Correction to COC
Meadowview Road County Landfill
COC Number NCG120023
Onslow County
We were alerted that the receiving water shown on your Certificate of Coverage (COC) was incorrect. We have
revised our permit files and records to reflect the correction, and we are sending you a revised COC. The COC
now notes the receiving waters as "Southwest Creek, a class C;NSW stream, in the White Oak River Basin."
Previously the COC showed Blue Creek as the receiving water —a mistake carried over from when the permit
was originally issued.
On August 41h, Mr. Daniel Forbes submitted a request on your behalf to add a new stormwater discharge outfall
location for the new vehicle maintenance facility (VMF) being constructed later this year. Because the VMF is
part of the landfill site covered under your current NPDES discharge permit, there is no need to modify your
permit. Please revise all appropriate Stormwater Pollution Prevention Plan documents, site plans, secondary
containment records, and monitoring protocols to include discharges from the new stormwater outfall
associated with this facility, and abide by all other applicable permit conditions in General Permit NCG120000.
The effective date of renewed permit coverage (December 12, 2012) remains the same; however, this COC
reflects the date of the correction. Please replace the COC with the attached document. If you have any
questions regarding this correction, please contact me at [phone].

Blue Creek is not correct. The attached map shows Blue Creek south of the landfill parcel. The COC should be corrected
to show Southwest Creek. Outfalls 1 and 2 discharge to an unnamed tributary of Southwest Creek. Outfall 3 discharges
to a former borrow pit and that discharge never leaves the site. You can see this borrow pit immediately adjacent to
Outfall 3 in Figure 1 provided with the letter I sent. Stormwater from the VMF will be collected in the perimeter drainage

Hi Dan,

I pulled the permit file for this one, and I noticed that the Certificate of Coverage does not include Southwest Creek. It
lists Blue Creek (Class SC; NSW). Attached is the electronic copy of the renewal COC.
Is that correct? I can't tell for certain from the aerial, but I think you said the new VMF outfall would ultimately
discharge to the same waters as the other three active outfalls do today. Does Southwest Creek need to be added to
the COC, or does the COC need to be corrected because Blue Creek is not correct? It might be that the wrong stream is
affiliated with this permit in our database.

Subject: Stormwater Monitoring for New Vehicle Maintenance Facility
Onslow County Solid Waste Facility
Dear Ms. Georgoulias:
CDM Smith Inc. (CDM Smith), on behalf of Onslow County (County), is submitting this request to add a
stormwater outfall monitoring location for the new vehicle maintenance facility (VMF) under the
existing National Pollutant Discharge Elimination System (NPDES)'General Permit (Certificate of
Coverage Number: NCG120023) for the Subtitle D Landfill. The General Permit was issued on November
1, 2012, and will expire on October 31, 2017. A background summary of the existing NPDES monitoring
program, VMF outfall details, and an estimated monitoring schedule are detailed below.
Background
The Onslow County Solid Waste Facility consists of two closed unlined landfills (Permit Number 67-05),
an active Subtitle D landfill (Permit Number 67-09), a materials recycling facility operated by a private
company, and administrative and vehicle/equipment maintenance buildings. Stormwater runoff from
the Subtitle D landfill is captured in a perimeter drainage ditch and channeled to three sedimentation
basins located around the landfill. The runoff is eventually discharged through outfalls (Outfalis 1
through -3) located at each sedimentation basin. Stormwater samples are collected semi-annually from
the outfalls and analyzed for chemical oxygen demand, fecal coliform, and total suspended solids in
accordance with the General Permit. A site map showing the outfall locations is provided on Figure 1.
A compliance inspection was conducted by the Division of Water Quality (DWQ) on January 23, 2013, to
evaluate the County's request to remove Outfall 1 from the monitoring program and to ensure
compliance with their NPDES permit. Outfall 1 discharges stormwater runoff from the partially closed
portion of the Subtitle D landfill. The partial closure, from bottom to top, consists of a minimum 12-inch
thick intermediate soil cover layer (also serving as the cap liner system subgrade), gas venting
geocomposite drainage net (CDN), textured 40-mil linear low density polyethylene geomembrane,
stormwater management CDN, a minimum 18-inch thick protective soil cover layer, and a minimum
6-inch vegetative soil cover layer to promote grass growth and help stabilize slopes. Based on the
co
WATER + ENVIRONMENT +TRANSPORTATION + ENERGY + FACILITIES

