ARTICLE III Special Restrictions ® Vehicle Servicing Facility Section 4. Any facility maintained for the servicing or repair of roadway machinery shall install and maintain a sand-and-oil interceptor. Waste waters from toilets shall not be allowed to pass through this interceptor , but all waste waters arising from the servicing and repair of vehicles shall pass through this interceptor before discharge to a public sewer of the City of Redlands . If the vehicle servicing facility does not include facilities for the washing of more than one vehicle at a time, the interceptor shall have an operation -fluid capacity of not less than 6 cubic feet and an accessible effective water surface not less than 4 square feet. "Accessible effective water surface" is here understood to mean a surface which is easily accessible for cleaning and which at the same time will retain oil floating on the surface of water passing through the trap under conditions of use. If the vehicle servicing facility has facilities for washing or otherwise cleaning more than one vehicle at a time, the interceptor shall have an operating fluid capacity of at least 12 cubic feet and> an accessible effective water surface of at least 6 square feet , and shall be as much larger than this as is necessary so that a seven-day accumulation of sand and oil will. 'not together fill more than 2576' of the fluid capacity. The interceptor shall be designed so as to retain any oil and grease which will float and any sand which will settle. It shall be water tight and structurally sound and durable. It shall be easily accessible for cleaning and also for inspection by the Public Works Director. Section 5. Any interceptor legally and properly installed at a vehicle servicing facility before the effective date of this ordim race shall be acceptable as an alternative to the interceptor specified in Section 4, provided such interceptor is effective in removing sand and oil and is so designed and installed that it can be inspected and properly maintained. If the Public Works Director finds either by engineering -4- knowledge or by observation, that an interceptor is incapable of retaining adequately the sand and oil in the waste water flow from a vehicle servic- ing facility, he shall condemn such interceptor and declare that it does not meet the requirements of this ordinance. Section 6. The Public Works Director shall maintain a file, available for public use, of suitable designs of sand-and-oil interceptors. This shall be for informational purpose. Installation of an interceptor of a design shown in this file) or of any design meeting the size requirements set -forth in this ordinance shall not impute any liability to the City of Redlands for the adequacy of the interceptor under actual conditions of use. It shall not relieve the owner or proprietor of responsibility for keeping sand and oil out of the sewer . If his interceptor is not adequate under the conditions of use, he shall construct one which is effective in accomplishing the intended purpose. Section 7. The Plumbing Official shall not approve the plumbing of a vehicle servicing or repairing facility if it does not have a sand-and- oil interceptor meeting the requirements of this ordinance. Section S. The sand-and-oil interceptor of a vehicle servitiing facility shall be properly maintained. It shall be cleaned as often as is necessary to assure that sand and oil do not accumulate to impair the efficiency of the interceptor . When an interceptor is> cleaned, the accumulated sediment and floating material shall be removed and legally disposed of otherwise than to a sewer . An interceptor is not considered to be properly maintained if for any reason it is not in good working condition. It is not considered to be properly maintained if sand and oil accumulations total more than 257 of the operating fluid capacity. The owner of any vehicle servicing facility, the lessee and sub-lessee if there be such, and any proprietor , operator or superintendent of such facility are individually and severally liable for any failure of proper maintenance of such interceptor . ARTICLE IV Special Restrictions - Water Softening Wastes Section 9. It shall be unlawful for any person (including but not limited to persons owning or operating restaurants , hotels, schools, vehicle servicing facilities , wash racks , garages , establishments for regeneration of water softener apparatus , places of retail business or multiple residence dwellings) excepting where water service is to a single family dwelling, to install, replace, enlarge , use or maintain any apparatus for softening all or any part of the water supply to a property at a rate exceeding 15 gallons per minute, if such apparatus is of a find that , due to addition of chemical constituents limited in Article V produces , in any phase of its use or servicing, any waste water with a mineral content higher than that of the water supply of the property. Such apparatus may be installed if arrange- ments are made to dispose of the waste water , as set forth in Section 10 by other means than that of discharge to the sewers of Redlands or to the ground in any place where it might pollute any usable water supply. Such apparatus includes zeolite and resinous ion-exchange softeners or demineral- izers , and other like devices . The regeneration of ion-exchange softeners in commercial soft-water service establishments and the addition of ion exchange materials to water softeners is