2 SCOPE OF WORK
2.1 BACKGROUND
The current Dyster system was installed in 2008 and is at the end of its lifespan. Other digester system
components are obsolete. The non-potable pumping system is beyond capacity. Ideally, we would like the gas
storage portion of this project to be completed during the summer to minimize the use of natural gas for process
heat.
The location of the facility as at: 1015 S. Gray Avenue, Pasco, WA 99301. See Figure 1 below for satellite view
of the facility.
