Air Quality Planning Program 

Maryland's Air Quality Planning Program (AQPP) writes state implementation plans and regulations to reduce emissions and achieve the 

National Ambient Air Quality Standards (NAAQS) for six "criteria" air pollutants: ground-level ozone, particulate matter, lead, carbon 

monoxide, nitrogen dioxide, and sulfur dioxide. The AQPP also implements federal, regional, local, and state greenhouse gas emissions

reduction programs, including implementing the requirements of the Maryland Greenhouse Gas Emissions Reduction Act of 2009 and 

managing Maryland's involvement in the Regional Greenhouse Gas Initiative (RGGI). 

The AQPP consists of three divisions covering its different program areas:

(1) Planning and Policy

(2) Regulation Development

(3) Climate Change

Planning and Policy: State Implementation Plans

The Planning and Policy Division develops air quality plans, also called state implementation plans, which are designed to attain and

maintain the National Ambient Air Quality Standards, and to prevent significant deterioration of air quality in areas cleaner than the 

standards.

The state implementation plans are listed below in chronological order with the latest documents first. Some SIPs have many 

appendices, but each distinct SIP on the list is identified with the word “Document” followed by the individual SIP’s name below that 

and any appendices subsequently.

Note: Maryland's State Implementation Plans are viewable in Adobe Acrobat Reader (pdf) format. To view the documents, you will have
