(a) Duty to Notify of Substantial Changes. All industrial users shall promptly notify the Director, at least thirty (30) days in advance, of any substantial changes in the volume or character of pollutants in their discharge to the XWWTP, including the listed or characteristic hazardous wastes for which the industrial user has submitted initial notification under 40 CFR 403.12(p).
(b) Prohibition Against Dilution. No industrial user shall increase the use of process water or potable water or in any other way attempt to dilute a discharge as a partial or complete substitution for adequate treatment in an attempt to achieve compliance with a pretreatment standard or requirement.
(c) Notification of Problematic Discharges. All significant industrial users shall notify the XWWTP immediately of all discharges that could cause problems to the XWWTP, including any slug loads.
(d) Bypassing Pretreatment Facility Prohibited.
(1) All industrial users are prohibited from intentionally, recklessly, or negligently bypassing any pretreatment facility.
(2) Pretreatment facilities are required to be operated at all times; however, if an industrial user knows in advance of the need for a bypass due to necessary repairs or maintenance, it must give prior notice to the Director and XWWTP, at least ten (10) days before the date on which the bypass is to occur.
(3) In the case of an unanticipated/unplanned bypass, the industrial user must notify the Director and XWWTP orally within twenty-four (24) hours of becoming aware of the bypass. This twenty-four (24) hour notice must be followed within five (5) days with a written description of the bypass, its cause, duration and what has been done to rectify the situation or, if the bypass has not been corrected, how long it is expected to continue.
