Notice of SIP Revision Proposal and Opportunity for a Public Hearing

Confirmation of Public Hearing
Proposed State Implementation Plan (SIP) Revision Sections 110(a)(1) and 110 (a)(2) for the Lead, Sulfur Dioxide, Nitrogen Dioxide,Ozone,PM2.5 and PM10, and Carbon Monoxide National Ambient Air Quality Standards and Regional Haze Commissioner Martin’s Letter to USEPA June 4, 2014 The State of New Jersey proposes to revise the State Implementation Plan (SIP) to address the Clean Air Act requirements for each state to address the infrastructure, transport, and regional haze requirements of the Clean Air Act Section 110. This proposed SIP revision demonstrates to the USEPA that the state has the authority (or infrastructure) to implement, maintain, and enforce an air quality management program that provides for attainment and maintenance of all National Ambient Air Quality Standards.

This certification document (“Certification”) addresses requirements under 42 U.S.C. § 7410(a)(1) and (2) (Sections 110(a)(1) and (2) of the Clean Air Act) for the 2006 daily 35 µg/m3 PM2.5 NAAQS.  New Jersey certifies compliance with these elements through its existing SIP, and as described in this Certification.

New Jersey Vehicle Inspection and Maintenance (I/M) Program - Rule Changes, I/M Program Modeling and Revised Performance Standard Modeling

Proposed

April 20, 2009

This SIP revision proposes to implement changes to its vehicle inspection and maintenance (I/M) program. Changes are being proposed to both Department and Motor Vehicle Commission (MVC) rules to implement these changes that include the following:

  • Emission tests will no longer require the use of a dynamometer.
  • Emission tests will include On-Board Diagnostics (OBD), gas cap, visible smoke and two-speed idle (TSI) tailpipe tests.
    Repair cost waiver provisions have been removed.
  • Gas cap testing is excluded for vehicles of model year 2001 and newer.
  • Certain classes of vehicles will require annual (more frequent) inspection.
  • Light duty diesel vehicles will now be subject to emission testing.

This SIP revision consists of the Department rule changes, the MVC rule changes, and an analysis showing the emissions impact of the proposed changes to the program.

Regional Haze

Final Best Available Retrofit Technology Determination

December 7, 2011

A SIP revision to protect and enhance visibility levels in the Brigantine Wilderness Area of the Edwin B. Forsythe National Wildlife Refuge, a federally designated Class I area. The purpose of this SIP revision is to establish the first Reasonable Progress Goal within the Class I area to help achieve the Congressionally mandated goal of reaching natural background visibility levels by the year 2064. The SIP revision demonstrates that New Jersey will meet the 2018 Uniform Rate of Progress set for Brigantine Wilderness Area by the deadline established in the USEPA regulations. The SIP revision also addresses other mandatory SIP elements for regional haze.

The Federal Clean Air Interstate Rule (CAIR) program, as established in the Federal rules, starts in 2009 for the annual and ozone season NOx control periods, and 2010 for the annual SO2 control period, and prescribes the participation by New Jersey’s large stationary combustion units in the Federal CAIR cap and trade programs at 40 CFR Part 97, which are designed to reduce emissions of NOx and SO2 in the eastern half of the United States. The Department's rules allocate the NOx allowances differently than the Federal rules to satisfy the Federal requirements for an abbreviated SIP for CAIR (40 CFR Part 97 Subpart EE and Subpart EEEE).
