Environmental Assessment Morksheet Information Based on the estimates in the Phase I study the small CRF (26 shops, 60 canisters/day) should sewer about 64,000 gallons per day and the large CRF (45 shops, 90 canisters per day) should sewer 96,000 gallons per day. There was a market survey at the end of Phase I. the shops expressing interest in canister service in that survey would h require oua�eialstbehandledby th seventy o canisters per eCRFa .tias also possible to estimate the amunts of sludges for the shos inptheseniludinterest werenconsisientservices the sludgegallonageThe amounts of metals 9 estimated in Phase I. The amounts of the batch dumps (about forty percent of the total gallonage according to the Phase I estimate) and the amounts of the metal and cyanide contained in them were not verified in the market survey. About thirty shops had announced their intention to use the CRF by the May 1 deadline, but toe have not yet seen the data on which waste streams will be t pro- vided. The estimates in this letter are based on the earlier Informatioy.hat Is the late Phase I survey. I will discuss metals, cyanide, pH, dissolved solids, and sludges separately. The sewered flow from the CRF should average about ?59000 gallons per day for the thirty shop case. At this flow the discharge of metals and cyanide to the sewers would be: WCOC Limit, lb/day 1b/yr !9/1 Discharged Dischar ed cadmium 2 (1) 1.2 (0.6) 310 (160) Chromium 8 (5) 5.0 (3.1) 14250 (780) Copper 6 3.7 940 Lead 1 0.6 160 Nickel 6 3.7 940 Zinc D 5.0 16250 Cyanide d 2.5 620 The quoted limits are those for an industrial discharger and were given to me byDon Hadoeo r f the KWCC in a phone conversation the morning of 1083 February
