V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
Please have the applicant respond to the followingitems.
ems:
1. The facilities address listed in Item II.4. of Form WWIS 06-16 (i.e., the application) appears incorrect. Pender
County identifies the parcel as having a street address of 9240 US Highway 421 and not 2844 Caratoke Hi.ghwgy.
Please alter or explain.
2. The coordinates provided in Item II. 5. of the application seem inaccurate. The coordinates provided indicate that
the facility is located on the southeast corner of the intersection of US Hwy 421 and Montague Rd. It is believed
that the facility_ is to be located at the northeast corner of the intersection of the above roads. Please alter or
explain.
3. Items IV. 6. and 7. of the application propose a flow of 260 gallons per day. The application indicates that a flow
reduction has been allowed in lieu of the flows recommended within 15A NCAC 2T .0114. Please provide a copy
of the flow reduction approval or provide additional data to support the non-conformance to the referenced rule.
4. Item V. 5. of the application states that automatically activated standby power will be provided, however, Item
IX. 5. of the application indicates that it will not be provided. Since no further information regarding alternative
power supply was provided in the plans or specifications, please explain how the system will meet the
requirements of 15A NCAC 2T .0505(1).
5. The pump tank is indicated as having only one pump in Item V. 11. e. of the application. Please revise the tank to
include two pumps or explain how the system will comply with this requirement as cited in 15A NCAC 2T
.0505(k).
6. Item VIL 1. of the application states that the minimum depth to the season high water table within the proposed
irrigation area is 2.72 (assumed feet, although no units provided). This measurement does not seem to agree with
the report provided by Applied Resource Management, P.C. (ARM), dated May 9, 2022. In their report, ARM
indicates that the water table may be within 12 inches of the surface and was found to have been within six inches
of the surface during their investigation. Please alter or explain the discrepancy.
7. The plans should be revised to reflect or explain the following_
a. The pump tank should include a screened vent and this information as well as depiction of the controls
alarms and proper siege should be depicted in at least one of the plan sheets,
b. The dimensions included in Plan Sheet M100 could not be discerned and may be in conflict with those
provided in the calculations. Please provide a more legible version of the plans and ensure that all dimensions
agree with those provided in the calculations,
c. Plan Sheet C 101 identifies the location of a Temporary Skimmer Basin north of the proposed building and
west of the proposed wastewater structures. As this structure may violate setback requirements stated within
15A NCAC 2T .0506, please provide additional information regarding this structure includinganticipated
nticipated
cease of operation and procedures to remove the structure from operation, and,
d. Plan Sheet C101 depicts a 25 feet setback distance for surface water diversions, however, the pond located
near the northwest corner of the parcel appears to be a perennial water body which would have a setback
distance of 100 feet from the irrigation site. For this reason, the ARM report recommended reconstruction of
the pond to provide for the proper setback distance. Please revise the plans and specifications to provide for
the appropriate setback distance or otherwise explain.
8. The specifications should be revised to include the following_
a. Data sheets for the proposed UV disinfection system, and,
b. Additional information on construction of drip irrigation mound area, specifying ing type of soil to be used as
backfill, methods used to place the soil (e.g., tilling or discing etc.), etc.
