A connection permit, for which a charge of $25.00 will be made by the Oakland County Department of Public Works, shall be obtained from the Department of Public Works before such connection is made. Prior to the issuance of such connection permit, the person obtaining such permit shall have obtained the written approval of the local unit of government. Connection shall be made in a workmanlike manner and in accordance with methods and procedures established by the Department of Public Works. The party to whom such a permit is issued shall be responsible for notifying the Department of Public Works 24 hours in advance of the date and time when such a connection is made so that proper inspec- tion of same can be made by the department. (T) Prior to the adjustment, reconstruction, relocation or any other altering of the sewers of the County of Oakland including manhole structures, the Contractor or the person responsible for the work shall first obtain a permit to do such work from the Oakland County Department of Public Works. Said permit fee shall be determined by the Department of Public Works. (B) IT-1 12-1-82 (E) Prior to construction and during the life of permits obtained in accordance with Paragraphs 1(1), 1(C) and 1(0) of these general regulations, all owners or contractors shall: (1) yearly funaish . to the Oakland County Department of Public Works a satisfactory surety bond in the amount of five thousand dollars ($5,000.00) as security for the faithful performance of the work in accordance with the plans and specifications and Departmental Standards, and (2) yearly furnish to the Oakland County Department of Public Works a cash deposit in the amount of five hundred dollars ($500.00). Such deposit shall provide funds for emergency work and/or such other work as may be deemed necessary by the Oakland County Department of Public Works, arising as a result of construction by the owner or contractor. Such bonds shall not be cancelled by the owner, the contractor or the surety without first having given ten (10) days written notice to the Oakland County Department of Public Works. Cash deposits may be returned to the owner or contractor within ten (10) days of receipt of written request therefore, except that no deposits will be returned until such time as all outstanding permits have received final inspection and approval. In the event that it becomes necessary for the Oakland County Department of Public Works to expend funds for work arising as a result of Con- . struction by the owner or the contractor, then the cost of such work shall be deducted from the aforementioned cash deposit. The owner or contractor shall have the right and opportunity to correct any deficiencies promptly before any deposit funds will be spent by the Oakland County Department of Public Works. The owner or contractor shall, within thirty (30) days of the mailing of written notice thereof, pay to the Oakland County Department of Public 1.nerkz the entire amount of such cost. Failure to comply with these rules and regulations and the standards of the Oakland County Department of Public Works nay result in the immediate termin- ation of the surety and cash bonds. 2. Bulkhead The contractor shall install a suitable bulkhead to prevent construction water, sand, silt, etc. from entering the existing sewer system. Such bulkhead shall be left in place until such time as removal is authorized by the Oakland County Department of Public Works. 3. Acceptance Test All sanitary sewer systems shall be subjected to infiltration, air, or exfi/tration tests or a combination thereof in accordance with the following requirements prior to acceptance of the system by the Oakland County Depart- ment of Public Works and prior to removal of the bulkhead as required in Paragraph (2). All final acceptance tests shall be witnessed by the Oakland County Depart- ment of Public Works. (A) Infiltration Test All sewers over 24" diameter shall be subjected to infiltration testa. All sewers of 24" diameter or smaller where the ground water level above the top of the sewer is over 7 feet shall be subjected to an infiltration test. Maximum allowable infiltration shall not exceed 200 gallons per inch of diameter per mile of pipe per 24 hours for the overall project. (B) Air Test or Exfiltration Test All sewers of 24 inch diameter or less, where the ground water level above the top of the sewer is 7 feet or less shall be sub- jected to air tests or exfiltration tests. For exfiltration tests, the internal water level shall be equal to the external water level plus seven (7) feet as measured from the Lop of pipe. The allowable exfiltration rate shall be the same as that permitted from infiltration. The procedure for air testing of sewers shall be as follows: The sewer line shall be tested in increments between manholes. The line shall be cleaned and plugged at each manhole. Such plugs shall be designed to hold against the test pressure and shall provide an airtight seal. One of the plugs shall have an orifice through which air can be introduced into the sewer. An air supply line shall be connected to the orifice. The air supply line shall he fitted with suitable control valves and a pressure gauge for continually measuring the air pressure in the sewer. The pressure gat0;-e. shall have a minimum diameter of 3-1/2 inches and a range of 0-10 ?SIG. The gauge shall have minimum division of 0-10 ?SIG and an accuracy of 0.04 ?SIG. The sewer shall be pressurized to 4 ?SIC greater than the greatest back pressure caused by ground water over the top of the sewer pipe. At least 2 minutes shall be allowed for the air pressure to stabilize between 3.5 and 4 PSIG. If necessary, air shall he added to the sewer to maintain a pressure