Part 1.7 Quarterly Ambient Monitoring Report

Dear Ms. Murphy and Mr. Haas:

I am pleased to submit a recently-finalized interpretive synthesis report providing results from MWRA’s baseline Outfall Monitoring Program and permit-required Ambient Monitoring program. Part I.7.c.iv of the permit requires:

"The results of all monitoring required by the ambient monitoring plan or the eutrophication model shall be reported to EPA, MADEP, OMSAP and NMFS, on a quarterly basis."

MWRA will provide raw monitoring data upon request.

If you require additional information or need clarification, please contact Michael Mickelson, Program Manager for Outfall Monitoring at (617) 788-4746.

Sincerely,

Michael J. Hornbrook
Chief Operating Officer
