§ 78-132. Prohibitions and limitations on discharge into the POTW.

(a)

General prohibitions. No user shall introduce, or cause to be introduced, into the POTW any pollutant or wastewater which causes pass through or interference. These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements.

(b)

Specific prohibitions. No user shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:

(1)

Any liquids, solids or gases which because of their nature or quantity are or may be sufficient, either alone or by interaction with other substances, to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW, including, but not limited to, wastestreams with a closed-cup flashpoint of less than 140 degrees F. (60 degrees C.) using the test methods specified in 40 CFR 261.21. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system or at any point in the system, be more than five percent or any single reading over ten percent of the lower explosive limit (LEL) of the meter. Prohibited materials include but are not limited to gasoline, kerosene, fuel oil, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides or any other substances which the city, the state or any federal agency has determined or may determine to be a fire hazard or a hazard to the systems.

(2)

Any wastewaters or waste having a pH less than 5.0 (or more than 9.5), or any liquids, solids, or gases having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the POTW.

(3)

Solids or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the treatment works such as but not limited to grease, ashes, cinders, grass clippings, sand, mud, straw, shavings, metal, glass, rags, wastepaper, feathers, tar, asphalt residues, gas, fuel or lubricating oil, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, bones, entrails, paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.

(4)

Pollutants, including oxygen-demanding pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause Interference with the POTW; or any materials that may exert or cause:

a.

Inert suspended solids, such as but not limited to Fuller's earth, lime slurries and lime residues, or of dissolved solids, such as but not limited to sodium chloride and sodium sulfate.

b.

BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment works.

c.

Volumes of flow or concentration of wastes constituting slug discharges, as defined in this article.

(5)

Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, as defined in this article, but in no case may heated wastewater be discharged in such quantities that the temperature at the treatment works influent exceeds 40 degrees Celsius (104 degrees Fahrenheit). Unless a higher temperature is allowed in the user's wastewater discharge permit, no user shall discharge into any sewer line or other appurtenance of the POTW wastewater with a temperature exceeding 65.5 degrees Celsius (150 degrees Fahrenheit).

(6)

Petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in excess of 100 mg/l or parts per million.

(7)

Pollutants which 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.

(8)

Any trucked or hauled pollutants except those lawfully discharged at specific points designated by the assistant to the city manager for public services.

(9)

Noxious or malodorous liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair.

(10)

Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent, thereby violating the city's NPDES permit.

(11)

Wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the assistant to the city manager for public services in compliance with applicable state or federal regulations.

(12)

Stormwater, surface water, ground water, artesian well water, roof runoff, subsurface drainage, uncontaminated cooling water, swimming pool backwash or drainage, condensate, deionized water, noncontact cooling water, and unpolluted industrial process wastewater, unless specifically authorized by the assistant to the city manager for public services.

(13)

Sludges, screenings, or other residues from the pretreatment of industrial wastes.

(14)

Medical wastes in concentrations that will violate any of the objectives of this SUO, or as specifically authorized by the assistant to the city manager for public services in an IWDP.

(15)

Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail any toxicity test or to violate its NPDES or FDEP waste discharge permit or the receiving water quality standards.

(16)

Detergents, surface-active agents, or other substances which that might cause excessive foaming in the POTW.

(17)

Any water or waste containing fats, wax, grease or oils of animal or vegetable origin, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32 and 150 degrees Fahrenheit (zero and 65 degrees Celsius).

(18)

Any substance which may cause the POTW's effluent or any other product of the POTW, such as residues, sludges, or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program. In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act, or state criteria applicable to the sludge management method being used.

(19)

Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the assistant to the city manager for public services or building inspector.

(20)

Any waters or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits which may be established by the assistant to the city manager for public services, as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters.

(21)

Any discharges containing compounds that are labeled for the control of pest species of any type, such as, but not limited to, acaricides, bactericides, fungicides, herbicides, insecticides, molluscicides, nematicides and rodenticides.

(c)

(d)

Stormwater. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the assistant to the city manager for public services of public works. Industrial cooling water or unpolluted process waters may be discharged, on approval of the assistant to the city manager for public services, to a storm sewer or natural outlet.