of 3.5 MG or greater. After the stabilization period, the air supply control valve shall be closed so that no more air will enter the sewer. The sewer air pressure shall be noted and Liming for the test begun. The .test shall not begin if the air pressure is less than 3.5 ?SIG, or such other pressure as is necessary to compensate for ground water level. The time required for the air pressure to decrease 1.0 PSIG during the test shall not he less than the time shown in the "Oakland County Department of Public Works Air Test Tables". Manholes on sewers to be subjected to air tests shall be equipped with a 1/2 inch diameter galvanized capped pipe nipple extending through the manhole, 37 into the manhole wall and at an -elevation equal to the Lop of the sewer pipe. Prior to the air test the ground water elevation shall be determined by blowing air through the pipe nipple to clear it and then connecting a. clear plastic tube to the pipe nipple. The tube shall be suspended vertically In the manhole and the ground water elevation determined by observing the water level in the tube. The air test pressure shall be adjusted to com- pensate for the maximum ground water level above the top of the sewer pipe to be tested. After all tests are performed and the sewer is ready for final acceptance, the pipe nipple shall be plug- ged in an acceptable manner. If a sewer fails to pass any of the previously described tests, the contractor shall determine the location of the leaks, repair them and retest the sewer. The tests shall be repeated until satisfactory results are obtained. All visible leaks and cracks shall be repaired regardless of test results. 4. Storm and Ground Water Control (A) Yard drains, patio drains, catchbasins, downspouts, weep tile, perimeter and footing drains or any other structure used for the collection and conveyance of storm water and/or ground water shall_ not be 'permitted to discharge into any sanitary sewer connected directly or indirectly to the County System, except as provided under Paragraph 4(B).

B. All measurements, teats, and analyses of the characteristics of waters and wastes to which reference is made in this regulation shall be determined in accordance with the current edition of "Standard Methods for the Examination of Water and Wastewater", published by the American Public Health Association. C. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the wastewater facilities and to determine the existence of hazards to life, limb, and pro- perty. The County Agency will determine the method of sampling to be used. 4. Restrictions A. If any waters or wastes are discharged, or are proposed to be dis- eh-organ!, to the palic sewers, which waters contain the substances, possess the characteristics, or exceed the limitations enumerated elsewhere, the County Agency may 1. Prohibit the discharge of the wastes to a public sewer, or, 2. Temporarily permit the discharge of the wastes to a public sewer to any conditions that the County Agency and the City may recommend based on their review of such factors as quantity of the waste in relation to flows and velocities in the sewers, materials of construction of sewers, nature of the wastewater treatment process, capacity of the waste- water treatment works, degree of treatability of the waste, and any other pertinent factors, or, 3. Require pretreatment to an acceptable condition for discharge to a public sewer, and/or, 4. Require control over the quantities and rates of discharge to public sewers. 5. Apply a surcharge as described elsewhere in these regulations. IV-2 12-1-82 B. In all cases, the County Agency may require payment to cover any additional costs it may incur in connection with inspecting, sampling, testing, handling and treating the wastes, not covered by existing wastewater charges. 1. When the pretreatment or equalization of waste flows is per- mitted, the design and installation of the plants and equip- ment shall be subject to the requirements of all applicable codes, ordinances and laws. 2. Where preliminary treatment of flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense. r I 12-1-82 ARTICLE DISCHARGE OF INDUSTRIAL OR COMMERCIAL WASTE INTO THE PUBLIC SEWERS The regulations contained in this Article are generally intended to protect the public health and safety through the regulation and control of the quantity and quality of industrial and commercial waste admitted into the public waste- water treatment system and to enable the municipalities contracting with the County of Oakland for sewage disposal and the County of Oakland to comply with the requirements of applicable State and Federal Laws, including the Federal Water Pollution Control Act of 1972 (Public Law 92-500), as amended, and the State of Michigan, Act 245 of 1929, as amended, and the applicable National Pollutants Discharge Elimination System Permits, and by Federal Environmental Protection Agency General Pretreatment Regulations (40 CFR 403). 