A. Reclaimed Water System — Renewal (FORM: RWS-R 02-21):
1. In Section IX, the Deeded owner for the parcels listed do not match the owners that are shown on
the Wake County iMAPS online GIS map. This section shall be updated with the correct owners,
and any Easement, Encroachment, and Lease Agreement applicable shall be provided to verify that
the Permittee is allowed to operate and maintain the reclaimed water facilities on property not
owned by the Permittee.
B. Attachment C — Flow Reduction:
1. It was indicated in this attachment that there was not an approved flow reduction in the existing
permit. However, Conditions I.1., VI.4., and VI.5. of the existing permit indicate a data -based
design flow rate of 240 gallons per day per home (GPD/home). In accordance with this attachment,
the flow reduction approval letter shall be provided, as well as the measured monthly average
amount of wastewater flow contributed per home for the 12 months prior to permit renewal.
C. Attachment I — Compliance Schedules:
1. See Item B.1. Condition I.1. of the previous permit stated that within 60 days of the permit effective
date, the Permittee shall re-evaluate the approved value using the methodology used to determine
in the approved flow rate of 240 GPD/home or lot and submit this information as required in
Condition VI.4. Condition VI.4. requests the actual monthly average amount of wastewater flow
contributed per unit for the 12 months prior to permit renewal and re-evaluate the approved value
if monthly averages are within 20% of the approved value. This information shall be provided for
review, and a re-evaluation of the approved 240 GPD/home shall be provided if required.
D. Existing Permit:
1. The Attachment B in the existing permit lists the Dedicated Land Application Sites (previously
Non -Conjunctive Land Application Sites) associated with the permit. This Attachment appears to
group common areas of Front 9 Fairways and Greens, Back 9 Fairways and Greens, Practice Areas
and Greens, and Driving Range Tees and Fairways. However, it is unclear whether these field areas
are irrigated as single zones with uniform applications based on the irrigation operations at this
facility. If there are separate zones within the fields as they are listed in Attachment B that irrigate
separately and at different rates, they shall be listed as separate fields for monitoring purposes of
the land application fields
If the subzones are irrigated separately within the fields as they are currently listed, they shall be
listed in an updated Section IX of the RWS-R form with the location and area of the subzones.
Additionally, an updated site map shall be provided which shows the approximate locations of the
subzones with their wetted areas.
