Environmental, Asbestos and Geotechnical Services in Support of Brownfield Site Redevelopment

RETAIL FACILITY

Clifton, New Jersey

The CP Environmental Group (CPEG) team was hired to perform environmental, asbestos, and geotechnical services in support of the redevelopment of a 1-acre site consisting of six parcels.  One parcel was the former City Line Service Station (City Line) and the other five parcels were used for residential, commercial and light industrial uses.  The City Line station had been in operation as a gasoline retail facility since approximately 1935.  The site was redeveloped into a retail pharmacy.  

Subsurface investigations identified soil and groundwater impacts including petroleum hydrocarbons (gasoline).  During redevelopment of the site into the retail pharmacy two 8,000-gallon  underground storage tanks (USTs)and a hydraulic lift were removed from the City Line portion of the site.  The groundwater impacts were attributed to a previous set of USTs removed from the site in 1995 the soil impacts were limited to the vicinity of the hydraulic lift.  Approximately 21.2 tons of petroleum impacted soil was removed from the site during the UST/hydraulic lift removal activities.   

A Remedial Action Workplan (RAW) has been prepared and submitted to the New Jersey Department of Environmental Protection (NJDEP).  The RAW has not yet been approved by the NJDEP.  Petroleum hydrocarbon groundwater impacts have been degrading under natural conditions using monitored natural attenuation and continue to be monitored with quarterly groundwater sampling.  The quarterly groundwater monitoring will continue until two successive quarters are documented with no exceedences of NJDEP ground water quality criteria (GWQC) of the parameters monitored.  CPEG has prepared a Remedial Action Progress Report (RAPR) for the site and will continue to prepare and submit RAPRs once NJDEP approves the RAW.

Also in support of site redevelopment, CPEG provided additional services including the geotechnical subsurface investigation and asbestos survey at the previous site structures in addition to the remedial investigation and environmental site closure to streamline the site development process.

Total cost of project: $181,400

Centralia, Illinois

The CP Environmental Group (CPEG) team conducted Phase I and Phase II Environmental Site Assessments, Ground–Penetrating Radar (GPR) Survey, Storage Tank Closure, Remediation and NESHAP Asbestos Survey on a 1.47 acre parcel.  A Health and Safety Plan was prepared and followed for all intrusive activities.  Removed three previously abandoned gasoline USTs and petroleum impacted soils from a former UST basin documented in a Corrective Action Completion Report (CACR). 

The three gasoline USTs (two 500-gallon and one 1,000-gallon) were discovered near the southwest corner of the site during site redevelopment for the retail pharmacy in June and July 2001.  Approximately 690 tons of impacted soil was removed from the UST area in 2001.  Analytical results indicated that the petroleum impacts (benzene) had been remediated to below state action levels with the exception of a lead concentration in one sample, EP-South SW (8’).

Additional delineation of the lead impact and the excavation of additional material were conducted at IEPA request.  The Addendum to the CACR, dated September 2003, documented collection of six additional soil samples from three locations along the southern property boundary in the vicinity of the former UST excavation.  The soil borings were advanced south, southeast and southwest of the verification soil sample that had been found to contain elevated lead.  Soil samples were collected for analysis from 8 feet below ground surface (bgs) and 16 feet bgs in each of the three borings.  These depths correlate with the depth of EP-South SW (8’) and the bottom of the boring to assess for vertical migration.  Analytical results of the lead analysis indicated that the lead impacts identified in soil sample EP-South SW (8’) was limited to a small portion of the former UST basin excavation sidewall.  Additional soil was excavated during October 2004 to remove the soil containing elevated lead and the results are documented in a CACR addendum dated November 23, 2004.  Site Closure was obtained under TACO, with a No Further Remediation letter issued by IEPA in February 2005.

TolTest/CPEG addressed environmental issues so that the developer could proceed with the redevelopment of the site with the least possible delay to the construction schedule.  Additional soil impact delineation in 2003 and additional soil remediation was completed in 2004.  Work efforts directed in the best interest of the client with concentration on timeliness, quality and cost control.

