Brownfields Redevelopment The Armory

ATON was retained by Green Street St. Louis to aid in the remediation of and secure a comprehensive No Further Action (NFA) letter from the Missouri Department of Natural Resources (MDNR) Brownfields/Voluntary Cleanup Program (BVCP) for the historic St. Louis Armory building.

Completion Date: November 2019

CHALLENGE

Green Street St. Louis is a local commercial real estate development company that offers a comprehensive suite of services from design/construction to project financing.

The project included the preparation of a Phase I ESA, a Regulated Hazardous Building Materials Inspection, the development of a Remedial Action Plan, oversight during hazardous materials abatement, and final clearance sampling. The primary contaminants of concern identified at the site consisted of asbestos, lead, and PCBs.

SOLUTION / METHODOLOGY

ATON prepared a Comprehensive Remedial Action Plan to address all contamination and hazardous material identified at the subject site. The plan included specifications for asbestos and lead-based paint abatement and encapsulation, decontamination procedures for indoor firing ranges, and procedures for disposal of PCB-containing transformers. In order to monitor air quality during and after abatement procedures, ATON collected daily air samples and final clearance samples. After encapsulation of areas with lead-based paint, lead dust wipe sampling was performed, and results compared to residential standards as required by the BVCP.

OUTCOME

ATON completed and submitted a Remedial Action Completion Report (RACR) in November of 2019 to MDNR. All project guidelines outlined in the Remedial Action Plan were met and an NFA letter was requested for the subject property. Future redevelopment plans for The Armory include over 250,000 square-feet of creative office space, with amenities including a restaurant, a greenway path connection, structured parking, and adjacent mixed-use development. ATON assisted Green Street in securing approximately $2M in brownfield tax credits from the Missouri Department of Economic Development.
