On October 10th (Hey, we are September 13 !) EPA announced the long-awaited proposed revisions to the Lead and Copper Rule (LCRR) which was promulgated nearly 30 years ago under the Safe Drinking Water Act. There are some meaningful and significant changes in its nearly 350 pages. A combination of regulation and public awareness regarding lead risks has been effective and, as the proposal points out, the median blood lead level among children in the US has decreased by 95% since 1976. However, even low levels of lead can pose risks to children’s developing brains and bodies and lead can also be harmful to adults.
Replacement activities would be tied to concentration thresholds differently. Though the Action Level (AL) would remain at 15 ppb, the proposal introduces a new Trigger Level of 10 ppb. The primary goal of the Trigger Level is to provide utilities with an opportunity to identify treatment issues before a monitoring violation occurs.
I have not read the 350 pages but seems to me that there are no meaningful nor significant changes.
