<br />NRCS is currently reviewing it's previous recommendations for seed mix. The new recommen nonJ 1 <br />different from above, will be used in future reclamation of the site. C ~ ~~~ ~ f ~ /~/ <br />MRCS also recommended that straw (3000 pounds per acre) should be crimped into the soil after <br />seeding and fertilization. Fertilization should consist of the application of 60 pounds of available <br />nitrogen per acre. • .6s r ~ , , f 'I ® 7 <br />~- <br />4.

The moisture from the sludge, and from rainfall, combines with the <br />CKD to form a hard crust which helps prevent erosion of the CICD from both wind and surface water <br />runoff. <br />r <br />5. CICD Sampling and Analytical Methodologies. <br />Appendix E of the attached Hydrogeologic Assessment contains historic chemical analyses of CKD <br />and Fremont sewage sludge samples. These analyses show the CKD solids to be composed <br />predominantly of oxides of calcium, silica, potassium, aluminum, iron, and sulfate. Composite CICD <br />samples also had potentially significant concentrations of minor elements such as barium, arsenic, <br />chromium, copper, manganese, nickel, lead, antimony, selenium, thallium, and zinc. When mixed <br />with distilled water, the samples yield a leachate having an alkaline pH (between about l2 and 13). <br />C1CD samples are collected by Holnam on a monthly basis from the screw conveyor in the kiln located <br />on the south side of the Arkansas River. The monthly samples are composited and analyzed on a <br />quarterly basis. The most recent analytical results are attached. <br />KS-990102 P~gc 4 K-S &Company <br />August 16, 1999 CopyniEht1999 <br />
