The Optimization State – Kentucky

These are some news and views submitted by the AWOP states.  Please use this for your enlightenment, enrichment and maybe even your entertainment!  AND think about what your state wants to share for the next Optimization State.

The Kentucky AWOP team bid farewell to Jim Hamon, a founding member of the Kentucky AWOP, when he retired on October 1, 2010.  Even with budget constraints, Russell Neal was hired to fill that vacancy on January 16, 2011.  Russell comes to the group with a BS in Biology with a minor in Chemistry and a MS in Aquaculture and Aquatic Science from Kentucky State University.  Russell began his environmental work at the Kentucky State University in performing aquaculture research.  Russell will be providing technical assistance to drinking water systems that are located in the Hazard & Frankfort Regional offices.

The first quarter of 2011 has been full of activity, with the Kentucky AWOP team working to update the AWOP.  Kentucky made the decision to split the AWOP into two categories, a Microbial AWOP and a Disinfectants and Disinfection Byproducts (D/DBP) AWOP.  For the Microbial AWOP, the updates have not affected the existing goals, but rather the awards criteria.  Kentucky presents Microbial Optimization Certificates annually.  To receive an Optimization Certificate for being optimized, in addition to meeting the Microbial AWOP goals, the system must have no turbidity violations for the calendar year.  Systems must also submit turbidity data monthly.

For the D/DBP AWOP, specific D/DBP goals were set for both the treatment plant and distribution system.  Plant tap goals include TTHM and HAA5 limits, treated TOC limits, TOC performance removal ratio limits, and CT requirements.  Distribution goals include both short and long term TTHM and HAA5 limits, flushing requirements, and disinfectant residual limits.  Kentucky will be presenting D/DBP Optimization Certificates annually.  To receive an Optimization Certificate for being optimized, in addition to meeting the D/DBP AWOP goals, the system must have no Disinfection Byproduct violations for the calendar year.  Systems must also submit Plant Tap TTHM and HAA5, Distribution TTHM and HAA5, and Plant TOC data quarterly.

These new rules were put in place to further encourage systems to protect public health and maintain compliance.  Now for both the Microbial and D/DBP AWOP, in order for systems to be considered for optimization they must formally commit to AWOP.  To do this they must submit a letter of commitment, formally adopt the goals, and post them at a prominent location at their plant. To be in the running for either the Microbial AWOP Champion Award or the D/DBP AWOP Champion Award, a three year longevity award, the system will not be considered if they have any SDWA violations for the three year period.

    So what are the DBP goals to recieve the award?

    CT System Specific Goals (to include pH, Cl2 residuals, operating levels, etc..;
    seasonal variations should also be addressed) to be set by facility as
    part of their commitment letter. Minimum of 1.0 Required.
