MWRA requesting revisions: • Effluent floatables sampling • Water column monitoring design • Sediment monitoring design Changes requested to number of sampling sites, sampling schedule, and parameters measured Goal: Study focused on potential region of influence of outfall, with reference sites for comparison.
NO changes proposed to: • Virtually all effluent monitoring remains the same • Contingency plan reporting • Modeling • Fish and shellfish monitoring • Red tide responsive monitoring • Continuous monitoring Cape Ann (GoMOOS A) and nearfield (Buoy 44013) • Indicator bacteria monitoring around the outfall • Harbor and river monitoring
Bacteria monitoring locations Fecal coliform and Enterococcus Monthly sampling Adverse condition sampling
