A hurricane is defined as runoff or precipitation that flows over the ground without being absorbed by the soil. Water traps other materials such as debris, chemicals, mud, and other contaminants along the way, and once it reaches a body of water, it carries those contaminants with it. Even small amounts of chemicals, sludge, and oil will degrade water quality if left untreated.
The EPA's National Pollutant Removal System (NPDES) rainwater program regulates this runoff from individual municipal storms (MS4), construction and industrial sites. Disposal is a point resource and this site and community require permission to remove it. Such regulations prevent rainwater from these sites and communities from drifting pollutants into water bodies. Some companies help you to maintain and service your storm water maintenance.

25 countries implement NPDES, but the rest have their own local laws based on EPA regulations. NPDES also applies to tribal areas and regions. NPDES requires construction sites, industrial sites, and municipalities to apply for permits, and site operators with maintenance or more must have permits for construction. The Building Permit (CGP) requires the site and its operators to develop a rainwater prevention plan to prevent erosion and mud and pollutants from entering the water body.
Industrial sites must meet more stringent rainwater management standards. A variety of material processing and storage areas fall under the industrial site category, including heavy production, coal and mineral extraction, hazardous waste treatment and storage, landfill, scrap, steam power plants, transport equipment performing maintenance, sewerage and light treatment.
