Enhanced I/M Program Evaluation Report - June 2012 - June 2014

Downloadable report PDF (1.05 MB, 29 pgs) (Appendix D and E available upon request)

Biennial long-term program evaluations are required for enhanced I/M programs under 40 CFR Part 51.353(c)(1) of the federal Inspection/Maintenance (I/M) rule. Program evaluation provides a mechanism for I/M jurisdictions to evaluate the effectiveness of their programs, and if appropriate, to make enhancements to operating programs. The New York State Department of Environmental Conservation (DEC) submitted seven biennial program evaluations to the United States Environmental Protection Agency (EPA), as dated January 2001, November 2002, October 2004, February 2007, March 2009, October 2010, and October 2012. This document retains the reporting format used for the past submissions.

Previous program evaluation reports devoted sections specifically to the former tailpipe-based New York Transient Emission Short Test (NYTEST) I/M program. NYTEST emissions inspections were completed in the nine-county New York Metropolitan Area (NYMA) I/M area from November 15, 1998 to December 31, 2010. NYMA includes New York City (Bronx, Kings, New York, Queens, and Richmond Counties), Long Island (Nassau and Suffolk Counties), Rockland County, and Westchester County. This and future program evaluation reports will no longer include emissions testing completed under the former NYTEST I/M program.

DEC and the New York State Department of Motor Vehicles (DMV) jointly administer New York's I/M programs. During the subject time period, New York State operated two enhanced I/M programs, the former New York Vehicle Inspection Program (NYVIP) and its successor, the New York Vehicle Inspection Program 2 (NYVIP2). During October 2013 to January 2014, both NYVIP and NYVIP2 equipment were in use to allow for transition to NYVIP2 only. The last NYVIP inspection was completed on January 15, 2014.

The NYVIP and NYVIP2 programs have effectively reduced hydrocarbon, carbon monoxide, and nitrogen oxide emissions from applicable motor vehicles through required emissions inspections and proper vehicle maintenance and repair. This report also details the overall progression of New York's enhanced I/M programs.
The following components have contributed to the effectiveness of NYVIP/NYVIP2 programs:

  1. New York State requires mandatory, statewide (62 counties) emissions inspections on an annual frequency and upon change of ownership. NYMA complies with the high enhanced performance standard defined under 40 CFR Subpart S §51.351(f). The 53-county "Upstate I/M Area" complies with the Ozone Transport Region (OTR) low enhanced I/M performance standard defined under §51.351(h);
  2. Through the combination of sticker and registration-based denial enforcement (RBE), New York's motorist compliance rate exceeds the minimum performance standard requirements for enhanced I/M programs;
  3. Since May 2005, mandatory on-board diagnostic (OBD II) inspections have been required statewide. New York's on-board diagnostics emissions inspection was developed in accordance with EPA's final OBD implementation guidance and 40 CFR Parts 51 and 86. New York outlined the components of the OBD II-based NYVIP program within its March 2006 and July 2009 State Implementation Plan (SIP) revisions. These SIP revisions have been approved by EPA with final approval of the 2009 Revision being published in the Federal Register on February 28, 2012;
  4. DMV completed sticker compliance and program (enforcement) audits to ensure that New York's I/M programs maximize emission reductions. Several enforcement investigations involving DMV, DEC, and other governmental agencies were completed during the reporting period; and
  5. Since December 2003, the New York City Taxi and Limousine Commission (TLC) has operated a centralized, test-only OBDII inspection facility in Queens (Woodside). Applicable yellow medallion taxicabs and for-hire livery vehicles (FHVs) are required to receive safety/emissions inspections three times a year. All of the yellow medallion taxicab inspections are completed at the Woodside facility.

New York State also requires mandatory, annual emissions inspections for applicable heavy-duty, diesel-fueled vehicles (HDDVs) registered within NYMA. This report does not include an evaluation of the HDDV I/M program, but a general fact sheet can be found at: Section F of this report includes a brief description of the proposal to record HDDV I/M data into the NYVIP2 database.
