required by MWRA's discharge permit.
Local Limits
MWRA regulates discharges from certain business or
industrial sewer users and prescribes standards and limits for both
the quantity and quality of substances that may be discharged. The
permit requires MWRA to develop and enforce these limits to prevent
pollutants from being introduced into the system that could interfere
with the operation or performance of the works, or cause problems
with NPDES compliance or sludge disposal practices. This site contains
analyses of these limits and any proposed changes in the limits.
Many of our reports are in PDF format, which requires Adobe
Acrobat Reader®, a free program available from Adobe
Systems. To request a paper copy of any report, please contact
the MWRA Environmental Quality Department at 617-788-4601, or e-mail us at web.enquad@mwra.state.ma.us.
