Environmental fines for former wastewater plant operators

A former Langdon wastewater plant operator has been fined $17,250 after being sentenced Feb. 10 on three violations of the Environmental Protection and Enhancement Act

Samantha Mantai was found guilty of two counts of knowingly contravening a condition of an approval and one count of attempting to provide false or misleading information. The court found as fact that Mantai had directed other operators to shut off an autosampler and not shake wastewater composite samples. 

In 2016, Clarke Wallace, Mantai’s supervisor at the time, pleaded guilty to one count of contravening the conditions of an approval under the Environmental Protection and Enhancement Act. He was fined $10,000.

In an agreed statement of facts, Wallace admitted to directing operators to turn off an automatic sampling device during a wastewater discharge. This meant a sample from one of the plant’s treatment devices was not included in the daily composite sample, which is a requirement of the plant’s operating approval.

The charges are related to incidents in 2013 at the Langdon wastewater plant east of Calgary.
