                                 Introduction

      The purpose of this report is to summarize the action taken with respect to
designations and classifications of ozone and carbon monoxide areas by EPA
published in the Federal Register in November 1991. The Clean Air Act
Amendments of 1990 (November 15, 1990) required States to submit to EPA a list of
areas to be designated nonattainment.  EPA is required to promulgate that list
(adding areas as appropriate) in the Federal Register.  Any area designated
nonattainment prior to November 15, 1990, is still designated nonattainment by
operation of law. EPA is also required  to classify these areas into various
classifications.  These classifications and relevant sections of the Act are included in
this report.

      For further information concerning a nonattainment area, the  user should
contact the State or Regional Office. A list of the Regional Offices and the
appropriate contact is included. Any corrections to this report should be sent to
Barry Gilbert (address on last page).

Notes:
Ozone  Nonattainment Classifications
      Extreme
      Severe-17 (17 years to attain and design value is based on 1986-88 data)
      Severe-15 (15 years to attain)
      Serious
      Moderate
      Marginal
      Sub-Marginal (Kansas City is violating but  has a design value <.121  ppm)
                  i                   ,
      Prior Designation Retained by Operation of Law
            Transitional  (Complete data for 1987-89 showing no  violation)
            Incomplete or No Data
                  (Inadequate data for 1987-89, but showing no violation)

Carbon Monoxide Nonattainment Classifications
      Serious
      Moderate >12.7 ppm
      Moderate < = 12.7 ppm

      Prior Designation Retained by Operation of Law
            Not Classified (No measured violation or no data)

SIP Call     In 1988  and 1989 EPA formally notified the Governors  in several States
           .that their State Implementation Plans for certain areas are substantially
            inadequate and called upon those States to revise their plans. (See the
            Federal  Register of July 30,  1990, page 30973.)

 Sec. 107 (d) Designations.—
 (4) Nonattalnment designations for ozone, carbon monoxide and participate matter (PM-10).—

        (A) Ozone and carbon monoxide.— (i) Within 120 days after the date of the enactment of the
 Clean Air Act Amendments of 1990, each Governor of each State shall submit to the Administrator a
 list that designates, affirms or reaffirms the designation of, or redesignates (as the case may be), all
 areas (or portions thereof) of the Governor's State as attainment, nonattainment, or unclassffiable with
 respect to the national ambient air quality standards for ozone and carbon monoxide.
               (ii) No later than 120 days after the date the Governor is required to submit the list of
        areas (or portions thereof) required under clause (i) of this subparagraph, the Administrator
        shall promulgate such designations, making such modifications as the Administrator may
        deem necessary, in the same manner, and under the  same procedure, as is applicable under
        clause (ii) of paragraph (1)(B), except that the phrase  "60 days* shall be substituted for the
        phrase '120 days" in that clause. If the Governor does not submit, in accordance with clause
        (i) of this subparagraph, a designation for an area (or  portion thereof), the Administrator shall
        promulgate the designation that the Administrator deems appropriate.
               (Hi) No nonattainment area may be redesignated as an attainment area under this
        subparagraph.
               (iv) Notwithstanding paragraph (1)(C)(ii) of this subsection, if an ozone or carbon
        monoxide nonattainment area located within a metropolitan statistical area or consolidated
        metropolitan statistical area (as established by the Bureau of the Census) is classified under
        part D of this title as a Serious, Severe, or Extreme Area, the boundaries of such area are
        hereby revised (on the date 45 days after such classification) by operation of law to include
        the entire metropolitan statistical area or consolidated  metropolitan statistical area,  as the case
        may be,  unless within such 45-day period the Governor (in consultation with State and local
        air pollution control agencies) notifies the Administrator that additional time is necessary to
        evaluate the application of clause (v). Whenever a Governor has submitted such a notice to
        the Administrator, such boundary revision shall occur on the later of the date 8 months after
        such classification or 14 months after the date of the enactment of the Clean Air Act Amend-
        ments of 1990 unless the Governor makes the finding  referred to in clause (v), and the
       'Administrator concurs in such finding, within such period. Except as otherwise provided in this
        paragraph, a boundary revision under this clause or clause (v) shall apply for purposes of any
        State implementation plan revision required to be submitted after the date of the enactment of
        the Clean Air Act Amendments of 1990.
              (v) Whenever the Governor of a State has submitted a notice under'clause  (iv), the
        Governor, in consultation with State and  local air pollution control agencies,  shall undertake a
        study to  evaluate whether the entire metropolitan  statistical area or consolidated metropolitan
        statistical area should be included within the nonattainment area. Whenever a Governor finds
        and demonstrates to the satisfaction of the Administrator, and the Administrator concurs in
        such finding, that with respect to a portion of a metropolitan statistical area or consolidated
        metropolitan statistical area, sources in the portion do  not contribute significantly to violation
        of the national ambient air quality standard, the Administrator shall approve the Governor's
        request to exclude such portion from the nonattainment area. In making such finding, the
        Governor and the Administrator shall consider factors such as population density, traffic
        congestion, commercial development, industrial development,  meteorological conditions, and
        pollution transport.

