## 1 INTRODUCTION The Cincinnati Interstate area is designated as a Basic Ozone Nonattainment Area for the 8-hour National Ambient Air Quality Standard (NAAQS) of 0.08 parts per million (ppm) for ozone. This document is intended to support Kentucky ’s request that the Kentucky portions of the Cincinnati-Hamilton area be redesi gnated from nonattainment to attainment for the 8-hour ozone standard. In addition, the States of Ohio and Indiana also intend to submit requests for their respective portions of the Cincinnati-Hamilton area. Copies of Ohio and Indiana’s submittals can be found in Appendices G and H, respectively. In accordance with section 110(k) of the Cl ean Air Act Amendments of 1990, Kentucky’s request to amend the State Implementation Plan (S IP) is based on the most recent three years of monitoring data showing no additional violationsof the 8-hour ozone standard for the 2007-2009 time period, and a calculated ozone design value for 2007-2009 data that is attaining the NAAQS. Permanent and enforceable reductions inozone precursor emissions have occurred and emission projections demonstrate that the 2008 attainment year emission levels in this area will not be exceeded during the next 12 years. This redesignation request was prepared in accordance with the U.S. EPA memorandum from John Calcagni, June 23, 1992, “Subject: Processing of SIP Submittals,” and U.S. EPA Memorandum from John Calcagni, September 4, 1992, “Subject: Procedures for Processing Requests to Redesignate Areas to Attainment,”and U.S. EPA Memorandum from Michael H. Shapiro, September 17, 1993, “SIP Requirements for Areas Submitting Requests for Redesignation to Attainment of the Ozone NAAQS ...” ( Appendix A ).

## 2 BACKGROUND The Clean Air Act Amendments of 1990 (CAA) es tablishes a process for air quality management through the NAAQS. Area designations are required after promul gation of a new or revised NAAQS. On July 18, 1997, U.S. EPA promulgated a revised ozone standard of 0.08 ppm, measured over an 8-hour period. The 8-hour standard is more protective of public health and more stringent than the previous 1-hour standard of 0.12 ppm. The NAAQS rule was challenged by numerous litigants and in May 1999, the U.S. C ourt of Appeals for the D.C. Circuit issued a decision remanding, but not vacating, the 8-hour standard. Among other things, the Court recognized that U.S. EPA is required to desi gnate areas for any new or revised NAAQS in accordance with the CAA. In February 2001, the U.S. Supreme Court upheldU.S. EPA authority to set the NAAQS and remanded the case back to the D.C. Circuit for di sposition of issues the D.C. Circuit did not address in its initial decisi on. The Supreme Court also remanded the 8-hour implementation strategy to U.S. EPA. In March 2002, the D.C. Circuit rejected all remaining challenges to the 8- hour ozone standard. The process for designations following promulgation of a NAAQS is contained in section 107(d)(1) of the CAA. The Tran sportation Equity Act for the 21 st 

## Century (TEA-21) extended by 1 year the time for U.S. EPA to designate areas for the 8-hour NAAQS. Thus, U.S. EPA was required to designate areas for the revised 8-hour ozone standard by July 2000. However, U.S. EPA’s appropriations bill in 2000 re stricted the agency’s authorityto spend money or designate

## 3 areas until June 2001 or the date of the Supreme Court ruling on the standard, whichever came first. As noted earlier, the Supreme Court decision was issued in February 2001. In accordance with Secti on 107(d)(1) of the CAAA, Federal Register notice (69 FR 23858) published on April 30, 2004, designated the Cincinnati-Hamilton area to be basic nonattainment for the 8-hour ozone NAAQS, effective June 15, 2004 ( Appendix B ). IMPROVEMENT IN AIR QUALITY The 8-hour ozone nonattainment designation was ba sed on air quality data collected from 2001 through 2003 that exceeded the specified NAAQS level of 0.08 ppm. In 2009 the ambient ozone data for Boone, Campbell and Kenton Counties inthe Kentucky portion of the nonattainment area; the nonattainment portion of Butler, Clermont, Clinton, Hamilton and Warren counties in Ohio; and a portion of Dearborn C ounty, Indiana indicated no further exceedances of the 8-hour standard and resulted in a decline in the design value for the most recent three-year period (2007- 2009). The AQS ambient data report is included in Appendix C . Table 1 is a summary of the number of days annually in which the 8-hour NAAQS for ozone 0.08 ppm was exceeded in Boone, Campbell and Kenton Counties, Kentucky; Butler, Clermont, Clinton, Hamilton and Warren counties in Ohio; and a portion of Dearborn County, Indiana. The overall trend is downward in numbers of exceedances that occur annually. A map indicating the location of the eleven ozone monitors in the Cincinnati-Hamilton 8-hournonattainment area is included in Appendix C . Dearborn County, Indiana does not have a monitoring station.

## 5 The data collected by Kentucky was quality a ssured in accordance with 40 CFR 58 and was recorded in the U.S. EPA Air Quality System (AQS ) and is therefore available to the public. The monitoring network will continue to remain operational in accordance to 40 CFR 58, with no monitoring reductions. For this SIP revision, Kentucky first had to develop a Baseline Emissions Inventory for this newly designated nonattainment area . The year 2008 was chosen as the base year for developing a comprehensive ozone precursor emissions inventory for which projecte d emissions could be developed for 2011, 2015, 2018 and 2020. The 2008 data was selected as the attainment year because this is the most current inventory data available for all jurisdictions in the area. Documentation for this inventory is included in Appendix D . The three-year period (2007-2009) brings the design value into attainment for each county, with a calculated value at each monitor well below the 0.08 ppm NAAQS. The Air Quality System (AQS) ambient data for ozone is included in Appendix C. PERMANENT AND ENFORCEABLE EMISSION REDUCTIONS The improvement in air quality in the Cincinnati-Hamilton area, as verified by the lack of exceedances of the 8-hour ozone standard, is due to the implementation of permanent and enforceable emission reductions. General meteorological information regarding temperatures and rainfall for years 2007 through 2009 are included in Appendix C. On a monthly observational basis for the ozone monitoring seas on March-October, it was shown that 2008 was wetter than normal, while 2007 and 2009 were both dryer than normal. This information was provided by the University of Kentucky Agri cultural Weather Center at Covington.

## 6 Emission reductions (in tons per day, or tpd) described below are from various programs and initiatives. The following categories of sources have shown or are expected to show emission reductions in volatile organic compounds (VOCs) and oxides of nitrogen (NOx) emissions due to regulatory measures implemented, both by the U.S. EPA and Kentucky. CONTROLS APPLIED Several control measures already in place or being implemented over the next few years will reduce stationary point, highway mobile, and nonroad mobile sources emissions. The Federal and State control measures were modeled for all of the future years and are discussed in the sections below. F EDERAL

## On February 10, 2000, U.S. EPA finalized a federal rule (65 FR 6698) tosignificantly reduce emissions from cars and light trucks, including sport utility vehicles (SUVs). Under this rule, automakers are required to sell cleaner cars, and refineries are required to make cleaner, lower sulfur gasoline. The federal rules will bephased in between 2004 and 2009. U.S. EPA has estimated that NO x

## emission reductions will be approximately 77% for passenger cars, 86% for smaller SUVs, light trucks, and minivans; and 65% to 95% percent reductions for larger SUVs, vans, and heavier trucks. Emission reductions of VOC will be approximately 12% for passenger cars; 18% for smaller SUVs, light trucks, and minivans; and 15% for larger SUVs, vans, and heavier trucks . The Tier 2 rule also reduced the sulfur content of gasoline to30 ppm starting in January of 2006. Most gasoline so ld in Kentucky prior to January2006 had a sulfur content of

## 7 approximately 300 ppm. Sulfur occurs naturally ingasoline, but interfereswith the operation of catalytic converters on vehicles resulting in higher NOx emissions. Lower-sulfur gasoline is necessary to achieve the Tier 2 vehicle emission standards. H

## New U.S. EPA standards promulgated October 6, 2000, (65 FR 59896) to reduce NOx and VOC emissions from heavy-duty gasoline and diesel highw ay vehicles began to take effect in 2004. A second phase of standards and testing proc edures, which began in 2007, began reducing particulate matter from heavy-duty highway engines, and reduceshighway diesel fuel sulfur content to 15 ppm since the sulfur damages emission control devices. The total program is expected to achieve a 90% reduction in particulate matter (PM) emissions and a 95% reduction in NOx emissions for these new engines using low sulfur diesel , compared to existing engines using higher-content sulfur diesel.

## On May 11, 2004, the U.S. EPA promulgated new rules (69 FR 26222) for large nonroad diesel engines, such as those used inconstruction, agricultural, and industrial equipment, to be phased in between 2008 and 2014. The nonroad diesel rules also reduce the allowable sulfur in nonroad diesel fuel by over 99%. Nonroad diesel fuel currently averages about 3,400 ppm sulfur. The rule limits nonroad diesel sulfur content to500 ppm in 2006 and 15 ppm in 2010. The combined engine and fuel rules would reduce NOx and PM emissions from large nonroad diesel engines by over 90%, compared to current nonroad engi nes using higher-content sulfur diesel.

## On November 8, 2002, the U.S. EPA promulgate d new rules (67 FR 68 242) that regulate NOx, hydrocarbons (HC) and carbon monoxide (CO) for groups of previously unregulated nonroad engines. The new standard applies to all new engines sold in the United States and imported after these standards began and applies to larg e spark-ignition engines (forklifts and airport ground service equipment), recreational vehicles (off-highway motorcycles and all-terrainvehicles), and recreational marinediesel engines. The regulati on varies based upon the type of engine or vehicle. The large spark-ignition engines co ntribute to ozone formation and ambient CO and PM levels in urban areas. Tier 1 of this standard was impl emented in 2004 while Tier 2 began in 2007. Like the large spark-ignition, recreational vehicles contribute to ozoneformation and ambient CO and PM levels. For the off-highway motorcycles and all-terrain-vehicles, model year 2006, the new exhaust emissions standard was phased-in by 50% and for model years 2007 and later at 100%. Recreational marine diesel engines over 37 kilowattsare used in yachts, cruisers, and other types of pleasure craft. Recreational marine engines contribute to ozone formation and PM levels, especially in marinas. Depending on the size of the engine, the standard began to be phased-in during 2006. When all of the nonroad spark-ignition engines and recreational engines standards are fully implemented, an overall 72% reduction in HC, 80% reduction in NOx, and 56% reduction in CO emissions are expected by 2020. These controls will help reduce ambient concentrations of ozone, CO, and fine PM.

## On October 27, 1998, the U.S. EPA made a finding of significant contribution of NOx emissions from certain states and published a rule that set ozone season NOx budgets for the purpose of reducing regional transport of ozone(63 FR 57356). This rule, referred to as the NOx SIP Call, required ozone season controls to be put on utility and very large industrial boilers , as well as internal combustion engines in 22 states in the Eastern United States. This resulted in a NOx emissions budget for each state and the states were required to devel op rules to meet their budget. A trading program of NOx emissions was es tablished, allowing sources to buy credits to meet their NOx budget as opposed to actually installing controls. The emi ssion budgets were to be met by May of 2004. Even with the trading program, the amount of ozone season NOx emissions have decreased signi ficantly in and around Kentucky. MACT Controls Industrial Boiler/Process Heater/RICE MACTs . The USEPA issued final rules to substantially reduce emissions of toxic air pollutants from industrial, commercial and institutional boilers, process heaters and from stationary reciprocating internal combustion engines (RICE). These rules reduce emissions of a number of toxic air pollutants, including hydrogen chloride, manganese, lead, arsenic and mercury by 2009. This rule also reduces emi ssions of SO2 and PM in conjunction with the toxic air pollutant reductions. The applied Maximum Achievable Control Technology (MACT) control effici encies were 4 percent for SO 2 and 40 percent for PM10 and PM2.5. The USEPA’s industrial boiler MACT rule s were vacated on June 8, 2007. The VISTAS states decided to leave these controls in the modeling since it is believed that by 2018 the

The projection inventories do notinclude the NOx co-benefit effects of the MACT regulations for Gas Turbines or stationary Reciprocating Internal Combustion Engines, which the USEPA estimates to be small compared to the overall inventory. VOC 2-, 4-, 7-, and 10-year MACT Standards . Various point source MACTs and associated emission reductions were implemented. Reductions occurring before 2002 were assumed to be accounted for in the base year inventory. S TATE

## In response to the U.S. EPA’s CAIR rule, Kentucky developed regulations 401 KAR 51:210, 401 KAR 51:220, and 401 KAR 51:230, which became effective February 2, 2007. Under the rules, Kentucky has caps as follows: • Annual NOx: 83,205 tons for 2009-2014 and 69,337 tons for 2015 and each year thereafter; • Ozone season NOx: 36,109 tons for 2009-2014 and

## 12 30,651 tons for 2015 and each year thereafter; • Annual SO 2 

## : 188,773 tons for 2010-2014 and 132,141 tons for 2015 and each year thereafter. The State’s NOx allocations have been distributed based on allocation methodologies in regulations 401 KAR 51:210 and 401 KAR 51:220. The U.S. EPA will determine the SO 2 

## allocations, which are based on the acid rain program. This rule does not preclude Kentucky from adopting additional emission reduction requirements for covered sources if necessary to attain or maintain an ambient air quality standa rd. Reductions due to this regulation and CAIR were not included in the inventory and its projections. MAINTENANCE PLAN Section 107(d)(3)(e) of the CAA mandates that for anarea to be redesignated to attainment, the U.S. EPA must approve a maintenance plan that meets the requirements of Section 175A of the CAA. The maintenance plan must constitute a SIP revision and provide for maintenance of the air quality in an affected area for at least 10years after redesignation. Kentucky has chosen to project emissions through the year 2020. The maintenance plan includes an emissions inventory for the attainment year (2008), projected inventories through a 12 year period (2020), a commitment to maintain the existing monitoring system, and contingency measures that will becomeeffective should the area fail to continue to maintain the 8-hour ozone standard.

## 13 E MISSION 

## PROJECTION 

## M ETHODOLOGY 

## One of the planning elements listed in the memorandum dated September 4, 1992, ( Appendix A ) required for attainment redesignation purposes is developing a proj ection inventory that indicates the area will remain in attainment and which includes emission projections for at least ten years after U.S. EPA’s official redesignation approval. Kentucky’s projection inventory through the year 2020, and the methodology for performing that inventory, is located in Appendix F. The base year for Boone, Campbell, and Kenton Counties is 2008. Kentucky used actual 2008 emissions for point sources. Do cumentation of the point source emissionsinventory is in Appendix D . Economic numbers provided by the U.S. Department of Commerce Bureau of Economic Analysis (BEA) were used to project from the 2008 actual inventory for point sources to 2015 and 2020. Emissions for the base year, the attainment year , and all interim years for highway mobile were developed by Ohio-Kentucky-Indiana Regional Council of Governments (OKI) using U.S. EPA’s MOBILE 6.2 mobile emissions model. The technical support document is provided in Appendix E . The base year of 2008 for Kentucky area and nonroad sources, as well as 2011, 2015, 2018 and 2020 were projected by the Lake Michigan Air Directors Consortium (LADCO) using their 2005 Base Year Inventory methodology as provided in Appendix F. The 2008 Kentucky counties’ base year inventory is provided in Appendix D . The area and nonroad projected emission inventories for 2011, 2015, 2018 and 2020 are included Appendix F.

## 14 A maintenance demonstration requires comparison of the projectedemissions inventory with the baseline inventory. If the projected emissions remain at or below the baseline emissions, there is a demonstration of maintenance. If, however, the projected emissions are above the baseline, then additional measures are required to ensure the projected emissions will remain at or below the baseline emissions. Tables detailing the category proj ection inventories for VOC and NO x

## emissions for the attainment year 2008, and y ears 2011, 2015, 2018 and 2020 are included for Boone, Campbell and Kenton Counties in Appendix F. Biogenic emissions have been excluded from these projection tables. Based on information received from U.S. EPA, biogenic emissions are expected to remain stable throughout the projection period. Tables 3 through 8 detail the projection of emissions through 2020. Boone, Campbell and Kenton Counties’ projected 2020 total emissions for both VOC and NOx are below the 2008 total emissions, thus demonstrating continued maintenance of the 8- hour ozone standard. Emissions for 2005 are provided to be consistent with Ohio and Indiana’s submittals to indicate the change in emissions up to the attainment y ear. Even though the VOC emissions increase in Boone County from 2005 to 2008, the overall VOC emissions decrease.

