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.
