(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.
