Public Comment Open for Lincoln Park Work Document

Draft work plan released for parts of the Colorado Legacy Land Facility / Lincoln Park Superfund Site

November 21, 2022: The Colorado Department of Public Health and Environment and the U.S. Environmental Protection Agency are currently reviewing a draft Work Plan for the Lincoln Park Superfund Site covering Operable Unit 2 (OU2) groundwater and Operable Unit 3 (OU3). This plan outlines how Colorado Legacy Land will collect data related to Lincoln Park groundwater and other areas with contamination or threat of contamination. The goal is to understand the nature and extent of contamination to inform future cleanup actions for previous milling operations.  

The agencies are welcoming public comment on this document and the associated Quality Assurance Project Plan until January 31. Please visit the state’s Lincoln Park website for more information. The department is dedicated to working with site partners to better understand contamination at this site in order to protect human health and the environment.  

This document follows the recent approval of the Draft Remedial Investigation Report, which analyzed what is currently known about the site. The next Work Plan, which will cover the former mill and surrounding area (OU1), is due to the agencies by late winter 2022-23. The agencies divided the Remedial Investigation into two parts, in order to speed up the study of contamination in areas where there is greatest potential for exposure. After the first Work Plan is reviewed, edited, and approved - likely throughout 2023 - Colorado Legacy Land will start collecting data to inform future site cleanup actions. 

The Work Plan will be discussed during the January 17, 2023 Community Advisory Group meeting. These monthly meetings provide an opportunity for the public to discuss site activities and provide input. Community members have the option to gather for the Zoom meeting in-person or join virtually from home.

EPA added the Lincoln Park Superfund Site, two miles south of Cañon City, to the national list of Superfund sites in 1984. The Cotter uranium processing mill, which operated from 1958 until 1979 and intermittently until 2011, released radioactive materials and metals contamination into the environment. Previous cleanup efforts included connecting Lincoln Park residents to city water, construction of a groundwater barrier to minimize migration of contaminated water, and excavation of contaminated sediments in Sand Creek. Colorado Legacy Land took over ownership of the site in 2018.

Information is also available for public viewing at the Royal Gorge Regional Museum and History Center, 612 Royal Gorge Blvd., Cañon City, CO.
