City of Henderson Oper ervice Center
Dear Ms. Alexander:
r
22
Please find enclosed the following monitoring reports with respect to our stormwater discharges at 900
Beckford Drive, Henderson NC. The City was required to perform semi-annual Stormwater Discharge
Monitoring at three outfalls that discharge into the riparian buffer and ultimately discharge into Nutbush
Creek in the Roanoke River Basin.
The City of Henderson has a Standard Industrial Classification 40 that includes activities associated with
Vehicle Maintenance Areas. The city has a Stormwater Pollution and Prevention Plan and is required to
monitor pH (6-9), non -polar grease (EPA method 1664) (<l 51-ng/1), Total Suspended Solids (<100 mg/1),
Total Rainfall and New Motor Oil Usage (gal/month).
Over the course of our monitoring, the wastewater department stopped collecting the stormwater samples
and the engineering department was put in charge of the sample collection. The wastewater department
stopped collecting the sample because the sampling protocol required them to come to our site within 20
minutes of the start of a rain event and in many cases outfall SDO-002 required them to stay on site for
hours during a light rainfall event to collect a sample due to its small drainage area.
Due to the constraints of the permit relative to the first flush, it became evident that staff was not always
present to collect the sample during a rain fall event so, the engineering department utilized a stream
sample bottle to collect the stormwater sample. The City went through at least 5 iterations of how to
install the sample bottles for an unmanned collection. In all cases the stream sample bottle had to be
buried below grade so the first flush would run across the depression and drop into the sample bottle (see
attached drawing). We went through many arrangements of setting up the sample bottles collection
system by digging in front of the RCP outlet but we got varied responses to the stormwater quality and it
eventually forced us to move towards a tier 2 (monthly) sampling protocol (TSS has been a parameter that
exceeded permit limits at various times).
The City hired a consulting engineer/firm to install stormwater devices to improve the water quality and
revise the stormwater collection system. These devices significantly helped the water quality but, we
were still collecting samples by burial of a sample bottle in a sample collection tube. Both before and
after the installation of the engineered system we had to set stones on top of the collection tubes because
the collection tubes kept floating out of the hole. It is my firm belief that in many instances the sample
was contaminated due to turbidity in the pit, not the stormwater itself. I have not figured out how to get a
quality un-manned sample and would like to have a detailed discussion with you to help the city rectify
this problem.
The current engineered system is believed to be functioning correctly but SDO-003 maybe experiencing
rising TSS levels due to the reduced assimilative capacity of the engineered system. Public Works is
scheduled to clean these devices within 2 weeks of this letter. Please note that SDO-003 is the largest
drainage area and drains the bulk material storage (aggregates and soil) area which is leading to a blinding
of the City's engineered system. Please see the attached devices that proved very effective until the
devices began experiencing break through with respect to TSS. No gas, oil, unusual water color or odors
were ever reported on any of the outfalls' discharge location before or after the engineered system
installation.
Attached are the results of our monitoring both before and after the engineered devices.
I have included the following for your review:
1. Semi-annual Stormwater Discharge Monitoring Report summary sheet
2. 1 sketch of the Operations Center and discharge points.
3. A sketch of the non -manned sample collection device set-up.
4. Layout of the engineered system.
I spoke with DEQ on two occasions to let them know some of the problems we were experiencing and
some of the measures we took to mitigate these issues. Two consecutive samples exceeded the same
benchmark (TSS) and we self-imposed a Tier 2 monitoring level. Henderson took the following
corrective actions at the facility to resolve the TSS issue.
l . The parking area was swept
2. The storm sewers were jetted clean to remove any deposition that may have occurred in the
lines and that would potentially migrate to the discharge point at the first flush.
3. Silt bags were installed in the drop inlets at the back of the facility as secondary containment.
4. Mulch logs will be installed in front of the material storage bins as primary containment.
Henderson has a full service garage, fuel depot and utility operations/equipment at this location. The
utility operations performed from this location includes repair and maintenance of the following
infrastructure; water distribution, sewer collection, stor nwater and streets. The following materials are
stored in sheds on site; sand, salt, #67 stone, aggregate base course, screenings and mulch. These
materials are used in our daily operations but, the storage sheds are open on one side to permit loading
and unloading of dump trucks but, this open side during a driving rain exposes the material to the
elements and there is positive drainage away from the building. Most of this material stays put in these
bins but, during an emergency repair this material is removed from the bins and loaded on trucks where
some of the material can potentially be spilled on the asphalt adjacent to the storm drain. When water and
sewer lines break the crews address the immediate environmental or property threat associated with the
utility line break and then address cleaning the spilled materials as part of a house keeping measure.
Therefore silt socks were installed in the drop inlets as a secondary containment and mulch logs will be
installed in January as part of the primary containment. We will also increase our house keeping of this
material with power brooms to keep the material from entering the storm drain.
The City of Henderson has taken proactive measures to bring the discharges back into compliance. The
City will perform maintenance on the engineered systems and continue monthly monitoring but we do
request technical assistance on how to collect unmanned samples without exceeding the TSS.
If you need anything else please do not hesitate to contact me.
Sincerely,
&uk ?

