Rio Hondo Land and Cattle Company (“Rio Hondo”) petitioned the Environmental Appeals Board (“Board”) to review a National Pollutant Discharge Elimination System Permit (“Permit”) that the United States Environmental Protection Agency Region 6 (“Region”) issued to the City of Ruidoso Downs and Village of Ruidoso Wastewater Treatment Plant (collectively “Ruidoso”). The Permit authorizes discharges from the Ruidoso wastewater treatment plant into the Rio Ruidoso in Lincoln County, New Mexico.
