A. Wastewater Users: It is unlawful to discharge sewage, industrial wastes or other wastes to any sewer within the jurisdiction of the city and/or to the POTW without having first complied with the terms of this chapter. All existing users who discharge industrial wastes or other wastes to the POTW shall comply with all terms of this chapter within ninety (90) days of being notified by the city. All users proposing to discharge waste to the POTW shall comply with all terms of this chapter prior to discharging waste to the POTW.
B. Pretreatment Discharge Permit: No user shall discharge wastewater into the POTW without first obtaining a pretreatment discharge permit from the city. Any violation of the terms and conditions of a pretreatment discharge permit shall be deemed a violation of this chapter and shall subject the pretreatment discharge permittee to the sanctions set out in this chapter. Obtaining a pretreatment discharge permit does not relieve a permittee of its obligation to comply with all federal and state pretreatment standards or requirements, or with any other requirements of federal, state and local law. The wastewater division head may require other users, including liquid waste haulers, to obtain pretreatment discharge permit (as necessary) to carry out the purposes of this chapter. The city reserves the right not to issue a pretreatment discharge permit if the applicant cannot meet the pretreatment discharge requirements. Any pretreatment discharge permit shall expressly state that a violation of this chapter, or a pretreatment discharge permit, or order issued under this chapter, or any other pretreatment standard or requirement, will make the permittee liable for any expense, loss or damage to the city wastewater system or POTW.
C. Pretreatment Discharge Permit Requirements:
1. Industrial Waste Acceptance Permit: All existing users and users proposing to connect to, or to discharge sewage, industrial wastes and other wastes to, the POTW shall obtain a pretreatment discharge permit. The pretreatment discharge permit shall be issued for a specified time period, not to exceed five (5) years. A pretreatment discharge permit may be issued for a period less than five (5) years at the discretion of the city. Each permit will indicate a specific date upon which it will expire.
2. Disclosure Forms: Prior to the city granting a pretreatment discharge permit, the user shall complete and file with the city a disclosure declaration in the form prescribed by the city. Existing users shall file disclosure forms within thirty (30) days of being notified by the city. Proposed new users shall file their disclosure forms at least ninety (90) days prior to connecting to the POTW. The disclosure to be made by the user shall be on written forms provided by the city and shall require the following information:
a. Disclosure of the name of the facility, the address and the location of the facility, and the owner's and operator's name.

3. Incomplete, Inaccurate Applications: Incomplete or inaccurate applications will not be processed and will be returned to the user for revision.
4. Signatory And Certification Requirement: All pretreatment discharge permit applications and user reports must be signed by an authorized representative of the user.
D. Pretreatment Discharge Permit Decisions: The wastewater division head, or his designee, will evaluate the complete disclosure form and data furnished by the user and may require additional information, including an inspection of the premises. Within thirty (30) days of receipt of a complete wastewater discharge permit application, and after full evaluation of the information provided, and if necessary, a complete inspection of the premises, the wastewater division head, or his designee, will determine whether or not to issue a wastewater discharge permit, and type of permit to be issued. After acceptance of the data furnished, the city shall notify the user of the city's acceptance or denial thereof. Where determined necessary by the wastewater division head, or his designee, a pretreatment discharge permit may be issued setting forth limitations of various waste strengths as addressed under this chapter.
E. Pretreatment Discharge Permit Conditions:
1. Revocation Of Pretreatment Discharge Permit: The pretreatment discharge permit issued to a user by the city may be revoked for, but not limited to, the following reasons:
a. Failure to notify the city of significant changes to the wastewater prior to the changed discharge;
b. Failure to provide notification to the city of changed conditions;
c. Misrepresentation or failure to fully disclose all relevant facts in the pretreatment discharge permit application;
d. Falsifying self-monitoring reports;
e. Tampering with monitoring equipment;
f. Failure to meet discharge limitations;
g. Failure to pay fines;

e. Violation of any terms or conditions of the wastewater discharge permit;
f. Misrepresentations or failure to fully disclose all relevant facts in the pretreatment discharge permit application or in any required reporting or inspection;
g. Revision of, or grant of, a variance from categorical pretreatment standards pursuant to 40 CFR 403.13;
h. To correct typographical or other errors in the wastewater discharge permit; or
i. To reflect a transfer of the facility ownership and/or operation to a new owner/operator.
4. Duty To Reapply For Pretreatment Discharge Permit: Within thirty (30) days of the permit expiration, the user shall reapply for reissuance of the pretreatment discharge permit on a form provided by the city. A user, whose existing pretreatment discharge permit has expired and who has submitted its reapplication in the time period specified herein, shall be deemed to have an effective pretreatment discharge permit until the city issues or denies the new pretreatment discharge permit. A user, whose existing pretreatment discharge permit has expired and who has failed to submit its reapplication in the time period specified herein, shall be deemed to be discharging without a pretreatment discharge permit.
