Have you heard of the tar sands crude oil pipeline proposed for Eastern Montana?

You’re not alone – and that may be by design. Join Montana Helath and Climate on Thursday, Oct. 29 for a webinar with and where we’ll cover what you need to know about the Bridger Pipeline Project, the proposed 647-mile tar sands crude oil pipeline that would cross Montana’s wildlife habitat, conservation lands, and vital drinking water.

This is the next Keystone XL and the project should concern anyone who cares about our waterways, Indigenous communities, endangered species, public health, and the climate.

Be part of the fight to stop it on Oct. 29 at 4:30 pm.

❗This is your chance to speak up and tell the PSC that we need transparency about NorthWestern Energy’s plans for data centers – BEFORE the mega-monopoly merger is approved❗

NorthWestern aims to merge with fellow South Dakota-based Black Hills Energy to become a mega-monopoly – all to serve data center customers while becoming even more out of touch with the needs of Montana ratepayers.

The Montana Public Service Commission (PSC) is going to discuss the merger at their meeting TOMORROW (Tuesday, October 27) at 1:30 PM. PSC staff are recommending approval of the merger, despite a lack of transparency around the plans for data center development.

📢 Show up and demand the PSC reject NorthWestern's merger without data center transparency. There is power in numbers! If possible, please attend the meeting in Helena in-person at 1:30 PM at the PSC's office in Helena: Bollinger Conference Room, 1701 Prospect Avenue.

To attend virtually, you must register by the end of Monday (TODAY) by emailing [email protected].
