GENERAL PROVISIONS
(A) Unlawful. It is unlawful to discharge or to allow to discharge septage and/or scavenger wastes into the system without a septage discharge permit.
(B) Permit to discharge. All person or companies wishing to operate a commercial dump station, or to discharge septage or scavenger wastes into the sewer system must first obtain a scavenger waste discharge permit from the Department. Permit applications shall include information on company ownership, identification and license number of all trucks to be used for delivery of waste to sewer facilities. It shall also include truck capacity and other information relating to the method of metering the septage or scavenger wastes into the system. Permit applications shall be signed by a responsible owner or manager of the company applying for permission to discharge. All waste hauling equipment and waste collection tanks operated by companies with permits shall be registered with the Department and shall be identifiable by display of an assigned registration number and the truck or tank capacity in gallons.
(C) Permit to operate dump station. All persons wishing to operate a dump station for the purpose of collection of septage from non-continuous sources shall first apply for and receive a dump station permit from the Department. All dump stations must consist of holding tanks with the capability of being sealed and locked, thus prohibiting collection when not in use. Each tank must be independently connected to the wastewater collection system and contain a lockable valve by which the discharge of the collected septage shall be regulated.
(1) The permits provided for in this section shall be issued by the Department to all applicants who comply with the terms and conditions set forth in this section and who pay the permit fee set annually by Council resolution, which fee reasonably corresponds to the expenses incurred in processing the application, and which fee is proportionally greater for accepting septic and/or scavenger wastes for discharge into the system.
(2) The permits issued, as provided for in this section, shall expire one year after the date of issuance.
(3) Non-compliance with any part of this section or subsequent regulations shall subject the permit holder to revocation of permit to utilize the services of the town sewer system for disposal of septic and/or scavenger wastes. Re-issuance of permit to discharge after revocation shall be at the discretion of the Department and shall be made subject to such conditions as it deems appropriate.
(D) Regulations. The Council, by resolution, shall establish such regulations as deemed necessary to control the discharge of scavenger wastes to the sewer system.
(E) Provision of services.
(1) Normal wastes from septic tanks, sewage treatment plants and the like shall with the appropriate permit be discharged routinely. Permission to discharge other wastes that are not readily biodegradable or are not known to be compatible to the operation of wastewater treatment plants shall be refused. Special request shall be made to the Department prior to discharge of any material of questionable acceptability. Some specific reasons for refusal of service shall include:
(a) Material deleterious to treatment plant operation or operators, such as oils, greases, gasoline, toxins, volatile solvents, sand, metallic particles or paints;
(b) Materials which would cause unusual expense in handling and treatment unless prior arrangements have been made for the payment of additional costs of service; and
(c) Materials which would inhibit the performance of the treatment plant, such as acids, plating wastes or toxic materials.
(2) The discharge of septic and/or scavenger wastes shall be permitted only at locations and during such hours as shall be established by the Department. The discharge of septic and/or scavenger wastes to the sewer system at any other location is prohibited.
(F) Dump stations. Discharge of septage into the wastewater collection system from commercial dump station collection tanks shall be supervised by a Department representative according to the following procedure.
(1) Amount of septage collected in tank(s) shall be verified by department representative. Tank(s) shall then be sealed by Department representative to prevent further collection of septage.
(2) Tank(s) will be opened to allow septage discharge into collection system at an acceptable discharge rate to be determined by Department representative based upon current system loading.
(3) Upon notification that tank(s) are empty, a Department representative shall unseal tank for acceptance of septage.
(G) Fees and charges. Fees and charges for treatment of normal septage and/or scavenger wastes shall be based on the costs of providing such services and on the expected overall average characteristics of such discharges which shall be designated as 500 mg/l BOD and 500 mg/l SS. The department shall designate characteristics on which to base charges in special situations, such as discharges from sewage holding tanks, on submission of proof that waste discharges have other than expected overall average concentrations and with provision of positive identification procedures. Charges shall be billed at monthly intervals or at the discretion of the Department and shall be considered delinquent if not paid within 30 days of billing date. Delinquency in payment shall be on the basis of revocation of permit. The actual rates and categories will be set by resolution which shall be amended from time to time. The rate shall be established in compliance with the public hearing requirements of A.R.S. § 9-511.01. The fees shall be set periodically and shall be based upon:
(1) The actual measured discharge or truck capacity as appropriate;
(2) The amount of BOD contained in the discharge;
(3) The amount of suspended solids contained in the discharge;
(4) A service fee for each load discharged; and
(5) Such other factors as are determined by the Council as pertinent.
