road/rail right-of-ways)
e. All facility -related structures and fences within the treatment, storage, and disposal areas
f. All habitable residences and places of assembly within 500 feet of all treatment, storage, and
disposal sites
g. Topographic contour intervals not exceeding 10 feet or 25 percent of total site relief
h. Soil mapping units on all disposal sites
i. Location of all wells, streams (ephemeral, intermittent, and perennial), springs, lakes, ponds,
ditches, and other surface drainage features within 500 feet of all waste treatment, storage, and
disposal site(s)
j. Location and identification of each monitoring well (identify any background/upgradient wells)
k. Latitude and longitude coordinates of all monitoring wells (decimal degrees to 6 digits)
1. Location and identification of major components of the waste disposal system
in. Identification of all storage or treatment earthen structures that are part of the permit
n. The wetted perimeter of all irrigation/infiltration fields with field names (named according to the
approved permit)
o. The delineation of compliance and review boundaries
p. 100-year floodplain (if applicable)
The site map submitted does not show the full permitted system, including, but not limited to the
location of the treatment plant, location of the components of the 500,000 gallon stormwater
collection and disposal facility, and the labeling of the rotary distributor infiltration beds. It also
appears that the property lines are outdated on this map. Please submit a map that fits the above
criteria. [15A NCAC 02T .0105(d)]
Section IV. 1. of FORM: NDSR 01-20 requires a listing of all monitoring wells at the facility, along
with their coordinates, gradient to the disposal field, and location in relation to the compliance and
review boundaries for the disposal fields. Please fill out table IV. 1. for the active monitoring wells
on site.

B. Existing Permit:
1. The facility description for the previous permit includes the following excerpt for a stormwater
collection system:
"the continued operation of a 500,000 gallon stormwater collection and disposal facility consisting
of a 354 GPM wet well pump station with duplex pumps, thirteen full circle impact sprinklers,
approximately 1,260 linear feet of 6-inch subsurface gravity drain pipe, 1,450 linear feet of 8-inch
force main and all related valves, piping and appurtenances;
The regional office indicates that this was put in place for when large storm events would cause a
surge of stormwater that would mix with raw sewage at the original wastewater facility. However,
it is unclear whether the current operations of this stormwater collection system reflect this original
intent. Please provide a narrative about the current operations of this stormwater system, including
any recent maintenance related to the system. This narrative should discuss the relationship of the
stormwater system and the other permitted wastewater treatment and high -rate infiltration disposal
facilities associated with the permit, and whether there is any interactions between these stormwater
and wastewater facilities.
