Particulate matter (PM) is the general term used for a mixture of solid particles and liquid droplets found in the air. Fine particles are those that are less than 2.5 micrometers in diameter (PM2.5). Fine particles may be emitted directly by a source or formed in the atmosphere.
The federal government set a National Ambient Air Quality Standard for PM2.5 to protect public health in 1997 and revised the standard in 2006. For areas that do not meet the standard, the state must submit a State Implementation Plan (SIP) to the EPA that outlines the measures that will be taken to attain the health-based PM2.5 standard. States may also submit maintenance plans to the EPA that detail how the state will assure the standard will continue to be met for the next 10 years.
Proposed Maintenance Plan (SIP Revision) and Redesignation Request for the 1997 PM2.5 Standard: Reading Area - Final and Proposed
Proposed Revisions to the Motor Vehicle Emissions Budgets in the State Implementation Plan for the Philadelphia PM2.5 Nonattainment Area The department had sought comment on revisions that update the motor vehicle emissions budgets contained in the "State Implementation Plan: Pennsylvania Portion of the Philadelphia-Wilmington, PA-NJ-DE 1997 Fine Particulate Matter Nonattainment Area." The comment period ended December 17, 2012.
Ground-level ozone pollution occurs when hydrocarbons and nitrogen
oxides bake in the sun. These gases come from unburned fuel and
solvents, car exhaust, factory stack emissions and homeowners' and
individuals' activities. The federal government set a National
Ambient Air Quality Standard for ozone to protect public
health. For areas that do not meet the standard, the state must
submit a State Implementation Plan (SIP) to the EPA that outlines
the measures that will be taken to attain the health-based ozone
standard. States may also submit maintenance
plans to the EPA that detail how the state will assure the standard
will continue to be met for the next 10 years.
Proposed SIP Revision to Update Motor Vehicle Emissions Budgets for the Scranton/Wilkes-Barre Ozone Nonattainment Area Since no one expressed an interest in testifying at the public hearing for this SIP by Nov. 27, 2013, the hearing was cancelled.
Redesignation Requests, Maintenance Plans and 2002 Base Year Inventories
Once an area has attained a National Ambient Air Quality Standard, a state may request that EPA redesignate the area to attainment. In order to qualify for redesignation, a state must submit a maintenance plan, demonstrating that the area can continue to attain the standard for at least ten years after redesignation to attainment. Appendices to all documents are available upon request by contacting the Division of Air Resource Management at 717-787-9495. Pa. Bulletin Notice
Carbon monoxide is a byproduct of the incomplete burning of fuels. Industrial processes contribute to carbon monoxide pollution levels, but the principal source of carbon monoxide in most large urban areas is vehicle emissions. Peak carbon monoxide concentrations typically occur during the colder months of the year when automotive emissions are greater and nighttime inversion conditions are more frequent. The EPA has established a National Ambient Air Quality Standard for CO to protect public health.
Reducing Sulfur Dioxide (SO2)
Sulfur dioxide is a gaseous pollutant that is emitted primarily by industrial furnaces or power plants burning coal or oil containing sulfur. The major health effects associated with high exposures to sulfur dioxide include effects on breathing and respiratory illness symptoms. The environmental effects include plant damage, visibility impairment, acid rain and damage to structures. The EPA has established a National Ambient Air Quality Standard for SO2 to protect public health.
Final Warren County SIP Revision - Conewango Township, Pleasant Township, Glade Township, and City of Warren, Warren County SO2 Maintenance Plan and Redesignation Request (5/04)
Section 111 of the federal Clean Air Act contains a priority list of pollution sources that states must regulate. New sources must meet certain performance standards, and existing sources must meet prescribed emissions guidelines. The following plans aim to reduce toxic emissions and meet these standards.
Section 111(d)/129 State Plan for Hospital/Medical/Infectious Waste Incinerators (9/98)
Vehicles emit a number of harmful air pollutants that have the
potential to adversely affect people's respiratory systems. These
chemicals and particles are particularly dangerous for children,
the elderly and those with existing respiratory problems such as
asthma. As people increasingly depend on their cars and drive more
and more miles, it is important that the vehicles' exhaust systems
become cleaner. The following plans aim to reduce air pollution
resulting from automobiles and other vehicles to help Pennsylvania
attain the health-based ozone standard.
State Implementation Plan Revision Incorporating the Amended Pennsylvania Clean Vehicles Program. DEP has submitted to EPA for approval a revision to the State Implementation Plan (SIP). The SIP revision incorporates the recently amended Pennsylvania Clean Vehicles (PCV) program requirements.

Allegheny County Health Department
The Allegheny County Health Department maintains information on SIP revisions it has developed. See their page at: Air Quality Regulations
The Allegheny County Board of Health is seeking comments on several changes to its regulations, some of which will then be submitted to EPA as a revision to the State Implementation Plan. The county will accept comments through Jan. 9, 2013. Information on the public comment period is available under “Hot Topics”. The proposed SIP revision is available under “Currently Proposed SIP Revisions".
Final SIP Revision to incorporate New Source Review regulations. Submitted to the EPA June 25, 2012.
The Philadelphia County Dept. of Health, Air Management Services Division maintains information on SIP revisions it is developing at this page, under "Public Meetings & Notices". Below are prior submittals they have provided us.
