EXPEDITED FACT SHEET - NPDES PERMIT DEVELOPMENT
NPDES Permit: NCO075680
2020 Renewal
This form must be completed by Permit Writers for all expedited permits which do not require full Fact Sheets.
Expedited permits are generally simple 100% domestics (e.g., schools, mobile home parks, etc.) that can be
administratively renewed with minor changes, but can include facilities with more complex issues (Special
Conditions, 303(d) listed water, toxicity testing, instream monitoring, compliance concerns).

FACILITY OVERVIEW:
This facility is 100% domestic waste. The application notes that the residential subdivision currently has 50
homes served. The design capacity of the treatment system as built is 0.02 MGD and consists of the following
wastewater treatment components:
• Bar screen
• Aeration tank
• Sludge holding tank
• Chlorine contact chamber
• Dechlorination
• Aerobic digester

Treatment System Upgrade
The permit includes a phased effluent limits page with a provision for expansion to 0.03 MGD. On August 22,
2019 the Division approved an Authorization to Construct for the Rosewood facility to modify the treatment
plant. The modifications will increase the capacity of the plant to 0.03 MGD to reach the permitted flow.
During the permit development process the permittee indicted that the facility modifications have been built
and they are currently awaiting a few final inspections before beginning to operate the modified system. They
anticipate that this will occur and the system will be operating by the end of the year.
Once the permittee begins operating the upgraded system the permit will no longer need the phased effluent
limits and the permit will operate at the 0.03MGD level. With the permit drafted and noticed with the phased
effluent levels, the permittee will be advised in the accompanying cover letter that with completion and
operation of the upgraded treatment system the final permit will reflect just the effluent level of 0.03MGD. The
upgraded treatment system will consist of the following components:
• Bar Screen
• Equalization Basin (accepting flow from two influent lines)
• Flow Control Box (will split flow to two separate treatment systems)
• 2/3 of Flow to Existing Aeration Basin and Existing Clarifier
• 1/3 Flow to New Aeration Basin and New Clarifier
• New Chlorination / Dechlorination Tank
• New Outfall Location (approx. 15 feet upstream of current discharge, still to Line Creek)
** Update After Public Notice: **
The treatment system upgrade has been completed. Asheville Regional Office staff conducted an inspection of
the new system on February 19, 2021 and confirms that the system is in place in accordance with their A to C.
With this change, the final permit has been adjusted to remove the tiered flow limits. The final permit only
contains the effluent flow limits for the 0.03 MGD flow.
Application Information
No modifications were noted or proposed in the current application but as noted above, the permittee is
currently upgrading the treatment system (Upgrade is complete).
Inspection Information
Most recent inspection (12/18/2018) noted that the facility should perform maintenance trimming to assure
access to the effluent pipe. The report also indicated the permittee was considering changes to the flow
measurement devices. Regional office staff recommended that in these reviews an overall review of other
system components should be conducted by the engineer as well.
COMPLIANCE:
This facility has not had an enforcement action since 2002. During the permit cycle the facility did have two
NOVs issued for fecal coliform exceedances, one in May 2017 and one in October 2018.

