This initial notification was followed by required written documentation on October 2, 2000 describing important details regarding the release. As referenced in the notification letter, two water quality samples were collected in order to provide water chemistry information on the release water and the water quality downstream from the release in Piceance Greek. Enclosed are copies of laboratory analysis reports for these two water samples. The sample ident'rfied as L29208-01 °Pit @ pilot plant rd° was collected at 5:20 P.M. from the temporary containment sump constructed to divert the flow of release water away from the creek on the day of the release. The second sample, L29208-02 "Irrigation Diversion" was collected the following day at 2:30 P.M. from Piceance Creek. The sample was collected approximately t/z mile downstream from the release in the vicinity of an established irrigation diversion. Please note that the laboratory analysis report for each sample inadvertently shows the time of sample collection as A.M. instead of P. M. Deta obtained from the USGS stream flow monitoring station (Piceance Creek blow Ryan Gulch, near Rio Blanco, Colo., Station Number 09306200), just upstream of the release location indicated a daily average flow of 5.3 cubic feet per second in Piceance creek on the day of the release. _ The calculated volume of the release was approximately 6,000 gallons. Given the volume of flow in Piceance Creek, the effects of the release are assumed to have been transient and dispersion and dilution by water in the creek should have mitigated any possible localized impact from this release. In addition to the operational changes implemented to prevent this type of release, mitigation measures also included the excavation of the soil material contacted by the release water.