All permits require qualitative monitoring to be performed during a "measurable storm event."
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DEMLR Regional Office.

See the below. I estimated the city of henderson scope which i bet you guys might be able to
improve upon. Our approach includes installing a 40' level spreader geotextile tube with two 25'
returns.
The fabric material is UV stabilized for 30 years in coastal conditions so i expect it to outlast you
and 1. Some maintenance will be required to clean out from time to time especially as the
vegetation establishes. I like to use young plants and manage them as they establish. The
below scope should address DEQ/DENRs issues as i have seen Level Spreaders applied for
metal recycling and shredding facilities that have far more hazardous outfall conc. than what i
expect you guys have. I'd be happy to catch up to go over the below when you have a second.
Here is the proposal/estimate/quote for what we propose to address the NPDES issues at your
site:

Re: Semi -Annual Report — December 2014
General Permit #NCG080000
Certificate of Coverage NCGO80713
City of Henderson Operations and Service Center
Dear Mr. Randall:
DEC 8 0 2014
C8NTIZgL Fl
DWR SECTION
Please find enclosed the following monitoring reports with respect to our stormwater discharges at 900
Beckford Drive, Henderson NC.
1. 1 originals of the semi-annual Stormwater Discharge Monitoring Report (Date 1 1/6/2014)
2. 1 original of the SDO Qualitative Monitoring Report for each of the three discharge points.
(Date 1 1 /6/2014)
3. 1 sketch of the Operations Center and discharge points.
This facility failed to meet ONE of the THREE benchmarks required in the General Permit. The
elevated value was total suspended solids (TSS) as sampled on November 6, 2014 at both SDO # 1 and
SDO #3 with respective sample values of 176mg/l and 164mg/l.
The facility exceeded the benchmark for total suspended solids (TSS) on the previous semi-annual
Stormwater DMR at SDO #3. The previous sample was taken on May 14, 2014 with a TSS value of
162mg/l. Due to two consequetive samples having exceeded the same benchmark our monitoring status
has moved to Tier 2 level. Henderson took the following corrective actions at the facility to resolve the
TSS issue.
1. The parking area was swept
2. The storm sewers were jetted clean to remove any deposition that may have occurred in the
lines and that would potentially migrate to the discharge point at the first flush.
3. Silt bags were installed in the drop inlets at the back of the facility as secondary containment.
4. Mulch logs will be installed in front of the material storage bins as primary containment.
Henderson has a full service garage and utility operations center for water, sewer and storm at this
location. The following materials are stored in sheds on site; sand, salt, #67 stone, aggregate base course,
screenings and mulch. These materials are used in our daily operations but, the storage sheds are open on
one side to the elements and have positive drainage away from the building. Most of this material stays
put in these bins but, during an emergency repair this material is removed from the bins and loaded on
trucks where some of the material can potentially be spilled adjacent to storm drain. When water and
sewer lines break the crews address the immediate environmental or property threat associated with the
,utility and then address cleaning the spilled materials as part of a house keeping measure. Therefore silt
socks were installed in the drop inlets as a secondary containment and mulch logs will be installed in
January as part of the primary containment. We will also increase our house keeping to this material
swept up and from entering the storm drain.
Pldase understand that Henderson is taking proactive measures to work back into compliance and we will
report our status and progress in the forthcoming months.
If you need anything else please do not hesitate to contact me,
Sincerely,
94 ;- J
