1. 
Any (significant industrial) user subject to a pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the Superintendent during the months of June and December, unless required more frequently in the pretreatment standard or by the Superintendent, a report indicating the nature and concentration, of pollutants in the effluent which are limited by such pretreatment standards. In addition, this report shall include a record of all daily flows which during the reporting period exceeded the average daily flow reported in Subsection (A) of this Section. At the discretion of the Superintendent and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the Superintendent may agree to alter the months during which the above reports are to be submitted.
2. 
The Superintendent may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by Subparagraph (1) of this Subsection shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user. These reports shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where requested by the Superintendent, of pollutants contained therein which are limited by the applicable pretreatment standards. The frequency of monitoring shall be prescribed in the applicable pretreatment standard. All analysis shall be performed in accordance with procedures established by the Administrator pursuant to Section 304(q) of the Act and contained in 40 CFR, Part 136 and amendments thereto or with any other test procedures approved by the Administrator. Sampling shall be performed in accordance with the techniques approved by the Administrator.
3. 
In cases where the pretreatment standard requires compliance with a Best Management Practice (BMP) or pollution prevention alternative, the user must submit documentation required by the Superintendent or the pretreatment standard necessary to determine the compliance status of the user.
4. 
If a user subject to the reporting requirement in this Section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Superintendent, using the procedures prescribed in Section 710.160(B)(8) of this Chapter, the results of this monitoring shall be included in the report.
5. 
Annual Certification For Non-Significant Categorical Industrial Users. A facility determined to be a non-significant categorical industrial user by the Superintendent pursuant to Sections 1.4GG(3) and 4.7 C [Note: See 40 CFR Section 403.3(v)(2)] must annually submit the following certification statement signed in accordance with the signatory requirements in Section 1.4 C [Note: See 40 CFR Section 403.120(1)]. This certification must accompany an alternative report required by the Superintendent:
Based on my inquiry of the person or persons directly responsible for managing compliance with the categorical pretreatment standards under 40 CFR _____, I certify that, to the best of my knowledge and belief that during the period from __________, _____ to _____, _____ [months, days, year]:
(a)
The facility described as ______________ [facility name] met the definition of a non-significant categorical industrial user as described in 1.4 GG (3);
(b)
The facility complied with all applicable pretreatment standards and requirements during this reporting period; and
(c)
The facility never discharged more than 100 gallons of total categorical wastewater on any given day during this reporting period. This compliance certification is based on the following information.
6. 
Certification of Pollutants Not Present. Users that have an approved monitoring waiver based on Section 710.150(B)(7) must certify on each report with the following statement that there has been no increase in the pollutant in its wastestream due to activities of the user.
Based on my inquiry of the person or persons directly responsible for managing compliance with the pretreatment standard for 40 CFR __________ [specify applicable national pretreatment standard part(s)], I certify that, to the best of my knowledge and belief, there has been no increase in the level of ____________________ [list pollutant(s)] in the wastewaters due to the activities at the facility since filing of the last periodic report under Section 710.160.
7. 
All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report 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 Superintendent or other parties approved by EPA.
8. 
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, based on data that is representative of conditions occurring during the reporting period. For sampling required in support of baseline monitoring and ninety-day compliance reports required in Section 710.160, a minimum of four (4) grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Superintendent may authorize a lower minimum. For the reports required by Section 710.160(B), the industrial user is required to collect the number of grab samples necessary to assess and assure compliance by with applicable pretreatment standards and requirements.
C. 
Record Keeping. 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, any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements, and documentation associated with best management practices established under Section 710.160(B)(3). 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; 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.

The City shall inspect the facilities of any user to ascertain whether the purpose of this Chapter is being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the City or their representative ready access at all reasonable times to all parts of the premises for the purposes of inspection, sampling, records examination or in the performance of any of their duties. The City, approval authority and (where the NPDES State is the approval authority), the EPA shall have the right to set up on the user's property such devices as are necessary to conduct sampling inspection, compliance monitoring and/or metering operations. Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements with their security guards so that upon presentation of suitable identification, personnel from the City, approval authority and EPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities.
[R.O. 2014 §710.190; Ord. No. 414 §4.6, 9-25-1980; Ord. No. 574 §4.6, 5-10-1990; Ord. No. 1977, 1-14-2021]
A. 
Users shall provide necessary wastewater treatment as required to comply with this Chapter and shall achieve compliance with all Federal Categorical Pretreatment Standards within the time limitations as specified by the Federal pretreatment regulations. 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 acceptable to 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 effluent acceptable to the City under the provisions of this Chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the City prior to the user's initiation of the changes.
B. 
The City shall annually publish in the Marshfield Mail newspaper a list of the users which were not in compliance with any pretreatment requirements or standards at least once during the twelve (12) previous months. The notification shall also summarize any enforcement actions taken against the user(s) during the same twelve (12) months.
C.

