Sierra Chemical Co. <br />RCRA Contingency Plan <br />No operation that has been shut down in response to the incident will be restarted until authorized by <br />the IC. After resolution of the incident, an analysis may be conducted to review level II and level III <br />incidents for determination of the cause, and the corrective action plan to prevent the recurrence. <br />9. Management and Containment of Released materia! and Waste <br />9.1 Containment <br />Once initial release or spill containment has been completed, the IC and EHSS Manager will ensure that <br />recovered hazardous materials and waste are properly stored and/or disposed of in accordance with all <br />applicable laws and regulations. <br />The perimeter of the spill will be confined to dikes, absorbent tubes, or any other materials or processes <br />deemed suitable by the IC. If the spilled/released material is a result of a rupture or leak in a drum or <br />valve, the material will be contained using the most efficient means possible and may include: <br />• Rotating drum(s) to where puncture is on top <br />• Applying wedge into puncture <br />• Placing drum into Overpack turn <br />• Affixing a patch to the puncture/hole <br />Depending on the amount of product and the rate of flow, there may be occasions that the IC may elect <br />to concentrate on confining clean-up rather than container (i.e. small spills). All free standing liquid will <br />be transferred to a marked, compatible container and the remaining liquid will be absorbed with <br />absorbent material and or swept or shoveled into a labeled suitable container. If a spill occurs with dry <br />materials, all materials will be swept or shoveled into a compatible container. All containers holding the <br />hazardous materials will comply with applicable laws are regulations and will be compatible with the <br />waste or materials stored within. <br />Once the response team has control of the spilled/released material, efforts will focus on neutralization <br />of the product and the best available methods for neutralization. As a result of evaluating all resource <br />data available, the IC should be able to determine what methods should be used. <br />9.2 Decontamination (Decon) <br />Though most decontamination efforts for level I or II spill releases may result in the use of safety <br />showers or bathrooms and removal of effective clothing, larger scale releases may require a full decon. <br />In that event, decon will occur once a spill/release has been contained and neutralized. All decon <br />personnel will wear appropriate PPE and all materials used for decon will be considered contaminated. <br />It should be noted that other chemicals may be involved in an incident besides chlorine, and the ERT <br />personnel must evaluate the compatibility and reactivity of decon solutions, and their effects on <br />personnel and equipment. Generally, the decon personnel at Stations #2 will be wearing protective <br />clothing and equipment that is the same "Level of Protection" or one "Level of Protection" less than the <br />Entry Team. General decon procedures are as follows for a Chlorine or Sulfur Dioxide release: <br />• Station #1: Equipment Drop — personnel enter the decon Area and drop off tools and other <br />equipment on the "dirty" side. <br />• Station #2: Gross water rinse of contaminated residue from protective clothing and equipment <br />Prepared By: Issue date: Replaces: Page: <br />ACT Environmental Si <br />Inc. <br />February 25, <br />2016 <br />NA <br />27 of 44 <br />
