Executive Summary

Haley & Aldrich, Inc. (Haley & Aldrich) has performed a Phase I Environmental Site Assessment (Phase I) of the Canaan Hydroelectric Station in Canaan, Vermont (herein referred to as the “subject site”). This Phase I was performed for Public Service of New Hampshire (PSNH) doing business as Eversource Energy (Eversource) in support of the potential sale of the property as part of the divestiture of its generating facilities. This Phase I was performed in conformance with the scope and limitations of the ASTM E 1527-13 Standard and All Appropriate Inquiries (AAI) Rule1. Deviations from this Standard, if any, are described in Section 1.4 of this report.

This executive summary provides a bullet list of key findings including recognized environmental conditions (RECs) identified during this Phase I followed by a more detailed summary of the Phase I report.

KEY FINDINGS

 One REC, creosote-impacted soil below the former woodstave penstock, was identified in connection with the subject site. However, the impacted soil has been removed, and regulatory closure related to the remedial action is currently pending.  CRECs were not identified in connection with the subject site.  Haley & Aldrich does not recommend additional assessment.

SUBJECT SITE DESCRIPTION

The Canaan Hydroelectric Station is an approximately six-and-a-half acre site in Canaan, Vermont in the Connecticut River Valley (Figure 1). The subject site is located approximately 520 ft north of Vermont State Route 114/Gale Street on Powerhouse Road. The subject site is located on the Vermont/New Hampshire state border. An Eversource substation located on the subject site was not included in the subject site assessment for the current Phase I.

BACKGROUND

The subject site was included in an uncompleted portfolio of environmental site assessments (ESAs) conducted by Haley & Aldrich in 1998 and 1999 in connection with the anticipated sale of PSNH’s generating facilities at that time. ESAs were discontinued and not finalized when the sale of the facilities was terminated. The previous ESAs included a due diligence assessment and limited investigation of the subject site in 1998 and 1999; however, the work was not done in accordance with the current ASTM standard. Environmental data and findings from the previous work were accessed from Eversource’s and Haley & Aldrich’s internal records for use in the current Phase I. Results of the previous ESA and limited investigation are referenced within Section 3 of this Phase I report.

1 American Society for Testing and Materials (ASTM) E 1527-13 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process as referenced in 40 Code of Federal Regulations (CFR) Part 312 (the All Appropriate Inquiries [AAI] Rule) (“ASTM E 1527-13 Standard”). Specified terms as are used in ASTM E 1527-13 are in italics in this report and defined in the Glossary at the end of the report text.

OBJECTIVE

The objective of a Phase I is to assess whether “recognized environmental conditions” (REC), controlled RECs (CREC), and historical RECs (HREC) are associated with the subject site. Haley & Aldrich’s conclusions are intended to help the user evaluate the “business environmental risk”2 associated with the subject site. Haley & Aldrich’s opinion regarding a REC's potential impact on the subject site is based on the scope of our work, the information obtained during the course of our work, the conditions prevailing at the time our work was performed, the applicable regulatory requirements in effect at the time our work was performed, and on our experience evaluating similar sites.

RECOGNIZED ENVIRONMENTAL CONDITIONS

The ASTM E 1527-13 Standard defines a REC in part as “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.”

The following REC was identified in connection with the subject site.

REC #1: 2009 Creosote-Impacted Soil Excavation and Disposal

Creosote-impacted soils were identified below the former woodstave penstock. A Site Investigation was completed by the Johnson Company in May 2009. A soil management plan was developed for the subject site. Impacted soil was removed and disposed off-site in September 2009, in conjunction with replacement of the penstock. Approximately 1,447 tons of soil were shipped to Casella USA Landfill in Coventry, Vermont in September 2009.

The Vermont Department of Environmental Conservation (VTDEC), a division of the Vermont Agency of Natural Resources (VTANR), closed the spill file on 20 July 2009. Despite remediation of the impacted soils, the hazardous site file remains open on the VTDEC database. Eversource submitted a request to close the file along with documentation regarding soil removal on 29 September 2015 and, at the time of this Phase I, has not yet received a response. Upon achievement of regulatory closure, this REC can be considered an HREC.

CONTROLLED RECOGNIZED ENVIRONMENTAL CONDITIONS

The ASTM E 1527-13 Standard defines a CREC as a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls.

CRECs were not identified in connection with the subject site.

2 Business Environmental Risk defined in ASTM E 1527-13 Standard Practice for Environmental Site Assessments as a risk which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated in this practice. Consideration of business environmental risk issues may involve addressing one or more non-scope considerations.

HISTORICAL RECOGNIZED ENVIRONMENTAL CONDITIONS

The ASTM E 1527-13 Standard defines an HREC as “a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).”

HRECs were not identified in connection with the subject site.

SUMMARY AND RECOMMENDATIONS

In summary, Haley & Aldrich identified one REC during this Phase I consisting of the creosote-impacted soil previously identified below the former woodstave penstock prior to penstock replacement in 2009. The impacted soil has been removed from the subject site and regulatory closure for the remedial action is pending from VTDEC. Therefore, no further actions are recommended relative to the REC.

CRECs and HRECs were not identified in connection with the subject site.

Recommendations are limited to those required by the ASTM standard and do not address regulatory compliance.

The remainder of this report contains additional information regarding the Phase I, the resulting findings summarized above, and limitations affecting this report.

v 1. Introduction

This report presents the results of an ASTM Phase I (Phase I) conducted at the Canaan Hydroelectric Station located at 108 Powerhouse Road in Canaan, Vermont (herein referred to as the “subject site”). The approximately six-and-a-half acre subject site is an active hydroelectric generating facility that is located on the Connecticut River in Canaan, Vermont, as shown on the Project Locus, Figure 1. This Phase I was conducted for Public Service of New Hampshire (PSNH) doing business as (dba) Eversource Energy (Eversource) in support of the potential sale of the property as part of the divestiture of its generating facilities.

1.1 OBJECTIVE

The objective of a Phase I is to assess whether “recognized environmental conditions” (REC), controlled RECs (CREC), and historical RECs (HREC) are associated with the subject site by evaluating site history, interviews, existing observable conditions, current site use, and current and former uses of adjoining properties as well as potential releases at surrounding properties that may impact the subject site. Haley & Aldrich’s conclusions are intended to help the user evaluate the “business environmental risk” associated with the subject site. The “business environmental risk” is defined in American Society for Testing and Materials (ASTM) E 1527-13 Standard Practice for Environmental Site Assessments as a risk which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated in this practice. Consideration of business environmental risk issues may involve addressing one or more non-scope considerations.

RECs are defined in the ASTM E 1527-13 Standard as “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.” The definitions of RECs, CRECs, and HRECs are included in the Glossary section of this report.

