WHEREAS, The City Council of Georgetown, Texas, finds that it is necessary and essential in the public interest of the health, safety and general welfare of the citizens of the City of Georgetown, Texas, to enact provisions governing the dis- charge of wastes into the city sewage facilities, to read hereafter in full as more particularly provided in the body of this ordinance. NOW, TUIL ORE, BE IT ORDAINED BY THE; CITY COUNCIL OF THE CITY OF GEORGETOWN, TEXAS: Jib( SECTION 1. DEFINITIONS. The following words and phrases shall have the ?j meanings herein ascribed to them. B.O.D., denoting Biochemical Oxygen Demand means the quantity of oxygen utilized in the biochemical oxidation of organic matter by standard methods procedure in five (5) days at twenty (20) degrees C., expressed in parts per million by weight. City means the City of Georgetown, Texas, or any authorized person acting in its behalf. Domestic �iew-age means water -borne wastes normally discharged from sanitary conveniences of dwellings, including apartment houses and hotels, office buildings, factories and institutions, free from storm surface water and industrial wastes. Normal domestic sewage shall mean normal sewage for Georgetown, Texas, in which the average concentration of sna ended materials and five (5) day B.O.D. is estab- lished at two hundred fifty (250� parts per million each, by weight, on the basis of -the normal contribution of twenty hundredths (0.20) pounds per capita. It is further expressly provided that for the purpose of this ordinance, any waste that exceeds the above concentration of suspended materials and/or B.O.D. shall be classified as industrial wastes and made subject to all regulations pertaining there to, whether or not such waste was partially of domestic origin. Garbage means solid wastes from the preparation, cooking and disposing of food, and from the handling, storage and sale of produce. Industrial wastes means all water -borne solids, liquids, or gaseous wastes resulting from any industrial, manufacturing or food processing operation or process, or from the development of any natural resource, or any mixture of these with water or domestic sewage as distinct from normal domestic sewage. Manager means the City Manager or his authorized deputy, agent, or representative. Person, establishment or owner means any indidual, firm, company, association, society, corporation, partnership, or group; their agents, servants or employees. PH means the logarithm (base 10) of the reciprocal of the hydrogen -ion concent- ration of a solution. Properly shredded garbage means the wastes from the preparation cooking, and dispensing of food, exclusive of egg shells, bones, etc., that have been shredded to such degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particles greater than one-half () inch in any dimesion. Public sewer means a sewer in which all owners abutting properties shall have equal rights, and is controlled by public authority. Sanitary sewer means a public sewer which carries sewage and to which storm, surface, and ground waters are not intentionally admitted. Sewage means a combination of the water -carried wastes from residences, busi- ness buildings, institutions and industrial establishments. Sewage works means all facilities for collecting, pumping, treating and disposing of sewage. Sewer means a pipe or conduit for carrying sanitary sewage. Sewage treatment plant means any city owned facility, devices and structures used for receiving and treating sewage from the city sanitary sewer systems. Suspended Solids means solids that either float on the surface, or are in suspension in water, sewage, or other liquids; and which, in accordance with standard methods, are removable by laboratory filtering. Standard methods means the laboratory procedures set forth in the latest edition, at the time of analysis, of Standard Methods for the Examination of Water and Waste Water as prepared, approved, and published jointly by the American Public Health Association, and the American Water Works Association, and the Water Pollution Control.Federation Unpolluted water or rwaste means any w ter or waste containing none of the Cj following: free or emulsified grease or oil; acid or alkali; phenole, or other substances in suspension, colloidal state or solution, and noxious or odorous gases. It shall contain not more than ten parts per million each of suspended solids and B.O.D. The color shall not exceed fifty parts per million. SECTION 2. PROHIBITED WASTES. A. No person shall discharge, or cause to be discharged, into any sanitary sewer any of the following described substances, material, waters, or wastes: (1) Any liquid or vapor having a temperature higher than one hundred fifty (150) degrees Fahrenheit (sixty-five (65) degrees Centi- grade), or any discharge which causes the temperature of the total treatment plant influent to increase at a rate of ten(10) degrees Fahrenheit or more per hour or a combined total increase to a plant influent temperature of one hundred ten (110) degrees Fahrenheit; (2) Any water or wastes which contain wax, grease or oil, plastic, orother substance that will solidify or become discernibly viscous at to eratures between thirty-two'(32) degrees to one hundred fifty7(150) degrees Fahrenheit; (3) Flammable or explosive liquid, solids or gas, such as gasoline, kerosene, benzine, naptha, etc; (4) Solid or viscous substances in quantities capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, whole blood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, slops, chemical residues, paint residues or bulk solids; (5) Any garbage not within definition of properly shredded garbage as defined in SECTION 1 hereof; ' (6) Any noxious or malodrous substance and which can form a gas, which either singly or by interaction with other wastes, is capable of causing objectionable odors; or hazard to life; or forms solids in concentration exceeding limits established in paragraph B. of this section; or creates any other condition deleterious to structures or treatment processes; or requires unusual provisions, attention, or expense to handle such materials. 234 B. Except in quantities, or concentration, or with provisions as stipu- lated herein, it shall be unlawful for any person, corporation or individual, to discharge water or wastes to the sanitary sewer containing: (1) Free emulsified oil and grease exceeding on analysis an average of one hundred (100) parts per million (eight hundred thirty- three (833) pounds per million gallons) of either or both or com- binations of free or emulsified oil and grease, if, in the opinion of the manager, it appears probable that such wastes: (a) Can deposit grease or oil in the sewer lines in such a manner as to clog the sewers; (b) Can over -load skimming and grease handling equipment; (c) Are not amenable to bacterial action and will therefore pass to the receiving waters without being affected by normal sewage treatment processed; or, (d) Can have deleterious effects on the treatment process due to the excessive quantities. (2) Acids or alkalies which attack or corrode sewers or sewage dis- posal structures, or have a pH value lower than 5.5 or higher than 9.5; (3) Cyanide or cyanogen compounds capable of liberating hydrocyanic gas on acidification in excess of two (2) parts per million by weight as CN in the wastes from any outlet into the public sewers; (4) Materials which exert or cause: (a) Unusual concentrations of solids or composition; as for example; total suspended solids of greater than 250 parts per million of inert nature or such as Fuller's Earth and or total dissolved solids such as sodium chloride, or sodium sulfate; (b) Excessive discoloration; (c) Biochemical oxygen demand or an immediate oxygen demand greater than two hundred (250) parts per million; (d) High hydrogen sulfide content, or (e) Unusual flow and concentration shall be pretreated to a concentration acceptable to the Georgetown Water and Sewer System if such wastes can cause damage to collection facilities, impair the processes, incur treatment cost exceeding those of normal sewage, or render the water unfit for stream disposal or industrial use. SECTION 3. PRETREATMENT AND CONTROL OF INDUSTRIAL WASTES. A. Persons or owners discharging industrial wastes which exhibit any of the prohibited wastes set out in this ordinance shall be required to pretreat said wastes or otherwise dispose of such wastes so as to make the remaining waste acceptable to the City of Georgetown prior to admission of said waste into a sanitary sewer. B. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment and control facilities shall be submitted for the approval of the City of Georgetown, and no construction of such facilities shall be commenced until approval is obtained in writing. Preliminary treatment and control facilities shall be constructed so as to provide all of the following: (1) Prevention of prohibited waste from entering a sanitary sewer; (2) Control of the quantities and rates of discharge of industrial wastes into a sanitary sewer; and, (3) An accessible entry so that any authorized employee of the City of 23 ) Georgetown may readily and safely measure the volume and samples of the flow prior to the admission of said industrial wastes into a sanitary sewer. C. When preliminary treatment and control facilities are provided for any water and wastes, they shall be maintained continuously in satisfactory and effect- ive operation by the