Twin Cities Army Ammunition Plant (TCAAP), Arden Hills, MN

Ramsey County · 2013 – Present

About

TCAAP is the largest contiguous Brownfield property in the Twin Cities metro area. Bay West and our key staff have played an integral role at TCAAP over that past 20 years as the investigation and remediation contractor on several of the most high-profile waste disposal sites on the property, the redevelopment consultant for a development firm, and the third-party consultant for Ramsey County, providing technical expertise and oversight of cleanup activities.

Services

INVESTIGATION AND REMEDIATION CONTRACTOR

Bay West has performed investigation and remediation work at eight sites at TCAAP. Some of our more significant remediation efforts are summarized below:

  • Excavation of 40,000 yd3 of soil containing shell casings, metals contamination, and asbestos waste with stabilization and off-site disposal of 20,000 yd3 of lead-contaminated soil.
  • Construction/start-up of a pilot-scale soil vapor extraction/air sparge remediation system.
  • Investigation & remediation of a 10-acre burn pit and remediation of lead-contaminated groundwater.
  • Remediation of former wastewater disposal pits contaminated with metals, nitroglycerine, and asbestos.

RE-DEVELOPMENT CONSULTANT

Bay West key staff conducted third-party oversight of the Phase I/II conducted by the federal government on 585 acres of TCAAP. Our staff became intimately familiar with TCAAP’s operational history and investigation and remediation activities. As the technical and field lead for a major Twin Cities development firm, Bay West staff prepared and obtained approval of a field sampling plan and QAPP to assess the property. Our staff conducted the assessment work and were responsible for scheduling, coordination, and staffing of drilling and environmental field staff. The field scope included completion of more than 300 soil borings and collection of over 1,000 soil, groundwater, and soil gas samples for laboratory analysis.

THIRD-PARTY CONSULTANT

Bay West is providing third-party oversight during demolition, investigation, and remediation activities on 427 acres of TCAAP purchased by Ramsey County. Bay West’s extensive history at TCAAP conducting investigation and remediation work gives us a unique perspective as we consult, review, and comment on every technical deliverable prepared by the County’s remediation contractor.

Bay West provides full-time field oversight with our veteran staff. Our primary field supervisor worked on several remediation projects at TCAAP as a Bay West field technician and brought this first-hand knowledge of TCAAP to the project.

Bay West has conducted independent soil sampling on the project on behalf of the County to supplement the existing dataset and lend additional confidence that significant environmental concerns have been identified and will be remediated under the County’s fixed-price remediation contract.

At the conclusion of demolition and remediation activities, Bay West will review the response action implementation reports and assist the County in obtaining a Commissioner’s Certificate of Completion and a change in land use from industrial to unrestricted residential.
