TO: Distribution Interoffice Communication FROM: DATE: SUBJECT: S. V. Corkran March 28, 1990 TC Transfer ASU Acclimation Transfer of TC material to the VCM ASU will increase organic loading on the ASU by approximately 350%. This number is based on single-point COD and TOD data. Attached are hydraulic and organic stream data used to base this loading estimate, and an acclimation schedule. In general, methanol will be used to increase organic loading on the ASU until the LCCP TC Transfer system is installed. The methanol is easily flow controlled by VCM personnel. When the TC transfer system is operational, the organic loading will be replaced, in two steps, with an appropriate loading of TC water. The required rate will be determined by TOD analysis at LCVCM and will be controlled by LCCP personnel. LCCP must be able to route the set amount to VCM and divert the remainder to the LCCP Secondary for " 2 days to allow a smooth transition. Discussions with Jim Shamburger (LCCP) on 3/28 indicated that installation of a floating roof on the fuel oil tank, if agreed upon, would probably result in a startup date of 4/16. This is consistent with the attached schedule. The loading increase schedule is significantly more aggressive than in the past; however, the rate will be increased ahead of schedule if the condition of the system is favorable. By 4/18, all of the Phase I TC wastewater should be directed into the VCM ASU. Please review the attached material and return any comments to me ASAP. S. V.

The lab will run a TOD analysis and will inform the VCM Shift Supervisor (S/S) of the result. The S/S will determine the desired flowrate and inform the Steam Plant Control Room at LCCP (494-5310) of the setpoint. Steam Plant personnel will be responsible for making the appropriate adjustment in flow. This flow control operation will last " 2 days (4/16-4/18) until the remainder of the Methanol is backed out and all of the TC wastewater is directed to the West Basin. Once the entire stream is being transferred, a TOD analysis will be conducted each week day and the result included on the VCM Secondary Log. LCCP will record flow data.

Bsll March 4, 1990 subject: Bioremediation Core and Interval Sample Results From LCCC Analyses VIO Three individually consolidated core samples and three individually distinct foot interval core samples were taken from each of the following facilities: North Lagoon, South Lagoon, North Stormwater Diversion Pond and South Stormwater Diversion Pond. The core sample locations were adapted from the screening and sampling procedure developed by PED. The consolidated core samples were analyzed for volatiles at LCVCM using the Toxicity Characteristics Leaching Procedure (TCLP). The components the samples were analyzed for are tabulated in Table 1. The TCLP leacheate concentrations from these samples have been tabulated in Table 2, for those compounds with concentrations above the minimum detectable limit. The TSS, VSS and percent solids were also determined for most of these samples. These data have been tabulated in Table 3. American Laboratories and Research Services (ALRS) performed a complete hazardous waste characterization on the consolidated core samples. These tests include corrosivity, ignitability, reactivity, and a complete TCLP for metals, pesticides, herbicides, volatile organics, acid fraction and base neutral fraction. All of the core samples were not corrosive, not ignitable, and not reactive to cyanide, sulfide or water. The silver and selenium levels were less than 0.005 mg/1. The TCLP leacheate volatile concentrations, above detectable limits, have been tabulated in Table 4. More results on metals and TCLP leacheate concentrations are forthcoming. The foot interval samples were analyzed by ALRS, using head space analysis for benzene, toluene, ethylbenzene, xylenes, trichioromethane, EDC and percent moisture. These results have been tabulated in Table 5. The volatile data is approximately 20 times greater than the equivalent TCLP leacheate concentrations. T. R.