(Prior Code, § 16-2-4)
(A) Each permittee shall provide protection from accidental discharge of prohibited materials or other wastes regulated by this code.
(B) For countermeasures to be taken by the Department to minimize damage to the sanitary sewer system and/or degradation of the receiving waters, the permittee shall notify the Department immediately upon accidentally discharging wastes in violation of this code. This notification shall be followed within 15 days of the date of occurrence by a detailed written statement describing causes of the accidental discharge and the measures being taken to prevent future occurrence. Such notification will not relieve the permittee of liability for any expense, loss or damage to the sanitary sewer system or for any fines imposed on the Department on account thereof and/or for any enforcement action pursuant to this occurrence.
(C) In order that officers, agents and employees of permittees be informed of the Department’s requirements, the permittee shall make available to their employees copies of this code, together with such other wastewater information and notices which may be furnished by the Department from time to time for the purpose of improving and making more effective water pollution control. A notice shall be furnished and permanently posted on the permittee’s bulletin board advising officers, agents and employees whom to call in case of an accidental discharge in excess of the limits authorized by the permit.
(D) Any possible connection or entry point for a hazardous and/or prohibited substance to the permittee’s plumbing or drainage system shall be appropriately labeled to warn operating personnel against discharge of such substance in violation of this section.
(Prior Code, § 16-2-5)
(A) The Department shall determine the acceptability or unacceptability of any discharge to the system. Such a determination shall be made on the basis of sound engineering and operational evaluations, taking into consideration the nature and concentration of the discharge, its point of entry into the system, its compatibility with other discharges in the system, its compatibility with the treatment facility receiving it and all other factors pertinent to the effect of the discharge on any part of the system or treatment process. The Department shall impose charges on any user of the sewage works who discharges wastes having a strength greater than normal sewage or containing non-permissible quantities or prohibited substances into the public sewer system. The charges so imposed shall be based on the extra costs incurred by the Department in surveillance, sampling and testing of the discharges, additional operating and maintenance expenses and any other actions required to identify, handle, process or supplement normal activities due to the unauthorized discharge of excessive strength or unusual character wastes, plus overhead charges. Failure by a user to pay the charges and to provide such corrective measures as may be required to prevent further unauthorized discharges, after due notice by the Department and being given a reasonable time to comply, shall be sufficient cause to discontinue sewer service to the premises.
(B) Unacceptable discharges shall include, but not necessarily be limited to, those which have been determined by the Department to:
(1) Contain materials or substances which would constitute a hazard to life of personnel engaged in inspection, maintenance and operation of the system;
(2) Contain materials or substances which are toxic, as defined in this code;
(3) Contain materials or substances which are in any way deleterious to any part of the system;
(4) Contain concentrations of any toxic or deleterious materials or substances in excess of any limits set thereon, in accordance with this code;
(5) Cause the Department to incur excessive expense in the handling or treatment thereof;
(6) Be incompatible with the treatment process or inhibit the performance of the treatment process at the town wastewater facility;
(7) Be of such volume or contain such BOD, suspended solids or other material load which could cause the treatment facility to exceed its design capabilities;
(8) Cause a treatment facility of the Department to fail to meet effluent requirements set by state and federal regulatory agencies or cause such effluent to have a degrading effect on the receiving body of water; and
(9) Contain viable pathogenic organisms in such quantities as to be a hazard to public health.
(C) The Department shall refuse the service of the facilities to any person whose discharge is determined by the Department to be unacceptable in accordance with the provisions of this chapter.
