• pollution of groundwater, which many Marylanders rely on for drinking water supplies;
• pollution of surface water, with the potential for impacting drinking​ water supplies of many of the large municipalities in Maryland (e.g. Baltimore City); and,
• health nuisances such as odor, rats, flies, and mosquitoes.

 

Solid Waste Acceptance Facilities

MDE regulates Solid Waste Acceptance (SWA) facilities to ensure the proper disposal of solid waste in an environmentally acceptable manner while protecting public health and the environment, including surface and groundwater. A Refuse Disposal (RD) Permit is required for the installation, alteration, or extension of an SWA facility. The RD Permit regulates the design, construction, operation, and monitoring of such facilities to minimize the impact on public health and the environment. Municipal, rubble, and some industrial waste landfills are required to have liners and leachate collection systems that facilitate the collection of leachate and prevent migration of pollutants out of the landfill to adjacent subsurface soil, groundwater, and surface water. (The term leachate is used to describe the liquid formed when precipitation soaks into landfill waste and migrates downward through waste due to gravity. As liquids move through the waste, they may extract substances leaching out of the waste - hence the term leachate) With some exceptions, processing and transfer activities are required to be conducted in an enclosed building to control odor, dust, noise, and the like. For a complete list of permitted SWA facilities, see the Permitted Facilities page.

SWA facilities, which are regulated by an RD Permit, include:

• Municipal landfills
• Rubble [construction and demolition (C&D) debris] landfills
• Non-hazardous industrial waste landfills
• Land clearing debris landfills
• Waste-to-energy facilities
• Municipal incinerators
• Special medical waste incinerators
• Special medical waste processing facilities
• Solid waste processing facilities
• Solid waste transfer stations.
  

PFAS Monitoring and Reporting Requirement​

As of July 1, 2024, the Department will require all facilities conducting monitoring regulated under Code of Maryland Regulations (COMAR) 26.04.07.09, 26.04.07.17, 26.04.07.20 and/or 40 CFR Part 258 to analyze for PFOA, PFOS, PFHxS, PFNA, PFBS, and HFPO-DA (commonly referred to as a GenX Chemical). The risk posed by exposure to PFAS is an emerging and evolving national concern.  For more information about this change, please see the documents below:

Natural Wood Waste Recycling Facilities

An NWWR Facility is a facility that accepts natural wood waste such as tree stumps and limbs, brush, root mats, logs, leaves, grass clippings, unadulterated wood wastes, and other natural vegetative materials that are generated when land is cleared for construction purposes. These facilities produce a variety of products including wood chips, mulch, compost, and firewood, which may be sold to consumers. These facilities are valued because they prevent natural wood waste from entering the landfill and make useful products from such waste. Recycling natural wood waste saves valuable space, thereby extending the life of landfills in Maryland. An individual or general NWWR Facility Permit is required for persons constructing and operating such a facility.  For a complete list of permitted NWWR facilities, see the Permitted Facilities page.  

Natural Wood Waste Fact Sheet - A fact sheet concerning the NWWR regulations.

Composting Facilities

Composting organic material can be a useful way to recycle materials that would otherwise end up in a landfill. Larger-scale commercial, governmental, or cooperative composting activities can potentially have negative environmental impacts such as water pollution, the risk of fire, and the development of significant health nuisances such as odor and the attraction of disease vectors such as rats and flies.  For more information on composting of materials other than NWW, see MDE's Organics Diversion and Composting ​page.

Hazardous Waste

Hazardous Waste may be produced as a by-product of certain manufacturing operations. In addition, many commercial chemical products are regulated as hazardous waste once they are discarded or intended to be discarded. The Hazardous Waste Program of the Maryland Department of the Environment (MDE) is responsible for the regulation of hazardous waste in Maryland.

For additional information or questions, go to the Hazardous Waste web page or contact Ed Hammerberg by email or phone at 410-537-3314. ​

Regulation of the Open Burning of Solid Waste

Open burn permits issued by the local health officer can help to address air pollution, nuisance, and public safety concerns when all applicable laws and regulations are followed. The Land and Materials Administration, with input from the Air and Radiation Management Administration, has put together guidance in an effort to clarify the appropriate application of open burning regulations. 

Open Burning Fact Sheet ​ - This fact sheet describes the regulatory requirements and provides examples of when materials that are solid waste can and can't be burned.
