Re: Proposed Work Scope and Budget Pre-Remedial Activities Mobil Station No. 2713 Lee, New Hampshire NHDES Site No. 199203034

Dear Ms. Marts:

Weston Solutions, Inc. (WESTON®) is pleased to present the following site-specific work scope and budget (WS&B) for pre-remedial activities at Mobil Station No. 2713 (Lee Mobil) in Lee, New Hampshire (Site). Historical operations at the Site have resulted in the release of gasoline related volatile organic compounds (VOC) to the subsurface. Currently soil, groundwater, and drinking water at and downgradient of the Site have been impacted by these releases and VOCs have been detected at concentrations exceeding applicable New Hampshire Department of Environmental Services (NHDES) standards. This WS&B was prepared for Oyster River Investors, Inc. (subject property owners) at the request of NHDES to conduct the following:

• Evaluate the existing analytical data to identify data gaps, which will require assessment/investigation prior to the commencement of remedial activities.

• Assess current conditions at the Site (physically, chemically, and hydrogeologically) in preparation of future remedial activities.

• Preparation of a site-specific soil excavation/disposal bid specification (Bid Spec) document.

To address each of these items outlined above WESTON proposes conducting the tasks summarized below.

Task 1.1 Background Research, Data Gap Analysis, Site Reconnaissance

Since 1992, numerous investigations have been conducted at the Site, to assess groundwater, soil, and drinking water quality at and in the vicinity of the Site. To develop a complete understanding of current conditions at the Site to assist in the preparation of a site-specific

G:\PROPOSAL\GOVT\201 l\NHDS\Lee Mobc\WorkScope doc Ms. Jennifer Marts N.H. Department of Environmental Services -2- 25 January 2011

Bid Spec document, WESTON will conduct a detailed evaluation of existing site conditions, which will include:

• Document/informationextraction from the NHDES One-Stop Database.

• Review of analytical data to assess potential data gaps, which would require evaluation prior to preparation of the Bid Spec document.

• A Site Reconnaissanceby the WESTONField Technical Leader1NHDESpersonnel to assess current site conditions.

a A review of the current Site ConceptualModel.

Task 1.2 Site Specific Soil Excavation/Disposal Bid Specification Preparation

Based on information gathered during the above evaluation, WESTON will prepare a detailed Site-Specific Soil Excavation/Disposal Bid Spec document using the Bid Spec document template developed by NHDES. This Bid Spec document will be used by the remedial contractor as a basis for costing estimating this remedial action and as a Scope of Work for implementing the remedial action. WESTON will provide a draft copy of the Bid Spec document to NHDES for review prior to fmalizing and submitting to the remedial contractor.

A list of assumptions that apply to the tasks described in this work scope have also been included. If you have any questions regarding this proposed WS&B for the investigative activities at the Site, please do not hesitate to contact me at (603) 656-5453.

Very truly yours,

Subject Site: Lee — Mobil 13052, 48 Concord Road DES Site #19903034, ETHER Project #15968 (Activity# 166688)

Dear Mr. D’Angelo:

In 2003, the Department of Environmental Services (DES) requested that each Oyster River Investors, Inc. (ORI) and ExxonMobil Corporation complete a subsurface investigation in the vicinity of the former underground storage tanks (USTs)/pump island and existing USTs!pump island, respectively. The investigations indicated that elevated concentrations of MtBE and other petroleum volatile organic compounds (VOCs) remain in the soil primarily in the vicinityof the former pump island and USTs, including an area beneath the existing pump island. Based on the data presented in the January 9, 2003 Soil Contamination Report prepared by HTE Northeast, Inc. and the January 26, 2003 Site Investigation Report prepared by Groundwater and Environmental Services, Inc., an estimated 6,000 tons of petroleum impacted soil remain on-site.

Although potable water supply options were assessed by ORI and DES between 2005 and 2010, source area removal is the more favorable and cost effective remedial approach for this site. DES believes that soil excavation will help address the on-site contamination and eventually the off-site water supply contamination. The ability to address both issues provides a significant advantage over the water supply only solutions. DES notes that additional remedial work, such as in-situ chemical oxidant injections, may be required as a final “polishing” step followingthe soil removal activities.

Prior to initiating the remedial work, DES requires the installation of additional soil borings and monitoring wells to better define the nature and extent of soil and groundwater contamination for the development of the bid specifications. Please submit a work scope and budget to complete this work no later than February 24, 2011. DES anticipates the soil boring and monitoring well installation program will be completed during March 2011, and the bid specifications will be submitted by April 30, 2011. Soil excavation activities shall be completed during May/June 2011.

Prior to soil excavation, the pump island and canopy and the “Mobil”sign will need to be removed to access the contaminated soil located beneath the concrete apron and grass island, respectively. The excavation willalso impact the catch basin system; therefore, it is anticipated that the catch basins and associated piping willbe removed to access the impacted soil beneath those areas. Therefore, DES anticipates that the Mobil station will need to shut down for approximately 2 to 3 weeks during this planned remedial action.
