Any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under Section 307(c) of the Act which will be applicable to such source if such standards are thereafter promulgated in accordance with that section of the Act, provided that:
(a) 
The building, structure, facility or installation is constructed at a site at which no other source is located; or
(b) 
The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
(c) 
The production or wastewater-generating processes of the building, structure, facility or installation are substantially independent of an existing source at the same site. In determining whether the sources are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant and the extent to which the new facility is engaged in the same general type of activity as the existing source should be considered.
(2) 
Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility or installation meeting the criteria of Subsection 1(b) or (c) above but otherwise alters, replaces or adds to existing process or production equipment.
(3) 
Construction of a new source as defined under this section has commenced if the owner or operator has:

No person shall make connection of roof downspouts, exterior foundation drains, areaway drains or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
G. 
The applicant for the building sewer permit shall notify the City when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the City Engineer or the Superintendent.
H. 
All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other work shall be restored in a manner satisfactory to the City.
I. 
All costs and expenses incident to the maintenance, repair or replacement of a private sewer line, regardless of whether said private sewer line is located on the owner's property or in the City's right-of-way, shall be the sole responsibility of the owner served by said private sewer line. Additionally, the owner shall indemnify the City from any loss or damage that may directly or indirectly be occasioned by the maintenance, repair or replacement of the building sewer. No owner shall commence maintenance, repair or replacement activities without first obtaining a permit from the Engineering Office pursuant to § 252-6.

§ 252-8 Sewer extensions.

A. 
Any extension of the City sewer system, whether for a public or private sewer, will only be allowed by the City Engineer. The City Engineer will authorize such extensions only after receipt of a written report from a professional engineer licensed by the State of Maine outlining the engineering, feasibility and estimated cost of such proposed extension, as well as an assessment of the potential properties benefiting from such action. The City Engineer must also receive prior written comments from the Director of Community and Economic Development as to the compliance of such an extension with relevant sections of the City's Comprehensive Plan before issuing authorization for the extension. The City Engineer must also receive prior written comments from the Superintendent of the Wastewater Treatment Plant as to the available capacity in the wastewater treatment system.
[Amended 7-22-2013 by Ord. No. 13-239]
B. 
The City Engineer will base the decision on any sewer extension request on the request's consistency with the provisions, and furtherance of the objectives, of the City's Comprehensive Plan and the specific criteria established in this chapter.
[Amended 7-22-2013 by Ord. No. 13-239]
C. 
Specifically, the City Engineer will authorize sewer extensions in consideration of the following mandatory requirements:
[Amended 7-22-2013 by Ord. No. 13-239]
(1) 
Said sewer extension lies within a defined primary service area and if said area is defined on an adopted primary service area map as provided for in the Comprehensive Plan; or
(2) 
Said sewer extension lies within the urban growth boundary and:
(a) 
The proposed sewer extension does not extend more than 500 feet beyond a primary service area boundary;
(b) 
The immediately adjacent primary service area has not been declared service deficient; and
(c) 
It shall have been determined that it is feasible to provide other critical services to the area to be served, including water, fire and police protection and adequate traffic capacity on existing or proposed streets.
(3) 
In either case under Subsection C(1) or (2) above, such an extension will not be installed in or through environmentally sensitive areas, such as wetlands, or in or through areas of extensive shallow depth to bedrock or other extreme physiographic conditions which would render, in the opinion of the City, the cost of installation and maintenance of such a sewer prohibitive.
D. 
Nothing in this section will prohibit the City Council, at its discretion, from extending public sewer service for public health reasons.

§ 252-9 General sewer use requirements.

A. 
General prohibitions. No discharger or 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 federal, state or local pretreatment standards or requirements. The provisions of this section shall apply to wastewater originating in the City, as well as wastewater originating in the Towns of Hampden and Hermon, which is introduced to the City's POTW.
B. 
Specific prohibitions. No discharger or user shall introduce or cause to be introduced into the POTW the following pollutants, substances or wastewater:
(1) 
Pollutants which create a fire or explosive hazard in the POTW, including but not limited to waste streams with a closed-cup flashpoint of less than 140º F. (60º C.) using the test methods specified in 40 CFR 261.21.
(2) 
Wastewater having a pH less than 5.0 or more than 12.0 or otherwise causing corrosive structural damage to the POTW or equipment. Any pH above 12.5 is considered hazardous under 40 CFR 261.22.
(3) 
Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference, but in no case shall solids greater than three inches or 7.6 centimeters in any dimension be introduced to the POTW.
(4) 
Pollutants, including oxygen-demanding pollutants (BOD, COD, 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.
(5) 
Wastewater having a temperature greater than 150º F. (65º C.) or which will inhibit biological activity in the POTW resulting in interference, but in no case wastewater which causes the temperature of the treatment plant influent of the POTW to exceed 104º F. (40º C.).
(6) 
Petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass-through.
(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) 
Trucked or hauled pollutants, except at discharge points designated by the Superintendent pursuant to § 252-18 of this chapter.
(9) 
Noxious or malodorous liquids, gases, solids or other wastewater which, either singly or by interaction with other wastes, is sufficient to create a public nuisance or a hazard to life or 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 MEPDES permit.
[Amended 6-9-2008 by Ord. No. 08-195]
(11) 
Stormwater, groundwater, roof runoff, subsurface drainage or any water from downspouts, yard drains, fountains and ponds, swimming pool drainage, sump pumps, septic tanks, lawn sprays or geothermal-type heating or cooling systems, unless such drainage from such sources is discharged into drains specifically designated for such purposes by the Superintendent. Industrial cooling water may be discharged only after approval and to a receptor site designated by the Superintendent. Such industrial cooling water discharges shall comply with the requirements of 38 M.R.S.A. § 413.
(12) 
Sludges, screenings or other residues or by-products from the pretreatment of industrial wastes.
(13) 
Wastewater containing any radioactive wastes or isotopes, except as specifically approved by the Superintendent. Such approval shall only be given upon certification by the discharger or user that applicable federal and state regulations concerning such wastewater have been complied with before such a discharge. Radioactive waste includes, but is not limited to, any substance required by the United States Department of Transportation to have Type A or B packaging, pursuant to 49 CFR 173.426.
(14) 
Medical wastes, except as specifically authorized by the Superintendent in a wastewater discharge permit.
(15) 
Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail a toxicity test.
(16)

