. SECTION 3 e PROHIBITIVE DISCHARGES (A) No person shall discharge or cause to be discharged any storm water, ground water, roof runoff, sub-surface drainage, down spouts, yard drains, and ponds or lawn spra~s into any sanitary sewer. Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to a natural outlet approved by the Approving Authority. Unpolluted water may be discharged upon prior written approval of the Approving Authority to a storm sewer or natural outlet, or into the sanitary sewer system by an indirect connection whereby such discharge is cooled, if required, and flows into the sanitary sewer, provided the waste does not contain materials or substances in suspension or solution in violation of the limits prescribed by this article. No person shall ever i~crease 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 pollutant-specific limitations contained in this ordinance or any Federal Categorical Pretreatment Standards. In cases where, and in the opinion of the Approving Authority, the character of the sewage from any manufacturer, or industrial plant building, or other premises is such that it will damage the system or cannot be treated satisfactorily in the system, the Approving Authority shall have the right to require such user to dispose of such waste otherwise and prevent it from entering the system. No person engaged in commercial hauling of waste shall drain, flush, or clean out any tanks containing chemical liquid waste for the purpose of transporting such waste to a site of disposal unless such person possesses a permit from the City or State of Texas to perform such acts or services. Any facility that cleans out any tanks that contains chemical liquid waste shall keep a log of operation that is acceptable to the Approving Authority and made available for inspection by the City at any reasonable time. No waste whatsoever from outside the City shall be hauled into the City for disposal within the City unless written approval is obtained from the Approving Authority. (B) No person shall discharge into the public sewer or cause to be discharged either directly or indirectly any of the following described substances, materials, water or waste: 1. Any liquid having a temperature higher than one hundred fifty (150) degrees Fahrenheit (sixty-five [65] degrees centigrade) or liquid which raises the temperature of the sewage treatment plant's influent to one hundred four (104) degrees Fahrenheit or above. 2. Any water or wastes which contain wax, grease, or oil, plastic or other substance that will solidify or become discernibly viscous at temperatures between thirty-two (32) degrees and one hundred fifty (150) degrees Fahrenheit. 3. Any solids, liquids or gases which by themselves, or by interaction with other substances, may cause fire or explos ion haza rds, 0 f' in any othe I" way be j njuI'ious to persons, property, or the operator of the sewage works. 4. Industrial waste which creates an atmosphere in the sewer measuring greater than ten per cent (101) of the lower explosive limit. Instruments used for the measurement of explosivity shall use units of percent of LEL, shall be calibrated before and after use with standard mixtures, shall be accurate to plus or minus twenty percent (201), shall be serviced at intervals recommended by their manufacturer, and shall be approved by the Approving Authority. q