5. Severability: The provisions of a pretreatment discharge permit are severable, and if any provision of the pretreatment discharge permit, or the application of any provision of the permit to any circumstance is held invalid, the application of such provision to other circumstances, and the remainder of the permit shall not be affected thereby.
6. Property Rights: The issuance of a pretreatment discharge permit does not convey any property rights in either real or personal property, or any exclusive privileges, nor does it authorize any infringement of federal, state or local regulations, nor any action, at law or in equity, for invasion of personal rights for violation of any federal, state or constitutional protections.
7. Permit Holders Outside City Limits: All users outside the city limits who discharge sewage, industrial wastes or other wastes to any sewer within the jurisdiction of the city and/or to the POTW shall be subject to the wastewater pretreatment use regulations as users inside the city limits and at a minimum any other use regulation set forth in an agreement between the city and the permit holder.
F. Pretreatment Discharge Permit Appeals:
1. Any user may appeal to the city council, within thirty (30) days of its issuance or denial, subject to the following conditions:
a. Failure to submit a timely petition for review shall be deemed to be a waiver of the administrative appeal.
b. In its appeal petition, the appellant must indicate which pretreatment discharge permit provisions are objected to, the reasons for this objection, and the alternative condition, if any, it seeks to place on the pretreatment discharge permit.
c. The issuance or denial of the pretreatment discharge permit shall not be stayed pending the appeal.
2. The city council may affirm, modify or reverse a decision issuing or denying a pretreatment discharge permit. The city council decision shall be considered final administrative action for purposes of judicial review. After a final administrative appeal has been brought before the city, an aggrieved party seeking judicial review of such final administrative pretreatment discharge permit decision must do so by filing a petition for review with the district court for Blaine County within the state of Idaho.
G. Reporting Requirements For Users:
1. Compliance Date Report:
a. Within thirty (30) days following commencement of the introduction of wastewater into the POTW by a new source or new user, this new user shall, upon request of the wastewater division head, submit to the city a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge, and the average and maximum daily flow in gallons.
b. In the case of categorical users, the flows and pollutant concentrations (or mass) of the waste streams from processes regulated under categorical pretreatment standards must be reported separately. This report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional O&M and/or pretreatment is necessary to bring the user into compliance with applicable pretreatment standards or requirements.
c. For users subject to equivalent mass or concentration limits established by the city in accordance with procedures established in 40 CFR 403.6(c), this report shall contain a reasonable measure of the user's long term production rate. For all other users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of production), this report shall include the user's actual production during the appropriate sampling period.
d. All compliance reports shall be signed by an authorized representative of the user.
2. Periodic Compliance Reports:
a. Any user that is required to have a pretreatment discharge permit and/or who is otherwise subject to any applicable pretreatment standard set forth in this chapter, after the compliance date of such pretreatment standard, or in the case of a new user, after commencement of discharge to the city, shall submit to the city during the months of June and December, unless required more frequently by the wastewater division head, a report indicating the nature and concentration of prohibited or regulated substances in the effluent which are limited by the pretreatment standards hereof and/or as prescribed within the pretreatment discharge permit. In addition, this report shall include a record of all measured or estimated average and maximum daily flows during the reporting period as set forth in subsection G1 of this section.
b. Reports of users shall contain all results of sampling and analysis of the discharge, including the flow and the nature and concentration of regulated pollutants, or production and mass where required by the city. The frequency of monitoring by the user shall be as prescribed by wastewater division head, shall occur not less than twice a year, unless the city agrees to sample instead. All analyses shall be performed in accordance with procedures established by the city pursuant to section 304(g) of the act and contained in 40 CFR part 136, and subsections K and L of this section, or with any other test procedures approved by the wastewater division head. The record of all flow measurements (average and maximum) taken at the designated sampling locations shall include any additional information required by this chapter and/or the pretreatment discharge permit. Both daily maximum and average concentration (or mass, where required) shall be reported.
c. Sampling shall be performed in accordance with the techniques approved by the wastewater division head and this chapter and shall be representative of wastewater discharges during the reporting period. Where 40 CFR part 136 does not include sampling or analytical techniques for the pollutants in question, or where the wastewater division head determines that the part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical methods, or any other sampling and analytical procedures, including procedures suggested by the wastewater division head.
d. Flows shall be reported on the basis of actual measurement; provided, however, that the city may accept reports of average and maximum flows estimated by verifiable techniques if the wastewater division head determines that an actual measurement is not feasible.
e. The wastewater division head, for good cause shown, and considering such factors as local high or low flow rates, holidays, budget cycles, or other extenuating factors, may authorize the submission of such reports on months other than those specified above.
f. The city may require self-monitoring by the user or, if requested by the user, may agree to perform the periodic compliance monitoring needed to prepare the periodic compliance report required under this section. If the city agrees to perform such periodic compliance monitoring, it may charge the user for such monitoring, based upon the costs incurred by the city for sampling and analyses. Any such charges shall be added to the normal sewer charge and shall be payable as part of the sewer bills. The city is under no obligation to perform periodic compliance monitoring for a user.
g. A certification statement signed by an authorized representative of the user is required as a part of the periodic compliance reports.
