Dear Mr. Best:

Subject: Draft NPDES Permit NC0075680
Rosewood MHP WWTP
Grade II Biological WPCS
Buncombe County
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review
this draft carefully to ensure thorough understanding of the requirements and conditions it contains. We
understand that your treatment system is currently being upgraded in accordance with an Authorization to
Construct (ATC) issued in August 2019. There are a few changes in the draft from the existing permit
and some considerations for updates pending completion of the treatment system upgrade. These changes
and issues are discussed below.
Regulatory Citations — Language has been added where necessary in the permit to provide
regulatory citations for permit requirements.
Electronic Reporting — Permit language has been added to be consistent with the finalization of
federal requirements for electronic reporting.
Ammonia Nitrogen (NH3-N) Monitoring — In the current permit you monitor 2/Month for NH3-N
and have summer and winter effluent limits. Recent review by Division staff has noted that 15A
NCAC 2B .0404(c) requires that winter waste load allocations for oxygen consuming waste be no
less stringent than 2 times the summer waste load limit. To meet this rule requirement your
winter limits for NH3-N are being adjusted in the draft permit. This will result in a reduction of
the winter monthly average limits in your permit.
The draft permit includes proposed changes to the winter monthly average NH3-N limits as
indicated below.

Current Limits
Proposed Limits
0.02 MGD
20mg/L
15.6mg/L

A review of the monitoring data over the last permit cycle indicates that there were no
instances where monthly averages would have exceeded the proposed limit limits of
15.6mg/L and 11.0 mg/L. The highest monthly average value in these records is 8.1 mg/L.
Based on the DMR data review from the last permit cycle it appears that these changes to
the winter NH3-N values will not impact facility compliance. This is obviously an area of
change that should be reviewed closely as the new permit takes effect.
Modifications with Completion of Treatment System Updates — In August of 2019 She -Can
Company was issued an ATC to modify your treatment system and upgrade it to the permitted
capacity of 0.03MGD. It is our understanding that installation is complete and only some final
inspections remain before the upgraded system will be in operation. Since this process is not yet
completed, the draft permit still contains effluent discharge limits for phased discharge from
0.02MGD up to 0.03MGD. When the final permit is issued it is likely that this process will be
complete and the final permit will be written with discharge limits only for the final 0.03MGD
conditions. Please follow all the procedures outlined in your approved ATC including contacting
our Asheville Regional Office staff prior to operation of the new system so they can schedule an
onsite inspection.
With the current upgrade of your system you should be aware that it is likely that no future expansion of
your facility will be allowed due to the assimilative capacity of the receiving stream (Line Creek) being
taken up. To expand beyond your permitted flow of 0.03MGD would most likely require significant
reductions in your effluent limits, if an expansion would be considered at all. Feel free to contact us if
you wish to discuss this issue.
The NPDES standard conditions (Parts II, III, and M that are a part of the permit are not included in this
draft document (cover, map, and Part I). The conditions are the same as in your current permit. The latest
version of the standard conditions is available at https://bit.ly/3k5NFaL and can be viewed online or
downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having general
circulation in the Buncombe County area soliciting public comments on this draft permit. Please provide
any written comments you may have to me no later than 30 days after receipt of this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning this draft permit,
please call me at (919) 707-3629 or contact me by email at bradley.bennett@ncdenr.gov.
Sincerely,

Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)I
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: hops:Hdeg.nc.gov/about/divisions/water-resources/edmr.
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements may
be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3)
or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2025 the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).

Draft Permit NC0075680
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify
the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated
entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
https://www.federalre ig•ster.gov/documents/2015/10/22/2015-24954/national-pollutant-discharg_e-
elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must fast submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://deg.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
Page 6 of 8
Draft Permit NC0075680
http://deg.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall
make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief, true, accurate,
and complete. I am aware that there are significant penalties for submitting false information,
including the possibility of fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)l
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years from the