1.2 SCOPE OF SERVICES

The Phase I was performed by Haley & Aldrich, Inc. (Haley & Aldrich) and was performed in conformance with the scope and limitations of the ASTM E 1527-13 Standard and All Appropriate Inquiries (AAI) Rule1 and in accordance with Haley & Aldrich’s proposal to Eversource dated 24 July 2015 (“Agreement”) as authorized via Purchase Order 02279342 dated 3 August 2015. The Phase I limitations and Agreement are attached hereto as Appendix A.

As part of this Phase I, Haley & Aldrich conducted visual observations of site conditions and of abutting property use and interviewed a key site manager, who also serves as an applicable tenant representative (site reconnaissance); reviewed federal, state, and tribal environmental database

information, federal and state environmental files, previous reports (if identified and provided), and site historical use records; and formulated conclusions regarding the potential presence and impact of RECs.

1.3 NON-SCOPE CONSIDERATIONS

The ASTM E 1527-13 Standard includes the following list of “additional issues” that are non-scope considerations outside of the scope of the ASTM Phase I practice: asbestos-containing materials, biological agents, radon, lead-based paint, lead in drinking water, wetlands, regulatory compliance, cultural and historic resources, industrial hygiene, health and safety, ecological resources, endangered species, indoor air quality unrelated to releases of hazardous substances or petroleum products into the environment, and mold. These items were not included in this Phase I of the subject site.

A limited assessment of the presence of polychlorinated biphenyls (PCBs) is included in the ASTM work scope. Accordingly, Haley & Aldrich’s assessment of the presence of PCBs is limited to those potential sources specified in the ASTM E 1527-13 Standard as “electrical or hydraulic equipment known or likely to contain PCBs…to the extent visually and or physically observed or identified from the interview or records review.”

Historically, PCBs may have been present in on-site transformers or other electrical equipment. According to Eversource’s Staff Senior Engineer, the fossil stations and hydroelectric stations are essentially “PCB-free” with regards to significant oil storage in transformers, and although facilities may continue to store small volumes of PCB containing oil in equipment on site, a program is in place to eliminate PCB sources as they are encountered in the normal course of business.

1.4 LIMITING CONDITIONS/DEVIATIONS

Haley & Aldrich completed this Phase I in substantial conformance with the ASTM E 1527-13 Standard. With the exception of the deviations listed below, Haley & Aldrich did not make additions to or deviate from the ASTM E 1527-13 Standard to complete this Phase I:

• Limited areas along the riverbank between the penstock and the Connecticut River were not observed due to steep and densely vegetated terrain.

1.5 USER RESPONSIBILITIES

The completion of this Phase I is only one component of the process required to satisfy the AAI Rule. In addition, the user must adhere to a set of user responsibilities as defined by the ASTM E 1527-13 Standard and the AAI Rule. User responsibilities are discussed in Section 6.6 of this report. A user seeking protection from Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) liability as an innocent landowner, bona fide prospective purchaser, or contiguous property owner must complete all components of the AAI process in addition to meeting ongoing obligations. AAI components, CERCLA liability relief, and ongoing obligations are discussed in the AAI Rule and in Appendix XI of the ASTM E 1527-13 Standard.

3. Previous Site Investigations and Related Investigations

Environmental Site Assessment and Limited Site Investigation at Canaan Hydroelectric Station

As part of the earlier due diligence, Haley & Aldrich performed an ESA in September 1998, which was followed by a limited site investigation with targeted sampling in November 1999. At the time, the subject site was owned and operated by PSNH and the hydroelectric station was in operation, consistent with current site use.

The 1998 ESA did not reveal evidence of RECs in connection with the subject site.

Cinder piles, used to seal headgates and tailrace gates during maintenance, were identified during the 1998 ESA. The cinders had been tested for RCRA metals and TCLP organics and determined not to exhibit characteristics of hazardous wastes. This material was not observed during the 2015 site visit.

Targeted soil sampling was conducted in November 1999 to evaluate the substation located on the subject site for potential releases of oil and PCB-containing oil from historical operations. The substation is excluded from the sale of generating facilities and not part of the subject site for the current Phase I. The substation is discussed in Section 5.3.2 as a nearby site.

4. Site History

Haley & Aldrich assessed past usage of the subject site and adjoining properties through a review of:

• Sanborn Fire Insurance Maps dated 1887, 1893, 1904, 1909, 1914 and 1925; • Topographic Maps dated 2012; • Aerial Photographs dated 1984, 1986, 1987,1994, 1999, 2006, 2008, 2009, 2011 and 2012; • Previous Site Assessments and Related Investigations; • Eversource Provided Documents; • Municipal records; and • Interviews with subject site personnel

Copies of pertinent information obtained from historical references reviewed are included in Appendix C. Unless otherwise noted below, per the ASTM standard, sources were reviewed dating back to 1940 or first developed use, whichever is earlier, and at 5-year intervals if the use of the property has changed within the time period. The table below provides date ranges for available historic records reviewed at the subject site.

4.1 SUBJECT SITE

The Canaan Hydroelectric Station was constructed by PSNH and placed into service in 1927. Since 1927, the site has been used as a hydroelectric station. Although the date the subject site was first developed is not known, due to the long historic use of the subject site as a hydroelectric station, the initial date of development of the subject site is not relevant to this Phase I.

The table below provides a detailed summary of pertinent information from the historical sources reviewed:

5.3 DETAILED DESCRIPTION OF RELEVANT INFORMATION

5.3.1 Subject Site

The subject site was listed on the following databases:

• U.S. Environmental Protection Agency (USEPA) Facility Index System as an electric generator; • RCRA CESQG, generating less than 100 kilogram (kg) of hazardous waste, or less than 1 kg of acutely hazardous waste per month. No violations; • Vermont Recovered Government Archive Hazardous Waste Facility; • Emergency Response Notification System (ERNS), for releases listed below; • VTDEC Hazardous Sites List (Site# 20093945, additional information provided below); • VTDEC Stormwater Permit List; and • NHDES ALLSITES, for releases listed below.

Documented spills at the subject site are described below in chronological order:

Database Spill Description Potential Impact Reference 4 Dec. NHDES Approximately 5 to 10 gallons of lubricating No Impact. 1998 199812189 oil was spilled.

An Eversource substation located at the subject site is excluded from the sale and was not included in the subject site assessment. The substation is discussed as a nearby site in Section 5.3.2.

5.3.2 Nearby Sites

Several sites were listed in the database report within the applicable search radii or identified in regulatory records reviews. Due to their location with respect to the subject site (distance from the subject site, location of the site relative to inferred groundwater flow, etc.), or status (closed regulatory file, etc.), several of the sites are not likely to adversely affect the subject site and are not discussed herein. Only those sites adjacent to the subject site and sites with a potential to have impacted the subject site are discussed below. The complete database report and relevant records review information is included in Appendix D.

Note: Although, the addresses are correct, some nearby sites were mapped incorrectly in the database report. The actual distance to the subject site is listed below.

