Soil Disturbing Activities & Site Remediation
The contents of this page were initially written to address site remediation activities at the Denver Federal Center (DFC) to comply with two legally binding Consent Orders issued by the State of Colorado Health Department and associated environmental regulations. The resources and procedures associated with soil disturbing activities apply to the states in Region 8.
This page offers links and procedures for:
- Soil disturbing activities: trenching and excavations, earth moving activities, fugitive dust
- Site remediation: Personal protective equipment, respirator requirements, confined space entry, asbestos in soils
Prior to 1946 the DFC was the Denver Ordinance Plant, a 200-building munitions plant where 22,000 employees produced over 7 million cartridges a day for the war effort. The former ordinance plant’s activities resulted in hazardous substances being released to the soil and groundwater. Prior to 1941, the site was a quiet cattle ranch outside of Denver.
After the war, the facility was converted into a smaller federal facility, consisting of federal office and indoor and outdoor laboratory space for 28 federal agencies employing over 6,000 within approximately a square mile campus.
The cleanup involves: assessing impacts to the soil and groundwater, restoring the site to levels protective of human, health, and the environment.
