SUBJECT: REQUEST FOR NPDES PERMIT RENEWAL OF TOWN OF MANTEO WWTP
PERMIT No. NCO079057
Manteo WWTP
Dare County
Please take this letter as the official request for the renewal of the Town's Wastewater
Treatment Plant NPDES Permit. All applicable applicant information has been provided in this
packet including this cover letter, the completed application form (EPA FORM 2A, Part A -C) and
our sludge management plan for the facility. Also included are a map of Outfall 001 and process
flow diagram of the WWTP.
We have started our wet tests as required for renewal. The second species toxicity tests will be
finished by August. Tests are scheduled for May 2017 through August 2017. Results will be
provided as they are available.
No physical changes have been made at the plant since the issuance of our last permit.
I am requesting a reduction of monitoring to our NPDES permit from existing permit
frequencies for the parameters BODS, TSS, NH3-N and enterococci to a 2/week minimum
frequency. The Town of Manteo WWTP has met all of the criteria listed in guidance for
approval for each of the requested parameters. No civil penalties have been issued in the last
three years. No daily, weekly or monthly violations have occurred at the WWTP in the last three
years. The WWTP and its employees are not under investigation or have committed criminal
violations in the past five years. I have included sample results for the last three years for the
requested parameters following this cover letter.
Percentages of limit for all parameters are under the 50% criteria. There were two total BODS,
TSS and NH3-N results over the 200% threshold for the last three years, under the limit -of 15.
1
There were two total Enterococci results over the 200% threshold for the last three years,
under the limit of 20. A breakdown of averages and percentages are below:
Three year arithmetic means: Parameter: Result:
BODS (April — October) .499 mg/L
BODS (November - March) .637 mg/L
TSS 6.0 mg/L
NH3-N (April — October) .001 mg/L
NH3-N (November - March) .091 mg/L
Three year geometric mean: Parameter: Result:
Enterococci 2.6 / 100 mL
Percent of limit: Parameter: Result:
BODS (April — October) 2.4%
BODS (November- March) 6.4%
TSS 1.8%
NH3-N (April — October) <1%
NH3-N (November - March) 3.6%
Enterococci 7.4%
I am also requesting a reduction of monitoring for our instream sampling for Outfall 001. We
currently sample 5 locations within Shallowbag bay as required by our permit once a week
during the year and three times per week June, July, August and September. In order to sample,
we must use a boat to get to each of the sample sites. At times during the summer, due to
storms or maintenance requirements to the boat, we have found it difficult to meet that
requirement. The summer months have become cumbersome on scheduling and staff as well
as the fuel cost for maintaining that many days a week. Our results have all come back within
normal ranges. Please consider reducing the summer requirement to once a week as is required
for the remainder of the year.
Sincerely,
Josh O'Brien

Application Information packet. The following items explain which parts of Form 2A you must complete.
BASIC APPLICATION INFORMATION:
A. Basic Application Information for all Applicants. All applicants must complete questions A.1 through A8. A treatment works
that discharges effluent to surface waters of the United States must also answer questions A.9 through A.12.
B. Additional Application Information for Applicants with a Design Flow >_ 0.1 mgd. All treatment works that have design flows
greater than or equal to 0.1 million gallons per day must complete questions B.1 through B.6.
C. Certification. All applicants must complete Part C (Certification).

b. The major pipes or other structures through which wastewater enters the treatment works and the pipes or other structures through which
treated wastewater is discharged from the treatment plant. Include outfalls from bypass piping, if applicable.
c. Each well where wastewater from the treatment plant is injected underground.

B.6. EFFLUENT TESTING DATA (GREATER THAN 0.1 MGD ONLY).
Applicants that discharge to waters of the US must provide effluent testing data for the following parameters. Provide the indicated
effluent testing required by the permitting authority for each outfall throu4h which effluent is discharpeed. fro not include information
on combine sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data roust comply with QAIQC requirements of 40 CFR Part 136 and other appropriate
QA/QC requirements for standard methods for analytes not addressed by 40 CFR Part 136. At a minimum effluent testing data must be
based on at least three pollutant scans and must be no more than four and on -half years old.

SUBJECT: DESCRIPTION OF SLUDGE MANAGEMENT PLAN
PERMIT No. NCO079057
Manteo WWTP
Dare County
Our sludge is wasted from our Secondary Clarifiers based on determination of MLSS, SVI, temp and other operational
factors. We closely monitor all lab results as well as fixed probes within our process units that communicate with our
SCADA system to make these decisions. The WAS is moved from our Clarifiers manually to anaerobic digester where it
is aerated for the appropriate amount of time based on the season for proper digestion of solids. When there is no
available volume left in the Digester, we turn the aerator off to allow the sludge to settle and are able to return a clear
supernatant back to the Headworks of the Treatment Plant. Once done with decanting, the aerator is returned to
working order. At the point that the sludge blanket in the Digester is too high that it effects the quality of supernatant,
we then move the thickened blanket to our Sludge Holding Lagoon for storage and further aeration and mixing.
We operate the Sludge Holding Lagoon in the same manner as the Digester for further digestion and thickening of solids.
When the Sludge Holding Lagoon has reached the appropriate percentage of solids, we stabilize the sludge by raising the
pH to above 12 standard units for 24 hours. Once the stabilization has been achieved, the sludge is hauled by truck and
land applied. The hauling is conducted by a contracted company as well as the land application of sludge.
Sincerely,
Josh O'Brien
