What is Stormwater?
Stormwater: The flow of water that results from precipitation that occurs immediately following rainfall or as a result of snowmelt.
When a rainfall event occurs, several things can happen to the precipitation. Some of the precipitation infiltrates into the soil surface, some is taken up by plants, and some is evaporated into the atmosphere. Stormwater is the rest of the precipitation that runs off land surfaces and impervious areas.
Stormwater discharges are generated by precipitation and runoff from land, pavements, building rooftops and other surfaces. These hardened surfaces are called ‘impervious surfaces’ as they do not allow rainfall to infiltrate into the soil surface like natural vegetation, so more of the rainfall becomes stormwater runoff. Stormwater runoff accumulates pollutants such as oil and grease, chemicals, nutrients, metals, and bacteria as it travels across land.
The Village of Granville is a participant in the Ohio EPA Stormwater Protection Program
The Village of Granville is a participant of Ohio Environmental Protection Agency (Ohio EPA) National Pollution Discharge and Elimination System (NPDES) Phase II program. The Phase II regulations, a component of the Clean Water Act, require small municipal separate storm sewer systems in urbanized areas, defined by the census bureau, to develop a Stormwater Management Program and apply for permit coverage. This program is regulated by the Ohio EPA. The goal of this mandate is to control pollutants entering municipal stormwater systems that discharge into receiving waters of the state of Ohio. Municipalities must implement an ongoing comprehensive Stormwater Management Program that addresses each of the six Minimum Control Measures (MCM) described below.
