Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Particulate Matter Limitations for Coating Operations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a revision to the Indiana State Implementation Plan (SIP) under 
the Clean Air Act (CAA). The particulate matter (PM) rules that were 
submitted consist of emission control requirements for coating 
operations along with exemptions from certain coating operations that 
produce minimal PM emissions. EPA is also proposing to take no action 
on one section submitted by

[[Page 21422]]

Indiana, as it pertains to a definition in an unapproved portion of 
Indiana's Title V regulations. Indiana submitted this request to 
approve PM rules on April 27, 2012.

II. What is the background for this action?

    On April 27, 2012, Indiana submitted a request to revise its SIP 
under the CAA to incorporate the revised rules. Specifically, Indiana 
requested that EPA approve the following sections as part of the SIP: 
326 Indiana Administrative Code (IAC) 6-3-1, 326 IAC 6.5-1-1, 326 IAC 
6.5-1-2, 326 IAC 6.5-1-5, 326 IAC 6.5-1-6, 326 IAC 6.8-1-1, 326 IAC 
6.8-1-2, 326 IAC 6.8-1-5, and 326 IAC 6.8-1-6. These provisions would 
replace requirements that EPA has previously been approved into the 
Indiana SIP. EPA approved 326 IAC 6-3 on July 25, 2005 (70 FR 42495). 
EPA approved the addition of 326 IAC 6.5 and 326 IAC 6.8 into the 
Indiana SIP on March 22, 2006 (71 FR 14383). EPA approved subsequent 
revisions of sections of 326 IAC 6.5 and 326 IAC 6.8 into the Indiana 
SIP on April 30, 2008 (73 FR 23356).
    Article 6 of 326 IAC contains Indiana's PM rules. Article 6.5 of 
326 IAC contains statewide PM emission limitations except for Lake 
County and Article 6.8 of 326 IAC provides the PM emission limits for 
Lake County sources.
    The language Indiana added in 326 IAC 6.5-1-2(h) and 326 IAC 6.8-1-
2(h) is very similar to the language in 326 IAC 6-3-2(d). As noted, EPA 
approved 326 IAC 6-3 including 326 IAC 6-3-2(d) on July 25, 2005 (70 FR 
42495).

III. What is EPA's analysis?

    Indiana made the same revisions to the rules of 326 IAC 6.5-1 and 
326 IAC 6.8-1. Thus, EPA analyzed the revisions to the same rules and 
sections of 326 IAC 6.5-1 and 326 IAC 6.8-1 together and concluded that 
the changes were acceptable in both regulations.

A. Applicability: 326 IAC 6-3-1; 326 IAC 6.5-1-1; 326 IAC 6.8-1-1

    In 326 IAC 6-3-1, Indiana revised two sections. Indiana submitted a 
revision to 326 IAC 6-3-1(b)(13) to reference the definition of trivial 
activities as found in

[[Page 21423]]

326 IAC 2-7-1, part of Indiana's Title V rules. The definition of 
``trivial activities'' is not currently in either Indiana's Title V 
permitting program or SIP. For that reason, EPA is proposing to take no 
action at this time on the revision of 326 IAC 6-3-1(b)(13). It should 
be noted that the term ``trivial activities'' is not contained in any 
of the regulations that EPA is approving in this action.
    Indiana moved a phrase in 326 IAC 6-3-1(c) to improve clarity. 
There is no material change from what is approved into the Indiana SIP 
and thus EPA is proposing approval of the 326 IAC 6-3-1(c) revision.
    Indiana revised both 326 IAC 6.5-1-1 and 326 IAC 6.8-1-1 by adding 
a new subsection (c) that exempts certain surface coating operations 
from PM emission limits. The exempt processes are dip coating, roll 
coating, flow coating, and brush coating. The primary emissions of 
concern from surface coating are the volatile organic compound 
emissions that arise from solvent evaporation. PM emissions from 
coatings primarily are from overspray, the fine coating droplets that 
are not applied as desired. Overspray, the portion of coating solids 
that does not land on the item and is exhausted as PM emissions, is 
common on spray coating operations but is not an issue with the four 
exempt coating methods: Dip coating, roll coating, flow coating, and 
brush coating. EPA expects minimal PM emission will occur from the 
exempted coating methods and thus is proposing to approve the 
exemptions.
    Indiana also included in 326 IAC 6.5-1-1(c) and 326 IAC 6.8-1-1(c) 
an exemption from the PM limits for facilities that use less than five 
gallons of coating per day. EPA is satisfied that facilities that use 
less than five gallons of coating daily will have de minimis PM 
emissions because of the limited potential for overspray. Thus, EPA is 
proposing to approve the exemptions from PM limits in these cases.
    The remaining changes to 326 IAC 6.5-1-1 and 326 IAC 6.8-1-1 are 
simply updates to the section references from the version approved into 
the Indiana SIP. For example, 326 IAC 6.5-1-1(c) became 326 IAC 6.5-1-
1(d) and 326 IAC 6.8-1-1(c) became 326 IAC 6.8-1-1(d) following the 
addition of a new section (c) in both articles.

