New Source Review - Air Emission Source
General Info - Statewide License
Portions of Maryland have been designated as ozone non-attainment areas, which means that ozone levels in the ambient air occasionally exceed federal air quality standards. Air is considered unhealthful to breathe when federal air quality standards are exceeded. Therefore, any new major stationary source that will discharge significant amounts of volatile organic compounds (VOCs), oxides of nitrogen (NOx) or fine particulate matter (PM – 2.5) must obtain a New Source Review (NSR) approval prior to construction.
