Connecticut Siting Council

The Connecticut Siting Council (The Council) was first established as the Power Facility Evaluation Council in 1972 following the passage of the Public Utility Environmental Standards Act. In 1981, it became known as the Connecticut Siting Council with the passage of PA 81-369, which expanded the Council’s original jurisdiction over the siting of power facilities and transmission lines to include hazardous waste facilities. The Council’s jurisdiction has since been extended to include various other forms of infrastructure including telecommunications sites.


The Council is responsible for:

  • balancing the need for adequate and reliable public utility services at the lowest reasonable cost to consumers with the need to protect the environment and ecology of the state and to minimize damage to scenic, historic, and recreational values;
  • providing environmental standards for the location, design, construction, and operation of public utility facilities that are at least as stringent as federal environmental standards and that are sufficient to assure the welfare and protection of the people of Connecticut;
  • encouraging research to develop new and improved methods of generating, storing, and transmitting electricity and fuel and of transmitting and receiving television and telecommunications signals with minimal damage to the environment;
  • promoting the sharing of telecommunications towers in order to avoid their unnecessary proliferation; and
  • requiring annual forecasts of the demand for electricity together with the planning for facilities needed to supply the predicted demand.


The Council confirms compliance with its certificates and orders through detailed development and management plans and field investigations. Development and management plans are professionally engineered documents that may consist of designs, site plans, construction schedules, and site inspection reports.

Enforcement of Council orders is performed by the Connecticut Attorney General’s office.


The Council has specific jurisdiction over the statutorily defined facilities listed below.

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.
