   1.          Identification of the Information Collection Request

1(a)	Title of the Information Collection

	The title of the Information Collection Request (ICR) is "Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards (NAAQS) State Implementation Plan Requirements (SIP) Rule," ICR number 2258.03, and OMB Control Number 2060-0611, expiration date:  the earlier of May 31, 2018 or the date of the finalization of the new ICR proposed on March 23, 2015 (55 FR 15340).

1(b)	Abstract/Executive Summary

   The EPA has established a suite of PM2.5 ambient air quality standards based on evidence from numerous health studies demonstrating that serious health effects are associated with exposures to elevated levels of PM2.5. Estimates show that attainment of the PM2.5 standards would result in tens of thousands fewer premature deaths each year, tens of thousands fewer hospital admissions each year, and hundreds of thousands fewer doctor visits, absences from work and school, and respiratory illnesses in children annually. The EPA initially established annual and 24-hour PM2.5 standards in 1997. The 24-hour standard was subsequently revised in 2006, and the annual standard was revised in 2012.
   
   The EPA is planning to submit an information collection request (ICR), "Fine Particulate Matter (PM2.5) NAAQS Implementation Rule (Renewal)" (EPA ICR No. 2258.04, OMB Control No. 2060-0611) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act (44 U.S.C. 3501 et seq.). Before doing so, the EPA is soliciting public comments on specific aspects of the proposed information collection as described below. This is a proposed renewal of an existing ICR, which was originally established with the EPA's now-remanded 2007 final rule addressing implementation-related requirements for the 1997 PM2.5 NAAQS. On March 23, 2015,  the EPA proposed a new ICR associated with its Notice of Proposed Rulemaking that would replace the remanded 2007 PM2.5NAAQS Implementation Rule. Until that ICR is finalized, the existing ICR will remain in effect, subject to this proposed renewal. 
   
   The EPA is proposing in the PM2.5 NAAQS SIP Requirements Rule to describe the Clean Air Act (CAA) requirements that must be met by states with nonattainment areas required to develop attainment plans for attaining and maintaining the NAAQS. The intended effect of the SIP Requirements Rule is to provide clarity to state air agencies regarding their planning obligations. Only states with nonattainment areas are required to submit SIPs that meet the requirements of the rule. 
	
   The information collection activities in PM2.5 NAAQS SIP Requirements Rule  proposed rule have been submitted for approval to OMB under the Paperwork Reduction Act (PRA). The PRA requires the EPA to assess the administrative burden (in hours and dollars) for state and local air agencies to develop plans to attain the PM2.5 NAAQS, and for the EPA to review and take action on such plans.   The current burden was estimated in the ICR (Reference number 201203-2060-009) concluded on 4/9/2012. This ICR is a renewal of the previous ICR approved estimating the burden for the 6 areas remaining in nonattainment for the 2006 PM2.5 NAAQS as compared to 31 nonattainment areas initially designated for that NAAQS. In addition, one of the six areas (San Joaquin Valley, CA) remains nonattainment for the 1997 PM2.5 NAAQS.
   
   With respect to ongoing implementation of the 1997 and 2006 PM2.5 standards, the EPA estimates the total administrative burden for state air agencies with nonattainment areas during the ICR extension period to be 126,000 hours, and the estimated administrative burden for EPA to be 6,900 hours. In this analysis, fifty percent of the hours are assumed to be expended in the first year, with the remaining hours evenly divided between the second and third years of the ICR period. 
   
   For the remaining 1997 and 2006 PM2.5 nonattainment burden, the present value of the total additional costs for state air agencies, the respondents, estimated at $7.6 million for the extension period. On an equivalent annual basis, that is approximately $2.5 million per year. 
   
   For the remaining 1997 and 2006 PM2.5  nonattainment burden, the present value of the Agency administrative cost burden is estimated at $0.8 million dollars for the ICR extension period. This is roughly equivalent to $0.3 million per year.  
   
   The incremental administrative burden for the areas and activities covered by this ICR is mitigated by the fact that these state air agencies all have experience with developing SIPs for previous revisions submitted for this and previous PM2.5 NAAQS. 