 On-Site Substation:

Haley & Aldrich conducted a limited site investigation with targeted sampling in November 1999 to evaluate the substation located on the subject site for potential releases of oil and PCB- containing oil from historical operations. VOCs were not detected above laboratory reporting limits in groundwater. PCBs were not detected above laboratory reporting limits in soil samples. Total petroleum hydrocarbon (TPH) was detected at concentrations lower than the VTANR soil screening value of 1,000 parts per million (ppm) in two soil samples. Data tables are provided in Appendix B.

 Canaan Main Post Office, 350 Christian Hill, Canaan, VT:

The Canaan Main Post Office is located apparently hydrologically upgradient, approximately 200 feet north/northwest of and adjacent to the subject site. The site is listed on the UST, leaking UST (LUST), RGA LUST, and RGA HWS databases.

A 500 gallon No. 2 fuel oil UST was removed from the Post Office facility in 1995. Impacts to soil, as indicated by photoionization detector (PID) readings, were observed in the excavation to remove the UST. Composite soil samples from the excavation were analyzed for TPH. No groundwater was observed in the excavation. Excavated soils were returned to the excavation pending soil sample analytical results.

A limited site investigation, involving 11 test borings to bedrock refusal, was conducted on 2 May 1996. Soil sample results did not exceed VTANR Soil Screening Values (SSV) for either residential or industrial sites. Groundwater was not encountered in the borings. VTDEC assigned the site a Site Management Activity Completed (SMAC) designation on 26 June 1996, indicating that the release achieved regulatory closure.

Based on VTDEC’s SMAC determination and the absence of groundwater in the overburden at this location, this adjacent site does not have the potential to impact the subject site.

5.4 VAPOR MIGRATION

The ASTM 1527-13 standard states that "for the purposes of this practice, “migrate” and “migration” refers to the movement of hazardous substances or petroleum products in any form, including, for example, solid and liquid at the surface or subsurface, and vapor in the subsurface". Thus, this section specifies whether or not Haley & Aldrich perceives a risk of vapor migration to the subject site.

To assess a vapor migration risk Haley & Aldrich conducted a detailed review and analysis of the site- specific environmental database report and/or other reasonably ascertainable records to assess whether:

1. Off-site properties have documented volatile organic compounds (VOC) contamination located within 100 feet of the subject property, or

2. Off-site properties have documented volatile petroleum hydrocarbon contamination within 30 feet of the subject property. Based on Haley & Aldrich’s records review, it is unlikely that a potential source of vapor migration currently exists beneath the site.

6. Site Reconnaissance and Key Personnel Interview

A site visit to observe subject site conditions was conducted by Joanna Sebik of Haley & Aldrich on 17 August 2015. Access to the subject site was provided by Eversource’s Staff Environmental Engineer.

Haley & Aldrich personnel observed accessible interior areas of the subject site buildings, including the gatehouse and access points to the dam. Haley & Aldrich also observed the exterior portions of the subject site, including the property boundaries, and observed adjoining property conditions from the subject site boundaries and/or public thoroughfares. No weather-related conditions that would limit Haley & Aldrich’s ability to observe the subject site or adjoining properties occurred during the site visit.

An interview with Eversource’s Hydro Environmental Safety & Training Coordinator, the key site manager, was performed in conjunction with the site visit.

Per the ASTM Standard, past owners, operators, and occupants of the subject site who are likely to have material information regarding the potential for contamination at the subject property shall be contacted to the extent that they can be identified and that the information likely to be obtained is not duplicative of information already obtained from other sources. Because of the long historical ownership history of the property by PSNH, dating to approximately 1927, identification and contacting of past owners, operators and occupants of the subject site is impracticable and not considered a data gap for this Phase I.

The findings of the subject site visit and interviews are discussed below. Site photographs are included in Appendix E.

ASTM E 1527-13 Standard Section 10.8 requires that, prior to the site visit, the current subject site owner or key site manager and user, if different from the current owner or key site manager, be asked if there are any helpful documents that can be made available for review. Provided information is listed below and relevant information from these documents has been incorporated into this report.

6.1 CURRENT USE OF THE PROPERTY

An active Eversource hydroelectric power generation station is in operation at the subject site. An ALTA survey is currently in progress and will be added to Appendix F when available.

A substation, operated by Eversource, is also located at the subject site, between the powerhouse and office/storage building, but was not included in the subject site assessment. The substation is discussed as a nearby site in Section 5.3.2.

6.2 GENERAL DESCRIPTION OF STRUCTURES

Four buildings are present at the subject site.

• The powerhouse is a brick and masonry building, which houses the water driven generator and operational controls. • The compressor room is a wood frame building, located adjacent to the surge tanks, which houses a compressor to bubble air through the surge tanks to prevent icing and a restroom. • The gatehouse is a wood frame building, which houses the head gate mechanism at the dam and the hydraulic trash rake at the entrance to the penstock. • The office/storage building is a wood frame building located near the gatehouse, which houses a small office and miscellaneous supplies, such as shovels, spill kits, and a flammables cabinet.

Other structures located on-site include the following:

• The 1360 foot long steel penstock runs parallel to Powerhouse Road from the Canaan Dam south to the surge tanks. The penstock was installed in September 2009 to replace a previously existing woodstave penstock. Approximately 540 feet of the penstock is located above ground, with the northern and southern portions (totaling 820 feet) being buried. • A small park with picnic tables is located at the southern portion of the subject site, on top of a buried portion of the penstock. • Two approximately 30,000 gallon steel surge tanks are located on a concrete pad at the end of the penstock. • The Canaan Dam is a 300 foot long, 20 foot tall concrete gravity dam spanning the Connecticut River. The dam retains an approximately 20-acre pond. River outflow matches inflow to the pond.

6.3 USE, STORAGE, AND DISPOSAL OF PETROLEUM PRODUCTS AND HAZARDOUS MATERIALS

Petroleum products and/or hazardous materials were observed or reported to be used, stored, and/or disposed of at the subject site as described below. Unless otherwise noted, no leaks, stains, floor drains or other evidence of potential releases to the subsurface were observed.

The compressor is known to contain small amounts of oil. Sorbent pads were observed on the floor around the compressor.

A flammable materials storage cabinet located in the powerhouse contained small volumes of aerosols, adhesives, and lubricants. Sorbent pads were observed on the floor around the turbine in the powerhouse.

A flammable materials storage cabinet located in the office/storage building contained small volumes of gasoline, propane, lubricants, and motor oil. A partially full 16 gallon waste oil drum and hydraulic oil are also stored in the office/storage building.

A 16 gallon waste oil drum was also observed in the gatehouse, as was ice melt contained in 5 gallon buckets.

6.4 OTHER SUBJECT SITE OBSERVATIONS

The table below summarizes items that were observed and/or reported at the subject site during the site visit other than those items related to use, storage, and disposal of petroleum or hazardous materials (described in Section 6.3 above). If items were observed or reported, they are further described either in the table or below.

6.5 ADJOINING PROPERTY OBSERVATIONS

Haley & Aldrich observed adjoining property conditions from the subject site boundaries and/or public thoroughfares. Conditions observed did not appear to have the potential to adversely impact the subject site.