## 17 The emissions inventory is broken down into fourcomponents: point, area, highway mobile, and non-highway mobile sources. Using 2008 as the attainment year, the subsequent years were chosen at appropriate interval s and project maintenance for atleast a 10-year period pending approval of the revision of the SIP. The following sections describe of how growth factors for each emission category were obtained and used. Documentation showing how emissions were grown is included in Appendix F. P OINT 

## S OURCES 

## For this inventory purpose, point sources are define d as stationary sources that emit greater than 10 tons per year (tpy) of VOCs, or 100 tpy of NOx or CO. The source emissions are calculated from data collected annually from the sources. This information is stored in an existing Kentucky Emissions Inventory System database and that informati on has been uploaded into the U.S. EPA National EmissionsInventory (NEI) system. For point source emission projections, a comparison was made between employment projections and earnings projections using BEA data. The point source data provided SIC codes, used to determine a short title description that matches the correspondi ng description found in the BEA data. The application of these growth factors for each projection was then used for point sources. Appendix F provides information on how growth was projected for point sources. Each county total is listed in the summary table under point sources.

## To calculate emissions from mobile sources, the division obtained mobile source emission projections from OKI in Cincinnati, Ohio. This organization is the metropolitan planning organization for the Greater Cincinnati area. These data and documentation on how these projections were perf ormed can be found in Appendix E, including input and output files for those projections. A REA SOURCES

## As previously stated above, the emissions and projections for area and nonhighway mobile sources were provided by LADC O. A more thorough discussi on and documentation of these emissions and projections is provided in Appendix F. Safety Margin The transportation conformity regulation, 40 C.F.R. Part 93, Subpart A, Conformity to State or Federal Implementation Plans of Transportation Plans, Program s, and Projects Developed, Funded or Approved Under Title 23 U. S.C. or the Federal Transit Laws, requires that mobile source emissions submitted or approved to a state’ s SIP be used in determining conformity of transportation plans for the area. This regulation also allows the addition of a safety margin to the mobile emissions budgets. Per 40 CFR 93.101, the safety margin is defined as “the amount by which the total projected emission from all sources of a given pollutant are less than the total emissions that would satisfy the applicable requirement for reasonable further progress, attainment or maintenance.” Tables 9 through 14 show a summary of the 2008 attainment year, and the 2020 projected out year emissions, and the corresponding safety margins.

## emissions in the nonattainment area are projected to decrease by 46.95 tons/day. Decreases from U.S. EPA rules covering Tier 2 Motor Vehicle Emissions Standards and Gasoline Sulfur Control Requirements, Highway Heavy-Duty Engine Rule, and the Non-Road Diesel Engine Rule are factored into the changes. PLAN TO MAINTAIN AIR QUALITY The Commonwealth of Kentucky and the U.S. EPA have instituted programs that will remain enforceable and are hereby submitted as a plan tomaintain air quality which meets the NAAQS for the 8-hour ozone standard. Sources are prohibited from reducing emission controls following the redesignation of the area. • All new major VOC sources locating inKentucky are subject to RACT; • All major modifications to existing ma jor VOC sources are subject to RACT requirements; • Implementation of a program to enhance in spection of stationarysources to ensure emission control equipment is functioning properly; • Requirement for Stage II Vapor Recovery; • Federal Motor Vehicle Control Standards apply in Kentucky; • Reformulated Gasoline • Federal controls on the VOC content for Architectural & Maintenance Paints, Auto Body Shops, and Consumer Products • Open burning ban during summer ozone season for three county area; • Prevention of Significant Deterioration requirements. In addition to these measures, further reductionswill be achieved throughout the implementation of new federal regulations to further control the emission of Hazardous Air Pollutants that are VOCs and the emission control programs being imposed as a result of enforcement agreements with some sources in the area. The reductions cannot be quantified at this time, but will be reflected in future triennial assessments.

## 26 EXISTING MONITORING NETWORK In addition to the maintenance plan discusse d above, the existing ozone monitoring network located within the Kentucky counties of the Cincinnati-Hamilton Basi c Ozone Nonattainment area has been approved by the U.S. EPA. The monitoring network will continue to remain operational in accordance to 40 CFR 58, with no reductions. CONTINGENCY MEASURES Future reviews of actual emissions for this redesignated area will be performed using the latest emission factors, models, and methodologies. For these periodic inventories, Kentucky will review the assumptions made for the purpose of the maintenance demonstration concerning projected growth of activity levels. If any of these assumptions appear to have changed substantially, Kentucky will re-project emissions. In the event that a measured value of the fourth highest maximum is 0.085 ppm or greater in any portion of the maintenance area in a single ozoneseason, or if periodic emission inventory updates reveal excessive or unanticipated growth greater than 10% in ozone precursor emissions, the state will evaluate existing control measures to see if any further emission reduction measures should be implemented at that time. In the event of a monitored violation of the 8-hour ozone NAAQS standard in the CincinnatiHamilton maintenance area, the Commonwealth commits to adopt, within nine months, one or more of the following contingency measures to re -attain the standard. All regulatory programs will be implemented within 18 months af ter the triggering monitored violation. • Implementation of a program to require additional emission reductions on stationary sources;

## 27 • Implementation of fuel programs, including incentives for alternative fuels; • Restriction of certain roads or lanes to, or construction of such roads or lanes for use by, passenger buses or high-occupancy vehicles; • Trip-reduction ordinances; • Employer-based transportation management plans, including incentives; • Programs to limit or restrict vehicle use in downtown areas, or other areas of emission concentration, particularly during periods of peak use; • Programs for new construction and major recons tructions of paths or tracks for use by pedestrians or by non-motorized vehicles when economically feasible and in the public interest. Kentucky also reserves the right to implement other contingency measures if new control programs should be developed and deemedmore advantageous for the area. Section 175A(b) of the CAA requires that eight years after formal redesignation, the state continues to provide for maintenance of the standard by submitting another maintenance plan that covers an additional 10 years. If this requirement remains applicable for this area, Kentucky commits to submit to U.S. EPA a plan for future maintenance of the standard in Boone, Campbell and Kenton Counties as required. PUBLIC PARTICIPATION Kentucky held a public hearing to receive comments on this proposed redesignation request on January 5, 2010 at the offices of the Northern Kentucky Area De velopment District. A copy of the public hearing notice and a copy of the advertis ements are included in Appendix I. A copy of the Energy and Environment Cabinet’s response to comments received during that public review period is included as Appendix J.

## MEMORANDUM

SUBJECT: Processing of State Implementation Plan (SIP)

Submittals FROM: John Calcagni, Director

Air Quality Management Division, OAQPS (MD-15) TO: Director, Air, Pesticides and Toxics

Management Division, Regions I and IV Director, Air and Waste Management Division, Region II Director, Air, Radiation, and Toxics Division, Region III Director, Air and Radiation Division, Region V Director, Air, Pesticides, and Toxics Division, Region VI Director, Air and Toxics Division, Regions VII, VIII, IX, and X This memorandum provides guidance concerning the processing of SIP submittals. In general, there are three situations that can occur related to each required submittal: the State may fail to submit the required plan, the State may make a submittal that is not complete, or the State may make a complete submittal. Once a State submits a SIP and the Environmental Protection Agency (EPA) has determined that the submittal is complete, EPA must either approve or disapprove the submittal within a specified time period. However, if the State fails to make a required submittal or makes a submittal that is determined to be incomplete, the sanctions and Federal implementation plan (FIP) provisions of sections 179 and 110(c), respectively, will be triggered. In addition, disapproval of a submittal also triggers the sanctions and FIP provisions. These provisions are discussed in further detail in this memorandum. There are, however, three alternatives to full approval or full disapproval of a complete SIP submittal: partial approval,

## limited approval, and conditional approval. Each of these is

discussed in more detail below along with some guidance as to when each might be used. In addition, Attachment 1 to this memorandum contains several examples of how these may be used. Attachment 2 to this memorandum is a table that summarizes the requirements discussed below. Partial Approval/Disapproval Section 110(k)(3) of the amended Clean Air Act (Act) addresses the situation in which an entire submittal, or a separable portion of a submittal, meets all applicable requirements of the Act. Where the entire submittal meets all the requirements of the Act, EPA will fully approve the entire submittal. In the case where a separable portion of the submittal meets all of the applicable requirements, partial approval may be used to approve that part of the submittal and disapprove the remainder. It is important that the two parts of the submittal be separable. By separable, EPA means that the action it anticipates taking will not result in the approved rule(s) being more stringent than the State anticipated. See Bethlehem Steel Corp. v. Gorsuch , 742 F. 2d 1028 (7th Cir. 1984); Indiana and Michigan Elec. Co. v. U.S. E.P.A. , 733 F. 2d 489 (7th Cir. 1984). For example, EPA cannot approve part of a submittal that specifies control measures and disapprove the part that specifies the test methods associated with those control measures. The EPA has frequently taken a partial approval approach in the past to process groups of rules that are submitted together. The EPA can approve some of the rules and disapprove the rest as long as the rules that are disapproved do not affect those that are approved. The disapproval of any part of a required SIP submittal starts the clocks discussed above for sanctions and FIP's. Limited Approval/Disapproval In some cases, a submittal may contain certain provisions that meet the applicable requirements of the Act along with other provisions that do not meet the requirements, and the provisions are not separable. Although the submittal may not meet all of the applicable requirements, EPA may want to consider whether the submittal as a whole has a strengthening effect on the SIP. If that is the case, limited approval may be used to approve a rule that strengthens the existing SIP as representing an improvement over what is currently in the SIP and as meeting some of the applicable requirements of the Act. The Act does not expressly provide for limited approvals.

The March 22, 1991 memorandum from John Calcagni 1 

## discussed the potential impact of Abramowitz v. U.S. E.P.A. , 832, F. 2d 1071 (9th Cir. 1988), on EPA's decision to split the approval and disapproval portions of a limited approval. After reevaluating that case, we believe it may have a narrower impact than initially described and, therefore, generally would not impact the timing of limited approval/disapproval actions. Rather, EPA is using its "gap-filling" authority under section 301(a) of the Act in conjunction with the section 110(k)(3) approval provision to interpret the Act to provide for this type of approval action. Through a limited approval, EPA would concurrently, or within a reasonable time thereafter, disapprove the rule, under the relevant provision(s) of Part D, for not meeting all of the applicable requirements of the Act. As with the limited approval action the limited disapproval is a rulemaking action, and it is subject to notice and comment. Under section 110(k), EPA must take final rulemaking action on SIP submittals within 12 months of the date EPA determines the submittal is complete or the submittal is automatically deemed to be complete if EPA fails to make a completeness determination. As a general matter, although the statute directs EPA to act within that timeframe, EPA's failure to finalize the disapproval portion of the action within that 12-month timeframe will not affect the validity of any prior or subsequent limited approval or limited disapproval. The 1 

## EPA's failure to take action prior to the expiration of the 12- month period could, however, subject EPA to a lawsuit to compel such an action. A key distinction between the limited approval and a partial approval is that under a limited approval EPA's approval action goes to the entire rule. In other words, although portions of a rule prevent EPA from finding that the rule meets a certain requirement of the Act, EPA believes that the rule, as a whole, strengthens the SIP. Therefore, EPA approves the entire rule-- even those portions that prohibit full approval. Likewise, when EPA issues the limited disapproval, the disapproval applies to the entire rule as failing to meet a specific requirement of the Act. The rule remains a part of the SIP, however, under the limited disapproval, because the rule strengthens the SIP. The disapproval only applies to whether the submittal meets a specific requirement of the Act and does not affect incorporation of the rule into the approved, federally enforceable SIP.

## 4

The primary advantage to using the limited approval approach is to make the State submittal federally enforceable and to increase the SIP's potential to achieve additional reductions. Therefore, limited approval should not be used to approve any rule that is unenforceable for all situations--for example, a rule that lacks a test method. These rules and any other rules that do not have an overall strengthening effect on the SIP should be disapproved. Limited approval can be used, however, where the rule is unenforceable for some limited number of situations but is enforceable for the majority of situations, if the rule, as a whole, strengthens the SIP. The disapproval coinciding with (or following) the limited approval also starts the sanctions and FIP clocks discussed above. With the limited approval EPA may or may not have a commitment from the State to correct the deficiency. The EPA may choose to use the limited approval approach (instead of conditional approval) in the case where the State has submitted a commitment as part of a rule but EPA has reason to believe that the State will not be able to meet the commitment (as discussed below). Where a limited approval/disapproval approach is taken, the notice of proposed rulemaking (NPR) should clearly identify which requirements have not been met and what action would be required on the part of the State to meet those requirements. Conditional Approval Under section 110(k)(4) of the Act EPA may conditionally approve a plan based on a commitment from the State to adopt specific enforceable measures within 1 year from the date of approval. If the State fails to meet its commitment within the 1-year period, the approval is treated as a disapproval. We expect that conditional approvals will be used only in rare situations that merit special consideration. We will evaluate specific types of SIP submittals [e.g., reasonably available control technology (RACT) catch-ups, particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10) SIP's] to determine whether certain elements of that type of submittal, or that type of submittal as a whole, merit conditional approval. For this reason and to ensure consistency, Regions should not use conditional approvals without input from Headquarters as to whether such an approach is appropriate. Furthermore, as any statutory deadline approaches, we may issue guidance regarding the appropriate use of conditional approval with respect to that specific requirement. Once a determination has been made that a specific type of submittal can be considered for conditional approval, Regions

## 5

Although the commitment must identify the measures to 2 

## be adopted and contain a schedule for adopting such measures, it is not necessary for the commitment itself to be enforceable in a State court. must make a determination of whether an individual State submittal should be conditionally approved. The first consideration should be whether the State has made (or agrees to make) a commitment to adopt specific enforceable measures within 1 year of EPA approval. The commitment must be made in writing
by the party responsible for adopting the specified measures before the plan is conditionally approved, and the commitment must be submitted by the State. 2 

## In addition, to the extent that the commitment materially alters the existing rule (in respects that the public could not reasonably have anticipated would result from the public review of the existing rule), or is a commitment to adopt an entire rule or set of rules, the commitment must be a SIP revision submittal by the State. In many cases, the determination of whether the commitment materially alters the underlying rule may be based on whether a similar issue was raised during the earlier State proceedings on the submitted rule. In general, each commitment will need to be examined to determine whether it materially alters the submitted rule. As with any SIP revision, in order for EPA to accept the commitment as a SIP revision, the State must have provided notice and public hearing on the submitted commitment. However, EPA has the discretion to parallel process commitments and in limited circumstances may propose conditional approval of the commitment and allow the State process to proceed on a parallel track. As a general matter, the greater the extent to which a submittal is lacking in important plan elements, the less appropriate the use of conditional approval may be. It should be noted, however, that there may be circumstances under which EPA would accept a SIP revision consisting of a commitment only (without specifically adopted rules) as a candidate for conditional approval. In such cases, the commitment should also be accompanied by a work plan detailing any specific measures to be adopted, the steps that will be taken to adopt the measures,

## 6

and the schedule for adoption of those measures. As stated earlier, a submittal that consists entirely of a commitment will be considered a SIP revision that is subject to the State process for submitting SIP revisions, e.g., notice and a public hearing. Where the submittal contains specifically adopted rules that need some revisions or corrections to be fully-approvable, the commitment may not need to be as comprehensive. The commitment should, however, be as explicit as possible concerning the measures that will be adopted, the steps that will be taken to adopt the measures, and the schedule for adoption of those measures. Because the conditional approval relies on a commitment from the State, EPA would need some level of confidence that the State would be able to meet such a commitment. In making a determination as to whether a State could reasonably be expected to meet its commitment, EPA would need to consider a number of factors such as:

- the amount of technical work necessary for the measures to be adopted;

- whether adoption of the measures is expected to be controversial;

- the average length of the State adoption process;

