HI Nob,
I would like to inspect the Bridgewater and Rhodhiss facilities covered under NCG500102 and NCG500108 respectively.
Please check with the appropriate personnel and let me know what day works.
June 17, 18, 19, 22, 23 or 24.
The inspections tend to take —1.5-2 hours. I typically start my inspections around 9:30-10am. We can begin with
paperwork, then go through to the sampling locations where I likely would take samples. I would think we could do
both facilities in one day. I have an Environmental Monitoring Plan submitted to this office December 2007 describing
Duke's procedures for sampling. It indicates there is afield data hand recorded sheet used, then that information is
transferred to an excel spreadsheet. To save time you could send me the field data sheets and coinciding excel
spreadsheets for Bridgewater and Rhodhiss that way I could review some data at my office. You can send it to my email,
if that suits you, for the following dates: January 2014 thru present.

Monitoring at each facility shall be conducted only when hydroelectric generation is
occurring. Samples and in situ measurementsare to be collected from designated sites,
described herein, which will provide a characterization of effluent and receiving stream water
quality.
All field and laboratory methods shall conform to techniques approved for NPDES reporting,
and be performed by qualified personnel associated with a NCDENR-certified laboratory.
Temperature and pH are to be measured on site (see Appendices 1 through 15 for more
detailed description of specific sampling sites) utilizing a calibrated Hydrolab DataSondeo
(Duke Energy EHS Services Procedure 3210-2, or subsequent approved revisions). As
specified in the instrument operational procedure, both the temperature and pH measuring
subsystems are to be calibrated using National Institute of Standards and Technology (NIST)
references (i.e., NIST-certified precision thermistor, and NIST-certified pH buffer solutions).
Where practical from both logistical and safety perspectives, measurements will be collected
in situ, with instrument sensors placed within the effluent stream or waterbody at a depth of
0.3 meters (approximately 1 ft). In situations where in situ instrumentation cannot be
deployed due to site -specific logistical or safety constraints, temperature and pH will be
measured from a surface grab sample (exceeding a 4-liter volume) collected with a clean
stainless steel bucket or other suitable device. Under this exception, temperature and pH
measurements shall be made immediately after the sample is drawn.
Effluent samples to be collected for laboratory analyses shall be obtained following
applicable practices detailed in Duke Energy EHS Services Procedures 3290-1 and 3295-1,
or subsequent approved revisions. Samples for laboratory analyses of oil and grease are to be
collected from the air -water interface so as to capture any potential surface film. Oil and
grease samples shall be collected in glass containers with Teflon° -lined lids, acid -preserved
(112SO4 to <pH 2) and iced (< 4°C) on -site immediately following collection. Oil and grease
shall be analyzed by EPA method 1664A for hexane extractable material, or comparable
alternate method(s) as specified under NPDES regulations and/or NCDENR implementation
guidance.
Field data shall be recorded at the time determinations are performed directly on project -
specific field sheets (Appendix A16), or optionally recorded in an electronic form on a laptop
computer (Appendix A17). Station -specific hydroelectric combined flow coinciding at the
time of sampling shall be recorded on field records for the sampling date/time. Sample
chain -of -custody records shall be completed at the time of sample collection, as detailed in
Duke Energy EHS Services Procedure 3290-1, or subsequent approved revisions. Original
4

documents related to field and laboratory records shall be retained by Duke Energy for a
period of not less than five years.

Duke Energy's Rhodhiss Hydroelectric Powerhouse consists of Rhodhiss Dam; powerhouse, generation
equipment, powerhouse sumps and tailrace. The tailrace discharges to the Catawba River/Lake Hickory.
The plant has permitted discharges of generator thrust bearing cooling water (via hydraulic coolers) and
powerhouse sumps.
Mr. Keith Haynes, Ms. Starr Silvis and Mr. Larry Frost performed the inspection. The facility appeared to be
well maintained and operating properly. Thera were no un-permitted discharges noted during the inspection.
The purpose of the permit is to protect the receiving stream; therefore, the inspectors recommend that
Upstream. Effluent and Downstream sampling paints be re-evaluated for this facility_ The recommended
upstream sampling site is in Lake Rhodhiss at the powerhouse intake, the effluent site from the tailrace
(over the rail at the entrance to the powerhouse at a safe location) and the downstream (at a predetermined
safe access) site, possibly a pier at the sports bar. It is recommended that these sites be established by
written policy.
Once the sampling sites are established, then the monitoring requirements and monitoring frequency for
each site should re-evaluated. There must be flow for the sampling to be valid.
The proper reporting of flow from the powerhouse was discussed, during the inspection. The inspectors
recommend that Duke Energy use common units of measure for this industry (examples discussed were;
CF S and MGD however some other unit may be more appropriate) with regards to flow. If you should have
any questions regarding this issue please contact one of the inspectors.
Please note the inspectors comments regarding permitting.
Finally, thanks to Allen Stowe, Sawa Powell, Donald Cresswell and Nob Zalme for their assistance during the
inspection.

