SIGNIFICANCE AND USE
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.
SCOPE
1.1 This practice describes the testing procedure, any necessary related apparatus, and the sampling technique to be used in determining the performance characteristics of an oil/water separator subjected to the sudden release of a relatively large quantity of hydrocarbons that may appear in its influent in pure form or at high concentration.  
1.2 This practice does not address the determination of the performance characteristics of an oil/water separator subjected to surface run-off resulting from rain water draining from improved or unimproved land. In this case, refer to Practice D6104.  
1.3 This practice does not address the determination of the performance characteristics of an oil/water separator subjected to a mechanically emulsified influent such as provided by a pump.  
1.4 This practice does not investigate the ability of the separator to handle debris or suspended solids, that is, grit or tree leaves.  
1.5 While the effluent may meet code requirements for total oil and grease content, this practice does not address the presence of soluble organics, that is, benzene, toluene, ethyl-benzene, and xylene (BTEXs) that may be detected in the effluent. It also does not make any provisions for the effects of detergents, surfactants, soaps or any water soluble matter (that is, salts) or any portion of an essentially insoluble matter that may be found in solution on separation. (Effects of certain water soluble chemicals or solids may be investigated by adding them to the water at predetermined constant concentrations.)  
1.6 In order to estimate the effect of water temperature on the performance of the separator, the tests described in this practice must be performed at two water temperatures. The selected temperatures must be at least 10°C (18°F) apart, with the temperature ranging from a minimum of 0°C (32°F) to a maximum of 50°C (122°F).  
1.7 This practice does not make any provisions for the variation of pH or temperature during a test run. Refer to Appendix X1 for further detail.  
1.8 This practice can be used with a variety of hydrocarbons. It adopts No. 2 fuel oil with a density2 of 845 kg/m3 (52.73 lbm/ft3) and a viscosity2 of 1.9 to 4.1 centistokes at 40°C (104°F) and SAE 90 lubricating oil with a density (See SAE J313) of 930 kg/m3 (58 lbm/ft3) at 15.5°C (60°F) and a viscosity (see SAE J306) of 13.5 to  
Note 1: No extrapolation outside the range of the tested influent or effluent oil concentrations is allowed as performance may not be linear. Hence, to establish performance at a higher or lower concentration, the separator shall be tested for that specific condition. In addition, linearity must be established prior to using linear interpolation.  
1.9 Since regulations are based on effluent total hydrocarbon content, this practice does not set forth any lower limits on oil particle size for the evaluation of ...

The purpose of this practice is to evaluate the performance of a separator in regards to the regulations and user requirements.  
5.2 Another purpose of this practice is to establish that a separator containing oil at its rated capacity would still be capable of meeting the above criteria when subjected to run-off.  
5.3 This practice is not applicable if the influent to a separator contained a sudden release as much higher concentrations would be expected. For this case, see Practice D6157.  
5.4 This practice is not applicable if the influent to a separator is conveyed by a pumping means.  
5.5 The data generated in this method is valid for the separators tested only. The results of these tests may be extrapolated to smaller or larger size separators provided that applicable geometric and dynamic similitude are maintained. Where sound engineering method limits the use of extrapolation, that size unit must be subjected to testing.  
5.6 The flow rate for all the tests must equal the manufacturer's total rated flow for the given separator at a given influent contamination level and for the selected effluent peak contamination concentration.
