Before the agency grants a permit for a solid waste facility, allows a significant alteration of permit conditions or facility operation, or allows the change of a facility permittee, the commissioner must notify the county and town where the facility is located, contiguous counties and towns, and all home rule charter and statutory cities within the contiguous townships. If a local government unit requests a public meeting within 30 days after being notified, the agency must hold at least one public meeting in the area near the facility before granting the permit, allowing the alterations in the permit conditions or facility operation, or allowing the change of the facility permittee.
