or "our" refer to EPA. This section provides additional information by addressing the following questions: I. What is being addressed in this document? II . What revisions is EPA approving? III . What action is EPA taking? IV. What action,is EPA not taking? V. Statutory and Executive Order Reviews. I. What is being addressed in this document? The State requested EPA approval of the 2009 revisions to the local agency's Rules and Regulations, Chapter V, "Air Pollution," as a revision to the SIP. In order for the local program's "Air Pollution" rules to be incorporated into the Federally-enforceable SIP, on behalf of the local agency, the State must submit the formally adopted regulations and control strategies, which are consistent with State and Federal requirements, to EPA for inclusion in the SIP. The regulation adoption process generally includes public notice of a public comment period and a public hearing, and formal adoption of the rule by the State authorized rulemaking body. In this case that rulemaking body is the local agency. After the local agency, formally adopts the rule, the local agency submits the rulemaking to the State, and then the State submits the rulemaking to EPA for consideration for formal action (inclusion of the rulemaking into the SIP) . EPAmust provide public notice

and seek additional public comment regarding the proposed Federal action on the State's submission. EPA received the request fromthe State to adopt the 2009 local air agency rule revisions into the SIP on September 14, 2009. The revisions were adopted by the local agency on July 28, 2009, and were effective August 6, 2009. EPA is approving the requested revisions to the Iowa SIP. The State's request specifically excluded Article VI, subsections 5-16 (n), (o), (p), andArticle VIII fromconsideration by EPA. II . What revisions is EPAapproving? EPA is approving the 2009 revisions to the Polk County Board of Health Rules and Regulations, Chapter V, "Air Pollution." The local agency routinely revises its "Air Pollution" regulations to be consistent with the Federallyapproved Iowa Administrative Code. The local agency's "Air Pollution" rules were revised as follows: Article I, section 5-1 was revised to include cross references to approved State rules. Section 5-2 of the same Article was revised to include amended definitions of "Allowable emissions," "EPA reference method," "Disaster," "Mobile Internal Combustion Engine," and "Volatile Organic Compounds" (VOCs) . These revisions are consistent with State and Federal regulations. 

### Article II, section 5-4was revised to include a cross6

reference to the existing State rule, 567 IAC 23.1(2) which outlines NewSource Performance Standard data reporting requirements and responsibilities. This revision is consistent with State and Federal regulations. Article III, section 5-7 was amended to include revisions to "Open Burning" regulations. The revisions include the addition of a cross reference to the existing State rules in 567 IACChapter 23 explaining that the burning of any structure or demolished structure shall be in accordance with 40 CFR 61.145, the National Emission Standards for Hazardous Air Pollutants (NESHAPs) "Standard for Demolition and Renovation" for asbestos control . This revision is consistent with State and Federal regulations. Article IV, section 5-10was revised to include a cross reference to the existing State rule at 567 IAC 29.1, the Federal method for visual determination of opacity of emissions. This revision is consistent with State and Federal regulations. Article VII, subsections 5-18 (a)(3), 5-18(b)(5)(i) and 5- 18(b)(7) are revised to include cross references to existing State rules in 567 IACChapter 25. A revision to 5-18(b)(7) also includes the adoption date of the most recent Federally promulgated Acid Rain continuous emissions monitoring requirements. These revisions are consistent with State and Federal regulations.7

Article IX, subsections 5-23(1), 5-23(2), and 5-23(3) were revised to include methods for the containment and control of fugitive dust, and subsections 5-23(7) and 5-23(8) were added to include methods for the containment and control of fugitive dust. Changes to Section 5-25 clarify that no person shall cause, allow, or permit fugitive dust material to become airborne in such quantities and concentrations that it remains visible in the ambient air, or is deposited beyond the lot line of the property on which it originates. These revisions are consistent with State regulations and Federal requirements. The local agency also added language to subsection 5-26(1) which explains activities that are considered by the local agency as "ordinary travel", which is exempted fromthe fugitive dust restrictions. This is a clarification of the exemption and does not affect the stringency of the restriction. Article X, section 5-33, and subsections 5-33(9) and 5- 39(a)(4) were revised to include cross references to approved State and Federal regulations. Subsections 5-33(17) and 5- 39(a)(11) were revised to include a construction and operating permit exemption threshold for retail gasoline and diesel fuel handling facilities. The local agency revised the exemption to include only those facilities with a throughput of less than 10,000 gallons per month (based on thirty-day rolling average usage records) . The local agency retained the right to review

