State Implementation Plan (SIP) Dashboard

What is a SIP?

New Jersey’s State Implementation Plan (SIP) for air quality is required by the Federal Clean Air Act (CAA).  It is the state’s plan for how it will attain or maintain compliance with the National Ambient Air Quality Standards (NAAQS) for an air quality control region, and in the case of a nonattainment area, by the attainment date established for the standard.

First, the ozone SIP Revision addresses the requirements of the Clean Air Act (CAA) regarding New Jersey’s plan for attaining the 2008 75 ppb 8-hour ozone NAAQS in its Northern New Jersey multi-state nonattainment area by its attainment date of July 20, 2021. Second, this SIP revision includes a Reasonably Available Control Technology (RACT) analysis to address both the 2008 75 ppb and the 2015 70 ppb NAAQS. Third, this SIP Revision addresses the submittal requirements for New Jersey’s NNSR permitting program for the 2008 75 ppb and 2015 70 ppb 8-hour ozone NAAQS and includes the required NNSR Program Compliance Certifications. Fourth, this SIP revision includes the 2017 periodic emissions inventory that will also be the base year inventory for RFP for the 2015 70 ppb 8-hour ozone NAAQS.
1971 Primary and Secondary Sulfur Dioxide (SO2) NAAQS Redesignation Request and Maintenance Plan

20211110

This SIP revision includes a limited maintenance plan requesting the USEPA to redesignate the Warren County nonattainment area to attainment in accordance with the Clean Air Act. This SIP revision meets the requirements for a limited maintenance plan which are: Attainment Inventory, Maintenance Demonstration, Monitoring Network, Verification of Continued Attainment, and Contingency Plan. This document acknowledges the improvement in outdoor sulfur dioxide air quality by demonstrating that SO2 levels are currently well below 85 percent of the SO2 National Ambient Air Quality Standards (NAAQS).
Permit and Reporting Requirements for Fumigants and Other HAPs

20210301

This proposed rule and SIP revision represents a continuation of the Department’s efforts to address air contaminants in New Jersey through its permitting and emission statements programs. The proposed rulemaking would regulate fumigants and fumigation operations based on potential to emit, rather than weight of raw materials, to provide clarity on the regulatory requirements for these operations. The Department also proposes to regulate three air contaminants that are not currently regulated by the State, to be referred to as New Jersey Hazardous Air Pollutants, and to add 13 air contaminants to the list of toxic air pollutants that must be included in an emission statement submitted by a source otherwise subject to emission statement requirements. The proposed rulemaking includes penalty provisions at N.J.A.C. 7:27A for the proposed amendments to the Air Pollution Control rules.

The proposal also constitutes a revision to New Jersey’s State Implementation Plan (SIP) for the attainment and maintenance of the National Ambient Air Quality Standards for ozone. To the extent that the proposed amendments, repeal, and new rules impact rules in the SIP, this rulemaking constitutes a revision to the SIP. The proposed amendments and new rule at N.J.A.C. 7:27-22 do not constitute a revision to the SIP as those provisions at N.J.A.C. 7:27-22 are not part of the SIP.

This SIP revision is to protect and improve visibility levels in New Jersey’s Class I Area, the Brigantine Wilderness Area of the Edwin B. Forsythe National Wildlife Refuge. This SIP revision establishes the progress goal for the second planning period (2018 – 2028) for the Brigantine Wilderness Area to help achieve the goal of reaching natural background visibility levels by 2064. This SIP revision also addresses other mandatory SIP elements for regional haze and related issues.
Infrastructure and Transport SIP Revision for the 70 ppb and 75 ppb 8-hour Ozone NAAQS and Negative Declaration for the Oil and Natural Gas Control Techniques Guidelines (CTGs)

20190513

First, this revision certifies New Jersey’s ability and authority to implement, maintain, and enforce the 2015 8-hour 70 ppb ozone NAAQS, addressing the infrastructure requirements of the Federal Clean Air Act (CAA) Section 110. Second, this revision addresses the interstate transport or “Good Neighbor” requirements of CAA Section 110 for both the 70 ppb and the 75 ppb ozone NAAQS. Third, this revision includes a negative declaration that the Oil and Natural Gas CTGs do not pertain to New Jersey.

This SIP Revision also addresses the submittal requirements for New Jersey’s Nonattainment New Source Review (NNSR) permitting program for implementing the 75 ppb 2008 ozone NAAQS and includes the required NNSR Program Compliance Certification.
Air Emission Control/Permitting Exemptions, Hazardous Air Pollutant Reporting Thresholds, and CAIR NOx Trading NOx Budget Trading Programs Repeal

20170807

This rule and SIP revision consists of three major categories. First, the Department is proposing to amend its permitting rules to provide exemptions for equipment that is used during and after natural and human-caused disasters, and other equipment that has a negligible environmental impact. Second, the Department is updating the HAP reporting thresholds using the most recent science-based methodologies. Third, the Department proposes to repeal N.J.A.C. 7:27-30, CAIR NOx Trading Program, and N.J.A.C. 7:27-31, NOx Budget Program, which have been Federally preempted. Additional proposed amendments conform the administrative penalties to the proposed rules and correct errors and inconsistencies. The proposed repeal and amendments to N.J.A.C. 7:27-22 do not constitute a revision to the SIP as those provisions of N.J.A.C. 7:27-22 are not part of the SIP.
Gasoline Transfer Operations, Phase I and Phase II Vapor Recovery Systems TBAC Repeal

Permitting Amendments

20171129

These rule amendments and SIP revision allow new gasoline dispensing facilities to be constructed without Phase II vapor recovery systems, require existing facilities with Phase II systems that are incompatible with onboard vapor recovery (ORVR) systems to decommission the Phase II systems within three years, and require upgrades to the Phase I vapor recovery, tank breathing, and refueling components.  They also repeal t-butyl acetate (TBAC) emissions reporting requirements and proposes amendments to major and minor source permitting requirements to state that the terms of the preconstruction permit are incorporated into and become part of the operating permit, and that the Department will publish public notice of a draft operating permit by posting the notice on its website, rather than in the newspaper.

This SIP revision implements 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.