- how far along in the process the State is; and

- the State's past track record. It should be noted that these are only some of the factors that should be considered. Each Region, in making a determination regarding the credibility of the State's commitment, may have to look at a number of other factors. The Region should clearly explain, either in the NPR or in a technical support document, the rationale for these determinations. In addition to the determination of whether the State's commitment is credible, the Region must make a determination as to whether it is appropriate to conditionally approve a revision on the merits of that revision. Conditional approval might typically be used in the same types of situations as the limited approval. As with the limited approval, one of the main advantages of the conditional approval approach is to make the State submittal (where the submittal contains control requirements and not just a commitment to adopt enforceable measures) federally enforceable and to increase its potential to achieve additional reductions. Because the conditionally approved submittal will become a part of the SIP, the Region

## 7

It should be noted that this disapproval can be a 3 

## limited approval/disapproval. In some cases, the Regions may want to use such an approach to retain the enforceability of control measures. The NPR should indicate if this approach is planned. To provide for this contingency, in the final

## conditional approval, EPA would need to provide, for example, "If the State fails to make a submittal or makes only an incomplete submittal during the time period for submittal of the rule, EPA will issue a letter to the State which converts the conditional approval to a disapproval." should be certain that the approval of the commitment will not weaken the existing SIP. The Region may also want to consider when the plan (or plan element) that has been submitted was due. The NPR for a conditional approval should clearly identify which requirements are the subject of the commitment and, therefore, have not been met. In addition, both the NPR and the State's commitment should clearly identify what action is required on the part of the State. Unlike the limited approval/disapproval, the conditional approval does not immediately start the sanctions and FIP clocks. These clocks start if and when the approval is converted to a disapproval. There are at least two ways that the conditional approval may be converted to a disapproval. First, if the State fails to 3 

## adopt and submit the specified measures by the end of 1 year (from the final conditional approval), or fails to submit anything at all, EPA will have to issue a finding of disapproval but will not have to propose the disapproval. That is because in the original proposed and final conditional approval, EPA will have provided notice and an opportunity for comment on the fact that EPA would directly make the finding of disapproval (by letter) if the State failed to submit anything. Therefore, at 4 

## the end of 1 year from the conditional approval, the Regional Administrator (RA) will send a letter to the State finding that it had failed to meet its commitment and that the SIP submittal is disapproved. The 18-month clock for sanctions and the 2-year clock for a FIP start as of the date of the letter. Subsequently, a notice to that effect will be published in the Federal Register , and appropriate language will be inserted in the Code of Federal Regulations. Similarly, if EPA receives a submittal addressing the commitment but determines that the submittal is incomplete, the RA will send a letter to the State making such a finding. As with the failure to submit, the sanctions and FIP clocks will begin as of the date of the finding

## 8

Section 110(m) grants EPA broad authority to apply 5 

## either sanction listed in section 179(b) " . . . at any time (or at any time after) a finding . . ." under section 179(a) with respect to any portion of the State, with certain exceptions. This memorandum is intended to address the application of sanctions under section 179. The section 179 sanctions apply only to the area for which a finding has been made.

Although subsections (1)-(4) refer to findings, 6 

## determinations and disapprovals, for simplicity these four actions will be referred to as "findings." letter. Second, where the State does make a complete submittal by the end of the 1-year period, EPA will have to evaluate that submittal to determine if it may be approved and take final action on the submittal within 12 months after the date EPA determines the submittal is complete. If the submittal does not adequately address the deficiencies that were the subject of the conditional approval, and is therefore not approvable, EPA will have to go through notice-and-comment rulemaking to disapprove the submittal. The 18-month clock for sanctions and the 2-year clock for a FIP start as of the date of final disapproval. If EPA determines that the rule is approvable, EPA will propose approval of the rule. In either instance, whether EPA finally approves or disapproves the rule, the conditional approval remains in effect until EPA takes its final action. It should be noted that EPA will conditionally approve a certain rule only once. Subsequent submittals of the same rule that attempt to correct the same specifically identified problems will not be eligible for conditional approval. Sanctions and FIP Requirements Actions that Trigger the Sanctions and FIP Requirements The actions EPA has the authority to take under the sanctions and FIP provisions of the Act correspond to the different steps EPA must follow as it reviews and processes SIP submittals. As discussed previously, the Act in section 179 5 

## requires EPA to impose sanctions based on four types of actions (findings ) provided in section 179(a):

6 

## (1) a finding that a State has failed to submit a SIP, a

## 9

Since EPA does not intend to issue a list of such 7 

## elements per se, to ensure that such findings are consistently applied, findings of failure to submit SIP elements should be decided on a case-by-case basis in conjunction with Headquarters. The basis for the finding should be clear and well-supported.

8 

## Since the deficiency is a failure to implement after a State has submitted a plan and EPA has approved it, it is unnecessary for this finding to trigger a requirement that EPA develop the required rule (i.e., prepare a FIP) and section 110(c)(1) does not require it.

SIP element, or has submitted a SIP or SIP element 7 

## that does not satisfy the completeness criteria; (2) that EPA disapproval of a SIP submission for a nonattainment area based on its failure to meet one or more elements required by the Act; (3) a determination that the State has not made any other submission, has made an inadequate submission (as required by the Act), or that EPA disapproves such a submission; or (4) a finding that a requirement of an approved plan is not being implemented. Under section 110(c)(1), EPA is required to promulgate a FIP based on two types of findings: 8 

## (1) a finding that a State has failed to make a required submittal or that a submittal does not satisfy the minimum completeness criteria established under section 110(k)(1)(A), or (2) the EPA disapproval of a SIP submittal in whole or in part. The Sanctions and FIP Clocks Although EPA may make any of the findings discussed above to trigger the 179(a) sanctions and 110(c)(1) FIP requirements, these findings do not require the immediate imposition of sanctions or promulgation of a FIP. Instead the Act provides a "clock" for sanctions and FIP's. For plan submittals required under Part D or in response to a SIP call, section 179(a) allows

## 10

Where EPA made a finding of failure to submit and 9 

## subsequently finds that the State has made a complete submittal for the plan or plan element that was the subject of the finding, the letter that makes the finding of completeness will notify the State that the sanctions clock is stopped as of the date of that for up to 18 months for the State to correct the deficiency that is the subject of a finding or disapproval before EPA is required to impose sanctions. Section 110(c)(1) provides for up to 2 years for the State to correct the deficiency and for EPA to approve a new submittal before EPA is obligated to promulgate a FIP.The Administrator has delegated the authority to make findings of failure to submit to the RA's. The findings are made via letters from the RA's to State governors or other State officers to whom authority has been delegated. The letter itself triggers the sanctions and FIP clocks. For disapprovals, the Federal Register notice in which EPA takes final action triggers the sanctions and FIP clocks. Findings of nonimplementation have traditionally been processed as rulemaking actions through Headquarters. The sanctions clock will start when EPA makes a finding of nonimplementation in the Federal Register after soliciting comment on the proposal (the FIP clock is not triggered by such a finding). Although the findings of failure to submit and SIP disapproval start both the sanctions and FIP clocks, what is required to stop the clocks differs; therefore, they are discussed separately. Note that in some cases the sanctions clock may be stopped while EPA remains under an obligation to promulgate a FIP. Sanctions Clock Under section 179(a), in order to stop the sanctions clock, the State must correct the "deficiency" prompting the finding. The EPA must apply one of the two sanctions available under section 179(b) within 18 months after the date of the finding and both sanctions at 24 months, unless the deficiency has been corrected. Section 179(a) also requires EPA to apply both sanctions after 18 months if EPA finds a lack of good faith on the part of the State. Attachment 3 provides seven scenarios illustrating how the sanctions clock operates, including examples of what constitutes a deficiency correction (and hence a stopping of the clock). In brief, for purposes of the sanctions clock, findings of failure to submit plans or complete plans are corrected when EPA finds the submittal complete [although the FIP clock is still 9

## 11

letter. The Region should periodically announce any such findings that represent corrections of failure to submit in the Federal Register .

In addition, section 179(a) provides for an air 10 

## pollution grant sanction that applies to grants EPA may award under section 105. However, since it is not a sanction provided under section 179(b), it is not one of the sanctions EPA must impose after the 18-month period. running (see FIP clock discussion)] and disapprovals are corrected when EPA takes final rulemaking action approving the plan. In addition, findings of nonimplementation are corrected when EPA makes a finding in the Federal Register that the State is now implementing that provision. FIP Clock Under the FIP provisions, either a SIP must be approved or a FIP must promulgated within 2 years of one of the two findings discussed above. In other words, EPA must approve the State submittal in order to stop the FIP clock. Where the sanctions and FIP clocks were started by EPA disapproval of a plan, the clocks will run concurrently. In this case, to correct the deficiency for purposes of the sanctions clock, the State must make a submittal which EPA finds approvable. Such a determination is not made until EPA issues a final approval of the plan. Final approval of a plan is also what is needed to stop the FIP clock. Attachment 3 provides seven scenarios of how the FIP clock operates.
Available Sanctions For plan submittals required under Part D or in response to a SIP call, if the State does not correct the specific deficiency within the 18-month period allowed under section 179(a), EPA must apply at least one of the two sanctions available under section 179(b) as described:

10 

## (1) Highway funding sanctions. The EPA may impose a prohibition on the approval by the Secretary of Transportation of certain projects, or the awarding of certain grants.

## 12

(2) Offset sanctions. A ratio of at least 2-to-1 will be required for emissions reductions within the nonattainment area to offset emissions from new or modified major facilities (as required under section 173). Regions should determine which of the sanctions will be applied at the 18- and 24-month milestones on a case-by-case basis. As discussed previously, EPA must apply both sanctions at the 18-month mark if it finds there is a lack of good faith effort. Such a determination should be made on a case-by-case basis in consultation with Headquarters. In addition, once one of the sanctions has been imposed, EPA must impose the second sanctions if the deficiency has not been corrected within 6 months (regardless of the State's efforts). Headquarters will issue a proposal of the sanctions and the Regional Office will issue the final rule imposing sanctions.

## Attachment 1

Example 1 A State submits a SIP revision containing four rules: (1) control requirements for bulk gasoline plants, (2) control requirements for gasoline dispensing facilities (Stage I), (3) leak detection requirements for gasoline tanks trucks, and (4) test methods that apply to these three rules. The EPA review of the rules shows that all of the rules except the Stage I rule meet the applicable requirements of the Act. The Stage I rule fails to require submerged fill loading for all storage tanks. This is inconsistent with EPA's RACT guidance and the State has failed to propose an alternative that it has demonstrated is RACT for the applicable sources. Partial Approval Under the partial approval option, EPA can approve the rules for bulk terminals and tank truck leaks, approve the test methods, and disapprove the Stage I rule. These rules are separable from the Stage I rule. Disapproval of the Stage I rule does not affect the stringency of the other three rules. Therefore, the other three rules may be approved under this provision. However, the submittal as a whole would only be partially approved. Limited Approval of Stage I Rule Under the limited approval approach, EPA could approve the Stage I rule as being an improvement over what is currently in the SIP and, at the same time or within a reasonable time after the approval (but no later than 12 months after the submittal is complete), disapprove the rule because it does not represent RACT. The sanctions and FIP clocks would start upon the final disapproval of the rule. Conditional Approval Alternatively, EPA could conditionally approve the Stage I rule if the State committed to revise the rule, within 1 year of the conditional approval, to require submerged fill loading. If the State then failed to make such a revision, EPA would issue a finding converting the conditional approval to a disapproval. Example 2 If in example 1 the first three rules (containing control requirements) are all approvable but the fourth (containing the test methods) is either deficient or has not been submitted, then the submittal would have to be handled differently. Because a test method is critical in determining the stringency of a control requirement and is needed for the requirements to be enforceable, these rules cannot be considered separable and,

## therefore, partial approval would not be an option. In addition,

because the control requirements will not be enforceable without a test method, it would not be appropriate to use either the limited or conditional approval approach. Example 3 A State submits a SIP revision that contains four PM-10 rules, two for controlling emissions of fugitive dust and two for the control of residential wood combustion. The rules represent reasonable available control measures (RACM) and include (1) paving or stabilizing unpaved roads, (2) developing a traffic reduction plan for unpaved roads, (3) a mandatory episode curtailment program for residential wood combustion, and (4) encouraging changeover to new source performance standards and wood stoves. The third rule is deficient in that it does not provide a communication strategy on which the curtailment program is dependent. Partial Approval The EPA may approve the three rules which satisfy RACM but disapprove the episode curtailment program as failing to meet the RACM requirement. These rules are separable because disapproval of the curtailment program will not have any effect on the stringency or enforceability of the remaining rules. Limited Approval The EPA may approve the episode curtailment plan as strengthening the SIP by providing enforceable measures in a SIP which currently has no curtailment program. At the same time or within a reasonable time after the approval (but no later than 12 months after the submittal is complete), EPA must disapprove the rule as not representing RACM. Final disapproval of the rule would start the sanctions and FIP clocks. Conditional Approval The EPA may conditionally approve the rule if the State submits a commitment to submit a revised rule within 1 year of the approval. If the State then failed to make such a revision, EPA would issue a finding converting the conditional approval to a disapproval.

## Attachment 3: Sanctions and FIP Clocks Scenarios

Scenario 1 : The EPA receives a SIP and finds it incomplete

prior to the statutory due date of the SIP. Although a finding that the State submitted an incomplete SIP is one of the section 179(a) findings, the sanctions and FIP clocks will not begin to run until after a submittal is due. This is because the finding must be based on the failure to submit a complete requiredSIP or SIP element and the submittal is not required until it is due under the statute. If a SIP submitted prior to a due date is still incomplete by the due date, then EPA will notify the State by letter that the plan remains incomplete and that the 18-month sanctions clock and the 2-year FIP clock have started. Scenario 2 : The EPA receives a SIP and finds it incomplete on

or after the statutory due date of the SIP. If EPA receives a SIP and finds it incomplete pursuant to section 110(k) on or after the statutory due date of the SIP, then, as in scenario 1, the State has failed to make a complete submittal under section 179(a). The EPA will notify the State by letter that the plan is incomplete and that the 18-month sanctions clock and the 2-year FIP clock have started. Scenario 3 : The EPA receives no submittal at the due date. If EPA receives no submittal from a State to meet a statutory due date, then it may make a finding of failure to submit under section 179(a)(1), triggering the 18-month sanctions clock and the 2-year FIP clock. Scenario 4 : After the due date, EPA receives a SIP for which

it originally made a finding of failure to submit. Upon receiving the plan, the sanctions clock will continue to run during the completeness review and be stopped if EPA finds the plan complete and continue if EPA finds the plan incomplete. If the 18 months elapse during the time EPA is doing its completeness review, EPA will not impose sanctions unless it determines the plan incomplete. If sanctions have been imposed prior to the State's submittal, the sanctions will remain in place until EPA determines the submittal complete. The FIP clock continues to run while EPA makes its completeness determination. Scenario 5 : The EPA originally makes a finding of failure to

submit, then receives a SIP, finds it complete, but disapproves it in final rulemaking.

## Upon a determination that the SIP is complete, the State

corrects the deficiency that prompted the finding of nonsubmittal and the sanctions clock stops. A new sanctions clock will start upon the final SIP disapproval rulemaking. The new sanctions clock will not stop until EPA has taken final action to approve the revised SIP submittal. Even after the submittal is determined to be complete, EPA remains under obligation to promulgate a FIP. Therefore, the disapproval of the SIP does not start a new FIP clock. Scenario 6 : The EPA originally makes a finding of failure to

submit, then receives a SIP, finds it complete, and approves it in final rulemaking. Upon a determination that the SIP is complete, the State corrects the deficiency prompting the finding of nonsubmittal and the sanctions clock stops. The EPA remains under obligation to promulgate a FIP until EPA takes final rulemaking action to approve the SIP. Scenario 7 : The EPA finds that a State has failed to implement

a SIP or SIP provision. The EPA will make a finding of nonimplementation in the Federal Register after soliciting comment on the proposal. The sanctions clock will start upon EPA taking final action and stop when EPA makes a finding in the Federal Register after noticeand-comment rulemaking that the State has corrected the deficiency that prompted the finding. A finding of nonimplementation does not start a FIP clock.

