EXHIBIT C
ACTIVITY AND USE LIMITATION OPINION
Roundhouse Parking Lot,Northampton,Massachusetts
DEP Site #1-14222
While not required by the Massachusetts Contingency Plan, 310 CMR 40.0000, this Activity and
Use Limitation (AUL)Opinion has been prepared voluntarily for a parcel of land owned by the
City of Northampton,located on Crafts Avenue, Northampton, Massachusetts, Hampshire
County, Massachusetts 01060 (the “Property”or the “Subject Property”; see Exhibit A-1),
identified by the City of Northampton Tax Assessor as Map 31D, Lot 246 .[Note to the City:
This AUL is intended for the eastern portion of Lot 246 which the City will continue to own
after Lot 246 has been subdivided,and the western portion of the Lot has been sold to the
PVHG. Following the subdivision, this voluntary AUL will apply to the whole of the parcel
retained by the City].An AUL is not required for this parcel because all the MGP residuals
found on this parcel are greater than 15 feet below the ground surface. [See 310 CMR 40.1012
(3)]This AUL is being placed on this property voluntarily to advise current and future property
owners and any persons holding an interest in the property of the presence at depths greater than
15 feet below the ground surface of residuals from the former Northampton Gas Light
Company’s manufactured gas plant (MGP).The MGP had been located on land abutting the
northern boundary of this parcel. This voluntary AUL has been prepared in accordance with the
requirements of 310 CMR 40.1074.As of the date of this Activity and Use Limitation Opinion,
the property is zoned “Central Business ,” which permits commercial and residential use.
Background
The parcel of land subject to this AUL is situated along the western side of Old South Street ,
directly south of the former Northampton Gas Light Company MGP, which is described further
in the following sections.MGP residuals attributable to the release identified by the
Massachusetts Department of Environmental Protection (MassDEP) as Release Tracking
Number (RTN) 1-14222 have been identified within groundwater and subsurface soils (i.e.,
greater than 15 feet below ground surface [ft bgs])beneath the Property.
The property on which this AUL is being implemented is currently utilized as an asphalt-paved
parking lot, hereinafter referred to as the “Roundhouse Parking Lot”. The Property was formerly
occupied by the New York, New Haven and Hartford Railroad tracks and by the Mill River .The
railroad tracks, originally constructed in the early 1850’s,ran east-west through the property.
The Mill River was formerly located directly south of the railroad tracks. The river, which
flowed from west to east, was diverted in 1940 for flood protection purposes,and its former
channel was filled. The former river channel was approximately 30 feet in width.
Disposal Site History
In 2001, a release of oil and hazardous materials (OHM) was identified at properties to the north
of the S ubject Property.The area to the north of the Subject Property includes a portion of the
Roundhouse Parking Lot, the Roundhouse Office Building, and the Pulcharski Municipal
Building,all of which were formerly occupied by the Northampton Gas Light Company’s MGP
and the company’s offices.The MGP was initially developed around 1855 ,coinciding with the
construction of the New Haven and Northampton Railroad. Much of the part of the Disposal Site
(“the Site”) where the release(s) of OHM occurred was used for the manufacturing, storage,and
distribution of coal, water, and oil gas.Gas production was discontinued in 1951.Most of the
gas manufacturing structures formerly present on the property were demolished in 1962.The
property occupied by the MGP and its remaining structures were donated to the City in 1973.
Environmental assessments have been conducted at the Site since 2001 in accordance with the
requirements of the Massachusetts Contingency Plan (MCP).Bay State Gas Company
conducted all of the MCP-required assessment and remediation performed at the Site.The Phase
II Comprehensive Site Assessment resulted in a detailed conceptual site model for the Site.
Some MGP-impacted material, including ash, coal, and clinkers, was likely used as fill material
within the footprint of the former facility or was graded and re-worked around the facility.Tar
and oily MGP residuals also were likely released from containers or through foundations into the
subsurface.The oily MGP residuals, being denser than water,migrated downward through the
heterogeneous subsurface fill and glacio-fluvial sand and gravel underlying the facility.Clay and
other fine-grained, impermeable soil are present below the sand and gravel at depths ranging
from 10 to 35 feet below ground surface. Where the dense oil encountered these fine grained
clay or fin e-grained soils ,it either accumulated at that location or migrated laterally along the
upper surface of the clay/soils.This is the likely mechanism by which the residuals came to be
located on the Subject Property.Some MGP constituents have dissolved in groundwater and
have migrated advectively with the natural groundwater flow.[Note: The “MCP” is the
Commonwealth of Massachusetts’ code of regulations (310 CMR 40.0000) for the notification,
assessment and cleanup of disposal sites where a release of Oil or Hazardous Materials has
been detected.]
Reason for Activity and Use Limitation
An AUL is not required by the MCP for this property because MGP residuals attributable to the
Site are only located at depths greater than 15 feet bgs beneath the Property as described in detail
in the Phase II report. However,to limit future potential exposures to subsurface soil and/or
groundwater greater than 15 feet bgs on the Property,certain activity and use restrictions will be
placed on the Property.
The majority of soils beneath the Property between the ground surface and approximately 10 feet
below ground surface (ft bgs) consist of historic fill materials, with a confining clay layer located
beneath the fill soils at depths ranging from 20 to 30 ft bgs.Since the elevation of the railroad
bed was at least as high as the current grade, it is reasonable to infer that the fill materials in the
location of the railroad tracks coincide with or pre -date the construction of the railroad.The fill
in the river was presumably added around 1940.