6.6 USER RESPONSIBILITIES

The AAI Rule requires that the User of the report consider the following:

• whether the user has specialized knowledge about previous ownership or uses of the subject site that may be material to identifying RECs;

• whether the user has determined that the subject site’s Title contains environmental liens or other information related to the environmental condition of the property, including engineering and institutional controls and Activity and Use Limitations (AULs), as defined by ASTM;

• whether the user is aware of commonly known or reasonably ascertainable information about the subject site including whether or not the presence of contamination is likely on the subject site and to what degree it can be detected; and

• whether the user has prior knowledge that the price of the subject site has been reduced for environmentally related reasons.

While such information is not required to be provided to the environmental professional(s), the information can assist the environmental professional in identifying recognized environmental conditions. The “All Appropriate Inquiries” Final Rule (40 CFR Part 312) requires that these tasks be performed by or on behalf of a party seeking to qualify for an LLP to CERCLA liability.

Haley & Aldrich was not provided with a completed questionnaire; however, the absence of such information is not anticipated to affect Haley & Aldrich’s conclusions.

7. Findings and Opinions

7.1 DATA GAPS

Haley & Aldrich’s ability to identify and evaluate RECs at the subject site is conditioned upon data gaps identified as part of this Phase I.

No significant data gaps were identified during the performance of this Phase I.

One minor data gap was identified:

 Limited areas along the riverbank between the penstock and the Connecticut River were not observed due to steep and densely vegetated terrain. This data gap is not likely to adversely impact the conclusions of this report.

Thus, it is Haley & Aldrich’s opinion that sufficient information was obtained to identify subject site conditions indicative of releases or threatened releases of hazardous substances and petroleum hydrocarbons. Haley & Aldrich’s opinion is limited by the conditions prevailing at the time the work is performed and the applicable regulatory requirements in effect.

7.2 RECOGNIZED ENVIRONMENTAL CONDITIONS

The ASTM E 1527-13 Standard defines a REC in part as “the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, ground water, or surface water of the property.”

Haley & Aldrich’s opinion regarding a REC's potential impact on the subject site is based on the scope of the work, the information obtained during the course of the work, the conditions prevailing at the time the work was performed, the applicable regulatory requirements in effect at the time the work was performed, and on Haley & Aldrich’s experience evaluating similar sites.

The following REC was identified in connection with the subject site.

REC #1: 2009 Creosote-Impacted Soil Excavation and Disposal

VTDEC, a division of VTANR, closed the spill file on 20 July 2009. Despite remediation of the impacted soils, the hazardous site file remains open on the VTDEC database. Eversource submitted a request to close the file along with documentation regarding soil removal on 29 September 2015. Eversource submitted a draft Notice to Land Record regarding the cleanup to VTDEC on 3 November 2015 and at

the time of this Phase I, has not yet received a response. Upon achievement of regulatory closure, this REC can be considered an HREC.

7.3 CONTROLLED RECOGNIZED ENVIRONMENTAL CONDITIONS

CRECs were not identified in connection with the subject site.

7.4 HISTORICAL RECOGNIZED ENVIRONMENTAL CONDITIONS

HRECs were not identified in connection with the subject site.

7.5 DE MINIMIS CONDITIONS

The ASTM E 1527-13 Standard defines de minimis conditions as those conditions which “do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.” The ASTM E 1527-13 Standard notes that “conditions determined to be de minimis are not recognized environmental conditions.”

The de minimis condition listed below was identified in connection with the subject site.

De Minimis #1: Historic Small Volume Spills

The interview with the present key site manager and review of regulatory records indicated that minor spills have occasionally occurred at the subject site. These spills have generally been small volumes of lubricating oil and non-PCB hydraulic oil. VTDEC requires that all spills be reported. These spills are contained by Eversource staff and impacted materials (i.e., absorbent booms, pads, etc.), if any, are disposed off-site. These historic spills have generally been confined to the hydroelectric station facilities and have not impacted the Connecticut River. Therefore, the minor releases are considered de minimis for this Phase I.

8. Conclusions

Haley & Aldrich has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of the ASTM Practice E 1527 for the subject site, Canaan Hydroelectric Station in Canaan, Vermont. Exceptions to or deletions from this practice, if any, are described in Section 1.4 of this report.

This assessment has revealed evidence of one REC in connection with the subject site consisting of previously identified creosote-impacted soil below the former woodstave penstock. Regulatory closure related to the soil removal and off-site disposal is currently pending.

CRECs were not identified in connection with the subject site.

Based on the results of this Phase I and anticipated regulatory closure, no additional assessment of the subject site is recommended.

11. Glossary and Other Descriptions

11.1 GLOSSARY

All Appropriate Inquiry (AAI) — that inquiry constituting “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined in CERCLA, 42 U.S.C §9601(35)(B), that will qualify a party to a commercial real estate transaction for one of threshold criteria for satisfying the LLPs to CERCLA liability (42 U.S.C §9601(35)(A) & (B), §9607(b)(3), §9607(q); and §9607(r)), assuming compliance with other elements of the defense.

Business Environmental Risk — a risk which can have a material environmental or environmentally- driven impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated in this practice. Consideration of business environmental risk issues may involve addressing one or more non-scope considerations.

Controlled Recognized Environmental Condition (CREC) – a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).

Data Gap — a lack of or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information. Data gaps may result from incompleteness in any of the activities required by this practice, including, but not limited to site reconnaissance (for example, an inability to conduct the site visit), and interviews (for example, an inability to interview the key site manager, regulatory officials, etc.).

De Minimis Conditions — conditions which do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimis conditions are not recognized environmental conditions nor controlled recognized environmental conditions.

Environmental Professional — a person meeting the education, training, and experience requirements as set forth in 40 CFR §312.10(b).

Historical Recognized Environmental Condition (HREC) — a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).

Key Site Manager — the person identified by the owner or operator of a property as having good knowledge of the uses and physical characteristics of the property.

Material Threat —a physically observable or obvious threat which is reasonably likely to lead to a release that, in the opinion of the environmental professional, is threatening and might result in impact to public health or the environment. An example might include an aboveground storage tank system that contains a hazardous substance and which shows evidence of damage. The damage would represent a material threat if it is deemed serious enough that it may cause or contribute to tank integrity failure with a release of contents to the environment.

Orphan Site — (not ASTM E 1527-13 definition) — sites that could not be mapped due to poor or inadequate address information.

Recognized Environmental Condition (REC) — the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions.

11.2 DESCRIPTIONS OF DATABASES SEARCHED

Numerous regulatory databases were searched during this Phase I. Each database reviewed is described in the database report presented in Appendix D. Those databases required by the ASTM E 1527-13 Standard are identified below.

1. NPL Sites: The National Priorities List (NPL) is a list of contaminated sites that are considered the highest priority for cleanup by the U.S. Environmental Protection Agency (USEPA).