1. PROHIBITIONS A. Prohibited Pollutants - It shall be unlawful for any person to cause or allow to be discharged sewage or wastes of any kind or indirectly into the wastewater system which does not conform to the criteria or effluent standards set forth in "Appendix A" to this Regulation. The user shall be permitted to demonstrate to the County of Oakland that the influent being recetved by the user contains pollutants and upon such demonstration, the user shall be accountable only for the net pollutants added to the effluent and not for the total pollutants contained in the effluent. The user shall not be liable for noncom- pliance due to an upset condition. B. Measuring Methods - In order to ascertain whether or not the sewage or waste of any kind discharged by any person into the public sewers or wastevater system conforms to the criteria or effluent standards established and adopted by this Regulation, the County may use any appropriate method or device which will lead to such a determination. All measurements, tests and analyses of wastewater, sewage and wastes of any kind shall be determined in accordance with standard methods. C. When required by the County, each person covered by this Regulation shall provide a control manhole or any other device or fac- ility suitable and appropriate to enable the County to conduct gauging and sampling operations to determine conformance with the criteria and effluent standards established and adopted by this Regulation. The gauging and sampling facility should normally be situated on the user's premises, but the County may, when such a location would be impractical or cause undue hardship on the user, allow the facility to be constructed in the public street or sidewalk area and it shall be the responsibility of the user to obtain any necessary approvals for the location of the gauging and sampling facility from appropriate governmental agencies. V-1 12-1-82 V-2 4/85 The County shall have the right, during reasonable hours and, at the option of the user, accompanied by a representative of the user, to enter upon the premises of each person for the purpose of setting up measurement or sampling devices or facilities, or for inspecting or examining the same or for conducting necessary or desirable measuring and sampling operations. The duly authorized employees of the County shall be permitted to enter all properties accompanied by a representative of the user, at the user's option, for the purpose of inspection, observation, measurement, sampling and testing in accordance with the provisions of this Article. Duly authorized employees shall have no authority to inquire into any process, including metallurgical, chemical, oil, refining, ceramic, paper or other industries beyond that point having a direct bearing on the kind and source of discharge to the sewers or waterways or facilities for waste treatment. While performing the necessary work on private properties, authorized employees of the County shall observe all safety, security and other company rules applicable to the premises established by the company. Where requested by the property owner or his agent, such persons shall leave a portion of any sample taken from any sampling point on or ad- jacent to the premises with such property owner or agent. In cases of disputes arising over shared samples, the portion taken and analyzed by the representatives of the County shall be presumed to be the valid sample. D. Federal Categorical Pretreatment Standards - A federal Categorical Pre- treatment Standard for a particular industrial sub-category, if more stringent than criteria imposed under this Regulation for sources in that sub-category_or if not covered by this Regulation shall supercede the criteria imposed under this Regulation upon the date compliance is required by the Federal Standard, The County shall notify all affected users of the applicable requirements under 4ocrR 403.12. E. Modifications - The County may modify the effluent limitations appli- cable to indirect dischargers as specified in the Federal Pretreatment Standards if the requirements contained in 40 CFR 403.7 are fulfilled concerning consistent removal of pollutants by the publicly owned treat- ment works, and prior approval from the owner of the POTW and from the approval authority (MDNR or EPA) is obtained. F. State Requirements - State requirements and limitations on discharges shall apply in any case where they are more stringent than Federal requirements and limitations or those imposed under this Regulation effective upon the dates compliance is required thereby. G. City Right of Revision Each City reserves the right to establish by ordinance more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in Article V of this Ordinance. Individual permits may specify more stringent requirements or limitations than chose set forth in this ordinance when, in the opinion of the County such requirements or limi- tations are necessary to prevent interference with the operation or performance of the POTW. H. Dilution Prohibited - Dilution of a waste discharge introduced into the wastewater system by an increase in the use of process water as a continuing practice in partial or complete substitution for adequate treatment is not acceptable as a method for achieving the criteria set forth in the Regulation or the limitations contained in the Federal Pretreatment Standards. I. Any introduction of any wastewater or industrial waste which origi- nates outside the service area of the Cities of Walled Lake and Novi is expressly prohibited unless permission for such introduction is obtained from the County in advance. 2. FEES A. Purpose - It is the purpose of this Section to provide for the re- covery of costs from users of the public wastewater system for the implementation of the program established herein. The applicable charges or fees shall be as set forth in the Schedule of Charges and Fees, adopted by the County from time to time, and shall be sufficient to meet costs of operation of the system or as provided by law. Furthermore, user fees and surcharges as required by law shall be adopted by the County on the basis of the volume of waste and the quantities of specific pollutants present in the wastewater. 3, REPORTING REQUIREMENTS The County of Oakland, through the County Agency, may require all users to submit periodic reports on waste discharge volume, quality, specific pollutant analyses, and any other information pertaining to the provisions of this Regu- lation.