Average depth to groundwater beneath the Property ranges from 15 ft to 17 ft bgs .As previously
discussed, the mechanism of deposition of the MGP materials currently located beneath the
urban fill soils either occurred through lateral migration from the MGP along the upper surface
of the clay layer or through advective migration with the natural groundwater flow.Soils located
between the ground surface and the water table (which consist primarily of historic fill materials)
are not included in the disposal site as these soils have not been impacted by the release
associated with RTN 1-14222.As such, the water table has been designated as the marker below
which certain activities will be required to limit potential exp osures to MGP residuals through
the implementation of an AUL.
Specifically, this AUL will prevent exposures of certain receptors (i.e. children, trespassers,site
workers and residents) to MGP residuals in the subsurface beneath the water table.A Method 3
risk characterization was completed to evaluate potential risks associated with the MGP-related
compounds in the groundwater and subsurface soil beneath the water table . There are no risks of
harm to human health posed by the MGP residuals that are present at the disposal site under
current and reasonably foreseeable future activities and uses because h umans are not able to
contact the MGP residuals in their present location.Implementation of this AUL will limit
future potential exposures to MGP residuals that are present at the Property at depths below the
water table elevation.[Note: The MCP allows a risk characterization for a disposal site to be
performed by one of three methods: Method 1, which involves a comparison of soil and
groundwater contaminant concentration measured at a site to existing numerical standards;
Method 2, which involves comparison of soil and groundwater contaminant levels measured at a
site to more site-specific numerical standards derived for a particular site; and Method 3,which
involves a quantification of total site risk considering on-site receptors, assumed exposure
scenarios, and contaminant levels measured at the site.]
1.Permitted Activities and Uses
The following activities and uses are permitted at the Property:
(i) Excavation and/or removal of potentially MGP-contaminated subsurface soils (below
the water table greater than fifteen (15)feet below ground surface)and associated
handling and processing (e.g. size reduction, etc.) associated with limited short-term
(three months or less) construction work, provided that it is conducted in accordance
with the performance standards of the MCP. Such activities must be conducted in
accordance with the performance standards set forth by the MCP and conducted under
the direction of a Licensed Site Professional (LSP).[Note: An LSP is a person that the
Commonwealth of Massachusetts has determined has the appropriate education and
experience to manage the assessment and remediation of sites pursuant to the MCP
without the direct oversight of the Massachusetts Department of Environmental
Protection (MassDEP)].Excavation activities must be conducted in accordance with the
Soil Management Procedures pursuant to 310 CMR 40.0030, and/or all applicable
worker health and safety practices pursuant to 310 CMR 40.0018;
(ii) Activities and uses which are not identified by this Notice as being inconsistent with
maintaining a condition of No Significant Risk; and
(iii) Such other activities and uses which, in the Opinion of an LS P, shall present no
greater risk of harm to health, safety, public welfare, or the environment than the
activities and uses set forth in this paragraph.
2.Activities and Uses Inconsistent with the AUL Opinion.
Activities and uses which, if implemented at the Property, may result in a significant risk of harm
to human health, safety, public welfare, or the environment are as follows:
(i)Activities and/or uses which involve the removal and/or disturbance of the MGP-
contaminated soil located beneath the water table without prior development of a Soil
Management Plan and a Health and Safety Plan in accordance with Obligations (i) and
(ii) of Paragraph 3 below;and
(ii) Relocation of the MGP-contaminated soil from beneath the water table o n the
Property, unless an LSP renders an Opinion which states that such relocation is
consistent with maintaining a condition of No Significant Risk.
3.Obligations and Conditions Set Forth in the AUL Opinion.
If applicable, obligations and/or conditions to be undertaken and/or maintained at the Property to
maintain a condition of No Significant Risk as set forth in this AUL Opinion shall include the
following:
(i) A Soil Management Plan must be prepared by an LSP and implemented prior to the
commencement of any activity that will disturb the MGP-contaminated soil located
beneath the water table.The Soil Management Plan must be prepared by an LSP and
implemented prior to the commencement of any activity at the Property that involves the
disturbance, excavation and/or removal of OHM-impacted soil, with the exceptions
described in Paragraph 1 above.The Soil Management Plan should describe appropriate
soil excavation, handling, storage, transport, and disposal procedures in accordance with
the provisions of the MCP cited at 310 CMR 40.0030 et seq. and appropriate
groundwater handling, storage, and disposal procedures in accordance with the provision
of the MCP cited at 310 CMR 40.0040 et seq.The Soil Management Plan should
include a description of the engineering controls and environmental monitoring
procedures, if any, necessary to ensure that workers and receptors in the vicinity are not
affected by fugitive dust or particulates from the Property.On-site workers must be
informed of the requirements of the Soil Management Plan, and the plan must be
available on-site throughout the course of the project;
(ii) A Health and Safety Plan pursuant to 310 CMR 40.0018,must be prepared by a
certified Industrial Hygienist or other qualified individual sufficiently trained in worker
health and safety requirements and implemented prior to the commencement of any
activity at the Property which involves the disturbance, excavation and/or removal of
OHM-impacted soil, with the exceptions described in Paragraph 1 above.The Health
and Safety Plan should specify the type of personal protection (i.e., clothing, respirators),
engineering controls, and environmental monitoring (if any) necessary to prevent worker
exposures to OHM-impacted soil.Workers must be informed of the requireme nts of the
Health and Safety Plan, and the plan must be available on-site throughout the course of
the project;and
(iii) Response actions must be conducted in accordance with the Massachusetts
Contingency Plan, 310 CMR 40.0000, should an LSP Opinion rendered pursuant to
Obligation (i) conclude that future Property uses and activities, including exposures
associated with future building construction, are inconsistent with maintaining a
condition of No Significant Risk.
