DENR fines Rapid City for surface water violations


PIERRE, S.D. —  The South Dakota Department of Environment and Natural Resources (DENR) has fined the City of Rapid City $8,045 for Surface Water Discharge Permit violations at its regional recycling and municipal landfill facility (RALF) located south of Rapid City.

The RALF discharges effluent, which is liquid waste or waste water, into an unnamed tributary of Rapid Creek using a state-issued Surface Water Discharge Permit.

Between May 2015 and February 2020, the city reported violations of its permit limits for ammonia, total recoverable selenium, total suspended solids, pH, and total petroleum hydrocarbons.

For the violation, Rapid City must now:

  • verbally report any daily maximum violations, 30-day average effluent violations, or whole effluent toxicity violations within 24 hours and submit an engineering report identifying the cause of such violations along with the steps taken to correct them
  • submit a detailed map of the facility, including information on site topography, drainage areas, storm water discharge points, control measures, and other areas of concern
  • by March 1, 2021, the city must also submit a schedule for completing any planned improvements necessary to ensure permit compliance

More information about DENRs Surface Water Discharge permitting program can be found here.

All fines and penalties are deposited in the state Regulated Substance Response Fund, which is used to respond to environment emergencies.

AUTHORS NOTE: The Rapid City RALF Facility is not the same as the Water Reclamation Facility.
