Okaloosa County BOCC — August 2, 2016 — proposed Water & Sewer Ordinance (tracked changes version) — reading text

24-236. - Federal standards applicable; reporting requirements. Upon the promulgation of the Federal Categorical Pretreatment Standards for a particular industrial subcategory, the federal standard, if more stringent from limitations imposed under this article for sources in that subcategory, shall immediately supersede the limitations imposed under this article. The Board shall notify all affected users of the applicable reporting requirements under applicable federal, state, or board regulations. When wastewater subject to a categorical Pretreatment Standard is mixed with wastewater not regulated by the same Standard, the Director shall impose an alternate limit in accordance with 40 CFR 403.6(e). Sec. 24-237. - Local discharge limits No person shall discharge wastewater containing pollutants, in excess of the local limits for those pollutants, which have been established for Okaloosa County Water and Sewer’s wastewater treatment facilities using standard procedures, calculations and methods acceptable to the Florida Department of Environmental Protection to protect against pass through, interference, protection of facility employees, and adverse effects on wastewater treatment residuals disposal. No industrial user shall discharge process waste streams, unregulated waste streams, or dilute waste streams in excess of the concentrations set forth by the Director. Local limits shall be included as permit conditions and attached to each Significant Industrial User wastewater permit issued. The established local limits apply at the point where the wastewater is discharged to the County’s POTW. All concentrations for metallic substances are for total metal unless indicated otherwise. At his or her discretion, the Director may impose mass limitations in addition to or in place of the concentration based limitations. A copy of the approved local limits is available upon request to the Water and Sewer Director1804 Lewis Turner Blvd. Suite 300 Fort Walton Beach, Florida 32547 or by telephone at (850) 651-7172.

For the enforcement of the above provisions any person, firm, corporation or other legal entity discharging industrial waters or industrial sewage into the system in violation of the provisions of this article shall pay a penalty listed in Appendix A for each violation, and in addition to such minimum penalty shall pay the rates provided for herein plus a penalty of 50 percent of the sewer consumption rates as specified in Appendix A and the measure of the volume discharge into the sewer system shall be based upon the average sewage produced by such person, corporation or entity over a 30-day period. The Board may, at its discretion, in addition to such penalty charges, disconnect the water service and the sewer service of such person, or both. Sec. 24-239. - Interceptors. Grease, oil, and sand interceptors shall be provided when, in the opinion of the Board, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, sand, or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Board and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors the Owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates, and means of disposal which are subject to review by the Board. Any removal and hauling of the collected materials not performed by Owner's personnel must be performed by currently licensed waste disposal firms. Sec. 24-240. - Pretreatment or flow-equalizing facilities. Where pretreatment or flow-equalizing facilities are provided or required for any waters or sewage, they shall be maintained continuously in satisfactory and effective operation by the Owners at their expense. Sec. 24-241. - Significant industrial or commercial users. Any industry or commercial establishment discharging into the sewer system more than 25,000 gallons per day or any discharger so designated as a Significant Industrial or Commercial User by the Board shall comply with the following: (1) In order to provide for accurate sampling and measurement of industrial sewage, each designated User shall provide and maintain, on each of its industrial sewage outlet sewers, a large manhole or sampling chamber to be located outside or near its facility boundary line. If inside the facility fence, there shall be a gate near the sampling chamber with a key furnished to the Board. There shall be ample room provided in each sampling chamber to enable convenient inspection and sampling by the Board, or its authorized agent. (2) Each sampling chamber shall contain a parshall flume, accurate weir, or similar device, with a recording and totalizing register for measurement of the liquid quantity; or the metered water supply to the industrial facility may be used as the liquid quantity where it is substantiated that the metered water supply and sewage quantities are approximately the same, or where a measurable adjustment can be made in the metered supply to determine the liquid quantity. The measuring, totalizing, recording devices are to be supplied, installed, and maintained by the Owner of the facility. (3) Samples shall be taken every hour, properly refrigerated and composited in proportion to the sewage flow for a representative 24-hour sample. Such sampling shall be repeated on as many days as necessary to insure representative quantities for the entire reporting period. Industrial facilities with wide fluctuations in quantities of sewage will require an automatic sampler paced automatically by the flow-measuring device. Minimum requirements for representative quantities shall include reevaluation during each quarterly period. The determination of representative quantities shall