MCA is part of a Zinc Coalition that was formed by IZA in the aftermath of the Washington Department of Ecology rainwater runoff project that was concluded in 2014. Misuse of the information related to zinc from the runoff report is influencing the Governor’s office and the legislative bodies.

Letter-writing advocacy, with guidance from IZA, is showing positive impacts. Several meetings have been scheduled with IZA and Coalition members to discuss the shortcomings in the runoff report and the outdated clean water regulations. MCA members that have facilities in Washington were asked to get involved in the effort. Similar issues are being seen in California, the Great Lakes region and in Canada.