In that Renewal Duke ask for the permitting of 3 outfalls (001,002,and 003). During this
inspection this issue was discussed at length. The inspectors recommend:
Duke Energy submit an amended Notice of Renewal Intent for this facility and the
amended Renewal state only one discharge point (001).
This will keep this facility consistent with all other Duke facilities in the Asheville Region
of DWQ, prevent construction of additional monitoring facilities, prevent an increase In
monitoring and keep monitoring as simple as possible. You are welcome to attach this
inspection report to your amended Renewal as explanation.

Certificate of Coverage (CoC) NCG500108
Rhodhiss Hydroelectric Plant
Caldwell County
Dear Permittee:
The facility listed above is covered under NPDES General Permit NCG500000. NCG500000 expires
on July 31, 2007. Federal (40 CFR 122.41) and North Carolina (15A NCAC 2H.0105(e)) regulations require
that permit renewal applications must be filed at least 180 days prior to expiration of the current permit. If
you have already mailed a renewal request, you may disregard this notice.
To satisfy this requirement, the Division must receive a renewal request postmarked no later than
February 1, 2007. Failure to request renewal by this date may result in a civil penalty assessment. Larger
penalties may be assessed depending upon the delinquency of the request. This renewal notice is being sent
well in advance of the due date so that you have adequate time to prepare your application.
If any discharge previously covered under NCG500000 will occur after July 31, 2007, the
CoC must be renewed. Discharge of wastewater without a valid permit would violate North Carolina
General Statute 143-215.1; unpermitted discharges of wastewater may be assessed civil penalties of up to
$25,000 per day.
If all discharge has ceased at your facility and you wish to rescind this CoC [or if you have other
questions], contact me at the telephone number or e-mail address listed below.
Sincerely,
V44N7

In response to your renewal application for continued coverage under general permit NCG500000, the Division of
Water Quality (DWQ) is forwarding herewith the reissued wastewater general permit Certificate of Coverage
(COC). This COC is reissued pursuant to the requirements of North Carolina General Statute 143-215.1 and the

dated May 9, 1994 (or as subsquently amended).
The following information is included with your permit package:
* A copy of the Certificate of Coverage for your treatment facility
* A copy of General Wastewater Discharge Permit NCG500000
* A copy of a Technical Bulletin for General Wastewater Discharge Permit NCG500000
Your coverage under this general permit is not transferable except after notice to DWQ. The Division may require
modification or revocation and reissuance of the Certificate of Coverage. This permit does not affect the legal
requirements to obtain other permits which may be required by DENR or relieve the permittee from responsibility

Subject: NPDES Wastewater Permit Coverage Renewal
Rhodhiss Hydroelectric Plant
COC Number NCG500108
Caldwell County
Dear Permittee:
Your facility is currently covered for wastewater discharge under General Permit NCG500000. This permit expires
on July 31, 2002. Division of Water Quality (DWQ) staff is in the process of rewriting this permit with a
scheduled reissue in the summer of 2002. Once the permit is reissued, your facility would be eligible for continued
coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the DWQ for renewal of
your permit coverage. To make this renewal process easier, we are informing you in advance that your permit
coverage will be expiring. Enclosed you will find a general permit coverage renewal application form. This
will serve as your application for renewal of your permit coverage. The application must be completed and
returned with the required information by February 01, 2002 in order to assure continued coverage under the
general permit. There is no renewal fee associated with this process. Your facility will be invoiced for the annual
permit fee at a later date.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of wastewater from your facility
without coverage under a valid wastewater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
If the subject wastewater discharge to waters of the state has been terminated, please complete the enclosed
rescission request form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit coverage renewal procedures please contact the Asheville Regional
Office at 828-251-6208 or Delonda Alexander of the Central Office Stormwater Unit at [phone], ext. 584

