The Minnesota Pollution Control Agency (MPCA) Citizen Board has approved an air permit sought by Northern Metals LLC, Minneapolis, as part of siting an auto shredder, with two amendments.

The amended permit includes the following changes from the draft permit that was brought to the board:

  • The feedstock control plan required by the permit will be amended by Northern Metals and resubmitted to the MPCA for review and approval within 60 days of permit issuance. The amended plan will provide more specifics as to supplier audits, inspections and training requirements for company personnel involved with inspecting incoming scrap deliveries and auditing suppliers to ensure that mercury switches have been removed from auto hulks.
  • The potential increase in particulate limits to 2.25 pounds per hour after three years will be brought to the Citizen Board for the board’s consideration before it can be granted. The draft permit did not include board approval of this provision.

Following the MPCA’s approval, the MPCA’s commissioner signed the amendment. The permit is now effective. The final permit will be made available on the MPCA webpage http://www.pca.state.mn.us/chxr6kq after the MPCA commissioner signs it.

Following the approval, the MPCA announced plans to embark on a new effort to learn more about concentrations of fine particles in the air in North Minneapolis. The project follows up on community concerns about ambient air quality raised during the permitting process for the Northern Metals Recycling facility. As part of that effort, the MPCA will site and operate a new air monitor in the industrialized area on the west side of the Mississippi River. Monitoring is expected to continue for three years beginning as soon as possible in 2013.
