Dear Mr. Mickelson:
The Wilmington Regional Office received a complete, modified Stormwater Management Permit
Application for The Village at Mayfaire on October 10, 2011. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding modified Permit No. SW8
011119 dated October 12, 2011, for the construction, operation and maintenance of the BMP's and
built-upon areas associated with The Village at Mayfaire.
This modification revises Section III of the permit, the Monitoring Requirements. A new sampling
location map has been approved and is added to the plans previously approved on December 4, 2002,
which remain in effect.
This permit shall be effective from the date of issuance until December 4, 2012, and shall be subject to
the conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right
to request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings
(OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes,
and must be filed with the OAH within thirty (30) days of receipt of this permit. You should contact the
OAH with all questions regarding the filing fee (if a filing fee I required) and/or the details of the filing
process at: 6714 Mail Service Center, Raleigh, NC 27699-6714, or Telephone [phone] or visit
their website at www.ncoah.com.

III. MONITORING REQUIREMENTS
1. "BMP" means the entire approved Best Management Practice, including any
combination of individual practices, such as a wet pond and an infiltration area,
the outlet structure, level spreaders and vegetated filter strips.
2. Analytical monitoring of the BMP's shall be conducted quarterly. First flush inflow
and outflow grab samples shall be obtained at the location(s) shown on the
approved sample location site map.
3. BMP samples shall consist of a grab sample of the first flush inflow at the end of
the force main where it delivers the pumped runoff from the wet ponds into the
infiltration basin, and the infiltrated outflow from the monitoring wells. The first
flush inflow sample window is within the first 30 minutes of a discernable inflow
from a representative storm event. The discharge outflow sample window is at
least 1 day after the end of a representative storm event, but no later than 3 days
after the end of the representative storm event. Samples must be collected in
each quarter of each year of the permit for a total of 8 representative sample
events.
4. A quarterly physical, visual inspection of the system during a 1.5" design storm
rain event shall be conducted and may or may not be concurrent with the grab
sample collection. The purpose of the inspection is to evaluate and document
the system's ability to meet the permit conditions to contain the design storm
without discharging. For appropriate system evaluation, the beginning water
level in the storage ponds should be close to the Permanent Pool Elevation.

5. Monitoring parameters shall include, at a minimum, the below-listed items, a. - d.
Additional monitoring parameters may be required later to address water quality
issues in the affected area.
a. Total Suspended Solids
b. TKN as N
c. Total P
d. TPH Gasoline Range
6. The permittee shall split samples with the DWQ for at least one sample event
per year, at the discretion of the Division. The permittee shall make
arrangements with Regional Office staff to deliver the samples to a certified
laboratory of the State's choosing.
7. All samples shall be collected from a representative storm event. A
representative storm event is an event that measures greater than 0.1 inches of
rainfall and that is preceded by at least 72 hours during which no storm event
measuring greater than 0.1 inches has occurred. A single storm event may
contain up to 10 consecutive hours of no precipitation. For example, if it rains for
2 hours without producing any collectible discharge, and then stops, a sample
may be collected if a rain producing discharge begins again within the next 10
hours. The storm event date, total rainfall and duration must be recorded for both
the storm event prior to the sampled event and the sampled event.
8. All samples shall be delivered to a State certified laboratory for analysis. All
sampling results shall be submitted to NCDENR within 30 days of receiving the
laboratory results. All submitted data shall reference the project name, location,
and permit number. Results must be submitted to:
NCDENR-DWQ
Stormwater and General Permits Unit
1617 Mail Service Center
Raleigh, NC 27699-1617

NCDENR-DWQ
Wilmington Regional Office
127 Cardinal Drive Extension
Wilmington, NC 28405.
9. The permittee may petition DWQ to have monitoring requirements modified,
reduced, or eliminated if a minimum total of 8 representative storms have been
sampled for each BMP. A facility may opt to monitor more frequently than
quarterly as long as the data is collected over the course of at least one full year
with samples collected in each season. A request to modify, reduce or eliminate
monitoring requirements shall be evaluated on a case-by-case basis.
10. The permittee shall submit and maintain as part of the permit documents, a
monitoring station site map designating all sampling point locations as agreed to
by the permittee and the Division.

This is a draft of the new monitoring requirements that will go into the permit. I will also be adding a
requirement for visual observation of the system during a 1.5" rain event, with the rain starting when the
storage ponds are at the PPE and begin pumping to the infiltration basin immediately, to confirm that the
system does not discharge to surface waters during the 1.5" event.
I need 2 copies of a proposed sample location/monitoring station map from you, showing the inflow sample
location(s), which would be the point(s) where the force main dumps into the infiltration basin, and the outflow
sample location(s) at the proposed new monitoring well location(s).

Subject: RE: Mayfaire Sampling Protocol
Tammy and Larry:
The sampling for Mayfaire has finally been worked out. It's a little different than what we were originally
planning. I discussed the situation at length with our NPDES and ambient monitoring staff, supervisors
and Central office staff. We all agreed that sampling the individual BMP bypassed runoff was probably
not going to get us what we wanted.
The original intent of the sampling was to make sure the BMP's were functioning as designed to protect
Howe Creek. The systems for The Village and for the Town Center are similarly designed. They both
are required to capture and treat the design storm without discharging to surface waters. They both
utilize a wet pond for storage of the design storm, which then directs that design storm runoff to an
infiltration area and allows excess design storm to overflow through a vegetated filter. The difference is
that The Village uses pumps to get from the pond to the infiltration area to the bypass and the Town
Center uses gravity.
The quarterly sampling reports were reviewed by our ambient monitoring and NPDES staff people. As a
result, we are recommending quarterly sampling for at least 2 years.
1. Samples will be pulled for the first flush runoff into each wet pond storage area either at the last
catch basin, or the forebay, or at the end of the forcemain where it dumps into the infiltration
basin (The Village)—whichever is most convenient and accessible. This will allow us to know
the quality of the incoming runoff before it gets to the infiltration basin.
2. We are also recommending the installation of a monitoring well within each permitted infiltration
area. Depending on the size of the infiltration area, more than 1 well may be needed. Samples
of the water that is infiltrating will be pulled from the wells and analyzed to allow us to know the
quality of the water that is being infiltrated.
i

