4. Any discharge of ammonia nitrogen as N in excess of 40 mg/l shall be subject to surcharge at the rate of $0.511 per pound of ammonia nitrogen. | |||
All surcharges shall be in addition to any other fees or charges required by this chapter. Surcharges are intended to reimburse the POTW for all costs incurred by the POTW in handling or treating a discharge which contains pollutants in excess of specified surcharge concentrations, loadings or other applicable limits. Any user exceeding applicable surcharge limitations or other applicable limits shall be subject to the imposition of one or more surcharges as provided by this section to reimburse the POTW for any costs or expenses, direct or indirect, the POTW may incur in handling or treating the discharge, or which may be imposed upon the POTW, where the exceedence of applicable limits causes or contributes to those costs or expenses. All exceedences of applicable discharge prohibitions and limitations and all instances of noncompliance with applicable discharge requirements shall constitute a violation of this chapter, subject to applicable fines, penalties and other enforcement actions provided by this chapter. In no event shall the imposition of a surcharge for a discharge which does not meet the applicable prohibitions, limitations or requirements be construed as authorizing the illegal discharge or otherwise excuse a violation of this chapter. | |||
† Discharges containing more than one pollutant which may contribute to fume toxicity shall be subject to more restrictive limitations, as determined necessary by the WWTP Superintendent. The more restrictive discharge limits will be calculated based on the additive fume toxicity of all compounds identified or reasonably expected to be present in the discharge, including, without limitation, the specific compounds listed in division (B)(1) of this chapter. | |||
This daily maximum limit for BOD of 1,400 mg/l shall be effective until December 31, 2006. Thereafter, the daily maximum limit for BOD shall decrease by 100 mg/l per year as follows: 1300 mg/l (effective January 1, 2007 through December 31, 2007) and from that date thereafter, unless and until this chapter is subsequently amended as approved by the POTW to provide a different daily maximum limit for BOD) | |||
(2) Pollutants in concentrations that exceed the instantaneous maximum, daily maximum or monthly average concentrations listed below in this subsection:
Parameter | Instantaneous Maximum | Daily Maximum | Monthly Average Concentration |
Mercury | The instantaneous maximum concentration, daily maximum and monthly average discharge limit for mercury is 0.0000026 mg/l. except as otherwise required by the POTW Superintendent, compliance with this limit shall be determined as follows: | ||
A compliance limit of “non-detect” shall be used for instantaneous maximum concentration, daily maximum and monthly average. Any discharge of mercury at or above the detection limit is a specific violation of this chapter. The detection limit shall be established pursuant to the procedure for determination of the method detection limit (MDL) as set forth in §§ 3(a) of Appendix B of 40 C.F.R. part 136. The MDL study used to determine the MDL shall be made available to the POTW immediately upon request. In no case may the detection limit exceed 0.0002 mg/l, unless a higher detection limit is approved by the POTW Superintendent because of sample matrix interference. | |||
Mercury sampling procedures, preservation and handling, and analytical protocol for compliance monitoring of a user's discharge shall be in accordance with EPA method 245.1, unless other sampling procedures, protocol or methods (including, but not limited to, EPA method 1631) are required or approved in advance by the POTW Superintendent. | |||
If determined necessary by the POTW Superintendent to prevent interference or pass through, to protect the POTW, to comply with applicable federal or state laws or regulations, to comply with the POTW's NPDES permit, or to otherwise meet the purposes and objectives of this chapter, any user determined by the POTW Superintendent to have a reasonable potential to discharge mercury to the POTW may be required to develop, submit for approval, and implement a mercury reduction plan (MRP). At a minimum, the MRP shall contain such requirements and conditions (including, but not limited to, requirements and conditions regarding source identification; best management practices; schedules of compliance; monitoring, sampling and analysis; and reporting), as determined necessary by the POTW Superintendent to ensure the mercury reduction efforts will be effective in achieving the goals of this Section. Failure to submit an approvable MRP within the specified deadlines or to comply with any condition or requirement of an approved MRP shall constitute a violation of this chapter, subject to the fine, penalty, and other enforcement provisions of this chapter. | |||
(3) Any liquid, solid, gas or other pollutant which by reason of its nature or quantity is sufficient either alone or by interaction with other substances to create a fire or explosion hazard or be injurious in any other way to persons, the POTW, or to the operation of the sewerage system, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140º F or 60º C using test methods specified in 40 C.F.R. § 261.21. At no time shall two successive readings on an explosion hazard meter at the point of discharge into the POTW (or at any point in the POTW) be more than 5% nor any single reading over 10% of the lower explosive limit (LEL) on the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, fuel, fuel oil, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorate, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the POTW, the State or EPA has notified the user is a fire hazard or a hazard to the system.