The data reviewed for the renewal is from November 2015 through August 2020.
NH3-N MONITORING:
Current Requirement: 2/ Month monitoring in Current Permit at 0.02MGD flow and Weekly for
0.03MGD flow. Permit has winter monthly average limits that are more
than 2 times the summer limit.
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 winter monthly average limits for NH3-N are being adjusted in the permit. This will
apply to the limits for both effluent pages (0.02 and 0.03).
The draft permit includes proposed changes to the winter limits. These changes will reduce the winter monthly
average limit from 20mg/L to 15.6 mg/L on the 0.02MGD effluent page and from 14mg/L to 11.0 mg/L on the
0.03MGD page. The daily max limits will remain unchanged at 35 mg/L for the 0.02MGD flow and 27.5mg/L for
the 0.03MGD flow. A review of the monitoring data over the permit cycle indicates that the highest winter NH3-
N value was 14 mg/L, so, no daily values exceeded the daily winter limits. There were no instances over the
last permit cycle (25 monthly values) where monthly averages would have exceeded the proposed monthly
average 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.
FILE HISTORY REVIEW SUMMARY
Waste Load Allocation(WLA) in 1988 for 0.03MGD flow established limits for BOD, TSS, Fecal and pH.
An Authorization To Construct (ATC) was issued in 1989 for a 0.02MGD treatment facility.
Waste Load Allocation in 1993 was done for the permitted flow of 0.03MGD and for the as -built flow of
0.02MGD. Ammonia limits (NH3-N) were added in this review. Waters at the time were classified WS-
IV and backup power was required for the 0.03MGD flow. This requirement has remained in the
permit.
This WLA notes that the drainage area in the earlier WLA was incorrect (1.1 acres rather than 0.69). The
drainage area change causes minor changes in the 7Q10 and other flow numbers but is noted as not having

a significant impact on the limit numbers. It still looks like the old numbers were used in all the
calculations and the old numbers are the ones shown in the BIMS flow data today. A review was done (Nov.
2020) of the discharge location using USGS StreamStats and it allears that the original drainage area is
more accurate (0.69 acres). So, it is probably okay that we have continued to use the original WLA flows
and numbers.
• 1995 Permit - limits added for NH3-N and monitoring added for Total Residual Chlorine (TRC). For
0.03MGD flow TRC limited.
• Two permit modifications were issued in 1996. In July a modification was issued to reduce the
monitoring frequency for BOD, TSS and Fecal to 2/Month. In October a modification was issued to
reduce NH3-N monitoring to 2/Month.
• 2001 Permit Renewal - Stream classification updated to reflect reclassification to Class C. The permit
was transferred to the current owner (She -Can Company) in July 2001.
• 2005 Permit Renewal - Daily Max limit added for NH3-N and limit added for TRC under the 0.02MGD
flow.
• In 2006 an ATC was issued for installation of a dechlorination system to meet the new limits.
• 2010 Permit Renewal - No Changes
• 2015 Permit Renewal - no major changes other than regulatory citations, etc.
• In August 2019 an ATC was issued for the construction of upgraded treatment components to move the
system to its permitted flow of 0.03MGD. Specifics of this addition have been discussed previously in
this Fact Sheet
The permitfile also contains two emails, one from 2012 and one from 2020 that discuss the potential impacts
of another discharge permit upstream on Line Creek (High Vista - NC0089095). These emails establish that
expansion of the Rosewood facility in the future would most likely result in a requirement to reduce ammonia
limits for the facility. The 2012 Fact sheet addendum for the High Vista permit notes that the Rosewood permit
has established discharge limits and will not be subject to limits revisions. The treatment system modification
that is currently under way for this facility is in keeping with previously established permit limitations and is
not subject to any limits modifications at this time. Any further expansion of this flow, however, will most likely
result in a necessary modification of permit limits to protect the receiving stream.
PROPOSED PERMIT CHANGES:
• Requires for eDMR were not included in the 2015 permit so this renewal has added in the most
recent eDMR requirements to be consistent with final EPA rules.
• Added regulatory citations throughout permit as needed.
• Updated NH3-N effluent limits to set winter limits at values that are no less stringent than 2 times
the summer values to be consistent with Division rules.
• Discharge outfall latitude/longitude updated for new location.
• Facility Location latitude/longitude updated (location of 2554 Brevard Road address).
• Update: 0.02MGD flow level removed with completion of upgraded treatment system (0.03MGD)

So, for Rosewood looks like sample type can remain as grab since they are at, but not over .003MGD. For the flow, let me know what you
think. If you guys feel they should move to continuous monitoring, then we can do that. Otherwise, we will leave it at instantaneous.

