Weld Governor Daniel S.Greenbaum Commissioner Board of Health JUN 0 7 199 120 Main Street North Andover, MA 01845 RE: North Andover Exxon Service Station 141 Sutton Street DEP Site ID # 3-0870 WAIVER APPLICATION NOTIFICATION Dear Local Official: This letter is to inform you that the Department has received an application for "Waiver of Approvals" for the above referenced disposal site. The application was submitted by Exxon Company, U.S.A. . The Massachusetts Contingency Plan (310 CMR, 40.00) establishes procedures for assessing and remediating sites where there has been a release of oil or hazardous materials. The Massachusetts Contingency Plan requires that six specific reports be submitted to the Department during the response action process. The Department must approve each of the reports before the next phase of work can be conducted (310 CMR 40.536) . The Massachusetts Contingency Plan also allows those conducting response actions at non-priority sites to apply to the Department for a waiver of required approvals (310 CMR 40.537) . When such a waiver is granted, remedial response actions must still meet all of the other requirements of M.G.L. c. 21E and The Massachusetts Contingency Plan, including submittal of documents to the Department. However, no Department approvals of reports, plans, or other documents will be required as long as the waiver remains in effect. A waiver of approvals will expedite the performance of a remedial response action. At this time, the Department is focusing its limited resources on the disposal sites which present the greatest and most immediate threats to public health • _ One Winter Street Boston,Massachusetts 02108 • FAX(617)556-1049 • Telephone(617)292 5500 Page 2 of 2 BOH Letter and to the environment. These are generally sites classified as priority, based on specific criteria in the Massachusetts Contingency Plan. At non-priority sites, contamination does not threaten public health or the environment, but may at some time in the future if no action is taken. A waiver of approvals allows assessment and cleanup of non-priority sites which otherwise would have to wait until the Department has staff available to oversee response actions. The DEP expects to complete its review of this waiver application and all other relevant information within �6:Odays of receipt of the application in the regional office. The waiver application and any other information submitted to the department may be reviewed by appointment. To make an appointment, please contact the assigned DEP staff person at the phone number listed in the closing of this correspondence. In deciding whether to grant a waiver of approvals for this site, The Department welcomes any additional information that you may wish to be considered for this case. Please submit any information and comments to the Waiver Unit of the DEP regional Office listed above. Information must be submitted on or by thirty days from the date of this letter so that we may include it in our review of this application. The Department will notify you as to the decision made on this waiver application. For specific information regarding this particular waiver E application, please refer all inquiries to either Ida Babroudi or Tom Depersio of the Northeast Regional Office, (617) 935-2160.

If you are a potentially .responsible party as described in Section 5 (a) of MGil ch. 21E, the Massachusetts Oil and Hazardous Material Release Prevention and Response Act, you are also responsible for ensuring that appropriate assessment and remedial action, if necessary, occurs at this property. These and other r.esponsibi.a.i_ti.es/liabilities are described in MGL ch. 21E. Based on a preliminary review, the Department believes that the conditions as described in the report do not constitute an imminent hazard to the pu"b1ic hea-Ith, safety, welfare, or the environment requiring immediate action by the Department. Consequently, further review of the report and/or investigation of the property cannot be given top priority because of the need to attend to cases which appear to pose the most serious threat to public health, safety, welfare, or the environment. Your case will be reviewed in the order in which it was received as staff can be diverted :from top priority cases. In orCler that the Department 's review of your report is as expeditious as possible, you are urged to determine whether the report conforms to the enclosed /au;idelines. Unfortunately, many reports fail to provide sufficient information to fully assess the problem or to allow sound decisions concerning further assessment or .remedial action. Deficiencies often i -2- include a lack of validated data, expert professional interpretation of data or . recommendations for further action. We suggest that you examine your report in light of the general guidelines and policies enclosed to determine whether there are additional steps you should undertake to expand upon your report. Please note that this letter does not: constitute a statement that the referenced property is or is not subject to the provisions of MGL ch. 21E. In addition, be advised that present statutory .requirements compel the Department to maintain and publish a list of locations "to be investigated as possible disposal. sites" of oil or hazardous materials (MGL ch. 21E, section 3A) . Accordingly, based upon information contained in the submitted report, the subject property may be so listed by the Department, and you may be contacted at a future date and be requested to complete a "Preliminary Assessment" and/or "Site Investigation" form. If you have any question about your responsibilities or liabilities under Chapter 21E, you should obtain legal counsel to aelvi.se you. Please direct all further communications on this matter to the letterhead address, and reference the designated DEQE case number. Very truly yours, John J. Fitzgerald, P.E.