Environmental, Asbestos and Geotechnical Services in Support of Brownfield Site Redevelopment

RETAIL FACILITY

North Arlington, New Jersey

The CP Environmental Group (CPEG) team was hired to perform environmental, asbestos, and geotechnical services in support of the redevelopment of a 1.34 acre site consisting of two parcels, the former North Arlington Motors (NAM) (used automobile sales) and the former Eagan’s Restaurant (Eagan’s) into a retail pharmacy.  The NAM used automobile sales lot had been a retail gasoline service station since at least 1920.  The restaurant had occupied its portion of the site since 1922. 

Subsurface investigations identified soil and groundwater impacts including petroleum hydrocarbons (gasoline) and chlorinated hydrocarbons.  During redevelopment of the site into a retail pharmacy a total of seven underground storage tanks (USTs) were removed.  Approximately 1,224 tons of petroleum impacted soil was removed from the site during the UST removal activities.   

A Remedial Action Workplan (RAW), Preliminary Assessment and Site Investigation Report has been prepared and submitted to the New Jersey Department of Environmental Protection (NJDEP).  The RAW was approved by the NJDEP.  Groundwater impacts petroleum hydrocarbons and chlorinated hydrocarbons have been degrading under natural conditions using monitored natural attenuation and continue to be monitored with quarterly groundwater sampling.  The quarterly groundwater monitoring will continue until two successive quarters are documented with no exceedences of NJDEP ground water quality criteria (GWQC) of the parameters monitored. 

CPEG continues to prepare Remedial Action Progress Reports for the site in accordance with NJDEP’s approved RAW.

Also in support of site redevelopment, CPEG provided additional services including the geotechnical subsurface investigation and asbestos survey at the previous site structures in addition to the remedial investigation and environmental site closure to streamline the site development process.

Total cost of project: $194,800

Cambridge, Ohio

The CP Environmental Group (CPEG) team was hired to perform environmental, asbestos, and underground storage tank (UST) removal services in support of the redevelopment of a 1.11 acre site consisting of eleven individually owned parcels into a retail pharmacy.  The parcels included an Ohio State University extension office, a hair salon/residence, Smokey’s Tobacco shop, a half-way house, three residences and three vacant parcels.

The Phase I ESA indicated that the Smokey’s Tobacco Shop had been a small market combined with a gasoline filling station (four gasoline USTs) and that the Ohio State Extension office had been a funeral home.  An asbestos survey was conducted concurrently with the Phase I ESA on the site properties to evaluate the potential for asbestos containing materials that would require abatement prior to the demolition of the structures.  The Phase II ESA included a geophysical survey to identify anomalies that could be abandoned underground storage tanks on the site.  The electromagnetic (EM) survey identified likely buried metallic objects in the north east portion of the Smokey’s portion of the site.  Soil and groundwater sampling were also conducted in the vicinity of the buried anomaly at Smokey’s and in the vicinity of the former funeral home.  No soil or groundwater impacts were identified in samples collected during the Phase II ESA.  The removal of the suspected USTs was recommended. 

The geophysical EM anomaly was excavated during June 2004 and four USTs ranging in size from 150-gallons to 1,000-gallons were uncovered.  The four USTs were removed on June 22, 2004, in accordance with the Ohio Department of Commerce, Division of State Fire Marshal, Bureau of Underground Storage tank Regulations (BUSTR) requirements.  Analytical results from UST closure samples collected following the removal of the USTs indicated that there were no impacts that exceeded BUSTR action levels.  CPEG prepared and submitted the UST Closure Report form to BUSTR along with a request for No Further Action (NFA) on August 30, 2004.  BUSTR approved the report and granted NFA status on September 16, 2004.

Also in support of site redevelopment, CPEG provided additional services including an asbestos survey of the existing site structures in addition to the Phase I and Phase II ESA and UST closure activities to streamline the site development process.  The asbestos survey was able to identify those building materials that were positive for asbestos so they could be properly abated and disposed of prior to the demolition of the site buildings. 

Total cost of project: $28,500