3. We are recommending the elimination of the fecal coliform monitoring only if more dog "pooper-
scooper" bag and disposal stations are added at strategic points where the dog-walkers will
have better access to them.
4. We are recommending that the upstream and downstream sampling of Howe Creek continue
(Town Center only),
5. We are eliminating the requirement to sample the ponds that drain to Bradley Creek (Town
Center).
Sampling will be for TSS, hydrocarbons, nitrogen and phosphorous. This should be less costly to the
permittee than the current protocol. At the end of 2 years the permittee can again request to eliminate
the sampling. Depending on the results, the Division may or may not elect to eliminate.
A request to modify the permit to change the monitoring requirements will require a $505.00 fee and a
new application. No new supplements or new signed O&M's will be required —the current ones will be
good.

Attached for your review and approval is the original and one copy of the permit modification
application, and check for$505.00. I did not include plans, BMP supplements, O&M agreements, deeds,
etc.as they are not a part of the modification and current copies are in your files.
The permit modification request is for water quality sampling protocol changes as outlined in your e-
mail on August 9, 2010. We will sample at the discharge points of the three detention pond force mains
into the infiltration basin (3 samples) and from a new monitoring well in the infiltration basin (1 sample)
on a quarterly basis for at least two years. Samples will be analyzed for TSS, hydrocarbons, nitrogen,and
phosphorus.
Please contact me if you have any questions or concerns.

Subject: Sampling Requirements
Tammy & Scott:
I have requested more information from our folks in Raleigh regarding the sampling requirements at Mayfaire.
My main concern is the reluctance on the part of the permittee to accept the new monitoring. The only
alternative to not accepting the new monitoring parameters is to keep the current monitoring as is with no
changes. This seems counterintuitive.
I understand your concerns about the "open-ended" feeling of the permit monitoring requirements, but I believe
that the new inspection schedule and sampling parameters will provide a very good indication as to the
effectiveness of the BMP's. The plan is to monitor for an additional 2 years only and then evaluate the data to
see if any data points to better or worse water quality.
There are certain benchmarks for various pollutants that can't be exceeded in stormwater runoff, but these
benchmarks are usually applied to industrial stormwater permits, not state stormwater permits. I really don't
think you want to have those benchmarks placed into the permit because failure to meet those benchmarks
may result in the permittee being required to do even more stormwater treatment and continued monitoring.
You may feel that a benchmark is better than having nothing at all to compare to—I don't think so in this case.
It is my understanding that the intent of the monitoring was to determine if the permitted BMP's were effective. I
think the original intended unwritten benchmark was that if water quality wasn't any worse afterward, then the
BMP's were probably effective. Perhaps the previous reports need to be re-evaluated from that standpoint. I'm
not convinced that the previous monitoring has demonstrated this, thus the need to look at making changes to
see if we can find the inspection and monitoring protocol that will provide acceptable data to make this
determination. I think this is what will get the permittee out from continued monitoring requirements once the 2
years is up.
I am agreeable to the placement of monitoring wells in locations around the infiltration basins that will provide
for an accurate representation of the treated runoff and will be easily accessible for sampling. If they are to be
placed outside of an infiltration area, it will be on the downslope side, close to the edge of the basin, as far
horizontally and vertically above the stream as possible. The bottom of the well will be no lower than 2 feet
below the bottom of the infiltration basin it is intended to sample. We don't want samples of the groundwater
below the SHWT—we want samples of the infiltrated runoff. All proposed well locations will be agreed upon
and approved by the Division before issuing the permit.
I'll let you know what if any recommendations that Raleigh staff has to add to this protracted discussion.

Subject: Mayfaire Sampling
All:
This issue with the sampling parameters at Mayfaire has really gotten out of hand. This is the current permit condition for sampling
parameters:
4. Monitoring parameters shall include,at a minimum,the below-listed items, a. -h.Additional monitoring parameters may be
required later to address water quality issues in the affected area.
a. Total Suspended Solids e. Temperature
b. Turbidity f. Conductivity
c. Fecal Coliform g. Flow
d. Dissolved Oxygen h. pH
Notice that it says additional monitoring parameters may be required later.The permittee requested to eliminate the sampling,but they
based their request on their belief that the sampling wasn't producing any real results. No conclusion as to the effectiveness of the
BMP's could be drawn.Our new proposal is to change the sampling locations and sample for the following:
1. Turbidity
2. Residue: Suspended,Volatile and Fixed
3. TKN as N
4. Total P
5. TPH Gasoline Range
They want some kind of"target" value or limit for these parameters in the permit,but I don't think they realize what they are asking
for.They don't like the fifth one for TPH. Our response to date has been that the permit allows us to add monitoring parameters.This
is all new to me. Bradley had indicated previously that the point of the Mayfaire sampling requirements was to evaluate the
effectiveness of the BMP's. Are these sampling parameters adequate to accomplish this? Do we change something else, drop
something,add something?
They also want us to put a time cap on the monitoring.I guess it costs a lot of money and they want some assurances that it will not go
on indefinitely.
Thanks for any input.

