Slide 15: NPDES Compliance Update
NPDES Compliance Update 15 Positive results in 2010/2011 Just one exceedance at Outfall 008 (lead) Three exceedances at Outfall 009 (lead, dioxin [twice]) 100% compliance is challenging due to background sources and/or natural variability.
Slide 16: NPDES Exceedances: Total Lead
NPDES Exceedances Total Lead 50% 45% 11/25 Percent of samples above current Permit limit 40% 35% 30% 13/45 25% 20% 15% 1/6 10% 5% 1/13 0% Prior to 2010-2011 2010-2011 Prior to 2010-2011 2010-2011 Outfall 008 Outfall 009
Slide 17: NPDES Exceedances: Dioxin
NPDES Exceedances Dioxin (TCDD TEQ [no DNQ])* 50% *Based on current NPDES reporting 45% procedures for dioxins Percent of samples above current Permit limit 40% 35% 30% 15/45 25% 20% 15% 2/13 0% (0 of 6) samples 10% exceeded the dioxin 5% limit at Outfall 008 1/25 during 2010-2011 0% Prior to 2010-2
