No landfill activities <br />occur in this area. It is classified as <br />industrial because of the soil borrow <br />activities. ST-2 is a potential outfall. It <br />receives flow from this area and the non- <br />industrial area to the northwest to a low <br />spot/impound area which has not been <br />observed to discharge due to its impound <br />capacity. <br />Area B – Landfill Module 2A. As of 2019, <br />storm water runoff is discharged to the <br />expanded retention pond on the south side <br />of this module <br />Area D – Area of industrial activity that <br />includes landfill module 1 (capped and <br />inactive) and landfill module 2 (active), the <br />storage building, fuel tanks and fueling, and <br />equipment maintenance. Entire area has the <br />potential for soil erosion. It drains to the <br />northeast retention basin and the discharge <br />point for this area is SW-5. <br />Landfill Module 2 (active and lined) Area E – Northeast retention basin. Receives <br />storm water runoff from Area D and ultimately <br />discharges by overflowing/discharging at <br />Discharge Point SW5 to a seasonal creek. <br />Retention Basin Area F – Is being excavated for daily cover. It <br />has small retention basin and receives some <br />flow from Area D. In 2019, Stockpile C will be <br />created as a part of the Module 2B project. <br /> <br /> <br />A <br />Non-industrial <br />Non-industrial <br />Non-industrial <br />ST-5 <br />Non-industrial <br />Soil borrow area <br />Stockpile C <br />Landfill gas energy plant <br />Stockpile A <br />Landfill module 2 (active with <br />equipment fueling, maintenance, <br />waste segregation, and condensate <br />re-injection and dust control) <br />Landfill Module 2A <br /> <br />G <br />ST-2 <br />ST-4 Area H – This area is non-industrial and <br />includes the scale house / fee entry gate, the <br />care-taker’s home, and employee and visitor <br />parking. Water discharges from this area to <br />Discharge Point SW-6, but starting in Spring <br />2018, it became a non-industrial area, and will <br />no longer be sampled or monitored. <br />Area G – Is the Landfill Gas Energy Plant. <br />Industrial activities include the storage of oil, <br />urea, propylene glycol, and landfill <br />condensate. It receives run-on from the area <br />north of it and discharges to a small retention <br />basin located on the south site. The storm <br />water Discharge Point SW-4 is where water <br />discharges from the basin into a seasonal <br />creek. <br />IGP storm water discharge <br />sampling and monitoring location <br />ST-3 <br />ST-2 <br />Non-industrial <br />Non-industrial <br />Soil borrow area <br />Stockpile B <br />New Landfill Module 2B <br />Retention Basin <br /> <br /> <br /> <br /> <br />Map Created by <br />WGR Southwest Inc <br />Revised 15Jun20.