Subject: RE: Mayfaire Sampling Protocol
Tammy:
I've read your August 12, 2010 letter, and have the following comments:
1. I agree that dilution of the sample is not what we want, so we would restrict the sample location to the
one inlet or last catch basin only.
2. I agree that where there are multiple inlet points, a sample from each one could be pulled and
composited. Except for Pond #3 with the long forebay, most of the ponds in Mayfaire have only one
ultimate inlet, so I don't think this is a big problem. However, due to relatively flat grade, many systems
are designed such that the pipes are surcharged at all times, meaning that unless you catch the sample
as it falls into the catch basin, any sample taken from the water flowing at the bottom of the last catch
basin is probably diluted from the backed up forebay water already.
3. I understand your comment about the monitoring wells being located within the basin. I'll check with our
hydro-geologist, but I disagree that a monitoring well within the infiltration basin itself will contain a
quality of water that is the same as what exits the pond. If the well is constructed such that the
openings are 2 feet below the bottom, I would anticipate that the water collected from it will be what has
infiltrated through the 2 feet of infiltration media before working its way over to the creek. I'm not sure if
it is appropriate to pull samples from a well located outside of the basin area as that is not in the
treatment area. I'm not opposed to locating the well just outside of the edge of the basin if it will be
more convenient to access, but not outside of the property boundary and not next to the stream.
4. The current permit allows that additional monitoring parameters may be required later to address water
quality issues in the affected area. We understand that the system is not designed to treat for
hydrocarbons or phosphorous, but since they are generated by the parking lots and grassed areas of a
commercial development, we have added these 2 parameters and removed 7 other-parameters
including temperature, conductivity, flow, pH, DO, turbidity and fecal coliform. I think that's a fair
exchange. We understand and agree that the systems were not designed to treat for the new
parameters or for those 7 previous parameters. You have to remember that this is the ORW waters of.
Howe Creek and that Mayfaire is a unique kind of permit.
5. Although the initial request was to eliminate monitoring, the Division has determined that more relevant
monitoring is needed. The Division has read all of the monitoring reports that have been submitted. No
obvious trends could be discerned as the data were all over the place. We need for the new monitoring
to be conducted for at least 2 years to see if any trends can be identified. At the end of that 2 years, as
previously stated, we will again entertain a request to eliminate the monitoring.
Thanks,
Linda

originally planning. I discussed the situation at length with our NPDES and ambient monitoring staff,
supervisors and Central office staff. We all agreed that sampling the individual BMP bypassed runoff
was probably not going to get us what we wanted.

Subject: PROPOSED REVISED MONITORING PROTOCOL
Permit No.SW8 010512 Renewal
Mayfaire Town Center (Phase 1)
Dear Ms.Lewis:
This letter is in response to DWQ's recommended revised sampling protocol that you provided via email
on August 9,2010. The revised DWQ protocol is numbered and outlined below,followed by
concerns/comments provided by Total Stormwater Solutions,Inc. (TSS)on behalf of Mayfaire
Management Company,LLC(Mayfaire).
1. Samples will be pulled for the first flush runoff into each wet pond storage area either at the last
catch basin,or the forebay—whichever is most convenient and accessible.
TSS response:
The above recommendation will not allow for accurate influent sampling,as the sample
becomes diluted by the water that exists in the pond before the monitoring event. The influent
has to be collected inside of the catch basin(s)prior to entering the pond or forebay in order
to achieve accurate, non-diluted results. Further, we believe samples should be collected
from each concentrated inflow point(catch basin,pipe,flume, swale, etc.)for each respective
system and combined into a composite influent sample, as using one sample point could
result in varying results depending on traffic, environmental conditions, etc..
2. We are also recommending the installation of a monitoring well within each permitted infiltration
area.Depending on the size of the infiltration area,more than 1 well may be needed. Samples of
the water that is infiltrating will be pulled from the wells and analyzed to allow us to know the
quality of the water that is being infiltrated.
TSS response:
The monitoring wells have to be located outside of the infiltration basins, halfway
between the basin edge and the receiving stream in order to accurately assess the entire
system's function. The recommendation of installation of a monitoring well inside of the
infiltration basin completely ignores the treatment provided by the infiltration basin and
essentially serves no purpose, as the water that would be sampled by such a well is
essentially the same as water that exits the pond. Also, multiple wells are needed in
order to ensure the effluent sample is truly representative of the system's capacity as
opposed to a single well that may be unknowingly installed in some form of geologic
anomaly that produces outlier effluent results.

3. We are recommending the elimination of the fecal coliform monitoring only if more dog"pooper-
scooper"bag and disposal stations are added at strategic points where the dog-walkers will have
better access to them.
TSS response:
We concur. Mayfaire has already ordered pet waste removal stations to be
installed at strategic locations throughout the property.
4. We are recommending that the upstream and downstream sampling of Howe Creek continue
(Town Center only).
TSS response:
We concur and propose that Howe Creek upstream and downstream samples be
collected concurrent with the BMP outflow sampling from wells installed as
recommended above.
5. We are eliminating the requirement to sample the ponds that drain to Bradley Creek(Town
Center).
TSS response:
We concur.
6. Sampling will be for TSS,hydrocarbons,nitrogen and phosphorous.
TSS response:
We concur with continued TSS sampling. However, the BMPs that serve this site were
not specifically designed to treat hydrocarbons or phosphorus, so we do not concur with
adding any new monitoring parameters after five and a half years of collecting and
submitting extensive data to DWQ as specified per the original permit. If there are
additional justifications and/or facts that warrant the inclusion of additional and
dfferent data parameters in the testing protocol,please forward these for our review.
7. Quarterly sampling for at least 2 years.At the end of 2 years the permittee can again request to
eliminate the sampling.Depending on the results,the Division may or may not elect to eliminate.
TSS response:
We do not concur with the two year minimum requirement. Mayfaire has diligently
performed the required monitoring, and provided the required quarterly reports to DWQ
for data collected since December 2004. This five and a half years of data compiled by
tests specifically outlined by DWQ(including parameters, timing and sampling locations)
have been provided by Mayfaire to DWQ without any feedback, mentions of concern over
the data, or mentions of concern over the methodology of gathering the data. This makes
the decision to continue testing appear somewhat arbitrary without the inclusion of a
clear performance standard that would trigger the elimination of testing. It is our
opinion that elimination of sampling requirements is justifiable after four(4) results that
are consistent with the permit requirements,are achieved.
8. A request to modify the permit to change the monitoring requirements will require a$505.00 fee
and a new application.No new supplements or new signed O&M's will be required—the current
ones will be good.
TSS response:
Mayfaire will submit a permit modification request.

