Proposed rule. 

# SUMMARY:

                        EPA is proposing to approve revisions to the Kentucky State Implementation Plan (SIP), submitted by the Commonwealth of Kentucky, through the Kentucky Department of Air Quality (KDAQ), on September 6, 2005. The revisions include changes to Kentucky Administrative Regulations (KAR) Title 401, Chapters 50:045, “Performance tests,” and 63:005, “Open burning.” The changes included in the proposed SIP revisions are part of Kentucky's strategy to attain and maintain the 8-hour ozone and fine particulate (PM2.5) national ambient air quality standards (NAAQS) by reducing emissions of PM2.5                         and precursors to ozone. EPA is proposing to approve Kentucky's SIP revisions pursuant to section 110 of the Clean Air Act (CAA).

# SUPPLEMENTARY INFORMATION:

## I. Summary of Proposed Action 

On September 6, 2005, KDAQ submitted to EPA proposed SIP revisions for review and approval into the Kentucky SIP. The proposed revisions include changes made by the Commonwealth of Kentucky to its performance test and open burning regulations, found at 401 KAR 50:045 and 401 KAR 63:005, respectively. These changes became state effective on July 13, 2005. The rule changes were made to update Kentucky's regulations on performance testing, and to establish additional requirements to reduce emissions from open burning. 

Kentucky's performance testing rule, 401 KAR 50:045, provides guidelines for the methodology, testing conditions, and reporting requirements necessary for sources to demonstrate compliance with air emissions limitations and standards. Corresponding federal rules on performance tests, promulgated by EPA pursuant to Part D of title I of the CAA (“Plan Requirements for Nonattainment Areas”), are found at 40 Code of Federal Regulations (CFR) part 63. These federal rules were incorporated by reference into the Kentucky SIP on July 12, 1982 (47 FR 30059). Kentucky recently made changes to its rules such that the rule previously containing the performance test requirements, 401 KAR 50:016, is being repealed, and the performance test requirements from that rule are being placed in 401 KAR 50:045. Because 401 KAR 50:016 was not part of the Kentucky SIP, EPA is not addressing Kentucky's repeal of that rule. Rather, today's action proposes approval of 401 KAR 50:045, which now includes the performance testing provisions previously found in 401 KAR 50:016. As part of the movement of the performance test provisions to 401 KAR 50:045, Kentucky made minor, non-substantive, changes to the rule. Kentucky's performance testing rule is consistent with applicable federal law. The proposed SIP revision regarding performance testing is therefore approvable pursuant to section 110 of the CAA. 

Kentucky's open burning rule, 401 KAR 63:005, establishes restrictions on open burning designed to reduce emissions from such activities. This rule was first approved into the Kentucky SIP on July 12, 1982 (47 FR 30059). The rule is structured such that open burning in general is prohibited unless specified conditions are met. The conditions are described in sections 3 and 4 of 401 KAR 63:005; section 5 also includes such restrictions but applies only to open burning for fire training. Kentucky revised its open burning rule, effective July 13, 2005, in order to better control open burning of potentially hazardous household garbage. This rule is part of Kentucky's strategy to attain and maintain the 8-hour ozone and PM2.5 NAAQS by reducing emissions of PM2.5 and ozone precursors resulting from open burning. 

The open burning rule changes made by Kentucky are intended to protect air quality in areas where open burning is occurring. The rule changes clarify instances when open burning of household garbage is permitted and allow open burning of wood waste or clean lumber by municipal and county governments. The changes added definitions for “clean lumber,” and “land clearing,” and modified the definition of “household rubbish.” The modification made to the definition of “household rubbish” now excludes from the definition any “other hazardous waste materials.” The changes also included a new section, section 5, which specifically addresses restrictions to open burning for fire training. Among the new requirements are that substances being burned for training purposes not contain hazardous or asbestos containing materials (see, sections 5(3) and 5(4)). The changes made to section 5 are at least as stringent as the previous regulation. As a result, the SIP revision is approvable pursuant to section 110 of the CAA. 

## II. Proposed Action 

                    EPA is proposing to approve the SIP revisions submitted by Kentucky on September 6, 2005. The revisions include changes to two state rules: 401 KAR 50:045, “Performance tests,” and 401 KAR 63:005, “Open burning.” The SIP revisions include changes to rules that are part of Kentucky's strategy to attain and maintain the NAAQS by reducing emissions of particulate matter, volatile organic compounds, nitrogen oxides, and hazardous air pollutants.                           ( print page 1956)    

## III. Statutory and Executive Order Reviews 

                    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed 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 proposed 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 proposed action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this 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 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 (65 FR 67249, November 9, 2000). This proposed action also does not have Federalism implications because it does 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 proposed action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. As a result, it does 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 is not economically significant. 

                    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.*).
