ARTICLE III. SEWERS Page 12 of 12 <br />(Ord. No. NS-2670, § 2, 11-15-04) <br />Sec. 39-57. Infiltration and inflow into sewer system. <br />All city -owned sewer lines and private onsite sewer lines and laterals should be constructed and <br />maintained to prevent water infiltration into the sewer system. Private on -site sewer lines and public <br />sewer lines shall be used only to convey raw sewage. Rainfall runoff sources (including, but not limited <br />to roof drains, site drains, inlets, uncovered wash area drains, etc.) are prohibited from connecting to <br />any public or private sanitary sewer pipeline. <br />(Ord. No. NS-2670, § 2, 11-15-04) <br />Sec. 39-58. Introduction prohibited. <br />No person shall introduce any of the following into the city's sewer system: <br />A. Pollutants that create a fire or explosion hazard in the sewer collection system or the <br />publicly owned treatment works (POTW), including, but not limited to, waste streams <br />with a closed cup flashpoint of less than 140' Fahrenheit or 60' Centigrade using the <br />test methods specified in 40 CFR 261.21. <br />B. Pollutants that will cause corrosive structural damage to the sewer collection pipes <br />and structures, but in no case discharges with pH lower than 5.0, unless the works in <br />specifically designed to accommodate such discharges. <br />C. Solid or viscous substances in amounts which will cause obstruction to the flow in <br />the sewer collection system or the POTW resulting in interference. <br />D. Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a <br />discharge at a flow rate and/or pollutant concentration which will cause interference with <br />the POTW. <br />E. Heat in amounts, which will inhibit biological activity in the POTW resulting in <br />interference, but in no case heat in such quantities that the temperature at the POTW <br />treatment plant exceeds 40' Centigrade (104' Fahrenheit) unless the approval authority, <br />upon request of the POTW, approves alternate temperature limits. <br />F. Petroleum oil, non -biodegradable cutting oil, or products of mineral oil in amounts <br />that will cause interference or pass through. <br />G. Pollutants which result in the presence of toxic gases, vapors, or fumes within the <br />sewer collection system or the POTW in a quantity that may cause acute worker health <br />and safety problems. <br />H. Any trucked or hauled pollutants. <br />I. Large volume discharges in a short period of time (slug flows) that adversely effect <br />the operational capacity of the sewer. <br />(Ord.
