Abstract |
In conjunction with an EPA project to assess methods, costs, projected effectiveness and acceptability of various motor vehicle exhaust emissions inspection and maintenance (I/M) alternatives, and to support the State of Texas in complying with its implementation plan, the Office of Mobile Source Air Pollution Control of the U.S. Environmental Protection Agency assisted the Texas Air Control Board in establishing a pilot motor vehicle emissions inspection and maintenance program in Houston, Texas. A portion of the program involved the operation of a centralized vehicle emissions inspection station which performed idle tests, underhood inspections of emission control systems and components, and physical/functional I/M tests to simulate the operation of the various alternative configurations for the legislatively mandated I/M program. |