2. Delisted NPL Sites: The Delisted National Priorities List (NPL) is a list of formal NPL sites formerly considered the highest priority for cleanup by the USEPA that met the criteria of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) for deletion from the NPL because a no further response was appropriate.

3. CERCLIS Sites: The Comprehensive Environmental Response, Compensation, and Liability Act Information System (CERCLIS) list identifies sites which are suspected to have contamination and require additional investigation to assess whether they should be considered for inclusion on the NPL.

4. CERCLIS-NFRAP Sites: CERCLIS-NFRAP status indicates that a site was once on the CERCLIS List but has No Further Response Actions Planned (NFRAP). Sites on the CERCLIS-NFRAP List were removed from the CERCLIS List in February 1995 because, after an initial investigation was performed, no contamination was found, contamination was removed quickly, or the contamination was not significant enough to warrant NPL status.

5. Federal ERNS: The Federal Emergency Response Notification System (ERNS) list tracks information on reported releases of oil and hazardous materials.

6. RCRA non-CORRACTS TSD facilities: The Resource Conservation and Recovery Act (RCRA) non- CORRACTS TSD Facilities List tracks facilities which treat, store, or dispose of hazardous waste and are not associated with corrective action activity.

7. RCRA CORRACTS TSD facilities: The RCRA CORRACTS TSD Facilities list catalogues facilities that treat, store, or dispose of hazardous waste and have been associated with corrective action activity.

8. RCRA Generators: The RCRA Generator list is maintained by the USEPA to track facilities that generate hazardous waste.

Subject: Proposal for ASTM Phase I Environmental Site Assessments Eversource Energy Electric Generating Stations New Hampshire

Dear Ms. Cole and Mr. Palmer:

Haley & Aldrich, Inc. (Haley & Aldrich), is pleased to submit this proposal to conduct Phase I Environmental Site Assessments (ESAs) in support of the of the potential sale of up to 14 electrical generating stations current operated by Eversource Energy (Eversource). We have prepared this proposal based on Eversource’s 9 July 2015 Request for Proposal (RFP) and our experience conducting previous ESAs at each of the 14 facilities, including assessment of related properties associated with the generating facilities.

Haley & Aldrich is particularly well qualified to conduct the ESAs. In addition to our previous Phase I ESAs at each of the 14 facilities referenced in the RFP, we also performed Phase II Investigations at some of the sites. Our project team will be led by Amy Dykstra, P.E., our Project Manager, who performed the previous ESAs and is familiar with many of the facilities. Our existing environmental records and reports compiled for the facilities will be used as the basis for review of historical environmental conditions and for conducting the proposed Phase I ESAs in a timely and cost‐efficient manner. We can use our existing data to identify targeted field work to obtain data to supplement the Phase I ESAs if desired by Eversource. Because of our substantial existing knowledge base, our proposed schedule allows for collection of supplemental data within the Phase I timeline established by Eversource.

1 Project Understanding and Experience

Project Understanding

In its Request for Proposals (RFP) dated 9 July 2015, Eversource Energy (Eversource) indicated that it intends to engage an environmental consultant to complete Phase I environmental site assessments (ESAs) for New Hampshire generating facilities in accordance with the ASTM E 1527‐13 (Section 3.2.32) standard. ESAs will include assessments at additional properties related to several of the generating facilities, such as Merrimack Station, Newington Station, Ayers Island hydroelectric station, and the Smith hydro station. A total of 14 ESA reports will be prepared. Based on the RFP, draft ESA reports are due to be submitted to Eversource by 10 October 2015; however, we understand that Eversource may revise the draft submittal date to 12 October 2015, with final ESA reports due by 30 October 2015. Experience

Site‐Specific Experience

Between September 1998 and February 1999, Haley & Aldrich completed Phase I ESAs for 16 electric generating facilities in New Hampshire, which were operated by Public Service of New Hampshire (PSNH), predecessor to Eversource. Based on conditions identified in the Phase I ESAs, supplemental Phase II investigations consisting of test pits, soil sampling, monitoring well installation and/or groundwater sampling were completed at 15 of the 16 facilities during the period through 2002. Draft reports were prepared summarizing the Phase II findings in 1999/2002 for internal use by PSNH.

In general, the results of our Phase I/II ESAs indicated conditions generally consistent with the commercial/industrial uses of the properties as electric generating facilities. No significant releases of oil or hazardous materials (OHM) to the environment or environmental conditions requiring remediation were identified. As described in the scope of services below, the results of the previous ESAs will be used to identify targeted field work that Eversource may wish to conduct concurrently with the Phase I ESAs.

As noted in subsequent sections of this proposal, our Project Manager, Amy Dykstra, performed the field work and prepared reports for our previous Phase I/II work at the generating facilities.

Recent ESA and Utility Company Services

Haley & Aldrich completed approximately 70 Phase I ESAs during the past year and has completed an average of approximately 50 ESAs per year over the past five years.

We have been conducting work for the utility industry since Haley & Aldrich was founded in 1957. One of our earliest projects involved geotechnical services for PSNH for design of the Merrimack Station cooling pond during the late 1950s. Our Environmental Professionals have been working on PSNH/Eversource projects since the early 1980s. Table I contains a matrix illustrating Haley & Aldrich’s experience in providing environmental services to Eversource and its predecessor companies in New Hampshire, including our previous due diligence work at electrical generating facilities and work at other sites.

As Haley & Aldrich has grown to a nation‐wide company, our services have expended to assist utility companies located throughout the country, principally in the Northeast, Midwest, Southeast and West

 American Electric Power  NiSource, Inc  Central Hudson Gas & Electric  Northeast Utilities  Central Maine Power  Northern Illinois Hydropower  Connecticut Light & Power  NSTAR Electric & Gas Corporation  Duke Energy  PG&E  Iberdrola USA  PPL Generation LLC  National Grid  Vermont Electric Power Company

Proposal for: Eversource Energy Page | 2 Haley & Aldrich 2 Project Team and Qualifications

Haley & Aldrich’s Project Team for the Eversource ESA project includes Environmental Professionals with up to 32 years of experience in environmental projects in the State of New Hampshire. The following staff have been committed to the project.

 Amy Dykstra, P.E., Project Manager: Amy conducted our previous Phase I/II work at the generating facilities and, therefore, is very familiar with operations and site conditions at many of the 14 facilities. She is a New Hampshire Professional Engineer with more than 17 years of experience in environmental due diligence assessment, site investigation, remediation and permitting, with particular focus on services to our utility clients. Amy’s experience with Eversource and its predecessor companies includes: the Phase I/II ESAs for 16 PSNH generating sites and related investigations conducted during 1998 to 2002; assessment/treatment/disposal of dredged cooling pond sediments, soil management and groundwater monitoring/well decommissioning for the Merrimack Station Clean Air Project (CAP) during 2008 to 2012; investigation, remediation and monitoring in connection with redevelopment of the former Manchester Steam Plant with the PSNH Energy Park headquarters; and assessment/remediation/monitoring at several Area Work Centers (AWCs), electrical substations, transformer locations, former manufactured gas plants (MGPs) and other sites, such as ash landfills. Amy’s most recent work with Eversource includes remediation of soil at the Berlin electrical substation, investigation of potential residual impacts from historic releases of petroleum and PCBs at the Hooksett AWC, investigation of a transformer oil release at the Amherst Substation and soil management during recent utility construction at Energy Park.