Ms. Bethany Georgoulias

inspection results, the County was found to be in compliance with their NPDES permit and granted
representative outfall status for Outfall 1, which eliminated collecting stormwater samples
semi-annually at this location. Qualitative monitoring continues to be performed for Outfall 1 in
accordance with the permit conditions.
Samples collected from Outfall 3 during the 2014 semi-annual sampling events had detections of fecal
coliform and chemical oxygen demand above their respective benchmark value. These benchmark
exceedances were related to washouts on the east side slope of the active portion of the Subtitle D
landfill. In response to the benchmark value exceedances, the County implemented Tier One and Two
responses. The County has been performing Tier Two monitoring (monthly) for Outfall 3 since January
2015 and will continue until three consecutive sampling events are below the benchmark values.
Vehicle Maintenance Facility Outfall
The County is preparing to construct a new VMF that will service County and landfill vehicles and
equipment. The VMF will include a new access road and parking area as shown on Figure 2. Stormwater
runoff from the new VMF will be monitored at Outfall VMF as shown on Figure 1 in accordance with the
General Permit. Stormwater samples will be collected semi-annually from the outfall and analyzed for
non -polar oil & grease using U.S. Environmental Protection Agency Method 1664 and total suspended
solids using Standard Method 2540D. All samples will be analyzed by a North Carolina certified
laboratory. Stormwater pH will be measured during each sampling event. Sampling results, including
total precipitation as measured from an on -site rain gauge and an estimate of the volume of new motor
and hydraulic oil on -site for each sampling event, will be maintained with the operating records for the
landfill. Qualitative monitoring results will also be maintained.
Stormwater runoff from the new VMF will be collected in a drainage channel located around the
perimeter of the south closed unlined landfill as shown on Figure 3. Stormwater in the drainage channel
flows to a former borrow pit.(D_ischarge from the.former borrow pit is to an unnamed-tributary_ofi
CSouthwest Creek. Southwest,Creek is approximatelyr5;100_feet west of'the western property boundary.
Monitoring Schedule
Construction activities for the new VMF are estimated to begin in the fall or winter of 2015 and will
likely be completed in the spring or summer of 2016. Preliminary grading activities and the installation
of erosion and sedimentation control measures began in July 2015. Semi-annual sampling activities -will
begin when there is more than 55 gallons of new motor or hydraulic oil on -site when averaged over the
calendar year (660 gallons).
Stormwater monitoring for the existing VMF is not performed because the volume of new motor or
hydraulic oil that is used does not average more than 55 gallons a month over the calendar year. The
County anticipates using the existing VMF for new motor and hydraulic oil storage in the fall of 2015.

To: Willis, Linda
Subject: 'RE: Onslow County Landfill - NPDES Monitoring Program Modification Request
Hi Linda,
Thanks for copying me. Per our discussions earlier, I think we are in the right place here with your
directions to the consultant and the County. Onslow County is requesting removal of Outfall No. 1 from
coverage under their COC, NCG120023. If you or I get any further contact on this point, I think I'd like to
clarify my thinking in preparation for that contact. Just so we are prepared. From a permitting
standpoint, I'd clarify my perspective on the several issues raised by the consultant as follows:
1. Beginning point: Federal NPDES regs require a permit for stormwater discharges from industrial
activity areas at landfills. Onslow County holds our NCG120 permit, and is obligated to monitor the
outfalls, and comply with the Tier and benchmark provisions. Onslow has asked DWQ for a
relaxation of monitoring obligations.
2. Within our General Permit NCG120 there are some provisions that allow relaxed monitoring
obligations:
a. We can „grant representative outfall status if we concur that it is appropriate. Onslow
County has not requested representative outfall status in this letter.
b. We can grant relief from monthly monitoring under Tier 2 if we think continued
monitoring is not helping solve a mystery, or if continued monitoring is not moving the
permittee closer to a solution for reducing polluted discharges. Onslow County is requesting
we relieve them of monthly, and really all, sampling from Outfall 1. My perspective:
Onslow County has not done enough monitoring to solve a mystery, or to prompt them to
attempt to address the fecal discharges. The data set accumulated is small, and the
reporting of the test results is flawed (i.e., `greater than'). The consultant has just jumped
to the cause he thinks is likely, and the solution that he thinks avoids further costs: wildlife
is the cause, and his low cost solution is do nothing and stop tesj . He has asserted these
conclusions, but he has not presented.a persuasive case for these conclusions.
c. And we can eliminate the regulation of portions of landfills that are closed under
past policy of our program, under which we interpret that those closed portions of landfills
are no longer engaged in active industrial activity, and so are not under NPDES regulations
for stormwater permitting, and so are not subject to the provisions of the NCG120.
Although the argument presented by the consultant is not sharply focused, this is his best
point. But, it's not quite a strong enough point.
i. Looking at the cap system described in the letter for the Partially Closed portion:
it's 36" of soil in three layers with the top vegetated, a gas vent system, and a
shallow infiltration collection and discharge system. This is a very good (and I
presume a FINAL) cover, ie the one that DWM will require over the whole site,
eventually. So, under our implementation of the federal NPDES rules, we really
could consider that portion of the landfill as closed, and its discharges as no longer
regulated.
ii. Except that these flows from the very good Partially Closed portion commingle
with the flows from the TemRorarily Closed portion, and the engineer provides
no description of the closure for the Temporarily Closed portion. Instead, he reports
that that portion is slated for future expansion. It discharges to Outfall No. 1.
Outfall No. 1 therefore is receiving flow from a portion of the facility that has not yet
received final closure. And so the discharges from Outfall No. 1 are still regulated.
iii. So, in conclusion on this point it seems to me that the argument is not quite
strong enough for us to exclude Outfall No. 1 from regulation under the permit. But
thinking a little further on this, if the permittee were to re -grade the Temporarily