•SUBPART 2—ADDITIONAL PROVISIONS FOR  OZONE NONATTAINMENT AREAS
 SEC. 181. CLASSIFICATIONS AND ATTAINMENT DATES.
        (a) Classification and Attainment Dates for 1989 Nonattainment Areas.— (1) Each area
 designated nonattainment for ozone pursuant to section 107(d) shall be classified at the time of such
 designation, under table 1, by operation of law, as a Marginal  Area, a Moderate Area, a Serious Area,

-------
a Severe Area, or an Extreme Area based on the design value for the area. The design value shall be
calculated according to the interpretation methodology issued by the Administrator most recently
before the date of the enactment of the Clean Air Act Amendments of 1990. For each area classified
under thissubsection, the primary standard attainment date for ozone shall be as expeditiously as
practicable but not later than the date provided in table 1.

 Serious  	   0.160 up to 0.180	   9 years after
                                                               enactment
 Severe	   0.180 up to 0.280	   15 years after
                                                               enactment
 Extreme	   0.280 and above	   20 years after

 * The design value is measured in parts per million (ppm).
 ** The primary standard attainment date is measured from the date of the enactment of the Clean Air
Amendments of 1990.
       (2) Notwithstanding table'1, in the case of a severe area with a  1988 ozone design value
between 0.190 and 0.280 ppm, the attainment date shall be 17 years (in lieu of 15 years) after the
date of the enactment of the Clean Air Amendments of 1990.
       (3) At the time of publication of the notice under section 107(d)(4) (relating to area
designations) for each ozone nonattainment area, the Administrator shall publish a notice announcing
the classification of such ozone nonattainment area. The provisions of section 172(a)(1)(B) (relating to
lack  of notice and comment and judicial review) shall apply to such classification.
       (4) 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 Administrator may, in the Administrator's discretion, within 90
days after the initial classification, by the procedure required under paragraph (3), adjust the
classification to place the area in such,other category. 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.

Sec  181 (b) New Designations and Reclassifications.

       (3) Voluntary reclassification.— The Administrator shall grant the request of any State to
reclassify a nonattainment area in that State in accordance with table 1  of subsection (a)  to a higher
classification. The Administrator shall publish a notice in the Federal Register of any such request and
of action by the Administrator granting the request.


SEC. 185A. TRANSITIONAL AREAS.
       If an area  designated as an ozone nonattainment area as of the date of enactment of the
Clean Air Act Amendments of 1990 has not violated the national primary ambient air quality standard
for ozone for the 36-month period commencing on  January 1, 1987, and ending on December 31,

-------
1989, the Administrator shall suspend the application of the requirements of this subpart to such area
until December 31,1991. By June 30, 1992, the Administrator shall determine by order, based on the
area's design value as of the attainment date, whether the area attained such standard by December
31,1991. If the Administrator determines that the area attained the standard.the Administrator shall
require, as part of the order, the State to submit a maintenance plan for the area within 12 months of
such determination. If the Administrator determines that the area failed to attain the standard, the
Administrator shall, by June 30,1992, designate the area as nonattainment under section 107(d)(4).

SUBPART 3 — ADDITIONAL PROVISIONS FOR CARBON MONOXIDE NONATTAINMENT AREAS
SEC. 186. CLASSIFICATION AND ATTAINMENT DATES.

       (a) Classification by Operation of Law and Attainment Dates for Nonattainment Areas.— (1)
Each area designated nonattainment for carbon monoxide pursuant to section 107(d) shall be
classified at the time of such designation under table 1,  by operation of law, as a Moderate Area or a
Serious Area based on the design value for the area. The design value shall be calculated according
to the interpretation methodology issued by the Administrator most recently before the date of the
enactment of the Clean'Air Act Amendments of 1990. For each area classified under this subsection,
the primary standard attainment date for carbon monoxide shall be as expeditiously as practicable but
not later than the date provided in table  1:

       (2) At the time of publication of the notice required under section.107 (designating carbon
monoxide nonattainment areas), the Administrator shall publish a notice announcing the classification
of each such carbon monoxide nonattainment area. The provisions of section 172(a)(1)(B) (relating to
lack of notice-and-comment and judicial review) shall apply with respect to such classification.
       (3) 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 Administrator may, in the Administrator's discretion, within 90
days after the date of the enactment of the Clean Air Act Amendments of 1990 by the procedure
required under paragraph (2), adjust the classification of the area. In making such adjustment, the
Administrator may consider the number of exceedances of the national primary ambient air quality
standard  for carbon monoxide in the area, the level of pollution transport between the area and  the
other affected areas, and the  mix of sources and air pollutants in the area. The Administrator may
make the same adjustment for purposes of  paragraphs (2), (3), (6), and (7) of section 187(a).
