Former MAD Depot—Locust St.
Solid Waste Dumping Ground
CAD Final Closure —Extension of Time
BWPSW25
Transmittal#X262791
Dear Mr.Cavicchi:
On July 25,2017,the Massachusetts Department of Environmental Protection(MassDEP)issued to the
Massachusetts Department of Transportation(MassDOT)a revised Corrective Action Design(CAD,or Final
Closure)permit approval(the Revised CAD Permit)for remediation of the solid waste dumping ground(the
dumping ground)at the former MassDOT Depot, located off Locust St. in Northampton,MA.The Revised
CAD Permit required completion of Final Closure activities by November 15,2018.
On November 7,2018 MassDEP received a written request from MassDOT,for extension of the Final
Closure deadline until November 30,2019. The request outlines the reasons for the need for a time
extension,including funding constraints and wetlands permitting issues. On December 13,2018,MassDEP
received from MassDOT copies of the following updated wetlands permits for the work: Order of
Conditions;Army Corps Permit;and Water Quality Certification.
MassDOT states that the bidding process for the Final Closure work will be completed by the Spring of 2019,
construction activities will begin in the late Spring of 2019,and all Final Closure work will be completed by
November 30,2019
Outlined below is MassDEP's revised CAD permit approval approving the time extension.
This Information is available in alternate format.Contact Michelle Waters-Ekanem,Director of Diversity/Civil Rights at 617-292-5751.

Revised CAD Permit Approval
The original September 8,2014 CAD application included the following:
• A completed BWPSW25 application form and transmittal form;
• Text describing the proposed revised remedial activities to be performed as part of the final closure
of the dumping ground;
• Engineering plans,cross-sections and details;
• A copy of the approved Order of Conditions for the final closure of the dumping ground,issued
April 24,2014 by the Northampton Conservation Commission;
• A copy of the U.S.Army Corps of Engineers General wetlands permit,dated April 7,2014;and
• A copy of the MassDEP Water Quality Certification for the work,dated May 7,2014.
The dumping ground is about 0.7 acres in size and 5 to 10 feet thick, located at the northwestern portion of
the MassDOT property,along both sides of the small stream there. The small stream enters the site at the
northern property boundary via a culvert,flows above-ground for about 150 feet,then is culverted under the
southern portion of the MassDOT property and Locust Street,and discharges in the Smith Vocational pasture
just south of Locust Street. Test-pitting in the dumping ground showed that the material within it is primarily
soil fill,including street sweepings,with secondary amounts of concrete and asphalt rubble,wood,metal and
glass. Groundwater monitoring wells TB-121 and TB-221 are located immediately downgradient(south)of
the dumping ground,and monitoring well MW-3 is located crossgradient(southeast)of the dumping ground,
near the MassDOT salt shed,which apparently is still used. There are no public or private water supply wells
in the vicinity of the site,and all properties in the surrounding area are serviced by the City of Northampton's
municipal water supply system.
The Qualitative Risk Assessment for the dumping ground,contained in the CSA Report, states that:
• The groundwater and surface water at and downgradient of the dumping ground poses No
Significant Risk to human health and the environment;
• The slightly elevated lead level at the Downstream sediment sample on-site and the low levels of
TPH at both sediment locations do not pose a significant risk to human health or the environment;
• Landfill gas is not being generated by the dumping ground and is not a risk to human health or the
environment;and
• Overall,"human health and environmental impacts from the solid waste area are limited and the
present risk posed by the site is considered to be low'.
Summary ofPro.osed CAD Work
Final Closure activities will consist of the following:
• Prior to any remedial work,erosion and sedimentation controls will be placed around the limits of
work,as required by the Conservation Commission.
• The entire volume of the solid waste dumping ground will be excavated down to underlying
native soil, and all solid wastes will be screened from the excavated soils using a mechanical
screen.
• All solid wastes screened or otherwise removed from the excavation will be disposed or
recycled at permitted,off-site disposal/recycling facilities.
• Screened soils from the excavation will be placed in 500 cubic yard(cy)piles and one
composite sample will be obtained from each 500-cy pile and analyzed for volatile organic
compounds(VOCs)by EPA Method 8260, RCRA 8 metals,Extractable Petroleum Hydrocarbons
•

(EPH)by MassDEP ORS Method,and Polychlorinated biphenyls(PCBs)by EPA Method 8280.
• Screened soils which are below the MassDEP's Bureau of Waste Site Cleanup(BWSC)S-I,
GW-1 soil standards will be placed back into the excavated area.
• Screened soil which is above the S-1,GW-1 soil standards will be removed under Bills of
Lading to off-site,permitted landfills for proper reuse as alternate daily cover material.
• For parameters where no S-1,GW-1 standards are available,the MassDEP BWSC Reportable
Concentration S-1 (RCS-1) soil standards will be utilized to determine the disposition of
screened soils.
• Following the excavation of the entire solid waste mass of the dumping ground and prior to the
replacement of screened soils as outlined above,composite soil samples will be obtained from
each 50-foot by 50-foot area of the base of the excavation,to determine if backfilling can occur.
Each of these composite soil samples will be analyzed for VOCs by EPA Method 8260,RCRA 8
metals,EPH by MassDEP ORS Method,and PCBs by EPA Method 8280.Backfilling will not
occur unless and until the basal soil samples meet the S-1, GW-1/RCS-1 soil standards.
• The excavation will be backfilled with the excavated soils meeting S-1, GW-1 soil standards and
clean soil and topsoil,will be graded to a minimum 2%topslope and maximum 2:1
horizontal:vertical slope, and wetland restoration will be completed as outlined in the Wetland
Restoration Plan and as approved by the Order of Conditions.
• A Closure Certification Report will be completed.
MassDOT had stated that the Final Closure work would be completed in 2015.
