§81.300 Scope.
(a) Attainment status designations as approved or designated by the Environmental Protection Agency (EPA) pursuant to section 107 of the CAA are listed in this subpart. Area designations are subject to revision whenever sufficient data become available to warrant a redesignation. Both the state and EPA can initiate changes to these designations, but any state redesignation request must be submitted to EPA for concurrence. The EPA has replaced the national ambient air quality standards for particulate matter measured as total suspended particulate with standards measured as particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10). Accordingly, area designations for PM-10 are included in the lists in subpart C of this part. However, the TSP area designations will also remain in effect until the Administrator determines that the designations are no longer necessary for implementing the maximum allowable increases in concentrations of particulate matter pursuant to section 163(b) of the CAA, as explained in paragraph (b) of this section. The EPA has also added national ambient air quality standards for fine particulate matter measured as particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM2.5). Accordingly, area designations for PM2.5 are included in the lists in subpart C of this part.
(b) Designated areas which are listed below as attainment (“Better than national standards”) or unclassifiable (“Cannot be classified”) for total suspended particulate (TSP), sulfur dioxide (SO2), and nitrogen dioxide (NO2), represent potential baseline areas or portions of baseline areas which are used in determining compliance with maximum allowable increases (increments) in concentrations of the respective pollutants for the prevention of significant deterioration of air quality (PSD). With respect to areas identified as “Rest of State” it should be assumed that such reference comprises a single area designation for PSD baseline area purposes. However, for PM-10, the use of the term “Rest of State” is an interim measure to designate as unclassifiable all locations not originally designated nonattainment for PM-10 in accordance with section 107(d)(4)(B) of the Act.
(c) For PM-10 areas designated nonattainment, pursuant to section 107(d)(4)(b) by operation of law upon enactment of the 1990 Amendments to the Act, the boundaries are more fully described as follows:
(1) For cities and towns, the boundary of the nonattainment area is defined by the municipal boundary limits as of November 15, 1990, the date the 1990 Amendments were signed into law, except for areas which were formerly categorized as “Group I areas”, in which case the nonattainment area is defined by the municipal boundary limits as of October 31, 1990.
(2) Similarly, for planning areas, air quality maintenance areas, air basins, and urban growth boundaries the nonattainment area is defined by the entire planning area, air quality maintenance area, air basin, or urban growth boundary as of November 15, 1990, except for areas which were formerly “Group I”, in which case the boundary is defined by the entire planning area, air quality maintenance area, air basin, or urban growth boundary as of October 31, 1990. The foregoing is true except to the extent the planning area, air quality maintenance area, air basin, or urban growth boundary is further defined, e.g., by township, range and/or section. Such geographical descriptors remain a fixed part of the nonattainment boundaries irrespective of whether they are included in the planning area, air quality maintenance area, air basin, or urban growth boundary.
(3) The boundaries of PM-10 areas subsequently redesignated pursuant to section 107(d)(3) of the Act will be defined by the city, town, planning area, air quality maintenance area, air basin, or urban growth boundary in effect the date the designation is promulgated.
(d) For ozone and carbon monoxide (CO) areas the effective date(s) of air quality area designations and classifications are described as follows:
(1) For the portions of ozone and CO nonattainment areas that were designated nonattainment prior to the date of enactment of the Clean Air Act Amendments of 1990 (preenactment), the effective date is November 15, 1990.
(2) For the portions of nonattainment areas that were designated attainment prior to November 15, 1990, and included as part of an area designated nonattainment prior to November 15, 1990, the effective date of the designation to nonattainment is November 15, 1990 for:
(i) Purposes of determining whether the portion of the nonattainment area is eligible for the 5-percent classification adjustment under section 181(a)(4) (ozone) or section 186(a)(3) (CO);
(ii) Triggering the process for determining the C/MSA boundary adjustment under section 107(d)(4)(A)(iv)-(v);
(iii) Determining the scope of a “covered area” under section 211 (k)(10)(D) and opt-in under section 211 (k)(6) for the reformulated gasoline requirement and for purposes of determining the baseline of the reductions needed to meet the requirement to reduce volatile organic compounds by 15 percent under section 181 (b)(1). For all other purposes the effective designation date is January 6, 1992 (except for the Towns of Blooming Grove, Chester, Highlands, Monroe, Tuxedo, Warwick, and Woodbury in Orange County, NY, and for Putnam County, NY, for which the effective date is January 15, 1992, and for the remainder of Orange County, NY, for which the effective date is April 21, 1994).
(3) For nonattainment areas designated attainment preenactment, and not included as part of any nonattainment area that was designated nonattainment preenactment, the effective date for all purposes is the date of the designation.
(e) Provisions for Early Action Compact Areas with Deferred Effective Date of Nonattainment Designation.
(1) Definitions. The following definitions apply for purposes of this subpart. Any term not defined herein shall have the meaning as defined in 40 CFR 51.100 and §81.1
(i) Early Action Compact. The term “early action compact” (“compact”) means an agreement entered into on or before December 31, 2002, by -
(A) The Administrator;
(B) A State;
(C) An official of a county, parish, or town that -
(1) Is designated attainment for the 1-hour national ambient air quality standard for ozone;
(2) Has monitored data representing the most recent 3 years of quality-assured data that meets the 1-hour national ambient air quality standard for ozone; and
(3) May or may not be meeting the 8-hour national ambient air quality standard for ozone.
(ii) State. The term “State” has the meaning given the term in section 302 of the Clean Air Act (42 U.S.C. 7602).
(iii) Area. The term “area” means one or more counties, parishes, or towns that are participating in an early action compact.
(iv) State Implementation Plan. The term “State implementation plan” (“SIP”) means a plan required to be submitted to the Administrator by a State under section 110 of the Clean Air Act (42 U.S.C. 7410).
(v) 8-hour National Ambient Air Quality Standard means the air quality standards under the Clean Air Act (42 U.S.C. 7401 et seq.) codified at 40 CFR 50.10.
(2) What Are Early Action Compact Areas Required To Do? (i) Not later than June 16, 2003, the local area shall -

