From The Canon City Daily Record (Sarah Rose):

The Cotter Corp. reported a water spill at their site [November 26, 2015] to the Colorado Department of Public Health and Environment, the CDPHE said.

“(Cotter) discovered a spill of approximately 1,800 gallons of water at the pumpback line immediately upstream of the SCS dam on Cotter property,” a CDPHE email states. “They believe that the spill occurred overnight or early that morning. All water was drained back to the sump and no standing water was left on the ground. The leak has been repaired and the pumps have been turned back on.”

The CDPHE stated this incident is currently under investigation, but they believe water did not go beyond the property.

“A multi-part containment system keeps surface water and groundwater on Cotter property from entering Lincoln Park,” the email stated. “System features include a compacted clay barrier extending to non-porous shale on the upstream side of the Soil Conservation Service Dam, a water collection pipe and three pumps. An underground cutoff wall downstream adds another layer of protection.”

Meanwhile there was another spill yesterday, December 3, 2015. Here’s a report from Sarah Rose writing for The Canon City Daily Record. Here’s an excerpt:

Thursday morning Cotter employees discovered that the pumping system shut down, CDPHE said.

“Cotter personnel then inspected the SCS pumpback line and found the location of the break,” a CDPHE email stated. “Based on the amount of time between the morning inspection and observing the 10 a.m. shutdown, Cotter estimates that approximately 500 gallons of water leaked from the pipe line. Leaked water flowed approximately 20 feet, ponded in a slight depression and infiltrated into the soil. It appears that the water stayed on Cotter property.”
