Solid Waste Management in Maryland

Program Summary:

MDE's Solid Waste Program (SWP) is responsible for assuring that society's domestic, commercial, and non-hazardous industrial solid waste is handled properly. Improper handling of these wastes can pose direct threats to both public health and Maryland's natural resources, particularly water resources. Since 1914, Maryland has had laws requiring solid waste be handled in a manner that minimizes the risk posed to public health and the environment. The impact caused by poor waste disposal practices include:

  • 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 (SWA) Facilities

A Refuse Disposal (RD) Permit is required for the installation, alteration, or extension of a 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. SWA facilities, which are regulated by a 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

For a complete list of permitted SWA facilities, see the Permitted Facilities page.

Natural Wood Waste Recycling (NWWR) Facilities

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 more information about NWWR, see the Natural Wood Waste Recycling page.


Composting Facilities

Composting of 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 rates and flies.

Composting Operation Fact Sheet - This two-part fact sheet developed by the Land and Water Management Administrations provides guidance regarding the various types of MDE permits that may be required for commercial, governmental or experimental composting operations.

For more information about composting, see the Organics Diversion and Composting Page.

Proposed Compost Facility Regulations

The Maryland Department of the Environment proposes to adopt new regulatory requirements for composting facilities, under COMAR 26.04.11:

Land Regulations - This page provides information on all Land Management Administration regulations including those proposed, and in-development.

Notice of Proposed Action - (1/10/2014) Maryland Register, Volume 41, Issue 1

Notice of Proposed Action New! - (12/12/2014) Maryland Register, Volume 41, Issue 25
Comments may be sent to Kaley Laleker, Waste Diversion and Utilization Program, Land Management Administrtaion, Maryland Department of the Environment, 1800 Washington Blvd., Suite 610, Baltimore, MD 21230-1719, or call 410-537-3314, or email to, or fax to 410-537-3321. Comments will be accepted through January 12, 2015. A public hearing has not been scheduled.

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 Management 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.
