New Jersey: 1 Hour Ozone Attainment Demonstrations

Federal Register Dates:
December 16, 1999 Proposal 64 FR 70380
February 4, 2002 Final Rule 67 FR 5152

EPA Approval Date:
EPA's approval of New Jersey's 1 Hour Ozone Attainment Demonstration was effective on March 6, 2002.

State Submittal:
On August 31, 1998, Commissioner Shinn of the New Jersey Department of Environmental Protection (NJDEP) submitted to EPA a SIP revision "Attainment and Maintenance of the Ozone National Ambient Air Quality Standards--Meeting the Requirements of the Alternate Ozone Attainment Demonstration Policy," and supplements submitted on October 16, 1998, and April 26, 2000.

Affected Areas:
New Jersey portions of two severe ozone nonattainment areas
the New York-Northern New Jersey-Long Island Area, and the Philadelphia-Wilmington-Trenton Area.

New York-Northern New Jersey-Long Island Area includes: Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex, and Union Counties.

Philadelphia-Wilmington-Trenton Area includes: Burlington, Camden, Cumberland, Gloucester, Mercer, and Salem Counties.

New Jersey submitted a 1-hour ozone attainment demonstration. This demonstration consisted of: photochemical grid modeling results for three episodes representing different weather conditions, additional evidence to demonstrate attainment for the two nonattainment areas, VOC and NOx emission inventories, and identification of control measures needed to attain. EPA evaluated this information and performed additional analysis and concluded that additional assurances were needed to conclusively determine that the New Jersey 1-hour Ozone Attainment SIP will result in attainment. New Jersey provided this assurance by committing to adopt additional control measures which would result in the EPA-identified VOC and NOx emission reductions and to perform a mid-course review which would determine whether New Jersey was still on track to attain.

New Regulations Included As Part of the SIP:
No new or revised regulations were included in this SIP revision.
