Re: Notice of Violation NOV-2019-LM-0012
NPDES Permit NC0088056 Blacksmith Run Henderson County

Dear Mr. Davidson,

This letter is written on behalf of Vista Developers at Blacksmith Run to provide
information as to remedial action taken to the above referenced facility per your February
19th, 2019 letter attached.

We have had daily maximum BOD violations for March, April, May, June, and now
November 2018. We do not know the reason for these spikes but coincide with very high
influent BODs we collected on 950mg/L-6130 mg/L. As you know package plants are
designed for only domestic waste loading of 200-250 mg/L influent BOD.

The site is rapidly being built out by the developer and have asked if they are aware of
any toxic waste being dumped into the system of which they do not.

We are still trying to determine the cause of these influent spikes.

We will show the continuous flow readings which we have on the edmr site and
discontinue the holiday drop down menu we thought we were to use previously as stated.

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

Robert Barr
