Proposed Revisions to Pennsylvania's State Implementation Plan

[38 Pa.B. 1216]
[Saturday, March 8, 2008]

   Section 110 of the Federal Clean Air Act (CAA) requires states to develop State Implementation Plans (SIP) and programs to meet the National Ambient Air Quality Standards (NAAQS) established by the United States Environmental Protection Agency (EPA) to protect public health and welfare. Section 110 of the CAA sets forth general elements for the implementation of SIPs. Section 110(a)(2) of the CAA requires states to submit SIP revisions to the Environmental Protection Agency (EPA) Administrator that provide for implementation, maintenance and enforcement of the NAAQS.

   The Department of Environmental Protection (Department) is seeking comment on a SIP revision that confirms the Commonwealth's compliance with section 110(a)(2)(K) of the CAA for fine PM2.5. Section 110(a)(2)(K) requires a state's SIP to provide for the performance of air quality modeling as EPA may prescribe to predict the effect on ambient air quality of emissions of air pollutants for which a NAAQS has been established. The SIP revision identifies the Commonwealth's legal authority and obligation to attain the PM2.5 NAAQS and to perform the modeling, and describes the process the Department is using to prepare and submit modeling for PM2.5, including its work with a cooperative regional consortium.

   The proposed SIP revision is available on the Department's web site at (choose Air Plans) or through the contact persons listed. The Department will hold a public hearing to receive comments on the proposals on Thursday, April 10, 2008, at 1 p.m. at the Department's Southcentral Regional Office, 909 Elmerton Avenue, Susquehanna Room A, Harrisburg, PA 17110.

   Persons wishing to present testimony at the hearing on the proposed SIP revisions should contact Yvette House, P. O. Box 8468, Harrisburg, PA 17105, (717) 787-9495, to reserve a time. Persons who do not reserve a time will be able to testify as time allows. Witnesses should limit testimony to 10 minutes and provide the Department with two written copies of their statement 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 Yvette House at or (717) 787-9495. TDD users may contact the AT&T Relay Service at (800) 654-5984 to discuss how the Department can best accommodate their needs.

   The Department must receive comments no later than April 10, 2008. Written comments should be sent to the attention of Arleen Shulman, Division of Air Resource Management, Bureau of Air Quality, P. O. Box 8468, Harrisburg, PA 17105-8468,
