Enclosed with this letter is a copy of the draft permit for the above referenced facility. I encourage you to
review these documents very carefully to ensure thorough understanding of the information, conditions,
and requirements contained therein.
You should be aware that the following changes have been incorporated into your permit:
• Updated address of facility on Cover page (please verify).
• Ammonia limits of 6.0/22.2 mg/l (Summer/Winter) have been added. These limits protect against
ammonia toxicity in the stream.
• Monitoring frequencies for ammonia and temperature changed to weekly and daily, respectively.
(Consistent with T15A: NCAC 2B .0500s)
• Quarterly monitoring for total nitrogen and phosphorus has been added. This change is consistent
with an effort to gather data about nutrient loading in this portion of the watershed.
Please review the draft permit carefully and submit any comments to David Goodrich no later than thirty
(30) days following receipt at the following address:

Special Condition(s): N/A.
Compliance History
• 1996 and '97 Compliance Inspection Reports indicated plant was operating well; only one daily max
fecal coliform violation noted the end of `95.
• Flows typically 500-600 gpd.
• Effluent TSS and BODS values usually less than 5 mg/l.
'96.
• Ammonia normally <0.1 mg/l.
• TRC normally 1000-2000 µg/l.
• Effluent fecal coliform normally <2/100 ml.
• Effluent temperatures okay.
BODS levels averaged slightly higher in
Additional Comments
• Only ATC on file is from 12/4/89 for a 7,000 gpd package treatment plant. Is this actual treatment
capacity? 0.0075 MGD (permitted limit) appears to have originated from the WLA for proposed
facility; is 0.0075 MGD the actual capacity?
• Ammonia calculations indicate that limits of 6.0/22.2 mg/I (S/W) protect against toxicity. This
facility's levels are well below the allowable concentrations (see calculations), and new limits should

not pose a compliance problem. Facility does, however, have a choice between ammonia limits or
whole effluent toxicity (WET) testing (quarterly chronic at IWC, 13%). Region, please confirm
which facility prefers, if it has not had the opportunity to choose. Permit has been drafted with
ammonia limits.
The allowable concentration of chlorine is 127 µg/l (see calculations); facility is discharging levels
high above that value. Facility should be encouraged to employ good plant practices when
disinfecting with chlorine so that minimal levels are discharged.

NOTES FOR WILKES CO. AIRPORT
PERMIT RENEWAL (NCO075078)
Wastewater discharge from Wilkes Co. Airport (Wilkesboro, Wilkes County) to UT to
Rock Creek in the Yadkin Pee -Dee Basin.
15A NCAC 2B .0300 Index # 12-(43): Rock Cr classified as C in 4/6/55.
ATC Information:
• 12 / 4/ 89 ATC issued for 0.007 MGD plant. (Permitted at 0.0075, based on proposed
facility, according to 1988 WLA files)
Basinwide Plan Information:
• Water quality in the upper Yadkin River at Patterson and Wilkesboro has improved
over the last decade, but sedimentation continues to be an issue. (This discharge is
in the center portion of the Yadkin watershed.)
• Nearest ambient station (021121000) is downstream of the W. Kerr Scott Reservoir;
upstream of the discharge.
• If petitioned, at least portions of Mulberry Creek may qualify for reclassification as
ORW or HQW; Mulberry is upstream of Rock Creek on the Yadkin.
• Yadkin River near Ronda and Elkin is support threatened due to fecal coliform
levels.
Correspondence:
• 1996 Compliance Inspection Report noted daily max fecal violation recorded on
12 / 6 / 9 5, but otherwise plant operated well.
• 1997 Compliance Inspection Report indicated plant operated well.
DMR Review:
• Flows typically 0.0005-0.0006 MGD.
• TSS usually < 5 mg/ 1.
• 197 BOD5 levels usually < 5 mg/l; higher on average in `96.
• Fecal coliform <2 / 100 ml.
• TRC normally 1000-2000 µg/l.
• Temperatures normal.
• Ammonia usually <0.1 mg/l.
General Comments:
Is actual design capacity 0.0075 or 0.007 MGD? Files not clear; last ATC in 1989
said 7000 gpd. Diagram submitted with application does not match this ATC—only
a 5000-gallon aeration basin, instead of a 7000-gallon. Will draft as 0.0075 and ask
region.
Calculations indicated ammonia limits of 6.0/ 22.2 mg/ 1 (S / W) are necessary to
protect against toxicity. Ammonia limits can be instated immediately; plenty of
retention time to reduce levels (as shown by data) .
Expiration date to be assigned to this permit is September 30, 2003.
