SUPPLEMENTARY INFORMATION:

Background

    EPA announced its intent to amend the I/M Program Requirements in 
December 1994 and held stakeholders' meetings on January 24, 1995 and 
January 31, 1995. The proposal creates a second, less stringent 
enhanced I/M performance standard that could be [[Page 26711]] used in 
areas that can demonstrate an ability to meet the 1990 Clean Air Act 
deadlines for Reasonable Further Progress and attainment while 
implementing an I/M program that falls below the originally promulgated 
enhanced I/M performance standard. The proposed action would also 
revise the high enhanced I/M performance standard to include a visual 
inspection of the positive crankcase ventilation (PCV) valve on all 
light-duty vehicles and light-duty trucks from model years 1968 to 
1971, inclusive, and of the exhaust gas recirculation (EGR) valve on 
all light-duty vehicles and light-duty trucks from model years 1972 
through 1983, inclusive. The proposal also solicits public comment on 
whether or not EPA should include revised regulatory language in its 
final rulemaking which change the population cutoff for basic I/M from 
50,000 persons to 200,000 persons. Lastly, the proposal would make 
clarifying amendments to the I/M requirements for areas undergoing 
redesignation.
