Section 11-62-23.1 - Specific requirements for wastewater treatment works(a) In addition to the requirements of section 11-62-08(b), the following documents shall be submitted to the director prior to approval to construct the treatment works:(1) A written declaration signed and dated by the engineer that the proposed treatment works was designed to meet all applicable effluent requirements of sections 11-62-26 and 11-62-27; and(2) Certification by the owner of a proposed treatment works that the treatment works shall be operated and maintained in accordance with all of the provisions of the operation and maintenance manual developed pursuant to subsection (d)(2). The owner shall certify that the operation and maintenance manual shall be available to the operator of the treatment works and shall further certify that, upon sale or transfer of ownership of the treatment works, the sale or transfer will include construction drawings, equipment manuals, operational data collected, and the appropriate transfer documents and provisions binding the new owner to the operation and maintenance manual.(b) All treatment works shall be provided with a continuous effluent flow measuring device such that daily wastewater flow can be determined. For treatment works with design flows equal to or greater than 100,000 gallons per day, the continuous effluent flow measuring device shall include recording equipment to totalize or chart daily flows.(c) Unless otherwise specified by the director, the following distance requirements apply to all treatment works:(1) Treatment units, except as provided in paragraph (3), shall not be less than twenty-five feet from any property lines nor less than ten feet from any building and swimming pools;(2) Disposal systems, excluding effluent irrigation systems, shall not be less than five feet from a property line nor less than five feet from any building; and(3) Completely enclosed, locked, and ventilated equipment rooms used to house items such as blowers, motors, pumps, electrical controls, and chemical feeders shall not be less than five feet from property lines or less than ten feet from dwelling unit(s).(d) No person shall operate a treatment works unless the following documents are provided: (1) A written declaration signed and dated by the engineer responsible for the preparation of the operation and maintenance manual for the treatment works, that the operation and maintenance manual meets paragraph (2) and that if the treatment works is operated in accordance with the manual, all applicable effluent requirements will be met; and(2) An operation and maintenance manual prepared by the engineer. The manual as a minimum, shall provide the details on the following:(A) Operation and maintenance instructions for each pump station and treatment unit or process under normal and emergency conditions such as power outage and equipment malfunction;(B) Operation and maintenance instructions for the disposal system including procedures for purging or chemical 'shock loading" to prevent or eliminate biological growth in the subsurface disposal system;(C) List of required sampling frequencies and analyses to be conducted by the operator;(D) Troubleshooting, corrective, and preventive measures to be taken to maintain process control and treatment performance;(F) Applicable state effluent requirements;(G) Instructions on wasting and disposal of wastewater sludge;(H) Manpower requirements needed to operate and maintain the treatment works;(I) List of critical parts of the treatment works;(J) "As-built" drawings of the treatment works;(K) List of required daily activities checks, and observations; (L) Logs or report forms for all operation and maintenance activities performed;(M) Flow schematic diagrams with details of piping and valving;(N) Plot plan of the treatment works and Project site including all collection lines and equipment;(O) Details on all safety equipment at the treatment works site, any applicable spare parts, maintenance, and operation instructions; and (P) Details on all monitoring equipment including spare parts, maintenance, and operating instructions.(e) No person shall operate a treatment works until it has been inspected to the director's satisfaction and the director has authorized in writing the use of the treatment works. (1) The owner's engineer shall inspect the treatment works and submit to the director a final inspection report stating whether the wastewater treatment works has been constructed according to the submitted plans approved by the director and identifying any discrepancies and their resolutions. Any discrepancy between the constructed treatment works and the approved plans is sufficient reason to withhold approval to operate the treatment works.(2) Before operation of the treatment works, the owner shall resolve all discrepancies.(3) Any changes to the approved plan shall be resubmitted to the director for approval before the final inspection.(4) The inspection shall not be considered final until the constructed treatment works conforms to the approved plans.(f) After the first year of operation, the owner's engineer shall submit to the director a written statement based on results of actual sampling and professional judgment of whether or not the treatment works is meeting and at the design flow will meet the applicable effluent requirements of sections 11-62-26 and 11-62-27. If the treatment works is not meeting the applicable effluent requirements, the owner's engineer shall submit to the director a corrective action report containing: (1) An analysis of the cause of the treatment works' failure to meet the effluent requirements and an estimate of the scope of the corrective action necessary to enable the treatment works to be in compliance;(2) A schedule for undertaking the corrective actions; and(3) A date by which the treatment works shall be in compliance with the applicable effluent requirements.(g) Treatment works shall be designed with safety in mind and comply with appropriate provisions of the Occupational Safety and Health Standards of the State of Hawaii, Department of Labor and Industrial Relations.(h) Upon abandoning, retiring, or permanently discontinuing use of a treatment works, the owner shall render it safe by removing it or filling it completely with earth, sand, gravel, or similar nonorganic matter. All above ground portions of the treatment works shall be rendered safe and vector free. Electrical components shall be disconnected at the circuit breaker or source and all access openings sealed. Injection wells shall be abandoned in accordance with chapter 11-23.(i) For public wastewater treatment works, a facility plan shall be initiated when the actual wastewater flow reaches 75 per cent of the design capacity of the wastewater treatment works. Implementation of the recommendation of the facility plan shall be initiated when the actual wastewater flow reaches 90 per cent of the design capacity of the wastewater treatment works.(j) The owner or operator shall provide standby power for all lift stations to prevent unauthorized discharges of wastewater during a primary power outage.(k) For all treatment works which produce recycled water, the director shall be guided by the requirements of subchapter 1, other applicable sections of this subchapter, and the Reuse Guidelines for all decisions on production of recycled water.
