A vapor mitigation system shall be presumed to not be required if the building design will eliminate the potential pathway by using an open-air first level or a first level parking garage. 3. Obligations and Conditions. The following obligations and/or conditions are necessary and shall be undertaken and/or maintained at the Portion of the Property to maintain a Permanent Solution and a condition of No Significant Risk: d (i) An LSP shall render an opinion stating whether a vapor mitigation measure is needed to prevent a significant risk to human health, safety or welfare of future occupants of any proposed building. A vapor mitigation measure shall consist of [a] a vapor barrier and/or a sub slab depressurization system installed below a building concrete slab floor mitigating the potential vapor intrusion pathway as approved by an LSP; or [b] an equivalent measure mitigating the potential vapor intrusion pathway as approved by an LSP; (ii) A vapor mitigation measure, if present, must be maintained to prevent future exposures to underlying vapors. Repair/replacement of the vapor mitigation measure must be completed within sixty (60) days following identification of disrepair or damage; t s (iii) Inspection frequency and associated record-peeping activities for the vapor mitigation measure, if present, shall be determined by an LSP. An LSP must evaluate vapor mitigation measure operation data and/or soil gas or indoor air data, and render an Opinion as to whether site conditions, activities, and/or uses associated with the building potentially pose a significant risk of harm to i human health. The frequency of these evaluations and LSP Opinions shall be specified in the design of the vapor mitigation measure; (N) A Soil Management Plan describing soil management and disposal, if necessary, and a I-3ealth and Safety Plan must be approved by an LSP and implemented prior to the commencement of any activity that will disturb the impacted soil located below elevation 106 feet (NAVD88 datum), which is more than 15 feet below the existing ground surface at the time this AUL was recorded; - (v) Response actions must be conducted in accordance with the Massachusetts Contingency Plan, 310 CMR 40.0000, should an LSP Opinion rendered ' pursuant to Obligation 3 (iii) conclude that future site uses and activities, including exposures associated with future building construction, are inconsistent with maintaining a condition of No Significant Risk;and (vi) Any MGP-impacted.soil encountered during work on the property shall be managed in accordance with the site-specific Soil Management Plan and Health I AUL Forms 390 CMR 40.9099 I I I MGP- and Safety Plan. The determination as to whether or not soil at the site is impaeted soil shall -be made based on physical and olfactory evidence of the presence of tar, tar oils, blue'or greenish soil or stones, and/or blue wood chips or olfactory indications of a characteristic coal tar odor (naphthalene odor). Visual and olfactory evidence can be a better indicator of source than the detection of PAHs by chemical analysis and the detection of PAHs by chemical analysis is not,by itself,necessarily a reliable indicator of the presence of MGP- impacted soil. a 4. Provo ed Changes in Activities and Uses. Any proposed changes in activities and uses.at the Portion of the Property which may result in higher levels of exposure to oil and%or hazardous material than currently exist shall be evaluated by a Licensed Site ProiJessional who shall render an Opinion, in accordance with 310 CMR 40.1080, ias to whether the proposed changes are inconsistent with maintaining a Permanent Solution and a condition of No Significant Risk.

Soil assessment on the Property included collection and visual evaluation of shallow soil (0 to 10 feet below ground surface), and limited chemical characterization of shallow soil because MGP residuals were not present above the water table and MGP operations did not occur on the Property. The shallow soils consist of urban fill materials. I The Disposal Site extends laterally across the Property as shown on Exhibit B.The vertical.extent of the Disposal Site extends from the top of water table to the vertical downward extent of MGP ±' impacted soil and/r groundwater,typically at the depth(20 to 35 feet below ground surface) of the top of the clay surface that comprises the former bottom of Glacial Lake Hitchcock. MGP residuals migrated to areas outside the former MGP operations via groundwater migration or oil- like material migrating on top of the underlying clay, an impermeable boundary. Urban fill is commonly present in the unsaturated zone in areas outside the former MGP operations. The Portion of the Property on which this AUL is being implemented is currently utilized as an asphalt-paved municipal 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 northern portion of 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. Site History The Northampton Gas Light Company MGP was initially developed on land west of the Property in about 1855. The MGP operated until 1951. Most of the gas manufacturing structures formerly present north ofthe Property were demolished in 1962.The MGP property and remaining structures were donated to the City in 1973. I Environmental assessments conducted at the Disposal Site were completed in accordance with the requirements of the Massachusetts Contingency Plan (MCP). The Phase 11 Comprehensive Site. Assessment resulted in a detailed conceptual site model for the Disposal 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 to the west of the Property.Tar and oily MGP residuals also were likely released from containers or through foundations into the subsurface to the west of the Property.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 20 to 35 feet below ground surface. Where the dense oil encountered these fine grained clay or fine-grained soils, it either accumulated at that location or migrated laterally along the upper surface of the clay/soils,impacting the subsurface beneath the Property and other Page 1 of 3 properties south and east of the MGP.Some MGP constituents have dissolved in groundwater and have migrated advectively with the natural groundwater flow. Following Phase II assessment activities,remediation activities were primarily conducted on the land west of the Property(the northern portion of the Roundhouse Parking.Lot)including: i • Excavation of a minimum of three feet of soil over the portion of the Roundhouse Parking Lot formerly occupied by the MGP facility.Installation of a constructed barrier consisting of a marker layer(orange-colored geotextile)and a three-foot thick clean soil layer above the marker layer was completed in this area. • Excavation and off-site disposal of soil, bricks, and coal tar residuals present within the former gas holders,tar wells; a far separator,and drip pots as well as excavation and off- site.disposal of impacted soil adjacent to these structures. • Relocation/replacement of all shallow and deep utilities that pass through the former gas ' holder to the west of the Roundhouse Building. • Excavation along shallow utilities on the northern portion of the Roundhouse Parking Lot adjacent to the Roundhouse Building to install remediated utility corridors. - Following completion afthe remediation activities,a Phase IV Remedy Inspection and Completion Report and`Class C Response Action Outcome(RAO)Statement were completed.The.Substantial Hazard Evaluation within the Class C RAO Statement assessed the exposure scenario for a current visitor/trespasser and current utility worker on the Property. The Substantial Hazard Evaluation concluded workers maintaining the current asphalt pavement surface of the municipal parking lot on the Property have no exposure because of the depth of the MGP residuals.The cumulative cancer and non-cancer risks for the visitor/trespasser and utility worker do not exceed risk limits specified at 310 CMR 40.0993(6). Under the.MCP as revised in 20.14, a Permanent Solution with Conditions will be achievable for the Site or portions of the Site once AULs are,in place. The overall Site strategy is to achieve permanent closure(i.e.,Permanent Solution with Conditions),although actual risks will not change in moving from temporary closure.status (i.e., Temporary Solution with Conditions, formerly a Class C Response Action Outcome Statement). Some AU.Ls have been placed on portions of the site, including on the City-owned Roundhouse Parking Lot, the former location of the MGP. Closure documents and additional Site information are,-and if updated will be, available on the Massachusetts Department of Environmental Protection's Bureau of Waste Site Cleanup website under the Release Tracking Number for the Site of RTN 1-14222. Reason for Activity and Use Limitation To limit future.potential exposures on the Portion of the Property subject to the AUL(see Exhibit A-1), certain activity and use restrictions will be placed on the Property. Specifically,this AUL will prevent exposures of certain receptors(i.e.trespassers,future facility workers,utility workers, future construction workers,and future residents)to MGP residuals in the subsurface.-A Method 3 risk characterization was completed to evaluate potential risks associated with the MGP-related compounds in the subsurface soil and groundwater.
