What are the <br /> plans for closing this line? •.If testing indicates the line <br /> has leaked, how will clean up be accomplished? <br /> V-A-Step 2-4 <br /> o Describe procedures and equipment to be employed to protect <br /> personnel during closure activities (e.g. vapor monitoring, <br /> personal protective equipment) . <br /> V-A-Step 2-5 <br /> o What parameters will the water from the third rinse be <br /> analyzed for? <br /> o What are background levels? <br /> V-A-Step 3-1 <br /> o How far from the tank are the proposed borings? <br /> o Be more specific about depth of soil borings and depths <br /> where samples will be collected. <br /> o How will samples be collected from beneath the tank? <br /> Describe the procedure you will use to gather undisturbed <br /> samples from beneath the tank. <br /> o Four shallow soil borings are inadequate to characterize <br /> potential tank overflow and/or leakage. Please describe the <br /> rationale for selecting sample locations and depths, the <br /> number of samples to be collected and the parameters to be <br /> analyzed for. <br /> V-A-Step 3-3 <br /> o I£ phenols or chlorinated phenols are found through <br /> qualitative analysis (EPA 8020) then confirm with GC/MS or <br /> GC/MSD. <br /> o Test for fluorides. <br /> V-A-Step 4 <br /> 0 Is tank being removed or filled in?
