SPCC for Antonini Enterprises Lathrop Facility need to be pumped out and the leak within the tank will be remediated by an appropriate tank contractor prior to reuse. (iii) Diked area inspection and drainage of rainwater 112.7(e)(2) Bulk storage tanks(onshore);(excluding production facilities). (iii)Drainage areas of rainwater from the diked area into a storm drain or an effluent discharge that empties into an open water course, lake or pond and bypassing the in-plant treatment system may be Acceptable if., (A) The bypass valve is normally sealed closed (B) Inspection of the runoff rain water ensures compliance with applicable water quality standards and will not cause a harmful discharge as defined in 40 CFR part 110 (C) The bypass valve is opened and resealed following drainage under responsible supervision. (D)Adequate records are kept of such events. Note: This section should include a detailed discussion of the inspection and drainage procedures used for diked areas and how drainage is documented (e.g., checklist noting the appearance of the water, time of valve opening, time of valve closing, signature of inspectors, etc.). This section should also include a discussion of an alternate method of drainage to be employed if an oil sheen or oil accumulation is observed. In the event that one or both of the stormwater drains are required to be opened in Stormwater Retention Ponds 1 or 2, the storm water will be inspected prior to discharge. Any evidence of product sheen (oil and grease) should be retained on-site through the use of sorbent booms, thereby preventing this material from entering the City of Lathrop Stormwater Collection System. Opening of the storm drain inlets to the collection system require prior notification and coordination with the City of Lathrop. (iv) Corrosion protection of buried metallic storage tanks: 112.7(e)(2) Bulk storage tanks (onshore); (excluding production facilities). (iv) Buried metallic storage tanks represent a potential for undetected spills. A new buried installation should be protected from corrosion by coatings, cathodic protection or other effective methods compatible with local soil conditions. Such buried tanks should at least be subjected to regular pressure testing. Note: Underground storage tanks for purposes of SPCC must be completely buried, unlike "underground storage tanks"in EPA's UST program, which may be partially buried. There are no underground storage tanks at this facility. All piping is aboveground and can be visually inspected. (v) Corrosion protection of partially buried metallic tanks: 112.7(e)(2) Bulk storage tanks (onshore); (excluding production facilities). (v) Partially buried metallic tanks for the storage of oil should be avoided, unless the buried section of the shell is adequately coated, since partial burial in damp earth can cause rapid corrosion of metallic surfaces, especially at the earthlair interface. There are no underground storage tanks associated with this facility. -13-
