Proposed Revision to the State Implementation Plan; Vehicle Emissions Inspection/Maintenance Program Evaluation Methodology; Notice of Availability for Public Comment

[28 Pa.B. 6250]

   The Commonwealth of Pennsylvania, consistent with the provisions of 67 Pa. Code 177.24 and 40 CFR 51.353 (c), is required by the U.S. Environmental Protection Agency (EPA) to conduct an on-going biennial evaluation to establish the emission reductions achieved from its enhanced vehicle emissions inspection/maintenance (I/M) program. This program is currently in place in nine counties (Bucks, Chester, Delaware, Montgomery, Philadelphia, Allegheny, Beaver, Washington and Westmoreland counties). On October 30, 1998, EPA approved three alternative evaluation methods which it believes are more practical for states with decentralized programs than its original mass emissions transient testing evaluation method.

   The Commonwealth is seeking public comment on its choice of the Sierra Research Method for program evaluation. The Sierra Research method relies on statistical sampling and analysis of state I/M program data, modeling data and correlation to a base I/M program used as a benchmark for effectiveness.

   Three public hearings will be held as follows:

   Wednesday, January 20, 1999
11 a.m. to 1 p.m.
