Clean compound of any debris, place into station dumpster. 0 Obtain operational readings of the following: time/date and gallons registered on totaling meter, time/date and kilowatts registered on electric meter, time/date and LEL %, time/date and pressure readings from all water carbons. Influent and effluent samples are collected pursuant to permit requirements. Samples are collected between the second water carbon and the aeration tank and analyzed for TPHg, MtBE, TBA, and BTEX on a weekly schedule. Samples are collected between the third and fourth water carbon an analyzed for TBA on a weekly schedule Carbon Change-Out 1. Shut treatment system off 2. Disconnect carbon unit(s) that is to be changed out 3. Remove all liquid from carbon with pump and place water into 55-gallon drum for later disposal through the carbon system. 4. Place plugs on inlet and outlet of carbon unit(s) to be removed 5. Using drum dolly, place carbon units outside of treatment compound near compound fence and label as non-hazardous waste for removal by U.S. FilterWestates Carbon. 6. Reposition remaining carbons into new positions, with drum dolly, for restart. 7. The following will be performed prior to restart. • At delivery, inspect all water carbons for the following. Lid stamped with CC-602 and that carbon is completely flooded with water. If either of these conditions is not met, do not take delivery of said carbon vessel(s). o Samples of the water inside each delivered carbon will be obtained and analyzed using EPA method 602 for TPHg, benzene, toluene, ethylbenzene, xylenes and Methyl tert-Butyl Ether (MTBE). o The new delivered carbon(s) will not be installed into the water treatment system, until results from the above mentioned testing confirms that the carbon units are clean. o Within 72 hours of restarting the system, a sample will be obtained from the effluent and analyzed for pH (EPA 150.1), TPH (EPA 418,1), BTEX, 5 Oxygenates including MTBE and TBA (EPA 8260), Total metals Cd, Cr, Cu, Pb, Ni and Zn (EPA 200) and Total Toxic Organics (EPA 624 & 625). If any discharge limits is exceed the system will be turned off, and a carbon change-out will occur. o Carbon change-out will proceed as has been previously indicated for this site. The #1 carbon is removed, the 42 carbon is placed into the #1 position, the #3 carbon is placed into the 42 position, the #4 carbon is placed into the #3 position, the 45 carbon is placed into the 44 position and the inspected and tested newly delivered carbon is placed into the #5 position. 6. Restart system, check for leaks in the system, repair as necessary. 4 WATER TREATMENT modification May 2005
