3 mg / L of TOC removal for 10 mg / L coagulant dose. At this point of change, the alternative removal percentage for TOC can be set. Exceptions There are no exceptions to the rule, but there are alternative compliance criteria. If the alternative compliance criteria are met, the system is deemed to have met the TOC removal requirements. 0 mg / L. 0 mg / L. 0 mg / L, the source water alkalinity is greater than 60 mg / L (as CaCO3), and the system’s DBP levels for TTHM and HAA5 are less than 40 ␮g / L and 30 ␮g / L, respectively.

The rule will stress a multibarrier approach, including best management practices and source water monitoring and contamination control. Potentially affected are all public systems using a groundwater source. This rule combines the LT1ESWT and FB rules to strengthen microbial controls for systems serving fewer than 10,000 people and prevent significant increase in microbial risk where small systems take steps to implement the Stage 1 Disinfectants and Disinfection By-products Rule. The LT1ESWTR will track the IESWTR for improved turbidity control, including individual filter monitoring and reporting.
