Proposed Revision to the State Implementation Plan for Ozone for the Philadelphia Ozone Nonattainment Area; Public Hearing

[29 Pa.B. 4390]

   Ground-level ozone concentrations above the Federal health-based standard are a serious human health threat and can also cause damage to crops, forests and wildlife. The Department of Environmental Protection is seeking public comment on a State implementation plan (SIP) revision for the Philadelphia ozone nonattainment area (Bucks, Chester, Delaware, Montgomery and Philadelphia counties) which reduces volatile organic compounds (or equivalent) by 3% per year from 1996 through 2005 and demonstrates that the area will meet the health-based ozone standard.

   The proposed SIP revises the highway vehicle emission inventory submitted to the EPA and establishes new motor vehicle emission budgets for purposes of transportation conformity. The United States Environmental Protection Agency has required areas classified as serious and above for ozone to include in their SIPs all control measures which will be in place by the attainment year and which are assumed in the air quality attainment demonstration (last submitted to the EPA on August 21, 1998). This proposed SIP thus includes emission reductions attributable to the National Low Emission Vehicle program already in place and additional Federal heavy-duty engine standards effective 2004. These strategies were not included in the motor vehicle emissions inventory originally submitted to the EPA on April 30, 1998.

   This proposal is available on the DEP Website at (choose Information by Subject/Air Quality/State Implementation Plans), or through the contact persons listed.

   The Department will hold a public hearing to receive comments on the SIP revision on Friday, September 17, 1999 at 1 p.m. at the offices of the Delaware Valley Regional Planning Commission, The Bourse Building, 8th Floor, (use 4th Street side elevators), 111 S. Independence Mall East, Philadelphia.

   Persons wishing to present testimony at the hearing should contact Shiela Barley, (717) 787-9495 (P. O. Box 8468, Harrisburg, PA 17105) to reserve a time. If individuals do not reserve a time, they will be able to testify after preregistrants. Witnesses should keep testimony to 10 minutes and should provide two written copies at the hearing. Persons with a disability who wish to attend the hearing and require an auxiliary aid, service or other accommodation to participate in the proceeding should contact Wick Havens at the telephone number mentioned previously. TDD users may contact the AT&T Relay Service at (800) 654-5984 to discuss how the Department can best accommodate their needs.

   Written comments should be sent to Arleen Shulman, Chief, Mobile Sources Section Chief, Bureau of Air Quality, P. O. Box 8468, Harrisburg, PA 17105-8468 no later than close of business on September 20, 1999.
