III. EXISTING FACILITIES: z AND RENEWAL APPLICATIONS
1. Are there appropriately certified Operators in Charge (ORCs) for the facility? Yes No N/A
ORC: Jeffrey Evans Certificate #:1003660 Backup ORC: Mark Jones Certificate #:26812
2. Are the design, maintenance and operation of the treatment facilities adequate for the type of waste and disposal
system? Yes or No
If no, please explain: The WWTP is currently under a SOC due to persistent violations primarily related to
Infiltration and Inflow (I&I) issues, and therefore the plant has not been able to adequately treat the amount of
flow coming in. An Authorization to Construct (AtC) is currently under review.
Description of existing facilities:
 Bar screen
 Aerated grit chamber
 Dual primary clarifiers
 Primary lift station
 Four (4) aeration basins with coarse air diffusion
 Two (2) secondary clarifiers with return sludge
 Chlorine contact basin
 Two (2) chlorinators
 Dechlorination equipment
 Instrumented flow measurement
 Standby power
 One (1) primary sludge gravity thickener
 One (1) secondary sludge gravity thickener
 One (1) aerated sludge holding tank
 Belt filter press
 Sludge stabilization equipment
Proposed flow: No Change.
Current permitted flow: 6.0 MGD

Explain anything observed during the site visit that needs to be addressed by the permit, or that may be important
for the permit writer to know (i.e., equipment condition, function, maintenance, a change in facility ownership,
etc.) Significant repairs are continually needed to maintain operations. The facility was unable to
accurately measure flow back when this inspection was conducted. Overall, most system components were
not adequately working at the time of the inspection, which was mostly due to continual I&I and the
WWTP cannot handle the increased flow, causing issues throughout the system. The permittee is currently
under SOC WQ S19-005 (hereafter SOC), and I&I will be assessed and repaired to decrease flow into the
system, and an AtC for upgrades to the WWTP is currently under review.
3. Are the site conditions (e.g., soils, topography, depth to water table, etc) maintained appropriately and adequately
assimilating the waste? Yes or No N/A
If no, please explain:
4. Has the site changed in any way that may affect the permit (e.g., drainage added, new wells inside the compliance
boundary, new development, etc.)? Yes or No
If yes, please explain:
5. Is the residuals management plan adequate? Yes or No
If no, please explain:
6. Are the existing application rates (e.g., hydraulic, nutrient) still acceptable? Yes or No N/A
If no, please explain:
7. Is the existing groundwater monitoring program adequate? Yes No N/A
If no, explain and recommend any changes to the groundwater monitoring program:
8. Are there any setback conflicts for existing treatment, storage and disposal sites? Yes or No
If yes, attach a map showing conflict areas.
9. Is the description of the facilities as written in the existing permit correct? Yes or No
If no, please explain: The anaerobic digester has been converted to an aerated sludge holding tank.
10. Were monitoring wells properly constructed and located? Yes No N/A
If no, please explain:

11. Are the monitoring well coordinates correct in BIMS? Yes No N/A
If no, please complete the following (expand table if necessary):
Monitoring Well Latitude Longitude
○ ′ ″ - ○ ′ ″
○ ′ ″ - ○ ′ ″
○ ′ ″ - ○ ′ ″
12. Has a review of all self-monitoring data been conducted (e.g., DMR, NDMR, NDAR, GW)? Yes or No
Please summarize any findings resulting from this review: See Fact Sheet 2021, Section 5. Compliance
Summary.
Provide input to help the permit writer evaluate any requests for reduced monitoring, if applicable.
13. Are there any permit changes needed in order to address ongoing BIMS violations? Yes or No
If yes, please explain: Permit writer has already addressed these issues. Permittee is currently under a SOC
and this is reflected in the new permit.
14. Check all that apply:
No compliance issues Current enforcement action(s) Currently under JOC
Notice(s) of violation Currently under SOC Currently under moratorium
Please explain and attach any documents that may help clarify answer/comments (i.e., NOV, NOD, etc.)

occurred throughout the permit cycle. The permittee is currently under a SOC with plans to address I&I
issues and upgrade the WWTP.

If no, please explain:
15. Are there any issues related to compliance/enforcement that should be resolved before issuing this permit?
Yes No N/A
If yes, please explain: Permittee is currently under a SOC.
