The Department of Environmental Protection's (DEP) Stormwater Facility Maintenance Program relies on skilled and knowledgeable contractors to perform maintenance on stormwater management facilities. A company that performs maintenance on a stormwater management facility must hold a certificate of attendance from an approved training program. DEP offers a list of all the companies that have completed the required training.

How Can My Company Become Certified To Perform Maintenance in Montgomery County?
Montgomery County regulations require that a company that performs repair or maintenance on a stormwater management facility must:
- Have demonstrated experience in stormwater management facility construction
- Have demonstrated experience in stormwater management facility inspection
- Hold a Certificate of Attendance awarded through a training program approved by DEP
DEP offers a single training every year in the spring. It is not a program or multiple classes. Interested contractors must take the interim certification test, and then plan to attend the annual Stormwater Facility Maintenance Contractor Training class.
A company that performs repair or maintenance on an underground stormwater facility must also have the training and credentials required under applicable state and federal law, including an Oil Operations Permit from the Maryland Department of the Environment and a Confined Space Certification from the federal Occupational Safety and Health Administration (OSHA).
