No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.
A. 
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designed as combined sewers or storm sewers or to a natural outlet approved by the DPW Director and/or the Superintendent.
[Amended 6-16-2008ATM by Art. 26]
B. 
Industrial cooling water or unpolluted process waters may be discharged, on approval of the Superintendent, to a storm sewer, combined sewer or natural outlet.
[Amended 6-16-2008ATM by Art. 26]
No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
A. 
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas. Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to, waste streams with a closed cup flashpoint of less than 140° F. or 60° C. using the test methods specified in 40 CFR 261.21.
B. 
Any waters or wastes containing any pollutant as solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant.
C. 
Any waters or wastes having a pH lower than 5.5 Standard Units (SU) or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
D. 
Solid 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 sewage works, such as but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, and entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
E. 
Any pollutant including oxygen-demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW.
F. 
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
[Amended 6-16-2008ATM by Art. 26]
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely, in the opinion of the Superintendent, that such wastes can harm either the sewers, sewage treatment process or equipment having an adverse effect on the receiving stream, can otherwise endanger life, limb, public property or can constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant and other pertinent factors. In no case will a federally mandated prohibition be altered to be less stringent. The substances prohibited are:
A. 
Any liquid or vapor having a temperature higher than 150° F., 65° C., or, alone or in conjunction with other discharges, that causes the POTW influent to exceed a temperature higher than 104° F., 40° C.
B. 
Any water or waste containing fats, wax, grease, oils, petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, whether emulsified or not, in excess of 100 milligrams per liter or containing substances which may solidify or become viscous at temperatures between 32° and 150° F., 0° and 65° C.
C. 
Any garbage that has not been property shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower, 0.76 hp metric, or greater shall be subject to the review and approval of the Superintendent.
D. 
Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions, whether neutralized or not.
E. 
Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances or wastes exerting an excessive chlorine requirement to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.
F. 
Any waters or wastes containing phenols or other taste- or odor-producing substances in such concentrations exceeding limits which may be established by the Superintendent 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.
G. 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations.
H. 
Any waters or wastes having a pH in excess of 9.5 Standard Units (SU).
I. 
Materials which exert or cause:
(1) 
Unusual concentrations of 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.
(2) 
Excessive discoloration, such as but not limited to dye wastes and vegetable tanning solutions.
(3) 
Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(4) 
Unusual volume of flow or concentration of wastes constituting slugs as defined in this chapter. The POTW has the authority to require any significant industrial user to develop a slug control plan which outlines discharge practices (including nonroutine batch discharges); describes stored chemicals; and contains procedures both to notify the POTW immediately of slug discharges and to prevent adverse impacts from accidental spills (such as operation and maintenance (O & M), general housekeeping, or training).
J. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters. A water or waste may not introduce into the POTW any pollutants which cause pass through or interference.
A. 
If any waters or wastes are discharged or are proposed to be discharged to the public sewers which contain the substances or possess the characteristics enumerated in § 93-20 and which in the judgment of the Superintendent may have a deleterious effect upon the sewage works, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
(1) 
Reject the wastes.
(2) 
Require pretreatment to an acceptable condition for discharge to the public sewers.
(3) 
Require control over the quantities and rates of discharge.
(4) 
Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of § 93-26.
B. 
If the Superintendent permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Superintendent and be subject to the requirements of all applicable codes, provisions of this chapter or other bylaws of the Town.
C. 
The Superintendent may immediately halt or prevent any discharge of pollutants to a public sewer that reasonably appears to present an imminent endangerment to the health or welfare of persons or any such discharge presenting (or which may present) an endangerment to the environment or which threatens to interfere with operation of the Town's wastewater works. Actions which may be taken by the Superintendent include, but are not limited to, seeking ex parte temporary injunctive relief, entry on private property to halt such discharge, blockage of a public sewer to halt such discharge, or demand of specific action by the discharger.
D. 
The Superintendent may seek injunctive relief to enforce the terms of an industrial discharge permit or this chapter.
E. 
The Superintendent may establish pollutant discharge concentrations or mass loadings as necessary to protect the sewage works as well as to ensure compliance with federal, state and local regulations.
F. 
The Superintendent shall notify industries that are subject to § 93-27 of applicable federal, state and local pretreatment regulations, including but not limited to pollutant discharge limitations, compliance deadlines and any revisions to such regulations.
[Amended 6-16-2008ATM by Art. 26]
Grease, oil and sand interceptors shall be provided when, in the opinion of the DPW Director and/or Superintendent, they are necessary for the proper handling of liquid wastes containing grease 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 DPW Director and/or Superintendent and shall be located so as to be readily and easily accessible for cleaning and inspection.
