The Alberta Energy Regulator has laid charges against Tidewater Midstream and Infrastructure Ltd. for a release of acidic water in west-central Alberta. The regulator says the release occurred in Oct. 2019 at Tidewater’s Ram River sour gas processing plant near Rocky Mountain House. It says the acidic water flowed into a nearby creek. Calgary-based Tidewater has been charged with 10 violations under the Environmental Protection and Enhancement Act, including releasing a substance to the environment that caused or may have caused an adverse effect.
