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.

Notes: Chemical Abstract Service. All metals must be analyzed for total concentration unless otherwise specified. 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: .