When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole, together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safety located and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
[Amended 6-16-2008ATM by Art. 26]
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the methods and procedures in 40 CFR Part 136, and shall be determined at the control manhole provided or upon suitable samples taken at such control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analyses involved will determine whether a twenty-four-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composites of all outfalls, whereas pH's are determined from periodic grab samples.
A. 
No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the Town and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Town for treatment, subject to payment therefor by the industrial concern.
B. 
In no case will a special agreement waive an IU's responsibility for achieving and maintaining compliance with applicable categorical standards, local limits, or federally prohibited discharge standards.
[Amended 6-16-2008ATM by Art. 26]
C. 
Any agreement with an industrial concern shall require local limits that once adopted are considered pretreatment standards and are federally enforceable. Local limits may not be waived.
[Added 6-16-2008ATM by Art. 26]
[Amended 6-16-2008 ATM by Art. 26]
A. 
All persons discharging wastewater into a public sewer shall comply with federal and state industrial pretreatment regulations (as amended). Industries shall comply with federal and state general pretreatment standards and with the national categorical standards, found in 40 CFR Chapter 1, Subchapter N, Parts 405-471, hereby incorporated into this bylaw. Compliance with such standards shall be achieved no later than the date such standard is effective, unless a shorter compliance time is specified by the Superintendent.
B. 
The Superintendent shall have the right to take independent samples and analyze the discharges of industries connected to a public sewer and shall conduct surveillance and general inspection activities to identify, independent of information supplied by such persons, occasional and continuing noncompliance with this chapter (as amended). Such activities may be conducted without prior notice and need not be confined to normal business hours.
C. 
Significant industrial users shall apply for an industrial discharge permit. Such application shall be made by completing a form developed by the Superintendent. In the case of industrial users identified as significant under 40 CFR 403.3(t), the POTW must issue control through a permit containing at a minimum the following six conditions:
(1) 
A statement of duration.
(2) 
A statement of nontransferability.
(3) 
Applicable federal, state and local effluent limits
(4) 
Self-monitoring, sampling, reporting, notification and recordkeeping requirements.
(5) 
A statement of applicable civil and criminal penalties.
(6) 
Requirements to control slug discharges, if determined by the Superintendent to be necessary.
No significant industrial user may discharge wastewater to a public sewer without an industrial discharge permit duly issued by the Superintendent.
D. 
The terms of an industrial discharge permit may be modified by the Superintendent and a reasonable time provided for compliance with such modified terms. Violations of the terms of such permits are violations of this chapter. Where a conflict exists between the terms of a duly issued permit and this chapter, the permit shall govern. However, under no circumstances can federal and state regulations be waived. Permits may be issued for a maximum period of three years and may not be transferred to a new owner or occupant of the premises without the Superintendent's written approval. A permit may be revoked by the Superintendent if its terms are not met. All industrial users, whether permitted or not, must notify the POTW prior to changing their discharge.
E. 
All new significant industrial users proposing to discharge wastewater to a public sewer shall apply for an industrial user discharge permit at least 60 calendar days before connecting to the public sewer. As part of such application, the Superintendent may require the applicant to obtain written certification from the appropriate federal and state regulatory agencies as to whether the applicant falls within particular industrial categories or subcategories for purposes of industrial pretreatment standards.
F. 
Within 90 calendar days after adoption by a federal or state regulatory agency of a pretreatment standard, existing industries subject to such standards shall submit an application to amend the industrial discharge permit. This application for an amendment shall contain information required under applicable federal and state industrial pretreatment reporting regulations in the form required by the Superintendent. (Such a permit amendment application is in addition to the industrial user discharge permit application required above.)
(1) 
Such information, as a minimum, shall include:
(a) 
The name and address of the facility, including the name of the operators and the owners;
(b) 
A list of all environmental permits held by or for the facility;
(c) 
A brief description of the nature, average rate of production, and Standard Industrial Classification of the operations carried out at such facility;
(d) 
A schedule of actions to be taken to comply with the categorical standards;
(e) 
Information showing the measured average daily and maximum daily flow, in gallons per day, to the public sewer from regulated process streams and from other streams;
(f) 
An identification of the industrial pretreatment standards applicable to each regulated process; and
(g) 
An analysis identifying the nature and concentration of pollutants in the discharge.
(2) 
The Superintendent may require that additional information be included in such application.
G. 
As per 40 CFR 403.12(c), any compliance schedule must contain milestone dates for implementing pretreatment required to meet the applicable pretreatment standards for all users. Within 14 days of a milestone in the compliance schedule and within 14 days of the final date for compliance, all users, including Industrial Users, must submit a progress report to the POTW indicating whether or not the final compliance date was met and, if not, when the compliance with the increment of progress is expected.
H. 
