The Commissioner of Water Pollution Control is designated as the Stormwater Manger for the city of Cleveland, responsible for overseeing the implementation of the entire Stormwater Management Program (SWMP).
In addition to oversight, the Commissioner heads the city’s Stormwater Steering Committee. The committee is comprised of representatives from various city departments/divisions (Building & Housing, Planning, Law, Public Works, and the Mayor’s Office of Sustainability) that provide support and guidance for the city’s stormwater management efforts and ensures that the city remains in compliance with stormwater regulations.
WPC, as Cleveland’s Stormwater Manager, has to demonstrate compliance with the SWMP by submitting annual reports to the Ohio Environmental Protection Agency.
Stormwater Runoff and the Need to Reduce Its Flow
Stormwater runoff is rainfall or snow melt that flows over the ground surface. It is created when water on roads, driveways, parking lots, rooftops and other paved surfaces does not soak into the ground. Stormwater runoff is the number one cause of stream impairment in urban areas. Large volumes of water are carried to our local streams, wetlands, Lake Erie and the Cuyahoga River and, which can cause flooding and erosion, and wash away important habitat for animals that live in or around waterways.
Stormwater runoff also picks up and carries with it many different pollutants that are found on paved surfaces such as sediment, nitrogen, phosphorus, bacteria, oil and grease, trash, pesticides and metals. These pollutants come from a variety of sources, including pet waste, lawn fertilization, cars, construction sites, illegal dumping and spills, and pesticide application. Researchers have found that as the amount of paved/pervious surfaces in the watershed increases, stream health declines.
Minimum Control Measures
Municipal Separate Storm Sewer Systems (MS4) permittees, such as Cleveland, must develop, implement, and enforce a Stormwater Management Program (SWMP) designed to reduce the discharge of pollutants to the maximum extent practicable to protect water quality and to satisfy the appropriate water quality requirements of the Clean Water Act.
Cleveland’s SWMP explains how the program is run, describes best management practices (BMPs) and measurable goals that are used to address the Six Minimum Control Measures (MCMs) in the permit. Learn more about MCMs.
