							 (a) shall remain in effect until December 31, 1991, and as of that date is
							 repealed unless a later regulation deletes or extends that date.
							 Notwithstanding the repeal or expiration of this regulation on December 31,
							 1991, the provisions of the regulation as they existed prior to such repeal or
							 expiration shall continue to be operative and effective for those events
							 occurring prior to the repeal of expiration.
2 "PC" means
							 passenger cars.
3 Equivalent
							 inertia weights are determined under subparagraph
							 40 CFR
							 86.129-79(a).
4 Hydrocarbon
							 standards in parentheses apply to total hydrocarbons.
5 The maximum
							 projected emissions of oxides of nitrogen measured on the federal Highway Fuel
							 Economy Test (HWFET; 40 CFR part 600 , Subpart B) shall be not greater than
							 1.33 times the applicable passenger car standards and 2.00 times the applicable
							 light-duty truck and medium-duty vehicle standards shown in the table. Both the
							 projected emissions and the HWFET standard shall be rounded to the nearest 0.1
							 gm/mi before being compared.
6 The second
							 set of 50,000 mile passenger car standards is optional. A manufacturer must
							 select either the primary or optional sets of 50,000 mile standards for its
							 full product line for both 1981 and 1982 model years.
7 For vehicles
							 from evaporative emission families with projected 50,000 mile evaporative
							 emissions values below 1.0 gm/test, an adjustment to the hydrocarbon exhaust
							 emission standards may be granted by the Executive Officer. The adjusted
							 standard will be calculated using the following formula:
HCex =
							 .75 (.185 - [(Di + 3.3 Hs) (29.4)])+ HCo
Where:
HCex =
							 adjusted exhaust hydrocarbon standard
HCo =
							 unadjusted exhaust hydrocarbon standard
Di= diurnal evaporative
							 emissions
Hs= hot soak evaporative
							 emissions.
(b)
				  The exhaust emissions from new 1982 model passenger cars, light-duty trucks,
				  and medium-duty vehicles, subject to registration and sold and registered in
				  this state, shall not exceed1:
