Conduct inspections during dry weather periods.
Check the outfall’s dimensions, shape, and component material using the Storm Drain
Characteristic Form.
Characterize and record observations on basic sensory and physical indicators (e.g., odor,
color, oil sheen).
44
NOTE: This information is to accompany the Dry Weather Outfall Inspection Form.
Odor — Most strong odors, especially gasoline, oils, and solvents are likely associated with high responses on the toxicity
screcning test.
Stale sanitary wastewater: sewage
Detergent, perfume: Laundromat or household laundry
Sudiur (“rotten eggs"): industries that discharge sulfide compounds or organics (meat packers, canneries, dairies)
Or! and gas: facilities associated with vehicle maintenance or petroleum product storage (gas stations) or petroleum
