Maryland is home to more than 1,000 industrial facilities, including landfills, auto salvage yards, hazardous waste treatment, storage sites, and various types of manufacturing and processing plants. When it rains or snows, toxic pollution often runs off these facilities and enters nearby waterways and groundwater resources, negatively impacting aquatic life, nearby communities, and drinking water sources.
The problem — known as industrial stormwater pollution — is dire in Maryland. More industrial facilities are being built in the state, and precipitation intensity is increasing more quickly in the Chesapeake Bay region than elsewhere in the United States, threatening public and environmental health. Low-income people and communities of color are at heightened risk.
The Maryland Department of the Environment (MDE) requires industrial facilities not covered by individual permits to obtain a general permit for industrial stormwater. This permit supports Maryland's commitment to restoring the Bay by 2025 by obligating facilities to take pollution control measures, such as proper storage of chemicals and facility maintenance.
Whether the permit accomplishes these goals largely depends on how well it is enforced.
Without adequate enforcement, industrial facilities are free to run afoul of the …
Dirty, polluted stormwater that runs off of industrial sites when it rains is a major cause of pollution to Maryland’s streams and rivers, and ultimately to the Chesapeake Bay. Maryland is home to thousands of such industrial sites, all of which are required by law to obtain a stormwater discharge permit from the Maryland Department of the Environment (MDE) to prevent pollution and protect public and environmental health.
Unfortunately, many of these sites do not have a permit. For example, our research in one small area of Anne Arundel County found that only four out of 12 industrial sites possessed a current permit. Of the industrial sites that hold a permit, many are not in compliance with the permit requirements. Between 2017 and 2020, MDE conducted …
As Maryland heads into the final stretch of a collective effort to clean up the Chesapeake Bay, it has inexplicably passed over its best opportunity in years to modernize regulation of industrial stormwater — rain and snow that collects toxic pollution as it runs off factories, warehouses, scrap metal dealers, and other industrial sites.
Earlier this year, Maryland released a proposed revision of its general water pollution permit, which limits the type and amount of pollutants that facilities can discharge into public waters and sets monitoring and reporting requirements to protect public and environmental health.
Unfortunately, the state missed an important opportunity to bring stormwater regulation from the last century into the present — but it’s not too late to change course.
