RE: September 2024 Chlorine Emission Report Parameterc - US Magnesium, LLC Rowley Facility
Dear Mr. Bird,
Please find attached the September 2024 Monthly Chlorine Emissions Report for the US Magnesium
LLC (US Mag) magnesium plant, located at Rowley, Utah. US Mag submits this report as required by its
Title V Operating Permit Number 4500030003, dated December 12,2018. The report includes the rolling
l2-month total source-wide chlorine emissions (ll.B.l.a.3) and the rolling 60-month scheduled
maintenance emissions (ll.B.l .b.3) submitted with the chlorine emission totals. Per USM's letter dated
September 22,2022, the magnesium production has been temporarily taken offline for necessary repairs.
The decrease in monthly chlorine emissions is due to this.
If you have any questions, please do not hesitate to contact me at [phone].
Sincerely,
//.--;Z-*b-