RUSSELL SYLVA Commissioner November 20, 1985 Ms. Naomi Trombly c/o Trombly Brothers 4I--Sufton Street z North Andover, MA-01845 RE: NORTH ANDOVER - Citgo Route 125 & Hillside Road Notice of Responsibility Pursuant to M.G.L. Chapter 21E Dear Sir/Madam: The Department of Environmental Quality Engineering is in receipt of an engineering report prepared by IEP, Inc. concerning environmental conditions at the subject site. This report is dated June 1985 and is entitled "21-E M Site Assessment, North Andover Citgo, Route 125 and Hillside Road, North Andover, Massachusetts". Such an assessment has been voluntarily conducted to determine the possible presence of oil or hazardous materials that could potentially constitute a basis for regulatory action by the Department under the provisions of M.G.L. Chapter 21E. . According to IEP, Inc. , the site has been operated:.ae a .service station since 1953, although gasoline pumps and underground storage tanks have probably existed on the site since the mid 1930's. Six underground storage tanks were removed from the site by Zecco, Inc. on April 10, 1985. One 550 gallon tank containing heating oil and one 550 gallon waste oil ,tank were . excavated from along the west side of the building. Four 5,000 gallon steel gasoline tanks were removed from northeast of the building, one of which contained holes. The other four tanks reportedly had surf icial rusting, but were otherwise sound. The investigation conducted by IEP, Inc. was of a limited scope and included: the observation of underground storage tank excavation, installation of four groundwater monitoring wells, screening of soil samples with an HNu photoionization detector, and the analysis of groundwater samples for Volatile Organic Compounds (VOCs) by EPA Method 624. Results of groundwater analyses reveal the presence of four Volatile Organic Compounds including benzene, xylene, toluene and ethylbenzene in monitoring well OW-1 at a total concentration of 4150 ug/l. These compounds are components of gasoline. G1 Trombley Brothers Page 2 Statement of Conclusions/Statutory Liabilities Based upon the aforementioned investigation, a condition of soil and groundwater contamination by Volatile Organic Compounds (VOCs) has been documented at the subject site. Be advised that such conditions constitute a "release" of oil/hazardous materials at the site. The prevention and/or mitigation of such a release or threat of release is governed by Massachusetts General Law, Chapter 21E, the "Massachusetts Oil and Hazardous Material Release, Prevention and Response Act". Chapter 21E identifies as responsible parties the current owner or operator of a site at which there has been a release or threat of release of oil or a hazardous material; the. past owner or operator of such a site; any person who directly or indirectly arranged for the transport, disposal, storage or treat- ment of hazardous materials to or at such a site; and any person who caused or is legally responsible for a release or a threat of release at such a site. Such parties are liable without regard to fault; the nature of this liability is joint and .several. This letter is to inform you in writing that: (1) The Department has determined that a release of oil/hazardous material has occurred at the subject site. Y (2) Additional investigation and assessment is needed to adequately define the impact of this release on public .health. and the environment, and to determine what, if any, remedial/clean up measure is necessary. (3) Information available to the Department indicates that you, as owner of the subject site, are a liabile and "responsible" party pursuant to Section 5(a) of Chapter 21E. (4) Should you fail to implement those acitons deemed necessary by this ' Office., the Department may, pursuant to M.G.L. Chapter 21E, take or arrange for any and all necessary actions at the site. If public 's funds are expended under such conditions, Chapter 21E, Section 11 stipulates that the Attorney General of the Commonwealth of Massachusetts may initiate legal action against the responsible party to recover all costs incurred by the Department in the assessment, containment, .and removal of any release or threat of release of oil or hazardous materials. (5) The liability .of responsible parties in (4) above includes up to three times the cost of: a) all response costs incurred by the Department 'due to the release/ threat of release, including all contract, administrative, and personnel costs; and , I iy1 i S 1 1 i r I Trombley Brothers Page 3 b) all damages for any injury to, destruction, or loss of, natural resources due to the release/threat of release. This liability constitutes a debt to the Commonwealth. The debt, together with interest, would constitute a lien on all your property in the Commonwealth. In addition to the foreclosure remedy provided by the lien, the Attorney General of the Commonwealth may recover that debt or any part of it in an action against you. You may also be liable for additional penalties or damages pursuant to other statutes or common law. Requisite Site Actions The extent of investigation conducted at the site, as reported in the IEP, Inc. report is deemed to be deficient in the following respects: 1) The process of determining groundwater flow'direction was not reported. 2) If the groundwater flow has been accurately determined to flow north/ northeast, no monitoring wells have been installed downgradient of the source of the release, i.e. , the underground storage tanks. 3) Access to the building was not attained, preventing the inspection of internal sumps and floor drains. 4) Reportedly, three underground storage tanks existed on the site prior to 1959; one 500 gallon capacity and two 1000 gallon tanks. In 1959 the 500 gallon tank was replaced by a 4000 gallon tank. The disposition of these tanks has not been determined. In light of the above, the following additional actions are necessary to adequately define and evaluate site conditions and provide sufficient data to theDepartment to determine what, if any, remedial actions are warranted at the site: 1) Groundwater elevations must be accurately measured relative to a common datum and a groundwater contour map must be constructed. 2) A monitoring well must be installed downgradient of the former leaking underground storage tank with subsequent groundwater sampling and analysis to evaluate groundwater quality. 3) Determine the disposition of all underground storage tanks historically permitted to occupy the site. 4) An internal inspection of the building should be executed to determine the existence and status of sumps and floor drains. A written response indicating your intentions to comply with the provisions of this letter is requested within 14 days.