included in the operations limited by this Section. Section 10. Within ninety (90) days after the effective date of this ordinance, any person desiring to install, enlarge, replace, maintain or use any water treating apparatus of the kind described in Section 9, or to regenerate ion-exchange water softeners in a commercial establishment , or to add ion-exchange materials to any water softeners excepting where water is to a single family dwelling, shall submit to the Public Works Director a letter describing the intended installation or alteration and describing the arrangements which will serve to prevent improper discharge of the waste water . Within' ninety (90) days the Public Works Director shall reply stating whether or not the disposal arrangements are adequate to insure against the addition of mineral salts to the sewage or the ground. No person shall install, replace, enlarge or operate a water-treating apparatus of the kind described to be unlawful in Section 9, after one-hundred eighty (180) days following the '61fective date of this ordinance unless he blas a letter fromthePublic Works Director approving as satisfactory the proposed arrangements for disposal of the waste water , except that the Public Works Director shall grant such reasonable extensions of time in excess of the one-hundred eighty (180) day period as may be necessary for plant altera- tions`, changes in process or the design, acquisition, manufacture, installa- tion and testing of the committed treatment or other facilities which additional time the Public Works Director agrees is required to effect compliance. Such apparatus may be operated only so long as the method of waste water disposal is as approved by the Public Works Director. Altera- tion in the method of disposal may be made only after communication to the Public Works Director and receipt of a letter of approval as in the first instance. Section 11. A person installing or operating water-treating apparatus of the kind described in Section 9 shall make such apparatus accessible to the Public Works Director for inspection, and shall make such reports as the Public Works Director may request as to the operation of the apparatus. Section 12. Any water treating apparatus which has a rated capacity less than five gallons in an 8-hour period shall be exempt from the provi- sions of this article. Multiple units installed to supply water to the same points of use shall be considered as a single apparatus for the purposes of this section. Section 13. Nothing in this Article shall be construed as lessening the applicability of other requirements of this Article. ARTICLE V Special Restrictions - Industrial Waste Waters Section 14. Any person desiring to discharge industrial waste water -6- into a public sewer in Redlands in an amount exceeding 100 gallons in one day shall submit a letter to the Public Works Director presenting informa- tion as to the kind and size of the industrial operations producing the waste water , the quantity and characteristics of the waste water , detailed plans for any pretreatment facilities planned to prevent discharge of improper materials to the sewer , and any other information requested by the Public Works Director . If the Public Works Director finds, (1) that the quality of the water and the existing facilities or facilities for which the person furnishes a commitment to install within a reasonable period for discharge to the sewer , conform to the requirements of this and other ordinance of the City, (2) that any existing or committed pretreatment facilities are adequate, and (3) that the sewer capacity is available, he shall reply approving the discharge of that waste water to the sewer. A letter of approval shall state (1) the nature of the industry and the nature and amount of flow which the applicant may discharge to the sewer , ( 2) shall include any restrictions which the Public Works Director finds necessary in order that the sewerage system may serve its intended purpose, and (3) in the event that installation or pretreatment or other facilities are 'deemed necessary, shall specify the period of time granted for the installation of pretreatment or other facilities . If the Public Works Director finds that the proposed discharge will not be lawful under this Article or other applicable laws he shall so notify the applicant. I Section 15. If the discharger wishes to make alterations of pretreat- ment facilities or alterations of connections to the sewer , or if he wishes to discharge additional waste or to discharge wastes in excess of the amounts which have been approved, or -wastes of a different kind, he shall submit to the Public Works Director a letter .requesting approval of such alteration. The Public Works Director shall treat this in the same manner as an original application under Section 14. Section 16. It shall be unlawful , after one hundred eighty (180) days from March 1 , 1966, for any person to discharge into the public sewerage system of the City of Redlands , directly or indirectly, any industrial waste water in excess of 100 gallons a day which is not approved as to kind and amount by a letter from the Public Works Director . Any such discharge shall be in, accordance with any restrictions and conditions imposed in the Public Works Director ' s letter of approval, except that the Public Works Director shall grant such reasonable extensions of time in excess of the one hundred eighty (180) day period as may be necessary for plant