III. EXISTING FACILITIES: MODIFICATION AND RENEWAL APPLICATIONS
1. Are there appropriately certified Operators in Charge (ORCs) for the facility? ® Yes ❑ No ❑ N/A
Wastewater:
ORC: Greg Spillman Certificate #: 1004824 WW-4
Backup ORC: Additional Information Request.
Spray Irritation:
ORC: Greg Spillman Certificate #: 1008006 SI
Backup ORC: Additional Information Request.
Need to remove from BIMS:
All other Operators that are not listed above or provided upon receipt of information.
Description of existing facilities:
As described in the permit. However, it is proposed to remove the —6 MG Storage structure in which a
closeout plan is currently in development. Permittee has requested removal of the 57.53 ac golf course
reclaimed water irrigation area and all appurtenances.
Proposed flow:
Current permitted flow: 300,000 GPD
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.)
Permittee has requested permit modification to remove all reclaimed use portions of permit. Current high
rate infiltration basins can accept 100% of permitted effluent flow and are performing well. The Permittee
plans to close the 6 MG storage lagoon per Division guidelines and transfer ownership to the golf course
owner. The WiRO will oversee lagoon closure per the guidelines. The 1.5 MG 5-day upset pond will be
used to meet the effluent storage requirement per 2T .0705(z).

10. 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:
GW-59: Reported pH is consistently low at all wells indicating a natural trend in the groundwater in this area.
There were no other 2L/permit limit exceedances in any of the wells.
NDMR/NDAR: One exceedance of the permit daily maximum for fecal coliform in October 2019, resulting in an
NOV. Measured groundwater lowering discharge (PPI 003) meets permit/2L standards. There was no reported
conjunctive use (golf course irrigation) during this period.
Provide input to help the permit writer evaluate any requests for reduced monitoring, if applicable.
11. Are there any permit changes needed in order to address ongoing BIMS violations? ❑ Yes or ® No
If yes, please explain:
