                 TITLE 42--THE PUBLIC HEALTH AND WELFARE
 
            CHAPTER 85--AIR POLLUTION PREVENTION AND CONTROL
 
                  SUBCHAPTER I--PROGRAMS AND ACTIVITIES
 
     Part C--Prevention of Significant Deterioration of Air Quality
 
                          subpart i--clean air
 
Sec. 7476. Other pollutants


(a) Hydrocarbons, carbon monoxide, petrochemical oxidants, and nitrogen 
        oxides

    In the case of the pollutants hydrocarbons, carbon monoxide, 
photochemical oxidants, and nitrogen oxides, the Administrator shall 
conduct a study and not later than two years after August 7, 1977, 
promulgate regulations to prevent the significant deterioration of air 
quality which would result from the emissions of such pollutants. In the 
case of pollutants for which national ambient air quality standards are 
promulgated after August 7, 1977, he shall promulgate such regulations 
not more than 2 years after the date of promulgation of such standards.

(b) Effective date of regulations

    Regulations referred to in subsection (a) of this section shall 
become effective one year after the date of promulgation. Within 21 
months after such date of promulgation such plan revision shall be 
submitted to the Administrator who shall approve or disapprove the plan 
within 25 months after such date or promulgation in the same manner as 
required under section 7410 of this title.

(c) Contents of regulations

    Such regulations shall provide specific numerical measures against 
which permit applications may be evaluated, a framework for stimulating 
improved control technology, protection of air quality values, and 
fulfill the goals and purposes set forth in section 7401 and section 
7470 of this title.

(d) Specific measures to fulfill goals and purposes

    The regulations of the Administrator under subsection (a) of this 
section shall provide specific measures at least as effective as the 
increments established in section 7473 of this title to fulfill such 
goals and purposes, and may contain air quality increments, emission 
density requirements, or other measures.

(e) Area classification plan not required

    With respect to any air pollutant for which a national ambient air 
quality standard is established other than sulfur oxides or particulate 
matter, an area classification plan shall not be required under this 
section if the implementation plan adopted by the State and submitted 
for the Administrator's approval or promulgated by the Administrator 
under section 7410(c) of this title contains other provisions which when 
considered as a whole, the Administrator finds will carry out the 
purposes in section 7470 of this title at least as effectively as an 
area classification plan for such pollutant. Such other provisions 
referred to in the preceding sentence need not require the establishment 
of maximum allowable increases with respect to such pollutant for any 
area to which this section applies.

(f) PM-10 increments

    The Administrator is authorized to substitute, for the maximum 
allowable increases in particulate matter specified in section 7473(b) 
of this title and section 7475(d)(2)(C)(iv) of this title, maximum 
allowable increases in particulate matter with an aerodynamic diameter 
smaller than or equal to 10 micrometers. Such substituted maximum 
allowable increases shall be of equal stringency in effect as those 
specified in the provisions for which they are substituted. Until the 
Administrator promulgates regulations under the authority of this 
subsection, the current maximum allowable increases in concentrations of 
particulate matter shall remain in effect.
