DRAFT Ver. 1-C-doc-4-5-10 10. Containment or Diversionary Structures or Equipment to Prevent Oil Discharge (§112.7(c)): Table G-10 Containment and/or Diversionary Structures or Equipment Appropriate secondary containment and/or diversionary structures or equipment'is provided for all oil handling containers, equipment, and transfer areas to prevent a discharge to navigable waters or adjoining shorelinesb. The entire secondary containment system, including walls and floor, is capable of II containing oil and is constructed so that any discharge from a primary containment system, such as a tank or pipe, will not escape the containments stem before cleanup occurs. 112.7 c 'Use one of the following methods of secondary containment or its equivalent: (1) Dikes, berms,or retaining walls sufficiently impervious to contain oil; (2)Curbing; (3)Culverting, gutters, or other drainage systems; (4)Weirs, booms, or other barriers; (5)Spill diversion ponds; (6) Retention ponds; or(7)Sorbent materials. Except as noted below in footnote b for bulk storage containers and tanks(and loading/unloading racks), containment may be active or passive in design or operation, and the containment method, design, and capacity need only address the typical failure mode, and the most likely quantity of oil that would be discharged. b Secondary containment for bulk storage containers and tanks must meet additional criteria (40 CFR 112.8(c)for stationary bulk tanks/containers and 40 CFR 112.8(c)(11)for portable tanks/containers(see Section A of this Plan). Secondary containment for tank truck/rail car loading or unloading racks must meet the criteria in 40 CFR 112.7(h)(1) (see Table G-15 of this Plan). 11. Containment Impracticability (§112.7(d)): Table G-11 Determination of Impracticability and Provision of Alternative Measures N/A This facility has determined that the installation of containment structures or pieces of equipment required by/listed in §§112.7(c) and 112.7(h)(1), and §§112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 112.10(c), 112.12(c)(2), and 112.12(c)(11)to prevent a discharge as described in §112.1(b)' is not practicable. For bulk storage containers, the facility will conduct both periodic integrity testing of the containers and periodic integrity and leak testing of the valves and piping; and, unless a Facility ❑ II Response Plan has been submitted to US EPA under§112.20, attached to this plan is an oil spill contingency plan following the provisions of 40 CFR part 109, and a written commitment of manpower, equipment, and materials required to expeditiously control and remove any quantity of oil discharged that maybe harmful. [§112.7(d)] The determination that secondary containment is impracticable and provisions in lieu of secondary containment have been reviewed and certified in writing by a Professional Engineer. The PE review and ❑ II certification must be included with this Plan. (§§112.6(b)(3)(ii) and 112.7(d)] The following is a clear explanation of why such containment structures or measures are not practicable: x a A"discharge as described in§112.1(b)" generally means a discharge of oil in harmful quantities to a navigable water of the Unites States. A harmful quantity is the amount of oil which could cause a sheen upon the water, create an emulsion, or deposit a sludge upon the shoreline. `Navigable waters of the United States"may include storm drain systems and culverts.
