Matrix provided environmental services to support and advise the Pueblo Chemical Depot Reuse Authority regarding the 15,800-acre PuebloPlex site, specifically on issues related to environmental liabilities and RCRA permitting associated with lands intended for transfer from the U.S. Army. The services included technical consulting on environmental issues with the potential to affect the property transfer and redevelopment initiatives associated with an economic development conveyance application and negotiations between stakeholders, including PuebloPlex, the U.S. Army, Army Corps of Engineers, Environmental Protection Agency, and Colorado Department of Public Health and Environment.

PuebloPlex comprises facilities historically used for munitions storage and currently occupied by the U.S. Army. It is adjacent to the Pueblo Chemical Agent Destruction Pilot Plant, designed to destroy munitions formerly stored at the property. Due to its historic use, PuebloPlex has numerous areas of environmental concern constraining redevelopment opportunities.

Matrix provided the following environmental consulting services: participated in stakeholder meetings in support of PuebloPlex redevelopment; worked with stakeholder representatives to provide technical opinions related to environmental cleanup work that could affect the future redevelopment; provided technical reviews and professional advice regarding the establishment of cleanup levels for contaminated property, the extent of cleanup necessary, transfer phasing strategies, and land use controls and/or restrictions with respect to future reuse; analyzed environmental issues and concerns unique to each redevelopment parcel, including monitoring implementation and progress of all remediation and mitigation activity; reviewed environmental documentation related to potential transfer parcels, including potential constraints/parameters for reuse planning; helped coordinate with environmental legal counsel to understand the broad scope of potential environmental liability.
