Cyprus wanted to know if it was possible to dispose of <br />the sediment from their oil-water separator in the portal <br />area waste disposal site. <br />2. Water used to wash down garage areas, et3c ` s put through <br />a tank-like separator which allows the waYs~ to separate <br />off the top. This oil is subsequently treated as waste <br />oil. <br />3. The water portion is passed through their water treatment <br />ponds and either evaporates or is eventually released <br />into the river. <br />4. Sediments from the process settle out in the bottom of <br />the tank and need to be disposed of from time to time. <br />5. Currently, these sediments are given the standard RCRA <br />(Resource conservation and Recovery Act) tests and <br />disposed of in the local county landfill as solid waste. <br />To date, none of these samples have been considered <br />hazardous. <br />6. Cyprus estimates two cleanings per year resulting in <br />approximately two cubic yards per cleaning. <br />7. Cyprus can provide us with analysis data for past <br />sediment loads and is willing to provide analysis for <br />future loads. <br />
