The amount of sorbent to be added to the CDS separation chamber can be determined if sufficient knfarmatian is knovrn about the caneentration of oil and grease in the runoff. Frequently the actual concentrations of oil and grease are too variable and the amount to be added and frequency of cleaning 4vill be determined by periodic observation of the sorbent. As an initial application, CDS recommends that approximately 4 to 8 pounds of sorbent material be added to the separation chamber of the CDS units per acre of parking lot ar road surface per year. Typically this amount of sorbent results in a '/~ inch to one ~1"~ inch depth of sorbent material on the liquid surface of the separation chamber. The oik and grease loading of the sorbent material should be observed after major storm events. Oil Sarbent material may also be furnished in pillauz ar boom canfiguratians. The sorbent material should be replaced ~n~hen it is fully discolored by skimming the sorbent from the surface. The sorbent may require disposal as a special or hazardous waste, but '+,^rill depend on local and state regukatary requirements.
