Except as provided in Section 29-49(c), there shall be no detectable amounts of mercury discharged into the POTW. The local discharge limitation for mercury is established at the method detection limit (MDL) in accordance with the following:
Mercury sampling procedures, preservation and handling, and analytical protocol for compliance monitoring shall be in accordance with EPA Method 245.1. The MDL, developed in accordance with the procedure specified in 40 CFR Part 136 shall not exceed 0.2 ug/L for mercury, unless higher levels are appropriate due to matrix interference.
The evaluation of potential matrix interference(s) shall include, at a minimum, the following:
a. 
A demonstration that the laboratory conducting the analysis is capable of achieving the MDL of 0.2 ug/L in reagent water;
b. 
A demonstration that the MDL of 0.2 ug/L cannot be achieved in the effluent; and
c. 
A demonstration that an attempt has been made to resolve the matrix interference(s).
In cases where true matrix interference(s) can be demonstrated, a discharge-specific MDL will be developed in accordance with the procedure in 40 CFR Part 136. Discharge-specific MDLs will be incorporated into the wastewater discharge permit of the nondomestic user.
Mercury Reduction Plans
To ensure that the maximum allowable mercury loading to the POTW is not exceeded, the control authority may require any nondomestic user with a reasonable potential to discharge mercury to develop, submit for approval and implement a Mercury Reduction Plan (MRP). The MRP may be required by permit if the nondomestic user has not violated the local limit for mercury, but the control authority has determined that a reasonable potential for such a violation may exist. MRPs may be required in notices of violations, orders or other enforcement actions when the nondomestic user has violated the mercury local limit. At a minimum, an approvable MRP shall contain the following:
a) 
A written commitment by the nondomestic user to reduce all nondomestic discharges of mercury to levels below the MDL within a time frame approved by the control authority;
b) 
Within 60 days of notification by the control authority that a MRP is required, the nondomestic user shall supply an initial identification of all potential sources of mercury which could be discharged to the POTW;
c) 
Specific strategies for mercury reduction with reasonable time frames for implementation, capable of ensuring that mercury discharges will be below the specified MDL within a time frame approved by the control authority;
d) 
A program for sampling and analysis of the nondomestic discharge for mercury in accordance with [EPA Method] 245.1 methods;
e) 
A demonstration of specific, measurable and/or otherwise quantifiable mercury reductions consistent with the goal of reducing mercury discharges below the specified MDL. Where such reductions cannot be demonstrated through normal effluent monitoring (e.g., mercury discharges are already near MDL), the demonstration should incorporate the following:
1) 
Internal process monitoring, documenting the results of mercury reduction strategies at sampling locations within the facility (e.g., a program of regular monitoring of sink traps where mercury-containing reagents had previously been disposed, but have since been substituted by non-mercury-containing compounds);
2) 
Internal and/or effluent sampling utilizing clean and/or ultra-clean sampling and analytical methods as referenced by USEPA Federal Register. Note that the results of such monitoring will not be used for compliance purposes unless performed in accordance with EPA Method 245.1 and collected at the appropriate compliance measurement location.
3) 
Loading calculations wherein the nondomestic user calculates the total mass of mercury reduced from the sanitary sewer discharge through reagent substitutions, changes in disposal practices and/or other approved MRP strategies implemented.
f) 
A semiannual report on the status of the mercury reduction efforts. At a minimum, these reports shall:
1) 
Identify compliance or noncompliance with specific reduction commitments in the MRP;
2) 
Summarize the analytical, mass-based or other quantifiable demonstrations of mercury reductions performed to date;
3) 
Provide all applicable analytical data;
4) 
Provide an evaluation of the effectiveness of actions taken to date;
5) 
Provide updates to the initial list of mercury-containing compounds discharged to the sanitary sewer; and
6) 
Propose for approval new strategies and/or modifications to the current MRP to continue and improve mercury reduction efforts.
g) 
Any other conditions that the control authority deems necessary to ensure that mercury reduction efforts are effective in achieving the goals of this section.
Failure to submit an approvable MRP within 30 days of the required due date shall constitute significant noncompliance in accordance with this section, and will result in publication as a significant violator, in addition to other possible enforcement action.
An MRP may be evaluated for adequacy at any time by the control authority. If such an evaluation determines that the Mercury Reduction Plan is inadequate, or the nondomestic user has not complied with its approved MRP, the nondomestic user will be notified. Failure to comply with the MRP requirement constitutes noncompliance. The control authority will follow its Enforcement Response Plan (ERP) to ensure that corrective actions are taken.
