Standard Practice for Determining the Performance of Oil/Water Separators Subjected to a Sudden Release

Importancia y uso:

5.1 The Clean Water Act promulgated the implementation of water quality standards and contamination limits for a wide range of pollutants including oil and grease. Specifically, the EPA, in 40 CFR Ch. 1, prohibits “the discharges of oil that cause a film or sheen upon or cause discoloration of the surface of the water. . .” Several state and local agencies have adopted this statement in addition to setting concentration limits, that is, 15 mg/L or even 5 mg/L. The purpose of this practice is to evaluate the performance of a separator in regards to the regulations and user requirements when subject to a sudden release. The sudden release may occur in dry weather and local personnel may attempt to hose the contaminated area down or it may occur on a rainy day and enter the separator mixed in with the runoff.

5.2 This practice is not applicable if the influent to a separator is simply runoff from contaminated rainwater. For this case, see Practice D6104.

5.3 This practice is not applicable if the influent to a separator is conveyed by a pumping means.
