In response to NOV-2021-LV-0381 and NOV-2021-LV-0382 Monitoring Well constituents were
above limits on TDS, Chloride and Ammonia. With constant monitoring and tracking noticing during the
Winter months / slow season the constituents are increasing but as water levels increase the
concentrations have decreased. With the assistance of Jay Baker from Environmental Chemists we are
working together to find the cause of the seasonal increase with effluent quality within limits before
installing new Monitoring Wells. If we are unable to correct the issue we will be moving to the installation
of the new wells. Each month we are monitoring the well depths and are noticing as the water levels
increase the concentrations decrease. We have made attempts to schedule with Enviro Chem's sampler
to make note and report findings at the time of sampling to give a more detailed account of the conditions
and any other things that could contribute to this issue of compliance to relay to all parties to make the
best possible decision in correcting the non -compliant constituent samples.
In response to NOV-2021-LV-0379, effluent BOD was above limit due to solid levels in the plant
building in the Reactor Dosing tank in conjunction with algae growth. This caused the growth on the tank
walls to flake off in sheets and get transferred throughout the plant while Phase 1 was being retrofitted
with air headers to mix and decant clear water. Since the cleaning of the plant levels have returned to
normal with some fluctuation with the increased flows. Seasonal adjustments are being made to
compensate for these changes and have requested process and programming checks and adjustments
from F. R. Mahony who has agreed to completely go through the programming and electrical systems to
make any necessary changes.