   2.          Need For and Use of the Collection
   2(a)   Need/Authority for the Collection

   The CAA, which was last amended in 1990, requires the EPA to establish NAAQS for air pollutants that may reasonably be anticipated to endanger public health or welfare, and which result from numerous or diverse sources. On July 18, 1997, the EPA revised the NAAQS for particulate matter to add new standards for fine particulate matter (particles of solid and liquid material less than 2.5 microns in aerodynamic diameter), using PM2.5 as the indicator. The EPA established health-based (primary) annual and 24-hour standards for PM2.5 (62 FR 38652). The annual standard was set a level of 15 micrograms per cubic meter, based on the 3-year average of annual mean PM2.5 concentrations. The 24-hour standard was set a level of 65 micrograms per cubic meter, based on the 3-year average of the 98[th] percentile of 24-hour concentrations. The welfare-based secondary standards were established identical to the primary standards.
    
   The initial PM2.5 NAAQS Implementation Rule was proposed November 1, 2005 (70 FR 65983) and was promulgated on April 25, 2007 (72 FR 20586). The preambles to the proposed and final rules addressed the administrative burden in general terms. The preamble to the final rule stated that an ICR would be prepared. The first ICR (No. 2258.01) covered a period from April 5, 2008 through April 4, 2011. A extension without change of the approved ICR was approved through April 30, 2012.
   
   On October 17, 2006, the EPA revised the NAAQS for fine particles. The EPA established new primary and secondary 24-hour standards for PM2.5 (71 FR 61144). The 24-hour standards were set a level of 35 micrograms per cubic meter, based on the 3-year average of the 98[th] percentile of 24-hour concentrations. The annual standard remained unchanged at a level of 15 micrograms per cubic meter, based on the 3-year average of annual mean PM2.5 concentrations. 
   
   On December 14, 2012, the EPA revised the NAAQS for fine particles. The EPA established a new primary annual PM2.5 standard at a level of 12 micrograms per cubic meter, based on the 3-year average of annual mean PM2.5 concentrations (78 FR 3086). The 24-hour standards remained unchanged at a level of 35 micrograms per cubic meter, based on the 3-year average of the 98[th] percentile of 24-hour concentrations. 
   
   On January 4, 2013, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) remanded the 2007 PM2.5 NAAQS Implementation Rule, concluding that the agency had erred in implementing the PM2.5 NAAQS according to only the general nonattainment area planning provisions of subpart 1, part D, title I of the CAA, rather than in accordance with the the PM-specific planning requirements of subpart 4, part D, title I of the CAA and certain general planning provisions in subpart 1. On March 23, 2015, the EPA proposed a new implementation rule (80 FR 15340) consistent with the attainment planning requirements under CAA subparts 1 and 4 of part D, title I, that would apply to ongoing implementation efforts by air agencies in areas designated nonattainment for the 1997, 2006, and most recent 2012 PM2.5 NAAQS. As part of its proposed implementation rule, the EPA also proposed a new ICR to account for the additional cost burden to air agencies developing attainment plans for areas designated nonattainment for the 2012 PM2.5 NAAQS, in addition to the burden associated with plan revisions related to ongoing implementation efforts for the 1997 and 2006 PM2.5 NAAQS. Once final, the new ICR will supersede the existing ICR for which the EPA is proposing renewal in the March 23, 2015 implementation rule action. 
   
   However, in the meantime, while the EPA completes its current rulemaking and finalizes the new ICR, the agency is hereby proposing a renewal of the existing ICR that would continue to apply during this interim period.  The time period covered in the current approved ICR (2258.02) was a 3 year period from May 1, 2012 through April 30, 2015. The time period that was to be covered in this third ICR (2258.03) was anticipated to be a 3 year period from May 1, 2015 through April 30, 2018.  The renewal of the existing ICR period will extend the time period covered until the final approval action of the March 23, 2015 implementation rule.
   

