Environmental Due Diligence and Massachusetts Contingency Planning
Regulatory Compliance Services/brownfields
1. Brownfields in Providence, Rhode Island
|
A brownfields investor recently retained M&A to provide environmental site assessment
and related construction support services during the building of a 24,000 square foot medical
research, health care, and office complex, on an inner-city site abutting an abandoned
gasoline service station that had been delinquent for many years. M&A completed the ASTM
Phase I/II project in four weeks. Phase II risk assessment findings concluded that historic
site contamination presented no significant risk based on the intended future site use.
Existing urban fill delineated during Phase II ultimately dictated a foundation design change
to make the site work. |
2. Environmental Assessment at Site for Retail Construction
|
M&A directed fast-tracked ASTM-compliant PHASE II environmental assessment activities,
site redevelopment cost estimation, and successor LSP services that facilitated construction
of a new retail facility at a former automotive repair location. M&A prepared a Release
Abatement Measure (RAM) Plan to address multiple contaminants present in the soil. At project
completion, approximately 800 tons of petroleum contaminated soil were recycled, 3,100 tons
of coal/coal ash were sent off-site for beneficial reuse, 5 tons of railroad timbers were
landfilled, and 50 tons of ACM mixed with soil were landfilled under a DEP emergency
certification. MCP response actions achieved a permanent solution without instituting a
Notice of Activity and Use Limitation (in essence, a deed restriction) at the site. |
3. RCRA Facility Investigation and Interim Measures Program
|
M&A undertook this investigation at a major manufacturing facility of 20 acres that
had been the site of metal manufacturing operations for over 100 years in Westfield,
Massachusetts, under a Consent Order administered by USEPA Region I. Site characterization
efforts were focused at 45 Areas of Concern on the property. Investigated were areas of
shallow, intermediate, and bedrock groundwater, surface and subsurface soil, sediment and
surface water, and soil gas. To accelerate cleanup, an interim remedial measures (IRM)
program was developed in coordination with the USEOA. IRM activities decommissioned an above
ground storage tank farm and two underground gasoline storage tanks. Petroleum impacted
soil was segregated based on field screening tests that allowed less contaminated soil to
be recycled as landfill cover while the more impacted soil was thermally treated. On-site
treatment of soil at the sludge lagoons, showing TLCP metals, was cost-effective management
of the waste. |
