Brownfields Project Examples
Former U.S. Steel Facility
New Haven, CT
Client: Coastline Terminals of
Connecticut, Inc.
Description: Triton conducted
a risk based assessment including investigation, design and remediation
services at the former US Steel Corporation site in New Haven for
Coastline Terminals, Inc. This site was formerly owned by US
Steel operating as a 100-year-old steel fabrication manufacturing
facility. Triton completed Phase I and II work at the 16 acre
site including soil sampling to evaluate site conditions and
groundwater monitoring to delineate the extent of petroleum and metal
contamination with respect to CTDEP RSR criteria. This project
included the developed of alternate Surface Water Protection Criteria
for concentrations of lead and zinc detected in groundwater at the
site. The development of the alternate SWPC proved that site
groundwater metal concentrations would not adversly impact water
quality in the adjacent Quinnipiac River, thus eliminating the need for
groundwater remediation.
A comprehensive remedial action plan was developed
detailing an innovative approach to addressing areas of contamination
which exceeded RSR criteria. An engineering control consisting of
clean fill sub-base materials and asphalt pavement was proposed to
prevent exposure to underlying soils. Triton also received DEP
approval for a regulatory variance for the fill material on site.
This approved variance significantly reduced the quantity of soil
requiring remediation, resulting in significant cost savings.
Role: Environmental site
assessments (Phase I, Phase II, Phase III), remediation planning,
obtained variance from CTDEP for Widespread Polluted Fill, applied for
use of engineered controls as part of remedial strategy, consulting on
property transfer issues.
