CFR 112.7(b)Plan failed to include a description of potential equipment failure or provide equivalence.The SPCC plan states that Requesting an additional discharge predictions are included in Table 4.The SPCC plan also states that because of the facility's containment structures,a major 60 days while being type of equipment failure leading to discharge is unlikely and that in the event of a discharge that escapes any secondary reviewed and updated containment,spill kits will be on hand that will include absorbent material,booms,and pads.Table 4 of the SPCC plan titled"Potential by Engineering Discharge Predictions"has five columns,"#of containers","Volume(gal)","Contents","Storage Area"and"Spill Prediction".The spill Department. prediction states that it will be within secondary containment.A prediction of the direction,rate of flow and total quantity of oil that could be discharged from the facility as result of each type of major equipment failure.Secondary containment for the tanks is 611 described as being as being a wall around the tanks,but the tanks are described as being double walled by the facility.(b)Where Oen experience indicates a reasonable potential for equipment failure(such as loading or unloading equipment,tank overflow,rupture,or P leakage,or any other equipment known to be a source of a discharge),include in your Plan a prediction of the direction,rate of flow, and total quantity of oil which could be discharged from the facility as a result of each type of major equipment failure.The SPCC plan should address the direction,rate of flow,and total quantity of oil which could be discharged from the facility as a result of each type of major equipment failure such as such as loading or unloading equipment,tank overflow,rupture,or leakage,or any other equipment known to be a source of a discharge.This is a Class II violation. CFR 112.7(c)Plan failed to include secondary containment,diversionary structures,or equip to prevent discharge.The facility has Requesting an additional buried piping and general secondary containment for the piping is not discussed.Provide appropriate containment and/or 60 days while being diversionary structures or equipment to prevent a discharge as described in§112.1(b),except as provided in paragraph(k)of this reviewed and updated section for qualified oil-filled operational equipment,and except as provided in§112.9(d)(3)for flowlines and intra-facility gathering by Engineering lines at an oil production facility.The entire containment system,including walls and floor,must be capable of containing oil and must Department. be constructed so that any discharge from a primary containment system,such as a tank,will not escape the containment system before cleanup occurs.In determining the method,design,and capacity for secondary containment,you need only to address the typical failure mode,and the most likely quantity of oil that would be discharged.Secondary containment may be either active or 612 passive in design.At a minimum,you must use one of the following prevention systems or its equivalent:(1)For onshore facilities:(i) Open Dikes,berms,or retaining walls sufficiently impervious to contain oil;(ii)Curbing or drip pans;(iii)Sumps and collection systems;(iv) Culverting,gutters,or other drainage systems;(v)Weirs,booms,or other barriers;(vi)Spill diversion ponds;(vii)Retention ponds;or (viii)Sorbent materials.(2)For offshore facilities:(i)Curbing or drip pans;or(ii)Sumps and collection systems.The SPCC plan should address appropriate containment and/or diversionary structures or equipment to prevent a discharge,except for qualified oil-filled operational equipment when other requirements are met,and except for flowlines and intra-facility gathering lines at an oil production facility.This is a Class II violation.
