This manual guides Navy areas in developing and implementing their Spill Prevention, Control, and Countermeasure plan (SPCC Plan) for oil and hazardous substances (HS). This document is required by the Environmental Protection Agency (EPA) Part 40 of the Code of Federal Regulation, Section 112 (20 CFR 112), the Oil Pollution Prevention regulation, and OPNAVINST 5090.1B, for oil area meeting the criteria in 40 CFR 112. Spill control measures are required for hazardous waste (HW) storage areas regulated by either 40 CFR 264 or 40 CFR 265. Additionally, some spill control measures are required for underground storage tanks (UST) regulated by 40 CFR 280. HW storage areas, not specifically regulated by the above referenced regulations, do not have regulated spill control requirements; however, it is considered best engineering practice to have spill control measures at all HS storage areas. Therefore, it is recommended that all HS storage areas be included in Navy SPCC plans. For overseas locations please refer to OEBGD/FGS criteria for spill prevention guidance.
