Y-12 National Security Complex Biological Monitoring and Abatement Program Plan
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
This document provides the Biological Monitoring and Abatement Program (BMAP) Plan for East Fork Poplar Creek (EFPC), as required by the Y-12 National Security Complex (Y-12 Complex) National Pollutant Discharge Elimination System (NPDES) permit which became effective December 1, 2011. The BMAP was first developed in 1985 by staff in the Environmental Science Division at the Oak Ridge National Laboratory at the request of the Y-12 Complex. The multidisciplinary and quantitative biological monitoring approaches used for the BMAP were developed, from the beginning, in close consultation with Y-12 Complex Environmental Compliance staff, as well as the State of Tennessee and the Environmental Protection Agency. A draft BMAP Plan was submitted to the Tennessee Department of Environment and Conservation (TDEC) in May 2012 and was approved by TDEC with revision in December 2012. The TDEC’s Plan changes are incorporated in this final BMAP Plan issued in January 2013. The general approach to the 2013 BMAP Plan follows previous precedent, and addresses all BMAP-related NPDES permit requirements. The focus of the monitoring effort is on EFPC and comparable reference streams, including Brushy Fork and Hinds Creek. Two other stream systems near the Y-12 Complex, Bear Creek and McCoy Branch, are similarly monitored using BMAP and TDEC protocols as required in the permit; however, these streams are monitored by Comprehensive Environmental Response, Compensation, and Liability Act -funded programs and are only briefly summarized in this Plan. Three major tasks comprise the current program: fish bioaccumulation, benthic macroinvertebrate community, and fish community. A concomitant task, toxicity testing of storm drains, is also implemented at the Y-12 Complex and briefly described in the Plan. Each BMAP task differs slightly in the number of sites and frequency of sampling, depending on need as determined by previous monitoring. Sampling rationale and specific methods for each task are provided herein. A summary of program integration components, including data management, quality assurance, and reporting aspects, are also provided. The BMAP is an internationally recognized biological monitoring program that is a valuable case study for the U.S. Department of Energy (DOE) and the nation. First and foremost, the program evaluates Tennessee Water Quality Criteria (as required in the NPDES permit) by conducting studies to annually evaluate bioaccumulation of contaminants of concern, and the receiving streams’ biological integrity. The program has been successful in evaluating ecological effects and their causes, and has provided actionable information in the design and application of pollution abatement actions. Most importantly, the program design focuses on assessing spatial and temporal change, and has documented substantial ecological recovery in response to various facility actions. The program results have therefore become a key measure of how well the DOE facilities are doing relative to protecting the environment, and provide assurance to regulators and the public that stream conditions are improving. The DOE’s mission and environmental management in Oak Ridge will continue to evolve as the facilities modernize and various decontamination and decommissioning activities and pollution abatement actions are implemented. Many changes are expected at the Y-12 Complex in the next few years that have the potential to positively affect, or on a short-term basis negatively affect, the stream environment. The BMAP approach described here will continue to provide an important integrated measure of receiving stream conditions and ecological response to future facility actions.
