The National Pollutant Discharge Elimination(NPDES) project is designed to monitor and evaluate point source pollution problems on the Wind River Indian Reservation.

Point source pollution can be described as pollution which comes from a distinct known source or froma discrete, discernible, and confined conveyance (e.g. pipe, ditch, channel, etc.), which discharges waste water into a surface waters on the reservation.  The primary point sources on the reservation are industrial (oilfield water discharges), municipal (sewage lagoons), and mineral hot springs.  As we (WREQC) monitor these point source sites, it will enable the tribes to better identify if any water quality problems exist at the discharge sites.

The Environmental Protection Agency (EPA) has primacy in the State of Wyoming. Therefore, if any of the discharge permittees are out of compliance with effluent standards, compliance schedules, or water quality standards, the EPA will be notified about the violation(s).