alterations , changes in process or the design, acquisition, manufactun--, installation and testing of the committed treatment or other facilities which additional time the Public Works Director agrees is required to effect compliance. Section 17. Except as hereinafter set forth, no industrial waste shall be discharged to a public sewer unless it conforms to the requirements set forth in this Article for all discharges to public sewers , and no industrial waste water flow exceeding 100 gallons in any one day shall be discharged to a public, sewer unless it conforms also to the requirements set forth in this section. Compliance with the requirements of this section shall be based on the mean values obtained from analysis of representative industrial waste samples collected not more often than once a day over a one month period at the point of entry of the industrial waste to the public sewer system or if this is not feasible at other points up the stream. Such up-stream samples shall be weighted with the flow at the sampling point to -furnish weighted values of all required chemical constituents. Wherever deemed practical by the Public Works Director these industrial waste water samples may be composited, and the analysis> made from such composite sample. (a) The content of dissolved solids shall at no time exceed the yearly average dissolved solids in the ,water supply plus 1000 milligrams per liter. (b) The content of sodium-ion shall at no time exceed the yearly average sodium-ion in the water plus 200 milligrams per liter. (c) The content of chloride-ion shall at no time exceed the yearly average of chloride-ion in the water supply plus 200 milligrams per liter. (d) The content of sulphate shall at no time exceed the yearly average sulphate in the water supply plus 100 milligrams per liter. (e) The content of boron shall at no time exceed the yearly average boron in the water supply plus 1.0 milligrams per liter of boron. (f) The content of fluoride shall at no time exceed the yearly average of fluoride in the water supply plus 1 .0 milligrams per liter of fluoride. (g) The content of hardness expressed as calcium carbonate shall not exceed the monthly average hardness in the water supply plus 100 milligrams per liter . (h) The content of total oil and grease shall at no time exceed 600 milligrams per liter . (i) The content of floatable oil and grease shall at no time exceed 100 milligrams per liter . ( j) The content of floatable hydro-carbon oil shall at no time exceed 100 milligrams per liter . (k) The standard 5-day biochemical oxygen demand shall at no time exceed 1000 milligrams per liter . ( 1) The suspended solids content shall at no time exceed 1000 milligrams per liter. (m) The dissolved sulfide content shall at no time exceed 0. 1 milligrams per liter. (n) Toxic constituents shall at no time exceed the values prescribed by Regional Water Quality Control Board No. 8 in its Resolutions 57-1 which are as follows : Arsenic 0. 10 mg/l Barium 2.0 mg/l ad :um 0.02 mg/l Cyanide 0.4 mg/l Hexavalent Chromium 0. 10 mg/1 Lead 0. 10 mg/l Selenium 0.02 mg/l Silver 0. 10 mg/l, (o) The pH shall at no time be below 6. Section 18. The 'point of determining compliance with the provisions of this article shall be the point of discharge to the public sewerage system or such other upstream sampling point as may have been agreed to by the Public Works Director. The Public Works shall specify procedures for obtaining necessary samples and the Public Works Director may require that any persons discharging industrial waste water through the sewer install a measuring device and that the samples be analyzed and measurements of flow be taken and reported to the City and such sampling and measuring device shall be made accessible to the Public Works Director or his author- ized representative. Where certain wastes are critical as to the operation of the sewerage system the Public Works Director may require installation of recording or other measuring equipment and the obtaining of samples at selected points within the industrial operation prior to the point of discharge to the public sewerage system, with submission of records and sample analysis to the City. The Public Works Director may require that the industry provide for the inspec'tion and testing of quality of the waste water or performance of waste water pretreatment facilities by an impartial. third party with reports to the City. The Public Works Director may require that a permittee report to the City from time to time on the amount of materials processed by the industry or other information which he finds necessary to evaluate the effect of the wastes on the sewerage system. Section 19. Every letter of approval for discharge of industrial waste waters shall be considered tentative, and the approval shall be revoked by, the Public Works Director when it is found that the discharge which the letter approves is in fact in violation of this Article or of other laws or regulations of the City, or that the information furnished by application in applying for the approval was misleading or that the discharge is causing harm, nuisance , or unreasonable burden in operation of the sewerage system. Section 20. Nothing in this Article shall be construed as lessening the applicability of other requirements of this Article. ARTICLE VI Waivers Section 21. If any discharge to a public sewer contains or may contain constituents which will cause it to fail to conform to any of the