   2(b)	User/Users of the Data 
   
   The data collected from state or local air agency respondents will include the nonattainment SIP elements required by the CAA, many of which are described in more detail in the PM2.5 SIP requirements rule (72 FR 20586). The PM2.5 attainment plan must contain state rules and other requirements designed to achieve the NAAQS by the deadlines established under the CAA. 
   
   The PM2.5 attainment plan(s) to be submitted by the state must include the various requirements in subpart 1, such as:
   
   * Baseline emissions inventory for stationary, mobile, and area emissions sources in the nonattainment area consistent with 40 CFR 51.1008 of the rule.
   * A proposed attainment date consistent with section 51.1004 of the rule. 
   * An attainment demonstration with air quality modeling showing that existing federal and state emissions reduction programs, plus any new emissions reduction programs adopted by the state, will result in expeditious attainment by the attainment date, consistent with section 51.1011 of the rule. The attainment demonstration must meet the requirements of 40 CFR 51.112 and Part 51, Appendix W, and must include emissions inventory projections, modeling results, and emissions reduction analyses on which the state has based its projected attainment date. The attainment demonstration and supporting air quality modeling should be consistent with the EPA's PM2.5 modeling guidance
   * A plan showing that annual emissions reductions will provide for reasonable further progress (RFP) toward attainment of the standard for the period prior to the area's attainment date, consistent with section 51.1012 of the rule; and reporting every 3 years on quantitative milestones showing such progress through the implementation of the attainment plan and associated control measures, consistent with section 51.1013 of the rule. 

   The state air agencies use this information and analysis to fulfill federal obligations under Title I, Subpart D of the Clean Air Act and the PM2.5 Implementation Rule. They also use the attainment demonstrations, RFP, reasonably available control technology (RACT) and reasonably available control mechanisms (RACM) determinations to inform their citizenry, including potentially regulated entities. The potentially regulated entities use this information in assessing future emissions reduction requirements. 
   
   The EPA regional and headquarters offices will use the submitted information in determining the adequacy of the various elements of the PM2.5 attainment plan. After a state submits a SIP with the appropriate technical supporting documentation, the EPA is required under the CAA to approve or disapprove the SIP within 12 months. Emissions reduction regulations developed by the state air agencies become federally enforceable when approved by the EPA.
   
   
   3. Non-Duplication, Consultations, and Other Collection Criteria
   
   3(a)	Non-Duplication
   
As noted in section 2(b) above, the state air agency respondent will submit an attainment plan for each nonattainment area that will need to include a number of separate and unique elements. For example, each attainment plan will need to include a unique RACM/RACT analysis, attainment demonstration, and RFP plan. 
   
   However, there are other activities covered by existing ICRs which complement the elements required in the PM2.5 attainment plan. For example, the existing fine particle monitoring network, covered under a separate, existing ICR, provides essential data for use by state air agencies and the EPA in identifying key categories of emissions and tracking progress toward attainment.
   
   The EPA encourages state air agencies to account for control measures and expected emission reductions from existing regulations and implementation planning processes, such as for the 1997 and 2006 PM2.5 NAAQS, the 2008 ozone NAAQS, the regional haze program, the cross state air pollution rule (CSAPR), and the Mercury and Air Toxics Standards. Taking such steps, where appropriate, may enable state air agencies to reduce the incremental administrative burden associated with this rule and enable identification of control strategies that achieve multi-pollutant environmental progress at a lower cost.

   3(b)	Public Notice Required Prior to ICR Submission to the Office of Management and Budget (OMB)
	This is a renewal of an existing rule-related ICR.  Comments on this ICR will be requested when the ICR renewal is proposed in the Federal Register in May 2015.  The ICR renewal was published for public notice and comments on May XX, 2015  (http://edocket.access.gpo.gov/2015/pdf/2015-XXXX.pdf)
   
   3(c)	Consultations
   
	The EPA is soliciting comment on the proposed renewal of the ICR for the PM2.5 SIP requirements rule. 
   
   3(d)	Effects of Less Frequent Collection
   
	The collections under this rule (as reviewed in section 2.b) are necessary to comply with Clean Air Act requirements and provide assurances that identified levels of emission reductions are adequate to ensure timely attainment and maintenance of the PM2.5 NAAQS. 
   
