See POLREP #1 for site description and background information.
Work continues on grading the site for optimum surface water drainage and preparation for installation of the clay cap on top of the aluminum smelting waste piles. Clearing and grubbing of the southern site area (Rimmer Brothers property) was completed, and the drainage channel for that area was improved by deepening it and lining it with rip-rap made from concrete already on-site.
Construction of erosion and drainage controls and dismantling and decontamination of an underground storage tank (UST) has been completed. Recent weather (heavy rain) have saturated the soils and continue to make site conditions difficult for managing heavy equipment.
Grade adjustment of the saltcake pile and construction of the diversion channels have been completed as of March 21, 2011.
Installation of the clay and top-soil cap followed by seeding and establishment of a vegetatvie cover.