We sincerely appreciate your review and consideration of our request to eliminate all monitoring for
Mayfaire Town Center,and are thankful for your elimination of a majority of the original monitoring
parameters. We continue to be baffled,however,by the recommended methodology of gathering the
samples. We respectfully request that DWQ staff take a second look at our proposed monitoring protocol
(outlined in our June 18, 2010 letter addressed to Ms. Georgette Scott, and attached to this letter as
reference),which outlines,in a more scientifically appropriate manner,the how's and why's of collecting
the data as we recommended.
Please do not hesitate to call or email us with any questions. I can be reached at 910.622.7844,and Scott
can be reached at 919.669.0329.

Proposed BMP Monitoring Protocol:
• Total Suspended Solids shall be the only parameter sampled.
• Three(3)monitoring wells shall be installed at each infiltration basin(Basins 2,3 and 4)
halfway between each infiltration basin and its receiving creek or stream.
• Grab samples shall be collected from each concentrated inflow point(pipe,flume,swale,
etc.)for each respective system and combined as a composite sample representative of each
BMP system.
• Samples from the monitoring wells shall be pulled approximately 3-10 days after a
representative storm event.
• Monitoring requirements will be automatically eliminated if and when the first four events
sampled illustrate achievement of the design target of 90% TSS reduction.
For BMP systems,we propose the monitoring protocol be modified to more accurately illustrate the
efficacy of each BMP. We propose that this be completed by installing 3 monitoring wells at each
infiltration basin(Basins 2, 3 and 4—Pond 1 discharges to Infiltration Basin 2;for a total of 9 wells)
with wells located approximately halfway between each infiltration basin and its receiving creek or
stream. Samples for total suspended solids shall be pulled approximately 3-10 days after a representative
storm event,allowing time for the entire BMP system to perform its design function. Actual lag time
between inflow sampling and outflow sampling from the proposed monitoring wells will be calculated
more precisely upon your approval of this revised monitoring protocol,using in-situ hydraulic
conductivity data and topographic data gathered during the site testing and planning phase,prior to design
of the BMPs. Further,we propose that the inflow monitoring protocol be modified to reflect a more
accurate assessment of BMP function. Currently,inflow grab samples are collected within the pond
itself,allowing heavily diluted influent to be used as the inflow sample. Instead,we suggest that grab
samples be collected from each concentrated inflow point(pipe,flume, swale, etc.)for each respective
system and combined as a composite sample representative of each BMP system. We also request the
permit's monitoring requirements be modified such that it will be automatically eliminated if and when
the first four events sampled illustrate achievement of the design target of 90%TSS reduction. Lastly,we
ask that Mayfaire be allowed to perform the sampling more frequently than once per quarter to reach the
proposed minimum of four samples as quickly as possible,if weather patterns allow.
Proposed Howe Creek Monitoring Protocol:
• Total Suspended Solids shall be the only parameter sampled.
• Upstream and downstream samples shall be collected concurrent with the BMP outflow
sampling from wells.
• Monitoring requirements will be automatically eliminated when the BMP monitoring is
eliminated.
It is our opinion that Howe Creek should not be sampled during a representative storm event since flow
conditions during these potentially intense storms are not representative of normal aquatic conditions.
Rather,we propose that Howe Creek upstream and downstream samples be collected concurrent with the
BMP outflow sampling from wells installed as recommended above. Stormwater BMPs on this site are
designed to allow the untreated bypass of flows in response to storms more intense than the 1.5-inch
rainfall design storm;thereby allowing the possibility of sampling during one of these events that the
system was never designed or intended to treat. It is worthy to note that the site is very near full build-
out. Hence,we do expect average TSS values to continue to decrease over time as the site reaches full
build-out and we anticipate this will be illustrated over the next monitoring period if our proposed
protocol modifications are implemented.

storage of the design storm, which then directs that design storm runoff to an infiltration area and allows
excess design storm to overflow through a vegetated filter. The difference is that The Village uses pumps to
get from the pond to the infiltration area to the bypass and the Town Center uses gravity.
The quarterly sampling reports were reviewed by our ambient monitoring and NPDES staff people. As a result,
we are recommending quarterly sampling for at least 2 years.
1. Samples will be pulled for the first flush runoff into each wet pond storage area either at the last catch
basin, or the forebay, or at the end of the forcemain where it dumps into the infiltration basin (The
Village)—whichever is most convenient and accessible. This will allow us to know the quality of the

Sampling will be for TSS, hydrocarbons, nitrogen and phosphorous. This should be less costly to the permittee
than the current protocol. At the end of 2 years the permittee can again request to eliminate the sampling.
Depending on the results, the Division may or may not elect to eliminate.
A request to modify the permit to change the monitoring requirements will require a $505.00 fee and a new

Subject: RE: Mayfaire Sampling Changes Town Center&The Village
Georgette:
OK- I took notes from our discussion. I'll see if we can get with Linda W. and maybe Stephanie to make sure
they are OK with the changes to the sampling strategy. The 2 Mayfaire permits that are requesting elimination
of the monitoring are the Town Center and the Village at Mayfaire. We will not be eliminating the sampling, but
we will be modifying the sampling requirements in order to provide meaningful data.
Both projects have similar systems- pond storage areas that release slowly into infiltration areas with
overflows to vegetated filters. The main difference is that the Town Center uses gravity feed from the pond to
the infiltration areas and the Village uses pumps. I think we agreed that the simplified sampling protocols
should be the same though:
1. Inspection during a design storm event to make sure that no discharge to surface waters occurs. This is
the design basis of the system. Some of the systems were designed to handle 1.5", others were
designed to handle a larger design storm.
2. For storms exceeding the design storm, sample at the inlet to the storage area, at the bypass to the
vegetated filter, i.e., the point where the runoff in excess of the design storm enters the filter and at the
outlet of the vegetated filter before it gets into surface waters.
3. Fecal coliform sampling could be discontinued only if extra "pooper-scooper" stations are added around
the storage areas. The stations would have plastic bags and a disposal bin to encourage dog walkers
to pick up after their pets and dispose of the waste properly.

