§ 90-126. Prohibitions and limitations of discharge.

(a)

Generally. Users shall not discharge pollutants into the WWF unless in accordance with this article.

(b)

Discharge prohibitions. No user shall discharge into the WWF any waste or wastewater which may cause pass through or interfere with the operation or performance of the WWF. No user shall discharge into the WWF or any connected system any waste or wastewater containing any of the following:

(1)

Toxic or poisonous substances, chemical elements or compounds, taste or odor-producing substances, or any other substances which are not amenable to treatment or reduction by the wastewater treatment processes employed by the ECRWWTF. Toxic pollutants shall include, but not be limited to, any pollutant identified pursuant to 40 CFR 116(4).

(2)

Noxious, or malodorous solids, liquids, or gases or other wastewater which, either singly, or by interaction with other waste or wastewater:

a.

Are capable of creating public nuisance or hazard to human or animal life;

b.

Are or may be sufficient to prevent entry into a sewer for its maintenance, inspection, or repair; or

c.

May create any hazard in the receiving waters of the ECRWWTF.

(3)

Pollutants which create a fire or explosion hazard in the WWF. Prohibited materials include, but are not limited to, petroleum oil and non-biodegradable cutting oil, gasoline, kerosene, fuel oil, motor oil, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, and sulfides or any other substance which the city, the state, or any federal agency has determined is a fire hazard or a hazard to the WWF.

(4)

Radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by regulations within the Florida Administrative Code issued by the state department of health, and which will or may cause damage or hazards to the WWF or its operating personnel.

(5)

Stormwater, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool discharges, uncontaminated cooling water, unpolluted industrial process waters, air conditioning condensate, unless specifically authorized by the city in writing.

(6)

Domestic wastes from septic tanks, portable toilets, or other similar facilities, unless specifically authorized by the city in writing. Such discharges shall only be made at a site approved by the city.

(7)

Mineral oil in excess of 50 mg/L or animal/vegetable fats, wax, grease, or oils in excess of 100 mg/L, whether emulsified or not; or substances which may solidify or become viscous at temperatures lower than or equal to 150 degrees Fahrenheit (65.56 degrees Celsius).

(8)

All trucked or hauled pollutants are prohibited except at discharge points designated by the city.

(9)

Inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residues) or dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate) in such concentrations as to pass through or cause interference with the operations of the WWF.

(10)

Waste or wastewater having a pH lower than 5.5 s.u. exhibiting any corrosive property which either singly or by interaction with other wastes is capable of causing damage or hazard to structures, processes, equipment, or personnel of the WWF.

(11)

Waste or wastewater having a pH higher than 9.5 s.u. which either singly or by interaction with other wastes is capable of causing damage or hazard to structures, processes, equipment or personnel of the WWF.

(12)

BOD, COD, or chlorine in such concentration and/or flow as to constitute a significant load on or shock to the ECRWWTF or cause interference.

(13)

Volume of flow or concentrations of wastes constituting slugs as defined in this article.

(14)

Liquid or vapor having a temperature higher than 150 degrees Fahrenheit (65.56 degrees Celsius) or that causes influent temperature to the ECRWWTF to exceed 104 degrees Fahrenheit (40 degrees Celsius), except where higher temperatures are approved by DEP.

(15)

Solid or viscous substances in such quantities or of such size as to be capable of causing obstruction to the flow in a sewer, or other interference with the proper operation of any connected system, such as but not limited to: particles greater than one-half inch in any dimension, grease, un-comminuted food wastes, animal entrails or tissues, paunch manure, bones, hair, hides or fleshings, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains or hops, waste paper, wood plastics, rubber stoppers, tar asphalt residues from refining or processing of fuel or lubricating oil, gasoline, naphtha, and similar substances either whole or ground.

(16)

Excessive discoloration which cannot be removed by the treatment process, such as but not limited to dye, printing wastes, and vegetable tanning solutions which imparts color to the ECRWWTF effluent thereby violating the city's NPDES permit. The discoloration (in combination with turbidity) shall not cause the ECRWWTF effluent to reduce the depth of the compensation point for photosynthetic activity by more than ten percent from the seasonally established norm for aquatic life.

(17)

Medical wastes, except as authorized by the city in a wastewater discharge permit.

(18)

Detergents, surface-active agents, or other substances which may cause excessive foaming in the WWF.

(19)

Any sludges, screenings, or other residuals from the pretreatment of industrial wastes.

(20)

Toxic gases, vapors, or fumes in a quantity that may cause acute worker health and safety problems.