[Amended 6-27-1994 by Ord. No. 94-274]
(17) 
Toxic pollutants or any other toxic substances hereinafter determined by the Superintendent not to be amenable to treatment or reduction by the wastewater treatment processes of the City or which might interfere with the effectiveness of the POTW's processes or which might limit the potential end uses of the POTW's sludges.
(18) 
Any substance or material prohibited under 40 CFR 403, in particular 403.5(a) and (b). Also any other substance or material the discharge of which results in a violation by the City of the regulations, now or herein after existing, of any public entity, including the EPA, or results in a violation of the City's MEPDES permit.
[Amended 6-9-2008 by Ord. No. 08-195]
(19) 
Any gasoline, benzene, naptha, fuel oil or other flammable or explosive liquids, solids or gases.
(20) 
Any garbage except properly shredded garbage.
(21) 
Any hazardous waste.
C. 
Action by Superintendent; outflow metering.
(1) 
If any wastewater or other wastes are discharged or proposed to be discharged to the public sewers, which wastewaters or other wastes contain the substances or possess the characteristics enumerated in this section and which in the judgment of the Superintendent may have a deleterious effect upon the City's POTW processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
(a) 
Reject the wastewater or other wastes;
(b) 
Require pretreatment to an acceptable condition for discharge to the POTW;
(c) 
Require control over the quantities and rates of discharge;
(d) 
Require payment to cover the added cost of handling and treating the wastes; and/or
(e) 
Take any appropriate enforcement action against an industrial user or user which violates the prohibitions of this section.
(2) 
If the Superintendent permits the pretreatment or flow equalization of waste flows, the design and installation of the plant and equipment for such pretreatment or flow equalization shall be subject to the review and approval of the Superintendent and subject to the requirements of all applicable City, state and federal codes, ordinances and laws. The Superintendent's approval, if granted, shall not be deemed to relieve the discharger of its responsibility to comply with its wastewater discharge permit requirements and shall not constitute an acceptance of the adequacy of the pretreatment process equipment selected. Where preliminary treatment or flow-equalizing facilities are provided for any wastewater or other wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at the owner's expense.
(3) 
Outflow metering.
[Amended 10-30-1994 by Ord. No. 95-8]
(a) 
Whenever the Superintendent has reason to believe that a particular discharger is discharging unmetered flows into the City's POTW or public sewers in the form of storm runoff, groundwater, roof runoff or subsurface drainage or from any other source listed in Subsection B(11) of this section or otherwise and that the volume of such flows, on a percentage basis, exceeds the City-wide average for such flows, the Superintendent may install, or require the discharger to install, an outflow metering device and may thereafter charge the discharger the City's cost, if any, of installing the outflow metering device and the City's cost of treating such flows as provided in the City's approved schedule of sewer fees. All charges imposed by the Superintendent under this Subsection C(3) shall be collected in the same manner as other sewer fees established under 30-A M.R.S.A. § 5405.
(b) 
Prior to imposing charges under this Subsection C(3), the Superintendent shall give the discharger written notice of a show cause hearing, as provided in § 252-20D of this chapter. At the show cause hearing, the discharger shall be afforded an opportunity to show that its discharges into the City's POTW or public sewers do not include excessive unmetered flows or that such flows were caused by an upset or unavoidable malfunction. For this purpose, the term "unavoidable malfunction" shall be defined as provided in 38 M.R.S.A. § 359, Subsection 9. In the event of excessive unmetered flows caused by an unavoidable malfunction, the Superintendent shall issue an order directing correction of the malfunction within 90 days of the order date. This period may be extended for an additional period of up to 90 days if the malfunction cannot be corrected within the original ninety-day period due to winter weather conditions. If the malfunction remains uncorrected upon expiration of the specified period, the Superintendent shall impose the additional charges provided in this Subsection C(3) retroactively to the date of the Superintendent's order.
(c) 
Imposition of additional charges as provided in this Subsection C(3) shall not bar or be a prerequisite for other enforcement action under § 252-20, 252-21 or 252-22 of this chapter.
D. 
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, sand or other harmful ingredients, except that such interceptors shall not be required for private residential living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located so as to be readily and easily accessible for cleaning and inspection.
E. 
No discharger or user shall increase the use of potable or process water, in any way, 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 chapter. Pollutants, substances or wastewater prohibited by this section shall not be processed or stored in a manner that would allow it to be discharged to the POTW.
F. 
Federal Categorical Pretreatment Standards. The categorical pretreatment standards found at Title 40 of the Code of Federal Regulations, Chapter I, Subchapter N, Parts 405 through 471, are incorporated herein by reference. These standards must be adhered to by dischargers to, or users of, the POTW.
[Amended 6-9-2008 by Ord. No. 08-195]
(1) 
When a categorical pretreatment standard is expressed only in terms of pollutant concentrations, an industrial user may request that the City convert the limits to equivalent mass limits. The determination to convert concentration limits to mass limits is within the discretion of the Superintendent. The City may establish equivalent mass limits only if the industrial user meets all the conditions set forth in Subsection F(1)(a) through (c) below.
(a) 
To be eligible for equivalent mass limits, the industrial user must:
[1] 
Employ, or demonstrate that it will employ, water conservation methods and technologies that substantially reduce water use during the term of its individual wastewater discharge permit;
[2] 
Currently use control and treatment technologies adequate to achieve compliance with the applicable pretreatment standard and not have used dilution as a substitute for treatment;
[3] 
Provide sufficient information to establish the facility's actual average daily flow rate for all wastestreams, based on data from a continuous effluent flow monitoring device, as well as the facility's long-term production rate. Both the actual average daily flow rate and the long-term average production rate must be representative of current operating conditions;
[4] 
Not have daily flow rates, production levels, or pollution levels that vary so significantly that equivalent mass limits are not appropriate to control the discharge; and
[5] 
Have consistently complied with all applicable categorical pretreatment standards during the period prior to the industrial user's request for equivalent mass limits.
(b) 
An industrial user subject to equivalent mass limits must:
[1] 
Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits;
[2] 
Continue to record the facility's flow rates through the use of a continuous flow monitoring device;
[3] 
Continue to record the facility's production rates and notify the Superintendent whenever production rates are expected to vary by more than 20% from its baseline production rates determined in Subsection F(1)(a)[3] of this section. Upon notification of a revised production rate, the Superintendent will reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility; and
[4] 
Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to Subsection F(1)(a)[1] of this section so long as it discharges under an equivalent mass limit.
(c) 
When developing equivalent mass limit, the Superintendent:
[1] 
Will calculate the equivalent mass limit by multiplying the actual average daily flow rate of the regulated process(es) of the industrial user by the concentration-based daily maximum and monthly average standard for the applicable categorical pretreatment standard and the appropriate unit conversion factor;
[2] 
Upon notification of a revised production rate, will reassess the equivalent mass limit and recalculate the limit as necessary to reflect changed conditions at the facility; and
[3] 
May retain the same equivalent mass limit in subsequent individual wastewater discharger permit terms if the industrial user's actual average daily flow rate was reduced solely as a result of the implementation of water conservation methods and technologies, and the actual average daily flow rates used in the original calculation of the equivalent mass limit were not based on the use of dilution as a substitute for treatment pursuant to § 252-9E. The industrial user must also be in compliance § 252-23C regarding the prohibition of bypass.
(2) 
Once included in its permit, the industrial user must comply with the equivalent limitations developed as per this section in lieu of the promulgated categorical standards from which the equivalent limitations were derived.
(3) 
Any industrial user operating under a permit incorporating equivalent mass or concentration limits calculated from a production-based standard shall notify the Superintendent within two business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not notifying the Superintendent of such anticipated change will be required to meet the mass or concentration limits in its permit that were based on the original estimate of the long-term average production rate.
G. 
Local limits.
(1) 
Limits for certain pollutants will be established to protect against pass-through or interference. No person shall discharge wastewater containing in excess of the instantaneous maximum allowable discharge limits as identified on the user's wastewater discharge permit. All discharge local limits shall be technically based and approved by the DEP.
[Amended 6-9-2008 by Ord. No. 08-195]
(2) 
Local limits may be set for the following pollutants: arsenic, barium, cadmium, chromium, copper, cyanide, lead, mercury, nickel, fats, oils or other greases of animal or vegetable origin or oil and grease and other petroleum or mineral oil products, silver, TTO and zinc. This list may be amended or local limits may be developed for any other pollutants deemed appropriate, including pollutants that can cause pass-through, interference, worker health and safety problems, fume toxicity, etc. The City will provide advanced written notice of new local limits to users prior to initiating enforcement actions.
[Amended 6-27-1994 by Ord. No. 94-274]
(3) 
The discharge local limits must be met at the point where the user's wastewater is discharged to the POTW. All concentrations for metallic substances are for total metal unless otherwise indicated on the wastewater discharge permit. The Superintendent may impose mass limitations in addition to or in place of concentration-based limitations.
(4) 
The Superintendent may develop best management practices (BMPs) and mass-based limits by ordinance or in individual wastewater discharge permits, to implement local limits and any other general discharge prohibitions as defined in § 252-9.
[Added 6-9-2008 by Ord. No. 08-195]
H. 
City's right of revision. The City reserves the right to establish, by ordinance or in wastewater discharge permits, more stringent standards or requirements on discharges to the POTW.
I. 
Special agreement. The City reserves the right to enter into special agreements with users setting out special terms under which they may discharge to the POTW. In no case will a special agreement waive compliance with a pretreatment standard or requirement. However, the user may request a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. A user may also request a variance from the categorical pretreatment standard from the approval authority. Such a request will be approved only if the user can prove that the factors relating to its discharge are fundamentally different from the factors considered by the EPA when establishing that categorical pretreatment standard. A user requesting a fundamentally different factor variance must comply with the procedural and substantive provisions in 40 CFR 403.13. The City is authorized to set appropriate fees or other charges for such agreements.
J. 
Pretreatment facilities. Users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in this chapter within the time limitations specified by the EPA, the state or the Superintendent, whichever is more stringent. Any facilities required to pretreat wastewater to a level acceptable to the City shall be provided, operated and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the City for review and shall be approved by the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the City's POTW under the provisions of this chapter.
K. 
Accidental discharge/slug control plans. The Superintendent may require any user to develop and implement an accidental discharge/slug control plan. At least once every two years the Superintendent shall evaluate whether each significant industrial user needs such a plan. Any user required to develop and implement an accidental discharge/slug control plan shall submit a plan which addresses, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharges in this section of this chapter; and
(4) 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents) and/or measures and equipment for emergency response.