Closed portion (the central plateau of the fill) and direct runoff from that portion to
Outfalls No. 2 or 3, leaving Outfall No. 1 to receive flow from the truly closed portion,
I think that would allow us to grant their request to stop sampling Outfall No. I. in
some form. But, they have not proposed that, yet.
3. The consultant has also thrown in the argument of'wildlife.' Essentially, he offers the argument
that because the fecal coliform is from wildlife, fecal measurements should not be considered
exceedances, and by extension should not be compared to benchmark values, and should not
trigger the Tiered structure as a management response to polluted discharges.
a. The consultant has made no report that the permittee has attempted g-ay remedial
measures, even on the cheapest, smallest scale; he's just asking to be excused;
b. The consultant has not offered anything other than conjecture as to the source of the fecal
concentrations being wildlife;
c. And even if he did substantiate that wildlife contributes most or all of the polluted
discharges, DWQ is not yet persuaded that landfills in general should be excused from the
potential surface water impacts of fecal contributions of wildlife at' landfill sites:
i. Consider that if the permittee was not operating a landfill, that concentration of
wildlife would not occur, and would not result in high fecal content in the stormwater
runoff. So, the presence and operation of the landfill is the roximate cause of the
fecal pollution, whatever its source;
ii. And further, consider that our brothers and sisters in DWM require the control of
vectors as a legitimate area of regulation and permit conditions, Even though the
landfill operators might raise the same issue that those vectors are "wildlife', are just
natural, and consequently the permittee should not be obligated to try to control
something clearly_ outside_ of their control. But, that doesn't happen, does it? No,
the permittees understand their obligation to control vectors under the DWM permit.
Consider that DWM requires control of vectors for exactly the same core reason that
our permit measures fecal coliform content: reduction in the risk of bacteriological
pollution. DWM's focus is on human health consequences from that pollution, while
DWQ's focus is on the aquatic environment consequences.
Linda, I think your direction to the consultant and permittee are right on the mark: they need to put
together a better case for any request; they need to step through the structure of the permit (Tier 2, Tier
3) first as laid out in the permit text; and they need to at least make some attempt to respond to the
exceedances other than an immediate request to be excused. Ultimately, it's very possible we will excuse
them: other Regional Offices have, and the Central Office SPU is fully on board with that. But only upon
some more evidence of trying to understand and solve the problem, not just asking to be excused.

Daniel,
I reviewed the monitoring data. Thanks much for sending that for our review. The data
collected in 2012 is showing an elevation of fecal concentration relative to 2010 and 2011.
The concentrations reported as greater than is a problem since the values could be anything
above the concentration reported (>2,420 on 10/2/2012). Without the proper dilutions being
made to provide accurate analyses, we have no choice at this juncture than to ask that the
County continue monitoring outfall #1. The County should instruct the laboratory to conduct
the appropriate dilutions in,order to obtain more accurate readings. DWQ cannot make a
decision based upon "greater than" values, since the actual concentrations could be
problematic for surface waters. We must have more accurate data from which to make a
decision, especially concerning the abandonment of monitoring at an outfall that is showing
an upward trend for bacteria concentrations. It is certainly possible wildlife is
influencing the bacteria data. The County will need to institute Tier 2 responses including
monthly monitoring. This is consistent with the permit. We'd like to see more data before
making a decision to eliminate an entire outfall. After we have some data to review, we can
discuss decreasing the monitoring back to semi annual monitoring. We can alleviate the
requirement for monthly monitoring even though continued exceedances occur, but we need to
pretty certain about the sources (wildlife vs pollutants associated with the landfill) and/or
the permittees intentions to resolve the issues. I will contact the county and relay this
information to them and ask them to be sure they instruct their laboratory to conduct the
appropriate dilutions when analyzing Fecal Coliform.
Best Regards,
Linda

