​​​​CEIR Introduction

The Maryland Department of Natural Resources (DNR) Power Plant Research Program (PPRP) evaluates how the design, construction, and operation of power plants and transmission lines affect Maryland’s environmental, socioeconomic, and cultural resources. The Maryland Power Plant Siting Act of 1971 directs PPRP to prepare a biennial Cumulative Environmental Impact Report (CEIR). The intent of the CEIR is to assemble and summarize information regarding the impacts of electric power generation and transmission on Maryland’s natural resources, cultural foundation, and economic situation.
