Selenium fish tissue sampling is required for exceedances of many NPDES/KPDES permit limitations. The results must be submitted on the next months DMR so depending on the sampling dates this typically reduces the available sampling time to a short period after the exceedance is determined to when the sample can be collected.
Many Kentucky KPDES Permits now contain a Selenium Fish Tissue sampling trigger for collection of fish and application of EPA Method 200.8. This method identifies the amount of Selenium accumulated in the tissue of certain fish species. This methodology is outlined in the Methods for the Collection of Selenium Residue in Fish Tissue Used to Determine KPDES Permit Compliance SOP manual published by the Commonwealth of Kentucky Energy and Environment Cabinet, Department for Environmental Protection, Division of Water (KDOW, 2014).