As Project Manager for the Eversource generating station ESAs, Amy would be Haley & Aldrich’s principal point of contact with Eversource and responsible for technical execution, coordination/scheduling and financial management of the project.

 Robert Mullin, P.E., Senior Reviewer: Bob is a New Hampshire PE with more than 32 years of experience in environmental assessment, remediation and permitting. His experience with Eversource and its predecessor companies includes: technical reviewer for the PSNH generating facility ESAs during 1998 to 2002; Project Manager/Senior Reviewer for our work for the Merrimack Station CAP; project management and engineering for our work on due diligence assessments, site investigations, risk assessments and remediation at numerous AWCs, electrical substations, and former MGPs and other environmental legacy sites.

As Senior Reviewer, Bob would be responsible for overall quality control on the generating station ESAs and the regulatory interpretations presented in our reports and available for consultation with Eversource as needed during the project.

 William Haswell, P.E., Senior Technical Consultant: Bill is a New Hampshire PE with more than 25 years of experience, including extensive experience in assessment of environmental conditions and evaluation of potential environmental liabilities for our utility clients and in remedial design and implementation at sites impacted by coal ash, MGP residuals and other contaminants.

As Senior Technical Consultant for the Eversource generating facility ESAs, Bill would be responsible for review and evaluation of potential environmental liabilities identified during Phase I/II ESAs and available for consultation with Eversource as needed during the project.

Proposal for: Eversource Energy Page | 3 Haley & Aldrich 2

 Abigail Cohan, Technical Lead – Environmental Site Assessments: Abby has more than 10 years of experience focusing on environmental due diligence assessments, site investigation and regulatory compliance. She is Haley & Aldrich’s technical lead for ESAs conducted in the northeast. Abby will be responsible for internal coordination of the Eversource generating facility ESAs within Haley & Aldrich and for verifying that our ESA reports conform to ASTM guidelines, regulatory standards and Eversource’s internal guidelines, if any, for ESAs.

Figure 1 is a proposed organization chart for the Eversource project. Staff currently designated for on‐ site work for the Phase I ESAs and potential supplemental investigations include engineers, geologists and scientists with two to ten years’ experience, with our most experienced staff designated for the three fossil fuel power stations.

Richard Van Etten will be Haley & Aldrich’s Risk Assessor for the project. Richard has more than 25 years of experience in the environmental field, including Phase I/II ESAs. His most recent focus has been on human health risk assessment. If desired by Eversource, Richard will assess the potential risk to human health based on existing chemical data and supplemental data that may be obtained at the site. The intent of risk characterization work is to either reduce the number of RECs that may be identified during the Phase Is or to provide perspective with respect to RECs in consideration of the commercial/industrial use of the generating facilities.

We will be able to supplement our staff with experienced environmental professionals from our Boston and Portland offices to expedite the project as necessary to meet Eversource’s schedule requirements. We will seek Eversource’s approval of changes to or addition of staff to the Project Team during the course of the work, if needed.

Proposal for: Eversource Energy Page | 4 Haley & Aldrich 3 Scope of Work, Schedule and Safety

Scope of Work and Schedule

ASTM E 1527‐13 Standard Phase I ESA Scope and Proposed Schedule

Haley& Aldrich’s standard Phase I ESA scope of work conforming to the ASTM E 1527‐13, with a summary of user responsibilities is included in Attachment I. Figure 2 contains a proposed schedule for completion of the Phase I ESAs for each generating facility within the deadline contained in the RFP.

Consistent with the RFP, our scope of services includes proposed environmental professional services to complete an ESA and an “All Appropriate Inquiry” (AAI) for each facility. The goal of the Phase I ESA is to assess whether Recognized environmental conditions (“RECs”), as defined in Attachment I, exist at each facility.

A User Responsibility Questionnaire in connection with All Appropriate Inquiries under the ASTM standard (Attachment II) will be provided to Eversource. We request that Eversource provide the information in the questionnaire to us for each property under assessment. Please refer to Attachment I for information regarding the responsibilities of users seeking protection from the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) under the AAI rule.

Our scope of services will include the following:

1. Records Review: We will review our records from our previous ESAs for each of the facilities, readily available records provided by Eversource, and readily ascertainable State and Federal environmental records (i.e., records available from the New Hampshire Department of Environmental Services (NHDES) “OneStop” database and from a commercial environmental database search service) to help identify RECs at each facility. The database search will include State and Federal environmental records including those listed in the RFP and historical records in conformance with the ASTM E 1527‐13 Phase I standard.

The records review will be conducted in consultation with you at the start of the project to determine whether Eversource wishes to proceed with site‐specific “targeted work” described below in addition to the Phase I services.

2. Site Reconnaissance: A Haley & Aldrich Environmental Professional will visit each facility, and each related property, to obtain information regarding the potential likelihood of RECs at each location. The periphery of each of the subject and adjoining properties and structures and a representative sample of the interior of on‐site structures commonly accessible will be observed during the site reconnaissance.

As shown on the schedule (Figure 2), we plan for concurrent site visits by our team of Environmental Professionals at specific facilities and at facilities within various regions of the state in order to complete site reconnaissance in a timely, cost‐ effective manner. Time required for visits is estimated based on the complexity of the facility and our previous assessment of site conditions. If desired by Eversource, additional targeted work (e.g., limited field work such as sampling of existing monitoring wells, if present) may be conducted in conjunction with site reconnaissance at particular facilities.

Proposal for: Eversource Energy Page | 5 Haley & Aldrich 3

3. Interviews: Haley & Aldrich will interview current Eversource “key site managers” for the facilities, Eversource’s NH Generation Environmental Staff and individuals, if available, who have knowledge of past operations and uses of the properties. Interviews will be conducted concurrently with the site reconnaissance.

We will also interview available local officials, such as the fire department, board of health and building department. Interviews with State officials, such as NHDES, would be coordinated with Eversource’s NH Generation Environmental Staff.

4. Evaluation and Draft/Final Report: A draft report meeting ASTM requirements and prepared to at least 75% completion will be submitted for review by Eversource. A separate report will be prepared for each of the 14 generating facilities. Following review and revision, as necessary, two paper copies and one electronic version of our final report will be submitted to Eversource.

Our proposed schedule (Figure 2) is designed to submit draft reports for Eversource review on a staggered schedule during the course of the work. Dates for draft report submittal occur between 25 August and 25 September 2015, with each final report submitted on or before 10 October 2015. Our proposed schedule includes float time that may be consumed with completing selected field work and final reporting before 26 October 2015.