(c)

Compliance with national and local standards. It shall be unlawful for any person to discharge any pollutant into the WWF or a connected system except when such discharge is in compliance with federal standards promulgated pursuant to the act, and any other more stringent state and local standards. Wastes containing concentrations in excess of the national categorical pretreatment standards are prohibited.

(d)

Local pretreatment standards.

(1)

No person shall discharge wastewater containing pollutants in excess of the local limits for those pollutants which have been established for East Central Regional Wastewater Treatment Facility using standard procedures, calculations and methods acceptable to FDEP to protect against pass through, interference, protection of WWF employees, and adverse effects on wastewater residual disposals. No industrial user shall discharge process waste streams, unregulated waste streams, or dilute waste streams in excess of the concentrations set forth from time to time by resolution of the city commission. Local limits shall be included as permit conditions and attached to each SIU wastewater permit issued. Any wastes containing concentrations in excess of the local pretreatment standards—surcharge limit shall be subject to surcharge, in accordance with section 90-133 of this Code.

(2)

Local limits are subject to change and shall be modified as needed based on regulatory requirements and standards, WWF operation, performance and processes, the industrial user base, potable water quality and domestic wastewater characteristics. Modifications to the established local limits must be reviewed and approved by FDEP prior to implementation. Implementation shall be effective 30 days from notice of acceptance of the modified limits by FDEP. Permitted SIUs shall also be issued an addendum to their wastewater discharge permit containing the new local limits. The local limits apply at the point where the wastewater is discharged to the WWF.

(3

All concentrations for metallic substances are for total metal unless indicated otherwise. The city may impose mass limitations, instantaneous maximum limitations, maximum monthly average values, or maximum four-day average values, in addition to, or in place of, the limitations listed above. The city may also develop best management practices (BMPs) to implement local limits. Such BMPs shall be considered local limits and pretreatment standards for the purpose of this article.

(4)

Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the city's authorized representative may impose equivalent concentration or mass limits in accordance with Rule 62-625.410(4), F.A.C.

(5)

When the limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the city may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual Industrial users. This should be in accordance with Rule 62-625.410(4), F.A.C.

(6)

When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the city's authorized representative shall impose an alternate limit using the combined waste stream in accordance with Rule 62-625.410(6), F.A.C.

(7)

A user may obtain a variance from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in Rule 62-625.700, F.A.C., that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.

(8)

A user may obtain a net gross adjustment to a categorical pretreatment standard in accordance with Rule 62-625.820, F.A.C.

(e)

Right of revision. The city reserves the right to establish, by ordinance or in wastewater discharge permits, more stringent limitations or requirements on discharges to the WWF if deemed necessary to comply with the requirements of this division.

(f)

Dilution. 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 unless expressly authorized by an applicable federal categorical pretreatment standard, or in any other pollutant-specific limitation developed by the state. The city may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements or in other cases when the imposition of mass limitations is appropriate.

(g)

Septic and industrial waste hauling.

(1)

Septic tank waste may be introduced into the WWF only at the septic receiving station located at the ECRWWTF.

(2)

Any industrial or septic waste haulers shall have a discharge permit issued under conditions specified in section 90-128.

(3)

No hauled load may be discharged without prior written consent from the city. Samples may be collected from each load to ensure compliance with applicable standards. The industrial or septic waste hauler may be required to provide waste analysis of any load prior to discharge.

(4)

Industrial and septic waste haulers must provide a waste tracking form for every load. The form shall include, at a minimum, the name and address of the waste hauler, permit number, truck identification, names and addresses of sources of waste, volume and characteristics of waste. This form shall identify the type of industry known or suspected waste constituents and whether any wastes are RCRA hazardous wastes.

(h)

Control of discharge. If any wastes or wastewaters are discharged, or are proposed to be discharged, to the WWF which contain the substances or possess the characteristics enumerated in this section as prohibited by this article, do not meet applicable pretreatment standards and requirements, and/or which may have a deleterious effect upon the WWF, its processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the city may:

(1)

Reject the wastes or deny or condition the introduction of new sources of wastewater to the WWF; or

(2)

Require the industrial user to demonstrate that in-plant improvements will modify the discharge to such a degree as to be acceptable; and/or

(3)

Require pretreatment of the industrial user's discharge to ensure compliance with this article; and/or

(4)

Require payment of an industrial waste surcharge to cover the added cost of handling and treating excess loads imposed on the WWF by such discharge. Surcharge amounts shall be established by a resolution of the city, together with a schedule of rates and fees of the WWF. Imposition of industrial waste surcharges for the recovery of treatment costs does not replace or supersede the requirements for pretreatment facilities, should they be found necessary by the city.