Program Modification Request
Attached is a request letter for removing Outfall No. 1 from Onslow County's NPDES monitoring
program. Fecal coliform has been detected in consecutive sampling events at Outfall No. 1
above the benchmark value. The fecal coliform detections are likely wildlife related as
stormwater runoff discharged through Outfall No. 1 is from partially closed areas of the
landfill that are constructed with a liner system. The liner system prevents leachate from
being discharged. Additionally, no other pollution sources are known. Based on a preliminary

RE: Onslow County Landfill - NPDES Monitoring Program Modification Request
Daniel,
I reviewed the monitoring data. Thanks much for sending that for our review. The data
collected in 2012 is showin� an elevation of fecal concentration relative to 2010 and 2011.
The concentrations reported'as greater than is a problem since the values could be anything
above the concentration reported (>2,420 on 10/2/2012). Without the proper dilutions being
made to provide accurate analyses, we have no choice at this juncture than to ask that the
County continue monitoring outfall #1. The County should instruct the laboratory to conduct
the appropriate dilutions in order to obtain more accurate readings. DWQ cannot make a
decision based upon "greater than" values, since the actual concentrations could be
problematic for surface waters. We must have more accurate data from which to make a
decision, especially concerning the abandonment of monitoring at an outfall that is showing
an upward trend for bacteria concentrations. It is certainly possible wildlife is
influencing the bacteria data. The County will need to institute Tier 2 responses including
monthly monitoring. This is consistent with the permit. We'd like to see more data before
making a decision to eliminate an entire outfall. After we have some data to review, we can
discuss decreasing the monitoring back to semi annual monitoring. We can alleviate the
requirement for monthly monitoring even though continued exceedances occur, but we need to
pretty certain about the sources (wildlife vs pollutants associated with the landfill) and/or
the permittees intentions to resolve the issues. I will contact the county and relay this
information to them and ask them to be sure they instruct their laboratory to conduct the
appropriate dilutions when analyzing Fecal Coliform.
Best Regards,
Linda

Linda, /
Attached is a request letter for removing Outfall No. 1 from Onslow County's NPDES monitoring
program. Fecal coliform has been detected in consecutive sampling events at Outfall No. 1
above the benchmark value. The fecal coliform detections are likely wildlife related as
stormwater runoff discharged through Outfall No. 1 is from partially closed areas of the.
landfill that are constructed with a liner system. The liner system prevents leachate from
being discharged. Additionally, no other pollution sources are known. Based on a preliminary
discussion with Ken, discharge from Outfall No. 1 may not be a regulated discharge.
Additional details are provided in the letter.

Please let me know if you would like to schedule a site visit prior to making a
determination. I have a full schedule next week but could meet you at the landfall any day
after. Please let me know if you have any questions or need additional information.

Subject: Outfall Removal Request
Onslow County Solid Waste Facility — NPDES Monitoring Program
Certificate of Coverage Number - NCG120023
Dear Ms. Willis:
amp Dresser McKee & Smith (CDM Smith), on behalf of Onslow County (County), is submitting this
request to remove Outfall No. Ifrom the national Pollutant Discharge Elimination.System (NPDES)
monitoring progr am. fhe request to remove Outfall No. 1 is based on a preliminary discussion with
Mr. Ken Pickle with the North Carolina Department of Environment and Natural Resources - Division
of Water Quality (DWQ) on October 31, 2012 that the discharge from Outfall No. 1 may not be a
regulated discharge. Background information about the monitoring program, details of the Subtitle D
landfill partial closure and conclusions for removing Outfall No 1 from the program are provided
below.
Background
The Onslow County Solid Waste Facility consists oiCtwo closed unlined landfills an active�ubtitle D
landfill)and a%naterials recycling facility)that is operated by a private company. The NPDES program
for the facility monitors stormwater runoff fro ,the active Subtitle D landfill. Stormwater runoff is
captured in a perimeter d ra inage ditch and channeled to three sedimentation basins located around
the perimeter of the landfill. The runoff is eventually discharged through outfalls located at each
sedimentation basin. The locations of Outfall No. 1, -2, and -3 and the sedimentation basins are
provided on Figure 1.
Samples collected from Outfall No. 1 during the precipitation event on October 2, 2012 had detections
of fecal coliform (greater than 2,420 colonies) above the benchmark value. This was the second
consecutive detection above the benchmark value, which requires the County to perform the Tier 2
response and repeat the required actions for the Tier 1 response.[e County is waiting for a

