Denver and Waste Management to pay $265,000; cited for violations of cleanup order
Release Date: 7/16/2004
- Denver -- The City and County of Denver, Waste Management of Colorado, Inc. and Chemical Waste Management, Inc. will pay a penalty of $265,000 after being cited for their failure, on numerous occasions from August through December 1998, to comply with an EPA order directing cleanup of the Lowry Landfill Superfund site.
In the complaint filed with the consent decree, Denver, WMC and CWM were also cited for their failure to immediately notify EPA and the Colorado Department of Public Health and Environment that cleanup standards were exceeded, to submit data demonstrating the exceedances to the agencies on time, and to immediately take action to address the problem. These violations did not increase the risks to human health or the environment posed by the site.
The Superfund site, located in unincorporated Arapahoe County, is approximately 15 miles southeast of downtown Denver. Denver is the current owner and a past operator; WMC is the current operator; and CWM transported wastes to the site.
In November 1999, Denver, WMC and CWM began operation of a soil-vapor extraction system to remove contaminated gas from the subsurface environment at the site. EPA and CDPHE continue to monitor gas levels at the site to ensure they meet landfill gas cleanup standards updated by EPA in September 2001.
Monitoring since the time of the operation of the soil-vapor extraction system has indicated that landfill cleanup standards are being met.