(D) No person shall release or cause to be released or allow to run, leak or escape into the sewer system any discharge containing any materials or substances considered by the Department to be toxic, as defined in this code, or to be in any way deleterious to any part of the sewer system or treatment process. Certain materials shall, by their nature, be considered by the Department to be toxic or deleterious, except in small quantities or concentrations. Such materials or substances shall include by not necessarily be limited to:
(1) Construction materials, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, fur, waste or any solid or viscous substance capable of or causing obstruction to the flow in sewers or other interference with the proper operation of the sewer system;
(2) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquids, solids or gases;
(3) Steam or hot water above 105°F (40°C);
(4) Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 33°F and 150°F (1°C and 65°C);
(5) Any water or wastes having a pH lower than 5.5 or higher than 9.5 or having any other corrosive property apt to cause damage or hazard to structures, equipment of the sewer system or personnel employed in its operation;
(6) Any water or waste contain readily releasable cyanide (cyanide released at a temperature of 150°F/65° and pH=2.5) in excess of two mg/l; any water or water containing total cyanide in excess of five mg/l;
(7) Coal tar, its derivatives and waste;
(8) Any liquids or wastes containing toxic, radioactive, poisonous or other substances in sufficient quantities or rate of flow as to injure or interfere with any of the sewage treatment process, to cause corrosive structural damage, to constitute a hazard to human beings or animals or to create any hazard in the receiving waters; and
(9) Any storm water, surface water, ground water, roof runoff, surface drainage, cooling water or unpolluted process water.
(E) Certain toxic substances and pathogenic bacteria, admission of which into the system would otherwise be prohibited, shall be acceptable in a discharge if reduced by treatment at the source to a point that it will meet the general purposes of these rules and regulations or come within any applicable standards set thereon now or hereafter in accordance with these regulations, or discharge in such small concentrations so as to not be injurious to personnel; sewers; any biochemical, biological or other sewage treatment process or receiving water. Such substances shall include, but not necessarily be limited to:
(1) Any alcoholic, antibiotics, arsenic, bromine, iodine, chlorine, copper, copper salts, creosols, creosotes, fluorine, formaldehydes, mercury, phenols, phenol derivatives, silver, silver compounds, toxic dyes (organic or mineral) or zinc;
(2) Any strong oxidizing agents, such as chromates, dichromates, permanganates or peroxides;
(3) Any chemical compounds producing toxic, flammable or explosive gases either upon acidification, alkalization, oxidation or reduction;
(4) Any strong reducing agents such as nitrates, sulfides, sulfites and thiosulfates; and
(5) Any waste from industrial process, hospital procedures or commercial processes containing viable pathogenic organisms.
(F) The following table lists the maximum allowable values of certain materials in or characteristics of wastewater entering the sewer system. The Department reserves the right to establish standards for substances not contained in this list. In setting additional standards, the Department will generally follow the standards of the Water Pollution Control Federation. In defining and interpreting the values of the following table, reference shall be made to Standard Methods for the Examination of Water and Wastewater, American Waterworks Association, latest edition.
(G) (1) Any discharge to the sewer system containing garbage may be made acceptable by means of grinding and dilution; provided, however, that, the installation of and operation of any garbage grinder equipped with a motor are subject to review and approval by the Department prior to such installation and operation and are subject to periodic inspection by the Department thereafter.

(2) The above limitations are intended to apply generally to all industrial users within the sewer system. If, and when, state and federal regulatory agency regulations require a specific pretreatment concentration for a specific industry, whichever is the more stringent concentration level between these regulations shall apply.
(Prior Code, § 16-2-6)
(A) Pretreatment will be required in the following instances and the Department shall submit to the applicant the pretreatment levels which must be obtained.
(1) If the Department determines upon the initial application for a permit under this section that the proposed industrial waste must be pretreated by the applicant to lower the level of any of the components of the industrial waste discharge to the sewer.
(2) In the event that the Department must improve the discharge from its wastewater treatment plant or plants, the Department shall require that a permit holder install or enlarge pretreatment facilities to lower the affected component of the permittee’s industrial waste discharge.
(3) If any wastewater prohibited under the conditions of this code is produced, such producer shall pretreat the wastewater to the extent required to comply with the standards established herein before discharging to any sewer.
(4) The acceptability of a pretreatment method for any given discharge, an application for which has been made in accordance with this section and the terms for the installation and use thereof, shall be reviewed by the Department. Such a review shall be made on the basis of sound engineering and operational evaluation, taking into consideration all factors pertinent to the effect of the discharge, both before and after pretreatment on any part of the system.
(5) Pretreatment facilities shall at all times be subject to inspection by the Department in order to determine if such facilities are efficiently performing the function for which they are installed.
(6) If the Department determines that a permittee, because of plant expansion and/or changes in plant operations, has increased either the strength or volume of the discharge, the Department may require additional pretreatment to lower the level of the volume and/or any components of the industrial waste before discharge, unless such permittee has previously made industrial cost recovery payment for reservation of additional industrial capacity.