Thank you but no, there is no need for you to be there as we are meeting to discuss various other unrelated
permit matters as well. This is a big decision for the Division because of the manner in which the permits were
originally issued. It's important that we make the right decision for the right reason and that may take some
time. Please bear with us.
To my knowledge, we don't have a statutory time limit on this type of request, but if there is a time limit it will be
90 days, which is what is in the rules. We're currently well within the 90 days. I do expect to be able to provide

Sorry Tammy.This is on the back burner at the moment. When it's reviewed, I'll let you know.
A request to remove monitoring requirements from a permit has a lot of hoops to jump
II through. It will be going through many hands before anything is done.

Subject: WQ Sampling for Village at Mayfaire
Linda,
To follow up on our meeting last November 23rd, I have attached a summary of the pond inflow sampling results
I have on file.The 2Q07 and 3Q07 results are from MACTEC reports and the 4Q08 sampling was done by CCRG. I
am not sure this provides the consistent baseline data we expected. It does not surprise me as I would expect
significant fluctuations based on time of year, elapsed time after rainfall begins, intensity of rainfall,and time
since the last significant rainfall event.
At the November meeting,we agreed on a sampling program to include a minimum of 4 rainfall events of
sufficient intensity(minimum 1.5")to cause a discharge to the pond discharge vegetated filters.Samples would
be taken at the inflow and outflow points for Pond#1,#2,&#3 filters. I recommend we add an inflow sample at
each pond to be made at the same time as the filter samples.This would not provide first flush data but it would
provide a good snapshot of how each pond and filter performs at a given time in a given event.
We also discussed monthly inspections of the vegetated filters and infiltration basin.We are working with
Village at Mayfaire to upgrade the present maintenance and inspection program.
Please let me know how to proceed.We are ready to move forward with this work.

Mayfaire Town Center (Phase 1)
MONITORING DATA REVIEW/SUMMARY IN SUPPORT OF
REQUEST TO ELIMINATE INSTREAM AND BMP MONITORING
REQUIREMENTS
Dear Ms. Scott:
On June 03,2010,Total Stormwater Solutions,Inc.(TSS)submitted a request for the elimination of all
monitoring requirements for Mayfaire Town Center(Permit No. SW8 010512;renewal,dated January 18,
2008)on behalf of Mayfaire Management Company,LLC,(Mayfaire). In support of this request,Mr.Dan
Rahe(Mayfaire),Mrs.Tammy Spivey(TSS)and Mr. Scott Mitchell(TSS)met with Ms.Linda Lewis of your
office on June 07,2010,to discuss the request and potential concerns your office may have with the request.
During the meeting,Ms.Lewis explained that the purpose of the required monitoring was a means of
illustrating to your office,and concerned citizens and organizations,that the project was not degrading water
quality within Howe Creek. To-date,monitoring protocol has included quarterly storm event monitoring of
Howe Creek(upstream and downstream),Two Mile Branch, and inflow and outflow points of ponds 1,3
and 4. In addition,quarterly instream analytical monitoring of Howe Creek(upstream and downstream)and
Two Mile Branch has been performed during separate,non-storm event periods. Parameters tested on this
schedule included: 1)Total Suspended Solids,2)Turbidity,3)Dissolved Oxygen,4)Temperature,5)
Conductivity,6)Flow,and 7)pH. In addition to twice quarterly sampling for these parameters,fecal
coliform sampling has been completed for these same locations five times per month—a total of 60 times per
year per sample location. This level of sampling intensity has been sustained by Mayfaire since December
2004. During the June 07,2010 meeting,Ms.Lewis confirmed that Mayfaire was not required to sample the
BMPs that discharge into Two Mile Branch or Two Mile Branch itself;therefore,monitoring of Two Mile
Branch has been halted. In an email later that same day,Ms.Lewis confirmed that Mayfaire only needed to
pull 5 fecal samples in the month that the quarterly sampling was done—a total of 20 samples per year per
sample location.This change has also already been implemented by Mayfaire.
Mayfaire Town Centers' stormwater management system consists of two(2)alternative systems of wet
detention ponds and infiltration basins(systems#3 and#4),one(1)wet detention pond alone(system#1)and
one(1)infiltration basin alone(system#2). Per the approved permit,BMP monitoring requires grab samples
of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first
30 minutes of a discernible inflow from a representative storm event;the discharge outflow sample window
is within the first 30 minutes of discharge from that same storm event. BMP sampling locations were field
determined by DWQ staff in December 2004. Per DWQ's specifications on sampling locations,grab
samples have been collected within the ponds themselves,allowing heavily diluted influent to be used as the
inflow samples. Grab samples should be collected from each concentrated inflow point(pipe,flume,Swale,
etc.)for each respective system and combined as a composite sample representative of each BMP system. In
1

