More specifically, no industrial user shall discharge any waste stream with a closed cup flash point of less than 60 degrees Celsius (140 degrees Fahrenheit) using the test methods specified in 40 CFR Section 261.21. The Superintendent may require industrial users with the potential to discharge flammable, combustible or explosive substances to install and maintain an approved combustible gas detection meter or explosion hazard meter. No two successive readings on an explosion hazard meter at the point of discharge shall be more than five percent, nor any one reading more than 10 percent, of the lower explosive limit (LEL) of the meter.
(4) 
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.
(5) 
Garbage that has not been properly ground.
(6) 
Ashes, cinders, sand, mud, straw, shavings, wood, metal, glass, rags, feathers, tar, plastics, paunch manure, butchers' offal or any other solid or viscous substances capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewerage system or the wastewater treatment plant.
(7) 
Waters or wastes having a pH lower than 5.0 or having any other corrosive property capable of causing damage or posing hazards to the structures, equipment or personnel of the sewage works.
(8) 
Solid or viscous substances which may cause obstruction in the sewage system or otherwise cause interference to the POTW.
(9)

(10) 
Any pollutant, including oxygen demanding pollutants (CBOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause pass through or interference with the POTW.
(11) 
Any waters or wastes containing suspended solids of such character and quantity that unusual provision, attention or expense would be required to handle such materials at the wastewater treatment plant, its pumping stations or other facilities.
(12) 
Stormwater drainage from ground resulting in infiltration and inflow (I&I) through the industrial user's service line(s), surface, roof drains, catch basins, unroofed area drains (e.g., commercial car washing facilities) or any other source unless otherwise approved by the Superintendent. Specifically prohibited is the 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 the city's wastewater collection system. No person shall connect or discharge water from underground drains, sump pump discharges, natural springs and seeps, water accumulated in excavation or grading or any other water associated with construction activities.
(13) 
A slug discharge as defined in AMC § 13.10.020.
(14)

(21) 
Any pollutant or wastewater containing pollutants with UV (254 nm) absorbing substances which causes interference with UV disinfection at the treatment plant.
(C) 
Wastes prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW except as authorized by an industrial user permit and/or this chapter. If the industrial user has a pretreatment facility, all floor drains located in process or materials storage areas must discharge to the industrial user's pretreatment facility or to sumps or tanks that do not have the potential for a discharge to the POTW before connecting with the POTW. The city may require other industrial users to contain or collect wastewater from floor drains to protect the POTW and meet the objectives of this chapter.
(D) 
Specific Discharge Limitations. It shall be unlawful for any significant industrial user or other permitted nonsignificant industrial user to discharge, deposit, cause, or allow to be discharged any waste or wastewater which fails to comply with the limitations imposed by this section.
(1) 
Dilution is prohibited as a substitute for treatment and shall be a violation of this chapter. Except where expressly authorized to do so by an applicable pretreatment standard or requirement, no industrial user shall ever increase the use of process water, or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a pretreatment standard or requirement. The city may impose mass limitations on industrial users which are using dilution to meet applicable pretreatment standards or requirements or in other cases where the imposition of mass limitations is appropriate.

Any person who discharges industrial wastes into the city's sewerage system, either directly or indirectly, shall, upon the written request of the Board of Public Works, fill out and file with the city within 90 days an industrial waste questionnaire to be furnished by the city, in which he or she shall set out the quantity and characteristics of the wastes discharged into the city's sewerage system. Similarly, any person desiring to establish a new connection to a public sewer for the purpose of discharging industrial wastes may be required to fill out and file such a questionnaire which shall include actual or predicted data relating to the quantity and characteristics of the wastes to be discharged.
(C) 
When special circumstances such as the size or complexity of his or her sewage disposal problem would make complying with the time schedule cited above an unreasonable burden on the person, an extension of time, not to exceed 90 days, may be granted by the Board of Public Works upon presentation of a proper application.