§ 252-10 Wastewater surveys.

A. 
It shall be unlawful to discharge wastewater to the City's POTW or to any public or private sewer within the Towns of Hampden and Hermon where such discharged wastewater reaches the City's POTW without having first complied with the provisions of this chapter.
B. 
When requested by the Superintendent, all users must complete a wastewater survey form, on a form supplied by the City, which contains information on the nature and characteristics of their wastewater. This form must be submitted to the Superintendent prior to discharge of the user's wastewater into the City's POTW. The Superintendent is authorized to prepare a form for this purpose and may periodically require users to update the survey. Failure to complete this wastewater survey form shall be reasonable grounds for terminating service to the user and shall be considered a violation of this chapter. Existing industrial dischargers shall file wastewater survey forms within 30 days after being notified by the City, and proposed new dischargers shall file such forms at least 90 days prior to connecting to the POTW. The information to be supplied to the Superintendent by the user shall include, but not be limited to, the following information:
(1) 
The name, address and location of the user and the number of employees.
(2) 
The SIC of the user.
(3) 
The known or suspected to be present wastewater constituents and characteristics, including but not limited to those mentioned in this chapter. Any sampling and analysis that is required by the City shall be performed in accordance with standard methods and/or those contained in 40 CFR 136. The costs of all such sampling, analysis and reporting shall be fully borne by the user.
(4) 
The time and duration of discharges.
(5) 
The average daily and instantaneous peak wastewater flow rates, in gallons per day, including daily, monthly and seasonal variations, if any. All flows shall be as actually measured unless other verifiable techniques are approved by the City due to cost or nonfeasibility.
(6) 
The site plans, floor plans, mechanical and plumbing plans and details to show all sewers, sewer connections, inspection manholes, sampling chambers and appurtenances by size, location and elevation adjacent to or at the user's premises.
(7) 
The activities, facilities and plant process on the premises, including all materials which are or may be discharged to the POTW.
(8) 
The nature and concentration of any known or suspected pollutants or materials prohibited by this chapter from being included in the discharge, together with a statement regarding whether or not compliance is being achieved with this chapter on a consistent basis and, if not, whether additional O&M activities and/or additional pretreatment is required for the user to comply with this chapter.
(9) 
The identification of each product produced by the user by type, amount, process or processes and rate of production.
(10) 
The type and amount of raw materials utilized, average and maximum per day, by the user.
C. 
All disclosure forms and any periodic reports submitted by a user shall be signed by the principal executive officer of the user and shall contain the following certification: "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 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."
D. 
The City will evaluate the completed wastewater survey forms and material safety data sheets furnished by the user and may require the user to furnish additional information. The user shall provide all requested additional information within 15 days after receiving notification from the City that additional information is required. After full evaluation and acceptance of all submitted data, the Superintendent shall make the determination as to whether the user is subject to EPA pretreatment requirements. If the Superintendent determines that the user is subject to EPA pretreatment requirements, the City shall require the user to apply for a wastewater discharge permit as required by § 252-11 of this chapter. The user shall make application for a wastewater discharge permit, on a form provided by the City, within 30 days after having received notification from the City to do so. The user shall provide, with the permit application, at the user's own expense, the results of all sampling and analysis of the user's wastewater effluent as the City may require to accompany the permit application. If so requested by the City, the user shall collect all required samples in the presence of the Superintendent.
[Amended 9-14-1998 by Ord. No. 98-339]

§ 252-11 Wastewater discharge permits.

