Maine Transmission Siting (8-ME-a)

In Maine, a developer may need to obtain a Site Location of Development Permit from the Maine Department of Environmental Protection (MDEP) prior to constructing a transmission line of 100 kilovolts (kV) or more pursuant to the state’s Site Location Development Act. 38 M.R.S. § 488.

The Site Location of Development Act tasks state agencies with controlling the location of development of “state or regional significance that has a substantial affect on the local environment in order to insure that such development has minimal impact on the natural environment and the health, safety, and general welfare of the people.”38 M.R.S. § 481.

A person may not construct or operate any development of state or regional significance that may substantially affect the environment without first obtaining a Site Location of Development Permit from the Maine Department of Environmental Protection (MDEP). 38 M.R.S. § 483-A. Electric transmission lines of 100 kV or more are subject to the Site Location of Development Act as a development of state or regional significance that may substantially affect the environment. 38 M.R.S. § 488.

MDEP regulates site development pursuant to Site Location Development Act and Maine – 06-096-372 ME. CODE R. et seq., Department of Environmental Protection – Policies and Procedures Under the Site Location Law.


Transmission Siting Process

8-ME-a.1 to 8-ME-a.2 – Contact MDEP Regional Office

The developer should contact the MDEP regional office at the outset of the project. Generally, the MDEP and the developer must hold a pre-application meeting regarding any new Site Location of Development Permit Application (Application). The MDEP also recommends pre-application meetings for all major amendments to existing projects. The MDEP may waive pre-application meeting requirements at its discretion.

The purpose of the pre-application meeting is to help the developer understand the Application review process, identify particular areas of concern, and exchange information before commitment to a final design. This meeting may lead to a substantial reduction in processing time. For information about arranging a pre-application meeting, the developer should contact the appropriate regional office. – Site Location of Development Permit Application, at 1.
