Annual Progress Report 2002
The Massachusetts Water
Resources Authority ("MWRA") files this CSO Annual Report for
2002 in accordance with the Federal District Court Order in the Boston
Harbor Case. Annual and quarterly CSO reports describe the progress of
work to complete MWRAs long-term CSO control plan relative to milestones
on the court-ordered schedule.
MWRAs long-term CSO control plan was recommended in the Final CSO
Facilities Plan and Environmental Impact Report (the "Facilities
Plan/EIR"), which MWRA filed with federal and state regulatory agencies
in August 1997. Together with certain plan modifications addressed in
subsequent Notices of Project Change and Supplemental EIRs, it recommends
25 wastewater system improvement projects (see Figure 1) to bring CSO
discharges at 84 outfalls in the metropolitan Boston area into compliance
with the federal Clean Water Act and state Water Quality Standards.
The Facilities Plan/EIR proposed elimination of CSO discharges to sensitive
use areas (i.e. beaches and shellfishing areas), significant reduction
and/or treatment of discharges to less sensitive waters, and means to
control floatable materials where CSO discharges will remain. Figure 2
summarizes the scope, schedule and benefits of the plan. The Facilities
Plan/EIR received state and federal regulatory approvals in late 1997
and early 1998, respectively, allowing MWRA to move the projects into
design and construction.
Design and construction milestones for all of the projects are included
in Schedule Six of the Federal Court Order in the Boston Harbor Case.
Schedule Six calls for the CSO plan to be fully implemented by November
2008, although MWRA has reported to the Court that completion of certain
projects, especially projects now undergoing reassessment due to implementation
obstacles, will take longer. MWRA expects to request changes to Schedule
Six upon completing each reassessment and reaching agreement with the
Court parties. Those projects and the circumstances necessitating more
time are reviewed in this report.
This annual report for 2002 reviews planning, design and construction
progress and accomplishments in 2002 and in the quarterly period December
17, 2002, to March 14, 2003. Like previous annual reports, it discusses
issues that have affected or may affect MWRAs ability to complete
the CSO projects on schedule and describes efforts to address problems
and move CSO control forward. In addition, this report looks back on ten
years of progress in CSO control in the Boston area since work to develop
the current plan began in 1992.
