(A) General conditions. The following described substances, materials, waters or wastes shall be limited in discharges to the JSA sewer system to concentration or quantities which: will not harm either the sewers, wastewater treatment process or equipment; will maintain and protect water quality in the receiving stream; and will not otherwise endanger lives, limb, public property or constitute a nuisance. The Executive Director or his or her designee may set additional limitations or limitations more stringent than those established in the provisions below if in his or her opinion more severe limitations are necessary to meet the above objectives, in forming his or her opinion as to the acceptability of a discharge, the Executive Director or his or her designee shall give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment plant, and other pertinent factors.
(B) Restricted discharges.
(1) Any garbage that has not been properly shredded. Garbage grinders may be connected to sanitary sewers from homes, motels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers;
(2) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants which: injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, causes the JSA to violate the terms of its KPDES permit, prevents the use of acceptable sludge disposal methods, or exceed a limitation set forth in a categorical pretreatment standard;
(3) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the JSA in compliance with applicable state or federal regulations;
(4) Any water or wastes which by interaction with other water or wastes in the public sewer system, release noxious gases, form suspended solids that interfere with the collection system, or create a condition deleterious to structures and treatment processes;
(5) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed to the extent required by the JSA’s KPDES permit;
(6) Wastes or waters classified as a hazardous waste by the Resource Conservation and Recovery Act (RCRA) without a minimum 60-day prior written notification of such discharge to the Executive Director. Such written notification must include the name of the hazardous waste, the EPA hazardous waste number, type of discharge, volume/mass of discharge and time of occurrence). The Executive Director or his or her designee may prohibit or condition the discharge at any time;
(7) Wastewater identified as causing, along or in conjunction with other sources, the POTW treatment plant effluent to fail a toxicity test;
(8) Any portion of human or animal anatomy;
(9) Any wastes containing detergents, surface active agents or other substances which will cause excessive foaming in the JSA’s sewer system;
(10) Any water or wastes which have characteristics based on a 24-hour composite sample, grab or a shorter period composite sample, if more representative, that exceed the following normal maximum domestic wastewater parameter concentrations:
Parameter Maximum | Allowable Concentration Without Surcharges |
BOD | 300 ppm |
TSS | 350 ppm |
NH3-N | 25 ppm |
Oil and grease (total) | 100 ppm |
Any person discharging wastewater exceeding the maximum allowable concentration as noted above, will be subject to a surcharge fee for each pound of loading over and above the set limit. Any other amenable constituents requiring the addition of specific chemicals for proper treatment will also be subject to surcharge as noted on the discharge permit exceeding the effluent limits specified above shall not be deemed to constitute a violation of a permit condition or this subchapter if the appropriate surcharge fee is paid and the discharge does not cause interference or pass through of the POTW. | |
(11) The following limitations are established for characteristics of any wastewaters to be discharged into the JSA’s sewer system. All significant industrial users must comply with these limitations where they are more stringent than applicable state and/or federal regulations.
Parameter | Maximum Daily Concentration |
Parameter | Maximum Daily Concentration |
Arsenic | 0.30 ppm |
Cadmium | 008 ppm |
Chloride | 10,000 ppm |
Chromium, total | 0.70 ppm |
Chromium, hexavalent | 0.39 ppm |
Copper | 1.06 ppm |
Cyanide | 0.39 ppm |
Lead | 0.14 ppm |
Mercury | 0.02 ppm |
Nickel | 1.90 ppm |
pH | 6 - 9 units |
Selenium | 0.10 ppm |
Silver | 0.53 ppm |
Tetrachloroethylene | 0.27 ppm |
Zinc | 1.70 ppm |
(12) The JSA has received authority through the U.S. EPA and state statutes to enforce the requirements of 40 C.F.R. subchapter N, 40 C.F.R. part 403, and 40 C.F.R. part 35. Accordingly, in addition to the requirements set forth above, all users shall comply with the requirements of those regulations.
(C) Dilution of wastewater discharge. No user shall ever increase the use of process water or, in any way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the categorical pretreatment standards, or in any pollutant specific limitation developed by the JSA or the state.
(D) Protection from accidental and slug discharges.
(1) Each significant industrial user shall provide protection from accidental and/or slug discharges of prohibited materials or other substances regulated by this subchapter. Facilities to prevent accidental and/or slug discharges of prohibited materials shall be provided and maintained at the owner or user’s own cost and expense. At any time, the JSA may require each industrial user to develop or update a plan to control slug discharges. If the JSA determines that a slug control plan or revision is necessary, the plan shall contain the following:
(a) Description of discharge practices;
(b) Description of stored chemicals;
(c) Procedures for notifying the POTW; and
(d) Prevention procedures for spills.
(2) In the case of all actual accidental and/or slug discharges, the user shall immediately telephone to notify the JSA of the incident In any event, said telephone notification shall be followed by a written confirmation no later than two hours after the accidental and/or slug discharge. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions.
(3) Within five days following an accidental and/or slug discharge, the user shall submit to the Executive Director or his or her designee a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, fish kills or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties or other liability applicable under this subchapter or other applicable law.
(4) A notice shall be permanently posted on the user’s bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who may cause or suffer from such a dangerous discharge are advised of the emergency notification procedure.
(E) 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 in this subchapter.
(F) JSA’s right of revision. The JSA reserves the right to establish more stringent limitations, or requirements on discharges to the POTW if deemed necessary to comply with the objectives presented in this subchapter.
(G) Categorical pretreatment standards. Upon the promulgation of categorical pretreatment standards for a particular industrial subcategory, the standard, if more stringent than limitations imposed under this subchapter for sources in that subcategory, shall immediately and automatically supersede the limitations imposed under this subchapter.
