Debris and Oil
1. Remove two (2) 15 inch diameter metal covers to Trash Shelf and Pretreatment Chamber
2. If oil is present in Pretreatment Chamber, measure its depth. Clean liquids from system
3. Remove all debris from nearby curbing, Curb Inlet, Trash Shelf and Pretreatment Chamber and any oil with Vacuum system, basket or net if any present
4. Return metal covers prior to departing site
Note: Water in Pretreatment Chamber can appear black like oil due to the dark body of the surrounding structure. Oil appears
darker than water in the system and may be accompanied by debris (e.g. Styrofoam, etc.) with obvious signs of oil stains.
The depth of oil can be measured with an oil/water interface probe, a stadia rod with water phylic paste,
a coliwasa, or by simply collecting a representative sample with a jar attached to a rod.
