3.2Containment and Diversionary Structures [112.7(c) and 112.7(a)(3)(iii)]

The facility is configured to minimize the likelihood of a discharge reaching navigable waters.

The following measures are provided:

Secondary containment for the oil storage tanks, saltwater tank (which may have small amounts of oil), and gun barrel is provided by a 60 ft x 40 ft x 2.5 ft earthen berm that provides a total containment volume of 867 barrels (36,423 gallons), as described in Section 3.2.2 below. The berm is constructed of native soils and heavy clay that have been compacted, then covered with gravel. A clay layer in the shallow subsurface exists naturally and will stop any spilled oil from seeping to deeper groundwater.

The tank truck loading area is flat but gently slopes to the southeast, where a crescent-shaped, open berm has been placed to catch any potential spills from tanker transport trucks. The bermed area provides a catchment basin of 40 barrels (1,680 gallons), the maximum expected amount of a spill from the tanker due to overtopping of the truck during loading. In addition, the end of the load line is equipped with a load line drip bucket designed to prevent small discharges that may occur when disconnecting the hose.

Booms, sorbents, shovels, and other discharge response materials are stored in a shed located in close proximity to the loading area. This material is sufficient to contain small discharges (up to approximately 200 gallons).

These measures are described in more details in the following sections.