project plans to substantiate the permit exemption to determine that individual sources qualify for the exemption andwould not adversely impact air quality. The local agency made this revision as it is more stringent than the existing SIP-approved exemption and is aligned with 40 CFR Part 63 subpart CCCCCC. The Iowa Administrative Code currently does not provide for exemptions for retail gasoline stations of any size so that all sources in the source category in Polk County remain subject to the state permitting rule. In any event, the revision addressed in this rulemaking in the county rule makes the exemption more stringent, and is therefore approvable. Also in Article X, subsections 5-33(55) and 5-39(a)(48) were revised to add a construction and operating permit exemption for cold solvent cleaning machines that are not inline cleaning machines. Subsections 5-33(56) and 5-39(a)(49) were revised to add a construction and operating permit exemption for emissions frommobile agricultural and construction internal combustion engines that are operated only for repair or maintenance purposes at equipment repair shops or equipment dealerships. Subsection 5-35(d) was revised to reduce the amount of time the owner or operator has to notify the local programprior to the movement of portable equipment for which an operating permit has been issued. The notification time was reduced from30 to 14 days. Subsections 5-36(1)(a) and 5-

### 9

36(1)(a)(1) were revised to clarifywhat the owner or operators' responsibilities are when applying for a conditional operating permit. These revisions are consistent with SIP-approved State regulations. 

### Section 5-49 was added toArticle X to allowfor electric utilities in Polk County to operate generators at a utility substation, with a total combined capacity not to exceed 2 megawatts in capacity, for a period of not longer than 10days andonly for the purpose of providing electricity generation in theevent of a sudden and unforeseen disaster that has disabled standard transmission of electricity to the public. EPA previously approved this allowance in a statewide rule after EPA determined that this allowance would result in insignificant emissions increases. We believe the Polk County revision is also approvable. III . What action is EPA taking? EPA is approving these revisions to the Polk County Board of Health Rules and Regulations, Chapter V, Air Pollution. These changes are consistent with the Federally-approved Iowa SIP. The state submittal has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submittal also satisfied the completeness criteria of 40 CFR part 51, appendix V. The revisions meet the substantive SIP

### 10

requirements of the CleanAirAct (CAA), includingsection 110 and implementing regulations. EPA is processing this action as a direct final action because the revisions make changes to the existing rules which are noncontroversial . Therefore, we do not anticipate any adverse comments. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed fromthe remainder of the rule, EPAmay adopt as final those parts of the rule that are not the subject of an adverse comment. IV. What action is EPAnot taking? The State requested that EPAtake action to approve the local agency's revisions to Article XVI section 5-75. Section 5-75 outlines the local agency's enforcement of criminal and civil penalties. As EPA does not rely on the local agency's authority, but relies on its own authority, to implement and enforce the requirements of the CAA, EPA is not taking action on the requested revisions to Article XVI section 5-75. 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 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 of11

the CAA. Accordingly, this action merely approves state lawas 

### meeting Federal requirements anddoes 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 FR51735, 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 FlexibilityAct (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 ReformAct of 1995 (Public Law104-4) ; " does not have Federalismimplications 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) ;12

" is not subject to requirements of Section 12(d) of the National Technology Transfer andAdvancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and 

### " does not provide EPAwith thediscretionary 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 ReviewAct, 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. EPAwill 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

### 13

States prior to publication of the rule in the Federal Register. Amajor 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 CAA, petitions for judicial reviewof this action must be filed in the United States Court of Appeals for the appropriate circuit by [FEDERAL REGISTER 

### OFFICE: insert date 60 days fromdate of publicationof this document in the Federal Register]. 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 reviewnor does it extend the time within which a petition for judicial reviewmay be filed, and shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today's Federal Register, rather than file an immediate petition for judicial reviewof this direct final rule, so that EPA can withdrawthis direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. (2) .) (See section 307(b)14
