Mayor Walsh has asked the Federal Energy Regulatory Commission to reconsider its decision to allow construction of a large natural-gas pipeline down Washington and Grove Streets and a metering station across from the West Roxbury quarry to connect it to National Grid's system.

Two residents of the Centre/Grove Street area stood vigil tonight in front of the site where Spectra Energy wants to terminate a large natural-gas pipeline with a "metering and regulating" transfer station for National Grid - across the street from the quarry where they worry ongoing blasting could cause a disaster with the pipeline or transfer station.

Residents plan vigils every Monday at 6:30 p.m.

Residents already inured to explosions at the West Roxbury quarry gathered tonight to get scared even more by the high-pressure natural-gas line planned for Grove and Centre streets along one side of the quarry - and the proposed transfer station across the street from it that would feed the out-of-state gas into National Grid's Boston-area distribution system.

Boston Police report that two people died in an 11:05 a.m. collision between a City of Boston snowplow and a private car at Grove and Centre streets.

The driver of the car, a 65-year-old woman, was pronounced dead at the scene. Her passenger, a 25-year-old woman, was rushed to Brigham and Women's Hospital, where she died.

The facts and circumstances of this accident are currently under investigation by the Boston Police Accident Reconstruction Team and Boston Police detectives. Preliminary information suggests that the accident was a result of the road and weather conditions at the time. It appears that the Operator of the snow plow pulled over and stopped in an attempt to avoid the collision.

Channel 5 reports the younger woman was pregnant.
