Summary

Notice is hereby given that the Navajo Nation revised its approved State primacy program under the federal Safe Drinking Water Act (SDWA) by adopting regulations that effectuate the federal Public Notification Rule (PNR). The Environmental Protection Agency (EPA) has determined that Navajo Nation's revision request meets the applicable SDWA program revision requirements and the regulations adopted by Navajo Nation are no less stringent than the corresponding federal regulations. Therefore, EPA approves this revision to Navajo Nation's approved State primacy program. However, this determination on Navajo Nation's request for approval of a program revision shall take effect in accordance with the procedures described below in the SUPPLEMENTARY INFORMATION section of this document after the opportunity to request a public hearing.

The agency’s own summary, as published.