MEMORANDUM SUBJECT: State Implementation Plan (SIP) Requirements for Areas

Submitting Requests for Redesignation to Attainment of the Ozone and Carbon Monoxide (CO) National Ambient Air Quality Standards (NAAQS) on or after November 15, 1992 FROM: Michael H. Shapiro Acting Assistant Administrator for Air and Radiation (ANR-443) TO: Director, Air, Pesticides and Toxics

Management Division, Regions I and IV Director, Air and Waste Management Division, Region II Director, Air, Radiation and Toxics Division, Region III Director, Air and Radiation Division, Region V Director, Air, Pesticides and Toxics Division, Region VI Director, Air and Toxics Division, Regions VII, VIII, IX, and X I. Purpose The purpose of this memorandum is to address State requests to redesignate from nonattainment to attainment of the ozone and CO NAAQS under section 107. Specifically at issue are requests submitted on or after November 15, 1992 where outstanding Clean Air Act (Act) requirements have not been met. This memo provides guidance on the statutorily-mandated control programs that must be in the EPA-approved SIP if EPA is to approve the redesignation request. The Act's requirements for redesignation and a list of EPA's redesignation policy and guidance are included in Attachments A and B. In the future, further guidance may be provided for redesignations submitted after November 15, 1993.

## 2

Note that this represents a departure from earlier guidance 1 

## for part D new source review (NSR) regulations. II. Policy Summary Section 107(d)(3)(E)(v) of the Act as amended (amended Act) provides that the State must have met all applicable requirements of section 110 and part D in order to be redesignated. Furthermore, section 107(d)(3)(E)(ii) provides that the State must have a fully-approved SIP for the area seeking redesignation. The EPA is interpreting these section 107 provisions to require satisfactory completion of the current Act planning requirements. Specifically, before EPA can act favorably upon any State redesignation request, the statutorily-mandated control programs of section 110 and part D (that were due prior to the time of the redesignation request) must have been adopted by the State and approved by EPA into the SIP. Thus, with respect to redesignation requests submitted on or after the Act's deadline for submittal of the required programs, States must generally adopt and provide for implementation of their regulations for all of the programs that were due. States must submit these plans to EPA for incorporation into the SIP. 1 

## This would include such requirements as emissions inventories and/or emission statements. Such requirements must be met in order for the area to have a fully-approved SIP that meets all requirements applicable to the area under section 110 and part D. The amended Act, however, also provides that upon redesignation, a State may move measures from the implemented SIP to the contingency plan portion of the SIP if the State demonstrates that such measures are not needed for maintaining the NAAQS. Many areas sought redesignation at or about the same time they were required to adopt and implement the requirements due on November 15, 1992. In many instances, the State will be able to immediately move these measures to the contingency plan without implementation. III. Exceptions to Policy The EPA decided to review the requirements to determine if something less than full adoption of these regulations would be

## 3

acceptable under the Act for areas seeking redesignation. Exceptions to this policy on the States' need to complete the full planning and adoption process for the November 15, 1992 mandated programs are very limited. The language in the Act allows a degree of flexibility in only four program areas. These are: (1) basic inspection and maintenance (I/M), (2) annual updates of vehicle miles traveled (VMT) forecasts and annual estimates of actual VMT for CO nonattainment areas, (3) nitrogen oxides (NOx) reasonably available control technology (RACT), and (4) small business programs (SBP). These exceptions are only applicable in areas for which EPA approves a redesignation. The States should be aware that if EPA denies a redesignation request, rules submitted in accordance with this guidance may also be disapprovable. Finally, because EPA anticipates issuing onboard regulations by January 1994, States seeking redesignation of areas classified as moderate may have some flexibility with respect to the Stage II requirement. Our guidance for State submittals covering these four programs is described in the following paragraphs. Basic I/M For areas where maintenance plans do not rely on implementation of a basic I/M program immediately following redesignation, the I/M component of the SIP should include: 1. Legislative authority for basic I/M such that implementing regulations can be adopted without any further legislative action. 2. A provision in the SIP providing that basic I/M be placed in the contingency measures portion of the maintenance plan upon redesignation. 3. An enforceable schedule and commitment by the Governor or his designee for adoption and implementation of a basic I/M program upon a specified, appropriate triggering event. Note that, for purposes of consideration of a redesignation request submitted after November 15, 1992, the commitment as described in the I/M regulation (see 57 FR 52950, November 5, 1992) is not sufficient to meet the Act's requirement for a fully-approved SIP. In addition, please note that, EPA's final I/M regulations in 40 CFR part 51 require a fully-adopted I/M program by November 15, 1993. At this time, our preliminary interpretative

## 4

Note that the section 182(f) exemption for NOx RACT and NSR 2 

## requirements described in this section is applicable only for guidance on basic I/M in this memo is not discussed in the I/M regulations. Therefore, EPA is proceeding to establish this interpretation through regulatory action, thus enabling EPA to accept legislative authority and a commitment to adopt and implement basic I/M regulations for those areas being redesignated to attainment. VMT Forecasting The VMT forecasting SIP for CO should include: 1. Annual forecasts of VMT (i.e., average daily VMT for the peak 3-month CO seasons for 1993, 1994, and 1995 in moderate areas above 12.7 ppm, and until 2000 in serious areas). 2. An enforceable commitment by the Governor or his designee to estimate actual annual VMT for each of these years (by September 30 of the following year) and to update the forecast of the VMT in the remaining years. 3. A request that the commitment be moved to the contingency plan portion of the SIP upon redesignation, becoming a contingency provision triggered by a specified triggering event. 4. Adopted contingency measures to reduce CO emissions. The implementation of such measures is contingent upon either: (a) an annual estimate of actual VMT or updated forecast of VMT exceeding the previous forecast for that year, or (b) the area failing to attain by the CO attainment deadline. These contingency measures must meet the requirements of section 187(a)(3) as interpreted by the April 16, 1992, "General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990," including the requirement that no further action by the State is needed for them to take effect. NOx RACT Section 182(f) provides that States may request an exemption from the NOx RACT requirements. The NOx RACT requirements of section 182(f) do not apply if additional reductions of NOx would not contribute to attainment. In an area that did not implement 2

## 5

States outside an ozone transport region, since only those States fall under the section 182(f) "contribute to attainment" provision. the section 182(f) NOx requirement but did meet the ozone standard, as demonstrated by adequate monitoring data consistent with EPA guidance, it is clear that the additional NOx reductions required by section 182(f) would not contribute to attainment, although they might contribute to maintenance. Therefore, EPA believes that if a State submits a redesignation request along with a section 182(f) exemption request based on monitoring data demonstrating attainment of the ozone NAAQS, further documentation is not required. The State may follow one of two approaches in making such a submittal: 1. Submit a redesignation request along with a section 182(f) exemption request based solely upon monitoring data showing that the area's air quality is meeting the ozone NAAQS; andsubmit a maintenance plan SIP revision, which includes a NOx RACT program as a contingency measure. In lieu of adopted NOx RACT rules, such a NOx RACT program may consist of an enforceable schedule and commitment by the Governor or his designee to adopt and implement the NOx RACT rules upon a specified, appropriate triggering event. 2. An exemption request based on both ambient monitoring and urban airshed modeling consistent with EPA guidance that shows additional NOx reductions would not contribute to attainment in the area. In this case, NOx RACT rules do not have to be included as a contingency measure of the maintenance plan. SBP For several reasons, the Act can be interpreted as not requiring the section 507 SBP submittal in order for EPA to approve a redesignation request. The SBP submittal is required regardless of whether there are any designated nonattainment areas within the State. In addition, the SBP is not a control measure intended to contribute to the emission reductions achieved by an area; rather it is a service provided to help small businesses comply with requirements of the Act. For the above reasons, EPA is interpreting the SBP as not being an applicable requirement for any specific nonattainment area that is seeking redesignation. However, EPA will continue to ensure that States make SBP submittals in a timely fashion. Stage II Vapor Recovery

## 6

Stage II vapor recovery remains an applicable requirement for moderate ozone nonattainment areas until EPA promulgates onboard vapor recovery regulations. Section 202(a)(6) of the Act provides that once onboard regulations are promulgated, the Stage II regulations required under section 182(b)(3) are no longer applicable for moderate ozone nonattainment areas. Therefore, final redesignation for a moderate nonattainment area that occurs after EPA's onboard regulations are promulgated does not have to include a Stage II SIP control program. For redesignation requests that are submitted before EPA promulgates onboard rules and that do not include Stage II rules for moderate areas, Regional Offices may prepare rulemaking actions proposing to approve the redesignation, if appropriate, as long as final approval occurs after EPA promulgates onboard regulations.

IV. Coordination of SIP Submittals and Redesignation Requests If the State elects to follow the approach above, the State should submit the SIP control program as described above along with the redesignation request and maintenance plan. The EPA will review the required SIP submittal(s) against EPA policy and guidance and in coordination with the redesignation request and maintenance plan. Approvability of the redesignation is directly related to the approvability of the SIP submittals (i.e., EPA is precluded from approving a redesignation to attainment if the SIP is not approvable). As a general policy, a State may not relax the adopted and implemented SIP for an area upon the area's redesignation to attainment. States should continue to implement existing control strategies in order to maintain the standard. However, section 175A recognizes that States may be able to move SIP measures to the contingency plan upon redesignation if the State can adequately demonstrate that such action will not interfere with maintenance of the standard. The type of demonstration necessary is dependent upon the pollutant for which the area has been redesignated to attainment. In order to make such a demonstration for an area redesignated to attainment for CO, EPA believes that the State could submit a revised control strategy demonstration showing that the measure is not necessary to maintain the standard. For ozone, the State would need to submit an attainment modeling demonstration consistent with EPA's current "Guideline on Air

## 7

Quality Models," showing that the control measure is not needed to maintain the standard. The EPA intends to be very cautious in approving such revisions in cases where the control measures were implemented during the time the area attained the standard; the State's demonstration should indicate an ample margin of safety with respect to maintenance of the standard. V. Conclusion In summary, full adoption of all of the statutorily-required programs, as well as a schedule and an enforceable commitment for an implementation date, are necessary for redesignation to attainment from nonattainment for ozone or CO if the redesignation request is submitted after the statutory due date for the program. The few exceptions to this requirement are basic I/M, annual updates of VMT forecasts, and estimates of actual VMT, NOx RACT, and SBP.

## Attachment A

Criteria For Redesignation Under Section 107(d) Section 107(d)(3)(E) of the Act states five criteria that must be met before the Administrator may redesignate an area to attainment. The criteria are: 1. The EPA has determined that the NAAQS have been attained. 2. The applicable implementation plan has been fully approved by EPA under section 110(k). 3. The EPA has determined that the improvement in air quality is due to permanent and enforceable reductions in emissions. 4. The State has met all applicable requirements for the area under section 110 and part D. 5. The EPA has fully approved a maintenance plan, including a contingency plan, for the area under section 175A.

### Air Quality Designations and Classifications for the 8-Hour Ozone National Ambient Air Quality Standards; Early Action Compact Areas With Deferred Effective Dates AGENCY 

### : Environmental Protection Agency (EPA). ACTION 

### : Final rule. SUMMARY 

### : This rule sets forth the air quality designations and classifications for every area in the United States, including Indian country, for the 8-hour ozone national ambient air quality standard. We are issuing this rule so that citizens will know whether the air where they live and work is healthful or unhealthful and to establish the boundaries and classifications for areas designated as nonattainment. Children are at risk when exposed to ozone pollution because their lungs are still developing, people with existing respiratory disease are at risk, and even healthy people who are active outdoors can experience difficulty breathing when exposed to ozone pollution. In this document, EPA is also promulgating the first deferral of the effective date, to September 30, 2005, of the nonattainment designation for Early Action Compact areas that have met all milestones through March 31, 2004. Finally, we are inviting States to submit by July 15, 2004, requests to reclassify areas if their design value falls within five percent of a high or lower classification. This rule does not establish or address State and Tribal obligations for planning and control requirements which apply to nonattainment areas for the 8-hour ozone standard. Two separate rules, one of which is also published today, set forth the planning and control requirements which apply to nonattainment areas for this standard. The second rule will be published at a later date. EFFECTIVE DATE 

### : This final rule is effective on June 15, 2004. ADDRESSES

The purpose of this document is to announce and promulgate designations, classifications, and boundaries for areas of the country with respect to the 8-hour ground-level ozone National Ambient Air Quality Standard (NAAQS) in accordance with the requirements of the CAA. We took several steps to announce that this rule was available. We posted the rule on several EPA Web sites and provided a copy of the rule, which was signed by the Administrator on April 15, 2004, to States and Tribes. III. How Is Ground-Level Ozone Formed?

Ground-level ozone (sometimes referred to as smog) is formed by the reaction of volatile organic compounds (VOCs) and oxides of nitrogen (NOX

### ) in the atmosphere in the presence of sunlight. These two pollutants, often referred to as ozone precursors, are emitted by many types of pollution sources, including on-road and off-road motor vehicles and engines, power plants and industrial facilities, and smaller sources, collectively referred to as area sources. Ozone is predominately a summertime air pollutant. Changing weather patterns contribute to yearly differences in ozone concentrations from region to region. Ozone and the pollutants that form ozone also can be transported into an area from pollution sources found hundreds of miles upwind. IV. What Are the Health Concerns Addressed by the 8-Hour Ozone Standard?

During the hot summer months, ground-level ozone reaches unhealthy levels in several parts of the country. Ozone is a significant health concern, particularly for children and people with asthma and other respiratory diseases. Ozone has also been associated with increased hospitalizations and emergency room visits for respiratory causes, school absences, and reduced activity and productivity because people are suffering from ozone-related respiratory symptoms.

Breathing ozone can trigger a variety of health problems. Ozone can irritate the respiratory system, causing coughing, throat irritation, an uncomfortable sensation in the chest, and/or pain when breathing deeply. Ozone can worsen asthma and possibly other respiratory diseases, such as bronchitis and emphysema. When ozone levels are high, more people with asthma have attacks that require a doctor’ s attention or the use of additional medication. Ozone can reduce lung function and make it more difficult to breathe deeply, and breathing may become more rapid and shallow than normal, thereby limiting a person ’ s normal activity. In addition, breathing ozone can inflame and damage the lining of the lungs, which may lead to permanent changes in lung tissue, irreversible reductions in lung function, and a lower quality of life if the inflammation occurs repeatedly over a long time period (months, years, a lifetime). People who are particularly

## 23860 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations susceptible to the effects of ozone include children and adults who are active outdoors, people with respiratory disease, such as asthma, and people with unusual sensitivity to ozone.

_index.html. V. What Is the Chronology of Events Leading Up to This Rule?

This section summarizes the relevant activities leading up to today ’ s rule, including promulgation of the 8-hour ozone NAAQS and litigation challenging that standard. The CAA establishes a process for air quality management through the NAAQS. Area designations are required after promulgation of a new or revised NAAQS. In 1979, we promulgated the 0.12 parts per million (ppm) 1-hour ozone standard, (44 Federal Register 8202, February 8, 1979). On July 18, 1997, we promulgated a revised ozone standard of 0.08 ppm, measured over an 8-hour period, i.e., the 8-hour standard (62 FR 38856). The 8-hour standard is more protective of public health and more stringent than the 1-hour standard. The NAAQS rule was challenged by numerous litigants and in May 1999, the U.S. Court of Appeals for the D.C. Circuit issued a decision remanding, but not vacating, the 8-hour ozone standard. Among other things, the Court recognized that EPA is required to designate areas for any new or revised NAAQS in accordance with the CAA and addressed a number of other issues, which are not related to designations. American Trucking Assoc. v. EPA, 175 F.3d 1027, 1047
– 48, on rehearing 195 F.3d 4 (D.C. Cir., 1999). We sought review of two aspects of that decision in the U.S. Supreme Court. In February 2001, the Supreme Court upheld our authority to set the NAAQS and remanded the case back to the D.C. Circuit for disposition of issues the Court did not address in its initial decision. Whitman v. American Trucking Assoc., 121 S. Ct. 903, 911 – 914, 916 – 919 (2001) (Whitman). The Supreme Court also remanded the 8- hour implementation strategy to EPA. In March 2002, the D.C. Circuit rejected all remaining challenges to the 8-hour ozone standard. American Trucking Assoc. v. EPA, 283 F.3d 355 (D.C. Cir. 2002).