5. Mass/Day Measurements
a. The "monthly average discharge: is defined as the total mass of all
daily discharges sampled and/or measured during a calendar month on
which daily discharges are sample and measured, divided by the number
of daily discharges samples and/or measured during sncli month. It is
therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by
the number of days the tests were reported. The limitation is
identified as "Daily Averages' or "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total. mass of
all daily discharges'sampled and/or measured during the calendar week
(Sunday -Saturday) on. which daily discharges are sampled and measured,
divided by the number of daily discharges samples and/or measured
during such week. It is, therefore, an arithmetic mean found by
adding the weights of pnllut.ants found each day of the week and then
dividing this sum by the number of days the tests were reported. This
limitat.i.on is identified as "Weekly Average" in Part I of the permit.
C. The "maximum daily discharge" is tha total truss (weight.) of a
prllutarit discharged during a calendar day. If only c; ;.c, sample is
taken during any calendar day the weight of polluta.rrt calculated from
it is the "maximum daily discharge." This limitation is identified as
"Daily Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all
daily discharges sample and/or measured during the calendar year- on
which daily discharges are sampled and measured, divided by the number
of daily discharges sampled and/or measured during such year.. It is,
therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the year and there dividing this stun by the
number of days the tests were reported. This limitation is defined as
"Annual. Average" in Part I of the permit.

Part lI
Page 12 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform
bacteria, is the sum of the concentrations of all daily discharges
samples and/or measured during a calendar month on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled
and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value -is equal to the
concentration of a composite sample or in the case of grab samples is the
arithmetic mean (weighted by flow value) of all the samples collected
during that calendar day. The average monthly count; for fecal coli-form
bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" or
"Daily Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria,
is the sum of the concentrations of all daily disclinrges sampled and/or
measured during a calendar week (Sunday/Saturday) on which daily discharges
are sampled and measured divided by the number of daily discharges sampled
and/or measured during such week (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the
arithmetic mean (weighted by flow value) of all the samples collected during
that calendar day. The average weekly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar
week. This limitation is identified as "Weekly Average" under "Other
Limits" in Part I of the permit.
C. The "maximum daily concentration is the concentration of a pollutant
discharge during a calendar day." It is identified as "Daily Maximum"
under "Other Limits` in Part T of thee permit.
d. The "average annual concentration," other than for fecal coliform bacteria,
is the sum of the concentrations of all daily discharges sampled and/or
measured during a calendar year on which daily discharges are sampled and
measured divided by the number of daily discharges sampled and/or measured
during such year (arithmetic mean of the daily concentration values). The
daily concentration value is equal to the concentration of a composite
sample or in the case of grab samples is the ar_i.t:hmeti.c mean (weighted by
flow value) of all the samples collected during that calendar day. The
average yearly count for fecal coliform bacteria is the geometric mean
of the counts for samples collected during a calendar year. This limitation
is identified as "Annual Average" under "Other. Limit-," in Part I of the
permit.

Part II
Page 13 of 14
7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours '
average flow, averaged monthly. It is determined as the arithmetic mean
of the total daily flows recorded during the cal.endar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time
of sampling, when both the sample and flow will be representative of the
total discharge.
8- Types of Samtles
a. Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flow, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent grab
samples shall be no greater than hourly. Intervals between effluent grab
samples shall be no greater than hourly except where the detention time
of the wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days; provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or less.
b. Grab Sample: Grab samples are individual samples collected over a
period of time not exceeding 15 minutes; the grab sample can be taken
manually.
9. Calculation of Means
a. Arithmetic Mean: The arithmetic mean of any set of values is the summation
of the individual values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of
the product of the individual values where N is equal to the number of
individual values. The geometric mean is equivalent to the antilog of
the arithmetic mean of the logarithms of the individual values. For
purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).
C. Weighted by Flow Value: Weighted by flow value means the summation of eacli
concentration times its respective flow divided by the summation of the
respective flows.

10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight
of the next day. However, for purposes of this permit, any consecutive 24-hour
period that reasonably represents the calendar day may be used for sampling.