Sampling:
Until they exceed 0.03 MGD, they can collect grab samples. That's what the rule requires.

Subject: Monitoring Questions
Hey Charles,
Had a couple of quick questions for you. I have a renewal that currently has phased flows in the permit (0.02MGD and 0.03MGD). The
current permit has the flow measurement for both of these set at instantaneous. I have a document (21B .0505 Monitoring Requirements
Summary) that indicates Q> or = 0.01MGD requires continuous monitoring, but I didn't see that in the rule when I looked, maybe I missed
it. If I need to change this it would be nice to have a reference to where that is required. 213 .0505 seems to just require continuous
monitoring for all [ (b)(1)(A)) with the ability to allow other monitoring under (b)(1)(C). This permit has always had instantaneous for both
(at least dating back to 1993 which is the oldest permit I have). Maybe we had approved Instantaneous some time before and i just don't
have any documentation of it?
Second question is for the same renewal. The region also asked if the 0.03MGD limits should require composite monitoring instead of
grab. The same document I noted above says that Q> or = 0.03MGD - Composite. However, when I look at the rule it says Q< or =
0.03MGD = Grab (see language below). Does the summary need to be changed?
26 .0505 (c)(3)(B)
(B) Samples of the influent and effluent of the water pollution control facility or other point source shall be composite samples, except as provided in Part (C) of
this Subparagraph. Samples for facilities with design flows of 30,000 gallons per day or less shall be grab samples unless the Director determines that, due to such factors
as the variability of the discharge or its potential for impacts on the receiving stream, composite samples are necessary to characterize the discharge. The Director may
specify the type of sample and type of composite sampling required, in order to obtain representative samples.
Thanks for any guidance you can give on these!

Cover letter says Dear Mr. Bet instead of Best.
Not really liking the third sentence since there has been significant changes to their treatment system but since you have the last bullet in there about
the AtC then no matter.
In the third bullet (NH) you have "and have" in there twice.
I am not sure about the standby power question. I do know we'd want them to have it regardless and the AtC and plans state they will have it. The plans
however show it under #28 and says to refer to specifications but I do not see those specifications.

Subject: Rosewood MHP Draft Permit- NCO075680
Hey Linda,
Here is the draft permit for Rosewood MHP for your review. There are a couple of things that are a little strange with it. I have tried to
explain in the cover letter and in the Fact Sheet. Let me know if this all makes sense. So the issues are:
• They are in the process of their upgrade to reach their permit limit of 0.03MGD. The system is not yet operational so I have written
the draft for notice to still include the phase effluent pages as before. However, I noted in the cover letter that the upgraded system
will probably be in place before the renewal permit is effective (most likely March) so at that time the final permit will be written
without the phased flow and just have the 0.0311VIGD effluent page.
• The second issue is related to the assimilative capacity of Line Creek since High Vista is upstream. I have explained in the fact sheet
that they already had this approval and so they get the limits that have been in the permit (with the exception of the reduced winter
NH3-N limit to meet the rule). In the cover letter I have made them aware that it is possible that no further expansion will be allowed
or may come with reduction in effluent limits.
Take a look at all of this and let me know what you think.
Thanks

Maureen,
Here is the second permit renewal draft that I mentioned. This one is a little different so I wanted to point
something out to you and see if it leads to any changes for you guys. This permit has phased effluent flows
but they are currently in the process of upgrading their treatment system. Most Likely the new system will be
in place before the final permit is issued and we will write the permit just for the upgraded flow of 0.03MGD.
I wanted to check with you and see of the upgrade from 0.02 to 0.03MGD will change any of your
classifications for this treatment system or their operator needs.
Thanks for your input on this.

It was only moved about 15' from the original discharge point. To be accurate our surveyors are going to shoot an as -

Mr. Brooks,
Thanks for the plans and sorry to have to ask to have them resubmitted. I was wondering if you might have
Lat/Long for the new outfall point? If it is in the information and I missed it I'm sorry.

