All car washes, truck washes, garages, service stations, car and truck maintenance facilities, fabricators, utility equipment shops and other facilities (as determined by the WCSS) that have sources of sand, soil and oil shall install effective sand, soil and oil traps, interceptors and/or oil/water separators. These systems shall be sized to effectively remove sand, soil and oil at the expected flow rates. These systems shall be, at the user’s expense, cleaned or pumped on a regular basis to prevent impact upon the wastewater collection and treatment systems. Users whose systems are deemed to be ineffective by the WCSS shall be asked to change the cleaning frequency, or to increase the size of the system. Owners or operators of washing facilities will be required to prevent the inflow of detergents and rainwater into the wastewater collection system. Oil/water separator installations shall be required at facilities that accumulate petroleum oils and greases and at facilities deemed necessary by the WCSS.
