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