addition,the discharge outflow samples have been taken in locations that test water going to infiltration
basins,not water that may leave the basins and potentially impact Howe Creek before complete treatment;
outflow sample locations should be half-way between the basin and Howe Creek and be pulled
approximately 3-10 days after a representative storm event,allowing time for the entire BMP system to
perform its design function.
TSS has completed a thorough review of the monitoring data supplied to us by Mayfaire,which spans from
December 2004 to March 2010. We have compiled this data and attached the parameter summaries,
spreadsheets and graphs illustrating this data for your review.
In summary,all parameters tested for Howe Creek(except total suspended solids and turbidity),show slight
improvement or little to no change at the downstream sampling location in comparison to the upstream
sampling location. Even though turbidity samples show a slight degradation downstream, 76%of the
instream samples and 95%of the storm event samples meet the 15A NCAC 2B Standard of<25 NTU for SA
ORW waters.In addition,although the BMP outflow samples were taken at locations premature in the
treatment process,all parameters tested(except total suspended solids and turbidity),show slight
improvement or little to no change at the inflow sampling location in comparison to the outflow sampling
location. Overall,fecal coliform spikes are trending in the summer months when intense rainfall events are
typical,and pet walking around the BMPs,Howe Creek and upstream neighborhoods is greatest.
If DWQ is not willing to completely eliminate monitoring at this time,it is the opinion of Total Stormwater
Solutions that only the total suspended solids parameter needs continued monitoring to substantiate system
efficacy. If DWQ feels that additional monitoring is needed,Total Stormwater Solutions proposes the
following revised monitoring protocol,which more closely mirrors the design function of the BMPs,on
behalf of Mayfaire:
Proposed BMP Monitoring Protocol:
• Total Suspended Solids shall be the only parameter sampled.
• Three(3)monitoring wells shall be installed at each infiltration basin(Basins 2,3 and 4)
halfway between each infiltration basin and its receiving creek or stream.
• Grab samples shall be collected from each concentrated inflow point(pipe,flume,swale,etc.)
for each respective system and combined as a composite sample representative of each BMP
system.
• Samples from the monitoring wells shall be pulled approximately 3-10 days after a
representative storm event.
• Monitoring requirements will be automatically eliminated if and when the first four events
sampled illustrate achievement of the design target of 90% TSS reduction.
For BMP systems,we propose the monitoring protocol be modified to more accurately illustrate the efficacy
of each BMP. We propose that this be completed by installing 3 monitoring wells at each infiltration basin
(Basins 2, 3 and 4—Pond 1 discharges to Infiltration Basin 2;for a total of 9 wells)with wells located
approximately halfway between each infiltration basin and its receiving creek or stream. Samples for total
suspended solids shall be pulled approximately 3-10 days after a representative storm event,allowing time
for the entire BMP system to perform its design function. Actual lag time between inflow sampling and
outflow sampling from the proposed monitoring wells will be calculated more precisely upon your approval
of this revised monitoring protocol,using in-situ hydraulic conductivity data and topographic data gathered
during the site testing and planning phase,prior to design of the BMPs. Further,we propose that the inflow
monitoring protocol be modified to reflect a more accurate assessment of BMP function. Currently,inflow
grab samples are collected within the pond itself,allowing heavily diluted influent to be used as the inflow
sample. Instead,we suggest that grab samples be collected from each concentrated inflow point(pipe,flume,
swale, etc.)for each respective system and combined as a composite sample representative of each BMP
system. We also request the permit's monitoring requirements be modified such that it will be automatically
eliminated if and when the first four events sampled illustrate achievement of the design target of 90%TSS
2

reduction. Lastly,we ask that Mayfaire be allowed to perform the sampling more frequently than once per
quarter to reach the proposed minimum of four samples as quickly as possible,if weather patterns allow.
Proposed Howe Creek Monitoring Protocol:
• Total Suspended Solids shall be the only parameter sampled.
• Upstream and downstream samples shall be collected concurrent with the BMP outflow
sampling from wells.
• Monitoring requirements will be automatically eliminated when the BMP monitoring is
eliminated.
It is our opinion that Howe Creek should not be sampled during a representative storm event since flow
conditions during these potentially intense storms are not representative of normal aquatic conditions.
Rather,we propose that Howe Creek upstream and downstream samples be collected concurrent with the
BMP outflow sampling from wells installed as recommended above. Stormwater BMPs on this site are
designed to allow the untreated bypass of flows in response to storms more intense than the 1.5-inch rainfall
design storm;thereby allowing the possibility of sampling during one of these events that the system was
never designed or intended to treat. It is worthy to note that the site is very near full build-out. Hence,we do
expect average TSS values to continue to decrease over time as the site reaches full build-out and we
anticipate this will be illustrated over the next monitoring period if our proposed protocol modifications are
implemented.
Based on the fecal coliform spikes trending in the warmer summer months,presumably due to pet waste
(field verged)and intense,warm-weather rainfall events,Total Stormwater Solutions does not feel that
continued fecal coliform monitoring should be required,as BMPs are not designed or intended to reduce
fecal coliform concentrations. We do strongly recommend,however,that proactive steps be taken to address
the problem of pet waste deposition around BMPs and Howe Creek. To that end,Mayfaire has already
ordered pet waste removal stations to be installed at strategic locations throughout the property. Further,we
have also recommended the installation of public education signage regarding the impacts of pet waste on
surface water quality,providing residents and patrons with the knowledge required to actively take part in the
protection of Howe Creek.
Please do not hesitate to call or email us with any questions. Tammy can be reached at 910.622.7844 and
Scott can be reached at 919.669.0329. We thank you in advance for your time and for your consideration of
our requests.

Subject: Permit No.SW8 010512 Renewal
Mayfaire Town Center (Phase 1)
REQUEST to ELIMINATE INSTREAM and BMP MONITORING
REQUIREMENTS
Dear Ms. Scott:
On behalf of Mayfaire Management Company,LLC,Total Stormwater Solutions,Inc.(TSS)requests the
elimination of the monitoring requirements as outlined in Permit No. SW8 010512 Renewal, dated
January 18,2008.
Per section III, item 8 of the subject permit,the permittee may petition DWQ to have the monitoring
requirements modified,reduced, or eliminated after 10 valid data points have been submitted for each
BMP. Mayfaire Management Company,LLC has diligently had the required monitoring tests performed,
and provided the required quarterly reports to DWQ since December 2004. Total Stormwater Solutions
has compiled all of the data contained in these reports. Based on our analysis,the difference in the
upstream and downstream parameter data is not statistically significant(i.e.it varies greatly and shows no
obvious trend). As a result of the analysis, 5+years of data having been provided, the extreme costs
associated with continued tests and reporting,and the development having stormwater control measures
above and beyond normal,TSS respectfully requests that the Mayfaire Town Center monitoring
requirements be eliminated effective June 30,2010.
Please do not hesitate to call or email me with any questions. I can be reached at 910.622.7844. We are
looking forward to a productive meeting with Ms.Linda Lewis of your office on Monday,June 7 at
11:00.
Sincerely,
Tammy M. gPivey