A nondomestic user may request a release from MRP requirements if (i) all samples of the discharge for a period of one year are less than the specified MDL; (ii) the nondomestic user has complied with the minimum monitoring frequency of quarterly sampling events; and (iii) the control authority deems that MRP commitments have been fulfilled sufficiently to ensure continued compliance with the mercury limitation. The control authority shall notify the nondomestic user of any release from MRP requirements in writing.
If the MRP requirement is waived by the control authority, the nondomestic user remains subject to the local limitation for mercury in accordance with the requirements of this section.
Re-discovery of mercury in the nondomestic user discharge subjects said user to the submission of a new MRP, or escalation of enforcement in accordance with the ERP.
(18) 
Any wastewater containing more of the substances referenced in Table 2, unless permitted by special discharge allocation under Section 29-50.
In addition to the limits in Table 2, any discharge that, in the judgment of the control authority, would contribute a significant amount of these substances, regardless of mg/l concentration, shall be prohibited except by special discharge allocation.

The control authority reserves the right to use COD sampling and testing for BOD special discharge allocations (see Section 29-50) and surcharges (see Section 29-51). In the event that COD is used for this purpose, the conversion to BOD shall be based on a site-specific COD/BOD ratio. The ratio used for this purpose shall be calculated based on a short-term demonstration using a minimum of five samples. The demonstration shall be performed at least every 24 months to check for any changes in the site-specific COD/BOD ratio.
(c) 
Dental amalgam.
(1) 
In accordance with MCLA § 333.16631 of Act 368 and the provisions of the Michigan Administrative Code, this section applies to a dentist who uses dental amalgam and to a dentist who removes dental amalgam. This section does not apply to any of the following:
a.

[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008; Ord. No. 1570, 11-2-2011; amended 12-4-2019 by Ord. No. 1776]
A nondomestic user (user) may, at the time of application for a wastewater discharge permit, or by a special discharge allocation permit application, request that the uniform concentration limits for BOD or COD, TSS, phosphorus, and grease and oil (polar fraction) be increased above concentrations listed in Table 2 (Section 29-49) for that permit. Such special discharge allocation shall be expressed as total daily pounds of pollutant discharged. A user's special discharge allocation shall be determined using rules and regulations established by the control authority and in accordance with procedures approved by the EGLE. The rules and regulations of the control authority shall be available for inspection at 42 South River Avenue, Holland, Michigan 49423, and shall be posted on the website of the BPW.
The control authority reserves the right to reduce or deny special discharge allocations if total pollutant discharges near or reach the MAHLs set forth in Table 3. The control authority reserves the right to amend the MAHLs set forth in Table 3 at its discretion. The special discharge allocation must not result in the POTW (including the collection system) receiving pollutants in excess of its ability to convey or treat.
A user which requests a special discharge allocation through the permit application process must sign a written acknowledgment whereby the user consents to comply with all terms and conditions which may be imposed by the control authority. Such acknowledgement shall be in a form provided by the control authority, and must be executed by an authorized representative of the user and be received by the control authority before any special discharge allocation is effective. The user shall be charged for the special discharge allocation as determined by the adopted rate schedule. Notwithstanding the foregoing, payment of the plant capacity portion of the surcharge rate shall not confer any right to any particular amount of capacity in future periods. In addition, the control authority reserves the right to institute a review of any previously permitted special discharge allocation at any time, pursuant to which the control authority, in its discretion, upon notice and the opportunity for hearing, may reduce or eliminate a user's previously permitted or approved special discharge allocation (including, in particular, but not limited to, any allocation amount for which a user has previously paid the physical plant capacity component of the surcharge but not the operation and maintenance component of the surcharge).
Any discharge in excess of the amount permitted by the special discharge allocation is prohibited and is therefore a violation of Section 29-49 and the user's wastewater discharge permit. In addition, a user shall pay the full surcharge rate (the plant capacity component and the operation and maintenance component) for any amount discharged in excess of the amount permitted by a special discharge allocation.

Surcharges for grease and oil (polar fraction) will be applied only if a user has received a special discharge allocation for grease and oil (polar fraction). Any users discharging above 50 mg/l may be required to submit grease trap maintenance records.
