The report was prepared to summarize monthly wet season monitoring required by Monitoring and Reporting Program R5-2007-0833. As previously discussed with the Discharger, staff is concerned with the formation of leachate from operations and the potential for leachate to affect Potter Creek. Based on the analytical results from the required monitoring and sampling during the 2007/2008 storm water sampling, it appears that leachate has formed, that certain constituents of concern (COCs) are above EPA benchmark values, and these COCs are discharging from the Scotts facility into Potter Creek. In its 2008 Annual Report, the Discharger reported elevated concentrations above EPA Benchmark values for specific conductance, total dissolved solids, total phosphorus, and total metals (copper, zinc, and iron). Areas of concern appear to be runoff from the compost area (sample location SP-5), runoff from the paved surface (sample location SP-1 and SP-2) area, runoff from the manure pile, and Potter Creek. Although the runoff from the facility in general is a concern for water quality, it appears from the analytical data the highest exceedances of COCl are being reported from runoff associated with the compost area. In accordance with the MRP, staff requests the Discharger continue to implement the monthly monitoring and sampling program through the 2008/2009 wet season and to report the analytical results as required. As recommended in its 2008 Annual Report, the Discharger is reviewing the facility's storm water management procedures and is evaluating current and potential BMPs to prevent the formation of leachate and/or to prevent leachate from reaching groundwater or surface water. Therefore, by 15 October 2009 the Discharger must submit a report summarizing the evaluation of existing BMPs and any completed modifications to BMPs required to reduce or eliminate elevated COCs.