The process for designations following promulgation of a NAAQS is contained in section 107(d)(1) of the CAA. For the 8-hour NAAQS, the Transportation Equity Act for the 21st Century (TEA
– 21) extended by 1 year the time for EPA to designate areas for the 8-hour NAAQS. 1 

### Thus, EPA was required to designate areas for the 8- hour NAAQS by July 2000. However, HR3645 (EPA ’ s appropriation bill in 2000) restricted EPA ’ s authority to spend money to designate areas until June 2001 or the date of the Supreme Court ruling on the standard, whichever came first. As noted earlier, the Supreme Court decision was issued in February 2001. In 2003, several environmental groups filed suit in district court claiming EPA had not met its statutory obligation to designate areas for the 8-hour NAAQS. We entered into a consent decree, which requires EPA to issue the designations by April 15, 2004. VI. What Are the Statutory Requirements for Designating Areas and What Is EPA’s Policy and Guidance for Determining Nonattainment Area Boundaries for the 8-Hour Ozone NAAQS?

This section describes the statutory definition of nonattainment and EPA ’ s guidance for determining air quality attainment and nonattainment areas for the 8-hour ozone NAAQS. In March 2000 2 

### and July 2000 3 

### we issued designation guidance on how to determine the boundaries for nonattainment areas. In that guidance, we rely on the CAA definition of a nonattainment area that is defined in section 107(d)(1)(A)(i) as an area that is violating an ambient standard or is contributing to a nearby area that is violating the standard. If an area meets this definition, EPA is obligated to designate the area as nonattainment.

In making designations and classifications, we use the most recent 3 years of monitoring data. 4 

### Therefore, today ’ s designations and classifications are generally based on monitoring data collected in 2001
– 2003 although other relevant years of data may have been used in certain circumstances. Once we determine that a monitor is recording a violation, the next step is to determine if there are any nearby areas that are contributing to the violation and

3 Memorandum of July 18, 2000, from John S. Seitz, ‘‘ Guidance on 8-Hour Ozone Designations for Indian Tribes. ’’

4 To determine whether an area is attaining the 8- hour ozone NAAQS, EPA considers the most recent 3 consecutive years of data in accordance with 40 Code of Federal Regulations (CFR) part 50, appendix I. 

### include them in the designated nonattainment area.

For guidance on determining the nonattainment boundary for the 8-hour ozone standard, we look to CAA section 107(d)(4) that established the Consolidated Metropolitan Statistical Area (CMSA) or Metropolitan Statistical Area (MSA) presumptive boundary for more polluted areas when we promulgated our designation actions in 1991 for the 1-hour ozone standard. In our guidance on determining nonattainment area boundaries for the 8-hour ozone standard, we advised States that if a violating monitor is located in a CMSA or MSA (as defined by the Office of Management and Budget (OMB) in 1999), the larger of the 1-hour ozone nonattainment area or the CMSA or MSA should be considered in determining the boundary of a nonattainment area. The actual size of the nonattainment area may be larger orsmaller, depending on air qualityrelated technical factors contained in our designation guidance. We start with counties in the CMSA or MSA because that area, defined by OMB, generally shares economic, transportation, population and other linkages that are similar to air quality related factors that produce ozone pollution. Also, many CMSAs and MSAs generally are associated with higher levels of ozone concentrations and ozone precursor emissions than areas that are not in or near CMSAs or MSAs.

In June 2003, OMB released a new list of statistical areas. This release was so late in the designation process that we determined that it would be disruptive and unfair to the States and Tribes to revise our guidance. However, we believe it is necessary to evaluate all counties in and around an area containing a monitor that is violating the standard, pursuant to our guidance to consider nearby areas that are contributing to a violation in determining the boundaries of the nonattainment area.

Once a CMSA, MSA or single county area is determined to contain a monitor that is violating the standard, the area can be evaluated using all applicable suggested air quality related factors in our guidance. The factors can be used to justify including counties outside the CMSA or MSA or excluding counties in the CMSA or MSA. The factors were compiled based on our experience in designating areas for the ozone standard in March 1978 and November 1991 and by looking to the CAA, section 107(d)(4), which states that the Administrator and the Governor shall consider factors such as population density, traffic congestion, commercial

### Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations 

## 23861 development, industrial development, meteorological conditions, and pollution transport. State and local agencies also had extensive input into compiling the factors.

The factors are: (1) Emissions and air quality in adjacent areas (including adjacent CMSAs and MSAs),

(2) Population density and degree of urbanization including commercial development (significant difference from surrounding areas),

(3) Monitoring data representing ozone concentrations in local areas and larger areas (urban or regional scale),

(4) Location of emission sources (emission sources and nearby receptors should generally be included in the same nonattainment area),

(5) Traffic and commuting patterns, (6) Expected growth (including extent, pattern and rate of growth),

(7) Meteorology (weather/transport patterns),

(8) Geography/topography (mountain ranges or other air basin boundaries),

(9) Jurisdictional boundaries (e.g. , counties, air districts, existing 1-hour nonattainment areas, Reservations, etc.),

(10) Level of control of emission sources, and,

(11) Regional emissions reductions (e.g. , NOX 

### State Implementation Plan (SIP) Call or other enforceable regional strategies).

When evaluating the air quality factors for individual areas, we took into account our view that data recorded by an ozone air quality monitor in most cases represents air quality throughout the area in which it is located. In addition, we used the county (or in the case of parts of New England, the township) as the basic jurisdictional unit in determining the extent of the area reflected by the ozone monitor data. As a result, if an ozone monitor was violating the standard based on the 2001 – 2003 data, we designated the entire county as nonattainment. There were some exceptions to this rule: in cases where a county was extremely large as in the West; where a geographic feature bifurcated a county, leading to different air quality in different parts of the county; and where a mountain top monitor reflected the air quality data only on the mountain top and not in lower elevation areas.

After identifying the counties with violating monitors, we then determined which nearby counties were not monitoring violations but were nonetheless contributing to the nearby violation. We considered each of the 11 factors in making our contribution assessment, including emissions, traffic patterns, population density, and area growth. In some cases, in considering these factors, as well as information and recommendations provided by the State, we determined that only part of a county was contributing to the nearby nonattainment area. In addition, in certain cases, we determined that a county without an ozone monitor should be designated nonattainment because contiguous counties have monitors that are violating the standard. In at least two instances, we determined that a part of a county with no monitor, but with a large emission source that did not have state-of-the-art controls, contributes to a nearby violation. In some instances, if a State had requested that we continue to use the 1-hour ozone nonattainment boundary for an area, we continued to use that boundary in determining the size of the 8-hour nonattainment area.

The EPA cannot rely on planned ozone reduction strategies in making decisions regarding nonattainment designations, even if those strategies predict that an area may attain in the future. We recognize that some areas with a violating monitor may come into attainment in the future without additional local emission controls because of State and/or national programs that will reduce ozone transport. While we cannot consider these analyses in determining designations, we intend to expedite the redesignation of the areas to attainment once they monitor clean air. We also intend to apply our policy which streamlines the planning process for nonattainment areas that are meeting the NAAQS. 5



### We believe that area-to-area variations must be considered in determining whether to include a county as contributing to a particular nonattainment problem. Thus, our guidance does not establish cut-points for how a particular factor is applied, e.g. , it does not identify a set amount of VOC or NOX 

### emissions or a specific level of commuting population that would result in including a county in the designated nonattainment area. For example, a county with a large source or sources of NOX 

### emissions may be considered as a contributing county if it is upwind, rather than downwind, of a violating monitor. Additionally, a county with VOC emissions of 5,000 tons per year (tpy) might be viewed differently if the total VOC emissions of the area are 15,000 tpy rather than 30,000 tpy. We analyzed the

5 Memorandum of May 10, 1995, from John S. Seitz, ‘‘ Reasonable Further Progress, Attainment Demonstration, and Related Requirements for Ozone Nonattainment Areas Meeting the Ozone National Ambient Air Quality Standard. ’’ 

### information provided by each State or Tribe in its recommendation letter, or subsequently submitted, along with any other pertinent information available to EPA, to determine whether a county should be designated nonattainment. We evaluated each State or Tribal designation recommendation in light of the 11 factors, bringing to bear our best technical and policy judgement. If the result of the evaluation is that a county, whether inside or outside of the CMSA or MSA, is contributing to the violation, we designated the area as nonattainment. VII. What Are the CAA Requirements for Air Quality Designations and What Actions Has EPA Taken To Meet the Requirements?

In this part, we summarize the provisions of section 107(d)(1) of the CAA that govern the process States and EPA must undertake to recommend and promulgate designations. Following promulgation of a standard, each State Governor or Tribal leader has an opportunity to recommend air quality designations, including appropriate boundaries, to EPA. No later than 120 days prior to promulgating designations, we must notify States or Tribes if we intend to make modifications to their recommendations and boundaries as we deem necessary. States and Tribes then have an opportunity to provide a demonstration as to why the proposed modification is inappropriate. Whether or not a State or Tribe provides a recommendation, EPA must promulgate the designation it deems appropriate.

In June 2000, we asked each State and Tribal Governor or Tribal leader to submit their designation recommendations and supporting documentation to EPA. Because of the uncertainties due to the ongoing litigation on the ozone standard, we did not notify States and Tribes of any intended modifications and did not designate areas at that time. After the legal challenges to the ozone NAAQS were resolved, we requested that States and Tribes provide updated recommendations and any additional supporting documentation by July 15, 2003. EPA published a Notice of Availability (NOA) announcing the availability of the State and Tribal recommendations in the FR on September 8, 2003 (68 FR 52933). After carefully evaluating each recommendation and the supporting documentation, on December 3, 2003, we wrote a letter to each State and Tribe notifying them if we intended to make a modification to their recommendation and indicating the area with which we agreed with their recommendation. We

## 23862 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations provided an opportunity until February 6, 2004, for a demonstration as to why our modification was not appropriate. A NOA announcing the availability of our letters was published in the FR on December 10, 2003 (68 FR 68805). In response to our December 3, 2003 letters, we received letters and demonstrations from many States and Tribes on why our modifications were not appropriate. We evaluated each letter and all of the timely technical information provided to us before arriving at the final decisions reflected in today ’ s rule. Some of the designations reflect our modifications to the State or Tribes ’ recommendations. Throughout the designation process, we have received letters from other interested parties. We have placed these letters and our responses to the substantive issues raised by them in the docket. Responses to significant comments received on EAC areas are summarized in this document.

Tribal designation activities are covered under the authority of section 301(d) of the CAA. This provision of the Act authorizes us to treat eligible Indian Tribes in the same manner as States. Pursuant to section 301(d)(2), we promulgated regulations known as the Tribal Authority Rule (TAR) on February 12, 1999, that specify those provisions of the CAA for which it is appropriate to treat Tribes as States, (63 FR 7254), codified at 40 CFR part 49 (1999). Under the TAR, Tribes may choose to develop and implement their own CAA programs, but are not required to do so. The TAR also establishes procedures and criteria by which Tribes may request from EPA a determination of eligibility for such treatment. The designations process contained in section 107(d) of the CAA is included among those provisions determined appropriate by us for treatment of Tribes in the same manner as States. As authorized by the TAR, Tribes may request an opportunity to submit designation recommendations to us. In cases where Tribes do not make their own recommendations, EPA, in consultation with the Tribes, will promulgate the designation we deem appropriate on their behalf. We invited all Tribes to submit recommendations to us. We worked with the Tribes that requested an opportunity to submit designation recommendations. Eligible Tribes could choose to submit their own recommendations and supporting

### documentation. We reviewed the recommendations made by Tribes and, in consultation with the Tribes, made modifications as deemed necessary. Under the TAR, Tribes generally are not subject to the same submission schedules imposed by the CAA on States. However, we worked with Tribes in scheduling interim activities and final designation actions because of the consent decree obligating us to have a signed rule designating areas by April 15, 2004.

Today ’ s designation action is a final rule establishing designations for all areas of the country. Today ’ s action also sets forth the classifications for subpart 2 ozone nonattainment areas. Section 181(a) provides that areas will be classified at the time of designation. This rulemaking fulfills those requirements. Classifications are discussed below. A. Where Can I Find Information Forming the Basis for This Rule and Exchanges Between EPA, States, and Tribes Related to This Rule?

Discussions concerning the basis for today ’ s actions and decisions are provided in the technical support document (TSD). The TSD, along with copies of all of the above mentioned correspondence, other correspondence between the States, Tribes, interested parties, and EPA regarding this process and guidance memoranda are available for review in the EPA Docket Center listed above in the addresses section of this document and on our designation Web site at: http://www.epa.gov/oar/ oaqps/glo/designations. State specific information is available at the EPA Regional Offices. VIII. What Are the CAA Requirements for Air Quality Classifications?

The CAA contains two sets of provisions— subpart 1 and subpart 2 — that address planning and control requirements for nonattainment areas. (Both are found in title I, part D.) Subpart 1 (which we refer to as ‘‘ basic ’’ nonattainment contains general, less prescriptive, requirements for nonattainment areas for any pollutant — including ozone
— governed by a NAAQS. Subpart 2 (which we refer to as ‘‘ classified ’’ nonattaiment) provides more specific requirements for ozone nonattainment areas. 6 

### Some areas will be subject only to the provisions of subpart 1. Other areas will be subject to NAAQS, design value is defined at 40 CFR 51.900(d).

8 In the Phase 2 implementation rule, we will address the control obligations that apply to areas under both subpart 1 and subpart 2. 

### the provisions of subpart 2. Section 172(a)(1) provides that EPA has the discretion to classify areas subject only to subpart 1. Under subpart 2, areas will be classified based on each area’ s design value. Control requirements are linked to each classification. Areas with more serious ozone pollution are subject to more prescribed requirements. The requirements are designed to bring areas into attainment by their specified attainment dates.

Under our 8-hour ozone implementation rule, signed on April 15, 2004, an area will be classified under subpart 2 based on its 8-hour design value 7 

### if it has a 1-hour design value at or above 0.121 ppm (the lowest 1-hour design value in Table 1 of subpart 2). All other areas will be covered under subpart 1. Section 172(a)(1) provides EPA with discretion whether to classify areas under subpart 1 and we are not classifying subpart 1 areas, with one exception. As noted in EPA ’ s final rule on implementing the 8- hour ozone standard (Phase 1 implementation rule), we are creating an overwhelming transport classification that will be available to subpart 1 areas that demonstrate they are affected by overwhelming transport of ozone and its precursors and demonstrate they meet the definition of a rural transport area in section 182(h). No subpart 1 areas are being classified in today ’ s action; however, for informational purposes, 8- hour ozone nonattainment areas covered under subpart 1 are identified as such in the classification column in 40 CFR part 81.

Any area with a 1-hour ozone design value (based on the most recent 3 years of data) that meets or exceeds the statutory level of 0.121 ppm that Congress specified in Table 1 of section 181 is classified under subpart 2 and is subject to the control obligations associated with its classification. 8 

### Subpart 2 areas are classified as marginal, moderate, serious, or severe based on the area’ s 8-hour design value calculated using the most recent 3 years of data. 9 

### As described in the Phase 1 implementation rule, since Table 1 is based on 1-hour design values, we promulgated in that rule a regulation translating the thresholds in Table 1 of section 181 from 1-hour values to 8- hour values. (See Table 1, below, ‘‘ Classification for 8-Hour NAAQS ’’ from 40 CFR 51.903.)

9 At this time, there are no areas with design values in the extreme classification for the 8-hour ozone standard.

### Five Percent Bump Down

Under section 181(a)(4), an ozone nonattainment area may be reclassified ‘‘ if an area classified under paragraph (1) (Table 1) would have been classified in another category if the design value in the area were 5 percent greater or 5 percent less than the level on which such classification was based. ’’ The section also states that ‘‘ In making such adjustment, the Administrator may consider the number of exceedances of the national primary ambient air quality standard for ozone in the area, the level of pollution transport between the area and other affected areas, including both intrastate and interstate transport, and the mix of sources and air pollutants in the area.

