In May 2013, the United States District Court for the District of Maryland entered a Consent Decree, resolving three complaints filed by Maryland Department of the Environment (“MDE”) against GenOn Maryland Ash Management, LLC and GenOn Mid-Atlantic, LLC. (Note that GenOn formerly operated as “Mirant” and currently operates as “NRG Energy.”)
The complaints alleged multiple violations of the federal Clean Water Act at three coal combustion waste landfills in Maryland: the Brandywine Landfill in Prince George’s County, the Faulkner Landfill in Charles County, and the Westland Landfill in Montgomery County. The map below shows the locations of these landfills.

Coal combustion waste ("CCW"), often referred to as “coal ash,” is the waste product from burning coal in power plants and can contain heavy metals and other toxic materials. When CCW is exposed to storm water or groundwater, it forms leachate. If not properly controlled, leachate can transport CCW pollutants to surface waters and groundwater, where it can adversely impact human health and the environment.
In 2009, environmental organizations Defenders of Wildlife, Sierra Club, Patuxent Riverkeeper, and Chesapeake Climate Action Network, represented by the University of Maryland Environmental Law Clinic and the Environmental Integrity Project, sent a Notice of Intent to Sue letter to GenOn regarding alleged Clean Water Act violations at the Brandywine Landfill. This letter triggered MDE’s filing of its federal complaint regarding the Brandywine Landfill. After the complaint was filed, the environmental organizations successfully intervened in MDE’s federal suit and participated in the settlement process. MDE later filed additional complaints alleging Clean Water Act violations at GenOn’s Faulkner and Westland CCW landfills.
The Consent Decree, obligates GenOn to take the following actions:
In addition, the Consent Decree requires MDE to draft updated Clean Water Act permits for each of the landfills. These permits will contain water quality based effluent limitations, limitations based on Best Available Technology, limitations for acute whole effluent toxicity, and, if necessary, monitoring requirements for chronic whole effluent toxicity.
Furthermore, the Consent Decree requires MDE to provide the environmental organizations which intervened with copies of many of GenOn’s submissions and MDE’s determinations. Throughout the implementation of the Consent Decree, the Environmental Law Clinic will post these documents and related communications to this webpage.
Public documents related to the implementation of the Consent Decree are available below. This list was last updated on August 26, 2013.