Subject: NPDES PERMIT NO. NC0004529
CALDWELL COUNTY
Dear Permittee:
The subject permit issued on 1/03/89 expires on 12/31/93. North
Carolina General Statute (NCGS) 143-215.1(c) requires that an
application for permit renewal be filed at least 180 days prior to the
expiration date. As of the date of this letter, the Division of
Environmental Management had not received an application for renewal.
If operation of a discharge or waste treatment facility is to occur
after the permit's expiration date, or if continuation of the permit is
desired, it must not be allowed to expire. A renewal request must be
submitted no later than 180 days prior to the permit's expiration date.
Operation of the waste treatment works or continuation of a discharge.
after the expiration date would constitute a.violation of NCGS 143-215.1
and could result in assessment of civil penalties of up to $10,000 per
day. If continuation of the permit is desired, failure to request
renewal at least 180 days prior to expiration will result in -a civil
assessment of at least $250.00; larger penalties may be assessed
depending upon the delinquency of the request.
A renewal application shall consist of the following information:
1. A letter requesting the renewal.
2. The completed application form (copy attached), signed and
submitted in triplicate, referenced in Title 15 of North Carolina
Administrative Code (15A NCAC) Subchapter 2H .0105(a).
3. A processing fee (see attached schedule) in accordance with 15A
NCAC 2H .0105(b). The application processing fee is based on the
design or permitted flow, whichever is appropriate, listed in the
first categories of facilities.
4. Primary industries listed in Appendix A of Title 40 of the
Code of Federal Regulations, Part 122 shall also submit a
priority pollutant analysis in accordance with Part 122.21.

F
A
5. Facilities which have not been constructed within the last
permit cycle and are therefore, considered "new" facilities,
shall also submit an Engineering Alternatives Analysis,
referenced in 15A NCAC Subchapter 2H .0103 and Subchapter
2B .0201(c).
6. If the facility covered by this permit contains some type of
treatment works, a narrative description of the sludge management
plan must be submitted with the application for the renewal.
In addition to penalities referenced above, a permit renewal
request received after the expiration date will be considered as
a new application and will require the higher application fee.
15A NCAC 2H .0105(b)(2) requires payment of an annual
Administrative and Compliance Monitoring fee for most permitted
facilities. You will be billed separately for that fee (if
applicable), after your permit is approved.
The letter requesting renewal, the completed Permit application,
and appropriate fee should be sent to:
Permits and Engineering Unit
Division of Environmental Management
Post Office Box 29535
Raleigh, North Carolina 27626-0535
The check should be made payable to the North Carolina Department of
Environment, Health, and Natural Resources which may be abbreviated as
DEHNR.
If there are questions or a,need for additional information
regarding the permit renewal procedure, please contact me or any
individual in the NPDES Group at telephone number [phone].

Washington
919/946-6481 Thank you for your letter dated October 7, 1992, requesting rescission
of NPDES Permit No. NC0004529. I have received information from the
Wilmington Asheville Regional Office which indicates that the subject facility may still
919/395-3900 discharge to surface waters of the state. Although the information indicates
Winston-Salem that the water cooled transformers have been replaced by air cooled
919/896-7007 transformers, there still exists a cooling water discharge from three turbine
thrust bearings. Due to the potential to discharge oil to surface waters, it will
be necessary to maintain NPDES Permit No. NC0004529.
Please be advised that renewal of NPDES Permit No. NC0004529 must
occur at least 180 days prior to permit expiration. If you have any questions
concerning this decision, please contact Mr. Forrest Westall or Mr. Paul White
in our Asheville Regional Office at 704/251-6208.

I visited the subject facility on October 23, 1992, and
found that the three water .cooled transformers had been
replaced by air cooled transformers and that the water
lines had been physically disconnected. However, it is
recommended that the permit remain intact due to the
discharge of once through cooling water from three turbine
thrust bearings. The cooling water cools the tub of
lubricating oil at the top of each of the three generators.
The water is discharged into the tail races.
If you have any questions, please let me know.

��
Singer Furniture Company
Caldwell County NC
Dear Mr. Day:
Reference is made to your May 16, 2002 request for rescission of the subject NPDES General Permit. In
your letter you state that the facility is closed. Therefore, in accordance with your request, NPDES General Permit
No. NCG510343 rescinded, effective immediately.
Please be advised that this permit rescission is based wholly upon your statement that the activities which
would require general permit coverage at the site have ceased or been eliminated. Division staff has not visited the
site to obtain independent verification. If in the future you wish to again discharge wastewater to the State's
surface waters, you must first apply for and receive a new NPDES Permit. Operating a facility, discharging
wastewater or discharging specific types of stormwater to waters of the state without a valid NPDES Permit will
subject the responsible party to a civil penalty of up to $25,000 per day. Enforcement action will be certain for
person that have voluntarily relinquished permit coverage when, in fact, continuing permit coverage was necessary.
If, in retrospect, you feel the site still requires permit coverage, you should notify this office immediately.
Furthermore, if in the future you wish to again discharge to the State's surface waters, you must first apply for and
receive anew NPDES permit.
If the facility is in the process of being sold, you will be performing a public service if you would inform the
new or prospective owners of their potential need for NPDES permit coverage.
You have questions about this matter, please contact Marcia Lieber at [phone], 530 or the Water
Quality staff in our Winston-Salem at [phone].