Surcharge rates shall be established periodically by the control authority. To determine the amount of the surcharge for any particular user, the control authority shall collect samples at a predetermined frequency and apply the surcharge rate to the analytical results of such samples. In the alternative, with the prior approval of the control authority, the user may utilize an independent company to take such samples, at the user's expense, under conditions and standards determined to be acceptable by the control authority. The surcharge shall be calculated and billed at a frequency determined by the control authority. Any surcharge billing not paid when due shall be a violation of this chapter.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
(a) 
Industrial users shall provide necessary wastewater treatment as required to comply with the most stringent requirement of this chapter, or federal pretreatment standards as established by 40 CFR Chapter N, Subpart I, or state standards or wastewater discharge permit conditions, and shall achieve compliance with all National Categorical Pretreatment Standards within the time limitations as specified by the federal pretreatment regulations, and with any other pretreatment standards by applicable deadlines.
(b) 
Any facilities required to pretreat wastewater 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 control authority for review, and shall be approved by the control authority before construction of the facility. The review and approval of plans and operating procedures does not relieve the industrial user from complying with the provisions of this chapter and wastewater discharge permit conditions. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and approved by the control authority prior to the industrial user's initiation of the changes.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
No user shall 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 concentration limitations as established herein or any pretreatment standard or requirement.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
(a) 
Nondomestic users shall provide protection from accidental discharge of materials which may interfere with the POTW by developing spill prevention plans. Facilities necessary to implement these plans shall be provided and maintained at the owner's or user's expense. Spill prevention plans, including the facilities and the operating procedures shall be approved by the control authority before construction of the facility.
(b) 
Nondomestic users that store hazardous substances shall not contribute to the POTW after the effective date of this chapter unless a spill prevention plan has been approved by the control authority. Approval of such plans shall not relieve the user from complying with all other laws and regulations governing the use, storage, and transportation of hazardous substances.
(1) 
The control authority shall evaluate all new SIUs for the need for a slug control plan within a year of the industrial user being designated as a SIU. Each significant industrial user shall be evaluated at least once every two years, and other nondomestic users as necessary, to determine whether such user needs a plan to control slug discharges. If the control authority decides that a slug control plan is needed, the plan shall contain, at a minimum, the following elements:
a. 
Description of discharge practices, including nonroutine batch discharges;
b. 
Description of stored chemicals;
c. 
Procedures for immediately notifying the POTW of slug discharges, including any discharge that would violate a prohibition under Section 29-49, with procedures for follow-up written notification within five days;
d. 
If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of industrial 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.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
(a) 
Notification of discharge violation.
(1) 
In the case of any discharge in violation of this chapter or wastewater discharge permit conditions, and in the case of any discharge that could cause problems to the POTW, including any slug discharges, as defined by Section 29-3 of this chapter, the user shall immediately notify the control authority of the discharge by telephone. The notification shall include:
a. 
The date, time, location and duration of the discharge;
b. 
The type of waste including concentration and volume; and
c. 
Any corrective actions taken by the user.
(2) 
Within five days following such a discharge the user shall submit a written report describing the cause of the discharge and the measures that will be taken by the user to prevent similar future discharges.
(3) 
Such notification shall not relieve the user of any expense, loss, damage, or other liability resulting from the discharge, nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed under this chapter or other applicable state or federal law.
(b) 
Notification of changed discharge. The user shall notify the control authority prior to the introduction of new wastewater or pollutants or any significant change in sewer use or characteristic of the wastewater being introduced into the POTW from the user's processes. Formal written notification shall be submitted prior to such an introduction. Significant change in sewer use is defined as an increase in the concentrations of pollutants discharged of 20% over those reported on the wastewater discharge disclosure report, or the increase in discharge volume of 1,000 gallons/day or more than 10% over that reported on the baseline monitoring report/wastewater discharge disclosure report, whichever is less.
Any change which would violate categorical pretreatment standards or local limits is prohibited.
(c) 
Significant industrial users are required to notify the control authority immediately of any changes at its facility affecting the potential for a slug discharge.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
Each nondomestic user shall permanently post a notice in a prominent place advising all employees to call the POTW, at the number supplied on the wastewater discharge permit, in the event of a dangerous discharge for which notification is required. Employers shall advise all employees who may cause or be injured by such a discharge of the emergency notification procedure.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
(a) 
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. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the date analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses.
(b) 
These records shall remain available for a period of at least three years after their collection.
(c) 
This period shall be extended during any litigation concerning compliance with this chapter or wastewater discharge permit conditions.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
All analyses, including sampling results submitted in support of any application reports, evidence or required by any permit or order shall be performed in accordance with the procedures and methods outlined in Section 29-80.2.
