Dear Mr. Boss,

This letter is written on behalf of the Trillium Links & Village LLC to provide
information as to remedial action taken to the above referenced facility. RPB Systems,
Inc. is the contract operations firm, which operates this facility.

As outlined in your July 6, 2021 letter we exceeded a daily maximum BOD with
64.5 mg/L and 9.9 mg/L over the 7.5 mg/L permit limit for 2021. The number of daily
violations was increased trying to resample for better results. All resulting in a monthly
average violation as well with a 20.48 mg/L over the 5 mg/L limit. We had a violation for
Ammonia Nitrogen monthly average of 4.28 mg/L over the 3 mg/L monthly limit.

We have identified leaks in the membranes filter which most likely contributed to this
BOD exceedance. The owner has ordered replacement membranes that should arrive
near the end of August. We are not able to repair the leaks in the membranes without
replacement units.

We have also purchased microorganisms to enhance the biological MLSS to help the
damaged membranes perform better.

I trust you will call if you have any further questions or concerns.

Robert Barr
