A. Some of the spray heads have been capped off in Zones RC-03, RC-06, and UP-02 due to problematic
issues during irrigation events. Please provide an updated site map that shows the heads that are no longer
being used in these zones (and any others that have impacts) along with updated acreages for each impacted
zone.
B. Irrigation Zone RC-04 is actually two separate zones, 04A and 04B. The Attachment B has been updated
to list Zone RC-04A with max annual loading of 22.21 inches/year & Zone RC-04B with a max annual
loading of 36.84 inches/year. However, the acreage for each of these zones is unknown. Please provide the
acreages and updated coordinates for Zones RC-04A and RC-0413.
C. Irrigation Zone RC-08A and RC-08B were combined into RC-08, please provide updated coordinates for
Zone RC-08.
D. It was noted in the review that there are seven independent irrigation zones present for the standard
wastewater irrigation system, while only one field "N" was listed in the previous permit Attachment B.
These irrigation zones are dosed independently, one zone at a time. Please provide the acreages and updated
coordinates for Zones UP-0I through UP-07.
