November 30, 2020 Mr. Leury Perez CommTank, Inc. 84 New Salem Street Wakefield, Massachusetts 01880 Re: Abandoned 275-gallon Capacity Fuel Oil Underground Storage Tank (UST) Closure Report Yarmouth Gardens Motor Lodge 497 Route 28 West Yarmouth, Massachusetts 02673 ECMS Project No. 1076.462 Dear Mr. Perez: Environmental & Construction Management Services, Inc. (ECMS) hereby issues this letter report to CommTank, Inc. (CommTank) outlining the Licensed Site Professional (LSP) review of closure activities for the underground storage tank (UST) at the above referenced Site. Introduction When any UST is permanently "closed" (removed or closed-in-place), Massachusetts law requires that the presence of contamination in the environment be assessed. Specifically, within 24 hours after the removal of the UST, measure for the presence of contamination at locations where it is most likely to be present, as required by Massachusetts Fire Prevention Regulations 527 CMR 9.07(K)(4)). UST Removal Observations On November 17, 2020, CommTank personnel uncovered a portion of soils surrounding a partially buried 275-gallon capacity No. 2 fuel oil UST and removed the single-walled steel UST from the subsurface. This tank was empty of any fuel oil and considered a UST since more than 10% was buried beneath the surface. Refer to CommTank Tank Closure Report and field notes attached as Appendix A. After the removal of the UST, soils collected from the excavation were screened in the field by CommTank personnel for total organic vapors (TOVs) using a RAE Systems MiniRae 2000 photoionization detector (PID). Prior to use, the PID was fully charged and calibrated to 100 parts per million (ppm) isobutylene standard. TOV concentrations ranged from 2.6 to 6.6 ppmv. No petroleum discoloration or obvious petroleum odors were noted or observed by 275-gallon Capacity Fuel Oil UST Closure Report 497 Route 28 – Yarmouth, Massachusetts ECMS Project No. 1076.462 2 Environmental & Construction Management Services, Inc. CommTank personnel during excavation. Refer to Appendix B Photographs for photographs of the UST removal activities on November 17, 2020. For documentation purposes, one (1) soil sample [designated as SW-1] was collected from the area of highest TOV reading from beneath the UST at a depth of 2 foot below grade (bg) by CommTank personnel for delivery under proper chain-of-custody (COC) to ChemServe Environmental Analysts (ChemServe) of Milford, New Hampshire to be analyzed for Massachusetts Department of Environmental Protection (MassDEP) Extractable Petroleum Hydrocarbon (EPH) with target polynuclear aromatic hydrocarbon (PAH) compounds. The results of the EPH fractions and PAH target compounds for post excavation soil sample PB were all detected below their applicable RCS-1, specified in Massachusetts Oil and Hazardous Materials List (MOHML) 310 CMR 40.1600 and 310 CMR 40.0300. Refer to Table 1, Summary of Post Excavation Soil Sample Analytical Data for Extractable Petroleum Hydrocarbons (EPH). A copy of the soil laboratory report is attached as Appendix C. In accordance with the MCP 310 CMR 40.0310, the observed conditions on November 17, 2020 did not meet the notification conditions for either a 2-hour or a 72-hour MADEP notification under the MCP and based on the results of the laboratory analysis of soil did not meet the notification condition(s) for a 120-day release notification. This tank closure was performed in general accordance with the MassDEP preferred method of documentation as outlined in accordance with Commonwealth of Massachusetts Underground Storage Tank Closure Assessment Manual (MassDEP Policy #WSC-402-96) dated April 9, 1996. Conclusions and Recommendations The sampling approach performed for the removal of this UST satisfies the requirement to measure for contamination in accordance with Massachusetts Fire Prevention Regulations 527 CMR 9.07(K)(4). Based upon the observed conditions, there is no indication that a release of oil has occurred in accordance with the MCP 310 CMR 40.0000 and Massachusetts General Law Chapter 21 (MGL 21E). Based on these observations, no further comprehensive response actions in accordance with the requirements of the MCP are deemed necessary. This work was undertaken in accordance with generally accepted consulting engineering practices, and the opinion rendered herein is based upon professional expertise and experience. No other warranty, expressed or implied, is made. 275-gallon Capacity Fuel Oil UST Closure Report 497 Route 28 – Yarmouth, Massachusetts ECMS Project No. 1076.462 3 Environmental & Construction Management Services, Inc.

Any abnormalities to the samples upon receipt would be noted on the enclosed chain of custody document. This report is not valid without a completed chain of custody with the corresponding control number, attached. All samples analyzed by ChemServe are subject to quality standards. These standards are as stringent or more stringent than those established under NELAC, 40 CFR Part 136, state certification programs, and corresponding methodologies. ChemServe has a written QA/QC Procedures Manual that outlines these standards, and is available for your reference, upon request. Unless otherwise stated on the Chain of Custody or within the report, all holding times, preservation techniques, container types, and analytical methods are analogous with those outlined by NELAC. All units are based on “as received” weight unless denoted “dry”. Residual chlorine, sulfite and pH are intended to be performed as an immediate field analysis. Should any of these analyses be performed in the lab instead of in the field it will result in those analyses being performed out of holding time. Acrolein and 2-chloroethylvinyl ether require an additional analysis with an un-preserved sample. If unpreserved vials were not submitted for these compounds then acrolein and 2-CEVE are not reported due to not meeting method requirements, but may be reported as estimated upon request for EPA 624.1 or EPA 524.2. I certify that I have reviewed the above referenced analytical data and state forms, and I have found this report within compliance with the procedures outlined within NELAC. ChemServe’s certified parameter list can be found at http://www.chemservelab.com/Laboratory-Information-and- Documentation.aspx ____________________________________ Jay Chrystal - President/Laboratory Director Date Received:11/23/2020Yarmouth, MAProject Location: Certificate Number 1008 Page 1 of 14 MADEP MCP Analytical Method Report Certification and Case Narrative Job Name: None Lab Number: 20110311 Job Number: None Control Number: 119687 Location: Yarmouth Client: Commtank Sample Matrix: (x) Soil () Groundwater () Drinking Water () Combined MCP SW-846 8260C () 8270D () 8082A ( ) 8081A ( ) 7470/7471 ( ) 9014 ( ) Methods Used 8151A ( ) EPH (x) VPH () 6010C () 7000 series ( ) 7196 ( ) An Affirmative response to questions A through F are required for “Presumptive Certainty” status Yes No A Were all samples received in a condition consistent with those described on the chain of custody including proper preservation, lab and field temperatures plus prepared and analyzed within holding times?

QUALIFICATIONS/LIMITATIONS Environmental & Construction Management Services, Inc. (ECMS) professional services have been performed, our findings obtained, and our recommendations prepared in accordance with customary principles and practices in the fields of environmental science and engineering. This warranty is in lieu of all other warranties either expressed or implied. ECMS is not responsible for the independent conclusions, opinions or recommendations made by others based on the records review, site inspection, field exploration, and laboratory test data presented in this report. Factual information regarding on-site business operations, conditions, and historical data provided to ECMS is assumed to be correct and complete. ECMS assumes no responsibility for hidden or latent conditions or misrepresentation by the property owner, its representatives, public information officials or any authority consulted in connection with the compilation of this report. The findings set forth in the attached Site assessment report are strictly limited in time and scope to the date of the evaluation(s). The conclusions presented in the Report are based solely on the services described therein, and not on scientific tasks or procedures beyond the scope of agreed upon services or the time and budgeting restraints imposed by the client. The purpose of this report was to assess the physical characteristics of the subject Site with respect to the presence in the environment of hazardous material or oil. No specific attempt was made to check on the compliance of present or past owners or operators or of the Site with Federal, State or local laws and regulations, environmental, or otherwise. Partial findings of this investigation are based on data provided by others. No warranty is expressed or implied with the usage of such data. Much of the information provided in this report is based upon personal interviews and research of all available documents, records and maps held by the appropriate government and private agencies. This is subject to the limitations of historical documentation, availability and accuracy of pertinent records, and the personal recollection of those persons contacted by ECMS personnel. ECMS is not a professional title insurance firm and makes no guarantee, explicit or implied that the listing, which was reviewed, represented a comprehensive delineation of past Site ownership or tenancy for legal purposes. Observations were made of the Site and of structures on the Site as indicated within the Report. Where access to portions of the Site or to structures on the Site was unavailable or limited, ECMS is unable to render an opinion as to the presence of hazardous material or oil, or to the presence if indirect evidence relating to hazardous material or oil, in that portion of the Site or structure. In addition, ECMS renders no opinion as to the presence of hazardous material or oil, where direct observation of the interior walls, floor, or ceiling of a structure on a Site was obstructed by objects or coverings on or over these surfaces. The initial site investigation took into account the natural and man-made features of the Site, including any unusual or suspect phenomenon. These factors combined with the Site's geology, hydrology, topography, and past and present land uses served as a basis for choosing a methodology and location for subsurface exploration as well as ground water and subsurface sampling, if done. The subsurface data, if provided, is meant as a representative overview of the Site. 275-gallon Capacity Fuel Oil UST Closure Report 497 Route 28 – Yarmouth, Massachusetts ECMS Project No. 1076.462 Environmental & Construction Management Services, Inc. The conclusions and recommendations contained in this report may be based in part upon various types of chemical data and are contingent upon their validity. As indicated within the Report, some of these data are preliminary "screening" level data, and should be confirmed with quantitative analyses if more specific information is necessary. It should be noted that variations in the types and concentrations of contaminants and variations in their flow paths may occur due to seasonal water table fluctuations, past disposal practices, the passage of time, and other factors. Should additional data or variations of current data become available in the future, these data should be reviewed, and the conclusions and recommendations presented herein modified accordingly. Chemical analyses may have been performed for specific parameters during the course of this Site assessment, as described in the text. However, it should be noted that additional chemical constituents not searched for during the current study might be present in soil and/or ground water at the Site.