(7) Pretreatment facilities required under divisions (A)(1) through (A)(7) above shall be provided, operated and maintained at the permit holder’s expense.
(B) Any sludge or other material removed from the industrial waste by the pretreatment facility shall be disposed of in accordance with applicable federal, state and local laws.
(C) (1) Dilution of waste discharged to the sanitary sewer system is prohibited, whether accomplished by the combination of two or more waste streams by a producer or producers, or by the addition of other liquids solely for the purpose of diluting the quality of the waste discharge.
(2) One or more producers may, upon application and approval by the Department, combine industrial waste streams prior to discharge to the town sanitary sewer system if, and only if, such combination of industrial waste streams produces a combined discharge of better quality than the two industrial waste streams would have been if discharged separately. However, if one or more producers are allowed to mix industrial waste streams to produce a better discharge, the user charge established herein, based on the quality of its industrial waste streams prior to combination, shall be paid to the town.
(D) (1) Detailed plans showing any pretreatment facilities shall be submitted to the Department for approval before construction of the facilities. The review of such plans will in no way relieve such permit holders from the responsibility of modifying and operating the facilities to produce an effluent complying with the established conditions of the permit and federal regulations. Any subsequent, significant changes in the approved facilities or methods of operation shall be reported to the Department and must be reviewed and approved by the Department as complying with the provisions herein established.
(2) Furthermore, all facilities, methods of operation and discharges must comply with the rules and regulations contained in 40 C.F.R. part 403.
(E) After the construction plans for such pretreatment plants have been approved and a permit issued, the plans shall be placed on file in permanent reproducible form with the Department without cost to the Department before a connection permit will be issued.
(Prior Code, § 16-2-7)
(A) There shall be a penalty imposed for violation of any of the following requirements, conditions, limitations or restrictions established in this code. The fines shall be those as set forth for any code violation:
(1) Exceed quantity discharge limitations as set forth herein or as made part of an industrial wastewater permit;
(2) Permit the discharge of excessive concentrations of substances limited by this chapter or by an industrial wastewater permit issued pursuant to this chapter;
(3) Permit the discharge of any substance prohibited by this code or by a permit issued pursuant to this chapter;
(4) Fail to pay any applicable sewer charge established by this code; and
(5) Knowingly misrepresent or omit any pertinent information from application permits or reported required by this code.
(B) The imposition of a fine pursuant to this code shall not preclude the Department from taking any other action necessary to recover fees, penalties or damages due and owing and arising out of the same occurrence.
(Prior Code, § 16-2-8) (Ord. 98-04, passed - -1998)
(A) All property owners desiring the connection of the improvements on their property to the sewer system of the town shall grant to the town, at no charge, those easements necessary to properly effectuate the sewer connection desired.
(B) All easements granted to the town shall be subject to the following restrictions and conditions of use.
(1) No person, firm or corporation having charge of property subject to easement in favor of the town shall hereafter construct, build or establish a building upon the property subject to said easement. A BUILDING means a house, commercial building, industrial building or any structure of a size or construction that the moving thereof would cause great inconvenience to any person.
(2) Should the owner of the property subject to an easement in favor of the town construct a building thereon in violation of this code, the town shall employ individuals to clear said property and charge the costs of the same to the owner of the property. Nothing contained herein shall obligate the town to compensate the owner of the property subject to the easement for the value of a “building” cleared. The town shall take those steps as are required to work in the easement and preserve the improvement, rather than clear the improvements.
(C) No person shall excavate deeper than three feet upon the property subject to the easement in favor of the town without having first obtained a permit therefor, as herein required. Such permit shall be issued by the town. Applications for a permit to excavate upon property subject to easement in favor of the town shall be made in writing to the town and shall state thereon specifically the size of the space intended to be excavated and the purpose for the excavation.
(D) No person shall plant any trees or shrubbery upon the property subject to the easement in favor of the town without having secured a permit therefor. Applications for such permit shall be made to the town. All trees and shrubs so planted shall be placed subject to the direction and approval of the town. No boulders, benches or fences shall be built or maintained upon the property subject to the easement unless approved by the town.
(E) In the event any improvements are constructed within the boundaries of the easement and these create any additional costs to the town because it must incur additional expenses to repair, install or replace its sewer, the property owner shall be charged all additional costs incurred.
