(b) Specific Prohibitions. No user shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:

(1) Any pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, gasoline, benzene, naphtha fuel oil, or other flammable or explosive liquid, solid or gas or waste streams with a closed cup flashpoint of less than one hundred forty degrees F (sixty degrees C) using the test methods specified in 40 C.F.R. 261.21;

(7) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;

(8) Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constituting a hazard to humans or animals, or creating any hazard in the receiving waters of the sewage treatment plant;

(9) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;

(10) Any septic tank sludge or trucked or hauled pollutants, except as authorized by the city manager;

(12) Any water or waste which may contain more than one hundred parts per million (ppm), by weight, of fat, oil or grease;

(13) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant;

No user shall ever increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with a discharge limitation unless expressly authorized by an applicable pretreatment standard or requirement. The city manager may impose mass limitations on users who are using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate.

(Ord. 772 § 5, 2019)
