SPCC PLAN <br />• + Contents of the SPCC Plan <br />6.2 Spill Containment <br />The following discharge prevention measures will be implemented during site operations: <br />Should storage containers or tanks (with a combined aggregate aboveground storage <br />capacity exceeding 1,320 gallons) be required for temporary storage of liquids potentially <br />containing hydrocarbons, the containers or tanks will be designed and constructed for <br />hydrocarbon storage. The containers and tanks will be welded steel or polyethylene and <br />placed within bermed containment areas constructed as described below. <br />Bermed containment areas: <br />• Constructed of native soil with intrinsic characteristics and mechanical <br />compaction sufficiently impervious to prevent discharge <br />• A capacity to contain the volume of the largest tank within the area (110 percent <br />allowance for precipitation accumulation) <br />o Liquids that accumulate inside any containment areas will be visually inspected <br />for oil or produced water <br />o If no oil or produced water is detected, accumulation of rainwater will be allowed <br />to evaporate or pumped out if necessary <br />+ Drip pots/pans will be used to contain drips/releases during refueling or loading <br />operations <br />+ Operators will visually inspect area during normal work activities for presence of oil or <br />other petroleum products , large-rooted plants or burrowing animal holes that may impact <br />integrity of the containment system, or leakage/rupture of aboveground tanks, valves, and <br />flow lines. <br />Any containment areas will be inspected after abnormally heavy rainfall events. Excess <br />precipitation will be allowed to seep into the earth and evaporate. Levels will be <br />monitored and excess water removed to prevent overflow. <br />6.3 Spill Prevention Protocols <br />Designated areas of the drilling pads will be equipped with appropriate containment for storage of <br />small quantities of fuels, hydraulic fluid, and lubricants needed for operation and maintenance of <br />equipment, such as generators, pumps, and compressors. These containment areas will be <br />equipped with secondary containment berms, drip berms and spill pads, as appropriate. Spill kits <br />will be provided in easily accessible areas at each drilling pad. <br />All equipment will be inspected for leaks when it arrives on site. The soil beneath the drilling <br />rigs and other equipment will be protected by installing secondary containment berms, drive- <br />through berms, fiiel disconnect and drip berms, and spill pads as appropriate. <br />American Shale Oil, LLC 11
