November 28, 2018 Ms. Susan Bull Oil Control Program Maryland Department of the Environment 1800 Washington Blvd, Suite 620 Baltimore, Maryland 212 RE: SECOND SEMI-ANNUAL 2018 MONITORING REPORT MDE Case No. 2006-0442-HA High s Store No. 1 4101 Norrisville Road, Jarrettsville, Harford County, Maryland Facility ID No. 2057 Dear Ms. Bull: Groundwater & Environmental Services, Inc. (GES), on behalf of High s of Baltimore, LLC (High s), is pleased to submit the attached Second Semi-Annual 2018 Monitoring Report for the above mentioned facility. For the Second Semi-Annual 2018 monitoring period, the following activities were completed: gauging of site monitoring wells MW-1, MW-2 and MW-3 was completed on October 25, 2018 (tank field observation pipes were gauged as dry this day); semi-annual gauging and sampling of site couplet monitoring wells MW-4/4D, MW-5/5D and MW-6/6D were completed on October 25, 2018; quarterly sampling of the liquid granular activated carbon (LGAC) filtration system at 3914 Madonna Road was completed on August 28, 2018 (Third Quarter 2018). The homeowner did not respond to GES attempts to coordinate sampling during the October 25, 2018 sampling event and therefore, has not been sampled for the Fourth Quarter at the time of this report. GES will make an additional attempt to reach the homeowner before the end of the year. Results of the quarterly LGAC sampling will be provided to the MDE in separate correspondence, once the sampling event at 3914 Madonna Road. can be coordinated and completed; quarterly sampling of the LGAC filtration system at 3921 Greenpeak Road was completed on July 31 and October 24, 2018 and; quarterly sampling of the residential potable well at 3922 Greenpeak Road was completed on July 31 and October 24, 2018. On December 8, 2016, GES submitted the Second Semi-Annual 2016 Monitoring and Conceptual Site Model Report for the case. Based on the analysis presented in the Conceptual Site Model (CSM), GES concluded that impacts of methyl tert-butyl ether (MTBE) currently identified in select potable wells within the community of Charbonnet/Madonna, as associated to MDE Case No.2006-0442-HA, are most likely sourced from historical petroleum releases originating from the Maryland Department of Natural Resources (DNR) Madonna Ranger station property located at 3919 Madonna Road. During June 2017, the MDE, in conjunction with the Harford County Health Department (HCHD), 1350 Blair Drive, Suite A, Odenton, MD 21113 1-800-220-3606 www.gesonline.com

Ms. Susan Bull OCP Case#2006-0442-HA November 28, 2018 Page 2 of 2 conducted additional potable water sampling in the community of Charbonnet/Madonna. GES was provided the analytical results from the investigation, and has incorporated the data into the Historical Potable Well Analytical Data Summary attached to this correspondence as Table 2. On December 13 2017, the MDE issued correspondence to High s which included a directive to work in cooperation with the DNR to initiate routine sampling at several additional potable well locations in the community of Charbonnet/Madonna. GES was informed by our client that attempts were made to contact DNR who was unresponsive to the attempted communication. In April 2018, High s was provided a February 28, 2018 DNR report indicating the DNR s position that the former LUST cases associated to the DNR Madonna Ranger Station (located at 3919 Madonna Rd.), were not the source of historical potable well impacts determined within the community of Charbonnet/Madonna. At High s request, GES reviewed the DNR report and concluded that the report was deficient in its presentation of a CSM explaining the distribution of MTBE within the community as sourced exclusively from the High s site. Therefore, due to DNR s failure to communicate with High s, and their position that they are not a Responsible Party, High s cannot in good faith proceed with the expanded sampling requested from MDE. High s is not in agreement with the MDE s December 13, 2017 directive for additional potable sampling. However, in order to protect and serve the citizens of the local community, an obligation DNR has decided to disregard, Highs has elected, to continue sampling the potable locations (and frequency) noted in the prior MDE directive for LUST # 2006-0442-HA issued to High s on May 16, 2017. If you have any questions or would like additional information, please contact the undersigned at (800) 220-3606, extension 3726 or Herb Meade at (410) 261-5450.

For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas. ppb parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an as-received basis. Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, and ISO 17025) unless otherwise noted under the individual analysis. Measurement uncertainty values, as applicable, are available upon request. Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our staff. This report shall not be reproduced except in full, without the written approval of the laboratory. Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as analyze immediately are not performed within 15 minutes.

The lower result is reported. P^ Concentration difference between the primary and confirmation column > 40%. The higher result is reported. U Analyte was not detected at the value indicated V Concentration difference between the primary and confirmation column >100%. The reporting limit is raised due to this disparity and evident interference. W The dissolved oxygen uptake for the unseeded blank is greater than 0.20 mg/l.