The sample shall be representative of daily operations. Where the standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the control authority or the applicable standards to determine compliance with the standard.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
(a) 
Information and data (other than effluent data) about a user obtained from reports, questionnaires, permit applications, permits and monitoring programs and from inspections shall be available to the public unless the user specifically requests and is able to demonstrate to the satisfaction of the control authority in accordance with state and federal disclosure statutes that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets of the user. Any such request must be asserted at the time of submission of the information or data. When such a confidentiality claim is asserted, the information shall be treated as such until a determination is made by the control authority. Effluent data shall be available to the public without restriction.
(b) 
When the person furnishing a report satisfies the control authority that such person has made the demonstration required by Subsection (a), the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection except by the state or EPA for uses related to this chapter, the NPDES permit, or the pretreatment program. Confidential portions of a report shall be available for use by the state or EPA in judicial review or enforcement proceedings involving the person furnishing the report. Effluent data will not be recognized as confidential information.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
Representatives of the control authority, the state and EPA, upon showing proper identification shall have the right to enter and inspect the premises of any user who may be subject to the requirements of this chapter. Nondomestic users shall allow authorized representatives of the control authority, state and EPA access to all premises for the purpose of inspecting, sampling, examining records or seize for purposes of copying records in the performance of their duties. Authorized representatives of the control authority, state and EPA shall have the right to place on the user's property such devices as are necessary to conduct sampling and monitoring. Where a user has security or safety measures in force which would require clearance, training, or wearing of special protective gear, the user shall make necessary arrangements at its own expense, to enable authorized representatives of the control authority, state and EPA to enter and inspect the premises as guaranteed by this paragraph.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
Compliance by existing sources with categorical pretreatment standards shall be within three years of the date the standard is effective unless a shorter compliance time is specified in the appropriate subpart of 40 CFR Chapter I, Subchapter N. Direct dischargers with NPDES permits modified or reissued to provide a variance pursuant to Section 301(i)(2) of the Act shall be required to meet compliance dates set in any applicable categorical pretreatment standard. Existing sources which become significant industrial users subsequent to promulgation of an applicable pretreatment standard shall be considered existing significant industrial users except where such sources meet the definition of a new source as defined in 40 CFR 403.3(k). New sources shall install and have in operating condition and shall "start-up" all pollution control equipment required to meet applicable pretreatment standards before beginning to discharge. Within the shortest feasible time (not to exceed 90 days), new sources must meet all applicable pretreatment standards.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
When the limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the control authority may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual industrial users.
Equivalent limitations calculated in accordance with 40 CFR 403.6(c)(3) and (c)(4) shall be deemed pretreatment standards for the purposes of Section 307(d) of the Act and Title 40, Part 403 of the Code of Federal Regulations. Industrial users will be required to comply with the equivalent limitations in lieu of the promulgated categorical pretreatment standards from which the equivalent limitations were derived.
40 CFR 403.6(c)(6) and (c)(7) shall apply to those industrial users for whom equivalent mass or concentration limits are calculated.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
Categorical pretreatment standards may be adjusted to reflect the presence of pollutants in the industrial user's intake water in accordance with 40 CFR 403.15.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
The control authority may at its discretion and subject to the conditions of 40 CFR 403.7, grant removal credits to reflect removal by the POTW of pollutants specified in the categorical pretreatment standard(s).
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
The BPW is authorized to inspect any existing building service sewer and drain, lateral or collecting sewers that discharge wastewater directly or indirectly to the POTW. If it is found that such lateral or collecting sewers are used or maintained in such a way as to cause discharge of septic wastewater or groundwater or debris which exceeds the design criteria of said sewer or any other substance deemed objectionable, the BPW will give notice of the unsatisfactory condition to the person responsible for such discharge and shall direct that the condition be corrected.
In cases of noncompliance continuing after such directive, the BPW, in its discretion, may discontinue service to persons responsible for such discharge.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
No person shall discharge or cause to be discharged to a sanitary sewer, either directly or indirectly, any nondomestic waste that creates a stoppage, plugging, breakage, reduction in sewer capacity or any other damage or loss to any public sewer, the POTW or the control authority. The person causing such discharge shall indemnify the BPW or control authority for any additional sewer maintenance expenses, or any other resulting costs or expenses, including attorney fees, caused by such a discharge.
[Ord. No. 1323, 12-5-2001; Ord. No. 1516, 9-3-2008]
Every user of the POTW shall provide, when deemed necessary by the control authority, protection from accidental discharge into the sewage system of nondomestic wastes or liquid materials not meeting the requirements of Section 29-49 or other nondomestic wastes.
