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 redesignated 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 Clean Air Act Amendments of 1990, Kentucky’s 

request to amend the State Implementation Plan (SIP) is based on the most recent three years of 

monitoring data showing no additional violations of 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 in ozone 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).

BACKGROUND 

The Clean Air Act Amendments of 1990 (CAA) establishes a process for air quality management 

through the NAAQS. Area designations are required after promulgation 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. Court 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 designate areas for any new or revised NAAQS in 

accordance with the CAA. 

In February 2001, the U.S. Supreme Court upheld U.S. EPA authority to set the NAAQS and 

remanded the case back to the D.C. Circuit for disposition of issues the D.C. Circuit did not 

address in its initial decision. 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 Transportation Equity Act for the 21st 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 restricted the agency’s authority to 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 Section 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 based 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 in the Kentucky portion of the nonattainment 

area; the nonattainment portion of Butler, Clermont, Clinton, Hamilton and Warren counties in 

Ohio; and a portion of Dearborn County, 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-hour nonattainment area is 

included in Appendix C. Dearborn County, Indiana does not have a monitoring station.

The data collected by Kentucky was quality assured 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 projected 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 season 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 Agricultural 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. 

FEDERAL CONTROL MEASURES

TIER 2 VEHICLE STANDARDS 

On February 10, 2000, U.S. EPA finalized a federal rule (65 FR 6698) to significantly 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 be phased in between 2004 and 2009. U.S. EPA has 

estimated that NOx 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 to 30 ppm starting in 

January of 2006. Most gasoline sold in Kentucky prior to January 2006 had a sulfur content of 
7 

approximately 300 ppm. Sulfur occurs naturally in gasoline, but interferes with 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. 

HEAVY-DUTY GASOLINE AND DIESEL HIGHWAY VEHICLES STANDARDS

New U.S. EPA standards promulgated October 6, 2000, (65 FR 59896) to reduce NOx and VOC 

emissions from heavy-duty gasoline and diesel highway vehicles began to take effect in 2004. A 

second phase of standards and testing procedures, which began in 2007, began reducing 

particulate matter from heavy-duty highway engines, and reduces highway 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. 

LARGE NONROAD DIESEL ENGINES RULE

On May 11, 2004, the U.S. EPA promulgated new rules (69 FR 26222) for large nonroad diesel 

engines, such as those used in construction, 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 to 500 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 engines using higher-content sulfur diesel. 
8 

NONROAD SPARK-IGNITION ENGINES AND RECREATIONAL ENGINES STANDARD

On November 8, 2002, the U.S. EPA promulgated new rules (67 FR 68242) 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 large spark-ignition engines (forklifts and airport 

ground service equipment), recreational vehicles (off-highway motorcycles and all-terrainvehicles), and recreational marine diesel engines. The regulation varies based upon the type of 

engine or vehicle. 

The large spark-ignition engines contribute to ozone formation and ambient CO and PM levels in 

urban areas. Tier 1 of this standard was implemented in 2004 while Tier 2 began in 2007. Like 

the large spark-ignition, recreational vehicles contribute to ozone formation 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 kilowatts are 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. 
9 

NOX SIP CALL IN SURROUNDING STATES

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 develop rules to meet their 

budget. A trading program of NOx emissions was established, allowing sources to buy credits to 

meet their NOx budget as opposed to actually installing controls. The emission budgets were to 

be met by May of 2004. Even with the trading program, the amount of ozone season NOx 

emissions have decreased significantly 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 emissions of SO2 and PM 

in conjunction with the toxic air pollutant reductions. The applied Maximum Achievable Control 

Technology (MACT) control efficiencies were 4 percent for SO2 and 40 percent for PM10 and 

PM2.5. The USEPA’s industrial boiler MACT rules 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 
10 

USEPA will have re-promulgated a boiler MACT rule or states will have addressed the issue 

through state rule making. 

Combustion Turbine MACT. The projection inventories do not include 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. 

STATE CONTROL MEASURES 

Kentucky has adopted a number of regulations and legislation to address pollution issues across 

the State. These include the NOx SIP Call and the Open Burning Rules. These regulations are 

summarized below. 

NOX SIP CALL RULE

In response to the U.S. EPA’s NOx SIP call, Kentucky developed and adopted Regulations 401 

KAR 51:150, 401 KAR 51:160, 401 KAR 51:170, 401 KAR 51:180, 401 KAR 51:190, and 401 

KAR 51:195 to control the emissions of NOx from EGUs and large stationary combustion 

sources. These rules cover (1) fossil fuel-fired stationary boilers, combustion turbines, and 

combined cycle systems serving a generator with a nameplate capacity greater than 25 

megawatts and selling any amount of electricity, (2) fossil fuel-fired stationary boilers, 
11 

combustion turbines, and combined cycle systems having a maximum design heat input greater 

than 250 million British thermal units per hour, and (3) reciprocating stationary internal 

combustion engines rated at equal or greater than 2400 brake horsepower (3000 brake 

horsepower for diesel engines and 4400 brake horsepower for dual fuel engines). As part of the 

NOx SIP call, the U.S. EPA rules established a NOx budget for sources in Kentucky and other 

states. 

Kentucky’s NOx SIP Call rule was predicted to reduce summertime NOx emissions 66% from 

power plants and other industries statewide by 2006. 

OPEN BURNING BANS

Kentucky revised the open burning regulation, 401 KAR 63:005, to prohibit most types of open 

burning in moderate ozone nonattainment areas within Kentucky during the period of MaySeptember . This requirement continues in the Kentucky portions of the Cincinnati-Hamilton 8-

hour ozone nonattainment area counties of Boone, Campbell, and Kenton. 

