(a) Purpose. The purpose of this section is to establish rules and regulations concerning discharges to the sewerage system, including determining the acceptability or unacceptability of such discharges and the pretreatment thereof, establishing specific limitations on certain discharges and establishing certain other system standards.
(b) Right of Entry: Construction of Manholes. The City shall at all times have free access to the premises of any user of its facilities and to the premises of any person reasonably believed by the City to be a user or a possible user of its facilities, for the purposes of inspecting, sampling or testing the discharge emanating therefrom, or any discharge which may emanate therefrom, in order to determine whether such discharge or potential discharge is acceptable or unacceptable to the City. Where necessary, the City may require the owner of any premises which discharges to the system to install a suitable control manhole, together with such necessary meters and other appurtenances in the building sewer to facilitate the observation, sampling and measurement of the discharge or potential discharge. Such a manhole, when required, shall be constructed in accordance with plans approved by the City. The manhole shall be installed at the owner's expense and shall be maintained by the owner so as to be safe and accessible at all times.
(c) Determination of Acceptability or Unacceptability of Discharges. The City shall determine the acceptability or unacceptability of any discharge to the sewerage system. Such a determination shall be made on the basis of sound engineering and operational evaluations, and take into consideration the nature and concentration of the discharge, its point of entry into the system, its compatibility with other discharges in the system and 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 operational evaluation shall include compulsory surveys of discharge from commercial and industrial users.
(d) Unacceptable Discharges. Unacceptable discharges shall include those which have been determined by the City to:
(1) Contain materials or substances which would constitute a hazard to life and limb or personnel engaged in the inspection, maintenance and operation of the system;
(2) Contain materials or substances which are toxic, or deemed hazardous;
(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 chapter or State or Federal regulations;
(5) Cause the City to incur excessive expenses in the handling or treatment thereof;
(6) Be incompatible with the treatment process or inhibit the performance of the treatment process at the Municipal treatment facility;
(7) Be of such volume or contain such BOD, suspended solids or other material load (slug) as would cause the treatment facility to exceed its design capabilities;
(8) Cause the treatment facility 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;
(9) Contain viable pathogenic organisms in such quantities as to be a hazard to public health; or
(10) Cause the treatment facility to fail to meet effluent requirements as established under its NPDES permit.
(e) Refusal of Service. The City may refuse the service of the Municipal treatment facilities to any person whose discharge is determined by the City to be unacceptable in accordance with this section.
(f) Pretreatment Permitted. Any person whose discharge has been determined by the City to be unacceptable in accordance with this section may apply to the City for permission to pretreat such discharge by the use of a method of pretreatment designed to render such discharge acceptable.
(g) Pretreatment Methods. The acceptability of a pretreatment method for any given discharge, an application for which has been made in accordance with division (f) of this section and the terms for the installation and use thereof shall be reviewed by the City. Such a review shall be made on the basis of sound engineering and operational evaluations and take into consideration all factors pertinent to the effect of the discharge, both before and after pretreatment, on any part of the system.
(h) Inspection of Pretreatment Facilities. Pretreatment facilities shall at all times be subject to inspection by the City in order to determine if such facilities are efficiently performing the function for which they are installed.
(i) Cost of Pretreatment. All costs incident to pretreatment and all expenses incident to the acquisition, installation, operation, maintenance and repair of pretreatment facilities shall be borne by the user. In addition, any extraordinary administrative or investigative expenses incurred by the City, as a result of the installation and use of pretreatment facilities, shall be charged to the user.
(j) Discharge of Certain Materials and Substances Prohibited. No person shall release or cause to be released or allow to run, leak or escape into the sewerage system any discharge containing any materials or substances considered by the City to be toxic or in any way deleterious to any part of the sewerage system or treatment process. Certain materials shall, by their nature, be considered by the City to be toxic or deleterious, except in small quantities or concentrations.
