The AUL area is the approximately 1,260-square-foot area situated in the immediate vicinity of the hydraulic lift system located in the southern portion of the vehicle maintenance garage, �s her6in4f t)efthd-"P-orti+ FfWe_13T0 Tlit-f AM-0PW1 e ap -don the results of response actions conducted by Coneco between June 2012 and December 2024. Release Hu'Cory and S mmary 4,f'Completed Respome Actions In the spring of 2012,MECD personnel noted that a hydraulic vehicle lift system located in the southern portion of the vehicle maintenance garage at the Property ywas malfunctioning. Upon '� inspection of the hydraulic lift system and the associated 200-gallon aboveground storage tank • (AST)located in the southeastern portion of the garage,MECD noted a drop in the hydraulic fluid level of the AST;however,they were unable to determine the cause of the drop. MECO contracted a service firm to inspect and evaluate the fift system and perform repairs,if necessary. Upon further inspection,it was determined that the system had a pressure lass due to a leak somewhere in the system;however,the specific location of the leak could not be determined. No avidencc of a rolease to the environment could be determined at that time,as the leak may have occurred into the lift pit or piston wall. Therefore,MECQ contracted Coneco to evaluate subsurface conditions and determine whether a release of hydraulic oil to the environment had occurred from the hydraulic lift system. In August 2012,two groundwater monitoring wells were installed near the hydraulic lift system. Dn September 5;2012,during initial gauging activities,light non-aqueous phase liquid(LNAPL) having a me&sured thickness of 23 inches was detected within the groundwater monitoring well identified as Ew103/Mw103,located adjacent to the hydraulic lift within the vehicle maintenance garage. In addition,LNAPL having a measured thickness of three inches was detected in the newly-installed groundwater monitoring well identified as CMw-01. Therefore, a 72-hour reportable condition,as defined in 310 CMR 44.03 13(1),was identified at the Property. On behalf of MECO,Coneco verbally notified Mr.victor Fonkem of the MassDEP- ` Northeast Region Office(MassDEP-NERO)of the reportable condition at approximately 3:25 P.M.on September S.2012. At that time,Mar.Fonkem provided verbal approval to conduct Immediate Response Action(IRA)activities consisting of assessment only. The release was � subsequently assigned Release Tracking Dumber(R' 3-31085. Additional response actions have included periodic passive recovery of LNAPL via hand bailing and the use of oil-absorbent socks,as well as an additional subsurface investigation consisting of the installation of four soil borings and the installation of four additional monitoring wells. Quarterly groundwater sampling was conducted at the Portion of the Property from November 2012 to January 2022. t } t Bk 18432 Pg303 #19598 On behalf of MECC,Coneco has previously submitted numerous MCP-related reports to MassDEP in relation to RTN 3-31085. Rey documents include the following: A Release Notification Form,IRA Plan,and Modified IRA Plan submitted on November � 5,2012; + IRA Status Reports with Remedial Monitoring Deports(RNIRs)submitted in accordance with 310 CMR 40.0425; �► Phase I-Initial Site Investigation and Tier II Classification Report submitted on September 5,2013; * Phase II Comprehensive Site Assessment(CSA)Report submitted on September 6,201 6; • IRA'Completion Deport,Final RMR,Phase III-Remedial Actioh Plan(RAP),and Phase IV-Remedy Implementation Plan submitted S - rt - �` ��ierClassifickalFon F,�tens10 s su Pied on Jul y 23,2018,July 23,2020,and July ,23 r 2022; Temporary • P r a p rary Solution Statement submitted on September 12,2018,and � Phase IV Status Reports,Post-Temporary Solution Status Reports,and Interim RMRs, submitted uM accordance with 310 CMR 40.0977 and 310 CMR 40.0898. As detailed in the abovementioned regulatory reports,the contaminants of concern(CoCs)at the Disposal Site have been identified as extractable petroleum hydrocarbons(EPIC)carbon fraction ranges in soil and groundwater,including hydraulic oil LNAPL observed in certain on-site monitoring wells(i.e.,HW 1011MW 101,BW 143/M' 103,BW I04/MW104,CMw-01,and CMW-02),and air-phase petroleum hydrocarbons(APH)detected in sub-stab soil gas. To assess the current and future risk of harm to human health,public welfare,safety,and the environment posed by the presence of residual LNAPL,EPH in soil and groundwater,and APH in soil gas at the Portion of the Property,Coneco performed a Method 3 Risk Characterization in , accordance with the MCP(310 CMR 40.0990). Based on the results of the Method 3 Risk Characterization,a condition of`'No Significant Risl"exists for current activities and uses of the Portion of the Property. Reason �[ ' 'ct�vrty forand Use�rn�ta�on • As previously indicated#the results of the.Medved j Risk Characterization performed for this i Disposal Site indicate that a condition of No Significant Risk exists for current activities and uses of the Portion of the Property.

Therefore,these activity and use scenarios were eliminated from the Method 3 Risk Characterization. To maintain a condition ofNo Significant Risk for future activities and uses,this AU1,which restricts certain future activities and uses as outlined in the Notice of Activity and Use Limitation(Form 1075),must be implemented.