CLEAN AIR INTERSTATE RULE

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 SO2: 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 SO2

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 standard. 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 an area 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 10 years 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 become effective should the area fail to continue to 

maintain the 8-hour ozone standard. 
13 

EMISSION PROJECTION METHODOLOGY

One of the planning elements listed in the memorandum dated September 4, 1992, (Appendix A) 

required for attainment redesignation purposes is developing a projection 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. Documentation 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 projected emissions 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 projection inventories for VOC and NOx emissions for the 

attainment year 2008, and years 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 year. Even though the VOC emissions increase in 

Boone County from 2005 to 2008, the overall VOC emissions decrease.

The emissions inventory is broken down into four components: point, area, highway mobile, and 

non-highway mobile sources. Using 2008 as the attainment year, the subsequent years were 

chosen at appropriate intervals and project maintenance for at least 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. 

POINT SOURCES

For this inventory purpose, point sources are defined 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 information has been uploaded into the 

U.S. EPA National Emissions Inventory (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 corresponding 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. 
18 

MOBILE 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 performed can be found in Appendix E, including input and output files for 

those projections. 

AREA SOURCES/NON-HIGHWAY MOBILE SOURCES

As previously stated above, the emissions and projections for area and nonhighway mobile 

sources were provided by LADCO. A more thorough discussion 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, Programs, 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.

For 2015, the safety margin added to the mobile VOC emissions is 2 tpd, and the safety margin 

added to the mobile NOx emissions is 3 tpd. For 2020, the safety margin added to the mobile 

VOC emissions is 3 tpd, and the safety margin added to the mobile NOx emissions is 5 tpd as 

seen below in Table 15.

The addition of the safety margin to the 2015 and 2020 mobile emissions must ensure that the 

total emissions from all sectors do not exceed the emissions in the attainment year 2008. The 

safety margin amounts added to not cause the projected emissions in 2015 and 2020 to exceed 

the emissions for the year 2008. 

The mobile budgets included in Table 15 above will apply to future transportation conformity 

determinations. 
23 

TOTAL OF ALL EMISSIONS

It is important to recognize the differences between the 2008 tpd for each pollutant and the 

projected tpd for each pollutant for the year 2020. Tables 16 and 17, and Graphs 1 and 2 show 

that for the combined area, projected 2020 emissions for all pollutants are less than 2008 

attainment year levels.

As shown in table 18, VOC emissions in the nonattainment area are projected to decrease by 

41.71 tons/day. Cleaner vehicles and fuels are expected to be in place in 2009 and 2018 and they 

cause an overall drop in VOC emissions. 
25 

NOx 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 to maintain 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 in Kentucky are subject to RACT; 

• All major modifications to existing major VOC sources are subject to RACT 

requirements; 

• Implementation of a program to enhance inspection of stationary sources 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 reductions will 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 discussed above, the existing ozone monitoring network 

located within the Kentucky counties of the Cincinnati-Hamilton Basic 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 ozone season, 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 after 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 reconstructions 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 deemed more 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 Development District. A copy of 

the public hearing notice and a copy of the advertisements 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.

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. 
3

 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 4

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 1795

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 required SIP 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

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;

and submit 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.
Attachment B

The EPA policies for implementing section 107 of the Act for

redesignations are contained in the following memorandums.

1. "Procedures for Processing Requests to Redesignate Areas

to Attainment," John Calcagni, Director, Air Quality Management

Division, September 4, 1992.

2. "State Implementation Plan (SIP) Actions Submitted in

Response to Clean Air Act (CAA) Deadlines," John Calcagni,

Director, Air Quality Management Division, October 28, 1992.

3. "Contingency Measures for Ozone and Carbon Monoxide (CO)

Redesignations," G. T. Helms, Chief, Ozone/Carbon Monoxide

Programs Branch, June 1, 1992.

4. "Maintenance Plans for Redesignation of Ozone and Carbon

Monoxide Nonattainment Areas," G. T. Helms, Chief, Ozone/Carbon

Monoxide Programs Branch, April 30, 1992.

In the event that EPA does not approve the redesignation,

the applicable I/M program requirements and guidance can be found 

in 57 FR 52950, November 5, 1992 and in 40 CFR part 51. The

applicable VMT forecast guidance is described in the document

entitled, "Section 187 VMT Forecasting and Tracking Guidance,"

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.

II. What Is the Purpose of This 

Document? 

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. 

More detailed information on the 

health effects of ozone can be found at 

the following Web site: http:// 

www.epa.gov/ttn/naaqs/standards/ 

ozone/s_o3_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 

1 CAA 107(d)(1); TEA–21 § 6103(a). 

2 Memorandum of March 28, 2002, from John S. 

Seitz, ‘‘Boundary Guidance on Air Quality 

Designations for the 8-Hour Ozone National 

Ambient Air Quality Standards.’’ 

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 or 

smaller, 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

for the Implementation of Title I of the CAA 

Amendments of 1990; Proposed Rule.’’ April 16, 

1992 (57 FR 13498 at 13501 and 13510). 

7 For the 1-hour ozone NAAQS, design value is 

defined at 40 CFR 51.900(c). For the 8-hour ozone 

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.

*But not including. 

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 

Moderate 

Portland, 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_measures_full_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.

2 The part of York County, SC that includes the portion within the Metropolitan Planning Organization (MPO) is designated nonattainment and

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/

to Achieve and Maintain the 8-hour Ozone 

Standard’’, Texas Commission on Environmental 

Quality (TCEQ), March 2002 (Protocol). 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 for 

regulatory 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-hour 

standard, 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.

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

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.
