![]() ![]() Or, a project may result in stormwater that comes from many diffuse sources ( nonpoint sources). ![]() A project may create stormwater runoff that is discharged at a specific location such as a ditch, pipe, or channel ( point sources). This question explores what, if any, type of stormwater discharge will occur as a result of your proposed activity. Pollutants carried by stormwater can also affect recreational uses of water bodies by making them unsafe for wading, swimming, boating, and fishing. Pollution transported by stormwater degrades the quality of drinking water, and damages fisheries and habitats of plants and animals that depend on clean water for survival. If this stormwater runoff is not slowed and captured before it flows into reservoirs, water supplies, lakes, rivers, and wetlands, or it flows over on-site wastewater treatment system locations, it can negatively impact water quality or water treatment and supply systems.įor additional information see also the Stormwater and Urban Stormwater Runoff Facts. When this happens, the water picks up and moves chemicals, nutrients, sediments or other pollutants and debris along with it. Stormwater runoff comes from rain and snowmelt that flows over land or constructed surfaces such as paved streets, sidewalks, parking lots, and rooftops, and that does not seep into the ground. Will storm water discharges be directed to established conveyance systems (runoff and storm drains)? _ NO _ YES Will storm water discharges flow to adjacent properties? _ NO _ YESī. Will the proposed action create storm water discharge, either from point or non-point sources?Ī. ![]() 17, Short EAF (Part 1) Storm Water Discharge Environmental Assessment Form Workbook ![]()