   3(c) 	General Guidelines 
   
   The reporting and recordkeeping requirements in this proposed rule do not violate any of the regulations promulgated by OMB under 5 CFR part 1320, section 1320.5. This submission meets the current Paperwork Reduction Act guidelines set forth by OMB. Those guidelines reflect the requirements of 5 CFR 1320.6. The PM2.5 NAAQS SIP requirements rule does not require:
      * reporting more than once a year;
      * respondents to participate in a statistical survey;  
      * responses to Agency inquiries in less than 30 days;
      * respondents to receive remuneration for preparation of reports; 
      * records to be kept more than 3 years;
      * manual methods of reporting.
   
   3(f)		Confidentiality
     
	The information requested from the state air agencies to fulfill CAA requirements as described in section 2(b) will rely on emissions levels and control efficiency data provided by certain facilities in the private and public sectors. This information is available from a variety of sources and state air agencies should already have information from emission sources, as facilities should have provided this information to meet other NAAQS SIP requirements, operating permits, and/or emissions reporting requirements. It is the assimilation and analysis of that data (e.g., for RACM/RACT control measure determinations, the attainment demonstration, etc.) that is required by this rule. 
   
	Emissions and control technology information from emissions sources generally does not reveal the details of production processes. But, to the extent that it may, the affected facilities are protected. Specifically, the provision of the emissions and control efficiency information that is confidential, proprietary, and trade secret is protected from disclosure under the requirements of subsections 503(e) and 114(c) of the Clean Air Act.
   
   3(g)	Sensitive Information
   
	The requested PM2.5 SIP requirements rule submissions do not include questions whose answers would require sensitive information.
   
   
   4.0 The Respondents and the Information Requested
   
   4(a)	Respondents and Nonattainment areas
   
   State and local air agencies are the primary respondents under this ICR. Table 1 lists the nonattainment areas and state air agencies with remaining SIP submittals for the 1997 PM2.5 NAAQS and the 2006 PM2.5 NAAQS that potentially could be required during the ICR period. For purposes of this draft analysis, it has been assumed that for the 1997 PM2.5 NAAQS, a revised attainment plan will be required during the ICR period for one nonattainment area.  It also has been assumed that for the 2006 PM2.5 NAAQS, a revised attainment plan will be required during the ICR period for six nonattainment areas. (Note that these assumptions have been made only for the purposes of this draft analysis, and a number of factors and future state or EPA actions could change the assumptions put forth here.) 
   
   Table 1 also includes an estimated 18,000 burden hours for each revised attainment plan  and an estimated total weighted direct and indirect hourly equivalent salary cost of $65.10 per hour. Section 6 provides more details on these estimates.

     4(b)	 	Information Requested

   The information requested under this proposed rule, as described in section 2(b) of this ICR, is required to meet the requirements of the CAA. The implementation framework set forth in the regulation does not adopt a "one-size-fits all" approach to meeting these requirements. This additional flexibility enables the State air agencies to customize, to the extent allowed by the Clean Air Act, their approach to attaining and maintaining the PM2.5 NAAQS.

   Data Items.  The emissions and control efficiency data required for the attainment demonstration, RFP, RACT, and RACM is assumed to have been collected as a result of reporting activities required by other OMB-approved ICRs. For example, the collection of emissions information for many stationary sources is required under other program requirements, such as the Air Emissions Reporting Rule (AERR) Rule (see http://www.epa.gov/ttnchie1/aerr/). In developing PM2.5 SIPs, air agencies are expected to use a range of other readily available data sources, such as existing federal rules that are expected to reduce future emissions of particulate matter precursors, and economic and population growth rates.
    
   Respondents' Activities. The state air agecies will compile and reference the data, set forth the analytical methodology, conduct control technology, emission reduction and air quality modeling analyses, develop initial drafts, hold hearings, adopt rules, regulations, and programs, have discussions with EPA staff as appropriate, refine the draft attainment demonstration as appropriate, adopt the SIP, and formally submit the SIP to the EPA.
   