Beginning 180 calendar days after the adoption of federal or state pretreatment standards, industries or any user subject to such standards may not discharge industrial wastes from processes regulated by such pretreatment standards to a public sewer unless an industrial discharge permit amendment is approved by the Superintendent and its terms are being met. Such permit amendment may include a compliance schedule for activities necessary to meet pretreatment standards or activities such as the installation of spill prevention and personnel training.
I. 
Within 90 days after the date for final compliance by existing industries with applicable categorical pretreatment standards or, in the case of a new source, following commencement of the introduction of wastewater into a public sewer, such industries shall submit a report indicating the nature and concentration of pollutants in the discharge from the regulated process(es) as governed by categorical pretreatment standards and the average and maximum daily flow for these process units. Such report shall state whether the applicable pretreatment standards are being met on a consistent basis and, if not, what additional operation and maintenance practices or pretreatment is necessary. Such industrial users shall also submit before June 1 and December 1 of each year, unless required more frequently by the Superintendent, a report indicating the nature and concentration of pollutants in the discharge, average and maximum daily flows, and violations of applicable categorical pretreatment standards. Baseline monitoring reports and reports on compliance with categorical standards (compliance reports) must contain a statement reviewed by an authorized representative of the industrial user, and certified by a qualified professional about the user's compliance with applicable categorical standards and whether any pretreatment or operation and maintenance is required to attain compliance. Additional requirements for such periodic reports may be imposed by the Superintendent. Significant noncategorical IUs shall also be required to submit periodic compliance reports at least once every six months (unless required more frequently by the Superintendent) which include the information as set forth in this section.
J. 
All categorical and noncategorical industrial users shall immediately (no later than 24 hours) notify the Superintendent in person or by telephone followed by written notice (within five days) of any slug discharged by such user.
K. 
Notice of violation by the industrial user to the POTW written within 24 hours of becoming aware of the violation will be followed by the user resampling and submitting the results of the resampling to the POTW within 30 days.
L. 
As per 40 CFR 12(j), all industrial users must notify the POTW prior to any substantial changes in the volume or character of pollutants in their discharges, including the listed or characteristic hazardous wastes for which the Industrial User has submitted initial notification under 40 CFR 403.12(p).
M. 
The Industrial User shall notify the POTW, the State DEP Hazardous Waste Authorities, and the EPA Regional Waste Management Division Director in writing of any discharge into the POTW which would be considered hazardous waste under 40 CFR Part 261, if disposed of in a different manner.
N. 
Reports and permit applications submitted by industries under this chapter shall be signed by an authorized representative. An authorized representative may be: a principal executive officer of at least a level of vice president, if the industrial user is a corporation; a general partner or the proprietor, if the industrial user is a partnership or sole proprietorship; or a duly authorized representative of either of the individuals designated above, if such representative is responsible for the overall operation of the subject facility. Baseline monitoring reports, ninety-day compliance reports and periodic compliance reports from categorical industrial users shall also contain the certification statement from 40 CFR 403.6(a)(2)(ii) as follows:
"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."
O. 
Industries subject to the reporting requirements of this chapter shall maintain records of information resulting from monitoring activities required to prepare such reports.
(1) 
Such records shall include, for each sample:
(a) 
The date, exact place, method and time of sampling and the names of the person or persons taking the sample;
(b) 
The dates analyses were performed;
(c) 
The name(s) of the person(s) performing the analyses;
(d) 
The analytical techniques and methods used; and
(e) 
The results of such analyses.
(2) 
Such records shall be maintained for a minimum of three years, or longer in case of unresolved litigation or when requested by the approval authority, and shall be made available for inspection and copying by the Superintendent.
P. 
Information and data submitted to the Superintendent relating to wastewater discharge characteristics shall be available to the public and governmental agencies without restriction. Other such information shall be available to the public and governmental agencies without restriction, unless the person providing such information specifically requests and is able to demonstrate to the satisfaction of the Superintendent that the release of such information would divulge processes or methods of production entitled to protection as trade secrets. Trade secrets shall not be made available for inspection by the public but may be made available upon the written request of governmental agencies for their use regarding this chapter, the National Pollutant Discharge Elimination System (NPDES) permit, and state disposal system permits and/or the pretreatment program.
Q. 
No person may utilize dilution as a means of complying with federal, state or local discharge limitations. The Superintendent may impose mass limitations (in addition to concentration limitations) on the discharge of any pollutant by any person.
R. 
The Superintendent shall annually publish the names of all industrial users in significant noncompliance (SNC) of this chapter during the previous 12 months in the largest daily newspaper published in the Town. For purposes of this provision, a significant noncompliance includes:
(1) 
A violation remaining uncorrected 45 days after notification of noncompliance;
(2) 
A failure to accurately report noncompliance; or
(3) 
A violation resulting in the Superintendent's exercise of emergency powers under § 93-21.