B. Particulate Emission Limitations, Modifications by Commissioner: 326 
IAC 6.5-1-2; 326 IAC 6.8-1-2

    Indiana also revised both 326 IAC 6.5-1-2 and 326 IAC 6.8-1-2. 
Indiana made revisions by rewording and moving phrases to 326 IAC 6.5-
1-2(a), (b), (c), (d), and (e). Identical revisions were made to 326 
IAC 6.8-1-2(a), (b), (c), (d), and (e). The changes to the revised 
sections are insubstantial when compared to the approved sections.
    Indiana added requirements for PM emission controls on surface 
coating operations in 326 IAC 6.5-1-2(h) and 326 IAC 6.8-1-2(h). 
Sources are required to operate a dry particulate filter, a water wash, 
or an equivalent PM control device. If overspray occurs, 326 IAC 6.5-1-
2(h)(2) and 326 IAC 6.8-1-2(h)(2) require the source to inspect and 
repair the control device or adjust operations to eliminate the 
overspray within four hours. The source must keep a record of its 
action to remedy the overspray. Select sources are allowed under 326 
IAC 6.5-1-2(h)(3) and 326 IAC 6.8-1-2(h)(3) to follow the control 
device inspection and repair requirements in its permit if overspray is 
detected in place of the general control device inspection and repair 
requirements in 326 IAC 6.5-1-2(h)(2) and 326 IAC 6.8-1-2(h)(2). As 
usual, the most stringent requirement applies and thus the permit 
requirements must be at least as stringent as the requirements in 326 
IAC 6.5-1-2(h)(2) and 326 IAC 6.8-1-2(h)(2). EPA finds that the 
addition of the PM emission control requirement for coating operations 
to be satisfactory and thus is proposing approval. The requirements of 
these sections will require any sources lacking the requirement to take 
corrective action once overspray is detected. Overspray is sign that 
the control equipment is not properly operating.
    Indiana further added, at 326 IAC 6.5-1-2(h)(4) and 326 IAC 6.8-1-
2(h)(4), a provision that if a facility increases its use of coatings 
to exceed five gallons per day, it is no longer exempt from the 
regulation; and Indiana must require appropriate PM emissions controls, 
even if the source subsequently reduces its coating use back to using 
less than five gallons of coating per day. Indiana's Federally approved 
permitting rules require each source to keep records for ensuring 
compliance with applicable emission limits. Therefore, each source will 
be required in its permits (title V or Federally enforceable state 
operating permit) to maintain records of its coating usage to establish 
applicability according to the criteria in 326 IAC 6.5-1-2(h)(4) or 326 
IAC 6.8-1-2(h)(4).
    Indiana renamed 326 IAC 6.5-1-2(h) to 326 IAC 6.5-1-2(i) and 326 
IAC 6.5-1-2(i) to 326 IAC 6.5-1-2(j) following the addition of the new 
326 IAC 6.5-1-2(h). Identical section renaming was also made in 326 IAC 
6.8-1-2. EPA is proposing to approve the addition of 326 IAC 6.5-1-2(h) 
and 326 IAC 6.8-1-2(h) along with the revision to the other sections of 
326 IAC 6.5-1-2 and 326 IAC 6.8-1-2 into the Indiana SIP.

C. Control Strategies and SIP Revisions: 326 IAC 6.5-1-5; 326 IAC 6.5-
1-6; 326 IAC 6.8-1-5; 326 IAC 6.8-1-6

    References to other rule sections in 326 IAC 6.5-1-5, 326 IAC 6.5-
1-6, 326 IAC 6.8-1-5, and 326 IAC 6.8-1-6 were updated to reflect the 
revised section and subsection numbering in the referenced rules. The 
revisions improve the clarity of the rules with clear language and 
current references without changing the PM limits or any requirements 
that have previously been approved. 326 IAC 6.5-1-6 and 326 IAC 6.8-1-6 
specifically require that any exemptions or provisions granted by the 
state in sections 2(a), 2(g), 2(i), 2(j), 4, and 5 of the rule shall be 
submitted to EPA as revisions to the SIP. Thus, EPA is proposing to 
approve the modifications to 326 IAC 6.5-1-5, 326 IAC 6.5-1-6, 326 IAC 
6.8-1-5, and 326 IAC 6.8-1-6 into the Indiana SIP.

IV. What action is EPA proposing to take?

    EPA is proposing to approve into the Indiana SIP revisions to PM 
rules submitted by Indiana on April 27, 2012. These revisions add PM 
control requirements for coating operations. The other primary 
revisions provide PM limit exemptions for coating operations that 
produce minimal PM emissions. The remaining modifications are clerical 
revisions that increase the lucidity of the rules without altering the 
PM limits.
    Specifically, EPA is proposing approval of 326 IAC 6-3-1(c), 326 
IAC 6.5-1-1, 326 IAC 6.5-1-2, 326 IAC 6.5-1-5, 326 IAC 6.5-1-6, 326 IAC 
6.8-1-1, 326 IAC 6.8-1-2, 326 IAC 6.8-1-5, and 326 IAC 6.8-1-6. EPA is 
proposing to take no action on 326 IAC 6-3-1(b).

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA 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 CAA. 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

[[Page 21424]]

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 CAA; 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.
