We invite your comments on draft modified permit ST0008121 for REC Solar Grade Silicon, a high purity polysilicon and silane plant in Moses Lake.
The facility discharges wastewater to the City of Moses Lake Sand Dunes Treatment Plant, a series of line evaporation ponds, lined storage pond and land application site. The permit modification reduces sampling for sodium, land treatment site monitoring, and groundwater monitoring.