5. Meetings, Communications and Project Management: Our scope of services includes the following:

 Attendance at a Project Award and Kickoff Meeting anticipated on either 27 or 28 July 2015, including discussion of existing data and potential targeted field work in conjunction with Phase I site reconnaissance (estimated four hours);  Written updates to Eversource Environmental Staff submitted via electronic mail on a biweekly basis during the course of the work from 27 July through completion (assumed seven update reports through 30 October 2015), including progress summaries for all phases of work, data collected, and preliminary findings (magnitude, extent, and regulatory implications) regarding potential RECs identified during the course of our work as well as a budget status;  Immediate verbal notification will be provided regarding health and safety incidents and newly discovered environmental conditions; and  A meeting or conference call to discuss each draft report upon submittal and review by Eversource (estimated one hour per meeting/conference call).

Potential Additional Site‐Specific Targeted Work

As noted above, the results of our Phase II assessment work during the period from 1999 to 2002 indicated soil and groundwater conditions generally consistent with the commercial/industrial uses of the generating facilities and related properties.

Existing data will be reviewed to identify additional targeted field work that could be conducted concurrently with the Phase I site reconnaissance if desired by Eversource. Based on our understanding of site conditions existing at the time of our previous assessments, the field work would be intended to establish whether conditions at the site continue to indicate the absence of releases of OHM that would

Proposal for: Eversource Energy Page | 6 Haley & Aldrich 3

constitute RECs or require remediation. Characterization of risk to human health using the existing data, with supplemental data obtained as necessary, could be used to establish whether a condition of No Significant Risk with respect to potential exposure to soil exists for continued industrial/commercial uses of the facilities. As noted above, the intent of risk characterization would be to either reduce the number of RECs identified during the Phase I ESAs or to provide perspective relative to the limited level or absence of risk to human health with identified RECs given the existing uses of the properties.

Our proposed schedule (Figure 2) includes allowances for time for field work and associated laboratory testing of samples that may be obtained, if the field work is performed. Our estimated fees (Section 4) do not include field work or laboratory testing. Upon authorization of the project, we would be prepared to meet with Eversource (i.e., at the project kickoff meeting) to develop specific scopes and budgets for targeted field work desired by Eversource.

Safety and Site Access

Safety Practices

Haley & Aldrich has developed a strong culture of safety. We integrate health and safety into all aspects of our work, including work in accordance with Eversource’s safety program, to comply with all OSHA requirements. Site‐specific Health and Safety Plans will be prepared in accordance with the OSHA Hazardous Waste Operations and Emergency Response (HAZWOPER) standard (29 CFR 1910.120) for any for supplemental investigations involving soil and groundwater sampling.

Site Access

Haley & Aldrich will work closely with the Eversource NH Environmental Staff and Eversource’s designated project liaisons. We will endeavor to refine and optimize our proposed project schedule to access each site for reconnaissance in an expeditious and cost‐effective manner within the working hours (Monday through Friday, 7 AM through 5 PM) established by Eversource.

Proposal for: Eversource Energy Page | 7 Haley & Aldrich 4 Hourly Rates, Terms & Conditions and Estimated Fee

Rates and Projected Hours

Haley & Aldrich’s hourly rates for the project are included in Attachment IV. We have projected the level of effort for completion of each Phase I ESA based on our experience at each facility, our existing data regarding conditions at each site, and the varying sizes and complexity of the facilities. As noted above, we have grouped facilities by geographic location and level of complexity in order to establish our schedule and to reduce travel costs and other expenses.

Terms and Conditions/Confidentiality

Haley & Aldrich’s services will be provided in accordance with the Northeast Utilities Service Company and Haley & Aldrich, Inc. General Terms and Conditions, Consulting Services, Revision 4 dated 16 May 2013 and mutually signed on 6 February 2014, which is included in Attachment V.

Haley & Aldrich’s work will be conducted in accordance with Eversource’s Supplier Code of Conduct and Property Impact and Incidental Property Damage Procedure, as appropriate.

We understand that the ESA project will be conducted under a mutually agreed upon confidentiality agreement.

Our ESAs will be subject to the limitations included in Attachment III. As noted in the limitations, we would be pleased to work with Eversource in authorizing third party reliance on the ESAs using the procedures described in the attachment.

Assumptions

We have prepared this proposal based on the following assumptions:

 Eversource Generation will assist with coordination of site visits, key staff interviews and be available for conference calls and draft report reviews as needed.  Interviews with key site managers will be conducted concurrently with site reconnaissance. Additional time and expenses will be incurred if multiple site visits are required.  One commercial environmental database search will be sufficient for each generation facility including contiguous related adjacent properties. Our fee includes a total of 17 commercial database searches.  Estimated costs listed below include time and materials to complete Phase I ESAs only. If additional targeted investigations are requested by Eversource, the investigations will be completed for an additional fee charged on a time and materials basis using the project‐specific rate schedule included in Attachment IV.  Non‐scope considerations or identification of de minimis conditions will not be included in our Phase I ESAs unless requested by Eversource.

ASTM E 1527‐13 Phase I Environmental Site Assessment Standard SCOPE OF SERVICES & User Responsibilities

Scope of Services

The scope of services below summarizes Haley & Aldrich’s proposed environmental professional services required to complete an environmental site assessment and ”All Appropriate Inquiry” for a parcel of commercial real estate with respect to the range of contaminants within the scope of Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) (42 U.S.C. §9601), in accordance with 40 CFR Part 312.20 (“All Appropriate Inquiries”), to permit a user to satisfy one of the requirements to qualify for CERCLA’s innocent landowner defense, contiguous property owner liability protection, or bona fide prospective purchaser liability protection ("landowner liability protections" or "LLPs"), establishing that the user did not know of or had no reason to know that any hazardous substance was disposed on, in, or at the subject property.

Title 40, Part 312.11 of the Code of Federal Regulations provides that the procedures of ASTM International Standard E 1527‐13 entitled “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process” (“ASTM E 1527‐13”) may be used to comply with the requirements of 40 CFR 312, “All Appropriate Inquiry”.

The goal of ASTM E 1527‐13 is to assess whether recognized environmental conditions (“RECs”) exist at the site. REC means the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. Accordingly, the five core components of Haley & Aldrich’s standard scope of services, performed in accordance with ASTM E 1527‐13, shall include:

Records Review – In accordance with ASTM E 1527‐13, Haley & Aldrich will obtain and review reasonably ascertainable records that will help identify RECs in connection with the property.

Site Reconnaissance ‐ Haley & Aldrich will visit the subject property to obtain information indicating the likelihood of identifying RECs in connection with the property. On the visit to the property, Haley & Aldrich will visually observe and document the property and the periphery of any structure(s) located on the property to the extent our view of the same is not obstructed. Additionally, Haley & Aldrich shall visually observe and document accessible components of the interior of any building located on the property. Conditions of adjoining properties will also be observed and documented from the subject property boundaries and/or public thoroughfares.

