(14) Any wastewater containing concentrations of detergents, surface-active agents or other substances which may cause excessive foaming in the POTW.
(15) Any wastewater which is trucked or hauled or from recreational vehicles except at discharge points designated by the authority.
(16) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause Interference or Pass Through.
(17) The use of any additives such as enzymes, surfactants, solvents, emulsifiers, bacteria or chemicals which allow grease to pass from the collection system is prohibited. The use of an additive as a supplement to grease trap maintenance or sewer line maintenance may be authorized by the authority after submission of proper documentation and efficiency review.
(b) Limitation on Wastewater Strength.
(1) National categorical pretreatment standards. National categorical pretreatment standards as promulgated by the U.S. EPA pursuant to the Act shall be met by all dischargers of the regulated industrial categories. An application for modification of the national categorical pretreatment standards may be considered for submittal to the regional administrator by the authority, when the authority's waste- water treatment system achieves consistent removal of the pollutants as defined in 40 CFR § 403.7.
(2) State requirements. State requirements and limitations on discharges to the POTW shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations or those in this subchapter or any other applicable law.
(3) Right of revision. The authority reserves the right to amend this subchapter to provide for more stringent limitations or requirements on discharges to the POTW where deemed necessary to comply with the objectives set forth in Section 935.21.

C. The authority may develop Best Management Practices (BMPs), by ordinance or in individual wastewater discharge permits to implement Local Limits and the requirements of 935.23.
D. Grease, oil, and sand interceptors/traps shall be provided when, in the opinion of the authority, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand. All interception/trap units shall be of a type and capacity approved by the authority, shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected and cleaned, by the discharger at their expense using an oil and grease hauler certified by the City. A copy of the inspection form must be turned into the City within two working days of the inspection and cleaning. All interceptors/trap shall have the components failing inspection repaired within thirty (30) days following the inspection and have the repaired interceptor/trap inspected by the City.
(5) Dilution. No discharger shall increase the use of potable or process water in any way, nor mix separate waste streams for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this subchapter. The authority may impose mass limitations on dischargers which are using dilution to meet the pretreatment standards or requirements of this subchapter, or in other cases where the imposition of mass limitations is deemed appropriate by the authority.
(c) Accidental Discharges/Slug Discharge Control.
(1) Each discharger shall provide protection from accidental discharge of prohibited or regulated materials or substances established by this subchapter. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the discharger's cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the authority for review, and shall be approved by the authority before construction of the facility. Each existing discharger shall complete its plan and submit its plan to the authority by June 1, 1989. No discharger who discharges to the POTW after the aforesaid date shall be permitted to introduce pollutants into the system until accidental discharge protection procedures have been approved by the authority. Review and approval of the plans and operating procedures by the authority shall not relieve the discharger from the responsibility to modify its facility as necessary to meet the requirements of this subchapter.
(2) The authority shall evaluate whether each significant industrial user needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The authority may require any discharger to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. Alternatively, the authority may develop such a plan for any discharger. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
A Description of discharge practices, including non-routine batch discharges;
B. Description of stored chemicals;
C. Procedures for immediately notifying the authority of any accidental or Slug Discharge, as required by 935.23(c)(3) of this ordinance; and

(3) Dischargers shall notify the authority immediately upon the occurrence of a slugload, or accidental discharge of substances prohibited by this subchapter. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. Any discharger who discharges a slugload of prohibited materials shall be liable for any expense, loss, or damage to the POTW, in addition to the amount of any fines imposed on the authority on account thereof under state or federal law.
(4) Reports of Changed Conditions.
Each User must notify Authorized or Duly Authorized Representative of the City of Harrison, Ohio of any significant changes to the User's operations or system which might alter the nature, quality, or volume of its wastewater at least thirty (30) days before the change.
A. Authorized or Duly Authorized Representative of the City of Harrison, Ohio may require the User to submit such information as may be deemed necessary to evaluate the changed conditions, including the submission of a wastewater discharge permit application.
B. Authorized or Duly Authorized Representative of the City of Harrison, Ohio may issue an individual wastewater discharge permit or modify an existing wastewater discharge permit of this ordinance in response to changed conditions or anticipated changed conditions.
(5) Notification of the Discharge of Hazardous Waste. The City of Harrison prohibits the discharge of Harrison's Wastes.
(6) Signs shall be permanently posted in conspicuous places on discharger's premises, advising employees whom to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover such a discharge with respect to emergency notification procedure.
(7) The authority shall evaluate the need for a plan, device or structure to control a potential slug discharge at least once during the term of each significant industrial user's control mechanism or within one year of being identified a significant industrial user.
(d) Bypass. No discharger shall "bypass" or intentionally divert the wastestream from any portion of an industrial user's treatment facility, which would result in a violation of existing pretreatment standards or requirements. Bypasses which are necessary for essential maintenance of facilities may be approved if notice is given to the approval authority at least ten (10) days in advance of a planned bypass. In the event of an unplanned bypass, the industrial user must orally notify the approval authority within 24-hours of the time the bypass is known, and must provide written submission to the authority within five days of the time the industrial user becomes aware of the bypass, describing the cause, duration, and methods of correction. Approval of bypasses may also be made if they were made to prevent the loss of life, personal injury, or severe property damage.
(e) Permits. The Director of Public Works or his/her authorized representative may issue permits to any industrial user designating certain substances as pollutants and appraising user of the applicable pollutants which must be treated by said user and the limits of allowable discharge from user's system. Said limits shall be maximum limits under this subchapter. The Director of Public Works or his/her authorized representative may issue permits to any industrial user to require compliance with any requirements under this pretreatment subchapter including applicable categorical pretreatment standards, other discharge limits, and reporting requirements.
(f) Individual Wastewater Discharge Permit Duration. An individual wastewater discharge permit shall be issued for a specified time period, not to exceed one (1) year from the effective date of the permit. An individual wastewater discharge permit may be issued for a period less than one (1) year, at the discretion of Authorized or Duly Authorized Representative of the City of Harrison, Ohio. Each individual wastewater discharge permit will indicate a specific date upon which it will expire.
(g) Individual Wastewater Discharge Permit Contents.
