Groundwater results for calendar year 2014 at the Area I background well and review boundary wells showed the following: • The background well (MW -4A) and all three review boundary wells had pH values below the range of 6.5 to 8.5 SU for both monitoring events (April and November 2014 ); • MW -4A had iron and manganese values above the standard for both events. • MW -5 had iron values above the standard during both events and a manganese value above the standard for the April event. Groundwater results for calendar year 2014 at the Area III background well and review boundary wells showed the following: • The background well (MW1A) and all review boundary wells had pH values below the range of 6.5 to 8.5 SU for both monitoring events (April and November). • MW1A had chromium, manganese, and iron values above the applicable standard for the November event. 0 MW3 had a chromium value above the standard for the November event; and iron and WQ0000020 —Annual Submittal February 17, 2015 manganese values above the standard for both events. • MW2 had manganese values above the standard for both events • MW3 had manganese values above the standard for both events; and'iron and chromium values above the standard for the November event • MW4 had iron and manganese values above the standard for both events • MW5 had manganese values above the standard for both events • MW6 had iron and manganese values above the standard for the April'event • MW7 had manganese values above the standard for,both events Groundwater results for calendar year 2014 at the Area IV background well and review boundary wells showed the following: • The background well (MW1A) and all review boundary wells had pH values below the lower range of 6.5 to 8.5 SU for all monitoring events. • MW1A had chromium, manganese, and iron values above the applicable standard for the November event.' • For all six review boundary wells, only one, MW5 had any values above the standard. MW5 had a manganese value above the standard for the November event. The form 'DMSDF' for the Asheville Steam Plant has been marked as 'compliant' during calendar year 2014 with all conditions of the permit as DEP does not believe that a contravention of the groundwater standards occurred at these fill sites. We include the ash distribution information on forms that the Department has provided. Additionally we are providing a summary of the TCLP results in the attached table.