(Ord. 1598-2018; Ord. 789, 1990; Ord. 692, 1986; Code 2000 § 51.051; Code 1981 § 13.24.160)
(A) 
Any person discharging industrial wastes into a public sewer, either directly or indirectly, may be required by the Board of Public Works, upon recommendation of the Superintendent, to construct and maintain at his or her own expense one or more control manholes at a specified location or locations to facilitate the observation, measurement and sampling of his or her wastes. Such manholes shall be constructed in accordance with the standards and specifications of the city. The Board may also require the person to install and maintain in any such manhole at the person's expense an approved volume-measuring device.
(B) 
Plans for the installation of control manholes and related equipment must be approved by the Board of Public Works, upon the recommendation of the Superintendent and the Sewer Engineer, before construction is begun.
(Ord. 1598-2018; Ord. 789, 1990; Ord. 692, 1986; Code 2000 § 51.052; Code 1981 § 13.24.170)

Penalty: See AMC § 13.10.610.
(A) 
Sample Collection. Compliance determinations with respect to prohibitions and limitations in this chapter may be made based on either grab or composite samples of wastewater as specified by the city. Such samples shall be taken at a point or points which the city determines to be suitable for obtaining a representative sample of the discharge. Composite samples may be taken over a 24-hour period, or over a longer or shorter time span, as determined by the city to meet specific circumstances.
(B) 
Sample Type. Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report and based on data that is representative of conditions occurring during the reporting period.
(1) 
Except as indicated in subsections (B)(2) and (3) of this section, the industrial user must collect representative wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is required by the city. Where time-proportional composite sampling or grab sampling is authorized by the city, the samples must be representative of the permitted discharge.
(2) 
Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: For cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composited samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the city, as appropriate. In addition, grab samples may be required to show compliance with instantaneous local limits, including pH.
(3) 
For sampling required in support of baseline monitoring and 90-day compliance reports required in AMC § 13.10.300, a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds for facilities for which historical representative sampling data do not exist. Where historical data are available, the city may authorize a lower minimum. For the reports required by AMC § 13.10.300, the industrial user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.
(C) 
Analytical Requirements. All pollutant analyses, including sampling techniques, to be submitted as part of an industrial discharge permit application, report, permit or other analyses required under this chapter shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto, 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, or where the EPA determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the city or other parties approved by the EPA.
(D) 
Records shall include for all samples:
(1) 
The date, exact place, method, and time of sampling and the name of the person(s) taking the samples;
(2) 
The date(s) analyses were performed;
(3) 
Who performed the analyses;
(4) 
The analytical techniques/methods used, including method detection limits and QA/QC sample results;
(5) 
Calibration and maintenance records;
(6) 
All chain-of-custody records; and
(7) 
The results of such analyses.
(Ord. 1598-2018; Ord. 822, 1992; Ord. 789, 1990; Ord. 780, 1989; Ord. 692, 1986; Code 2000 § 51.053; Code 1981 §§ 13.24.180, 13.24.190 and 13.24.200)
The authority reserves the right to amend this chapter and its terms and conditions in order to assure compliance with applicable laws and regulations. Categorical pretreatment standards as promulgated by the Environmental Protection Agency (EPA) pursuant to the Act shall be met by all dischargers regulated under such standards unless the POTW allows for the application of a removal credit allowance as defined at 40 CFR Section 403.7.
(Ord. 1598-2018; Ord. 1507-2015; Ord. 692, 1986; Code 2000 § 51.054; Code 1981 § 13.24.220)
The authority may seek to terminate the wastewater treatment services to any discharger which:
(A) 
Fails to factually report the wastewater constituents and characteristics of its discharge;
(B) 
Fails to report significant changes in wastewater constituents or characteristics;
(C) 
Refuses reasonable access to the discharger's premises by representatives of the authority for the purpose of inspection or monitoring; or
(D) 
Violates the conditions of this article or any final judicial order entered with respect to provisions of this article.