A. 
Every new or existing user of the City's POTW or wastewater plant which is determined to be a categorical user or significant industrial user as defined in § 252-3 of this chapter is required to obtain a wastewater discharge permit from the Superintendent.
B. 
The Superintendent may prescribe special license, disclosure and reporting requirements for nonindustrial users of high-strength conventional waste distinct from the requirements imposed on industrial users under this section. Such requirements shall not be more burdensome than the requirements imposed on industrial users by this section.
C. 
Wastewater discharge permits shall be subject to all provisions of this chapter and all other regulations, user charges and fees established by the City. The conditions of wastewater discharge permits shall be enforced in accordance with this chapter and applicable state and federal regulations.
D. 
Wastewater discharge permits may impose effluent restrictions or limits on the user if the Superintendent determines that such limits are necessary to protect the quality of the treatment plant influent, effluent or sludge or to maintain compliance with any applicable federal or state law, including requirements under the City's NPDES permit and national categorical pretreatment standards for new and existing sources set out in Title 40 of the Code of Federal Regulations, Chapter I, Subchapter N, Parts 401 through 471.
E. 
The Superintendent will evaluate the data furnished by the user and may require additional information to complete the user's wastewater discharge permit application. Within 14 days of receipt of a complete wastewater discharge permit application, the Superintendent will determine whether a wastewater discharge permit is required and, if so, whether a wastewater discharge permit should be issued. The Superintendent may deny any application for a wastewater discharge permit. The Superintendent shall notify the user, in writing, of the decision on the wastewater discharge permit application.
F. 
Wastewater discharge permits shall be issued for a specified time period, not to exceed five years. Each wastewater discharge permit shall indicate a specific date upon which it will expire.
[Amended 6-9-2008 by Ord. No. 08-195]
G. 
Wastewater discharge permits are issued to a specific operation. A wastewater discharge permit shall not be reassigned or transferred or sold to a new owner or a new user, different premises or a new or changed operation. To facilitate the issuance of new, separate permits, the Superintendent may allow new owners or individuals to operate under an existing wastewater discharge permit for a period not to exceed 90 days.
H. 
Wastewater discharge permits shall include such conditions as are reasonably deemed necessary by the Superintendent to prevent pass-through or interference, protect the quality of the water body receiving the treatment plant's effluent, protect worker health and safety, facilitate sludge management and disposal and protect against damage to the POTW.
(1) 
Wastewater discharge permits shall contain the following conditions:
(a) 
A statement that indicates the wastewater discharge permit duration.
(b) 
A statement that indicates that the wastewater discharge permit is nontransferable pursuant to Subsection G of this section and a provision requiring any new owner or operator to be furnished with a copy of the existing wastewater discharge permit by the prior user.
(c)

[Amended 6-9-2008 by Ord. No. 08-195]
(d) 
Self-monitoring, sampling, reporting, notification and recordkeeping requirements. These requirements shall include a sampling frequency and sample type based on federal, state and local law.
(e) 
A statement of applicable penalties for violation of pretreatment standards and requirements and any required compliance schedule. Such schedule may not extend the time for compliance beyond that required by federal, state or local law.
(f) 
Other specific conditions the Superintendent deems necessary to ensure compliance with this chapter and federal and state regulations and statutes.
(2) 
Wastewater discharge permits may contain, but need not be limited to, the following conditions:
(a) 
Limits on the average and/or maximum rate of discharge, time of discharge and/or requirements for flow regulation and flow equalization.
(b) 
Limits on the instantaneous, daily and monthly average and/or maximum concentration, mass or other measure of identified wastewater pollutants or properties.
(c) 
Requirements for the installation of pretreatment technology, pollution control or construction of appropriate containment devices, any of which would be designed to reduce, eliminate or prevent the introduction of pollutants into the POTW.
(d) 
Requirements for the development and implementation of spill and/or slug control plans or other special conditions, including management practices necessary to adequately prevent accidental, unanticipated or routine discharge.
[Amended 6-9-2008 by Ord. No. 08-195]
(e) 
Development and implementation of waste minimization plans to reduce the amount of pollutants discharged to the POTW by the user.
(f) 
The unit charge or schedule of user charges and fees for the management of the user's wastewater discharged to the POTW.
(g) 
Requirements for the installation and maintenance of inspection and sampling facilities and equipment.
(h) 
A statement that compliance with the wastewater discharge permit does not relieve the permittee of responsibility for compliance with all applicable federal and state pretreatment standards, including those which become effective during the term of the wastewater discharge permit.
(i) 
Identification by the user of the location of the user's outfall to the POTW.
(j) 
Other specific conditions the Superintendent deems necessary to ensure compliance with this chapter and federal and state regulations and statutes.
I. 
Any aggrieved person, including the user, may file a petition with the City, in writing, to reconsider the terms of a wastewater discharge permit or the denial of a wastewater discharge permit application within 15 days of the permit's issuance or notification of the Superintendent's denial.
(1) 
Failure to submit a timely petition for review shall be deemed to be a waiver of any administrative appeal.
(2) 
In its petition, the petitioner must indicate the wastewater discharge permit provisions objected to, the reasons for this objection and the alternative condition, if any, it seeks to place in the wastewater discharge permit. A petitioner seeking review of a permit denial must specifically allege reasons why a permit should be issued, along with conditions of issuance that the petitioner believes should satisfy any concerns the City may have about the suitability of the user's wastewater for discharge to the City's POTW.
(3) 
The requirements or conditions of any wastewater discharge permit shall not be stayed by the City pending the outcome of the administrative appeal.
(4) 
Upon receipt of the petition, the Superintendent may act to grant the petitioner's request. Said action must take place within 14 days of receipt of the petition.

