New Jersey Ozone: 15 Percent Rate of Progress Plan and Phase I and II Ozone Implementation Plans

Federal Register Dates:
April 30, 1997 Proposal 62 FR 23410
June 30, 1997 Interim final rule 62 FR 35100

EPA Approval Date:
EPA's approval and interim approval were effective on July 30, 1997.

State Submittal:
SIP revisions dated December 31, 1996 and February 25, 1997.

Affected Areas:
Statewide and two severe nonattainment areas

EPA is approving revisions to the 1990 base year ozone emission inventory; the 1996 and 1999 ozone projection emission inventories; photochemical assessment monitoring stations network; demonstration that emissions from growth in vehicle miles traveled will not increase motor vehicle emissions and, therefore, offsetting measures are not necessary; modeling efforts completed to date; transportation conformity budgets; and enforceable commitments.

EPA is also giving conditional interim approval to New Jersey's 15 Percent Rate of Progress Plan and the 9 Percent Reasonable Further Progress Plan.

New Regulations Included As Part of the SIP:

In a letter dated May 29, 1997, New Jersey committed to perform the remodeling necessary to estimate the emissions reductions that will result from the enhanced I/M program as implemented within 12 months from the effective date of today's rulemaking.

As part of the remodeling of the enhanced I/M program, New Jersey must demonstrate that the 15 percent and 9 percent emission reductions are still being achieved in the Northern New Jersey and Trenton nonattainment areas as required by sections 182(b)(1) and 182(c)(2)(B) of the CAA and in accordance with EPA's policies and guidance.
