EPA and IDEM are authorized to require stack testing when 
appropriate.
    CEMs are not appropriate because they only measure filterable PM 
emissions which, as the commenters have stated, only represent a 
fraction of the PM emissions.
    Comment: Indiana has failed to adequately address controlling PM10 
emissions from flares in general. Flares can be significant sources of 
particulate emissions. EPA should consider whether the proposed SIP 
revision reflects all applicable requirements that could control 
particulate emissions from flares at the BP facility.
    Response: Flares are an insignificant source of PM10 emissions 
(contributing less than one percent of BP's PM10 emissions) and 
therefore, are not included in Indiana's PM10 SIP. Flares operate at 
high temperatures and their emissions are released at elevated heights. 
These factors result in efficient combustion and increased dispersion, 
both of which minimize the ambient impact of any resulting PM 
emissions. Because of these characteristics, EPA does not anticipate 
that the emissions from the BP flares would be significant contributors 
to ambient PM concentrations.
    In addition, it is not feasible to establish PM limits for flares 
because they are not generally amenable to testing, as well as for 
safety reasons. It should also be noted that the Indiana SIP contains 
opacity regulations which apply to flares and which can be easily 
enforced. See 326 IAC 5-1-2(2)(B).
    Indiana's February 21, 2008 submittal did not contain PM10 control 
requirements for flares at the BP refinery and they are therefore not 
addressed in this final approval. EPA finds this omission acceptable 
for the reasons stated above.

III. What Action Is EPA Taking?

    EPA is approving Indiana's February 21, 2008, PM SIP revision 
request, consisting of revisions to 326 IAC 6.5 and 326 IAC 6.8.
    On March 27, 2008, Indiana provided an updated copy of 326 IAC 6.5 
and 326 IAC 6.8 to EPA. This copy includes three State corrections. In 
the proposed rule, at 73 FR 13815, EPA stated that Indiana was planning 
to correct an error in the units of the PM emission limit for Kimball 
Office-Borden (326 IAC 6.5-2-8). Indiana filed a correction notice to 
correct the error on February 29, 2008. It was posted in the Indiana 
Register on March 12, 2008. On February 5, 2008, Indiana filed a 
correction notice to correct the PM emission limit units for Accucast 
Technology, LLC (326 IAC 6.5-7-14). A copy of this correction notice 
was included in Indiana's February 21, 2008, submittal and the 
correction was noted in EPA's March 14, 2008, proposed rule at 73 FR 
13817. Indiana's March 27, 2008, submittal also incorporates a third 
correction notice, which amended minor typographical errors. This 
correction notice was filed on January 31, 2008, and posted in the 
Indiana Register on February 20, 2008. A copy of this correction notice 
was included in Indiana's February 21, 2008, submittal.
    Additionally, as a clarification to EPA's proposal, we noted that 
Indiana's rules were for PM measured as particles with an aerodynamic 
diameter less than or equal to ten microns in diameter (PM10) for all 
counties. However, only Lake County is covered by PM10 limits and the 
remaining counties are covered by PM limits. Although the SIP 
regulations for sources outside of Lake County are expressed as PM, the 
State's and EPA's analyses focused on PM10, a subset of PM.
    EPA is approving revisions to 325 IAC 6.5, Particulate Matter 
Emission Limitations Except Lake County, at 326 IAC 6.5-2, Clark 
County; 326 IAC 6.5-3, Dearborn County; 326 IAC 6.5-4, Dubois County; 
326 IAC 6.5-5, Howard County; 326 IAC 6.5-6, Marion County; 326 IAC 
6.5-7, St. Joseph County; 326 IAC 6.5-8, Vanderburgh County; 326 IAC 
6.5-9, Vigo County; and 326 IAC 6.5-10, Wayne County.
    EPA is also approving revisions to 326 IAC 6.8, Particulate Matter 
Emission Limitations For Lake County, at 326 IAC 6.8-1-1, General 
Provisions, Applicability; 326 IAC 6.8-1-5, Control strategies; 326 IAC 
6.8-1-7, Scope; 326 IAC 6.8-2, Lake County: PM10 Emission Requirements; 
326 IAC 6.8-4-1, Lake County: Opacity Limits; Test Methods; 326 IAC 
6.8-8-1, Lake County: Continuous Compliance Plan, Applicability; 326 
IAC 6.8-9-3, Lake County: PM10 Coke Battery Emission Requirements, 
Emission limitations; and 326 IAC 6.8-10-1, Lake County: Fugitive 
Particulate Matter, Applicability.
    The following portions of 326 IAC 6.5 were repealed and are no 
longer a part of the Indiana PM SIP: 326 IAC 6.5-2, Clark County, 
sections 2, 3, 5, 6, 7, 10, 11, and 12; 326 IAC 6.5-3, Dearborn County, 
sections 6 and 9; 326 IAC 6.5-4, Dubois County, sections 7, 8, 11, 12, 
13, 14, 20, 22, and 23; 326 IAC 6.5-5, Howard County, sections 3, 4, 6, 
7, 8, 9, 12, 13, 14, and 15; 326 IAC 6.5-6, Marion County, sections 4, 
6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 17, 19, 20, 21, 24, 27, 29, 30, 32, 
and 36; 326 IAC 6.5-7, St. Joseph County, sections 2, 3, 4, 5, 7, 8, 9, 
12, 15, 17, 19, and 20; 326 IAC 6.5-8, Vanderburgh County, sections 2, 
3, 4, 5, 6, 7, 8, 9, 10, and 15; 326 IAC 6.5-9, Vigo County, sections 
2, 3, 4, 5, 6, 7, 9, 12, 14, 16, 18, 19, and 20; and 326 IAC 6.5-10, 
Wayne County, sections 4, 7, 8, 10, 17, 18, and 19. EPA is approving 
their removal from the Indiana PM SIP, as discussed in the March 14, 
2008, proposed rule.
    The following portions of 326 IAC 6.8 were repealed and are no 
longer a part of the Indiana PM10 SIP: 326 IAC 6.8-2, Lake County: PM10 
Emission Requirements, sections 3, 5, 10, 11, 12, 15, and 23; 326 IAC 
6.8-3, Lake County: Opacity Limits; Exceptions to 326 IAC 5-1-2; 326 
IAC 6.8-5, Lake County: Opacity Continuous Emissions Monitors; 326 IAC 
6.8-6, Lake County: Combustion Sources; Natural Gas; and 326 IAC 6.8-7, 
Lake County: Site-Specific Control Requirements. EPA is

[[Page 23359]]

approving their removal from the Indiana PM10 SIP, as discussed in the 
March 14, 2008, proposed rule.
    In addition, please note that for purposes of clarity, EPA is also 
including provisions currently in Indiana's PM SIP that it has 
previously approved.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely approves state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     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);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
    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 action 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. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    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 June 30, 2008. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action 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).)