The City will follow the ERP to the greatest extent possible when contemplating compliance with and enforcement of this chapter; however, nothing in the ERP or this chapter will preclude or otherwise limit the City from taking any action, including emergency actions or other enforcement actions, prior to undertaking any initial enforcement procedure in the ERP, including issuance of a notice of violation (NOV).
B. 
Notice of violation. When the Superintendent finds that a user has violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement, the Superintendent may serve upon that user a written NOV. Within 30 days of the receipt of this notice, an explanation of the violation and a plan for the satisfactory correction and prevention thereof, which must include specific required actions, shall be submitted by the user to the Superintendent. Submission of this plan in no way relieves the user of liability for any violations occurring before or after receipt of the NOV.
C. 
Consent orders. The Superintendent may enter into consent orders, assurances of voluntary compliance or other documents establishing an agreement with any user responsible for noncompliance. Such documents will include specific action to be taken by the user to correct the noncompliance within a time period specified by the document. Such documents shall have the same force and effect as the administrative orders issued pursuant to Subsections E and F of this section and shall include language which make them judicially enforceable. Such orders may require the payment of administrative fines pursuant to Subsection G of this section.
D. 
Show cause hearing. The Superintendent may order a user which has violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement to appear before the Superintendent and show cause why the proposed enforcement should not be taken. Notice shall be served on the user specifying the time and place for the meeting, the proposed enforcement action, the reasons for such action and a request that the user show cause why the proposed enforcement action should not be taken. The notice of the meeting shall be served personally by the Superintendent or by registered or certified mail, return receipt requested, at least 14 days prior to the hearing. Such notice may be served on any authorized representative of the user. A show cause hearing shall not be a bar against, or prerequisite for, taking any other action against the user. Failure to appear for a show cause hearing may be grounds for revocation of the user's wastewater discharge permit and disconnection from or termination of discharge to the POTW.
E. 
Compliance orders. When the Superintendent finds that a user has violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement, the Superintendent may issue an order to the user responsible for the discharge directing that the user comes into compliance within 30 days. If the user does not come into compliance within 30 days, sewer service shall be discontinued unless adequate treatment facilities, devices or other related appurtenances are installed and properly operated. Compliance orders may also contain other requirements to address the noncompliance, including additional self-monitoring and management practices designed to minimize the amount of pollutants discharged to the POTW. A compliance order may not extend the deadline for compliance established for a federal pretreatment standard or requirement, nor does a compliance order relieve the user of liability for any violation, including any continuing violation. Issuance of a compliance order shall not be a bar against, or a prerequisite for, taking any other action against the user.
F. 
Cease and desist orders.
(1) 
When the Superintendent determines that a user violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement or that the user's past violations are likely to recur, the Superintendent may issue an order to the user directing it to cease and desist any such violations and directing the user to:
(a) 
Immediately comply with all requirements; and
(b) 
Take such appropriate remedial or preventative action as may be needed to properly address a continuing or threatened violation, including halting operations and/or terminating the discharge to the POTW.
(2) 
Issuance of a cease and desist order shall not be a bar against, or a prerequisite for, taking any other action against the user.
G. 
Administrative fines.
(1) 
When the Superintendent finds that a user violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement, including a user's failure to obtain a wastewater discharge permit pursuant to § 252-11 of this chapter, the Superintendent may fine such user in an amount not to exceed $2,500 per day. Each day of violation shall constitute a separate offense subject to fine. In the case of monthly or other long-term average discharge limits, fines shall be assessed for each day during the period of violation. In the case of failure to obtain a required wastewater discharge permit, the fine shall accrue on a daily basis commencing on the day the user first was notified or became aware of the need for such a permit. The City may add the costs of preparing administrative enforcement actions, such as notices and orders, to any fine assessed.
(2) 
Any and all unpaid charges, fines and penalties under this chapter shall, after 30 calendar days from the due date, be assessed an additional penalty of 12% of the unpaid balance, and interest shall accrue thereafter at a rate of 1% per month. A lien against the user's property may be sought for unpaid charges, fines and penalties as allowed under state law.
(3) 
Users desiring to dispute such fines must file a written request for the Superintendent to reconsider the fine along with full payment of the fine amount within 30 days of being notified of the fine. The Superintendent shall convene an administrative hearing on the matter and conduct said hearing in accordance with the procedures delineated in § 252-11I(4) of this chapter. Failure to timely request an administrative hearing constitutes a waiver of any administrative appeal. The decision of the Committee conducting the administrative hearing, including a decision to not reduce the fine, shall be final, and any appeal must follow the requirements of Maine Rules of Civil Procedure 80B. In the event that the user's appeal is successful, the payment, together with any interest accruing thereto, shall be returned to the user.
(4) 
Issuance of an administrative fine shall not be a bar against, or a prerequisite for, taking any other action against the user.
H. 
Emergency suspensions. The Superintendent may immediately suspend a user's discharge either with or without written or verbal notice to the user whenever such suspension is necessary to stop an actual or threatened discharge which reasonably appears to present or cause an imminent or substantial endangerment to the health or welfare of the public. The Superintendent may also immediately suspend a user's discharge, either with or without written or verbal notice, that threatens to interfere with the operation of the POTW or which presents or may present an endangerment to the environment.
(1) 
Any user notified of a suspension of its discharge shall immediately stop or eliminate its discharge to the POTW. In the event of a user's failure to immediately comply voluntarily with the suspension order, the Superintendent shall take such steps as deemed necessary, including immediate severance of the connection to the POTW, to prevent or minimize damage to the POTW, its receiving waters or endangerment to any persons. The Superintendent shall allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the City that the period of endangerment has passed, unless the termination proceedings in Subsection I of this section are initiated against the user.
(2) 
A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement to the Superintendent describing the causes of the harmful contribution and the measures taken to prevent any future occurrence. Said report must be submitted as least seven days prior to the date of any show cause or termination hearing held pursuant to Subsections D and I of this section.
(3) 
Nothing in this subsection shall be interpreted as requiring a hearing prior to any emergency suspension under this subsection.
I. 
Termination of discharge.
(1) 
In addition to the provisions in § 252-11K of this chapter, any user that violates the following conditions is subject to termination of the user's discharge to the POTW:
(a) 
Violation of wastewater discharge permit conditions;
(b) 
Failure to accurately report the wastewater constituents and characteristics of the user's discharge;
(c) 
Failure to report significant changes in operations or wastewater volume, constituents and characteristics prior to discharge;
(d) 
Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring or sampling; or
(e) 
Violation of the pretreatment standards in § 252-9 of this chapter.
(2) 
Such user will be notified of the proposed termination of its discharge and be offered an opportunity to show cause pursuant to Subsection D of this section why the proposed action should not be taken. Additionally, the user may request an administrative hearing, in writing, within 30 days of the decision of the show cause hearing. The hearing shall be conducted in accordance with the procedures delineated in Subsection G(3) of this section. Exercise of this option by the City shall not be a bar to, or a prerequisite for, taking any other action against the user.

§ 252-21 Judicial enforcement remedies.

A. 
Injunctive relief. When the Superintendent determines that a user has violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement, the Superintendent may request that the City Solicitor seek appropriate injunctive relief pursuant to the laws of this state which restrains or compels the specific performance of the conditions of the wastewater discharge permit, order or other requirements imposed by this chapter on activities of the user. The City may also seek such other action as is appropriate for legal and/or equitable relief, including a requirement for the user to conduct environmental remediation. The decision whether to seek injunctive relief shall not be a bar against, or a prerequisite for, taking any other action against a user.
B. 
Civil penalties and criminal referral.
(1) 
Any person who violates the provisions of this chapter shall be subject to civil penalties pursuant to 30-A M.R.S.A. § 4452, as well as applicable civil or criminal penalties pursuant to 38 M.R.S.A. §§ 349 and 1319-T. The penalties in those statutes shall be in addition to the specific penalties in this chapter.
(2) 
A user which has violated or continues to violate any provision of this chapter, a wastewater discharge permit or other permit issued hereunder or any other pretreatment standard or requirement shall be required to pay a fine of not less than $1,000 per day and not more than $2,500 per day for each and every day of a violation for a first offense. These fines shall increase to a minimum of $2,500 per day and a maximum of $25,000 per day for a second offense of the same or a similar nature occurring within two years of the first offense. Each day of violation shall constitute a separate offense subject to fine. In the case of a monthly or other long-term average discharge limit, penalties shall accrue for each day during the period of the violation.
(3) 
Pursuant to 30-A M.R.S.A. § 4452 and Maine Rules of Civil Procedure 80K, the City may seek reasonable attorney fees, court costs and other expenses associated with enforcement activities, including sampling and monitoring expenses, and the cost of any actual damages incurred by the City.
(4) 
In determining the amount of civil liability, the court shall be asked to take into account all relevant circumstances, including but not limited to the extent of harm caused by the violation, the magnitude and duration, any economic benefit gained through the user's violation, corrective actions undertaken by the user, the compliance history of the user and any other factor as justice requires.
(5) 
No person shall willfully or negligently break, damage, destroy, uncover, deface, tamper with or prevent access to any structure, appurtenance or equipment or other part of, or otherwise harm, the POTW. Penalties for violations of this provision of this chapter shall be a minimum fine of $1,000 for the first offense. A second offense committed within five years shall be punished by a minimum fine of $10,000. These penalties are in addition to any penalties associated with other civil or criminal provisions of state and federal law which said person may be subject to for such action.
[Amended 6-9-2008 by Ord. No. 08-195]
C. 
Filing a suit for civil penalties or making a criminal referral shall not be a bar against, or a prerequisite for, taking any other action against a user.
D. 
The City reserves the right to make appropriate referrals for criminal prosecution pursuant to the provisions of 38 M.R.S.A. §§ 349 and 1319-T, as well as any other applicable federal or state law. Additionally, enforcement of this chapter shall not preclude criminal prosecution for other violations of state or federal law, and the City will cooperate in any such prosecutions.
E. 
The provisions of §§ 252-20 and 252-21 of this chapter are not exclusive remedies. The City reserves the right to take any and all enforcement actions or combinations thereof against a noncompliant user.

