Kentucky Division of Water Finalizes Wastewater Laboratory Certification Program Regulations


On June 14, 2013, the Kentucky Division of Water (KDOW) filed the Statement of Consideration and amended Wastewater Laboratory Certification Program regulations with the Legislative Research Commission.  The regulation establishes wastewater laboratory certification and analytical requirements for monitoring data collected and submitted pursuant to KPDES permit requirements.  After January 1, 2015, all monitoring data submitted for KPDES permit compliance purposes must be analyzed by a certified wastewater laboratory, in accordance with analytical methods in 40 CFR Part 136 (or as established in the applicable KPDES permit) and the Wastewater Laboratory Certification Manual, which is incorporated by reference in the regulation.  Note that the wastewater certification regulation does not apply to municipal pretreatment programs.  Also, a certification is not necessary for a person that collects wastewater samples for KPDES permit purposes but does not conduct any field analysis or other laboratory analysis.

For KPDES permittees that conduct “field monitoring” only, the permittee will be required to be certified as a “field-only wastewater laboratory” by January 1, 2016.  A “field-only wastewater laboratory” is defined as a wastewater laboratory that performs a measurement for only the parameters identified as field analysis, regardless of whether the analysis is conducted at the monitoring site or in an on-site room used as a laboratory, or in an off-site laboratory operated by the permittee.  Field analysis includes dissolved oxygen, residual chlorine, pH, temperature, conductivity, and turbidity. To further reduce the regulatory burden on KPDES permittees that conduct field analysis and utilize a commercial lab for other required chemical analyses, KDOW has agreed to prepare templates with standard quality assurance plans (QAP) and standard operating procedures (SOPs) that are applicable for field analysis measurements that can be used to address all applicable requirements for QAPs and SOPs under the certification requirements.  KDOW will provide a public notice and opportunity for comment on the proposed templates before they are finalized.  Further, permittees that only conduct field analysis will not be subject to the annual administrative and certification fees.

The initial certification period for a general wastewater laboratory is January 1, 2014 through December 31, 2015.  The initial certification period for field-only wastewater laboratories is January 1, 2015 through December 31, 2016.  Subsequent certifications will also be for a two year period.  The requirements for obtaining and maintaining a wastewater lab certification are specified in the regulation and the Wastewater Laboratory Certification Manual, which is incorporated by reference.
