As a follow-up to our previous response:
In 2019 we noted that several modifications from the original designed had been implemented
at the facility and that plant performance was being impacted by several factors, including:
1. Modifications from the original design
2. Wastewater strength exceeding design parameters
3. Wastewater characteristic — specifically fibers
4. Nitrate recycling
5. Return activated sludge
6. Control issues
7. Electrical issues
8. Limitations on aeration
9. Misc. other issues
The VFD continued to trip out so the blowers would stop every other day. This has been
replaced. Also, the mixer in train A went down and had to be replaced.
