15.0 PUBLIC INVOLVEMENT
ECR has provided letters to the Mayor of Northampton, the Board of Health, and the owner of 480-
492 Pleasant Street (see Appendix G) to notify them of the existence and availability of this PSC.
16.0 CONCLUSIONS
The findings and conclusions of this Permanent Solution with Conditions (PSC) Statement are briefly
summarized as follows:
• The Site, located at 459 Pleasant Street in Northampton (the Property), is currently occupied
by a used car dealership (Pleasant Journey Used Cars) and owned by Mr. Robert Kalish.
The Site is identified by the Massachusetts Department of Environmental Protection
(MassDEP) under Release Tracking Number (RTN) 1-705. The Site has been impacted by
petroleum releases originating from the former use of the Property as a gasoline service
station between 1932 and 1984.
• The 459 Pleasant Street Property includes two buildings that have existed since
approximately 1932: a one-story garage used for automobile maintenance, and a one-story
building utilized as office space by Pleasant Journey Used Cars. The garage building was
substantially rebuilt in approximately 1980.
• The Site is located in a commercial area of Northampton. Drinking water is provided by the
City of Northampton's municipal water supply system. Private wells were not identified in the
vicinity of the Site. The Site is not located in protected water supply area (e.g., Zone II).
• The 1.25 acre Site includes portions of two properties located across Pleasant Street. These
properties are at 480 and 492 Pleasant Street and are owned by ES 480 Pleasant St LLC do
Suher Properties. Pro Lube Auto Center operates at 480 Pleasant Street, and a car wash and
office exist at 492 Pleasant Street.
• Prior to 1955, Pleasant Street did not exist, and the properties at 459 Pleasant Street (the
Property) and 480 Pleasant Street were contiguous and under the common ownership of the
former gasoline station owner. The gasoline service station dispensed product from a
dispenser located on the Conz Street side of the station. Gasoline appears to have been
supplied from storage tanks located on what is now 480 Pleasant Street. These tanks were
removed in 1984. Data obtained and reviewed by ECR did not indicate the existence of a
significant release from these tanks.
• After the construction of Pleasant Street in 1955, it appears that additional dispensers were
installed on the eastern portion of the Property to served traffic on Pleasant Street. It appears
that the new dispensers were served by tanks installed on the Property.
• Soils on the Property generally consist of silt, fine sand, and some coarse gravel with medium
coarse sand and traces of fine gravel present at greater depths. Bedrock outcrops were not
observed on or in the vicinity of the Site, and bedrock was not encountered during subsurface
explorations.

• Groundwater depths on the Property generally ranged between 7.5 and 10 feet below grade,
with occasional deeper readings. Observed depths on the properties across Pleasant Street
were typically between 8 and 10 feet below grade. Groundwater flow direction has
consistently been measured to the east, i.e., from the Property toward the properties at 480 and
492 Pleasant Street.
• Gasoline impacts were first detected in 1988 at the 492 Pleasant Street property (i.e., across
Pleasant Street from the former service station at 459 Pleasant Street). Subsequent
investigations led to the discovery of greater gasoline concentrations at the 459 Pleasant
Street Property. LNAPL was later reported in monitoring wells at 459 Pleasant Street and the
western portions of the 480 Pleasant Street property.
• The primary source of gasoline in soil and groundwater at the Site is identified as the former
UST system at the Property. Results of investigations conducted by ECR and previous
consultants concluded that the former pump island area on the eastern side of the Property
was the area of greatest impact.
• Remedial actions at the Site have included removal of soil in the vicinity of former tanks at
480/492 Pleasant Street, manual bailing of gasoline from monitoring wells between 1992 and
approximately 2000, and the operation of groundwater and vapor extraction systems between
approximately 2003 and 2010 that reportedly recovered over 700 gallons of gasoline. These
actions coupled with the effects of natural attenuation processes have produced significant
decreases in gasoline component concentrations over time. LNAPL has not been detected in
Site monitoring wells since March 2004, and all but two wells have achieved results below
Method 1 standards for gasoline constituents. However, gasoline compounds remain in soil
and groundwater, particularly in the vicinity of the primary source areas.
• Pursuant to MassDEP's 2015 audit of response actions at the Site, ECR conducted additional
work including the evaluation of the potential occurrence of recent gasoline releases. The
results of a soil vapor survey, analysis of soil and groundwater samples, and evaluation of
Site historical information did not indicate the existence of recent releases of gasoline.
• A combined Method 1/Method2/Method 3 Risk Characterization concluded that a Condition of
No Significant Risk to human health has been achieved at the Site. Imminent Hazards and
significant risks to safety, public welfare, and the environment were not identified. These
conclusions are contingent on adherence to an Activity and Use Limitation (AUL) that restricts
future use of the Property as a residence, school, nursery, park, playground, daycare center,
or other use where children may become significantly exposed to Site soils. The AUL also
imposes requirements for future activities that could involve exposure to contaminated media,
and contains obligations and conditions that are necessary to maintain a condition of No
Significant Risk. The AUL applies only to the 459 Pleasant Street Property.
• A site-specific evaluation concluded that it is infeasible to conduct additional remediation to
achieve or approach background levels for residual constituents of concern.
