The Colorado Department of Transportation (CDOT) is the responsible party for a site located at 4340 East Louisiana Avenue in Denver, CO (the Site). The Site previously was occupied by the CDOT Materials Testing Laboratory (MTL). The MTL was identified as a source of subsurface contamination and placed under a Compliance Order on Consent (COC) by the Colorado Department of Public Health and Environment (CDPHE) effective June 26, 1995, and subsequently amended on July 31, 1997. Since the discovery of the contamination, CDOT has conducted a variety of monitoring and remedial programs to comply with the COC and to protect the public and the environment.
CDOT requires a contractor to complete all environmentally and regulatory related tasks at the Site. The contractor must operate within all applicable local, State, and Federal statutes and regulations. Additionally, Site work must comply with the COC and all its associated requirements and stipulations, including but not limited to the Site-specific Sampling and Analysis Plan (SAP) and Quality Assurance and Project Plan (QAPP).
