Stormwater is defined as runoff or precipitation that flows over land without being absorbed into the ground. The water picks up other materials along the way, such as debris, chemicals, sediment, and other pollutants, and once it reaches a body of water, it will take these pollutants with it.
Even small amounts of chemicals, sediment, and oils will affect the quality of the water, if not treated. Hence during construction, it is important to take stormwater pollution prevention plans from a professional service provider like opting for assistance from https://pacificcoastcivil.com/low-impact-development-solutions could be beneficial.

The EPA's National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates this runoff from municipal separate storm systems (MS4s), construction, and industrial sites.
Discharges are point sources, and these sites and municipalities need a permit to discharge. Such regulation prevents stormwater from such sites and municipalities from washing pollutants into bodies of water.
NPDES requires that construction, industrial sites, and municipalities apply for permits, and for construction, operators of sites of an acre or larger must have a permit.
The Construction General Permit (CGP) requires that a site and its operator develop stormwater prevention plans to prevent erosion from occurring and sediment and pollutants from reaching a body of water
Industrial sites need to meet stricter standards for stormwater management. Various material handling and storage fields fall under the category of an industrial site, and these include heavy manufacturing, coal and mineral mining, hazardous waste treatment and storage, landfills, metal scrap yards, steam electric power plants, transportation facilities that do maintenance, sewage treatment, and light manufacturing.
