Regulated facilities reasonably expected to discharge oil

How do I determine if my facility could reasonably discharge oil into or upon navigable waters or adjoining shorelines?

This determination is based solely upon a consideration of the geographical and locational aspects of the facility.  The location of the facility must be considered in relation to streams, ponds and ditches (perennial or intermittent), storm or sanitary sewers, wetlands, mudflats, sandflats, or other navigable waters.  The distance to navigable waters, volume of material stored, worse case weather conditions, drainage patterns, land contours, soil conditions, etc., must also be taken into account.
