Contingency Plan |
MWRA developed this plan to ensure that discharge from the
outfall does not result in adverse impacts to the Bay. The
Plan identifies thresholds that can suggest that effluent
quality or conditions in the Bay may be changing. |
| Contingency Plan
Exceedance Reports |
"Caution" or
"Warning" level exceedances of Contingency Plan
thresholds for water quality monitoring in Massachusetts Bay.
Designed to detect potential effects of the outfall. |
| Discharge Monitoring |
Reports
on the quality of effluent being discharged into Massachusetts
Bay. |
| CSO Variance: |
MWRA
has been granted a variance from having to meet water quality
standards in the Charles River and Alewife Brook/Upper Mystic
River. MWRA is implementing a plan to reduce the impacts of
combined sewer overflows (more
about the CSO Control Plan). |
| Flow Limitation |
Demand
management and water conservation efforts designed to minimize
flows to the Deer Island Treatment Plant. |
| Groundwater Remediation |
MWRA
prohibits discharges into the MWRA system for groundwater
remediation activities. The NPDES permit requires an annual
review of this policy. |
Local Limits |
A
review of MWRA standards and limits for discharges from certain
business or industrial sewer users. |
Operations & Maintenance |
Status
reports on routine maintenance of the sewer system, the sewage
treatment plant, and the sludge pelletizing plant; and a report
on steps taken to reduce leakage into MWRA's pipes. Notifications
about operational incidents or upsets. |
