Macor to Lead WLSSD Regulatory Affairs and Laboratory


DULUTH, MN – Western Lake Superior Sanitary District (WLSSD) Executive Director Marianne Bohren, has named Julie Macor as WLSSD Director of Environmental Services. In this new role, Macor oversees WLSSD’s compliance with various environmental permits, WLSSD’s industrial pretreatment program and its certified laboratory. She is responsible for developing, implementing and enforcing guidelines that promote compliance with the regulations and permits.

“Julie’s high-level technical knowledge, skills and abilities make her a perfect fit for this role. We are fortunate to have internal talent and expertise to fill this important position,” said Bohren. Dr. Joseph Mayasich, retiring at the end of 2020, has served in this role since 2005.

Macor joined WLSSD in 1994 as Chemist to operate specialized equipment for determination of trace metals in wastewater and to oversee adherence to certified lab standards. In 2015, she was promoted to Laboratory Lead where she provided technical leadership and oversaw the daily operation of WLSSD’s certified laboratory to ensure permit compliance, optimum plant operation, and fair distribution of treatment costs to customers.  Julie also managed WLSSD’s pretreatment program for industrial customers and businesses to ensure protection of the treatment plant, conveyance system, and, ultimately, Lake Superior.

Macor earned a Bachelor of Science degree from the University of Minnesota, Duluth with a Major in Biology and a Minor in Chemistry.  Macor has served on Laboratory Certification Rules Steering Committees for both Minnesota Department of Health and Minnesota Pollution Control Agency. Prior to hire at WLSSD, she worked as a Project Manager for a certified independent laboratory specializing in wastewater, drinking water, lake water, and solid waste testing.

Western Lake Superior Sanitary District provides award-winning wastewater and solid waste services to residents, businesses and industries within its 530 square mile legislative boundaries in Southern St. Louis and northern Carlton counties, and is a nationally recognized leader in pollution prevention.