| The Telluride attainment/maintenance area begins at the intersection of Colorado State Highway 145 and the Telluride service area boundary, as it existed in 1991. The western edge of the nonattainment area until it meets Remine Creek is defined as follows: A tract of land located in a portion of the west one-half of Section 28 and the east one-half of Section 29, Township 43 North, Range 9 west, of New Mexico Principal Meridian, County of San Miguel, State of Colorado, described as follows: Beginning at the southwest corner of the said Section 28; Thence N 89 deg.36′00″ W. 292.70 Feet; Thence S 04 deg.05′12″ W. 538.63 Feet; Thence N 03 deg.29′42″ W. 780.19 Feet; Thence N 22 deg.15′00″ E. 3344.16 Feet; Thence S 51 deg.51′49″ E. 570.44 Feet; Thence S 03 deg.15′36″ E. 1106.22 Feet; Thence S 45 deg.24′42″ E. 546.96 Feet; Thence S 28 deg.41′12″ W. 549.62 Feet; Thence S 29 deg.40′09″ E. 169.68 Feet; Thence S 44 deg.30′03″ W. 649.51 Feet; Thence S 85 deg.54′00″ E. 660.00 Feet; Thence S 04 deg.06′00″ W. 660.00 Feet; Thence N 89 deg.56′00″ E. 1318.68 Feet; to the true point of beginning containing 11249 acres as described above. Then, at Remine Creek, the attainment/maintenance boundary follows the service area boundary for 9.65 miles to the 9,200 foot contour line. The boundary then intersects Bear Creek. Here the attainment/maintenance boundary diverges from the service area boundary (9,200 foot contour line). The attainment/maintenance boundary continues in a west, southwest direction for 0.92 miles from the intersection of the 9,200 foot contour line and Bear Creek to the top of ski lift number 9 in the Telluride Ski Area at an elevation of about 11,900 feet. The boundary then shifts and runs in a north-westerly direction for 0.83 miles from the top of lift 9 to the top of lift 7, which is located at an elevation of 10,490 feet. From the top of lift 7, the attainment/maintenance boundary continues in a north-westerly direction for 0.5 miles to the intersection of lift 3 with the 10,000 foot control line. The attainment/maintenance boundary follows the 10,000 foot contour line in a south, south-west direction for 3.2 miles, until it intersects Skunk Creek. Here the boundary diverges from the 10,000 foot contour line and follows Skunk Creek in a northerly direction for 2.25 miles. At the intersection of Skunk Creek and Colorado State Highway 145, the attainment/maintenance boundary leaves the creek and follows Highway 145 in a northerly direction until it meets the service area boundary as it existed prior to changes adopted in 1991. | ||||

| 1 Includes any Indian country in each county or area, unless otherwise specified. EPA is not determining the boundaries of any area of Indian country in this table, including any area of Indian country located in the larger designation area. The inclusion of any Indian country in the designation area is not a determination that the state has regulatory authority under the Clean Air Act for such Indian country. 2 This date is August 3, 2018, unless otherwise noted. 3 EPA revised the nonattainment boundary in response to a court decision, which did not vacate any designations for the 2015 ozone NAAQS, but which remanded the designation for the identified county. Because this additional area is part of a previously designated nonattainment area, the implementation dates for the overall nonattainment area ( e.g., the August 3, 2021 attainment date) remain unchanged regardless of this later designation date. | ||||

| 1 Includes any Indian country in each county or area, unless otherwise specified. EPA is not determining the boundaries of any area of Indian country in this table, including any area of Indian country located in the larger designation area. The inclusion of any Indian country in the designation area is not a determination that the state has regulatory authority under the Clean Air Act for such Indian country. 2 This date is August 3, 2018, unless otherwise noted. 3 EPA revised the nonattainment boundary in response to a court decision, which did not vacate any designations for the 2015 ozone NAAQS, but which remanded the designation for the identified county. Because this additional area is part of a previously designated nonattainment area, the implementation dates for the overall nonattainment area ( e.g., the August 3, 2021 attainment date) remain unchanged regardless of this later designation date. | ||||