require- ments set forth hereinbefore in Articles IV and V but the Public Works Director finds that ( 1) the discharge will not cause harm to the sewerage system nor unreasonably or inequitably burden the operation of the system and (2) when considered together with similar excesses in discharges of others limited by Articles IV and V, will not materially effect the ability of the City to meet the requirements of the Regional Water Quality Control Board on the City' s sewage effluent discharge, he shall grant approval for discharge to the sewer with waiver or modification of the requirement which would not be met. A commercial establishment having as its principal business the regeneration of water softening equipment shall be permitted by the Public Works Director to discharge up to 201 by weight of the regenerating chemicals to the sewer , if this is done during the flushing and rinsing cycle of his operations and not during the brine cycle. To make use of this provision the establishment must provide the Public Works Director with monthly notarized records of the weight of all regeneration chemicals purchased and the weight of all such chemicals used in regenera- tion, and the Public Works Director must be satisfied that controls are so established that discharge of the chemicals to the sewer will be limited as provided above. In his letter of approval he shall include a statement regarding the requirement that it is waived with reasons as to why the waiver is reasonable. A copy of this letter shall be filed with the City Clerk. Any waiver granted pursuant to this section shall be subject to withdrawal at any time the Public Works Director makes a subsequent finding that the City sewerage system is burdened or the ability of the City to meet Regional requirements is materially affected. ARTICLE VII General Provisions Section 22. It shall be unlawful for any person to discharge or cause to be discharged into any storm drain or storm water channel or natural water course, whether currently carrying water or not, or into any pipe or waterway leading to such drain, channel, or watercourse, any solid or fluid material which will impair the useful functioning of such drain, channel , or watercourse, or which will cause expense to the City, or other public agency, in maintaining the proper functioning of same, or which will cause public nuisance or public hazard or which will cause detrimental pollution of natural surface of subsurface waters . Section 23. It shall be unlawful for any person to deposit or dis- charge or cause to be deposited or discharged into any sump which is not impermeable or into any pit or well , or on to the ground, or into any storm drain or watercourse any material which by seeping underground or by being leached or by reacting with the soil is detrimental to the usable underground waters and exceeds the range of the effects of ordinary non- _10- industrial land uses on underground waters into which such wastes may seep, or which will violate any requirements of Water Quality Control Board No. 8. Section 24. Decisions , judgment or findings made by the Public Works Director pursuant to this ordinance may be appealed to the City Council. The City Council may amend, modify, confirm or reject any such decision, judgment or finding (including waivers) provided the purpose and intent of this ordinance is not violated. No appeal shall be made with respect to the specific ordinance requirements pertaining to quality, content or type of disposal of waste water that may be discharged, as contained in Section 17 Articles II and III, and the 20% limit on regeneration chemicals discharged to the sewer as set forth in Article VI. Section 25. Any person, firm or corporation violating any of the pro- visions of this Ordinance shall be guilty of a misdemeanor , and upon con- viction thereof shall be punishable by a fine of not more than Three Hundred Dollars ( $300.00) or by imprisonment for a period of not more than three (3) months , or by both such fine and imprisonment. Each such person, firm or corporation shall be deemed guilty of a separate offense for every day during any portion of which any violation of any provisions of this ordinance is committed, continued or permitted by such person, firm or corporation, and shall be punishable therefor , by such firm, person or corporation, and shall be punishable therefor as provided by this Ordinance. Section 26. The invalidity of any article, section, clause, sentence, or provisions of this Ordinance shall not affect the validity of any other part which can be given effect without such invalid part or parts. Section 27. Wherever in this Article time limits are established or periods of compliance or extensions thereof are specified the commencement date for computing such periods or time limits for areas annexed to the City of Redlands subsequent to enactment of this Article shall be the official annexation date. This section shall have no application to firms or industries established subsequent to the annexation date. ARTICLE VIII Ordinance in Force Section 28. This ordinance shall be in full force and effect , when in the opinion of the City Council the majority of the private and public agencies within the counties of San Bernardino and Riverside which construct, operate and maintain sewerage systems making discharges into the Santa Ana River Basin have adopted similar regulations in accordance with the require- ments of the Water Quality Control Board.
