Complete downloadable report PDF (1.3 mb, 102 pgs)
The United States Environmental Protection Agency (USEPA or EPA) has defined the reporting requirements for the States' motor vehicle Inspection/Maintenance (I/M) programs in the Code of Federal Regulations (40 CFR Part 51.366). The I/M program for the State of New York ("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 coordinated effort between the 2 agencies in administering the I/M program, and is being submitted to the EPA in order to fulfill the State's annual reporting requirements for the Calendar Year 2009.
In the 9 counties of the New York Metropolitan Area (NYMA), the State has administered an I/M program since 1981, initially based on an idle test. A high-enhanced I/M program using a mass emission transient test, referred to as the New York Transient Emission Short Test ("NYTEST"), has been in place since 1998. On April 1, 2005, the State commenced an on-board-diagnostic (OBD) II-based vehicle inspection program, referred to as 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 the Calendar Year 2009, more than 4.6 million LDVs and LDTs were registered within the NYMA, of which 3,843,690 vehicles (or 83.55% of the total registered) were emissions-tested, and 3,316,306 of them (or 86.28% of the emissions-tested vehicles) received OBD II inspections.
Since 1998, a low-enhanced I/M program has been in place for the remaining 53 counties of New York (Upstate New York) as part of the Ozone Transport Region (OTR). On December 1, 2004, the State fully implemented the OBD II-based NYVIP in Upstate New York. This allowed for the inclusion of all Upstate vehicles into the State's I/M program vehicle database. In Calendar Year 2009, more than 5.1 million LDVs and LDTs were registered in the Upstate I/M area, of which 4,191,744 vehicles (or 82.05% of the total registered) were emissions-tested, and 3,585,445 of them (or 85.54% of the emissions-tested vehicles) 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 and Limousine Commission (NYCTLC, or TLC), are required to be emissions-tested on a three-times-per-year basis. 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 2009 for their fleet of 17,827 vehicles (13,398 LDVs and 4,429 LDTs), with a total of 40,995 OBD II inspections performed.
New York will continue to maintain and implement measures consistent with the State Implementation Plan (SIP) in order to achieve its intended goal of healthy, clean air for the residents of the State of New York.
