Jaffrey’s zoning board has decided to hold a site walk before deliberating on a variance request from MilliporeSigma. 

The request, which was discussed by the board during a Tuesday public hearing, asks for a variance from the town’s 100-foot property line setback requirement, which will aid in the construction of a new onsite wastewater treatment plant.

Millipore Engineering Manager John Dishong said during the meeting that the variance would allow his company to clear approximately 1,300 square-feet of trees for an improved stormwater treatment system and utility piping, as well as selectively clearing about 900 square-feet of deciduous trees to install at least a dozen evergreen trees. 

“Our goal here is when we leave [the site], it will provide more buffer than is here today, said Dishong. “We wanted to come here saying we did everything we could... to absolutely minimize touching any zoning issues at all.”

The zoning board scheduled to meet at the project site at 5 p.m. on Thursday. 

MilliporeSigma met with the town’s planning board last month for preliminary discussions about the proposed treatment plant, which includes an 800,000 gallon anaerobic treatment system. A MilliporeSigma representative told the Ledger-Transcript that the treatment plant needs to be operational by 2020 due to “new, town-issued industrial discharge permit limits.”

The new treatment plant will pretreat wastewater onsite before it heads off to the town’s treatment plant, according to Lauren Swett of Woodard and Curran, the company handling the design build process for the project. 

“[Most of the water will] go through this level of pretreatment that will clean the water… you can pretty much drink it,” said Swett, who said the goal is to start construction in the summer or fall. 

Swett said there is already a stormwater treatment system on site, but it needs to be rebuilt. The utility piping is needed to connect the new plant to a biomass plant already on site. 

As a part of the project, Millipore wanted to improve the buffer between the site of the project an a neighboring project on Eastwood Drive. 

A public hearing for the project’s site plan is currently on the planning board’s agenda for June 12. The meeting starts at 6 p.m.
