Rule PromulgationWhat's Next?
On February 13, 2013, EPA published in the Federal Register the revisions to the 1989 TCR. Look for it on the U.S. EPA Revised Total Coliform Rule Web page at http://water.epa.gov/lawsregs/rulesregs/sdwa/tcr/regulation_revisions.cfm. EPA anticipates greater public health protection under the Revised Total Coliform Rule (RTCR) requirements. The RTCR:
Public water systems must comply with the revised requirements by April, 2016. Until then, PWSs must comply with the 1989 TCR. The DEQ will amend the State rules in 2015 to adopt the RTCR.
What Recently Happened?
The previous rule revisions were promulgated on December 4, 2009. These rules adopted federal provisions of the National Primary Drinking Water Regulations promulgated under the federal Safe Drinking Water Act of 1974, as amended. The rules also updated and expanded Michigan 's long-standing public water supply (PWS) requirements. The amended rules affect waterworks system construction, planning and operation; required training for water system operators; and provisions to disperse grants for source water protection. The rule changes affect the rules Supplying Water to the Public, R 325.10101 to 325.12820.
Rule Changes: 3-page summary of the 2009 amendments.
