Spectra Energy holds an information session today on its plans for a new gas pipeline that would run through Westwood, Dedham and West Roxbury and include a "metering and regulating" facility across Centre and Grove streets from the quarry.
And the Federal Energy Regulatory Commission holds a formal hearing on the proposed 5-mile pipeline on Monday.
The session today begins at 5:30 p.m. at the Elks Club, 1 Morrell St. The FERC hearing starts at 6:30 p.m. on Monday at the Dedham Holiday Inn, 55 Ariadne Rd.
Algonquin says it wants to install the new pipeline at National Grid's request, both to add a new supply of gas to the region to improve gas pressure in the area.
Primary roads utilized for routing include Providence Highway, Washington Street, Grove Street, and Centre Street. The pipeline would also cross Interstate 95/State Route 128.
In its FERC draft environmental filing, Algonquin says the pipeline would be almost entirely under parking lots and roads. It says the new facility near the quarry would prove inoffensive and that it would install "a blowdown silencer" to minimize noise from periodic "blowdown events" of one to five minutes.
In addition to federal approval, the company would need permits from Dedham and Boston to dig up local roads to install the pipe.
