Where to Begin - DEEP's Environmental Permitting Process
(User's Guide to Environmental Permits)

If you plan to conduct activities that may impact the state's natural resources and environment, then you may need one or more environmental permits from the DEEP. 

In addition to individual permits and licenses, the CT DEEP has developed several expedited and short processes to facilitate the permitting of minor activities in its major permit programs. These processes include general permits, Certificates of Permission (COP), and temporary and emergency authorizations.
The department has prepared a series of fact sheets describing each of its permit programs to help permit applicants and others understand the environmental permitting process. The information is designed to answer general questions and provide basic information. You should refer to the appropriate statutes and regulations for the specific regulatory language of the different permit programs. If you have any questions or need further help, please feel free to contact any of the department's staff or our Ombudsman at 860-424-3003.
