zinc concentrations are relatively high, but generally consistent with the Lake Emma sediments in the Sunnyside Basin (Table D-2 , page D: 4 112 Application for the Sunnyside Mine and Mill) . pH, conductivity, acid-base potential , and texture are all within reasonable bounds for plant growth media. Given these characteristics , it would be reasonable to attempt revegetating these materials . It should be noted that attempts were made for two weeks to pump these pond sediments into tanker trucks for transport to Tailings Pond no. 3 in strict compliance with the permit. However, the sediments could not be slurried by air or high pressure water, owing to the silt loam texture of the material . In order to clean the ponds , a 1 1/4 yard track mounted excavator and open dump truck were finally utilized. No method existed to load the sediment into closed tanker trucks . Hauling this saturated sediment by open truck down the Eureka Creek road was not possible, and on site deposition in excavated pits was employed. Textural analyses show that these sediments are not precipitates (sludges) referenced in the permit for disposal at TP no. 3 . Rather, analytical results show that the excavated sediments have a good likelihood of successful revegetation, and it is the intention of Sunnyside Gold Corp. to attempt a vegetation test plot on these materials during the 1988 growing season. Question: 4. The American Tunnel area was observed. Pond sediment slurrying and transport to TP #3 was occurring. Equipment storage and salvage was observed. Upland diversion drainage was discussed. Minimization of erosion requires some consideration when channelizing flows. Response: A berm, roughly 100 feet long, will be constructed along the state highway to divert runoff from the American Tunnel settling pond no. 1. Question: 5 . The possibility of terminating refuse pile leachate sampling was discussed, as the flow is minimal (hard to sample) and likely untreatable (diversion to sed.
