Spur, Bear River National Wildlife RefugeBACKGROUND
The wastewater flows received by the 2.0 MGD Perry/Willard Regional Wastewater Treatment Plant (PW-WWTP) travel through two Parshall Flumes, one for Perry City and one for Willard City,
prior to combining and entering the Treatment Plant. The wastewater enters the treatment plant and passes through a Huber SSL Fine Step Screen to remove debris and various items from
the wastewater. After passing the Screening area, the wastewater flows into a Grit Removal System where sand, grit and fine particles are removed.  Once the wastewater flows through
the screen and grit removal, it is pumped to the top of the plant where the biological process begins.The biological process for the PW-WWTP is an STM Aerotor, or more generically, an
Integrated Fixed Film and Activated Sludge Bioreactor (IFAS). From the IFAS the wastewater flows into clarifiers, where the solid biomass settles and is removed, and the clean water
is sent to a Trojan UV Disinfection system and then discharged into a pipeline to the Willard Spur Tailrace thence to the Great Salt Lake Transitional Wetlands/Bear River Wildlife Refuge.
PW-WWTP can divert the water from the pipeline to be used for Type II Reuse on property adjacent to the treatment plant. The facility did not discharge to the Willard Spur for the entirety
of the last permit cycle. PUBLIC COMMENTSDuring the public comment period provided under Utah Administrative Code (UAC) R317-8-6.5, any interested person may submit written comments
