I • Conduct a field survey of buildings, particularly older buildings, and other industrial areas to 11 locate storm drains from buildings and paved surfaces. Note where these discharge. • During non-stormwater conditions, inspect each storm drain for non-stormwater discharges. Record the locations of all non-stormwater discharges. Include all permitted discharges. • If useful, prepare a map of each area. Show on the map the known location of storm sewers, 1 sanitary sewers, and permitted and unpermitted discharges.Aerial photos may be useful. Check records such as piping schematics to identify known side sewer connections and show these on the map.Consider using smoke, dye,or chemical analysis tests to detect con- nections between two conveyance systems(e.g., process water and stormwater). If desir- able,conduct TV inspections of the storm drains and record the footage on videotape. • Compare the observed locations of connections with the information on the map and revise the map accordingly. Note suspect connections that are inconsistent with the field survey. • Identify all connections to storm sewers or to surface water and take the actions specified above as applicable BMPs.