§ 252-22 Supplemental enforcement action.

A. 
Performance bonds. The Superintendent may decline to issue or reissue a wastewater discharge permit to any user which has failed to comply with any provision of this chapter, a previous wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement unless such user first files a satisfactory bond with the City, payable to the City, in a sum not to exceed a value determined by the Superintendent to be necessary to achieve consistent compliance with this chapter.
B. 
Liability insurance. The Superintendent may decline to issue or reissue a wastewater discharge permit to any user which has failed to comply with any provision of this chapter, a previous wastewater discharge permit or order issued hereunder or any pretreatment standard or requirement unless the user first submits proof that it has obtained financial assurances sufficient to restore or repair damage to the POTW caused by its discharge, which shall include naming the City as an additional insured.
C. 
Water supply severance. Whenever a user violates or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder or any other pretreatment standard or requirement, the City will work with the Bangor Water District to sever water service to the user under district regulations, if applicable. Service will only recommence at the user's expense, after the user has satisfactorily demonstrated its ability to comply with this chapter.

§ 252-23 Affirmative defenses to discharge violations.

A. 
Upset.
(1) 
An upset shall constitute an affirmative defense to an action brought for noncompliance with categorical pretreatment standards if the requirements of Subsection A(2) are met.
(2) 
A user which wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence, that:
(a) 
An upset occurred and the user can identify the cause(s) of the upset;
(b) 
The facility was at the time being operated in a prudent and workmanlike manner and in compliance with applicable O&M procedures; and
(c) 
The user has submitted the following information to the Superintendent within 24 hours of becoming aware of the upset. If this information is provided orally, a written submission must be provided within five days.
[Amended 6-9-2008 by Ord. No. 08-195]
[1] 
A description of the indirect discharge and cause of noncompliance;
[2] 
The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time period the noncompliance is expected to continue; and
[3] 
Steps being taken and/or planned to reduce, eliminate and prevent reoccurrence of the noncompliance.
(3) 
In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof.
(4) 
Users will have the opportunity for a judicial determination on any claim of upset only in an enforcement action brought for noncompliance with categorical pretreatment standards.
(5) 
Users shall control production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards upon reduction, loss or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost or fails.
B. 
Prohibited discharge standards. A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general prohibitions in § 252-9A of this chapter or the specific prohibitions in § 252-9B(3) through (18) and (20) of this chapter if it can prove that it did not know, or have reason to know, that its discharge, alone or in conjunction with discharges from other sources, would cause pass-through or interference and that either:
(1) 
A local limit exists for each pollutant discharged and the user was in compliance with each limit directly prior to, and during, the pass-through or interference; or
(2) 
No local limit exists, but the discharge did not change substantially in nature or constituents from the user's prior discharge when the City was regularly in compliance with its NPDES permit and, in the case of interference, was in compliance with applicable sludge use or disposal requirements.
C. 
Bypass.
(1) 
For the purposes of this chapter, the following terms shall have the meanings indicated:
BYPASS
The intentional diversion of waste streams from any portion of a user's treatment facility.
SEVERE PROPERTY DAMAGE
Any substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.
(2) 
A user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of Subsection C(3) and (4) of this section.
(3) 
Notice.
(a) 
If a user knows in advance of the need for a bypass, it shall submit prior notice to the Superintendent at least 10 days before the date of the bypass, if possible.
(b) 
A user shall submit oral notice to the Superintendent of an unanticipated bypass that exceeds applicable pretreatment standards within 24 hours from the time it becomes aware of the bypass. A written submission shall also be provided within five days of the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; the duration of the bypass, including exact dates and times and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate and prevent reoccurrence of the bypass. The Superintendent may waive the written report on a case-by-case basis if the oral report has been received within 24 hours.
(4) 
Enforcement action.
(a) 
Bypass is prohibited, and the Superintendent may take an enforcement action against a user for a bypass, unless:
[1] 
Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
[2] 
There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and
[3] 
The user submitted notices as required under Subsection C(3) of this section.
(b) 
The Superintendent may approve an anticipated bypass, after considering the adverse effects, if the Superintendent determines that it will meet the three conditions listed in Subsection C(4)(a) of this section.

§ 252-24 Wastewater treatment rates.

