National Pollutant Discharge Elimination System (NPDES) Permitting

Sewer Grate Photo

Section 402 of the Clean Water Act establishes the Federal program to regulate the discharge of water pollutants from point sources into waters of the U.S.  In Missouri, this program is under the jurisdiction of the Missouri Department of Natural Resources, while in Kansas it is the responsibility of the Kansas Department of Health and Environment. NPDES permits are frequently required for activities involving Concentrated Animal Feeding Operations (CAFO's), stormwater runoff, sanitary sewer overflows, combined sewer outflows, and wastewater pretreatment.

In March 2003, stricter NPDES Phase II requirements went into effect.  Regarding improvements in storm water quality, the federal mandate requires municipalities to adopt or incorporate policies and procedures to ensure that nonpoint source discharges are managed to minimize environmental pollution.  Numerous forms of contamination will be assessed, including, but not limited to, total solids, inorganic chemical, complex organochemical, and litter.  The requirement extends to almost any property owner, government agency, or business and is expected to result in the complication of residential, industrial, commercial, and public-benefit projects.

Terra Technologies has helped clients through all phases of the NPDES permitting process by writing Storm Water Pollution Prevention Plans (SWPPPs), conducting SWPPP inspections and collecting water quality samples in order to evaluate the concentration of numerous pollutants and to monitor sites for compliance with NPDES requirements.