(4) Pollutants that may cause corrosive structural damage to the POTW, or that due to their corrosive properties are capable of causing injury to persons or POTW personnel or harm to fish, animals or the environment. Discharges that have a pH lower than 6.5 or greater than 9.5 shall not be discharged.
(5) Any solid, insoluble or viscous substance in concentrations or quantities which may cause obstruction to the flow in the POTW, may create an encumbrance to the POTW operations, or which otherwise may result in interference, including, but not limited to, grease, animal entrails or tissues, bones, hair, hides or fleshings, whole blood, feathers, ashes, cinders, sand, cement, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, strings, fibers, spent grains, spent hops, wastepaper, wood, plastics, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes or tumbling and deburring stones.
(6) Pollutants, including, but not limited to, oxygen demanding pollutants, released at a flow rate and/or pollutant concentration that may cause pass through or interference with the POTW or constitute a slug load. In no case shall a slug load have a flow rate or contain concentrations or qualities of pollutants that exceed for any time period longer than 15 minutes, more than five times the average 24-hour concentration, quantities or flow during normal production.
(7) Wastewater (or vapor) having a temperature that will inhibit biological activity in the POTW resulting in interference, or heat in such quantities that the temperature at the POTW treatment plant exceeds 104º Fahrenheit (40º C).

(8) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin
in amounts that will cause interference or pass through.
(9) Pollutants that result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems. This prohibition includes, but is not limited to, wastewaters which contain liquids, solids or gases that cause gases, vapors or fumes from the discharge to exceed 10% of the immediately dangerous to life and health (IDLH) concentration. Discharges which contain more than one pollutant which may contribute to fume toxicity shall be subject to more restrictive limitations, as determined necessary by the WWTP Superintendent. The more restrictive discharge limits shall be calculated based on the additive fume toxicity of all compounds identified or reasonably expected to be present in the discharge.
(10) Trucked or hauled pollutants, except those discharged at the WWTP at the discharge point designated by the WWTP Superintendent, subject to the prior approval of the Superintendent and issuance of a wastewater discharge permit.
(a) The WWTP Superintendent shall determine whether to allow the discharge of trucked or hauled pollutants based on the particular nature or quantity of the proposed discharge in accordance with the discharge prohibitions, limitations and requirements provided by this division.
(b) The WWTP Superintendent may impose any conditions on the discharge determined necessary to ensure compliance with this division, including, without limitation, conditions regarding the time, place, and manner of discharge, restrictions on the quantity and quality of the discharge, and sampling requirements.
(c) The discharge shall not commence without prior notice to, and authorization from, the WWTP Superintendent, and a representative of the POTW shall be present at all times during the discharge.
(d) All trucked or hauled wastes to be discharged to the POTW must be accompanied by a completed waste manifest form signed by the permittee and the hauler as provided by the minimum requirements of this section. The permittee shall certify in writing on the manifest as to the source of all wastes in the load proposed to be discharged and that the wastes have been pretreated as required by applicable pretreatment standards and requirements. The hauler shall certify in writing on the manifest that no wastes other than those listed on the manifest have been accepted by the hauler. The manifest must be reviewed by the WWTP Superintendent prior to commencing discharge of the load. Failure to accurately record every load, falsification of data, or failure to transmit the form to the WWTP Superintendent for review prior to discharge shall constitute a violation of the permit and may result in revocation of the permit and/or the imposition of fines and penalties as provided by this chapter.
(e) The permittee's discharge of hauled wastes shall be subject to sampling by the POTW at any time, including, without limitation, prior to and during discharge. The WWTP Superintendent may require the permittee to refrain from, or suspend, discharging until the sample analysis is complete.
(f) Trucked or hauled pollutants will be accepted only if transported to the POTW in compliance with state and federal hazardous waste and liquid industrial waste laws.
(g) For each discharge of trucked or hauled pollutants, the permittee will be required to pay to the POTW a trucked or hauled pollutant discharge fee to cover the POTW's administrative expenses and any additional treatment, handling or inspection expenses incurred by the POTW in connection with the discharge. The fee shall be established, paid, and collected as provided by §§ 53.295 to 53.299. This discharge fee shall be in addition to any sewer rates, fees, charges, or surcharges otherwise required by this chapter.
(11) Solvent extractibles, including, but not limited to, oil, grease, wax, or fat, whether emulsified or not, in excess of applicable local limits; or other substances that may solidify or become viscous (with a viscosity of 110% of water) at temperatures between 32º Fahrenheit and 150º Fahrenheit in amounts that may cause obstruction to the flow in sewers or other interference with the operation of the POTW.