   Agency Activities. The EPA staff in the regional offices will facilitate timely receipt of the attainment demonstration, RFP, RACT, and RACM requirements by reviewing materials and answering questions from the state air agencies regarding regulatory requirements, potential data sources, analytical tools, the draft attainment demonstration, and other draft SIP elements. The EPA Regional Offices will evaluate the formal SIP submissions and take rulemaking actions to approve or disapprove the SIP revisions. The EPA headquarters staff will facilitate policy coordination and national consistency in the timely review and evaluation of plans from state air agencies around the country. They will also facilitate information flow among the regions and states to promote the development of acceptable demonstrations and SIP submissions.
   
   Reporting Protocols. The dates for plan submissions and milestone reports are as set forth in subpart 4 of Part D of the CAA (sections 188-190), and in the proposed PM2.5 SIP Requirements Rule.
   
   
   5.0 The Information Collected -- Agency Activities, Collection Methodology, and Information Management
     
     5(a)	States, EPA Regional Offices, and EPA Headquarters Offices

	States.  The state air agencies' activities include:

      * Develop baseline emissions inventory and projection year inventory.
      * Conduct analyses of economic and technological feasibility of potential control measures and adopt state rules requiring emission reductions to ensure attainment of the standard "as expeditiously as practicable."
      * Develop and evaluate emissions reduction strategies, and conduct air quality modeling showing that existing federal and state emission reduction programs, plus any new emission reduction programs adopted by the state, will result in expeditious attainment by the attainment date.
      * Develop plans to ensure that future emission reductions will provide for reasonable further progress toward attainment of the standard for the period prior to the area's attainment date. 
   
   	EPA Regional Offices. The regional office activities include:
      * Respond to inquiries from the air agencies and provide guidance on SIP development.
      * Review technical data, analyses, and draft SIP elements developed by the air agencies. 
      * Evaluate the formal SIP submissions and conduct rulemaking actions approving or disapproving the SIP submissions.
   
   	EPA Headquarters.  The EPA headquarters office activities include:
      * Answer questions regarding application and interpretation of rule provisions.
      * Facilitate policy coordination and national consistency in the timely review and evaluation of plans from state air agencies around the country. 
      * Coordinate information flow amongst the regions and states to promote the development of acceptable demonstrations and SIP submissions.

   5(b)	Collection Methodology and Management
   
	The PM2.5 attainment plan submitted by the air agency will set forth the data sources, analytical methods, and the emission reduction and air quality improvement verification procedures used in its development and implementation. 

     5(c)		Small Entity Flexibility

		For an approved ICR, the Agency must demonstrate that it has taken all practical steps to develop separate and simplified requirements for small businesses and other small entities. See 5 CFR 1320.6(h). The proposed PM2.5 NAAQS implementation regulations do not provide a direct administrative burden on small entities.  

      5(d)	Collection Schedule 

	The SIP deadlines for implementing the PM2.5 NAAQS under Subparts 1 and 4 were proposed in proposed PM2.5 SIP Requirements Rule consistent with CAA requirements. Moderate area SIPs will be due within 18 months of the effective date of nonattainment area designation. The proposed rule requests comment on due dates for certain elements of Serious area SIPs; however, under all proposed options BACM/BACT requirements would be due within 18 months of the date an area is reclassified as Serious. Quantitative milestone reports, as required under the CAA, would be due every 3 years. 

      6. Estimating the Burden of the Collection
      
	This section provides information on the hours and costs associated with the information collection for the respondents (the affected state and local air agencies) and EPA (regional and headquarters offices). Hours and costs are presented for the activities associated with each collection item for a nonattainment area (or portion thereof) in a given state, as well as the equivalent annual and present value cost estimates.
   
   6(a)	Estimating Respondent Burden
      
	The estimated respondent burden represents the estimated staff time associated with the activities required to develop the relevant PM2.5 SIP and implement the plan each year. 
      
