RINGLE, Wis. (WSAU) – A paper mill screening processing facility in Ringle has settled a lawsuit with state regulators for violating air pollution laws.

Fiber Recovery will pay the state $95,000 as part of the settlement approved by Marathon County Judge Patrick Brady.

The company uses landfill gas-fired generators to turn paper mill screenings into paper and wood pellets that are sold as boiler fuel.

According to a complaint, Fiber Recovery violated its air permit by failing to test an emissions stack in a timely manner, exceeding nitrogen oxide limits during one test and failing to test the sulfur content in the screenings.

Fiber Recovery also violated state regulations when it dried a test load of sledge without a research and testing exemption.

The state Justice Department says the company has shown compliance with all permit limits and corrected all sampling and recordkeeping deficiencies since the lawsuit.
