Air Permitting

A variety of air quality permits are issued to ensure that emissions from new, modified or existing sources of air pollution do not harm public health or cause significant degradation to air quality.  These permits contain requirements to limit emissions either through control technologies or operational limitations and a means to assure compliance.  The criteria for issuing permits and for defining permit requirements for new or modified facilities are specified in regulations.  The DEEP air permit staff who perform the permit reviews and administer the program are available to assist you and answer questions.

 

All permits are issued in accordance with applicable Connecticut and Federal regulations and in accordance with our mission and responsibility to the citizens of Connecticut to protect the environment and public health.
