October 20, 1982 <br /> Project 116-1.3 <br /> - 2 - <br /> Additional industrial wastes consisting of wet-solid sludges were <br /> accepted for disposal in the Group 1 Trench Landfill Area and were <br /> placed in Trench #3. Liquid wastes consisting of drilling mud and <br /> gas-well brines were disposed in the Evaporation Pond system. Table 2 <br /> below, provides volume data on all Group 1 waste approved for disposal _ .. <br /> in Landfill Trench #3 and liquid waste discharged to the Evaporation <br /> Ponds. <br /> TABLE 2 - GROUP l WASTE AND LIQUID WASTE <br /> FTIC Drilling Mud Brine <br /> Month (cu.yd. ) (bbls. ) (bbls. ) <br /> July 1982 880 1,750 / 0 <br /> August 1982 100 0 1,120 <br /> September 1982 1,420 5,610 965 <br /> TOTALS 2,400 7,360' 2,085 <br /> Note: 1 bbl. = 42 gallons <br /> Group 1 sludge wastes placed in Disposal Trench #3 are covered, when <br /> possible, on a daily basis with a minimum 6 inch thickness of clean <br /> earth as requested by representatives of the California Department of <br /> Health Services. <br /> Landfill trenches in the Group 1 Disposal Area are checked each quarter <br /> for the presence of water in the leachate collection sumps. During this <br /> monitoring period, all- trench sumps have remained dry. <br /> During this monitoring period, Ponds #l, #2 and #3 were cleaned and <br /> accumulated solids were placed over Group 2 solid waste.trench #2 as <br /> explained in our letter of August 2, 1982. Mr. H. Eagle, State Water <br /> Resources Control Board, requested that these drilling muds not be <br /> moved into Group 1 Trench #3 as they may plug the leachate collection <br /> system. Ponds #1 and #2 were drilled and sampled by Dwight Baier. The <br /> drill holes were plugged by Kleinfelder & Associates in accordance with <br /> specifications suggested by H. Eagle. .. When the soil test details and <br /> hole plugging data is received, it will be forwarded to your office. <br /> Groundwater samples were collected from Monitoring Wells #7' and #9 on <br /> October 4, 1982. Priortosampling, each well was bailed to remove a <br /> volume of water equal to five well volumes. ,The sample was then <br /> collected and filtered` through a' #42Whatman`Filter Paper to remove <br /> suspended solids. The sample was then split and half of each sample <br /> was fixed with nitric acid to ,preserve for metal ions. <br /> These sampling methods and subsequent analyses are in Conformance with <br /> "Standard Methods for the Fxamination of Water and Wastewater". <br /> Analyses were performed by Nelson Laboratories of Stockton, California, <br /> `Betac_Associates <br />
