2007 Enhanced I/M Program Annual Report
Complete downloadable report PDF (1.5 mb, 63 pgs)
The United States Environmental Protection Agency (USEPA or EPA) has defined the reporting requirements for all state-run vehicle Inspection/Maintenance (I/M) programs in 40 CFR Part 51.366 (7-1-05 Edition). The I/M program for the State of New York (the State, or NYS) is jointly administered by the New York State Department of Environmental Conservation (NYSDEC) and the Department of Motor Vehicles (NYSDMV). This report reflects the coordination between the two agencies, and is being submitted to the EPA to fulfill the State's annual reporting requirements for the calendar year of 2007.
In the nine counties of the New York Metropolitan Area (NYMA), the State has had an I/M program based on an idle test since 1981, and a high enhanced I/M program since 1998 using a mass emission transient test, referred to as the New York Transient Emission Short Test (NYTEST). On April 1, 2005, the State commenced an on-board-diagnostic (OBD) II-based vehicle inspection program, named the New York Vehicle Inspection Program (NYVIP). By May 5, 2005 all testing facilities in NYMA were required to conduct OBD II inspections for all applicable 1996 and later model year light duty vehicles (LDVs) and light duty trucks (LDTs). During calendar year 2007, more than 4.3 million vehicles and trucks were registered in NYMA, of which 3,669,143 (85.21% of the total registered) were emissions tested, and 2,940,794 (80.15% of the emissions tested vehicles) had OBD II inspections.
Since 1998, a low enhanced I/M program has been operating in the remaining 53 counties of New York (Upstate). On December 1, 2004, the State implemented the OBD II-based NYVIP Upstate. This allowed for the inclusion of all Upstate vehicles into the State's I/M program database. In 2007, more than 4.7 million vehicles and trucks were registered in Upstate, 3,212,615 of them (or 68.30%) received OBD II inspections.
Pursuant to a Consent Order filed on September 6, 1977, all yellow medallion taxi cabs operating in New York City, under the jurisdiction of the New York City Taxi Limousine Commission (NYC TLC, or TLC), are required to be emissions-tested on a three-times-per-year basis. Beginning in 1981, all TLC vehicles were subjected to the idle test. Following upgrades to their Woodside testing facility, the TLC commenced an OBD II inspection program for their taxi fleet on December 8, 2003. This program continued in 2007 for their fleet of 14,702 vehicles (12,516 LDVs and 2,186 LDTs), with a total 37,442 OBD II inspections performed.
The State's goal is to continue to improve the performance of these I/M Programs. New York State will continue to utilize the March 1996 I/M State Implementation Plan (SIP) and the May 2006 NYVIP SIP as the reference documents for delineation of necessary programs, objectives, and goals. New York will maintain and implement measures along these lines to achieve its intended goal: cleaner air for the residents of the State of New York.
