## Abstract

This rule makes minor changes to clarify and correct EPA's Drinking Water regulations. This rule clarifies typographical errors, inadvertent omissions, editorial errors, and outdated language in the final Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR), the Surface Water Treatment Rule, and other rules. In addition to these clarifications, EPA is adding optional monitoring for disinfection profiling and an earlier compliance date for some requirements in the LT1ESWTR, and a detection limit for the Uranium Methods. Also, EPA is reinstating text that was inadvertently dropped from the Lead and Copper Rule which listed the facilities that must be sent public education brochures by a public water system that has exceeded the action level for lead or copper.
