The property owner shall pay to the City sewer service charges accruing from the date of connection to the date of discovery and thereafter. For an unauthorized connection, the date of connection shall be the date water service commenced unless the property owner provides clear and convincing evidence to the contrary. The amount of accrued charge shall be based on the sewer service rates existing as of the date of discovery.

(a) No connection shall be made nor permitted to the trunk sewers which admits wastes not complying to the discharge and waste requirements of this Article.

(b) No person shall knowingly discharge or deposit or allow discharge into sewers of solids or fluids creating nuisances, or which are detrimental to the functioning of sewer or to the treatment and disposal facilities and processes of the City.

(c) The following wastes are prohibited:

(1) Uncontaminated cooling water.

(2) Rainwater, storm water, groundwater, street drainage, subsurface drainage, yard drainage, including evaporative type air cooler discharge water.

(a) The following wastes may be discharged with a permit:

(1) Brines, including brines produced in the regeneration of water softeners.

(2) Swimming pool waste water discharges between twelve midnight to six a.m.

(3) Cesspool or septic tank pump trucks from within the boundaries of improvement Cities.

(4) Industrial wastes.

(b) Each industrial waste discharge will be considered individually, giving due consideration to its effect upon the trunk sewers and the treatment and disposal facilities and processes of the City. In addition to limitations on industrial wastes imposed by the administering authority, the following general limitations shall apply to industrial wastes:

(1) Material which will settle out in the sewers, such as sand or metal filings, shall not be discharged to the sewers. Waste waters containing such materials must be passed through sand traps or other suitable structures before discharge to the sewer.

(2) Oils and greases shall not be discharged to the sewer system in concentrations greater than one hundred (100) mg/L.

(3) Unreasonable or unnecessarily large amounts of suspended solids shall not be discharged into the sewer.

(4) Pollutants, including oxygen demanding pollutants (BOD, etc.) shall not be discharged into the sewer at flow rates or concentrations causing interference with the Water Reclamation Facility or enhance the formation of excessive sulfides in the collection system.

(5) Wastes of strong odors, such as mercaptans, shall not be discharged into the sewer.

(6) Dissolved sulfides in wastes discharged into the sewer shall not exceed a concentration of 0.1 pH.

(7) Acids shall not be discharged into the sewer unless neutralized to a pH value of 6 or above. Highly alkaline wastes will usually be accepted, except where they may cause incrustation of sewers. Nitric acid requires special consideration. The Director of Public Works shall be consulted prior to making such discharges.

(8) Pollutants which result in the presence of toxic gases, vapors or fumes in quantities that could endanger worker health and safety in the collection system.

(9) Contaminated cooling water blow down, or bleed, from cooling towers or other evaporative coolers and when cooling is done by using only heat exchange, without using evaporative cooling, shall not be discharged to the sewer.

(10) Industries shall segregate sewage and industrial wastes from roof and yard run-off. Roof and yard run-off shall not be discharged to the sewer.

(11) The temperatures of discharges shall not exceed one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Celsius). Where the quantity of discharge represents a significant portion of the flow in a particular sewer, it may be necessary to lower the temperature further.

(12) Chemical solutions containing nitric acid or salts thereof in concentrations above 5% by weight, and volumes in excess of three hundred (300) gallons shall not be discharged into the sewer. Industries desiring to dispose of such wastes may consult the City as to permissible disposal methods.

(13) Wastes containing boron, fluorides, chlorides and sodium or potassium or other dissolved solids which will cause the effluent of the City's treatment facilities to exceed the requirements of the Regional Water Quality Control Board shall not be discharged into the City's sewers.

(14) Pollutants that could create a fire or explosion hazard in the sewers or treatment facility shall not be discharged. This includes, but is not limited to, discharges with a closed cup flash point of less than one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Celsius) using test methods specified in 40 CFR261.21.

The following pollutants limits to protect against pass-through and interference. No one shall discharge or cause to be discharged any waste containing in excess of the following instantaneous maximum allowable discharge limits:

The discharge concentration of a pollutant not listed shall not exceed the Maximum Contaminant Level (MCL) for the pollutant established by the California Department of Health Services for drinking water.

(a) On promulgation of the Categorical Pre-treatment Standards for a particular industry sub-category, the Federal Standard shall immediately supersede the limitations imposed under this Article. The Federal Standard is more stringent than the limitations imposed under this Article for sources in that sub-category. The Director of Public Works shall notify Users of the applicable requirements under the General Pretreatment Regulations, Solid Waste Disposal Act, and the Act.

(b) If additional pretreatment or operation and maintenance is required to meet Pretreatment Standards, the shortest schedule by which the user will provide such additional pretreatment shall be used. The completion date shall not be later than the compliance date established for the applicable Pretreatment Standard.

(c) The following conditions shall apply to the schedule:

(1) The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the User to meet the applicable Pretreatment Standards e.g., hiring an engineer, completing preliminary plans, completing final plans, executing contract for major components, commencing construction, completing construction, and so forth.

(2) No increment referred to in Paragraph (1) shall exceed nine (9) months.

(3) Not later than fourteen (14) days following each date in the schedule and the final date for compliance, the user shall submit a progress report to the Director of Public Works including, as a minimum, whether it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for the delay, and the steps being taken by the user to return the construction to the schedule established. In no event shall more than nine (9) months elapse between such progress reports.

(a) Within ninety (90) days following the date for final compliance with applicable Pretreatment Standards or, in the case of a New Source, following commencement of the introduction of waste water into POTW, any user subject to pretreatment Standards and Requirements shall submit to the Director of Public Works a report indicating the nature and concentration of pollutants in the discharge from the regulated process which are limited by Pretreatment Standards and Requirements and the average and minimum daily flow for those process units in the user facility limited by such Pretreatment Standards or Requirements. The report shall state whether the applicable Pretreatment Standards or Requirements are being met on a consistent basis and, if not, what additional operation and maintenance or Pretreatment is necessary to bring the user into compliance. This statement shall be signed by an authorized representative of the user, and certified to by a qualified professional.

(b) Any user subject to a Pretreatment Standard, after the compliance date of such Pretreatment Standard, or, in the case of a New Source, after commencement of the discharge into the POTW, shall submit to the Manager of Water Reclamation Operations during the month of June and December, unless required more frequently in the Pretreatment Standard or by the Director of Public Works, the report indicating the nature and concentration of pollutants in the effluent limited by such Pretreatment Standards. This report shall include a report of daily flows which during the reported period exceeded the average daily flow reported in the paragraph above. At the discretion of the Director of Public Works and in consideration of such factors as local high or low flow rates, holidays, budget cycles and so forth, the Director of Public Works may agree to alter the monitoring which the above reports are to be submitted.

(c) The Director of Public Works may impose mass limitations on users using dilution to meet applicable Pretreatment Standards or Requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by subparagraph (a) of this paragraph shall indicate the mass of pollutants regulated by Pretreatment Standards in the effluent by the users. These reports shall contain the results of sampling and analysis of the discharge, including the flow and nature and concentration, or production and, where requested by the Director of Public Works, mass of pollutants limited by the applicable Pretreatment Standards. The frequency of monitoring shall be prescribed in the applicable Pretreatment Standards. Analysis shall be performed in accordance with the procedures established by the Administrator pursuant to Section 304(g) of Act and contained in 40 CFR, Part 136 amendments thereto or with any other test procedures approved by the Administrator. Samplings shall be performed in accordance with the techniques approved by the Administrator.

The City shall annually publish a list of users not in compliance with Pretreatment Requirements or Standards at least once during the previous twelve (12) months. The notification shall also summarize enforcement action taken against the user during the same period.