include not less than three consecutive days of 24-hour composite samplings of sewage flow taken during periods of normal operation, together with acceptable flow Page 48 of 118  measurements. The frequency of sampling, sampling chamber, metering device, sampling methods, and analysis of samples shall be subject, at any time, to inspection and verification by the Board. Sampling and measuring facilities shall be such as to provide safe access for authorized personnel of the Board for making such inspection and verification. Plans for sampling location shown on a site plan shall be submitted to the Board for approval. (4) The Owner of each facility discharging industrial sewage shall submit monthly to the Board, on forms supplied by the Board, a certified statement of the quantities of its sewage discharged into the sewers and wastewater treatment works of the Board or into any sewer connected therewith. Copies of pertinent water bills shall be submitted with the above statement. Such documents shall be filed with the Board not later than the tenth day of the following month. A separate statement shall be filed for each industrial or commercial facility. The total quantities of sewage to be measured and certified by the Owner shall be: (1) liquid in gallons, (2) five-day BOD in pounds, (3) suspended solids in pounds, on a dry solids basis, (4) total phosphorus in pounds, (5) total Kjeldahl nitrogen in pounds, (6) COD in pounds, and (7) pH. Sec. 24-242. - Discharge of sewage into storm sewer prohibited. No person shall discharge or cause to be discharged any sewage into the storm sewer system without exception. Sec. 24-243. - Permit required for discharge of cooling and/or condensing water. Cooling and/or condensing water may be discharged to the sanitary sewer system only if a permit is obtained from the Board. Sec. 24-244. - Compliance requirements. The Industrial or Commercial Users may be required to provide information needed to determine compliance with this article. These requirements may include: (1) Sewage discharge peak rate and volume over a specified time period. (2) Chemical analysis of sewage. (3) Information on raw materials, processes, and products affecting sewage volume and quality. (4) Quantity and disposition of specific liquid, sludge, oil, solvent, or other materials important to sewer use control. (5) A plot plan of sewers on the user's property showing sewer and (if required) pretreatment facility location. (6) Details of sewage pretreatment facilities (if required). (7) Details of systems to prevent and control the losses of materials through spills to the Board's sewer. The Director may request an Industrial or Commercial User to complete a questionnaire that addresses those items listed above. Sec. 24-245. - Industrial charges and regulations. All charges for collecting, receiving, transporting and treating industrial sewage and industrial wastewaters shall be subject to negotiation. The amount charged will include all expenses incurred by the Board in handling and treating such sewage or waste and shall include any cost of chlorinating the same when mixed with the sewage. Page 49 of 118 All of such service must be approved and the terms and conditions fixed under the provisions of a written contract. All industrial sewage or industrial wastewaters discharged into the system under agreement with the Board where the BOD does not exceed 300 milligrams per liter (mg/l), where the fats do not exceed 100 mg/l and where the suspended solids do not exceed 200 mg/l shall be handled by the Board on the aforementioned sewer rates. Additional charges listed below shall be made when the BOD, the fats and the suspended solids exceed these amounts. For all sewage having a BOD in excess of 300 mg/l and up to and including 1,000 mg/l, there shall be an additional charge as specified in Appendix A for such excess. Where the BOD is in excess of 1,000 mg/l, there shall be a charge as specified in Appendix A for such additional excess. For all sewage containing fats in excess of 100 mg/l and up to and including 200 mg/l, there shall be an additional charge as specified in Appendix A for such excess and for sewage containing fats in excess of 200 mg/l, there shall be a charge as specified in Appendix A for such additional excess. For all sewage containing suspended solids in excess of 200 mg/l, including those suspended solids outlined in section 24-235 above and up to and including 800 mg/l there shall be a charge as specified in Appendix A for such excess and for all sewage containing in excess of 800 mg/l the charge shall be as specified in Appendix A for such additional excess. For all sewage with a temperature in excess of 100 degrees F shall be charged $0.10 for a degree hour per 1,000 gallons based on average temperature and water used per week. All industrial or commercial sewage before being discharged into the sewer system of the Board shall be metered and no sewage shall be discharged until so metered. All cost of the meter shall be borne by the Applicant. Appropriate devices or access areas shall be installed and maintained for the purpose of sampling such sewage and the Board shall have the free and continued access over the property of the User for the purpose of sampling the sewage to determine the amount of BOD, fats and suspended solids, to determine the pH, and to determine the temperature of the sewage so as to fix the amount of additional charges which are to be made as provided herein. The Board may take such samples at any time or any place as determined by the Board. In the event excess BOD or fats continue to be discharged after warning from the Board, the Board may elect to discontinue the service on 24 hours' notice
