chlorine to prove they are not using it. If the permittee wishes to use chlorine, the permit must include a permit limit for chlorine as well as a monitoring requirement.] Include the following for municipalities required to submit these plans. To make this determination, refer to the IMD on Implementation of the Methylmercury Criterion at: . Mercury Minimization Plan By the end of the twenty fourth month [timeframe is at discretion writer but must not exceed 24 months] after permit issuance, the permittee must submit an MMP (Mercury Minimization Plan) for approval. At a minimum, the MMP must include the following: Identification and evaluation of current and potential mercury (both MeHg and total) sources Identification and evaluation of conditions (i.e., anaerobic conditions) that might contribute to the methylation of elemental mercury in the collection and treatment systems Identification of industrial, commercial and residential sources of mercury A monitoring plan to confirm current or potential sources of mercury (Monitoring Plan) Identification of potential methods for reducing or eliminating mercury. These may include but are not limited to: BMP requirements or limits for industrial and commercial sources of mercury to a collection system Material substitution Material recovery Spill control and collection Waste recycling Process modifications Laboratory housekeeping, use and disposal practices and Public education. Ongoing monitoring of effluent to enable evaluation of the effectiveness and implementation of the MMP. Before approving the plan, DEQ will put the plan out on public notice for 30 days. The permittee must begin implementation of the plan within one month of DEQ’s approval. If DEQ determines that the MMP is not effective at reducing sources of mercury from entering its collection system, or if a water column translation of the fish tissue criterion is developed, DEQ may reopen the permit to modify the permit conditions. These modifications may include but are not limited to the addition of a numeric effluent limit. SCHEDULE B: MINIMUM MONITORING AND REPORTING REQUIREMENTS

Pretreatment Monitoring The permittee must monitor both influent and effluent according to the table below and report the results annually. Note: the following table should be modified to include any pollutant for which a local limit has been established or a MAHL (Maximum Allowable Headworks Loading) has been calculated or that has been identified as a pollutant of concern.

The following language applies to municipal facilities, some minor municipal facilities and industrial facilities. Refer to RPA IMD for more detail. Tier 1 Monitoring: Effluent Toxics Characterization Monitoring The permittee must analyze effluent samples for the parameters listed in tables B3-B8? [modify tables as appropriate not all permittees are required to monitor all parameters] below. The permittee must collect samples at specify location such as at the end of the active chlorine contact channel on a quarterly basis in the first year following permit issuance. Samples must be 24 hour composites except as noted in Tables B2 and B3 for Total Cyanide, Free Cyanide and Volatile Organic Compounds. Additional monitoring may be required based on the results of this monitoring. This additional monitoring is referred to as Tier 2 monitoring, and is described in more detail in condition 6?: Ambient and Additional Effluent Characterization Monitoring. Sample results must be submitted to DEQ using DEQ’s Electronic Data Delivery (EDD) system. For more information, go to: .
Acute toxicity The permittee must monitor 4 times over the permit cycle with each sample collected during a different quarter (modify as needed for seasonal discharges). All four samples may be collected in the For acute toxicity: Grab or Composite, taken specify location, such as: after dechlorination and before the effluent flume. Location should be the same as monitoring for parameters that may contribute to toxicity.

The corresponding dilutions are as follows: ZID: XX Mixing zone: XX A template for providing WET test results is provided below. Chronic toxicity For chronic toxicity: 24-hr composite, specify location, such as: after dechlorination and before the effluent flume. Location should be the same as monitoring for parameters that may contribute to toxicity. The permittee must submit the results of WET using the template below, along with laboratory reports.