As noted in the November 6, 1991, FR on designating and classifying areas, the section 181(a)(4) provisions grant the Administrator broad discretion in making or determining not to make, a reclassification (56 FR 56698). As part of the 1991 action, EPA developed criteria (see list below) to evaluate whether it is appropriate to reclassify a particular area. In 1991, EPA approved reclassifications when the area met the first requirement (a request by the State to EPA) and at least some of the other criteria and did not violate any of the criteria (emissions, reductions, trends, etc.). We intend to use this method and these criteria once again to evaluate reclassification requests under section 181(a)(4), with the minor changes noted below. Because section 181(b)(3) provides that an area may request a higher classification and EPA must grant it, these criteria primarily focus on how we will assess requests for a lower classification. We further discuss bump ups below. Request by State: The EPA does not intend to exercise its authority to bump down areas on EPA ’ s own initiative. Rather, EPA intends to rely on the State to submit a request for a bump down. A Tribe may also submit such a request and, in the case of a multi-state nonattainment area, all affected States must submit the reclassification request.

Discontinuity: A five percent reclassification must not result in an illogical or excessive discontinuity relative to surrounding areas. In particular, in light of the area-wide nature of ozone formation, a reclassification should not create a ‘‘ donut hole’’ where an area of one classification is surrounded by areas of higher classification.

Attainment: Evidence should be available that the proposed area would be able to attain by the earlier date specified by the lower classification in the case of a bump down.

Emissions reductions: Evidence should be available that the area would be very likely to achieve the appropriate total percent emission reduction necessary in order to attain in the shorter time period for a bump down.

Trends: Near- and long-term trends in emissions and air quality should support a reclassification. Historical air quality data should indicate substantial air quality improvement for a bump down. Growth projections and emission trends should support a bump down. In addition, we will consider whether vehicle miles traveled and other indicators of emissions are increasing at higher than normal rates.

Years of data: For the 8-hour ozone standard, the 2001
– 2003 period is central to determining classification. This criterion has been updated to reflect the latest air quality data available to make the determinations within the statute’ s 90 day limitation. Limitations on Bump Downs

An area may only be reclassified to the next lower classification. An area cannot present data from other years as justification to be reclassified to an even lower classification. In addition, section 181(a)(4) does not permit moving areas from subpart 2 into subpart 1.

The EPA applied these criteria in 1991. For example, our action to bump down one area from severe to serious considered trends in population and emissions data, similarities to a nearby serious area, disparity with a nearby moderate area, the logical gradation of attainment deadlines proceeding outward from large metropolitan areas upwind, and the likelihood that the area would be able to attain the NAAQS in the shorter time frame. In approving a bump down to marginal, we noted that air quality trends showed improvement and recent air quality data indicated a marginal status. In denying a bump down, we analyzed local air quality trends and emission sources and considered long range transport from an area with a much later attainment deadline, which together made it unlikely the candidate area could attain the standard in the shorter time frame associated with the lower classification. Requests to bump down areas were also denied due, in part, to concern that transport of emissions from these areas would make it less likely that downwind nonattainment areas could attain the standards in a timely fashion. For additional information, see section 5, ‘‘ Areas requesting a 5% downshift per § 181(a)(4) and EPA ’ s response to those requests, ’’ of the Technical Support Document, October 1991 for the 1991 rule. [Docket A
– 90 – 42A.]

## 23864 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations Five Percent Bump Up

An ozone nonattainment area may also be reclassified under section 181(a)(4) to the next higher classification. For the reasons described below ( ‘‘ Other Reasons to Consider Bump Ups ’’ ), we believe some areas with design values close to the next higher classification may not be able to attain within the period allowed by their classification. We encourage States to request reclassification upward where the State finds that an area may need more time to attain than their classification would permit. In addition, EPA will consider bumping up areas subject to the five percent provision on our own initiative where there is evidence that an area is unlikely to attain within the period allowed by their classification. In making this determination, EPA would consider criteria similar to that listed above (adjusted to consider bump ups rather than bump downs) regarding discontinuity, attainment, emissions reduction and trends. The following areas have design values based on 2001 – 2003 data that fall within five percent of the next higher classification: Marginal areas within five percent of ModeratePortland, ME; Atlanta, GA; BeaumontPort Arthur, TX; and Norfolk, VA Moderate areas within five percent of Serious New York-New Jersey-Long Island,

NY-NJ-CT; Los Angeles-San Bernardino Counties (W. Mojave),CA; Baltimore, MD; ClevelandAkron-Lorain, OH; and HoustonGalveston-Brazoria, TX Serious areas within five percent of Severe-15 San Joaquin Valley, CA Calculation of Five Percent

For an area to be eligible for a bump down (or bump up) under section 181(a)(4), the area’ s design value must be within five percent of the next lower (or higher) classification. For example, an area with a moderate design value of 0.096 ppm (or less) would be eligible to request a bump down because five percent less than 0.096 ppm is 0.091 ppm, a marginal design value. 10 

### An area with a moderate design value of 0.102 ppm (or more) would be eligible for a bump up because five percent more than 0.102 ppm is 0.107 ppm, a serious design value. As a result, the following areas may be eligible to request a bump down: moderate areas with a design value of 0.096 ppm or less; serious areas

10 See EPA ’ s ‘‘ Guideline on Data Handling Conventions for the 8-Hour Ozone NAAQS ’’ (12 – 98) and appendix I to 40 CFR part 50. 

### with a design value of 0.112 ppm or less; and severe-17 areas with a design value of 0.133 ppm or less. Similarly, for bump ups, the following areas may be eligible: marginal areas with a design value of 0.088 ppm or more; moderate areas with a design value of 0.102 ppm or more; and serious areas with a design value of 0.115 ppm or more. Timing of the Five Percent Reclassifications

The notice of availability for this rule permits States to submit five percent reclassification requests within 30 days of the effective date of the designations and classifications. The effective date is June 15 which means that reclassification requests must be submitted by July 15, 2004. This relatively short time frame is necessary because section 181(a)(4) only authorizes the Administrator to make such reclassifications within 90 days after the initial classification. Thus, the Governor or eligible Tribal governing body of any area that wishes to pursue a reclassification should submit all requests and supporting documentation to the EPA Regional office by July 15, 2004. We will make a decision by September 15, 2004. Other Reasons To Consider Bump Ups

We encourage States to consider a voluntary bump up in cases where the State finds that an area may need more time to attain the 8-hour NAAQS than its classification would permit. In addition to the reclassification provision of section 181(a)(4), a State can request a higher classification under section 181(b)(3) of the CAA. This provision directs EPA to grant a State’ s request for a higher classification and to publish notice of the request and EPA ’ s approval. In addition, we are interpreting section 181(b)(3) to allow a State with an area covered under subpart 1 to request a reclassification to a subpart 2 classification.

We note that it is difficult to determine when an area will be able to attain the NAAQS in advance of State development of attainment plans. These plans are based on high-resolution local air quality modeling, refined emissions inventories, use of later air quality data, and detailed analyses of the impacts and costs of potential local control measures. As noted earlier, we are classifying nonattainment areas subject to subpart 2 based on the most recent ozone design values at the time of designation, the 2001
– 2003 period. Because of year-to-year variations in meteorology, this snapshot in time may not be representative of the normal magnitude of problems that some areas may face.

The EPA ’ s analysis in the proposed Interstate Air Quality Rule (IAQR) uses design values taken from the 2000
– 2002 period, rather than the 2001
– 2003 data used in the classification process. At the time the IAQR modeling was completed, 2000 – 2002 was the latest period which was available for determining designation compliance with the NAAQS. Concentrations of ozone in 2010 were estimated by applying the relative change in model predicted ozone from 2001 to 2010 with the 8- hour ozone design values (2000
– 2002). The IAQR base case analysis (which assumes existing control requirements only) projects ozone values in 2010 for several areas
— for example, Baltimore, Houston, New York and Philadelphia — that are high enough to suggest that the areas may be unable to attain by 2010, given our current information on the potential for additional controls. Yet, as a result of their classification, these areas are required to adopt a plan to attain the 8-hour ozone standard earlier than the 2010 ozone season. Atlanta has a projected 2010 ozone value much closer to the standard, but has an attainment date prior to the 2007 ozone season. Thus, the IAQR analysis, based on the 2000
– 2002 period, suggests that States should evaluate whether certain areas may need more time to attain. States should consider in their local air quality modeling whether an area’ s projected air quality level would be higher if the projection were based on different three-year base periods. While we recognize that future local analyses for specific nonattainment areas may show different results than the regional IAQR analysis, we encourage States to consider requesting a higher classification for areas that the State believes need more time to attain, especially in cases where existing modeling analysis and information on potential controls suggests more time is needed than their classification would permit. IX. What Action Is EPA Taking To Defer the Effective Date of Nonattainment Designations for EAC Areas?

This section discusses EPA ’ s final action with respect to deferring the effective date of nonattainment designations for areas of the country that do not meet the 8-hour ozone NAAQS and are participating in the EAC program. By December 31, 2002, we entered into compacts with 33 communities. To receive this deferral, these EAC areas have agreed to reduce ground-level ozone pollution earlier

### Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations 

## 23865 than the CAA would require. This final rule for compact areas addresses several key aspects of the proposed rule, including deferral of the effective date of nonattainment designation for certain compact areas; progress of compact areas toward completing their milestones; final action for compact areas; EPA ’ s schedule for taking further action to continue to defer the effective date of nonattainment designations, if appropriate; and consequences for compact areas that do not meet a milestone. In this action, we have added regulatory text to clarify specific requirements in part 81 for compact areas and to identify actions that we will take to address any failed milestones. Finally, we have responded to the significant comments on the proposed rule. A. When Did EPA Propose the First Deferred Effective Date of Nonattainment Designations?

On December 16, 2003 (68 FR 70108), we published a proposed rule to defer the effective date of air quality nonattainment designations for EAC areas that do not meet the 8-hour ozone NAAQS. The proposal also described the compact approach, the requirements for areas participating in the program, and the impacts of the program on these areas. Compact areas have agreed to reduce ground-level ozone pollution earlier than the CAA would require. Please refer to the proposed rule for a detailed discussion and background information on the development of the compact program, what compact areas are required to do, and the impacts of the program.

Table 2 describes the milestones and submissions that compact areas are required to complete to continue eligibility for a deferred effective date of nonattainment designation for the 8- hour ozone standard.

### B. What Progress Are Compact Areas Making Toward Completing Their Milestones?

In this section we describe the status of the compact areas ’ progress toward meeting their compact milestones. In general, these areas have made satisfactory progress toward timely completion of their milestones. As reported in the December 16, 2003 proposal, all 33 communities met the June 16, 2003 milestone, which required areas to submit a list and description of local control measures each area considered for adoption and implementation. A compiled list, as well as highlights, of these local measures is found on EPA ’ s Web site for compact areas at http://www.epa.gov/ ttn/ naaqs/ozone/eac/ index.htm#EACsummary. By December 31, 2003, compact areas reported the status of these measures by identifying the local measures still under consideration at that time, the estimated emissions reductions expected from these measures, and the schedule for implementation. A summary of the local measures as reported in December 2003 is presented on EPA ’ s EAC Web site at http://www.epa.gov/ttn/ naaqs/ozone/ eac/20031231 _ eac

_list.pdf. By March 31, 2004, compact areas submitted local plans, which included measures for adoption that are specific, quantified, and permanent, and if approved by EPA, will be federally enforceable as part of the SIP. These plans also included specific implementation dates for the local controls, as well as a technical assessment of whether the area could attain the 8-hour ozone NAAQS by the December 31, 2007 milestone, which is described in Table 2. The local plans for all compact areas are posted on the EAC Web site at: http://www.epa.gov/ttn /naaqs/ozone/eac/#List.

The EPA reviewed all of the local plans submitted by March 31, 2004 and determined that most of the plans were acceptable. With respect to control strategies, a number of areas are relying on measures to be adopted by the State, and are committed to implement these measures by 2005. In many cases, particularly in the southeast, the MAC areas demonstrated that they can attain the 8-hour ozone standard by December 2007 without implementation of local controls. In general, the technical demonstrations of attainment were acceptable; however, some of the 33 communities did not project attainment in 2007 (the attainment test) based on modeling, unless they considered additional factors to supplement their analysis (i.e. , weight of evidence). In evaluating a State’ s weight of evidence determination for an area, we consider the results of the modeled, attainment test — for all EAC areas, a demonstration of attainment in 2007
— along with additional information, such as predicted air quality improvement, meteorological influences, and additional measures not modeled. Our modeling guidance indicates that the farther an area is from the level of the standard, the more compelling the additional information needs to be in order to demonstrate that the area will attain the standard. Based on our analysis of the technical information provided, we believe that some areas did not present as strong a case as other areas to demonstrate attainment by December 2007. Three areas in Tennessee, Knoxville, Memphis and Chattanooga each developed attainment demonstrations that generally conform to our modeling guidance. However, in reviewing and analyzing the local plans for these areas, we determined that Knoxville, Memphis and Chattanooga did not pass the modeled attainment test and the predicted air quality improvement test. In addition, our review of meteorological influences for the three areas was inconclusive; and these areas did not provide additional measures not already modeled. In

## 23866 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations addition to the technical analysis, we reviewed the strength of the control strategies each EAC area proposed in their March 31, 2004 plans. We determined that the control measures submitted by these three areas could have been strengthened, and the Agency expected more local measures. Therefore, EPA determined that the States ’ technical assessments for each of these areas and their suite of measures were not acceptable. The only other two compact areas that did not pass the modeled attainment test, the Denver, Colorado area and the Triad (Greensboro-Winston-Salem-High Point), North Carolina area, provided more meaningful local control measures than the three Tennessee compact areas. Based on our review and evaluation of these local plans, we have determined that Knoxville, Memphis and Chattanooga do not meet the March 31, 2004 milestone. In accordance with the Early Action Protocol and agency guidance, all EAC areas must meet all compact milestones, including this most recent one, to be eligible for the deferred effective date of designation. Consequently, today, these three areas are being designated nonattainment, effective June 15, 2004, and are subject to full planning requirements of title I, part D of the CAA. For the other EAC areas not meeting the 8-hour ozone standard, which we determined have complied with the March 2004 milestone, are being designated nonattainment with a deferred effective date of September 30, 2005. By that date, we intend to take notice and comment rulemaking and promulgate approval or disapproval of these plans as SIP revisions. The local plans that are approved at that time will be eligible for an extension of the deferred effective date. If EPA disapproves any local plans at that time, the nonattainment designation will become effective immediately. Our evaluations of all local plans submitted by March 31, 2004, are included in the TSD for this rulemaking.

Table 3 lists the EAC areas and their air quality designation for the 8-hour ozone standard by county. The table in Part 81 lists 8-hour ozone designations for all areas of the country.

## 23869 compact area that does not meet the 8- hour ozone NAAQS and would otherwise be designated nonattainment, but has met all compact milestones through the March 31, 2004 submission. 11 

### We are deferring until September 30, 2005, the effective date of the 8-hour ozone nonattainment designation for these compact area counties which are listed in 40 CFR part 81 (included at the end of this document).

As described earlier in this notice, we analyzed information provided by the States to determine whether a county should be included as part of a designated nonattainment area. This information included such factors as population density, traffic congestion, meteorological conditions, and pollution transport. We analyzed the factors for each county participating in an EAC to determine whether a county should be included in the nonattainment area. Therefore, some portions of compact areas are designated unclassifiable/attainment and some are designated nonattainment.

The EAC areas that EPA is designating in today ’ s rule as attainment for the 8- hour ozone NAAQS have agreed to continue participating in their compacts and meet their obligations on a voluntary basis. However, two of the five counties in the compact for the Mountain Area of Western North Carolina have decided to withdraw because the area is monitoring attainment. The remaining three counties are continuing to participate in the agreement. D. What Is EPA ’ s Schedule for Taking Further Action To Continue To Defer the Effective Date of Nonattainment Designation for Compact Areas?

As discussed in the proposed rule, prior to the time the first deferral expires, we intend to take further action to propose and, as appropriate, promulgate a second deferred effective date of the nonattainment designation for those areas that continue to fulfill all compact obligations. Prior to the time the second deferral expires, we would propose and, as appropriate, promulgate a third deferral for those areas that continue to meet all compact milestones. Before the third deferral expires shortly after December 31, 2007, we intend to determine whether the compact areas have attained the 8-hour ozone NAAQS and have met all compact milestones. By April 2008, we

11 In a few instances, some of the counties participating in EACs were determined not to be part of the nonattainment area and were designated attainment. In such cases, the effective date of the attainment designation is not deferred. 