Please forward one copy of this report along with the original signature copy of the enclosed transmittal form BWSC-106 to the attention of Ms. Patricia Donahue at Department of Environmental Protection (DEP),Northeast Regional Office, 205 Lowell Street, Wilmington, MA 01887. Upon receipt of a copy of the transmittal to DEP,GSC will forward copies of this RAM Plan to the Chief Municipal Officer and Board of Health Department of North Andover in accordance with the requirements of 310 CMR 40.1403(3)(d). Subject Property Description The subject property is situated on the southern side of Sutton Street in a commercial/residential area of North Andover, Massachusetts. The subject property is currently owned and occupied by Trombley Brothers, Inc. (Trombley), and is presently an automobile repair facility complete with four service bays, one 10,000-gallon gasoline underground storage tank(UST), one gasoline pump dispenser island, one 1,000 gallon used oil UST,one 1,000-gallon kerosene UST,and one 500-gallon heating oil UST. Please refer to Figures 1 and 2 (Attachment A) for a depiction of the subject site and surrounding area. Background/Regulatory Status In September, 1987, six Exxon-owned USTs were removed from the subject property. These six USTs had been utilized on-site in the storage of gasoline, kerosene, and used oil. During the UST removal activities, a light, non-aqueous phase liquid(NAPL)was observed on the surface of groundwater within the UST excavations. As the result of these UST excavation activities, approximately 150 cubic yards of impacted soil was removed from the UST excavation area and transported to an off-site facility for recycling/disposal. The DEP subsequently listed the subject site as a Location to Be Investigated on October 15, 1988 (WSC/SA#3-0870) in response to the detection of petroleum-related compounds in collected soil and groundwater samples, and the presence of NAPL in the UST excavations. 15 Bonazzoli Ave. • Hudson, MA 01 749 • (978) 568-8740 • (978) 568-9316 Recycled Paper I A Waiver of Regulatory Approvals(Waiver)was subsequently issued to Exxon for the continuation of response actions at the subject site,effective September 22, 1993. Response actions completed at the subject site to-date include soil excavation,NAPL recovery, well installation,and periodic groundwater monitoring. A Tier II Classification Extension Submittal dated July 16, 1998 has been submitted to the DEP for the completion of response actions after the expiration date of the Waiver. Recent Assessment Activities Site-related monitoring wells were gauged with an electronic interface probe(EIP)on May 27, 1998 (refer to Figure 2-Attachment A for well locations). Monitoring well gauging data are presented in Table 1 (Attachment B). NAPL was detected in monitoring wells B-2, MW-10, and MW-11 at thicknesses ranging from 0.03 feet in MW-10 to 0.10 feet in MW-11. Based on the May 27, 1998 gauging data,a groundwater contour map was prepared and is shown as Figure 3 (Attachment A). The groundwater contour map indicates that groundwater flow is in a northerly direction, exhibiting a hydraulic gradient of approximately 0.051 between monitoring wells MW-1 and MW-8. The presence of NAPL in monitoring wells B-2, MW-10, and MW-11 is considered to be a previously existing condition;therefore,no new Release Tracking Number(RTN)has been issued to these detections. Table 2 (Attachment B)displays the historical groundwater sample analytical results from the site-related monitoring wells. As noted in Table 2, samples collected from B-1 and MW4 exhibited concentrations of the targeted analytes in excess of the applicable MCP Method 1 Groundwater Standards. Figure 3 (Attachment A)also depicts the analytical results of groundwater samples collected from site- related wells on May 27, 1998. Release Abatement Measure Activities The RAM activities proposed herein to address the presence of NAPL consist of periodic gauging of selected site-related monitoring wells (at minimum wells B-2, MW-10, and MW-11)with an EIP, and the recovery of detected NAPL with disposable bailers and/or sorbent/passive skimmers. The proposed gauging and bailing events will take place every two weeks for a period of approximately 2/Z months. This schedule may be varied based on conditions observed during the gauging events. The proposed RAM activities will be conducted under the DEP-issued Waiver, while additional monitoring and assessment activities continue concurrently with this RAM as part of the pending Phase II investigation for the subject site. Management of Remediation Waste Recovered NAPL and disposable sorbent skimmers and/or bailers will be stored on-site within appropriate secondary containment until disposal. The proposed RAM activities will commence approximately one week following the submittal of the RAM Plan to the DEP and the appropriate public notification pursuant to 310 CMR 40.1403. Should the proposed scope of work change significantly prior to or following implementation, Exxon will submit a RAM Plan Addendum specifically outlining modifications to the workscope. Scope of Release Abatement Measure Activities If site conditions become significantly different from those previously documented or if an Imminent Hazard or two or 72 hour notification condition exists,all work being performed in conjunction with the RAM will be temporarily suspended until the DEP is notified and approval to continue is received. A site-specific Health and Safety Plan has been prepared for these activities. Should you have any questions, please contact the undersigned at(978) 568-8740.