	The estimated burden in this ICR is incremental to the estimated burden of other EPA environmental reporting obligations. The actual incremental burden is expected to vary across areas for a number of reasons, such as the severity of the nonattainment problem and whether existing federal and state emission reduction programs are projected to bring the area into attainment. 
   	
Burden Estimate for Remaining Nonattainment Areas for 1997 and 2006 PM2.5 NAAQS 
   
   Table 1 provides the list of areas and states still implementing the 1997 and 2006 PM2.5 NAAQS requirements that potentially could be responsible for developing Serious area SIP revisions during the extension of the ICR period. For the purpose of this analysis, it is assumed that one of the original 39 nonattainment areas for the 1997 PM2.5 standard (San Joaquin Valley, CA) will still need to develop a Serious area plan during the ICR period. The estimated burden hours for development of the remaining Serious area SIP is 18,000 hours.  The presumed allocation of total incremental burden across the three years is 50% in year 1, 25% in year 2, and 25% in year 3. 
   
   Of the 32 areas designated as nonattainment for the 2006 PM2.5 standard, Table 1 identifies six areas that potentially could be reclassified from Moderate to Serious during the extension of the ICR period, and that could have a Serious area SIP (or portions thereof) due within 18 months (also within the period for this ICR). For the purposes of this analysis, the estimated burden for development of the SIP revisions to address the Serious area requirements is 18,000 hours. Using the information in Table 1, Table 2 below provides a 3-year breakdown of expected burden hours by state and by year.

6(b)	Estimating Respondent Cost
      
	Labor costs are estimated for state air agencies using the total of projected additional hours for the areas. These estimates do not reflect staff experience and economies of scale. The hourly rates are the result of estimated direct and indirect cost per employee.  The main source of the information is http://www.opm.gov/oca/payrates/index.htm
      
	The estimated weighted direct salary cost per employee is $35.88 per hour.  This results from a summation of the professional, managerial, and support staff components. 
      
      * Hourly equivalent 2012 Salary of Permanent Professional Staff at GS 11, Step 3 is $33.34. This is the average of hourly equivalent rates for the San Francisco, CA and Washington, D.C. areas.
      * To account for permanent managerial staff, 1/11 or 9% of the hourly rate for GS 13, Step 3 is added to the professional staff hourly rates. The average hourly equivalent rate for GS-13 using rates for San Francisco, CA and Washington, D.C. is $47.51. Nine percent of that is $4.32.
      * To account for permanent support staff at GS-6, Step 6, 1/8 or 16% of the hourly rate is added to the professional staff hourly rates.  The average hourly equivalent rate for GS-6, Step 6 using rates for San Francisco, CA and Washington, D.C. is $22.17. Sixteen percent of that is $3.55. 
         
The estimated hourly indirect cost per employee is $23.90. This amount is the sum of the following:

   * Benefits at 16% of the weighted direct hourly equivalent salary cost per employee, or $6.59.
   * Sick and annual leave at 10% of the weighted direct hourly equivalent salary cost per employee, or $4.12.
   * General overhead at 32% of the weighed direct hourly equivalent salary cost per employee, or $13.18.
   	
   The estimated total weighted direct and indirect hourly equivalent salary cost per employee is $65.10. The ICR cost estimates are in 2012 dollars. Federal hourly pay rates did not change between 2010 and 2012. The estimated total incremental respondent burden for the state respondents to meet the new 2012 PM2.5  SIP requirements and complete the remaining 1997 and 2006 SIP requirements is provided in Table 5.

                                    126,000

        
6(c)	Estimating Agency Burden and Cost
      
   The estimated Agency burden is derived from the same estimates used for estimating respondent costs in section 6(b). Draft estimates were developed by the headquarters staff with review by regional office staff and subsequent refinement of the Agency burden and cost estimates.
      
   The respondent burden was summed by the EPA regional offices and a percentage was applied to the yearly burden estimate to reflect the actions taken on the part of the regional offices. Once yearly burdens were estimated for the Agency's Regional Offices, a percentage of those amounts are specified to derive estimates for the Agency's Headquarters Office Burdens.
      
