Title Guidance for monitoring of point sources for TMDL development using low-level PCB method 1668
Document ID GM09-2001
Summary This guidance establishes procedures for implementing point source monitoring of polychlorinated biphenyls (PCBs) in support of Total Maximum Daily Loads (TMDL) development. This monitoring applies to the following categories of point sources discharging to PCB impaired waters: municipal (major and minor) and industrial wastewater facilities; and industrial storm water discharges, whether operating under an individual or general storm water permit. PCB monitoring entails sample collection and low-level analysis using EPA Method 1668 to determine individual PCB congener concentrations. This action replaces the current method that is unable to detect low-level PCBs against the Virginia water quality criterion for total PCBs.
