Two logging contractors working in the area near Hudson Bay, Sask., have been fined a total of $19,600 after pleading guilty to several charges under the Clean Air Act.

Lutz Logging Inc. pleaded guilty to two counts of burning industrial waste and received $14,000 in fines and surcharges.

WE Logging pleaded guilty to a single count of the same offence and received a $5,600 penalty.

The waste included oil filters, plastic product containers, oils, hydraulic hoses and aerosol cans, the Ministry of Environment said in a news release.

The illegal activity happened in the fall of 2014 and the companies were charged about a year later.

The companies recently received their fines in Melfort provincial court.
