This Section performs a wide variety of activities that help support current agency functions and also establish
future initiatives. It holds the primary responsibility for the development and periodic revision of the State
Implementation Plan (SIP). A State Implementation Plan is a federally enforceable strategy that details how a state
plans to attain and maintain compliance with National Ambient Air Quality Standards (NAAQS) mandated by the Clean
Air Act. A SIP consists of a state’s regulations and legal agreements limiting the amount of pollutant discharges to
the atmosphere. To insure that these regulations are sufficient to protect human health and welfare, a technical air
quality demonstration is often required. Usually this demonstration consists of evaluating monitored air quality
data, developing comprehensive source-specific emissions inventories and collecting meteorological data. This
information is then used in air dispersion modeling analyzes to determine the ambient concentrations of pollutants.
The Planning section is responsible for preparing these demonstrations and developing the policies of DAQ.
Special services (ad hoc) - represents DAQ in various regional air quality initiatives and forums including: the
Chesapeake Bay Program, the Mid-Atlantic Regional Air Management Association (MARAMA), the South-Eastern States Air
Regulatory Management (SESARM) and Regional Haze Planning Organization, as well as performing regulatory research
and development. Transportation Conformity (ensuring that transportation projects do not cause air quality
violations) issues are also addressed.
