In Bellingham, the Charles River now flows more freely

Free Charles 2017-03-17_AllenOrsi-554861-edited.jpg

The recent removal of the Old Mill Dam in Bellingham allows the Charles River to now flow freely between the North Bellingham dam to the West Medway dam. Next summer, a stormwater treatment basin will be constructed to clean polluted runoff from Pearl Street. Plantings will  be added to the banks of the river in the fall after the grass has had a chance to become established. Read more 

Siting Board reopens Exelon Power Plant proceedings on water issues   


Two weeks ago the MA Energy Facilities Siting Board (EFSB) decided to reopen proceedings by Exelon Corp. to construct and operate a 200-megawatt peaking power plant in Medway in response to Exelon’s filing of a notice of project change (NPC). When the EFSB approved the project last November, Exelon was seeking to purchase half of the plant’s cooling water, or about 47,000 gallons per day on an annual average, from the Town of Millis with the rest supplied from an on-site well. Exelon now asserts that all of the project’s water can be provided by its well; in an emergency, water would either be trucked in, or provided by Millis. CRWA intervened in the original EFSB proceeding because of our concern about the impacts to the Charles River, tributaries, and groundwater from the plant’s water demand. We remain deeply concerned about this and will be fully participating in the NPC before the EFSB.

Exelon’s on-site bedrock well is about 250 feet from Hopping Brook. This area of the watershed is already highly impacted by existing water withdrawals. Peak summer water demand by the plant could total as much as 190,000 gallons a day and coincides with the time of year when streamflow is already low.  



Yesterday, President Trump signed an executive order to undo environmental regulations to curb climate change. The order targets the Clean Power Plan which required states to reduce emissions from power plants. 

An article in The Conversation explains that people will stand up for environmental regulations when they believe that they personally gain from the rule.