3. Notification Of Significant Production Changes: Any user operating under a pretreatment discharge permit incorporating equivalent mass or concentration limits shall notify the city within two (2) 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 providing a notice of such anticipated change will be required to comply with the existing limits contained in its pretreatment discharge permit.
4. Notice Of Potential Problems, Including Accidental Spills And/Or Slug Loadings: Any user shall notify the city immediately of all discharges that could cause problems to the POTW, including any slug loadings as defined in sections 13.05.010 through 13.05.040 of this chapter. The notification shall include the concentration and volume of the discharge. Corrective action, including steps being taken to reduce any adverse impact should also be noted during the notification. Any user who discharges a slug (or slugs) of prohibited materials shall be liable to the city for any expense, loss or damage to the POTW, in addition to the amount of any fines imposed under state or federal law.
5. Noncompliance Reporting: If sampling performed by a user indicates a violation, the user shall notify the city within twenty four (24) hours of becoming aware of the violation. The user shall also repeat the sampling within five (5) days and shall submit the results of the repeat analysis to the city within thirty (30) days after becoming aware of the violation, except the user is not required to resample if the city performs sampling at the user facility between the time when the user performs its initial sampling and the time when the user receives the results of this sampling.
6. Notification Of Changed Discharge: All users shall promptly notify the city in advance of any substantial change in the volume or character of pollutants in their discharge, including significant manufacturing process changes, pretreatment modifications, and the listed or characteristic hazardous wastes for which the user has submitted initial notification under 40 CFR 403.12(p).
7. Notification Of Hazardous Waste:
a. Existing users that are discharging fifteen (15) kilograms of hazardous wastes as defined in 40 CFR 261 (listed or characteristic wastes) in a calendar month, or any facility which generates any amount of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e) are required to provide a onetime notification in writing to the city and the EPA regional waste management division director. Any existing user exempt from this notification, shall comply with the requirements contained herein within thirty (30) days of becoming aware of a discharge of fifteen (15) kilograms of hazardous wastes in a calendar month or the discharge of acutely hazardous wastes to the city sewer system. Such notification shall include:
(1) The name of the hazardous waste as set forth in 40 CFR part 261;
(2) The EPA hazardous waste number; and
(3) The type of discharge (continuous, batch or other).
b. If a user generates more than one hundred (100) kilograms of such waste per calendar month to the sewer system, the notification shall also contain the following information to the extent it is known or readily available to the user:
(1) An identification of the hazardous constituents contained in the wastes;
(2) An estimation of the mass and concentration of such constituents in the waste streams discharged during that calendar month; and
(3) An estimation of the mass of constituents in the waste streams expected to be discharged during the following twelve (12) months.
c. These notification requirements do not apply to pollutants already reported under the self-monitoring requirements.
d. Whenever the EPA publishes final rules identifying additional hazardous wastes or new characteristics of hazardous waste, a user shall notify the city of the discharge of such a substance within ninety (90) days of the effective date of such regulations.
e. In the case of any notification made under this subsection, a user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
H. Reports From Unpermitted Users: All others not required to obtain a pretreatment discharge permit pursuant to this chapter shall provide appropriate access for sampling, flow measurements and analysis to the city as the wastewater division head, or his or her designee, may require. Users subject to the reporting requirements of this chapter shall retain and make available for inspection and copying all records of information obtained pursuant to any monitoring activities required by this chapter, and any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements. Records shall include the date, exact place, method and time of sampling and the name of the person(s) taking the samples; the dates analyses were performed; and the name of the person who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three (3) years. This period shall be automatically extended for the duration of any litigation concerning the user or POTW, or where the user has been specifically notified of a longer retention period by the wastewater division head.
I. Compliance Schedules For Meeting Applicable Pretreatment Standards: The compliance schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans, executing contract for major components, commencing construction, completing construction, etc.). No increment referred to above shall exceed nine (9) months.
J. Monitoring Facilities: The city may require the user to install monitoring equipment as necessary.
1. Each user shall provide and operate, at the user's own expense, a monitoring facility to allow inspection, sampling, and flow measurement of each sewer discharge to the sewer.
2. Each monitoring facility shall be situated on the user's premises, except where such location would be impractical or cause undue hardship on the user. The city may permit the monitoring facility to be constructed in the public street or sidewalk area providing that the facility is located so that it will not be obstructed by landscaping or parked vehicles.
