Inspection Date: 07/21/2021 Inspection Type : Annual Report Review
Reason for Visit: Routine
Inspection Summary:
This is an Annual Report review for activities that occurred under this permit for 2020. A site visit was not conducted as a
part of this review.
Values for PAN and SAR are provided for each source for the required reporting quarters. However, the populated formulas fc
these calculations were not presented. Future reports need to include the populated formulas for PAN and SAR.
All of the source facilities appear to have achieved the requirement for pathogen reduction.
There were no elevated metals reported in the TCLPs for the various sources. The TCLP for Granite Falls were collected in
2016. No recent TCLP data is available for Grant Falls WWTP.
The C.O.C. for both the 3rd Creek 4th Creek WWTP residuals collected on 10/1/2020 did not indicate the method of
preservation used. The laboratory receiving sheet indicated the samples were received on wet ice. Also, the C.O.C. for
Killian Creek collected o 10/29/2020 was missing the preservation method. Again, the lab receiving sheet indicates the
samples were received on wet ice. Future C.O.C.s need to indicate the method of preservation used for the collected
samples.
In a recent permit modification, the Killian Creek WWTP was added as a source to this permit. Data included for this facility
complete the Lincoln County AR for permit WQ0016922. In the future, please keep the data for the facility with the facility to
avoid confusion.
Granite Falls WWTP presented slightly elevate Benzene for various VOC samples collected during 2020.
The source should be careful to avoid petroleum compounds from getting into the sludge being processed for LA.
A total of 18 permitted fields received residuals during 2020.
All the fields that required lime amendments have received lime.

Comment: There are several sources listed under this permit. All sources have demonstrated pathogen
reduction by fecal analysis. West Stanley performs PVAR by 30-day bench Test. VAR is
demonstrated by S.O.U.R. testing at 3rd Creek and 4th Creek facilities. Columbus and Granite
Falls employ Lime Stabilization/Time on Temperature.
