Document ID GM09-2001
Summary This amendment is to the Guidance for monitoring of point sources using low-level PCB method 1668 for TMDL development. It provides for the acceptance of PCB data generated using low level EPA Method 1668 revisions A, B, or C until EPA’s rulemaking process is complete and Method 1668 version C is promulgated. Additionally, the guidance memo is modified to account for variability associated with the generation of total PCB (tPCB) concentrations in final effluent samples.