### will issue our determination. If the area has not attained the standard, the nonattainment designation will take effect. If it has attained the standard, EPA will issue an attainment designation for the area. Any compact area that has not attained the NAAQS and has an effective nonattainment designation will be subject to full planning requirements of title I, part D of the CAA, and the area will be required to submit a revised attainment demonstration SIP within 1 year of the effective date of the designation. E. What Action Will EPA Take if a Compact Area Does Not Meet a Milestone?

As described in the December 16, 2003 proposed rule (68 FR 70111), the compact program was based on a number of principles as described in the EAC protocol. 12 

### One of these principles is to provide safeguards to return areas to traditional SIP requirements for nonattainment areas should an area fail to comply with the terms of the compact. For example, if a compact area with a deferred effective date fails to meet one of the milestones, we would take steps immediately to remove the deferred effective date of its nonattainment designation.

Today, we are promulgating regulatory text, which specifies the milestones that EAC areas are required to complete to be eligible for the deferred effective date, as well as certain actions that the Administrator will take when EAC areas either comply, or do not comply, with the terms of the compact. F. What Comments Did EPA Receive on the December 16, 2003 Proposal and on the June 2, 2003 Proposed Implementation Rule Specific to Compacts?

We received a number of comments on the proposed rule for compact areas. We have responded to the significant comments in this section. Our responses address various aspects of the compact program: (1) Legal concerns; (2) the designations process for EAC areas, including the anticipated schedule for removal of the deferred effective date of the nonattainment designation for any compact area that fails to meet a milestone; (3) concerns about the compact process; (4) transportation/

The EPA endorsed the Protocol in a letter dated June 19, 2002, from Gregg Cooke, Administrator, EPA Region VI, to Robert Huston, TCEQ. The Prtocol was revised December 11, 2002 based on comments from EPA. 

### fuels-related comments; and (5) need forregulatory language. Other compactrelated comments not addressed in this document are included in the RTC document, which is located in the docket for this rulemaking (OAR
– 2003 – 0090) and on EPA ’ s technical Web site for early action compacts at: http:// www.epa.gov/ttn/naaqs/ozone/eac/ #RMNotices.

In addition, we received a number of EAC-related comments on the June 2, 2003 proposal for implementing the 8- hour ozone standard. We have addressed these comments in the same EAC RTC document, which may be found at the location noted above. 1. Support for and Opposition to Early Action Compacts

Comment: Many commenters expressed support for the compact process, the goal of clean air sooner, the incentives and flexibility the program provides for encouraging early reductions of ozone-forming pollution, and the deferred effective date of nonattainment designation. However, a number of commenters opposed the EAC program. Several of these commenters expressed concern about the legality of the program and primarily about the deferral of the effective date of the nonattainment designation for these areas. Although all of these commenters were supportive of the goal of addressing proactively the public health concerns associated with ozone pollution, the commenters state that the EAC program is not authorized by the CAA. All of these commenters indicated that EPA lacks authority under the CAA to defer the effective date of a nonattainment designation. In addition, these commenters state that EPA lacks authority to enter into EACs areas and lacks authority to allow areas to be relieved of obligations under title I, part D of the CAA while these areas are violating the 8-hour ozone standard or are designated nonattainment for that standard.

Response: We continue to believe that the compact program, as designed, gives local areas the flexibility to develop their own approach to meeting the 8- hour ozone standard, provided the participating communities are serious in their commitment to control emissions from local sources earlier than the CAA would otherwise require. By involving diverse stakeholders, including representatives from industry, local and State governments, and local environmental and citizens ’ groups, a number of communities are discussing for the first time the need for regional cooperation in solving air quality problems that affect the health and

## 23870 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations welfare of its citizens. People living in these areas that realize reductions in pollution levels sooner will enjoy the health benefits of cleaner air sooner than might otherwise occur. In today ’ s rule we are codifying the specific requirements in part 81 of the CFR to clarify what is required of compact areas to be eligible for deferral of the effective date of their nonattainment designation and what actions EPA intends to take in response to areas that meet the milestones and areas that do not meet the milestones.

As discussed earlier in this notice, EPA and nine environmental organizations entered into a Consent Decree on March 13, 2003, which requires EPA to issue the designations by April 15, 2004. Related to that agreement, we have been discussing with these parties the actions that compact areas have committed to take to implement measures on an accelerated schedule to attain the 8-hour ozone standard by December 31, 2007. On April 5, 2004, these environmental organizations and EPA entered into a joint stipulation to modify the deadline in the consent decree. The parties agreed to extend the deadline for the effective date of designations with respect to each area which EPA determines meets the requirements of the Protocol and EPA guidance.

Comment: One commenter expressed concern about the health impact and the effect on air quality of delaying the effectiveness of nonattainment.

Response: The compact areas that are violating the standard are designated nonattainment (with deferred effective date), which means EPA is acknowledging the air quality problem of the area and the health impact on the community. However, these areas are committed to early reductions and early implementation of control measures that make sense for the local area. The Agency believes this proactive approach involving multiple, diverse stakeholders is beneficial to the citizens of the area by raising awareness of the need to adopt and implement measures that will reduce emissions and improve air quality. 2. Designations Process for Compact Areas

Comment: Several commenters expressed concern about EPA ’ s process for designating areas that are participating in a compact. In addition, a number of commenters also were confused about the following statement in the June 2, 2003 proposed 8-hour implementation rule: ‘‘ States are advised that if EPA determines that any portion of a compact area should become part of an 8-hour ozone nonattainment area, that portion would no longer be eligible for participation in the Early Action Compact, and the effective date of the nonattainment designation would not be deferred ’’ (68 FR 32860, June 2, 2003). Some of these commenters noted that the language, as written, could be interpreted to mean if any EAC area becomes designated as nonattainment for the 8-hour ozone standard, the EAC is no longer valid. A number of commenters submitted recommendations to EPA for either including or excluding certain participating EAC counties from the designated area.

Response: In determining the boundary for the designated area, we applied the same procedure as we did for areas that are not participating in an EAC, as described elsewhere in this document. The commenters are referring to language in section VIII.A.3 of the June 2, 2003 proposed rule for implementing the 8-hour ozone standard at 68 FR 32860. At the time we entered into compact agreements with the local communities by December 2002, and at the time we proposed the 8-hour implementation rule, we had not made a decision as to which participating counties would be included in a nonattainment area. Therefore, at that time we were not able to determine the appropriate boundary for the area that would be eligible for a deferral of the effective date of nonattainment designation. We agree with the commenters that the preamble language in the proposed 8-hour implementation rule is not clear. The language was intended to be applied to a portion of a compact area that is adjacent to or part of an area that is violating the 1-hour ozone standard (or otherwise did not qualify for participation in a compact), and subsequently is designated nonattainment for the 8-hour ozone standard.

An example is the Catawba EAC, which includes York County, SC, as well as Chester, Lancaster and Union Counties, SC. York County, which has one monitor that is attaining the 8-hourstandard, is in the Charlotte-GastoniaRock Hill MSA. We have examined all applicable air quality-related factors in our guidance and concluded that part of the county is contributing to a violation in the MSA. Based on our analysis, therefore, we are designating this county as a partial county nonattainment area, in the 8-hour ozone nonattainment area for Charlotte-Gastonia-Rock Hill. As we noted earlier, nonattainment is defined in the CAA as an area that is violating the NAAQS or is contributing to a nearby area that is violating the NAAQS. York County ranks high in population growth (25 percent) and the predicted growth from 2000 to 2010 is 12 percent, approximately 20,000 additional population. York County ranks second and third for VOC and NOX 

### emissions in the CMSA, and 94 percent of its population of workers drives to work within the CMSA. York County may continue in the Catawba compact along with the other three counties as a voluntary participant; however, the nonattainment portion of York County is not eligible for a deferred effective date. Moreover, because the other counties in the Charlotte-Gastonia-Rock Hill nonattainment area are not participating in the EAC process, the Charlotte area, which includes York County, is not eligible for a deferred effective date. In no way does EPA intend for the Catawba compact to be revoked. For EPA ’ s responses to comments regarding designation and boundary issues for specific EAC areas, see the RTC document and the TSD for this rulemaking.

Comment: A number of commenters recommended that EPA clarify exactly when a compact area would be designated nonattainment if it fails to meet a milestone.

Response: Today, we have determined that a number of compact areas have met the March 31, 2004 milestone (plan of local measures); therefore, the effective date of nonattainment designation for these areas is deferred until September 30, 2005. In Table 3 we have listed the air quality designations and the effective dates for all counties participating in EACs. In addition, today, we have determined that some compact areas have not met the March 31, 2004 milestone. A discussion of our assessment of these local plans is provided elsewhere in this document. We are designating these areas as nonattainment, which is effective June 15, 2004.

In another section of this document, we are promulgating regulatory text that clarifies the actions we would take in the event a compact area does not meet subsequent milestones. We have summarized those actions below.

If an EAC area fails to meet a milestone, in accordance with our guidance, we intend to take action as soon as practicable to remove the deferral, which would trigger the effective date of the nonattainment designation. If a State fails to submit a SIP revision for a compact area, consisting of the adopted local plan and the demonstration of attainment by December 31, 2004, we intend to take

### Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations 

## 23871 action as soon as practicable (e.g. , January 2005) to remove the deferral for that area, which would trigger the effective date of the nonattainment designation and, thus, also the classification, rather than letting the designation take effect automatically on September 30, 2005. The State would be required to submit a revised attainment demonstration within 1 year of the effective date of the nonattainment designation.

Assuming EPA takes rulemaking action to continue to defer the effective date of the nonattainment designation for compact areas, if a compact area fails the December 31, 2005 milestone (complete implementation of local measures), we would take action as soon as practicable (e.g. , by March 31, 2006) to remove the deferral which would trigger the effective date of their nonattainment designation and, thus, also their classification, rather than letting the designation take effect automatically at the next deferred date. The State would be required to submit a revised attainment demonstration within 1 year of the effective date of the nonattainment designation.

Similarly, for any area that does not meet the June 30, 2006 milestone (assessment of air quality improvement and emissions reductions from implementation of measures), we would take action as soon as practicable (e.g. , by September 30, 2006) to remove the deferral which would trigger the effective date of their nonattainment designation and, thus, also their classification. If the area, based on the most recent 3 years of quality-assured monitoring data, is not attaining the 8- hour ozone standard by December 31, 2007, we would take action by April 15, 2008, to remove the deferral which would trigger the effective date of their nonattainment designation and, where applicable, classification.

Comment: Some commenters strongly recommended that if the compact measures fail to be implemented or fail to achieve targeted emissions reductions, the compact area should immediately be designated as nonattainment with a subpart 2 classification and be required to comply with all applicable obligations within the original timeframe.

Response: In another section of this document, we are promulgating regulatory text that clarifies the actions we intend to take in the event a compact area does not meet subsequent milestones. Compact areas are designated as nonattainment and the effective date of that designation is deferred. The deferral for any areas that do not meet or fail any milestone will be removed as soon as practicable which would trigger the effective date of their nonattainment designation and, thus, also the classification consistent with the final 8-hour implementation rule. If called for by the area’ s classification, these areas will be required to submit a revised attainment demonstration within 1 year of the effective date of designation and will be subject to all applicable requirements of title I, part D of the CAA, to be implemented within a time frame consistent with the area’ s classification.

Comment: One commenter believes the second rolling deferred effective date is not necessary and should be eliminated. According to the commenter, there should be only two separate deferral dates promulgated for nonattainment designations for areas where controls would be implemented by September 30, 2005, and no other milestones (the June 2006 progress assessment) would be needed between implementation of controls and attainment.

Response: The June 2006 milestone, which is one of the compact requirements that would be subject to the second deferred effective date (December 31, 2006), provides that States report progress of EAC areas in implementing adopted measures and assess improvements in air quality and reductions in NOX 

### and VOC emissions. The second deferral is a checkpoint that is needed to ensure that areas are making progress toward attainment. This milestone can be one of the progress reports, but it is considered a milestone because EPA believes it is important to have a checkpoint between implementation of measures by December 2005 and attainment in December 2007.

Comment: A number of commenters were concerned about EPA ’ s statement in the proposal that the Agency would commit to not redesignate areas that subsequently violate the 8-hour ozone NAAQS to nonattainment, provided the area continues to meet all compact milestones and requirements.

Response: In the proposed rule at FR 68 70113, EPA did state its intention to commit to not redesignate EAC areas to nonattainment that are designated attainment in April 2004. We realize that our shorthand phrasing did not properly convey our intent. To clarify, in deciding whether to redesignate an EAC area to nonattainment, EPA will consider the factors in section 107(d)(3)(a) of the CAA. If an EAC area continues to meet its compact milestones, EPA believes those factors should weigh in favor of not redesignating the area to nonattainment immediately, but rather waiting to see if the programs the area puts in place will bring it back into attainment. 3. Transportation/Fuels-Related Comments

Comment: The EPA received a number of comments expressing concern that lack of transportation conformity in EAC areas will negatively impact air quality in these areas. In addition, several commented that since EAC areas are not eligible to receive Congestion Mitigation and Air Quality Improvement Program (CMAQ) funding, projects to reduce congestion and, thereby, reduce mobile source emissions, would not occur. Another commenter suggested that EPA work with the U.S. Department of Transportation (DOT) to revise the TEA – 21 so that EAC areas are eligible to receive CMAQ funding.

Response: The commenters are correct that EAC areas violating the 8-hour ozone standard, which would otherwise have a nonattainment date effective June 1, 2004, will not be subject to transportation or general conformity requirements for the 8-hour standard in 2005. The EAC protocol does not require EAC areas to meet CAA transportation conformity requirements, since, as noted, these requirements apply one year after the 8-hour nonattainment designation becomes effective.

However, continuing to defer 8-hour conformity requirements is contingent upon the area’ s ability to demonstrate adherence to the compact. Consistent with 40 CFR 93.102(d) and CAA section 176(c)(6), conformity for the 8-hour ozone standard will not apply, provided the area meets all of the terms and milestones of its compact between 2004 and 2007. At any point, if a milestone is missed, the nonattainment designation becomes effective and conformity for the 8-hour standard will be required one year after the effective date of EPA ’ s nonattainment designation.

The EAC areas that are maintenance areas for the 1-hour standard will be subject to conformity until 1 year after the effective date of designation of the 8-hour standard. At that time the 1-hour standard will be revoked. Thus, for an EAC area that meets all of its milestones and whose deferral is lifted in April 2008, the 8-hour attainment designation would become effective in April 2008, and the 1-hour standard would be revoked 1 year later or, April 2009. For an EAC area that is also a 1-hour maintenance area under § 175A, the area would be subject to both its 1-hour maintenance plan and 1-hour

## 23872 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations transportation conformity until April 2009.

Finally, EPA would like to clarify that transportation conformity is not a control measure similar to voluntary control programs funded through CMAQ dollars. Rather, it establishes a process for state and local governments to consider the broader emissions impacts of planned highway and transit activities to ensure that Federal funding and approval goes to those transportation activities that are consistent with air quality goals.

Comment: One commenter stated that they were reluctant to enter into a compact agreement knowing that they would not receive CMAQ funds. Several commenters also suggested that EPA provide EAC areas with tangible financial incentives to proactively improve their air quality, as well as work with the DOT to revise the Transportation Efficiency Act (TEA) so that it allows EAC areas to receive CMAQ funding.

Response: The commenters are correct that EAC areas are not eligible to receive CMAQ funding under current law. The CMAQ apportionment formula in TEA – 21 contains no provisions to allow inclusion of EAC areas into the formula and thus into the authorized CMAQ levels for each state. Thus, until and unless the 8-hour ozone nonattainment designation is effective, areas cannot be eligible for CMAQ funding, absent a change in the law.