owner at his expense. D. The manager and other duly authorized employees of the City of Georgetown acting as his duly authorized agent and bearing proper credentials and indent- ification, shall be permitted to gain access to such properties as may be necess- ary for the purpose of inspection, observation, measurement, sampling and testing of sewage and/or industrial wastes. f SECTION 4. SURCHARGE FOR WASTES OF ABNOIWAL STRENGTH. The service charge for any person, firm, owner or corporation discharging "wastes into the system is twenty-five per cent (25%) of the total cost of water purchased by the owner for that billing period provided that the City meter is the only source of water used by the owner and provided that the B.O.D. in the waste water or the suspended materials does not exceed the normal concentration of two hundred fifty (250) ppm. When either the B.O.D. or the suspended solids or both are found to exceed O the stated two hundred fifty (250) ppm at the point entering the City's system, L a surcharge shall be applied to the billing rate by multiplying the normal base rate by the factor.obtained from dividing the actual measured I.O.D. by two hundred fifty and also by the factor obtained from dividing the actual measured suspended solids by two hundred -fifty, each such factor to be applied individually and only when greater than one. The surcharge will be made for each factor that exceeds one and shall be additive. The determination of B.O.D. and suspended materials shall be by an inde- pendent laboratory selected by the City. The time of selection of the sample shall be at the sole discretion of the City. The applicable surcharge determined by such tests shall be retro-active for two billing periods and shall continue for six (6) billing periods unless subsequent tests determine that the surcharge should be further increased. When any each test made at the discretion of the City shows that a sur- charge shall be applied, continued or increased over the base rates, which ever is applicable, then the owner shall be billed at the rate of Five Dollars ($5.00) for each test to cover the costs of sampling, mailing and handling plus the laboratory fees. When a surcharge is in effect, the test will be made at least each fifteen (15) days. When such tests made at the City reveals that the surcharge is no longer applicable, then no costs will be made to the owner for such test or test&. SECTION 5. AUTHORITY TO DISCONNECT SERVICE. The City shall retain the right to disconnect waste disposal service in the following circumstances: A. Where acids or chemicals damaging to sewer lines or treatment processes are released to the sewer causing rapid deterioration of these structures or interfering with proper treatment of sewage, the manager is authorized immediately to terminate service by such measures as are necessary to protect the facilities; B. Where any governmental agency informs the City that the effluent from the treatment plant is no longer of a standard permitted for surface runoff and it is found that the owner is delivering waste water to the City's system that cannot be sufficiently diluted by mixing with the City's waste or requires treat- ment that is not provided by the City as normal domestic treatment. In this instance, the City shall immediately supply the owner with the governmental agencies report and provide the owner with all pertinent information. The owner's waste line will then be disconnected when the City is informed that it can no longer continue to release their effluent for surface runoff. The owner's waste treatment service shall remain disconnected until such time that the owner has provided additional pretreatment facilities designed to remove the objectionable cause from owner's industrial wastes; 236 C. Where the owner delivers his waste water at an uncontrolled, variable rate in sufficient quantity that it causes an imbalance in the sewage treating system. SECTION 6. REPEALER. All ordinances and parts of ordinances inconsistent with or in conflict with the provisions of this ordinance shall be and the same are hereby expressly repealed. SECTION 7. PENALTY. Any person, firm or corporation violating any provisions of this ordinance shall be guilty of a misdemeanor, and shall upon conviction be fined in a sum not to exceed Two Hundred Dollars ($200.00), with each day of violation cons- tituting a separate violation of this ordinance. SECTION 8. PUBLICATION. The City Secretary shall cause the publication of the caption and penalty clause of this ordinance in two consecutive issues of the official paper of the City of Georgetown, Texas, and said ordinance shall become effective ten (10) days after the date of its passage. SECTION 9. SEYEHABILITY.