A. 
All persons within the City who are, or will be, connected into the City's POTW shall be subject to a sewer use charge. A schedule of charges shall be established from time to time by City Council order. The sewer use charges are to be based on water meter readings of the user, type of wastewater discharged to the POTW based on the use of the user's premises and/or other parameters determined by the City to be necessary to cover the cost of construction and operation and maintenance of the City's POTW. There shall be no discounts or abatements given for sewer use charges unless such discounts or abatements are provided in accordance with the provisions outlined in § 252-25 below. So long as users in the Town of Hermon are billed by the City, Hermon users may be billed in a manner that is the same or different from the City's users.
[Amended 8-28-1995 by Ord. No. 95-359]
B. 
The schedule of charges may be changed from time to time to conform to new state and/or federal criteria and to conform to the current costs of construction and O&M associated with the City's POTW. The current schedule of user charges, the method of measurement and collection and all other regulations pertaining thereto shall be available for public inspection in the office of the City Clerk and the Superintendent.
[Amended 6-9-2008 by Ord. No. 08-195]
C. 
Pretreatment charges and fees. The City may adopt reasonable fees for reimbursement of the costs of setting up and operating the City's pretreatment program, including but not limited to the following:
(1) 
Fees for wastewater discharge permit applications, including the cost of processing such applications;
[Amended 6-9-2008 by Ord. No. 08-195]
(2) 
Fees for monitoring, inspection and surveillance procedures, including the cost of collection and analyzing a user's discharge and reviewing monitoring reports submitted by users;
(3) 
Fees for reviewing and responding to accidental discharge procedures and/or construction;
(4) 
Fees for filing administrative appeals; and
(5) 
Other fees as the City may deem necessary to carry out the requirements contained herein. These fees will relate solely to the matters covered by this chapter.
D. 
Surcharge fees.
[Amended 6-9-2008 by Ord. No. 08-195]
(1) 
In addition to any penalties and fines required by this chapter and state or federal law, as well as regular sewer use charges, the City shall impose surcharge fees on any user that discharges into the POTW and the discharge causes or constitutes the following:
(a) 
Slug or slug load;
(b) 
Interference;
(c) 
Pass-through;
(d) 
Excessive loadings, including excessive loading caused by high-strength conventional waste from a nonpermitted user;
(e) 
Violations of § 252-9 of this chapter; or
(f) 
Any other discharge which adversely affects the POTW or increases the City's cost of treating wastewater in the City's POTW.
(2) 
Surcharges shall not exceed 50% of the normal sewer user charges, unless said amount is necessary to offset the City's cost of treating the discharged material, including any costs incurred by the City for violations of the City's MEPDES permit.
E. 
All surcharge fees and pretreatment charges and fees shall be set from time to time by the Superintendent and shall be kept on file for public inspection with the City Clerk and the Superintendent.
[Amended 6-9-2008 by Ord. No. 08-195]
F. 
The City may establish fees for the disposal of hauled wastewater and special agreements. These fees shall be consistent with, but not necessarily the same as, regular sewer use charges. They shall be set from time to time by City Council order or by contractual agreements approved by the City Council and be kept on file for public inspection with the City Clerk and the Superintendent.
[Amended 6-9-2008 by Ord. No. 08-195]
G. 
Interest shall be collected upon all unpaid sewer use charges, surcharges, hauled wastewater fees and fees and charges associated with pretreatment which remain unpaid after the due date. The rate of interest shall be as set by the Finance Director for the payment of delinquent property taxes, which rate shall not exceed the highest interest rate allowed by state law for municipal property taxes.
[Amended 6-9-2008 by Ord. No. 08-195]
H. 
Roof drains. An additional quarterly charge which may be established from time to time by Council order shall be assessed against any property where roof drains are directly connected to the City's sanitary and/or combined sewer systems. In instances where a single account includes multiple dwelling units or commercial or industrial establishments, this charge shall be increased by multiplying the quarterly fee by the number of such residential, commercial and industrial units. The quarterly charge shall be billed in arrears and shall only be charged against those accounts where roof drains remain connected to the sanitary and/or combined sewer systems as of the date the water meter is read. These charges shall be made on accounts read on or after December 31, 1997. It shall be the responsibility of the property owner or his or her agents to provide information satisfactory to the Superintendent of the treatment plant that all roof drains have been disconnected from the sanitary and/or combined sewer systems in order to avoid such charges.
[Amended 9-25-1996 by Ord. No. 96-371]
I. 
Availability fee. An availability fee shall be charged to all properties, with the exception of vacant land, to which sanitary sewer connection is available but not used. This charge shall be set at an amount equal to the capital portion of the City's minimum sewer use charge. The resulting increase in this fee shall be phased in proportionately over a twenty-four-month period commencing upon the effective date of this section.
[Amended 8-28-1995 by Ord. No. 95-360]
J. 
Connection fee. Any person wishing to connect to the Bangor sewer system is required to pay a connection fee.
[Added 5-29-2013 by Ord. No. 13-156]
(1) 
This fee shall be updated every five years on the same schedule as the POTW’s federal and state permit renewal.
(2) 
The property owner must obtain a permit from the wastewater treatment plant and pay the calculated fee before connection to the public sewer system. The fee will be calculated and the amount conveyed within five business days from submission of the permit application.
(3) 
The average daily flow in gallons per day, as determined by the Uniform Plumbing Code, Maine Subsurface Wastewater Rules and other reliable sources, will be used to calculate the amount of the fee for all properties. A sewer connection fee schedule for various property uses based on these calculations will be provided with the connection permit application.
(4) 
Fee reduction and refund.
(a) 
A property owner may apply for a retroactive reduction of a sewer connection fee once one year has passed from the date of connection to the sewer system and not before. The property owner must submit the application for reduction within 30 days after the one-year anniversary date.
(b) 
For a reduction to be granted, the property owner must demonstrate the amount of wastewater entering the sewer system is less than the amount on which his/her sewer connection fee was based. A refund shall then be granted to the property owner based on the difference between the actual impact on the sewer system and the protected impact on the sewer system according to the sewer connection fee schedule.
(c) 
The reduction may be granted by the superintendent of the wastewater treatment plant. Appeal of the superintendent’s decision may be taken to the appropriate committee of the City Council in accordance with the procedure outlined in § 252-25G.

§ 252-25 Abatement of and discounts to sewer use charge.

