<br />. <br /> <br />It <br /> <br />PROCESS DESCRIPTION: <br /> <br />Two Texas Operations Class I landfills were completed in 1980 - the <br />Oyster Creek 80-4 landfill and the Plant B B-51 landfill. The 80-4 <br />landfill had a capacity of 6,420 cubic yards and is now full. Negotia- <br />tions with TWC for closure are in progress. The B-51 landfill had a <br />capacity of 23,300 cubic years and will be full by January, 1987, due to <br />routine deposits plus cleanup of the Farley Street site estimated at <br />2,000-2,500 cubic yards. Cell #2 of the new B-51 landfill will have a <br />capacity of about 30,000 cubic yards and is intended to serve all of <br />Texas Operations (including La Porte) from 1987 through 1990. The three <br />remaining cells will be permitted and constructed as required. The <br />volume of materials to be 1andfi11ed should decrease significantly when <br />the rotary kiln is operational in 1989, but there wii1 always be ash and <br />other incidentals to landfill. <br /> <br />The B-51 landfill will be double-lined using 80 mil HDPE flexible <br />membranes. It will be constructed in accordance with current EPA and <br />TWC guidelines and will incorporate the latest available technology in <br />landfill construction. <br /> <br />EQUIPMENT LIST: <br /> <br />Earthwork <br /> <br />HDPE Liner Systems <br /> <br />Leachate Collection <br /> <br />III.
