Mid-Atlantic Regional Air Management Association is a regional air quality planning organization serving state and local air regulatory agencies and stakeholders in the Mid-Atlantic United States. Founded in the early 1990s, it coordinates technical analysis, regional modeling, policy development, and stakeholder engagement to address ozone, particulate matter, and regional haze across a multi-state airshed. The association works with federal agencies, metropolitan planning organizations, environmental advocacy groups, public utilities, and industrial operators to develop emissions inventories, modeling protocols, and transportation conformity analyses.

History

The association was established in the aftermath of federal regulatory developments driven by the Clean Air Act Amendments of 1990, when interstate ozone transport issues became prominent after litigation such as Virginia v. EPA and rulemakings by the United States Environmental Protection Agency. Early participants included agencies from Pennsylvania, New Jersey, Delaware, Maryland, New York, Connecticut, and regional entities like the Metropolitan Washington Council of Governments and the Delaware Valley Regional Planning Commission. The organization built on precedents set by regional collaboratives such as the Ozone Transport Commission and multi-state committees formed under the Regional Greenhouse Gas Initiative framework. Over successive planning cycles for National Ambient Air Quality Standards established by the EPA—including revisions for ozone and particulate matter—the association institutionalized cooperative modeling practices and emissions inventory harmonization across the Mid-Atlantic airshed.

Organization and Governance

Governance is typically exercised through a board composed of directors representing member state air agencies, county health departments, and metropolitan planning organizations such as the Pittsburgh Regional Transit, Southeastern Pennsylvania Transportation Authority, and the New Jersey Department of Environmental Protection (NJDEP). Technical committees bring together staff from the EPA Region 3, academic partners like Rutgers University, Pennsylvania State University, Johns Hopkins University, and consultants with experience in photochemical modeling such as those affiliated with the Community Multiscale Air Quality (CMAQ) modeling system and the Models-3/SMOKE modeling frameworks. Decision-making follows bylaws adopted by delegates, with executive leadership provided by an executive director and a small secretariat, often funded through cooperative agreements with state agencies and grants from federal programs administered via the EPA Office of Air and Radiation.

Programs and Initiatives

Programs centralize around regional emissions inventories, transport modeling, and control strategy development. The association conducts coordinated inventories that reconcile data from state inventories like the NEI and mobile source inputs from the Federal Highway Administration, working with transit agencies such as SEPTA and the Maryland Transit Administration. It sponsors regional modeling projects employing CMAQ and meteorological inputs from the Weather Research and Forecasting Model, and supports analyses for regional haze planning required by the Visibility Protection provisions. Outreach initiatives connect with stakeholders including American Lung Association, Natural Resources Defense Council, Exelon Corporation, PSEG, and community groups to design emissions reduction measures targeting power plants, mobile sources, and industrial facilities regulated under permits like those issued by New York State Department of Environmental Conservation.

Membership and Partnerships

Members include state environmental agencies—Pennsylvania Department of Environmental Protection, New Jersey Department of Environmental Protection, Maryland Department of the Environment, Delaware Department of Natural Resources and Environmental Control—and local air quality management districts such as the Philadelphia Department of Public Health and county health departments in Baltimore County and Allegheny County. Partnerships extend to federal partners like the EPA, regional planning bodies such as the Metropolitan Planning Organization network, universities including Drexel University and University of Maryland, College Park, industry associations like the American Petroleum Institute, and advocacy groups including Sierra Club and Environmental Defense Fund. The association often collaborates with interstate entities such as the New England Interstate Water Pollution Control Commission for cross-border air and environmental issues.

Funding and Budget

Funding sources historically combine state contributions, project-specific grants, and cooperative agreements. Significant support has come through federal pass-through funding from the EPA under programs related to air quality modeling and technical assistance, supplemented by grant awards from foundations and contracts with utilities and metropolitan agencies. Budget priorities allocate funds to staff salaries, modeling hardware and software licenses, emissions inventory databases, and stakeholder engagement forums. Fiscal oversight is provided by member-state fiscal agents and audited according to state procurement rules and federal grant compliance standards such as those administered by the Office of Management and Budget circulars.

Impact and Results

The association’s coordinated modeling and inventory work has contributed to successful state implementation plans that resulted in redesignations and attainment demonstrations under National Ambient Air Quality Standards for ozone and PM2.5. Regional analyses supported rulemakings that affected emissions from sources regulated under Title V permits and informed interstate transport remedies adopted following Cross-State Air Pollution Rule litigation and policy debates involving the Supreme Court of the United States. Outcomes include harmonized emissions inventories used by the EPA National Emissions Inventory, more consistent transportation conformity determinations involving metropolitan planning organizations like MPOs, and technical capacity-building through workshops with academic partners. The association’s work has been cited in state regulatory filings, environmental impact assessments reviewed by the Council on Environmental Quality, and in peer-reviewed studies published by researchers at institutions such as Rutgers University and Johns Hopkins University demonstrating emissions trends and public health co-benefits.