(e)

Local limits. No person shall discharge wastewater containing pollutants in excess of the local limits for those pollutants which have been established for the City of Winter Garden's POTW using standard procedures, calculations and methods acceptable to FDEP to protect against pass through, interference, protection of POTW employees, and adverse affects on wastewater residuals disposal. No industrial user shall discharge process waste streams, unregulated waste streams, or dilute waste streams in excess of the concentrations set forth by the assistant to the city manager for public services. Local limits shall be included as permit conditions and attached to each SIU wastewater permit issued.

The established local limits are subject to change and shall be modified as needed based on regulatory requirements and standards, POTW 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 established local limits apply at the point where the wastewater is discharged from the SIU's lateral sewer into the city's sewer (end of pipe). All concentrations for metallic substances are for total metal unless indicated otherwise. At his or her discretion, the assistant to the city manager for public services may impose mass limitations in addition to or in place of the concentration-based limitations.

A copy of the approved local limits is adopted by reference in this article and is available upon request at the following location.

City of Winter Garden
Assistant to the City Manager for Public Services
300 W Plant Street
Winter Garden, FL 34787.

The assistant to the city manager for public services may develop best management practices (BMPs), by ordinance or in IWDPs to implement local limits and the requirements of section 78-132 of this article. Such BMPs shall be considered local limits and pretreatment standards for the purposes of this article.

(f)

Dilution. Unless expressly authorized by an applicable pretreatment standard or requirement, 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 a pretreatment standard or requirement. The assistant to the city manager for public services may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements or in other cases where the imposition of mass limitations is appropriate pursuant to 40 CFR 403.6(c) or Rule 62-625.410(4), F.A.C.

(g)

Duty to comply. Industrial users shall observe and comply with any and all federal, regional, state and local laws, rules, regulations, requirements, ordinances, orders, mandatory guidelines and procedures which apply or pertain to the collection, treatment and disposal of wastewater.

(h)

National Categorical Pretreatment Standards. The National Categorical Pretreatment Standards found at 40 CFR chapter I, subchapter N, parts 405-471 and Chapter 62-660, F.A.C., are incorporated by reference herein. Certain industrial users are or shall become (as determined by the state pursuant to Rule 62-625.410(2)(d), F.A.C.) subject to national categorical standards promulgated by the environmental protection agency. The national categorical standards specify quantities or concentrations of pollutants or pollutant properties which may be discharged into the POTW. All industrial users subject to a national pretreatment standard shall comply with all requirements of such standard, which includes any monitoring or reporting requirements, and shall also comply with any additional or more stringent limitations contained in this article. Compliance with national pretreatment standards for existing sources subject to such standards or for existing sources which become subject to such standards shall be within three years following promulgation of the standards unless a shorter compliance time is specified in the standard or required by the city. Compliance with national pretreatment standards for new sources shall be required upon promulgation of the standard. Except where expressly authorized by an applicable national pretreatment standard, no industrial user shall increase the use of process water or in any way attempt to dilute a discharge as a partial or complete substitution for adequate treatment to achieve compliance with such standard and other pretreatment standards and requirements, including but not limited to more stringent local limits developed under 40 CFR 403.5(c), as it may be amended.

(i)

State pretreatment standards. State requirements and limitations on discharges shall apply when they are more stringent than federal requirements and limitations or those in this article.

(j)

City's right of revisions. The city reserves the right to establish by ordinance, ordinance revision, or through permit conditions more stringent local limitations, requirements, or time periods on discharges to the wastewater disposal system if deemed necessary to comply with the objectives stated for this article. The revision to discharge limitations in this article or in individual permits will be initiated by the assistant to the city manager for public services when necessary. Affected parties will be duly notified and will have the opportunity to comment on the revisions prior to their adoption or incorporation. However, all affected parties are assumed to know and to comply with all state and federal rules, requirements, and guidelines including but not limited to the development, promulgation, and application of local limits; the appropriate use or inapplicability of combined waste stream formulas; and all industrial user and POTW monitoring and reporting requirements.