Hi Nathan,
I had another question for you. Since it looks like the new system will be in place before the
permit is finalized I wanted to see if you could provide me with an update of the treatment
system description for the permit. If you had a plan sheet that showed the overall components
that you could email that would help. Since we are working from home right now I unfortunately
don't have access electronically to any plans or drawings that were part of the Authorization to
Construct from 2019.
Thanks

Could you also please respond to this email to le t me know that you received the attached draft and were

Linda,
Sorry i forgot about this, but their winter number will drop a little to be in compliance with the 2B .0404 rule of not exceeding summer numbers by more than 2X.
However, based on the data from the last permit cycle it looks like they can meet those numbers. Here is what the changes would look like:
For 0.03 MGD
Parameter
Current Limits
New Limits
Monthly Avg
Daily Max
Monthly Avg
Daily Max
NH3-N - Summer
5.5 mg/L
27.5 mg/L
5.5 mg/L
27.5 mg/L
NH3-N — Winter
14.0 mg/L
35 mg/L
11.0 mg/L
35 mg/L
So the only change would be the winter monthly average dropping to 11. They did not report any single winter value over 8.1 in the last cycle so it seems they would be
okay.

If there is no change then go with it. This new WWTP cannot meet lower limits, that is why I asked. Please don't ask John, I am sorry I brought it up. It seems every time I ask a question
about my permits, I end up getting my permittees in a bad place.

I don't think they will since they previously had a phased permit that allowed them to go up to the 30,000 GPD that they will have once the new stuff goes online. The
permit already had more stringent limits for the expanded flow so those will kick in. I'll check, but I don't think we need to change the limits since they already had this in
the permit. I know this one is a little strange with High Vista and another discharge upstream so I'll make sure. What are you thoughts on this. You think I'm on the right
track?

Mr. Best,
I am currently reviewing the permit renewal request for the Rosewood Mobil Home Park. In reviewing the
application and other information I have a few questions that I wanted to pass along to you. These are
outlined below.
• First, you have signed the application for the permit renewal. Applications must be signed by the
appropriate Responsible Official for your facility. In our records Scott Shealy is listed as the
Owner/Responsible Official. You can be delegated signature authority to sign applications and other
permit documents, but our records do not include a Delegation of Signature Authority to you. We will
either need to have Mr. Shealy sign the application or receive a delegation for you to sign. I have
attached a template memo for the delegation if this is what you choose to do. You can have this signed
and scan and email it back to me. SEE ATTACHED SIGNED FORM.
• Second, I just wanted to get an update from you on any recent upgrades with the treatment system. I
know that you received and Authorization to Construct in August 2019 for changes to the system. Are
any of these upgrades in process at this point? THE NEW TREATMENT PLANT HAS BEEN INSTALLED AND
THEY ARE GETTING FINAL INPSECTIONS SOON BEFORE WE START IT UP. SHOULD BE BEFORE THE END
OF THE YEAR.
• Last I wanted to let you know that The Division of Water Resources is currently transitioning towards
electronic correspondence in order to provide more convenience, control, and security to our
permittees and assist them in processing their transactions. This will hopefully provide more efficient
service to our permittees and other partners and will allow us to more effectively process and track
documents. With this, we would like to ask you for your approval of the transmittal of documents
related to your permitting and related activities with the Division in an electronic format. Documents
will be emailed to the appropriate contact person(s) in your organization in a PDF format. YOU HAVE
MY PERMISSION. I CAN BE LISTESD AS THE CONTACT AND THIS EMAIL ADDRESS IS FINE TO USE.

Please respond to me through email with verification that transmittal of your documents in an
electronic manner is acceptable to you. ACCEPTABALE. If you have any questions, please feel free to
contact me. At this time contact through email is best since most of our staff are working out of the
office. If we need to set up a time for a phone call we can do that through email.
Thanks for your help on this.
