Sampling
Highlights

FTS successfully negotiated a reduction in the groundwater monitoring program with the MPCA both in terms of frequency and laboratory analyzed parameters. The reporting requirements were reduced as well. The financial impact of the program reductions was an approximate $35,000 annual cost decrease which will be recognized until the termination of the monitoring program.

Regulatory Agency

Minnesota Pollution Control Agency (MPCA) and US EPA Region V/CERCLA

COC

VOCs, SVOCs, PAHs, metals, and cyanide compounds 

Project Description

The site covers approximately 38 acres and is located in the city of St. Paul, in Ramsey County, Minnesota.  Historically, the site was used to produce foundry coke and coking by-products such as coal tars and coal tar distillates.  The coking facility operated at the site from 1917 to 1979.  In 1978, the facility owner and the Minnesota Pollution Control Agency (MPCA) entered into an agreement that established conditions for the facility's demolition and an investigation of the subsurface.  The company demolished all standing structures and removed storage tanks in 1981. The site was acquired in 1981 by the Port Authority for the St. Paul Energy Park.  Office buildings and light industrial buildings now occupy the site.

Current Activities Performed
