Human Health Criteria Work Group Meeting Minutes
The meeting focused on the evaluation of toxicity values and bioaccumulation factors for water quality standards. Discussion included transitioning from flowcharts to a spreadsheet format for reviewing toxicity data, specifically analyzing Integrated Risk Information System values and EPA-recommended criteria. Participants deliberated on the application of California EPA cancer slope factors, the scientific basis for criteria, and concerns regarding potential weakening of standards for certain compounds like cyanide and PAHs. Additionally, the group reviewed the methodology behind EPA's BAF derivations, contrasting them with BCFs and assessing the applicability of Great Lakes-based data to local conditions, with plans to finalize a report for the DEP Cabinet Secretary.

Human Health Criteria Workgroup Workgroup Meeting
The workgroup meeting focused on establishing ground rules, reviewing the proposed workgroup plan, and discussing the methodologies used by the EPA for human health criteria, specifically regarding fish consumption rates, bioaccumulation factors, and the K.O.W. method. Participants discussed scientific variables, data gaps, and the ultimate goal of making consensus-based recommendations to the Secretary regarding water quality standards. The group also reviewed competing proposals from the Manufacturers Association and the Rivers Coalition and planned future discussions regarding relative source contribution and bioaccumulation factors.

West Virginia Department Of Environmental Protection Public Meeting Minutes
The meeting addressed updates to Water Quality Standards, specifically regarding human health criteria and the methodology for deriving Bioaccumulation Factors. A significant portion of the session focused on algae monitoring and control efforts. Key discussion topics included the criteria for determining recreational impairment due to algae growth, the role of phosphorus as a limiting factor, and the performance impact of wastewater treatment plant upgrades on water quality in the Greenbrier River and other state waterways.
