Redevelopment at the Site

The residential soils (OU1) segment of the site remains in residential use. There are about 4,500 residential properties and 10 schools in the site area. Local residents and visitors continue to use seven parks within the site boundaries for recreation. The former Omaha & Grant Smelter location (OU2) is today the location of the Union Pacific Railroad Company, Pepsi Bottling Company, Denver Coliseum, various other commercial and industrial businesses, as well as the Globeville Landing Park. At OU2, the city of Denver, with EPA oversight, is conducting cleanup activities to remove waste material from underneath the Denver Coliseum parking lot and create an open drainage basin to help with stormwater management. Globeville Landing Park will also be redesigned and enhanced by this effort. The former Argo Smelter location (OU3) remains an industrial and commercial area nearly entirely paved and heavily impacted by Interstate 70, Interstate 25 and connecting roadways.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.

In June 2014, EPA placed Notices of Environmental Conditions in the property files of approximately 60 residential properties in OU1 where, despite all efforts, EPA was not able to gain access from the property owners. The notices are filed at the City and County of Denver Clerk and Recorder’s office. Residents and owners of these properties will also receive annual mailings alerting them to the potential or known contamination issue and providing them with simple steps to avoid exposure.