(Ord. 1598-2018; Ord. 692, 1986; Code 2000 § 51.055; Code 1981 § 13.24.230)
(A) 
Compliance Schedule. Any noncategorical industry which is not in compliance with the city's limitations must develop a compliance schedule during which time the industry must meet the city's standards. The schedule should contain increments of progress (hiring engineers, starting construction and the like) which correspond to specific dates for their completion. These represent major events leading to the operation of pretreatment equipment to meet the city's pretreatment standards. All industrial users subject to these conditions must submit a progress report to the city no later than 14 days following each date in the compliance schedule. This report must include whether it complied with the increment of progress to be met on that date, the reason for delay if the date was not met, and the steps being taken to return to compliance. In no event can more than nine months elapse between progress reports.
(B) 
Compliance Schedule Reports (Categorical Industries). These reporting conditions apply to the compliance schedule required in 40 CFR Part 403.12(b)(7). This schedule is necessary whenever an industrial user is not meeting categorical pretreatment standards at the time of promulgation of that standard. The schedule contains increments of progress (hiring an engineer, completing plans, commencing construction, completing construction and the like) which correspond to specific dates for their completion. These represent major events leading to the construction and operation of additional pretreatment required for the industrial user to meet the applicable categorical pretreatment standards.
(C) 
Monthly Reports. This requirement calls for the submission of all notices and self-monitoring reports from industrial users that are necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements. These reports will normally be required on a monthly basis.
(D) 
Baseline Report.
(1) 
Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision made on a category, whichever is later, existing industrial users subject to such categorical pretreatment standards and currently discharging to or scheduled to discharge to a POTW will be required to submit to the control authority a report containing the information listed in 40 CFR Sections 403.12(b)(1) through (b)(7).
(2) 
Upon promulgation of a categorical pretreatment standard, the control authority (either EPA, state or POTW) will provide the appropriate 12(b) forms for distribution to the industrial users who are affected by the promulgated standard. The industrial users are then required to submit the completed report to the control authority.
(E) 
Compliance Date Report.
(1) 
Within 90 days following the date for final compliance with an applicable pretreatment standard, any industrial user subject to those standards must submit to the control authority a report indicating the nature and concentration of all pollutants in the discharge generated from the regulated process which are limited by categorical pretreatment standards.
(2) 
The report must also state whether applicable standards are being met on a consistent basis and, if not, what additional O & M and/or pretreatment is necessary to bring the discharge into compliance. This statement should be signed by an authorized representative of the industrial user.
(F) 
Periodic Reports on Continued Compliance. Any discharger subject to an applicable pretreatment standard must submit to the authority during the months of June and December, or more frequently if required by the authority, following the final compliance date of that pretreatment standard, a report indicating the nature and concentration of prohibited or regulated substances in the discharge which are limited by the categorical pretreatment standards. In addition, this report must include a record of all measured or estimated average and maximum daily flows during the reporting period. Flows are to be reported on the basis of actual measurement, except, where cost or feasibility considerations justify, the authority may accept reports of average and maximum flows estimated by verifiable techniques. The authority, considering such factors as local high or low flow rates, holidays, budget cycles or other extenuating factors, may authorize submission of the reports on months other than those specified above.
(G) 
Signatory Certification. All reports and other submittals required to be submitted to the city shall include the following statement and signatory requirements:
(1) 
The authorized representative of the industrial user signing any application, questionnaire, any report or other information required to be submitted to the city must sign and attach the following certification statement with each such report or information submitted to the city:
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 ensure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system or the 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 a fine and imprisonment for knowing violations.
(2) 
If the authorized representative is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the company, a new authorization satisfying the requirements of AMC § 13.10.020 must be submitted to the city prior to or together with any reports to be signed by an authorized representative.
