Delaware's Air Quality Regulations require operators of stationary generators to register their equipment with the Division of Air Quality, regardless of whether the equipment requires a permit to operate. This regulation aims to ensure that air emissions from new and existing stationary generators do not cause or contribute to air quality problems in Delaware.
Emergency generators play a crucial role in providing electricity during grid failures, and they are used in hospitals, healthcare facilities, and other critical infrastructure. However, fossil fuel-fired generators powered by reciprocating internal combustion engines emit high rates of air contaminants, contributing to ground-level ozone and fine particulate matter formation.
All non-emergency generators, regardless of size, require a Regulation 1102 permit. Emergency generators with a capacity greater than 450kw also require a permit. To obtain a permit, owners must complete specific forms, including AQM-1, AQM-2, AQM-3.3, and AQM-5, and submit them to the Division of Air Quality along with the required permit fees.
The Environmental Protection Agency (EPA) has published Federal Stationary Engine Regulations that include New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants related to internal combustion engines.
