Climate Adaption and Mitigation - Planning or Assessment

Selected Strategy(ies)	Explanatory Text
Climate-focused Phase I and Phase II ESAs	Climate-focused Phase 1 ESAs may consider current and on-going climate change impacts and consider future impacts to the site or area. For example, an investigation of the site history can include an investigation of site vulnerabilities based on historical and recent climate patterns and events (e.g., floods and drought). Climate-focused Phase 2 ESAs may include use of renewable energy, incorporating remote sensing capabilities, maximize reuse of existing wells (as appropriate) and/or design wells for future reuse, use of field test kits when possible, use of local laboratories when possible, and use of appropriate sized equipment for the project."
Evaluate Reuse options that are climate conscious	Discussion of observed and forecasted climate change conditions and the associated site-specific risk are part of any reuse considerations. Both current and forecasted climate changes may impact the effectiveness of a remedial alternative."
Identify potential risk factors and infrastructure or utility vulnerabilities	Identify potential risk factors and vulnerabilities resulting directly from the impacts of climate change." Possible risk factors and vulnerabilities may include proximity to the ocean, infrastructure vulnerabilities, property affected by a revised FEMA flood plain map, vulnerability related to changes in frequency and intensity of precipitation events, vulnerability of soil type due to moisture and hydraulic changes, and ground and surface drinking water vulnerabilities."

Property Highlights

EPA oversaw a significant removal action at the site between 2015 and 2018. NHDES funded a Phase I Environmental Site Assessment prior to the City of Claremont's acquisition of the property in February 2019 in order to preserve their status as a bona fide prospective purchaser.

Former Use: The former Synergy site was also known as the Claremont Former Manufactured Gas Plant (MGP). According to consultant reports, the Claremont MGP was built in 1859 to provide illuminating gas for the Monadnock Mills complex. Gas manufacturing operations ceased in the mid to late 1940s and the plant was converted for natural gas storage and distribution.
