Giordani, Penney Engineering, Inc is hereby providing notification to your offices that over the next six months we shall be conducting field work related to the implementation of our Phase IV Remedy Operation Plan at the former Mansfield Motors hazardous waste site located at 297-301 North Main Street, next to the Fire Station. We shall be periodically inspecting and sampling the monitoring wells located at the vacant property. The monitoring wells are sampled every three months. We may also be applying remedial additives to the monitoring wells and injection wells to enhance the biological remediation at the remaining oil contamination in the deep soil and groundwater. The six injection wells are located along North Main Street. During snow removal activities it appears that the DPW damaged at least one of the stickup - type injection wells. Could the DPW repair and straighten the damaged wells? All the fieldwork shall be conducted at Level D personal protection. If the level of protection is upgraded during the course of the work to Level C or above, we shall orally notify Mr. Leite of the upgrade as soon as possible. In accordance with 310 CMR 40.1403(3)(e), you are also hereby notified of the availability of a report that we have prepared for the site. Every six months we are required to submit a Phase V Status and Remedial Monitoring Report for the site to the Department of Environmental Protection ("the DEP").

Riccio, Interim Town Manager TOWN OF MANSFIELD Six Park Row Mansfield, MA 02048 (508)261-7370 RE: Former Mansfield Motors 297-301 North Main Street, Mansfield DEP RTN: 4-01140 Dear Messrs. Riccio and Leite: Mr. Scott Leite, Health Agent TOWN OF MANSFIELD Six Park Row Mansfield, MA 02048 (508)261-7360 On behalf of Mrs. Elizabeth J. Giordani and in accordance with the public involvement requirements specified in the Massachusetts Contingency Plan, Penney Engineering, Inc is hereby providing notification to your offices of the availability of a combined Phase II Comprehensive Site Assessment Report, Phase III Remedial Action Plan, Phase IV Remedy Implementation Plan and Phase IV Completion Station for her vacant property at 297-301 North Main Street. Her property is located adjacent to the Central Fire Station. On February 13, 1992, the Department of Environmental Protection ("the DEP") issued the first Notice of Responsibility to Mrs. Giordani for the gasoline -contaminated soil and groundwater discovered by the Town at her property. Her property became a hazardous waste site. In April 2003, we excavated and recycled 442 tons of petroleum -contaminated soil from the property. We applied remedial additives to remediate the contamination that extended under North Main Street and could not be removed. We monitored the groundwater on a quarterly basis. The concentrations of the contaminants continued to decrease. In 2007 we were ready to close the site when the results for only one well were found to be higher than we ever detected. We suspected a new release near the well or tampering with the well. We have confirmed that two private water supply wells are located within 500 feet of the site and there is a potential for someone to drink the water from the wells. As a result, the groundwater at the site must meet be remediated to meet the GW-1 cleanup standards. Our most recent groundwater sampling results exceed the GW-1 cleanup standards. We shall continue to monitor the groundwater on a quarterly basis and may apply additional remedial additives. We shall begin to notify both your offices of our sampling in advance. Local officials may obtain copies of the combined Phase II Comprehensive Site Assessment Report, Phase III Remedial Action Plan, Phase IV Remedy Implementation Plan and Phase IV Completion Statement by contacting the DEP 125 High Street, Mansfield, MA 02048 4 (508) 261-1288 ® FAX (508) 261-1208 web: www.PenneyEng.com email: sales@PenneyEng.com Mr. Nicholas J.
