The Water and Science Administration (WSA) is the regulatory agency responsible for managing the State’s water resources. Within WSA, the Stormwater, Dam Safety, and Flood Management (SDSFM) Program oversees State programs and administers permits that direct local counties, cities, and towns to protect waters from pollution created by stormwater runoff. The erosion and sediment control programs regulate new construction activities to minimize suspended sediment (soil particles carried by water) leaving construction sites and entering local waterways.
When rainfall reaches exposed soil, suspended sediment may be transported and deposited in streams at a level beyond natural processes. This can reduce stream channel capacity which can lead to additional erosion and flooding downstream. The frequency and intensity of storms that contribute to flooding are expected to increase due to climate change, making proper controls even more critically important in the future. Sediment transported by stormwater can also negatively impact water quality by blocking sunlight, inhibiting plant growth, damaging habitat for aquatic animals, and increasing the load of nutrients such as phosphorus and nitrogen that act as pollutants when present in excessive amounts.
Erosion and sediment control practices may be used to manage stormwater runoff and minimize its potential for pollution, leading to greater climate resiliency in the State. The Code of Maryland Regulations (COMAR) 26.17.01 provides the Administration with the responsibility to establish policies, procedures, standards, and criteria relating to erosion and sediment control. Under this authority, the Administration requires erosion and sediment control plans to be reviewed and approved for earth moving activity that disturbs 5,000 square feet or more of land area or 100 cubic yards or more of soil. However, the Department may authorize (delegate) local governments to administer erosion and sediment control programs to inspect and enforce active construction in their jurisdictions. Local programs may establish stricter requirements than the State’s as needed. For more information on the history of sediment and erosion control regulations in Maryland, click here.
Anyone planning construction activity or wishing to submit a construction-related complaint should first consult with their local jurisdiction.
Please see this list of delegated jurisdictions to check if you are in an area where erosion and sediment control enforcement authority has been delegated by the Department. If your area is not on this list, please contact the Department’s Compliance Program for assistance with submitting a construction-related complaint. For information on planning construction projects disturbing one or more acres, please contact the Wastewater Permits Program for information on the General Permit for Stormwater Associated with Construction Activity. This requirement is in addition to local erosion and sediment control plan approval processes and any local codes for grading and building, so the Department strongly recommends you also contact your local jurisdiction. Finally, if you are performing construction on a State or federal property, please visit the Department’s Plan Review division for more information.
Erosion and sediment control plans are developed to protect water resources from sediment pollution carried by runoff associated with active land development and redevelopment activities. By retaining soil on site, sediment and nutrients are prevented from running off disturbed area and polluting streams and other surface waters. Maintaining quality runoff from construction activities is critical to Maryland’s effort to reduce the levels of nutrients and sediment in the Chesapeake Bay.

Frequently Asked Questions for the Construction Industry
This document provides answers to questions frequently asked by individuals in the construction industry. If the answer to your questions is not included, please contact your local jurisdiction (see above).

The Department authorizes local governments to administer a program to inspect and enforce active construction in their jurisdiction. These programs are reviewed by the Department every two years to ensure they are conducted in accordance with State law and regulation including COMAR 26.17.01 and any updates. The below information is provided to assist delegated authorities in maintaining programs that comply with the latest regulations and guidance.
Each authority must adopt a local ordinance that establishes a process for the review of proposed construction plans and enables them to inspect active construction and enforce requirements as necessary. The authority must maintain a Department-approved list of major field modifications that require the approval of the local plan approval authority, typically a Soil Conservation District, and minor modifications that may be made in the field with the supervision of an inspector representing the delegated authority. All controls must conform to the standards and specifications outlined in the State’s 2011 manual. A standard plan for small development projects may also be developed. Through these efforts along with maintaining ongoing communication with the Department, delegated authorities ensure proper erosion and sediment control to protect waters throughout Maryland.
The Maryland Department of the Environment has developed the following guidance to ensure the quality of inspection reports is maintained as effective documentation of site conditions:Generating Quality Inspection Reports for Erosion and Sediment Control NEW!
The following is a recording of the Deparment's presentation of the new guidance and a Q&A session on April 25, 2024:
