Information and data on a industrial user obtained from reports, surveys, wastewater discharge permit applications, industrial wastewater discharge permits, general permits, and monitoring programs, and from the Public Works Superintendent’s inspection and sampling activities, shall be available to the public without restriction, unless the industrial user specifically requests in writing, and is able to demonstrate to the satisfaction of the Public Works Superintendent, that the release of such information would divulge information, processes, or methods of production entitled to protection as trade secrets under applicable state law. Any such request must be asserted at the time of submission of the information or data. When requested and demonstrated by the industrial user furnishing a report that such information should be held confidential, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public, but shall be made available immediately upon request to governmental agencies for uses related to the NPDES program or pretreatment program, and in enforcement proceedings involving the person furnishing the report. Wastewater constituents and characteristics and other effluent data, as defined in 40 C.F.R. § 2.302, shall not be recognized as confidential information and shall be available to the public without restriction.
