To reduce the impact of contaminants in storm water, there are certain businesses that are required to develop SWPPP. One of these business sectors is Construction. The purpose of the SWPPP is to identify potential sources of pollutants and minimize the potential for them to be carried away in storm water discharges. 37 Programs: Instructor Note: A video on hydraulic fracturing is provided at the following Underground Injection Control - Purpose website.
