Colorado Smelter Site Makes Superfund List

Decommissioned site used by CF&I, now property of EVRAZ Pueblo

           Long gone are the glory days of industry, when the Colorado Fuel and Iron Company was the number one employer in Pueblo. Built in 1881, CF&I produced railroad supplies and fuel for the Denver and Rio Grande Railway Company. The steel mill continued to drive industry in Pueblo until its decline in the early 1980s. Following years of bankruptcy claims, it was purchased in 2007 by the Evraz Group. In addition to the steel mill, Pueblo was home to five ore smelters, including the Colorado Smelter which was recently named a Superfund site by the EnvironmentalProtection Agency (EPA).

Neighborhood effected by slag contaminants
Over many years the waste slag produced during the process or ore refining was dumped into a ravine located between Santa Fe Ave. and I-25. The waste contains hazardous materials which threaten public health. Although early investigations in the 1990s revealed cause for concern, official tests were not conducted until 2010. Ground samples from the slag pile and the neighboring residential area were found to contain elevated levels of lead and arsenic. Both contaminants are linked to health problems -including neurological damage and cancer- and pose a higher threat to children.

        In 2014, the Pueblo City-County Health Department applied for and received nearly $200,000 in grant funds for community outreach and education. As of December 11, 2014, the Colorado Smelter was added to the National Priorities List (NPL) of Superfund sites. Rising 30-feet high along the right side of Santa Fe Ave, the slag pile covers an area of approximately 700,000-square-feet. Superfund will oversee the cleanup process, which is expected to take several years to complete. For those interested in learning more about the Colorado Smelter site, a community advisory group meeting is scheduled for June 9th from 5:30 pm – 7:30 pm at the Steelworks Museum of Industry & Culture.
