(1) 
Records kept by the city with respect to the nature and frequency of discharges from any user shall be available to the public without restriction unless the user specifically requests, and is able to demonstrate to the satisfaction of the city, that the release of such information would divulge information, processes or methods of production entitled to confidentiality under the law.
(2) 
Users shall clearly mark "confidential" on all areas of reports requested to be held confidential from the public. Upon request for this information, the city shall determine if such information is legally afforded this protection under the law. Only information marked "confidential" which the city determines qualifies as such shall be withheld from the public.
(3) 
Documents claimed as "confidential," however, shall not be withheld from any state or federal agency responsible for oversight of the city's NPDES permit or authority to implement the NPDES, or federal or state pretreatment programs. Wastewater constituents and characteristics and other "effluent data" as defined by 40 CFR 2.302 will not be recognized as confidential information and will be available to the public without restriction.