      Agency Regional Office Burden. Table 4 includes estimates of total incremental Agency Regional Office burden. The summary of total incremental respondent burden comes from Tables 1. The Agency Regional Office burden is presumed to be 10% of the estimated total incremental burden for respondent by the EPA Regional Office. The total incremental burden allocation for the Agency Regional Offices is 50% in year 1, 25% in year 2, and 25% in year 3.

      Agency Headquarters Burden.  Table 4 also summarizes total incremental Agency headquarters burden.  The Regional Office burden estimates for years 1, 2, and 3 are multiplied by 10% to arrive at an estimate for headquarters burden for the same 3 years.    
      
      Total Incremental Burden for the Agency. The regional and headquarters office burden estimate for year 1 for the 1997 and 2006 NAAQS is 8,000 hours.  The estimates for years 2 and 3 are 4,000 hours each year.
      
      Total Cost for the Agency. Using the weighted direct and indirect salary equivalent hour rate derived in section 6(b), the total incremental burden hours are multiplied by that rate.  The result is the total cost estimate for the Agency provided in Table 4.

      *The estimates are in current year (2012) dollars.  Costs for years 2 and 3 are calculated using the equation Present Value = Future Value/ (1 + interest rate)t ,where "t" is the number of years hence (i.e., 0 for year 1, 1 for year 2, 2 for year 3).  The adjusted values for years 1, 2, and 3 are then summed.
      

6(e)	Reason for Change in Burden

   We are requesting an decrease in burden to 126,000 hours from the 175,400.  The 126,000 hours is an extension to implement the remaining requirements for the 1997 PM2.5  and 2006 PM2.5  NAAQS.  This burden estimate is lower than the estimate for the previous PM2.5 Implementation ICR renewal primarily because the extension estimates the burden for the 6 areas remaining in nonattainment for the 2006 PM2.5 NAAQS as compared to 31 nonattainment areas initially designated for that NAAQS. In addition, one of the six areas (San Joaquin Valley, CA) remains nonattainment for the 1997 PM2.5 NAAQS.  The estimates have been calculated using 2012 dollars and some assumptions regarding overhead, O&M costs, and capital costs have been adjusted to meet current guidelines and common procedures for preparing ICRs.

6(f)	Burden Statement

      The annual public reporting and recordkeeping burden for this collection of information for the 1997 and 2006 NAAQS is estimated to average 6,000 hours, which is the 42,000 hours average yearly burden for the state air agencies identified in Table 1, and dividing by 7, the number of affected state responses.	

      Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, disclose, or provide information, or for a Federal agency other than the EPA, to do so.  This estimate includes the time and burden needed to conduct the tasks associated with each state submitting the PM2.5 SIP required for each PM2.5 nonattainment area. The PM2.5 SIPs due during this ICR extension period will need to include several elements, including the attainment demonstration, RFP plan, RACT and RACM. In meeting these milestones, such incremental efforts may include reviewing instructions as well as verifying, processing, maintaining, and disclosing information. Such efforts may require incremental development, acquisition, installation, and/or utilization of technological systems for several purposes. These purposes include collecting, verifying, validating, processing, maintaining and disclosing information associated with the each milestone. The incremental efforts may result from adjusting the ways to comply with the previously applicable instructions associated with other NAAQS such as 8-hr ozone and PM10. Consequently, in meeting the milestones, there could be some incremental burden associated with learning/training, searching data sources, and transmitting the deliverables.

   An Agency may not conduct or sponsor, and a person is not required to respond to a collection of information, unless it displays a currently valid OMB control number. The OMB control numbers for the EPA's regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.  When this ICR is approved by OMB, the Agency will publish a technical amendment to 40 CFR part 9 in the Federal Register to display the OMB control number for the approved information collection requirements contained in the final implementation rule. However, as was stated in the April 2007 Federal Register Notice for the PM2.5 Implementation Rule, ".. the failure to have an approved ICR for this rule does not affect the statutory obligation for the state air agencies to submit SIPs as required under part D of the CAA."

   The Agency established a docket for the PM2.5 NAAQS State Implementation Requirements Rule under Docket ID No.OAR-2007-0265.