3. There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user. All devices used to measure wastewater flow and quality shall be calibrated at a frequency determined by the city to ensure their accuracy.
4. All monitoring facilities shall be constructed and maintained in accordance with all applicable local construction standards and specifications as well as local zoning and land use ordinances. Construction shall be completed within one hundred twenty (120) days of receipt of the permit by the user, unless a compliance schedule has been approved by the wastewater division head.
K. Compliance Monitoring:
1. Inspection And Sampling: The city shall have the right to obtain consent to enter the facilities of any user to ascertain whether the purpose of this chapter, and any pretreatment discharge permit, or order issued hereunder, is being met and whether the user is complying with all requirements thereof. Users shall allow the city ready access to all parts of the premises for the purposes of inspection, sampling, records examination and copying and the performance of any additional duties.
2. Search Warrants: If the wastewater division head, or his or her designee, has been refused access to a building, structure or property, or any part thereof, and is able to demonstrate probable cause to believe that there may be a violation of this chapter, or that there is a need to inspect as part of a routine inspection program of the city designed to verify compliance with this chapter or any pretreatment discharge permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the wastewater division head, or his or her designee, shall seek issuance of search and/or seizure warrant from the district court in and for the county of Blaine. Such warrant shall be served by the wastewater division head, and his or her designee, in the company of a uniformed police officer of the city or local county.
3. Vandalism: No person shall wilfully or negligently break, damage, destroy, uncover, deface, tamper with or prevent access to any structure, appurtenance or equipment, or other part of the POTW. Any person found in violation of this requirement shall be subject to the sanctions set out in this chapter.
L. Sampling And Analytical Requirements:
1. Sampling Requirements For Users:
a. A minimum of four (4) grab samples must be used for pH, cyanide, total phenols, fats, oils and greases, sulfide and volatile organics. The wastewater division head will determine on a case by case basis whether the user may be able to composite the individual grab samples. For all other pollutants, twenty four (24) hour composite must be obtained through flow proportional composite sampling techniques where feasible. The wastewater division head may waive flow proportional composite sampling for any user that demonstrates that flow proportional sampling is infeasible. In such cases, samples may be obtained through time proportional composite sampling techniques, or through a minimum of eight (8) grab samples, where the user demonstrates that this will provide a representative sample of the effluent being discharged.
b. Samples should be taken immediately downstream from pretreatment facilities if such exist, or immediately downstream from the regulated or manufacturing process if no pretreatment exists, or as determined by the wastewater division head and contained in the user's pretreatment discharge permit.
(1) For categorical users, if other wastewaters are mixed with the regulated wastewater prior to pretreatment, the user should measure the flows and concentrations necessary to allow use of the combined wastes formula of 40 CFR 403.6(e) in order to evaluate compliance with the applicable pretreatment standards.
(2) For other SIUs, for which the city has adjusted its local limits to factor out dilution flows, the user should measure the flows and concentrations necessary to evaluate compliance with the adjusted pretreatment standard(s).
c. All sample results shall indicate the time, date and place of sampling and methods of analysis and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges from the user. If a user samples more frequently than what was required in its pretreatment discharge permit, it must submit all results of sampling and analysis of the discharge as part of a self-monitoring report during the reporting period.
2. Analytical Requirements: All pollutant analyses, including sampling techniques, shall be performed in accordance with the techniques prescribed in 40 CFR part 136, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR part 136 does not contain sampling or analytical techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by the EPA.
M. Pretreatment Facilities:
1. Detailed plans showing the pretreatment facilities shall be submitted to the city for review, and must be acceptable to the city before construction of the facility. The review of such plans shall in no way relieve the user from the responsibility of modifying its facility as necessary to produce an effluent acceptable to the city under the provisions of this chapter.
2. Within a reasonable time after the completion of the wastewater pretreatment facility, the user shall furnish its operation and maintenance procedures for the wastewater division head to review.
3. Any subsequent, significant changes to the pretreatment facility or its method of operation shall be reported to and accepted by the wastewater division head prior to the user's initiation of the changes.
N. TTO Reporting: Categorical users which are required by EPA to eliminate and/or reduce the levels of toxic organics (TTOs) discharged into the sewer system must follow the categorical pretreatment standards for that industry. Those users must also meet the following requirements:
1. Categorical users must sample, as part of the application requirements, for all the organics listed under the TTO limit (no exceptions); and
2. The user elects to develop a solvent management plan in lieu of continuously monitoring for TTO, the user must routinely submit a certification statement as part of its self-monitoring report that there has been no dumping of concentrated toxic organic into the wastewater and that it is implementing a solvent management plan as approved by the city. (Ord. 1086 §§ 1 - 5, 2011; Ord. 1070 § 1, 2010; Ord. 741 § 1, 1999)
