(H) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving stream of the POTW;
(I) (1) Any water or waste which has characteristics based on a 24-hour composite sample, grab or a shorter period composite sample if more representative, which exceed the following normal maximum domestic wastewater parameter concentrations:
Parameter | Daily Maximum Allowable Concentration Without Surcharge |

NH-N | 30 mg/l |
TSS | 250 mg/l |
(2) Discharges greater than these concentrations may be subject to penalties contained in the Enforcement Response Plan for the city in addition to surcharge.
(J) The city has received authority through U.S. EPA and state statutes to enforce the requirements of 40 C.F.R. subpart N and 40 C.F.R. part 403. All users shall comply with the requirements of those regulations as well as with all sections of this chapter;

(2) This notification must include the name of the waste, EPA hazardous waste number, type of discharge, volume/mass of discharge and time of occurrence. The Superintendent may deny or condition this discharge at any time; and
(L) The following limitations are established for characteristics of any wastewaters to be discharged into the municipal sewer system.

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 federal categorical pretreatment standards, or for any other pollutant-specific limitation developed by the city or the commonwealth.
(Ord. 634, passed 3-5-2002)
Grease, oil and sand interceptors shall be provided when in the opinion of the Superintendent they are necessary for the proper handling of liquid wastes containing floatable oils and/or greases in excessive amounts, or any flammable wastes, 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 Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner(s) 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. The city may require reporting of such information for their review. Any removal and hauling of the collected materials not performed by the owner’s personnel must be performed by currently licensed waste disposal firms. Interceptors shall also comply with applicable regulations of the county’s Health Department.

(A) Pursuant to the requirements imposed on publicly-owned wastewater treatment works by the Federal Water Pollution Control Act Amendments of 1972, being 33 U.S.C. §§ 1251 et seq., and later amendments, all pretreatment standards promulgated by the U.S. EPA under 40 C.F.R. subpart N and 40 C.F.R. part 403 for new and existing industrial discharges to public sewer systems are hereby made a part of this chapter. Any industrial waste discharge which violates these EPA pretreatment standards shall be in violation of this chapter.
(B) Where pretreatment or flow equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s) at his or her expense.
(C) Any person who transports septic tank contents, seepage pit or cesspool contents, liquid industrial waste or other batch liquid waste and wishes to discharge such waste to the public sewer system shall first obtain permission for such discharge from the Superintendent. All persons receiving such permission shall abide by all applicable provisions of this chapter and any other special provisions that may be established by the Superintendent as necessary for the proper operation and maintenance of the sewerage system. Waste haulers who have been granted permission to discharge to the public sewer system shall pay fees for such discharge in accordance with a fee schedule established by the Superintendent and approved by the city. It shall be illegal to discharge any batch liquid waste into any manhole or other part of the public sewer system, or any building sewer or other facility that discharges to the public sewer system, except at points of discharge designated by the Superintendent for such purposes. Any liquid waste hauler illegally discharging to the public sewer system shall be subject to immediate revocation of discharge privileges (if granted) and further subject to the penalties and enforcement actions prescribed in § 52.999 of this code. Nothing in this chapter shall relieve waste haulers of the responsibility for compliance with the county’s Health Department, state or federal regulations.

(A) (1) Each significant industrial user shall provide protection from accidental and/or slug discharges of prohibited materials or other substances regulated by this chapter. Facilities to prevent accidental and slug discharges of prohibited materials shall be provided and maintained at the owner or user’s own cost and expense. Once every two years, the Superintendent will determine whether each significant industrial user needs to develop a plan to control slug discharges.
(2) If the Superintendent decides that a slug control plan is needed, 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.
(3) In the case of all possible or actual accidental and/or slug discharges, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include the location of discharge, type of waste, concentration and volume and corrective actions taken.
(B) Within five days following an accidental and/or slug discharge, the user shall submit to the Superintendent 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 which may be imposed by this subchapter, the Enforcement Response Plan or other applicable law or regulation.
(C) 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 such dangerous discharges to occur are advised of the emergency notification procedures.
(Ord. 634, passed 3-5-2002)
The city reserves the right to establish, by a majority vote of its commissioners, more stringent limitations or requirements on discharges to the POTW at the recommendation of the Superintendent or if deemed necessary to comply with the objectives presented in this chapter.