Meeting Notes

Linda Lewis

Todd Edmiston, CAMS
Larry Sneeden
The meeting was requested by the permittee to revisit the sampling requirements. The
permittee contends that the sampling doesn't provide relevant data. The meeting was to
hash out a new sampling program such that it can provide sufficient results to DWQ to
allow the sampling to be discontinued.
Baseline information of the pond inflow constituents may be gleaned from the 2007 and
2008 quarterly sampling reports. Construction was nearing an end in the middle of 2007, so
the first and second quarter results may skew the data. The results will be submitted to
DWQ for approval. If DWQ feels that more data is needed, additional baseline inflow
sampling will need to be done.
No sampling of the inflow to the infiltration basin at the forcemain discharge points. This
runoff will be infiltrated, so knowing what's in it is probably pointless, since it is not being
discharged.
Inspections will be made monthly and during and after a design storm event to determine if
the system is handling the 1.5" event without discharging.
The outflow from a minimum of 4 events that exceed the 1.5" design storm and that
produce a discharge to the vegetated filters will need to be sampled during the upcoming
year in order to consider eliminating the sampling. As many events as possible should be
sampled. If less than 4 events are sampled in the upcoming year, DWQ will not consider
eliminating the sampling until more events are sampled. Pond #1 does not have a bypass
"pipe" to the vegetated filter from the outlet structure, where a sample can be pulled easily.
There is only a spillway. A
Upon approval of the baseline constituents in the inflow, the permit's monitoring will be
modified such that it will be up for elimination at the end of 1 year, with at least 4 events
sampled, no discharge of the 1.5" design storm, and a healthy reduction of pollutants from
inflow to overflow at the vegetated filter.
The sampling in the vegetated filter should take place at the beginning of the filter, not at
the end. If it's been dry, the pollutants in the filter may be resuspended in the runoff,
skewing the results. But, sampling at the beginning and at the end of the filter could be
beneficial to making the determination at the end of the year that the monitoring should be
eliminated.

Subject: Sampling Requirements
The Village at Mayfaire
Stormwater Project No. SW8 011119
New Hanover County
Dear Mr. Edmiston:
The Division received your request to eliminate the monitoring requirements from permit
SW8 011119 for The Village at Mayfaire. Your request brings up several valid points
however it appears that your request to eliminate monitoring is based on your belief that
it is not producing any relevant data. DWQ's current process for determining if a
monitoring requirement should be eliminated is based on the review of data submitted
by the permittee. Based on your review and analysis this data does not meet this
criterion. Therefore in order for us to make an informed decision about this monitoring
requirement, we need to discuss how to modify the sampling program for this site such
that more relevant data is gathered.
First, I propose that rather than sampling when it rains any amount less than the design
storm of 1.5", let's consider a thorough quarterly inspection of the system during and
after any design storm event, at the outlet/bypass structures, the forcemain outlets, the
infiltration system and the vegetated filters to see if the design storm is being picked up,
channeled, pumped and infiltrated without bypassing.
Second, I propose a more flexible number of sampling events, with 2 being the
minimum, and 4 being the maximum. This will take drier years into consideration, where
only 2 storms might produce enough runoff to be sampled, while still allowing for
sampling in each quarter during wetter years. Only larger storm events that are
expected to be in excess of the design storm, and that produce a discharge to the
vegetated filter, would be sampled.
Third, I propose to change the sampling locations in order to generate more relevant
data. Samples would be taken at the last catch basin leading into each pond, and at the
2 points where the forcemains from the ponds enter the spreader swale of the infiltration
basin during the first flush (1.5"). The larger storm event sampling would be subject to
the requirement for the preceding 3 days to be without rain. This will provide a good
basis for-the water quality entering the storage ponds and the infiltration basin.

Mr. Edmiston

Permit Number SW8 011119
Later in the storm, when the vegetated filters become engaged, samples would
be taken at each bypass structure overflow into the 3 vegetated filters at Ponds
1, 2 & 3. This will provide meaningful data on the water quality entering Howe
Creek from the excess design storm from this development. A comparison of the
pollutants in the runoff entering the infiltration basin vs. the pollutants in the
bypassed runoff would provide relevant data. If desired, two of the quarterly
inspections can be conducted concurrent with the semi-annual sampling events.
Perhaps we also need to address the timing of samples. As you have pointed
out, rain doesn't conveniently fall only between the hours of 8am and 5pm M-F
and labs are not necessarily open on the weekends or after business hours to
accept samples. I don't know how to address this as it is really a matter of
listening to the weather forecasts, planning ahead and being lucky in the timing
of the rain. A reduction to a minimum of 2 sampling events per year would
appear to help meet this requirement.
This would appear to be a more relaxed sampling program that would provide
more meaningful data without the onus of sampling on a quarterly basis when no
discharge is occurring. It seems that we've had several years with less than
normal rainfall amounts, with fewer target storms in that quarter to produce
runoff. I don't anticipate that will always be a concern, as there will most certainly
be wet years with more rainfall than average, where there will be multiple
opportunities for sampling. The reduction to a minimum of 2 sampling events per
year should accommodate the drier years.
Please call either Georgette Scott or me to set up a meeting to discuss these
proposed new monitoring requirements and offer any suggestions for
improvement. If you have any questions, please do not hesitate to contact me at
[phone] or email me at [e-mail].
Sincerely,

