Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The review period for this inspection was October 2017 through August 2019. One Notice of Deficiency
was issued for BOD violations and one Notice of Violation was issued for a Toxicity limit violation.
The July 2019 DMR was reviewed and the following items need to be corrected:
7-10-2019 DMR had Copper reported as 0.003 ug/I with the lab result as 0.003 mg/I. Total Flow was
reported as 0.003 on 7-10-19 and needs to be deleted. Total Flow for the month was reported on
7-31-19.
The facility could not provide documentation that the Annual Report was completed last year. The
facility was reminded that an Annual Performance Report shall be provided no later than sixty days
after the end of the calendar or fiscal year, depending upon which annual period is used for evaluation.
