Illicit discharges are nonstormwater discharges that are not allowed under the National Pollutant Discharge Elimination System (NPDES). Sanitary wastewater, car wash wastewaters, improper oil or radiator flushing disposal, laundry wastewaters, and improper disposal of auto and household toxics are examples of illicit discharges that can be the source of pollution to Mountain Park' stormwater drainage system and local streams. Mountain Park staff members are trained to recognize and report these discharges to the Department of Environment and Natural Resources for enforcement action. You can help too by reporting these types of discharges to the City of Mountain Park.
