Foothill Landfill <br />Storm Water Pollution Prevention Plan <br /> <br /> <br /> <br />Page 60 <br />The following is a summary of the 2015-2016 storm water sampling that triggered the ERA <br />Level 1 status for the Foothill Landfill: <br />Table 12.2.1 – ERA Level 1 Episodes <br />Storm Water Year <br />Parameter <br />Triggering the Level <br />1 ERA <br />Average Analytical <br />Results NAL Drainage Areas Affected <br />2015-2016 Iron <br />TSS <br />34.7 mg/L <br />415 mg/L <br />1.0 mg/L <br />100 mg/L ST-3 <br /> <br />The Level 1 Report for iron was submitted onto SMARTS on December 28, 2016. A copy <br />of the Level 1 Report 3 and documentation is included in Appendix J. <br />12.2.2 Level 1 Return to Baseline Status <br />A facility with parameters at Level 1 status will return to Baseline status for that Level 1 <br />parameter if: <br />x A Level 1 ERA report had been completed with all identified additional BMPs having <br />been implemented. <br />x Sampling analytical results of the Level 1 parameters from four (4) consecutive QSEs <br />that were sampled subsequent to the Level 1 ERA report BMP implementation indicate <br />no additional NAL exceedances. <br />12.3 Level 2 Status <br />If a facility reaches Level 1 status for any parameter, the status will change to Level 2 if <br />sampling results indicate an NAL exceedance (General Permit, Table 2) for that same <br />parameter at any of the facility’s discharge points. Level 2 status will commence on July 1 <br />following the reporting year during which the NAL exceedance(s) occurred. <br />On July 1, 2017, Foothill Landfill entered a Level 2 ERA for iron. <br />Table 12.3 – ERA Level 2 Episodes <br />Storm Water Year <br />Parameter <br />Triggering the Level <br />1 ERA <br />Average Analytical <br />Results NAL Drainage Areas Affected <br />2016-2017 Iron 1.439 mg/l 1.0 mg/l ST-1, ST-6, and ST-7 <br />Note that ST-1, ST-6, and ST-7 were subsequently all eliminated from the monitoring <br />program because they were determined to be non-industrial discharge points. Please refer <br />to the Level 2 ERA Action Plan in Appendix J for more information. <br /> <br />12.3.1 Level 2 ERA Action Plan <br />If Level 2 status is reached, a facility must certify and submit, via SMARTS, a Level 2 ERA <br />Action Plan prepared by a facility designated QISP that addresses each new Level 2 NAL <br /> <br />3 See SWPPP Section 12.3.2 - Level 2 ERA Technical Report for ultimate findings of iron sources
