Sec. 3111.

A person doing business within this state who discharges to the waters of the state or to any sewer system wastewater that contains wastes in addition to sanitary sewage shall file an annual report on a form provided by the department. The report described in this section shall set forth the nature of the enterprise, indicating the quantities of materials used in and incidental to its manufacturing processes and including by-products and waste products that appear on a register of critical materials compiled by the department and the estimated annual total number of gallons of wastewater, including, but not limited to, process and cooling water to be discharged to the waters of the state or to any sewer system. The information shall be used by the department only for purposes of water pollution control. The department shall provide proper and adequate facilities and procedures to safeguard the confidentiality of manufacturing proprietary processes, except that confidentiality shall not extend to waste products discharged to the waters of the state. Operations of a business or industry that violate this section may be enjoined by an action commenced by the attorney general in a court of competent jurisdiction. The department shall promulgate rules as it considers necessary to effectuate the administration of this section, including, where necessary to meet special circumstances, reporting more frequently than annually.