Alan W. Klimek, P.E.

Dear Mr. Crump:
In accordance with the application for discharge, the Division is forwarding herewith the subject
certificate of coverage to discharge under the subject state - NPDES general permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated December 6, 1983.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to request an individual permit by submitting an individual permit
application. Unless such demand is made, this certificate of coverage shall be final and binding.
Please take notice that this certificate of coverage is not transferable except after notice to the Division
of Environmental Management. The Division of Environmental Management may require modification or
revocation and reissuance of the certificate of coverage.
This permit does not affect the legal requirements to obtain other permits which may hC rcyutreU by HILc
Division of Environmental Management or permits required by the Division of Land P�csuur" >, C ;.:,t,,;
Management Actor any other Federal or Local governmental permit that may be required.
This letter also grants an Authorization to Construct for the subject project. Final plans and
specifications for the subject project have been reviewed and found to be satisfactory. Authorization is hereby
granted for the construction and installation of the proposed groundwater remediation treatment system and all
necessary appurtenances with discharge of treated wastewater into an unnamed tributary to Burnt Mill Creek in
the Cape Fear River basin.
This Authorization to Construct is issued in accordance with Part II, Section 2 of NPDES Permit No.
NC510000 issued March 30, 1994 and shall be subject to revocation unless the wastewater treatment facilities
are constructed in accordance with the conditions and limitations specified in Permit No. NCG510000.
Any sludge generated from this treatment facility must be disposed of in accordance with G.S. 143-
215.1 and in a manner approved by the North Carolina Division of Environmental Management.

In the event that the facility fails to perform satisfactorily, including the creation of nuisance conditions,
the Permittee shall take immediate corrective action, including those as may be required by this Division, such
as the construction of additional or replacement wastewater treatment or disposal facilities.
The Asheville Regional Office, telephone number [phone], shall be notified at least forty-eight
(48) hours in advance of operation of the installed facilities so that an in -place inspection can be made. Such
notification to the regional supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00
p.m. on Monday through Friday, excluding State Holidays.
Upon completion of construction and prior to operation of this permitted facility, a certification must be
received from a professional engineer certifying that the permitted facility has been installed in accordance
with the NPDES Permit, this Authorization to Construct and the approved plans and specifications. Mail the
Certification to the Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the life
of the facility and one (1) set of approved plans and specifications is being forwarded to you.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Fnvironmental TNTanagement in NTO ,,,
Carolina General Statute 143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from complying with
any and all statutes, rules, regulations, or ordinances which may be imposed by other government agencies
(local, state, and federal) which have jurisdiction.
Examination of the groundwater treatment system indicated that the system should adequately treat the
contaminated groundwater so that the effluent meets all NPDES permit limits. Naphthalene in the
groundwater may present a potential problem. Examination of the treatment system appeared to indicate that
this compound may have a tendency to saturate the activated carbon, thus causing breakthrough in 17 days.
Therefore, the Permittee should inpsect the viability of the carbon units on weekly, or twice per month, basis.
If you have any questions or need additional information, please contact Paul Clark at telephone
number [phone], extension 580.

Dear Permittee:

Subject: NPDES Wastewater Permit Coverage Renewal
Singer Furniture Company
COC Number NCG500063
Caldwell County
Your facility is currently covered for wastewater discharge under General Permit NCG500000. This permit expires
on July 31, 2002. Division of Water Quality (DWQ) staff is in the process of rewriting this permit with a
scheduled reissue in the summer of 2002. Once the permit is reissued, your facility would be eligible for continued
coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the DWQ for renewal of
your permit coverage. To make this renewal process easier, we are informing you in advance that your permit
coverage will be expiring. Enclosed you will find a general permit coverage renewal application form. This
will serve as your application for renewal of your permit coverage. The application must be completed and
returned with the required information by February 01, 2002 in order to assure continued coverage under the
general permit. There is no renewal fee associated with this process. Your facility will be invoiced for the annual
permit fee at a later date.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of wastewater from your facility
without coverage under a valid wastewater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
If the subject wastewater discharge to waters of the state has been terminated, please complete the enclosed
rescission request form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit coverage renewal procedures please contact the Asheville Regional
Office at 828-251-6208 or Delonda Alexander of the Central Office Stormwater Unit at [phone], ext. 584
