WPDES Renewal Hearing for Mule Hide Mfg. Co. - Cornell | WisCommunity


Permittee: Mule Hide Mfg. Company, 50 Bridge St., Cornell, WI, 54732

Facility Where Discharge Occurs: Mule Hide Mfg. Company, 50 Bridge Street

Receiving Water And Location: Chippewa River in the McCann Creek and Fisher River Watershed of the Lower Chippewa River Basin in Chippewa County.

Brief Facility Description and Summary of Proposed Changes: Mule-Hide Manufacturing Co., Inc. (hereafter simply MHM) manufactures approximately 210 tons per day of dry roofing felt and facer. To produce the felt recycled paper and wood chips are refined in a thermo mechanical pulping system which provides the raw material for two paper machines. In facer production fiberglass replaces the wood fiber as the raw material and sizing and carbon black are also added. MHM treats and recycles most of its process wastewaters. In-plant treatment includes pH control, screening and primary clarification.

Sludge from the primary clarifier is either recycled into the finished product or landfilled. Not all wastewaters are recycled, however. Seal water and bearing cooling water from stock pumps, defibrators and chip refiners, water softener (ion exchange) regeneration wastes, sand-filter backwash water, boiler blowdown, and noncontact cooling water are combined and discharged to the catch basin via Outfall 001. Changes to the permit: Outfall 002 and Sample Point 009 have been removed from this permit due to the encapsulation of Outfall 002 so that it can no longer be used. Intake Flow Monitoring has been added to the permit.

A Settleable Solids limit of 0.2 ml/L has been added to the permit as well as Acute WET testing at Outfall 001. Permit Drafter’s Name, Address, Phone and Email: Emma Lorenzen, 101 S. Webster St. PO Box 7921, Madison, WI, 53707-7921, (608) 267-7643, Emma.Lorenzen@wisconsin.gov Basin Engineer’s Name, Address, Phone and Email: Geisa Thielen, 1300 W Clairemont Avenue, Eau Claire, WI 54701, (715 )836-7570, Geisa.Thielen@wisconsin.gov

The Department has tentatively decided that the above specified WPDES permit should be reissued.

Proposed Mercury Variance: The Department has determined that a water quality-based effluent limitation (WQBEL) of 1.3 ng/L for mercury is needed to protect wildlife and human health in the above-named receiving water. The permittee has submitted an application for an alternative mercury effluent limitation (AMEL). The application included a pollutant minimization program (PMP) plan for mercury as required under s. NR 106.145(8), Wis. Adm. Code. The Department concludes that the permittee is eligible for a variance based on the information submitted, information on file and the findings provided in s. NR 106.145(1), Wis. Adm. Code. The Department and the permittee have mutually agreed upon an AMEL of 48 ng/L, expressed as a daily maximum, continued influent and effluent monitoring, and permit language requiring implementation of the PMP. The Department proposes to grant the AMEL, which represents a variance to the water quality standard used to derive the WQBEL, as provided for under s. NR 106.145(6), Wis. Adm. Code. The designated use of the receiving water will not change as a result of the variance. This mercury variance must be approved by USEPA prior to its inclusion in the final reissued permit.

Hearing Date, Time, and Location: October 4th at 2 pm located at 1300 W Clairemont Avenue, Eau Claire, WI 54701

Hearing Officer, Name, Address, City/State/Zip , and Phone: Jason Knutson, 101 S. Webster St. PO Box 7921, Madison, WI, 53707-7921, (608) 267-7894