D. 
The term significant non-compliance shall be applicable to all significant industrial users (or any other industrial user that violates Subsections (D)(3), (4) or (8) of this Section) and shall mean:
1. 
Chronic violations of wastewater discharge limits, defined here as those in which sixty-six percent (66%) or more of all the measurements taken for the same pollutant parameter taken during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits as defined in Section 710.040;
2. 
Technical Review Criteria (TRC) violations, defined here as those in which thirty-three percent (33%) or more of wastewater measurements taken for each pollutant parameter during a six-month period equals or exceeds the product of the numeric pretreatment standard or requirement including instantaneous limits, as defined by Section 710.040 multiplied by the applicable criteria (1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH);
3. 
Any other violation of a pretreatment standard or requirement as defined by Section 710.040 (daily maximum, long-term average, instantaneous limit, or narrative standard) that the Superintendent determines has caused, alone or in combination with other discharges, interference or pass through, including endangering the health of POTW personnel or the general public;
4. 
Any discharge of a pollutant that has caused imminent endangerment to the public or to the environment, or has resulted in the Superintendent's exercise of its emergency authority to halt or prevent such a discharge;
5. 
Failure to meet, within ninety (90) days of the scheduled date, a compliance schedule milestone contained in an individual wastewater discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance;
6. 
Failure to provide within forty-five (45) days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, periodic self-monitoring reports, and reports on compliance with compliance schedules;
7.

E. 
A CIU may obtain a net/gross adjustment to a categorical pretreatment standard in accordance with the following Subsections of this Section.
1. 
Categorical pretreatment standards may be adjusted to reflect the presence of pollutants in the industrial user's intake water in accordance with this Section. Any industrial user wishing to obtain credit for intake pollutants must make application to the City of Marshfield. Upon request of the industrial user, the applicable standard will be calculated on a "net" basis (i.e., adjusted to reflect credit for pollutants in the intake water) if the requirements of Subsection (E)(2) of this Subsection are met.
2. 
Criteria.
a. 
Either:
(1) 
The applicable categorical pretreatment standards contained in 40 CFR Subchapter N specifically provide that they shall be applied on a net basis; or
(2) 
The industrial user demonstrates that the control system it proposes or uses to meet applicable categorical pretreatment standards would, if properly installed and operated, meet the standards in the absence of pollutants in the intake waters.
b. 
Credit for generic pollutants such as biochemical oxygen demand (BOD), total suspended solids (TSS), and oil and grease should not be granted unless the industrial user demonstrates that the constituents of the generic measure in the user's effluent are substantially similar to the constituents of the generic measure in the intake water or unless appropriate additional limits are placed on process water pollutants either at the outfall or elsewhere.
c. 
Credit shall be granted only to the extent necessary to meet the applicable categorical pretreatment standard(s), up to a maximum value equal to the influent value. Additional monitoring may be necessary to determine eligibility for credits and compliance with standard(s) adjusted under this Section.
d. 
Credit shall be granted only if the user demonstrates that the intake water is drawn from the same body of water as that into which the POTW discharges. The City of Marshfield may waive this requirement if it finds that no environmental degradation will result.
F. 
The City of Marshfield may authorize an industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user. This authorization is subject to the following conditions:
1. 
The waiver may be authorized where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical standard and otherwise includes no process wastewater.
2. 
The monitoring waiver is valid only for the duration of the effective period of the individual wastewater discharge permit, but in no case longer than five (5) years. The user must submit a new request for the waiver before the waiver can be granted for each subsequent individual wastewater discharge permit. See Section 710.160(B)(6).
3. 
In making a demonstration that a pollutant is not present, the industrial user must provide data from at least one (1) sampling of the facility's process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes.
4. 
The request for a monitoring waiver must be signed in accordance with Section 710.020 and include the certification statement in 710.160(B).
5. 
Non-detectable sample results may be used only as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR Part 136 with the lowest minimum detection level for that pollutant was used in the analysis.
6. 
Any grant of the monitoring waiver by the Superintendent must be included as a condition in the user's permit. The reasons supporting the waiver and any information submitted by the user in its request for the waiver must be maintained by the Superintendent for three (3) years after expiration of the waiver.
7. 
Upon approval of the monitoring waiver and revision of the user's permit by the Superintendent, the industrial user must certify on each report with the statement in 710.160(B)(6), that there has been no increase in the pollutant in its wastestream due to activities of the industrial user.
8. 
In the event that a waived pollutant is found to be present or is expected to be present because of changes that occur in the user's operations, the user must immediately: Comply with the monitoring requirements of Section 710.160(B)(1), or other more frequent monitoring requirements imposed by the Superintendent, and notify the Superintendent.
9. 
This provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.

A. 
Information and data on a user obtained from reports, questionnaires, permit applications, permits and monitoring programs and from inspections shall be available to the public or other governmental agencies without restriction unless the user specifically requests and is able to 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 user.
B. 
When requested by the person furnishing a report, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public but shall be made available upon written request to governmental agencies for uses related to this Chapter, the National Pollutant Discharge Elimination System (NPDES) permit, State disposal system permit and/or the pretreatment programs; provided, however, that such portions of a report shall be available for use by the State or any State agency injudicial review or enforcement proceedings involving the person furnishing the report. Wastewater constituents and characteristics will not be recognized as confidential information.
C. 
Information accepted by the City as confidential, shall not be transmitted to any governmental agency or to the general public by the City until and unless a ten-day notification is given to the user.
