Oil in water discharges from industrial and other facilities are governed by a variety of federal, state and local laws. MSR equipment can be very helpful in stormwater quality mitigation. The basic law covering discharges is the Clean Water Act (CWA). Permits for discharge are required and any discharges other than those allowed by permit are illegal. Although the Clean Water Act (CWA) was enacted primarily to control discharges from sanitary sewer and industrial plants, it also governs other discharges of water containing petroleum and other hydrocarbons into water. Most states and localities require discharges to contain 15 ppm or less oil and grease, based on a 24 hour composite sample. This requirement is based on the CWA requirement for “no sheen”. Oil and grease may include petroleum hydrocarbons as well as animal and vegetable oils. MSR equipment may also be used to remove oil for processing rainwater for rainwater harvesting. Stormwater discharges were covered under the CWA but not required to have permits under the system until 1990. “Stormwater discharges” refer to discharges consisting entirely of rainwater runoff, snowmelt runoff, or surface runoff and drainage. Waters that do not meet this definition are not covered by these regulations. These rules specify that facilities with storm water discharges from “areas containing raw materials, intermediate products, finished products, by-product, or waste product located on site” will require a permit.
