Here's some need-to-know information for the week:

Land use restrictions formalized at Marshall Landfill Superfund Site

The City of Boulder has partial responsibility for long-term maintenance and monitoring at the Marshall Landfill Superfund Site, located south of Marshall Road along S. 66th Street on privately owned land in Boulder County. The city and Republic Services used the landfill from 1965 to 1992, and the U.S. Environmental Protection Agency (EPA) designated it as a Superfund site in 1983. “Superfund” refers to the Comprehensive Environmental Response, Compensation and Liability Act, which requires polluters to pay for and remediate environmental contamination.

Under a consent decree with the EPA, the city and Republic Services share costs at 30% and 70%, respectively, for any clean-up and ongoing activities at the site, such as annual inspections, cap maintenance and annual groundwater and surface water monitoring. The city and Republic Services have completed the required groundwater remediation and will continue to conduct water monitoring to ensure long-term protection at the site.

The city has worked collaboratively with Republic Services, the private landowner, the EPA and the State of Colorado to enter into Restrictive Notices (RN) for the site to provide additional protection. These include prohibiting any development, buildings or digging that would disturb the cap or that would lead to potential exposure to contaminants from waste left in place. Limited uses of the land may be allowed with approval from the EPA and the state.

The RN is currently being routed for signature by the City of Boulder city manager, the landowner, the EPA and the state. More information on the site can be found on the EPA’s website.
