EPA has modified MWRA’s consecutive system monitoring agreement to require that fully supplied MWRA communities served by the Carroll Water Treatment Plant pilot certain aspects of the Lead and Copper Rule revisions (LCRR), prior to their official compliance date of October 2024. As EPA has not issued official guidance documents or templates yet, MWRA, MassDEP and EPA Region 1 staff collaborated on drafts of templates for the required 24-hour Tier 1 Public Notice and for the revised Public Education brochure.
These documents are only applicable to MWRA at this time, but provide examples of what the eventual EPA required materials may look like.
Public Notice Template
The LCR Revisions require that any community with a 90th percentile result over the lead Action Level in required LCR residential monitoring issue a Tier 1 Public Notice with 24 hours of being notified of the exceedance.
Public Education Template
As with the current LCR, the LCRR will require that any community with a 90th percentile result over the lead Action Level issue public education materials to all its customers and a number of specific additional groups within 60 days of the end of the monitoring period. This template would be customized by the community with local results and other local information, approved by MassDEP, and then printed and distributed.