VARIANCE/SPECIAL ARRANGEMENTS 1. Variances From Interim Standards - The County may grant variances from any of the effluent criteria or standards set forth in Appen- dix "A" to this Regulation or the effective date of such criteria or standards. In determining whether to grant a variance, the County shall consider the following factors, one or more of which may be sufficient for the granting of a variance. A. Age, size, land availability, and configuration as they relate to the user's equipment or facilities, processes employed, and engineering aspects of control and treatment technology. B. Energy requirements of the application of the required control and treatment technology. C. •Aspects of the user's process which affect the nature or quality of the pollutants or pollutant parameters contained in the raw-waste loads in the user's process water or effluent or which affect the volume of the user's process water or effluent. D. Cost of compliance with such interim criteria or standards, but only if it is caused by one or more of the above listed factors. E. The absence, at the date of the request for variance, of an applicable Federal Pretreatment Standard for that industrial category covering the specific pollutant for which the variance is requested, or the existence of a less stringent Federal Pre- treatment Standard for that pollutant. 7. Unavailability of adequate pollution control equipment. 2. Request - Requests for a variance and supporting evidence must be submitted in writing to the County. Pending the County's decision on a variance request the interim effluent criteria and standards imposed by this Regulation shell be effective. Written submissions for variance requests must include: A. The name and address of the user making the request; A. Identification of the interest of the requester which is affected by the interim standard for which the variance is requested; C. A list of each pollutant or pollutant parameter for which an alternative discharge limit is sought; D. The alternative discharge limits proposed by the requested for each pollutant or pollutant parameter identified in Item "C"; E. A description of the user's existing water pollution control facilities including schematic flow plans of the user's water supply, wastewater process systems and discharge points; and F. A statement of facts clearly establishing why the variance request should be approved, including detailed support data, documentation, and evidence necessary to evaluate the merits of the request. 3. Terms and Conditions of Granted Variance - At the County'e dis- cretion, the variance may be made retroactive to the date of application. Variances shall be for a specified length of time and shall set forth recommended alternative discharge limits for the user's discharge as follows: In the case of pollutants listed in Parageaph 2 of Appendix "A" to this Regulation, recommended alter- native discharge limits shall be imposed to the extent warranted by the factors demonstrated to the County. V-10 4/85 4. Disposition/Revocation - The County, after receiving a submittal from a requester, will issue a finding within 30 days. Where the County finds that reasonable grounds for a variance do not exist, he may deny the request and notify the requester in writing of the denial giving the reasons for its decision. Where the County finds reasonable grounds to exist for granting the variance request, it shall approve the request and prepare the recommended terms and conditions for notice to the requester. Within 30 days following the date of receipt of notice of the County's denial or conditioning of the variance, if granted, the requested may petition the County for a hearing to reconsider or contest the decision. If the County determines that the following conditions exist, they shall constitute grounds for a revocation of an existing variance after notice and opportunity for hearing before the County: A. That user discharges under the terms and conditions of the variance would result in the wastewater treatment plant being in violation of its NPDES Permit and/or effluent standards. B. That user discharges under the terms and conditions of the variance result in violation of the General Prohibitions enumerated in Paragraph 1 of Appendix "A" to this Regulation. Noncompliance with the terms and conditions of the variance. 5_ Special Arrangements - Nothing in the Regulation shall be construed as preventing any special agreement or arrangement between the County, and any user whereby wastewater of unusual strength or character is accepted into the POTW and treatment subject to any payments or user charges as may be applicable, however, no federal prohibited discharge standards can be waived. SAVINGS CLAUSE If any provision, paragraph, word, section or article of this Regulation is invalidated by any court of competent jurisdiction, the remaining provision, paragraphs, works, sections, and articles shall not be affected and shall con- tinue in full force and effect. CONFLICT All other Regulations and parts of other Regulations inconsistent with or conflicting with any part of this Regulation are hereby repealed to the extent of such inconsistency or conflict.
