Subject: Non -Discharge Permit Inspection
Town of Cherryville - Permit No.: WQ0000430
Land Application of Residuals
Gaston County
Dear Mr. Wright:
Staff of the Mooresville Regional Office (MRO) conducted an inspection of the referenced permit on
December 20', 2022. The MRO would like to thank you and Mr. Christopher Heedick for your time with
the facility and records review. The residuals processing, storage and records appeared to meet
program requirements at the time of inspection.
The following items of interest are noted for reference and continued compliance:
• Per the December 21 s1, 2022, email and letter from Central Office (CO) permitting, you currently
cannot land apply under your permit because all associated fields were transferred to Synagro's
Class B permit #WQ0016247. The City of Cherryville WWTP was also added as a source to
permit #WQ0016247, so Synagro may haul your material to the same fields but all reporting will
now be required under their permit.
Based on your discussion during this site inspection, MRO staff was of the impression you
informed your Synagro contact you were not interested in sharing land and wanted to continue
your normal land application activity under your current program (permit #WQ0000430).
It appears there is miscommunication between you, your contractor, and your local landowners,
who signed waiver agreements with Synagro staff for the land transfer between permits. Should
you wish to continue land application under your WQ0000430 permit, you will need to determine
the best course of action to either transfer the fields back with new waiver agreements and / or
acquire new land, both of which will require a permit modification. You may contact MRO staff at
the information below or CO staff, Erickson. Saunders0D_ncdenr.gov for further assistance.
• The recently installed gauge at the residuals, storage lagoon appeared appropriately located as
you discussed. Per our conversation additional markings should be added to meet the required
tenths of a foot or one -inch increments as the current markings are in one -foot increments.
The inspection report should be self-explanatory; however, please contact Maria Schutte by phone (704-
235-2184) or email ( maria.schutte(ab_ncdenr.gov ) with questions.

Comment: This was an inspection of the WWTP Residuals processing,
storage and records only. MRO
staff attempted to coordinate the facility visit with their land application
event. Per Mr. Wright,
samples were collected in Oct. for planned LA in last quarter,
but Synagro never land applied
and were talking early next year.

Comment: Answers are based on results from the 2021 Annual Report - the most recent data onsite. Per
Mr. Wright, they were billed for sampling results collected by Synagro in October 2022, but a
LA event was never conducted and he did not receive a copy of the results. Their 2022
Annual Report will show no land application was conducted that year. MRO staff advised
resampling would be necessary for land application in Jan. 2023, or later and recommended
discussion with their contractor over the expressed concern for lab expenses incurred in 2022,
and not utilized.

Describe sampling:
Sample collection at the lagoon was discussed. Mr. Wright was uncertain how Synagro ensures a

Comment: Sampling should be adequate and represent if Cherryville and Synagro Sampling plan protocol
is followed. MRO staff will request to be notified of the sampling event for observation, but
recommends Cherryville plant staff routinely observe their contractor sampling events.

Comment: There was no transportation or land application activity conducted at the time of this
inspection. Odors and vectors were not detected at the residuals storage lagoon during this
site visit. A new gauge with one -foot increments was installed for lagoon free -board
measurements and discussed to add inch or tenth of inch increments to meet requirements -
See the Summary Section and Cover Letter, also highlighted are comments / concerns related
to recent land transfer that leaves this permit currently with no acreage for land application. It
appears there is miscommunication between City of Cherryville staff, Synagro staff and local
land -owners that has adversely impacted Cherryville staff's ability to manage and operate their
permit as they have historically.