[Amended 8-28-1995 by Ord. No. 95-359]
A. 
Abatements of sewer use charges may be granted by the Superintendent of the wastewater treatment plant upon application of a ratepayer, where the ratepayer can demonstrate that a loss of water occurred due to no fault of the ratepayer, his or her agents or employees. Abatement requests from commercial properties will be considered only if the loss of water was from building services (furnace, toilet, water heater, etc.), not from equipment used in the course of business, or unless otherwise allowed by § 252-25I of the Bangor Code. Ratepayers are responsible for exercising due care in the maintenance of their water and sewer systems to prevent water losses. For purposes of abatement, "due care" shall be defined as the normal and reasonable steps which would be taken by a prudent individual in operating and maintaining his or her sewer systems. A property whose owner has requested more than one abatement in any twelve-month period shall be subject to a property inspection by the Bangor Code Enforcement Division to verify compliance with the City of Bangor's Property Maintenance Code[1] and to ascertain whether due care is being exercised by the property owner. The inspection report, along with the abatement request, will be referred to the appropriate committee of the City Council. To be considered, a request for abatement must be made within 90 days of the billing date of the bill in question.
[Amended 2-12-2001 by Ord. No. 01-46; 6-24-2013 by Ord. No. 13-196]
[1]
Editor's Note: See Ch. 223, Property Maintenance Code.
B. 
Valid reasons for a request for abatement include, but are not necessarily limited to, unanticipated water pipe breakage, plumbing fixture malfunction, heating system malfunction and vandalism. Upon notice or knowledge of such circumstances, the ratepayer is responsible for taking appropriate and timely action to remedy the problem.
C. 
The Superintendent shall be responsible for researching the basis for the requested abatement in light of the due care standard established in Subsection A above. He or she shall make a record of the results of the investigation, which shall include an estimate of the amount of water lost. The estimate of water lost shall be based on a minimum of the previous four quarters of water consumption, if available, and consideration of seasonal water use patterns. This estimate of water loss shall be used to calculate the amount of the abatement should one be granted.
D. 
When an abatement is granted, the amount of the abatement shall be calculated based on the total sewer use charge for the estimated amount of water lost less the cost to convey and pump the estimated amount of water lost through the sewer system and treatment plant. The Superintendent shall be responsible for calculating, on an annual basis, the cost to convey and pump uncontaminated water through the sewer system and treatment plant. The basis for this calculation shall be the prior fiscal year's operation and maintenance costs of the system and plant.
E. 
When an abatement is granted, the Superintendent shall be responsible for taking the necessary steps to correct the appropriate billing records to reflect the abatement or to process a credit where the sewer use charge in question has been paid. Any outstanding balance owed the City by the property owner must be paid before the abatement is processed.
[Amended 2-24-2003 by Ord. No. 03-77; 6-24-2013 by Ord. No. 13-196]
F. 
Any abatement exceeding $3,000 must be reported to and confirmed by the appropriate committee of the City Council prior to final approval and the processing of a correction or credit.
[Amended 6-24-2013 by Ord. No. 13-196]
G. 
The Superintendent will submit a quarterly report to the appropriate Committee of the City Council summarizing processed abatements. The reports will be submitted in January, April, July and October.
[Added 6-24-2013 by Ord. No. 13-196[2]]
[2]
Editor’s Note: This ordinance also redesignated former Subsection G as Subsection H.
H. 
Any ratepayer who disagrees with the decision of the Superintendent to deny an abatement or with the amount of an abatement calculated by the Superintendent may, within 30 days of the date the ratepayer is notified of the Superintendent's decision, appeal the decision to the appropriate committee of the City Council. Appropriate City staff shall notify the ratepayer of the date, time and location of the meeting at which the appeal will be considered. In order for the appeal to be considered, the ratepayer and/or his or her representative must be present at the meeting. At the request of the ratepayer, consideration of the appeal may be postponed to a future meeting to be held within 60 days of the date established for the original meeting. Failure of the ratepayer to appear before the committee at the originally scheduled meeting or at a subsequent meeting called at the ratepayer's request shall result in the denial of the appeal. The decision of the appropriate committee of the City Council shall be final.
I. 
For the purposes of this section, "ratepayer" is defined as the owner or tenant of the property. The ratepayer must sign the abatement request.
[Added 6-24-2013 by Ord. No. 13-196[3]]
[3]
Editor’s Note: This ordinance also redesignated former Subsections H through J as Subsections J through L, respectively.
J. 
Abatements shall not be granted for water used for watering lawns or gardens, filling swimming pools or other outside water uses. Ratepayers may, however, at their own cost, install a secondary water meter that will measure only water used for outside water use purposes and/or only for purposes of filling indoor swimming pools.
[Amended 9-10-2001 by Ord. No. 01-343]
(1) 
Installation of the meter must be by a permit granted by the Superintendent or his or her designee. The installation must also be permitted by appropriate City staff to ensure that the meter meets all requirements of the Plumbing and Building Codes[4] and is used only to measure water actually used for outside water use purposes. The City Council may establish, by order, appropriate fees for this permit.
[4]
Editor's Note: See Ch. 81, Building Code, and Ch. 211, Plumbing Code.
(2) 
The City reserves the right to periodically inspect such meters to ensure continued compliance with the requirements of this Subsection H. Should it be determined that violations of this Subsection H have occurred, the permit for this secondary meter shall be revoked, and the ratepayer shall be subject to a fine equal to the amount the ratepayer would have been charged in sewer use fees since the date of installation of the secondary meter or for eight full quarters, whichever shall be the lesser.
(3) 
The ratepayer shall be responsible for reporting to the Superintendent or his or her designee the reading on the secondary meter. This report must be made no later than three working days after the date the ratepayer's primary water meter is normally read. Failure to report the reading in a timely matter will result in any adjustment appearing on the ratepayer's next quarterly bill subject to the provisions of § 252-25E, above. If adjustment is applied to the next quarterly bill, the adjustment will not exceed the quarterly sewer bill.
[Amended 2-24-2003 by Ord. No. 03-77]
(4) 
Where a secondary meter is installed, the ratepayer will be granted an abatement equal to the water metered through the submeter, in hundreds of cubic feet, multiplied by the current sewer rate, subject to the limitation stated in Subsection H above.
K. 
Any ratepayer which uses water in its end manufactured product, produced for the wholesale market, which is shipped from the ratepayer's facility may apply for an abatement of the sewer use fee equal to that portion of the water which does not reach the City's sewer system.
[Amended 6-9-2008 by Ord. No. 08-195]
(1) 
The applicant shall bear the burden of providing the necessary proof and documentation as to the amount of water used which does not enter into the sewer system. Adequate documentation must accompany the request for abatement and must clearly demonstrate the quantity of water used which does not enter into the sewer system. All such requests for abatement shall be made to the Superintendent, who shall be responsible for researching the basis for the abatement as well as the adequacy of the information provided.
(2) 
The Superintendent shall provide to the appropriate Council committee his or her recommendation as to whether the abatement should or should not be granted. The appropriate Council committee shall make the final determination as to whether the abatement shall or shall not be granted.
(3) 
All such abatements shall be limited to a period of no more than three years. At the end of this period, the ratepayer may apply for a new abatement. During the period in which an abatement is in effect and for one year following the expiration of the abatement, the City reserves the right to periodically inspect the ratepayer's premises and records to ensure that the ratepayer is in compliance with the abatement. Should it be determined that the information provided by the ratepayer is invalid, that changes have occurred in the ratepayer's processes which have the effect of increasing the amount of water reaching the sewer system or that more water is reaching the sewer system than reported by the ratepayer, the Superintendent may revoke the abatement, and the ratepayer shall be subject to a revised user charge equal to the full value of the abatement for the prior three-year period or the period in which a current or prior abatement was in effect, whichever is lesser.
(4) 
The amount of the abatement shall equal the full sewer use charge for water documented not to reach the sewer system less a quarterly charge established by order adopted by the City Council to recover expenses associated with administering the abatement.
L. 
Development discounts.
(1) 
The appropriate Council committee, at its sole discretion, may approve, subject to the following provisions, a sewer use charge discount for new businesses or existing businesses which expand. Such discounts will be available based on the number of full-time equivalent new jobs created by the business. The discount shall be limited to the capital portion of the sewer user charge. Any discounts granted shall be authorized for a period not to exceed five years and shall proportionately decrease each year. The sewer use discount shall be computed in accordance with the percentages and job creation categories shown on the following table.

Any business which has been granted a development discount must, on an annual basis, report to the Sewer Treatment Superintendent the number of new full-time equivalent jobs which continue to exist. Should this number either increase or decrease to the extent that the business receiving the discount moves from one job creation category to another, the discount shown in the computation table shown above for the number of new full-time equivalent jobs then reported shall apply for that year of the five-year discount period.
(3) 
In order to be eligible for such discount, the business seeking it must be located within the corporate boundaries of the City of Bangor, be subject to the payment of full municipal property taxes and have made a significant investment in an existing or new facility. A "significant investment" shall be defined as the construction of a new facility or the investment of an amount equal to at least 20% of the preexisting assessed value of an existing facility in renovation, expansion or equipment costs associated with the location or expansion of the business. This discount shall not be available to businesses which have purchased other existing businesses, unless additional new employment is created or the business purchased has not been in operation for a minimum period of six months. It shall also not be available to businesses which recall laid-off workers or increase employment due to a prior reduction in force, unless such layoffs or reductions have been in effect for a period of more than one year.
