American Sode verbally reported a release Lo the 24-hour Environmental Emergency Spill
Reporting Line on Friday, September 29, 2000. 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 Creek. Enclosed are copies of laboratory analysis reports for
these two water samples.
The sample identified 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 1!a mile downstream from the release in the vicinity of an established in•igation
diversion, Please note that the laboratory analysis report for each sample inadvertently shows
the time of sample cellection as A.M. instead of P. M.
Data obtained from the USGS stream flaw 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 ere assumed to have been transient and
dispersion and dilution by water in the creek should have mitigated any possible locali2ed 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.
Delivering a Crystal Clear Advantage.