The primary incentive for many areas entering into an EAC is deferral of a nonattainment designation and major requirements, such as transportation conformity and NSR. It is true that compact areas are subject to SIP requirements, but not to other such major requirements. The EPA ’ s interpretation is that Congress intended to link the obligations that come with a nonattainment designation to CMAQ funding. The purpose of the CMAQ program is to help those areas burdened with the significant obligations of the CAA attain the NAAQS as expeditiously as possible. Under the current CMAQ program, an EAC area would not be able to receive CMAQ funds because it would not be designated as a nonattainment or maintenance area.

Since TEA – 21 has not been reauthorized as of this writing, EPA cannot postulate on whether it will contain a new provision allowing compact areas to receive CMAQ funding. The reauthorization bills passed by the Senate and House contain no such provision.

Comment: A number of EAC areas are considering the addition of cetane additives to fuel for increased fuel efficiency. Several commenters expressed concern about the focus on diesel cetane. They have expressed these concerns in detail in earlier correspondence with both the Agency and the Ozone Transport Commission.

Response: Clean fuel programs have been an integral part of the nation ’ s strategy to reduce smog-forming emissions and other harmful pollutants, including air toxics from our nation ’ s air. For example, the Federal reformulated gasoline program (RFG) and lower volatility fuels have been cost effective and have provided significant and immediate reductions in air pollution levels throughout the nation.

The CAA also allows States, under specified circumstances, to design and implement their own clean fuel programs. Several EAC areas are considering such programs including cetane improvement programs. Cetane improvement programs have the potential to contribute emission reductions needed for progress toward attainment and maintenance of the NAAQS. (See EPA Technical Report entitled, ‘‘ The Effect of Cetane Number Increase Due to Additives on NOX 

### Emissions from Heavy-Duty Highway Engines ’’ , EPA – 420 – R– 03 – 002, February 2003. This document can be downloaded from: http://www.epa.gov/ otaq/models/analysis.htm. The EPA is now in the process of developing guidance to help States properly quantify the benefits of cetane improvement programs for their areas.

In selecting possible clean fuel programs and other potential ozone control measures, states will engage in a careful and extensive process. It is during this process that States should properly consider and evaluate their air quality needs, the air quality benefits of specific measures, costs, ease of implementation, enforceability and other issues and factors like those the commenter raises with respect to cetane programs. In addition, the States must involve the public in the selection of control measures, through hearings and opportunities to comment. 4. Regulatory Text

Comment: Several commenters strongly recommended that EPA include regulatory text in the final rule. One commenter, in particular, suggested that EPA do the following: 1. Codify the rolling deferred effective date so that it is enforceable and that areas are held accountable if they miss a milestone;

2. include in the final rule all deadlines and milestones specified in our EAC guidance; 3. codify the September 30, 2005 deadline for EPA action to approve/ disapprove SIP submittals;

4. codify the December 31, 2008 deadline for States to submit a revised attainment demonstration SIP for EAC areas that fail to attain by December 31, 2007.

Response: Based on the recommendations of several commenters, we have added regulatory text to the final rule. This language codifies the EAC program into part 81 of the CFR. In addition, the regulatory text clarifies what is required of compact areas and the consequences to these areas if they do not meet a milestone. X. How Do Designations Affect Indian Country?

All counties, partial counties or Air Quality Control Regions listed in the table at the end of this document are designated as indicated, and include Indian country geographically located within such areas, except as otherwise indicated.

As mentioned earlier in this document, EPA ’ s guidance for determining nonattainment area boundaries presumes that the larger of the 1-hour nonattainment area, CMSA or MSA with a violating monitor forms the bounds of the nonattainment area but that the size of the area can be larger or smaller depending on contribution to the violation from nearby areas and other air quality-related technical factors. In general, and consistent with relevant air quality information, EPA intends to include Indian country encompassed within these areas as within the boundaries of the area for designation purposes to best protect public health and welfare. The EPA anticipates that in most cases relevant air quality information will indicate that areas of Indian country located within CMSAs or MSAs should have the same designation as the surrounding area. However, based on the factors outlined in our guidance, there may be instances where a different designation is appropriate.

A state recommendation for a designation of an area that surrounds Indian country does not dictate the designation for Indian county. However, the conditions that support a State’ s designation recommendation, such as air quality data and the location of sources, may indicate the likelihood that similar conditions exist for the Indian county located in that area. States generally have neither the responsibility nor the authority for planning and regulatory activities under the CAA in Indian country.

### Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations 

## 23873 XI. Statutory and Executive Order Reviews

Upon promulgation of a new or revised NAAQS, the CAA requires EPA to designate areas as attaining or not attaining that NAAQS. The CAA then specifies requirements for areas based on whether such areas are attaining or not attaining the NAAQS. In this final rule, we assign designations to areas as required. We also indicate the classifications that apply as a matter of law for areas designated nonattainment. This rule also provides flexibility for areas that have entered into a compact and take early action to achieve emissions reductions necessary to attain the 8-hour ozone standard. This action defers the effective date of the nonattainment designation for these areas and establishes regulations governing future actions with respect to these areas. A. Executive Order 12866: Regulatory Planning and Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), the Agency must determine whether the regulatory action is ‘‘ significant’’ and, therefore, subject to OMB review and the requirements of the Executive Order. The Order defines ‘‘ significant regulatory action ’’ as one that is likely to result in a rule that may:

(1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or Tribal governments or communities;

(2) create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

(3) materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or

(4) raise novel legal or policy issues arising out of legal mandates, the President’ s priorities, or the principles set forth in the Executive Order.

Pursuant to the terms of Executive Order 12866, it has been determined that this rule is not a ‘‘ significant regulatory action ’’ because none of the above factors applies. As such, this final rule was not formally submitted to OMB for review. B. Paperwork Reduction Act

This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. This rule responds to the requirement to promulgate air quality designations after promulgation of a NAAQS. This requirement is prescribed in the CAA section 107 of Title 1. The present final rule does not establish any new information collection burden apart from that required by law. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. 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 EPA ’ s regulations in 40 CFR are listed in 40 CFR part 9. C. Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedures Act or any other statute unless the agency certifies the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions. For purposes of assessing the impacts of today ’ s final rule on small entities, small entity is defined as: (1) A small business that is a small industrial entity as defined in the U.S. Small Business Administration (SBA) size standards. (See 13 CFR 121.); (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3)a small organization that is any not-forprofit enterprise which is independently owned and operated and is not dominant in its field.

The portion of this rule designating areas for the 8-hour ozone NAAQS indicating the classification for each subpart 2 area designated nonattainment, is not subject to the RFA because it was not subject to notice and comment rulemaking requirements. See CAA section 107(d)(2)(B). This rule also defers the effective date of the nonattainment designation for areas that implement control measures and achieve emissions reductions earlier than otherwise required by the CAA in order to attain the 8-hour ozone NAAQS. The deferral of the effective date will not impose any requirements on small entities. States and local areas that have entered into compacts with EPA have the flexibility to decide which sources to regulate in their communities.

After considering the economic impacts of today ’ s final rule on small entities, I certify that this rule will not have a significant economic impact on a substantial number of small entities. D. Unfunded Mandates Reform Act

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104 – 4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and Tribal governments and the private sector. Under section 202 of the UMRA, EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with ‘‘ Federal mandates ’’ that may result in expenditures to State, local, and Tribal governments, in the aggregate, or to the private sector, of $100 million or more in any one year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most cost-effective or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including Tribal governments, it must have developed under section 203 of the UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and

## 23874 Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations informing, educating, and advising small governments on compliance with the regulatory requirements.

Today ’ s final action does not include a Federal mandate within the meaning of UMRA that may result in expenditures of $100 million or more in any one year by either State, local, or Tribal governments in the aggregate or to the private sector, and therefore, is not subject to the requirements of sections 202 and 205 of the UMRA. It does not create any additional requirements beyond those of the 8-hour National Ambient Air Quality Standards (NAAQS) for Ozone (62 FR 38894; July 18, 1997), therefore, no UMRA analysis is needed. This rule establishes the application of the 8-hour ozone standard and the designation for each area of the country for the 8-hour NAAQS for Ozone. The CAA requires States to develop plans, including control measures, based on their designations and classifications. In this rule, EPA is also deferring the effective date of nonattainment designations for certain areas that have entered into compacts with us and is promulgating regulations governing future actions with respect to these areas.

One mandate that may apply as a consequence of this action to all designated nonattainment areas is the requirement under CAA section 176(c) and associated regulations to demonstrate conformity of Federal actions to SIPs. These rules apply to Federal agencies and Metropolitan Planning Organizations (MPOs) making conformity determinations. The EPA concludes that such conformity determinations will not cost $100 million or more in the aggregate.

The EPA believes that any new controls imposed as a result of this action will not cost in the aggregate $100 million or more annually. Thus, this Federal action will not impose mandates that will require expenditures of $100 million or more in the aggregate in any one year.

Nonetheless, EPA carried out consultations with governmental entities affected by this rule, including States, Tribal governments, and local air pollution control agencies. E. Executive Order 13132: Federalism

Executive Order 13132, entitled ‘‘ Federalism’’ (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure ‘‘ meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications. ’’ ‘‘ Policies that have federalism implications ’’ is defined in the Executive Order to include regulations that 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. ’’

This final rule does not have federalism implications. It will 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. The CAA establishes the scheme whereby States take the lead in developing plans to meet the NAAQS. This rule will not modify the relationship of the States and EPA for purposes of developing programs to implement the NAAQS. Thus, Executive Order 13132 does not apply to this rule.

Although Executive Order 13132 does not apply to this rule, EPA discussed the designation process and compact program with representatives of State and local air pollution control agencies, and Tribal governments, as well as the Clean Air Act Advisory Committee, which is also composed of State and local representatives. In the spirit of Executive Order 13132, and consistent with EPA policy to promote communications between EPA and State and local governments, EPA specifically solicited comment on the proposed rule for deferring the effective date of nonattainment designations from State and local officials. The portion of this rule that assigns designations is not subject to notice and comment under section 107(d)(2)(B) of the CAA and, therefore, no proposed rulemaking was prepared which specifically solicited comment on the designations. However, section 107(d)(1)(A) establishes a process whereby States first recommends the designations for areas in their States. In addition, the Agency has consulted extensively with representatives of State, Tribal and local governments, including elected officials regarding the designations. The EPA also notified national organizations of State and local officials and made EPA staff available to discuss the action with the organization staff and their members. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

Executive Order 13175, entitled ‘‘ Consultation and Coordination with Indian Tribal Governments ’’ (65 FR 67249, November 9, 2000), requires EPA to develop an accountable process to ensure ‘‘ meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications. ’’ This final rule does not have ‘‘ Tribal implications ’’ as specified in Executive Order 13175. This rule concerns the classification and designation of areas as attainment or nonattainment of areas for the 8-hour ozone standard and deferral of the effective date of the nonattainment designation for areas participating in the early action compact process and that have met all milestones. The CAA provides for States to develop plans to regulate emissions of air pollutants within their jurisdictions. The TAR gives Tribes the opportunity to develop and implement CAA programs such as programs to attain and maintain the 8- hour ozone NAAQS, but it leaves to the discretion of the Tribe whether to develop these programs and which programs, or appropriate elements of a program, they will adopt. Early Action Compact areas that would be affected by this final rule would be required to develop and submit local plans for adoption and implementation of the 8- hour ozone standard earlier than the CAA requires. These plans would be submitted to EPA as SIP revisions in December 2004. No early action compact areas include Tribal land.

This final rule does not have Tribal implications as defined by Executive Order 13175. It does not have a substantial direct effect on one or more Indian Tribes, since no Tribe has implemented a CAA program to attain the 8-hour ozone NAAQS at this time or has participated in a compact. Furthermore, this rule does not affect the relationship or distribution of power and responsibilities between the Federal government and Indian Tribes. The CAA and the TAR establish the relationship of the Federal government and Tribes in developing plans to attain the NAAQS, and this rule does nothing to modify that relationship. Because this rule does not have Tribal implications, Executive Order 13175 does not apply.

Although Executive Order 13175 does not apply to this rule, EPA did outreach to Tribal representatives regarding the designations and to inform them about the compact program and its impact on designations. The EPA supports a national ‘‘ Tribal Designations and Implementation Work Group ’’ which provides an open forum for all Tribes to voice concerns to EPA about the designation and implementation process for the NAAQS, including the 8-hour ozone standard. These discussions informed EPA about key Tribal concerns regarding designations as the rule was under development.

### Federal Register / Vol. 69, No. 84 / Friday, April 30, 2004 / Rules and Regulations 

## 23875 G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

Executive Order 13045: ‘‘ Protection of Children From Environmental Health and Safety Risks ’’ (62 FR 19885, April 23, 1997) applies to any rule that (1) is determined to be ‘‘ economically significant’’ as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have disproportionate effect on children. If the regulatory action meets both criteria, the Agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency.

The final rule is not subject to Executive Order 13045 because it is not economically significant as defined in E.O. 12866, and because the Agency does not have reason to believe the environmental health risks or safety risks addressed by this rule present a disproportionate risk to children. Nonetheless, we have evaluated the environmental health or safety effects of the 8-hour ozone NAAQS on children. The results of this risk assessment are contained the National Ambient Air Quality Standards for Ozone, Final Rule (62 FR 38855
– 38896; specifically, 62 FR 38854, 62 FR 38860 and 62 FR 38865). H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use

This rule is not subject to Executive Order 13211, ‘‘ Actions That Significantly Affect Energy Supply, Distribution, or Use, ’’ (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866.

Information on the methodology and data regarding the assessment of potential energy impacts is found in Chapter 6 of U.S. EPA 2002, Cost, Emission Reduction, Energy, and Economic Impact Assessment of the Proposed Rule Establishing the Implementation Framework for the 8- Hour, 0.08 ppm Ozone National Ambient Air Quality Standard, prepared by the Innovative Strategies and Economics Group, Office of Air Quality Planning and Standards, Research Triangle Park, NC April 24, 2003. I. National Technology Transfer Advancement Act

Section 12(d) of the National Technology Transfer Advancement Act of 1995 (NTTAA), Public Law No. 104 – 113, section 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards (VCS) in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g. , materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable VCS.

This action does not involve technical standards. Therefore, EPA did not consider the use of any VCS. J. Congressional Review Act

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. The EPA will submit a report containing this rule 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). This rule will be effective June 15, 2004. K. Judicial Review

Section 307(b)(1) of the CAA indicates which Federal Courts of Appeal have venue for petitions of review of final actions by EPA. This Section provides, in part, that petitions for review must be filed in the Court of Appeals for the District of Columbia Circuit (i) when the agency action consists of ‘‘ nationally applicable regulations promulgated, or final actions taken, by the Administrator, ’’ or (ii) when such action is locally or regionally applicable, if ‘‘ such action is based on a determination of nationwide scope or effect and if in taking such action the Administrator finds and publishes that such action is based on such a determination. ’’

This rule designating areas for the 8- hour ozone standard is ‘‘ nationally applicable’’ within the meaning of section 307(b)(1). This rule establishes designations for all areas of the United States for the 8-hour ozone NAAQS. At the core of this rulemaking is EPA ’ s interpretation of the definition of nonattainment under section 107(d)(1) of the Clean Air Act. In determining which areas should be designated nonattainment (or conversely, should be designated unclassifiable/attainment), EPA used a set of 11 factors that it applied consistently across the United States.

For the same reasons, the Administrator also is determining that the final designations are of nationwide scope and effect for purposes of section 307(b)(1). This is particularly appropriate because in the report on the 1977 Amendments that revised section 307(b)(1) of the CAA, Congress noted that the Administrator’ s determination that an action is of ‘‘ nationwide scope or effect’’ would be appropriate for any action that has ‘‘ scope or effect beyond a single judicial circuit. ’’ H.R. Rep. No. 95

– 294 at 323, 324, reprinted in 1977 U.S.C.C.A.N. 1402 – 03. Here, the scope and effect of this rulemaking extend to numerous judicial circuits since the designations apply to all areas of the country. In these circumstances, section 307(b)(1) and its legislative history calls for the Administrator to find the rule to be of ‘‘ nationwide scope or effect’’ and for venue to be in the D.C. Circuit.

Thus, any petitions for review of final designations must be filed in the Court of Appeals for the District of Columbia Circuit within 60 days from the date final action is published in the Federal Register . List of Subjects in 40 CFR Part 81
