N O V- 2 9- 9 3 M O N 1 2 4 7 W A T E R W A S T E t L A N D P 0 4 <br />lorry Oehler • <br />November 28, 1883 <br />Paps 3 <br />1500 cubic yards (material to be placed) for material Type 2 is being exceeded by SRK. They <br />have and are currently conducting gradations at a rate of four per acre. This is approximately <br />one test for each 800 cubic yards fora 2-foot thick cover. <br />Another requirement in the November 2 letter was that both the Type 2 and 3rt~aterials have <br />one lab permeability test conducted per acre of installation. As mentioned abode, WWL has <br />not received a summary of ell the laboratory testing in progress. This information (and the <br />testing) is still in the process of being completed. <br />It appears from the field testing summary that a sufficient quantity of testing has been and <br />is being conducted. Testing includes Proctor compaction, in-place density and moisture <br />content, and gradation tests on soils. Instead of repeating the information contained in SRK's <br />interim laboratory and field summary, I will refer to it only. WWL was informed that a copy <br />would be provided to DMG. If you do not receive a copy, WWL can provide you with one. <br />If you have any questions concerning the information contained in this letter, please contact <br />Clint Strechan or me. <br />Yours sincerely, <br />WATER, WASTE & LAND, INC. <br />Douglas O.