determination from the DWQ or removing Outfall No. 1 from the monitoring program prior to
implementing the Tier 2 response Note that a Tier 1 response was filed at the facility after fecal
coliform was detected (greater than 2,420 colonies) above the benchmark value in samples collected
from Outfall No. 1 during the previous monitoring period (i.e. January 1 —June 30, 2012).
Partial Closure
Phase I of the Subtitle D Landfill Partial Closure Construction Project was completed in December
2010 and resulted in the closure of approximately 13 acres on the south and west slopes. Temporary
closure of the east slope and plateau was also completed. The partially closed areas were capped with
a liner system and the temporarily closed areas were not due to future landfill expansions. The partial
and temporary closed areas of the landfill are provided on Figure 1.
The final cover for the partial closure, from bottom to top, consists of a minimum 12-inch thick
intermediate soil cover layer (also serving as the cap liner system subgrade), gas venting
geocomposite drainage net (CDN), textured 40-mil linear low density polyethylene (LDP)
geomembrane, stormwater management CDN, a minimum 18-inch thick protective soil cover layer,
and a minimum 6-inch vegetative soil cover layer to promote grass growth and to stabilize the slopes.
The Phase 1 Partial Closure Construction Project also included the installation of a landfill gas (LFG)
venting system. The gas venting system consists of the gas venting CDN, vertical LFG wells, and
surface collection piping.
Stormwater runoff in the partially and temporarily closed areas of the landfill is controlled by drainage
berms and channels that direct runoff to concrete open throat yard inlets. The yard inlets are
connected to 18-inch diameter corrugated high -density polyethylene downdrains that discharge the
runoff to the perimeter drainage channel. The plateau is graded to channel runoff to a downdrain
located on the west side of the landfill. The downdrain locations are provided on Figure 2 and the
drainage berms can be seen in the aerial photo. Precipitation that infiltrates through the protective
cover to the stormwater CDN installed in the partially closed areas of the landfill is directed to LDP
drainage flaps that discharge stormwater to the drainage channels.
Conclusions
Sedimentation Basin 1 collects stormwater runoff from the partially closed areas of the Subtitle D
landfill and the temporarily closed plateau that is discharged through Outfall No. 1. The drainage area
for Sedimentation Basin 1 and flow direction for the perimeter drainage channel is provided on Figure
qas venik 2. The liner system installed for the partial closure eliminates the potential for leachate to be collected
J in stormwater runoff that could be discharged though Outfall No. 1.

The fecal coliform benchmark exceedances in Outfall No. lure likely wwildlife.rel'ated.and not from Qe{- a410
leachate. The landfill is known to be used by numerous migratory birds'that perch on the side slopes J
and plateau of the partially closed"areas of the Subtitle D landfill. Additionally, ducks, geese, and 111
turtles tend to inhabit Sedimentation Pond 1.when stormwater is present. Beavers are indigenous to L ?
the area but have not been seen inhabiting the sedimentation basins. i
stormwater discharged through Outfall No. 1 is not impacted with leachate due to the capped
drainage areas of the Subtitle D landfill that channel runoff to Sedimentation Basin 1. Based on the
preliminary discussion with the DWQ, discharge through Outfall No. 1 may not be a regulated ,,ra�ld trm+l
discharge since there are no other potential.pollution sources_ other than wildlife: Therefore, Outfall 0(,'f1r6YW'�yf
No..1 should be removed from the monitoring program. �utT7i�S �S J

Compliance Schedule Correction
Onslow
Dear Dave Clark:
It recently came to the Division's attention that the compliance schedule in the NCG120000 permit is
incorrect. The compliance refers to requiring a Stormwater Pollution Prevention Plan which is not a
requirement of this permit. The corrected compliance language that should go under Part III, Section A: 1. is
shown below. We have also attached a new page reflecting this change for your permit file (Part III page 1 of
11). This new page should replace the current page in your permit.
SECTION A: COMPLIANCE AND LIABILITY
Compliance Schedule
The permittee shall comply with the permit in accordance with the following schedule:
Existing Facilities: Upon the effective date of the Certificate of Coverage the permittee shall comply
with all of the conditions detailed in Part 1I, Section A: Final Limitations and Controls for Stormwater
Discharges.
New Facilities: Upon the beginning of discharges from the operation of the industrial activity the
permittee shall comply with all conditions detailed in Part II, Section A: Final Limitations and Controls
for Stormwater Discharges.
If you have any questions concerning this matter please contact Aisha Lau at
[phone], ext. 578.
