MS4 employees must practice illicit discharge detection out in the field. This pocket sized reference booklet goes anywhere and helps the employee remember what to look for both at the source and at the outfall. Photo examples illustrate the signs of past discharges, suspect activities and midnight dumping. The booklet includes tear out Observation Report forms which can be used in the field to document an observed discharge for later submission to the stormwater authority. Five booklets are included in each "IDDE - a grate concern" training kit; additional copies are available in packs of 10.