(Ord. 1598-2018; Ord. 692, 1986; Code 2000 § 51.056; Code 1981 §§ 13.24.240, 13.24.250, 13.24.260, 13.24.270, 13.24.280 and 13.24.290)
(A) 
Whenever it shall be necessary for the purposes of this chapter, the city may enter upon any industrial user's facility, property, or premises subject to this chapter that is located or conducted or where records are required to be kept for the purposes of:
(1) 
Performing all inspection, surveillance and monitoring procedures necessary to determine, independent of information supplied by industrial users, compliance or noncompliance with applicable pretreatment standards and requirements by an industrial user. Compliance monitoring and inspection shall be conducted at a frequency as determined by the city and may be announced or unannounced;
(2) 
The city may use a camera to photograph areas of the facility as deemed necessary for carrying out the duties of the industrial pretreatment program including, but not limited to, documentation of the industrial user's operations and compliance status and for reinforcement of required written reports. The industrial user shall be allowed to review copies of photographs for confidentiality claims;
(3) 
Examining and copying any records required to be kept under the provisions of this chapter or of any other local, state or federal regulation;
(4) 
Inspecting any monitoring equipment or method, pretreatment system equipment and/or operation;
(5) 
Sampling any discharge of wastewater into POTW; and/or
(6) 
Inspecting any production, manufacturing, fabricating or storage area where pollutants, regulated under this chapter, could originate, be stored, or be discharged to the POTW.
(B) 
The occupant of such property or premises shall render all proper assistance in such activities. Where an industrial user has security measures in place which require proper identification and clearance before entry into its premises, the industrial user shall make necessary arrangements with its security personnel so that authorized representatives of the city will be permitted to enter without delay to perform their specified functions.
(C) 
The Superintendent and other duly authorized agents and employees of the city are entitled to enter all private properties through which the city holds a negotiated easement.
(D) 
Failure to Allow Entry or Unreasonable Delays.
(1) 
In the event the city or other duly authorized representative of the city is refused admission or unreasonably delayed, enforcement action may result as allowed for under this chapter, including termination of discharge of wastewater to the POTW.
(2) 
If the city has been refused access to a building, structure or property or any part thereof, and/or if the city has demonstrated probable cause to believe that there may be a violation of the industrial discharge permit or this chapter, or that there is a need to inspect as part of an inspection program designed by the city to verify compliance with the industrial discharge permit or any order issued hereunder, or to protect the overall public health, safety, and welfare of the community, then the city shall seek a search and/or seizure warrant describing the specific location subject to the warrant.
(Ord. 1598-2018; Ord. 692, 1986; Code 2000 § 51.057; Code 1981 § 13.24.300)
(A) 
All industrial users shall retain, and make available for inspection and copying, all records, reports, monitoring or other data, applications, permits and all other information and documentation required by this chapter including documentation associated with best management practices.
(B) 
Industrial users shall retain such records and shall keep such records available for inspection for at least three years. This record-keeping period shall be extended automatically for the duration of any litigation concerning the industrial user's compliance with any provision of this chapter, or when the industrial user has been specifically and expressly notified of a longer records retention period by the Superintendent.
(Ord. 1598-2018; Ord. 692, 1986; Code 2000 § 51.058; Code 1981 § 13.24.330)
(A) 
All records, reports, data or other information supplied by any person or industrial user as a result of any disclosure required by this chapter or information and data from inspections shall be available for public inspection except as otherwise provided in this section, 40 CFR Section 403.14 and the Indiana Open Records Act (IC 5-14-3 et. seq.).
(B) 
These provisions shall not be applicable to any information designated as a trade secret by the person supplying such information. Materials designated as a trade secret may include, but shall not be limited to, processes, operations, style of work or apparatus or confidential commercial or statistical data. Any information and data submitted by the industrial user which is desired to be considered a trade secret shall have the words, "Confidential Business Information" stamped on each page containing such information. The industrial user must demonstrate to the satisfaction of the city that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets of the industrial user.
Information designated as a trade secret pursuant to this section shall remain confidential and shall not be subject to public inspection. Such information shall be available only to officers, employees or authorized representatives of the city charged with implementing and enforcing the provisions of this chapter and properly identified representatives of the U.S. Environmental Protection Agency and the Indiana Department of Environmental Management.
Effluent data from any industrial user, whether obtained by self-monitoring, monitoring by the city or monitoring by any state or federal agency, shall not be considered a trade secret or otherwise confidential. All such effluent data shall be available for public inspection.