Interviews with Owners and Occupants ‐ ASTM E 1527‐13 requires that interviews be performed with a “key site manager” (a person with good knowledge of uses and physical characteristics of the property), as well as, past and present owners, operators, and occupants of the property to obtain information indicating RECs in connection with the property. Please provide contact information for the “key site manager” so Haley & Aldrich can arrange a mutually convenient appointment to interview the key site manager. We also ask that you advise all known past and present owners, operators, and occupants of

I‐1 of 3 our site visit so we may interview a number of them as required by ASTM E 1527‐13. Last, in accordance with standard ASTM E 1527‐13, we request that you arrange to have assembled and available to Haley & Aldrich, on the day of our property visit, or as soon as possible, copies of any previous environmental documents (User provided information), including: environmental site assessment reports, environmental compliance audit reports, environmental permits, registrations for underground and above‐ground storage tanks, registrations for injection systems, material data safety sheets, community right‐to‐know plan, safety plans, spill prevention plans, emergency preparedness plans, hydrogeologic reports for the property, any government notices concerning the property, hazardous waste records and reports, geotechnical studies, risk assessments, recorded activity and use limitations (AULs),environmental land use restrictions (ELURs), or environmental liens.

Interviews with State and/or Local Government Officials – Haley & Aldrich shall reasonably attempt to interview applicable state and/or local government officials to obtain information indicating RECs in connection with the property.

Evaluation and Report ‐ Haley & Aldrich will interpret the information and data assembled from work scope items No. 1 through No. 4 above, and will formulate conclusions regarding evidence of RECs at the subject property and their potential impact on the subject property. We will prepare a report in accordance with the format set forth in ASTM E 1527‐13, unless otherwise directed. The report will generally include a summary, introduction, site description, records, site and interview documentation, supporting documents, findings, conclusions, recommendations, and appropriate professional statements as required by ASTM E 1527‐13.

User Responsibilities

A user seeking protection from Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) liability as an innocent landowner, bona fide prospective purchaser, or contiguous property owner must complete all components of the AAI process in addition to meeting ongoing obligations. AAI components, CERCLA liability relief, and ongoing obligations are discussed in the AAI Rule and in Appendix XI of the ASTM E 1527‐13 Standard.

The AAI Rule requires that the user of the report consider the following:

 Whether the user has specialized knowledge about previous ownership or uses of the subject site that may be material to identifying RECs;

 whether the user has determined that the subject site’s Title contains environmental liens or other information related to the environmental condition of the property, including engineering and institutional controls and Activity and Use Limitations (AULs), as defined by ASTM;

 whether the user is aware of commonly known or reasonably ascertainable information about the subject site including whether or not the presence of contamination is likely on the subject site and to what degree it can be detected; and

 whether the user has prior knowledge that the price of the subject site has been reduced for environmentally related reasons.

We request that you provide this information to us. A copy of the User Responsibility Questionnaire is included in Attachment II. Though it is not required by the AAI Rule or the ASTM E 1527‐13 Standard

I‐2 of 3 that this information be provided to Haley & Aldrich, failure on the part of the user to obtain such information for their own records, should it be reasonably ascertainable, may invalidate the user’s compliance with the AAI Rule for CERCLA liability protection in the future.

Attachment II User Responsibilities Questionnaire Attachment II

USER RESPONSIBILITIES QUESTIONNAIRE All Appropriate Inquires under ASTM E1527‐13

Date: Project: Address: Prepared By:

In order to qualify for one of the Landowner Liability Protections offered by the Small Business Liability Relief and Brownfields Revitalization Act of 2001 (the “Brownfields Amendments”), the user must conduct “All Appropriate Inquiry (AAI),” which includes consideration of the following information (if available). Though it is not required that this information be provided to the environmental professional for the completion of the ASTM E1527‐13 Phase I Site Assessment, failure of the user to consider this information could result in a determination that “All Appropriate Inquiry” is not complete.

(1.) Environmental cleanup liens that ared file or recorded against the site (40 CPA 31225). Are you aware of any environmental cleanup laws against the property that are filed or recorded under federal, tribal, state or local law? If yes, give a description and attach copies of the liens.

(2.) Activity and land use limitations that are in place on the site or that have been filed or recorded in a registry (40 CFR 312.26). Are you aware of any AULs, such as engineering controls, land use restrictions or institutional controls that are in place at the site or have been filed or recorded in a registry under federal, tribal, slate or local law?

(3.) Specialized knowledge or experience of the person seeking to qualify for the LLP (40 CER 312.28). As the user of this ESA do you have any specialized knowledge or experience related to the property or nearby properties? For example, are you involved in the same line of business as the current or former occupants of the property or an adjoining property so that you would have specialized knowledge of the chemicals and processes used by this type of business?

(4.) Relationship of the purchase price to the fair market value of the property if it were not contaminated (40 CFR 312.29). Does the purchase price being paid for this property reasonably reflect the market value of the property? If you conclude that there is a difference, have you considered whether the lower purchase price is because contamination is known or believed to be present at the property?

II‐1 of 2 (5.) Commonly known or reasonably ascertainable information about the property (40 CFR312.30). Are you aware of commonly known, or reasonably ascertainable information about the property that would help the environmental professional to identify conditions indicative of releases or threatened releases? For example, as user,

(a.) Do you know the past uses of the property?

(b.) Do you know the specific chemicals that are present or once were present at the property?

(c.) Do you know of spills or other chemical releases that have taken place at the property?

(d.) Do you know of any environmental cleanups that have taken place at the property?

(6.) The degree of obviousness of the presence of likely presence of contamination at the property, and the ability to detect the contamination by appropriate investigation (40 CFR 312.311). As the user of this ESA, based on your knowledge and experience related to the property are there any obvious indicators that point to the presence or likely presence of contamination at the property?

EDR’s GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in forming an opinion about the impact of potential contaminant migration.

Assessment of the impact of contaminant migration generally has two principal investigative components:

1. Groundwater flow direction, and 2. Groundwater flow velocity.

Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

TC04370171.2r Page A-1 GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW DIRECTION INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers).

TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

HYDROLOGIC INFORMATION Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

Refer to the Physical Setting Source Map following this summary for hydrologic information (major waterways and bodies of water).

HYDROGEOLOGIC INFORMATION Hydrogeologic information obtained by installation of wells on a specific site can often be an indicator of groundwater flow direction in the immediate area. Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

AQUIFLOW® Search Radius: 1.000 Mile.

EDR has developed the AQUIFLOW Information System to provide data on the general direction of groundwater flow at specific points. EDR has reviewed reports submitted by environmental professionals to regulatory authorities at select sites and has extracted the date of the report, groundwater flow direction as determined hydrogeologically, and the depth to water table.

TC04370171.2r Page A-3 GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW VELOCITY INFORMATION Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils.

GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.