Wilmington, NC 28405
RE:Stormwater Sampling Requirements
The Village at Mayfaire
Stormwater Permit SW8 011119
Dear Ms Scott,
The stormwater permit for The Village at Mayfaire contains special stormwater monitoring
requirements for the discharge stream and BMPs. This letter is our petition to eliminate these
monitoring requirements as provided under Section III of the permit.
The stormwater management system consists of three wet detention ponds and an infiltration basin.
Stormwater is collected in the wet detention basins. The 2-5 day drawdown of the design storm in the
ponds is accomplished by pumping the drawdown water from an intake in the pond outlet structures to
the infiltration basin. For storm events greater than the 1.5" design storm the overflow from the wet
detention basins flows through vegetated filters before off-site discharge. There is no overflow of the
infiltration basin as it receives only the design storm drawdown flow, not direct runoff. A small holding
pond collects runoff from the entrance road for pumping to a wet detention basin.
The monitoring requirements are for quarterly in-stream sampling during rain events upstream and
downstream of the project, and concurrent sampling of the inflow and discharge of the BMPs (wet
detention ponds). The inflow samples are taken during the first 30 minutes of discernible inflow from a
representative storm event (>0.1 inches of rain), and the outflow samples are to be taken in the first 30
minutes of discharge as a result of that event. Sample locations were determined in conjunction with
NCDENR.
The permit provides specific conditions for the modification, reduction, or elimination of the monitoring
requirements. This request does not fully address those conditions. We believe our request for
elimination is justified for the following reasons:
In-stream Monitoring:The in-stream sampling locations are located about 300 feet apart on the
creek. In the 300 feet between samples, there are no point source discharges from the project
for the design storm and only very minor discharges from impervious surfaces (sidewalks). This
stream does not respond immediately to a rainfall event and is typically at zero flow (stagnant)
during a small but representative storm event.With the very limited flow and no discharge from
the project, the two samples measure the quality of standing water in the stream rather than
any impacts on water quality. The only project flow into the stream would occur for events
greater than the 1.5" design storm, and that flow would occur more than 30 minutes after the
start of discernible flow and would therefore not be sampled. As a result of the foregoing

HE } '
VILLAGE
M I VFA1RE
sequence of events, in-stream monitoring provides no relevant data regarding functioning of the
project stormwater management system or impacts on the creek.
BMP Monitoring:The sampling points for the BMP's are located at the inflow pipe and discharge
structure of each wet detention pond. Several factors about these specific ponds should be
considered. Due to the sandy soils, each of three ponds typically draws down below the normal
pool elevation between rain events. The ponds do not begin to discharge (to the infiltration
basin) until the water level rises above the normal pool elevation, which may require a
substantial rainfall event. The ponds may begin at different levels, so two ponds may discharge
during an event and the third may not. The discharge samples provide data for water going to
an infiltration basin, not water that will leave the site and potentially impact downstream
waters.The BMP monitoring provides no relevant data regarding impacts on surface waters.
Representative Rainfall Events:The representative rainfall event must be a greater than 0.1 inch
rainfall preceded by three days with no rain. That is a simple and straightforward requirement
on paper. In practice, it is difficult to anticipate and prepare for a rainfall event that will follow
three days of no rain, will rain enough to fill up each pond to at least normal pool level and
create a discharge, will rain enough to create flow in the creek, and begin and end in time so
that the samples can be delivered to the lab within six hours and by 5:00 on the same day.
Our project wet detention ponds are maintained on a regular basis and monitored for compliance with
the stormwater permit. The system functions as designed and permitted with no discharge to surface
waters during a design storm event. The monitoring program, while well intentioned, does not provide
relevant data does not add environmental protection and does not measure any impacts. We request
you eliminate these requirements from the permit.
We appreciate your consideration of this issue. If you have any questions or concerns, please contact
Mr. Larry Sneeden at 910-520-1835.

Linda,
On behalf of the Village of Mayfaire(VOM),we are submitting this plan of action for monitoring
compliance stipulated in the project permit and your letter of May 13th. VOM has retained our
services to provide the required monitoring and sampling and we are moving forward as quickly as
possible. We ordered the necessary sampling meter and expect delivery within 3 weeks. Upon receipt,
we will proceed immediately with both the dry weather sampling and rainfall event sampling as
weather permits. I expect to complete the quarterly sampling by the end of August, receive lab results
by mid-September, and submit a report to you by the end of September for the 3rd quarter. We will
make every effort to expedite this process, but the above represents a reasonable schedule for
completion.
Prior to taking the first samples, I would like to meet at the site with you and/or Stephanie Garrett to
verify the approved sample locations, discuss a split sampling event, and review any other issues with
the permit and sampling. Shall I contact you or Stephanie to set that up?
Please let me know if you require any additional information at this time.

. Subject: NOTICE OF VIOLATION
The Village at Mayfaire
Stormwater Permit No. SW8 011119
New Hanover County
Dear Ms. Riffle:
On March 7, 2008, Wilmington Regional Office personnel performed a split sampling event
with MACTEC Engineering personnel, as required by each of the 3 main permits issued for
Mayfaire. The original permit for The Village at Mayfaire, SW8 011119, was transferred to the
Association on December 7, 2007. The project is located on Town Centre Drive in Wilmington.
New Hanover County, North Carolina.
The project has been found in violation of Stormwater Permit Number SW8 011119 , issued
pursuant to the requirements of 15A NCAC 2H.1000. The violations found are:
1. Section 111.1 thru 111.10- The permit requires quarterly monitoring and sampling of
specific rain events throughout the year. Since the permit has been transferred,
the Division has not received a quarterly monitoring report. As the permittee of
record, the Association is responsible for collecting the water samples, analyzing
them, and reporting the results to the Division.
To correct this violation you must:
1. Provide a written "Plan of Action" which outlines the actions you will take to
correct the violation and a time frame for completion of those actions, on or
before June 13, 2008.
2. Make arrangements to have the quarterly sampling done, generate a report of
the results, and submit that report to the Division.
Failure to provide the "Plan of Action" by June 13, 2008, or to correct the violations by the date
designated in the "Plan of Action", are considered violations of 15A NCAC 2H.1000, and may
result in the initiation of enforcement action which may include recommendations for the
assessment of civil penalties, pursuant to NCGS 143-215.6A.
By copy of this letter to the New Hanover County Building Inspector, this Office is requesting
that the Building Inspector consider withholding building permits and Certificates of Occupancy
for this project until this matter is satisfactorily resolved.
