Mid-Atlantic State Implementation Plans (SIPs)

This web page contains links to information on the EPA-approved State Implementation Plan (SIP) regulations for the following Mid-Atlantic state and local air quality agencies:

A SIP is a plan for each state which identifies how the state will meet the National Ambient Air Quality Standards (NAAQS) and certain other requirements of the Clean Air Act. SIPs typically consist of narratives, or rules, or both. Sometimes SIPs include other forms of requirements such as emissions inventories, evidence of state legal authority, or permits. See General SIP Requirements. The states prepare SIPs and submit them to EPA for approval to meet specific requirements of the Clean Air Act ("the Act"), including the requirement to attain and maintain the National Ambient Air Quality Standards (NAAQS). SIP narratives describe how the plan, including any rules or other requirements, will comply with these requirements and maintain the NAAQS. SIP narratives also sometimes include state promises for future action, which we call commitments. Once EPA approves a SIP, EPA and citizens may enforce the SIP rules, requirements, and commitments in Federal court.

The Clean Air Act also requires EPA to assemble and publish, on a periodic basis, a comprehensive document setting forth the applicable SIP requirement for each state. This Web page supports this requirement, set forth in Section 110(h) of the Act, by compiling the EPA- approved SIP rules and regulations for the listed states. Later this year, we will add to this page a document for each State listing the EPA-approved source-specific requirements for these states.

This web page only includes the requirements that EPA has approved into the SIP for the states mentioned above. You should consult state web sites to view the state-approved air quality regulations that may or may not have been approved into the SIP. Please note that the air quality rules on the state Web sites may differ from what is contained in our database. This may happen because a state has yet to submit a rule or rule revision to us for approval, or we have not approved a rule or rule revision that a state has submitted. Without our approval, a state's change to a rule contained in the EPA- approved SIP has no affect on our or citizens' authority to enforce the EPA-approved rule in Federal court.

This web page does not include the narrative portion of our SIPs, but this web site contains summaries of currently existing attainment and maintenance plans, rate of progress plans, early action compact (EAC) plans, and SIP commitments for the Region 3 states.

For further information regarding the SIP narratives, please contact Sharon McCauley at (215) 814-3376 or at McCauley.Sharon@epa.gov.

We have attempted to ensure that the information provided in this web page accurately reflects EPA's final actions on state SIP submissions as published in the Federal Register (FR) and codified in the Code of Federal Regulations (CFR). If there are discrepancies, however, the CFR and the FR is the official record. Our omission of any SIP requirement from this web page does not alter citizens' or our ability to enforce such requirements.

For a more detailed description of SIPs, see our web page entitled "What is a SIP?"

Superseded/Rescinded Date: Indicates the Federal Register publication date when a SIP requirement has been superseded or rescinded by subsequent EPA action.
