Stacey,
I'm working on a response letter from our office regarding this request. I wanted to verify the contact information for
the permittee so I can address the letter appropriately. Please see attached — is the letter best addressed to John
Pfleger or Ralph Ford, or another individual?
Also, my supervisor retired yesterday, and we have not just a smaller set of staff, but we also have no immediate
supervisor. I'm doing my best to get a response completed and signed by my section manager as soon as possible, but
we will be juggling a lot of issues in the interim. Please check in if you don't hear from me by mid -March.

Bethany,
Based on our observations and data, we have no objection to your decision to alter the Waste Industries monitoring
plan.
We concur with your assessment that Waste Industries has made a good faith effort at maintaining best management
practices to control sediment discharge from their site. Also, my experience inspecting the site in -person confirms your
GIS observation of a long distance between the facility discharge and surface waters.
Our closest stream monitoring site is located approximately four miles downstream of Waste Industries. Attached,
please find a report of our monitoring results prepared by City of Durham Water Quality Specialist Susan Gale. Susan
reaches a similar conclusion that, while there are some elevated TSS and turbidity values observed, the distance
between the monitoring site and Waste Industries makes it unlikely that the facility is contributing to the sediment load.
Feel free to contact us if you need further assistance.
Thanks,
Jim Azarelo

NPDES Permit NCG080845
Relief from Advanced Tier Response
Durham County
Dear Mr. Pfleger:
We are writing in response to the request we received from Smith+Gardner, Inc. (Mr. Don
Misenheimer) on behalf of Waste Industries, LLC-Durham on May 13, 2016. The request
outlined the efforts by the company to remedy Total Suspended Solids (TSS) benchmark
exceedances since 2014, and made the case that substantial corrective efforts and costs
already incurred by the company, as well as the constraints of the property and prohibitive
costs of additional measures, justify relief from monthly TSS monitoring.
Based on our review and consideration of the request, the DEQ Stormwater Program is
granting regulatory relief from monthly TSS monitoring as part of its Tier 2/Tier 3
response. Waste Industries, LLC-Durham may resume semi-annual analytical monitoring
for the remainder of the current permit term, which ends October 31, 2017. This decision
applies only to the TSS benchmark. A benchmark exceedance of any other parameter
listed in your permit will trigger the tiered response actions as described in your
permit. Upon renewal of General Permit NCG080000, the company may continue semi-
annual monitoring in accordance with this relief for TSS benchmark exceedances, unless
site circumstances or industrial activities change to increase TSS pollution potential (or
other parameter benchmark exceedances prompt more frequent monitoring).
State of North Carolina f Environmental Quality I Energy, Mineral and Land Resources
512 N. Salisbury Street 1612 Mail Service Center I Raleigh, North Carolina 27699-1612
919 707 9200

The relief granted in this letter is also contingent upon continued site management
improvements designed to reduce and prevent TSS in stormwater discharges from Waste
Industries, LLC-Durham. If industrial practices change, site maintenance declines, water
quality standards in the receiving water are impacted, or if other activities occur that
worsen the level of suspended solids in the stormwater discharges from this site, this office
reserves the right to withdraw this decision and reinstate the permit specified tiered
response -or other actions that may be warranted by the new set of circumstances.
Please retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP)
or permit. Should you have questions or comments regarding this letter, please contact
Bethany Georgoulias at [phone] or [e-mail].

Toby Vinso

Subject: Waste Industries LLC - Durham
Good morning, Jim,

Our office is handling a long -overdue response to Waste Industries, LLC in Durham (NCG080845) regarding their request
to reduce TSS monitoring given the constraints for further treatment options and efforts implemented to date (see
attached). We apologize for the delay in attention to this; the Raleigh Regional Office is still without a supervisor and
hasn't had staff to follow up on this for quite some time ...and as of the start of the month, we are without a supervisor
in the Central Office, too.
I've followed up with the consultant about some questions I had and touched base with RRO (Thad Valentine is now
focusing on Stormwter Program issues in that office), and we agree they've implemented improvements and made a
good case to return to a semi-annual sampling schedule as long as other management efforts to prevent stormwater TSS
continue. However, before we finalize the letter, f wanted to check in with you about any water quality impacts.
From my GIS resources, it looks like this facility's discharges travel some distance before reaching a UT to Northeast
Creek. Were or are there any immediate impacts from suspended solids in the surface waters that we should be aware
of before proceeding with relief for their monthly monitoring? Any apparent water quality standard violations that
resulted from these elevated sample numbers could make us reconsider our decision. Otherwise, we will proceed with
approval of their request.
Thanks,
Bethany

Summary of ambient monitoring data, Northeast Creek downstream of Waste Industries
Prepared March 8, 2017
Susan Gale, Water Quality Specialist, City of Durham Stormwater and GIS Services
The facility in question (Waste Industries) is located north of Stone Rd. at approximate coordinates
35.94905/-78.85441. The waterbody closest to the facility is an unnamed tributary that drains to
Northeast Creek. The City of Durham has two ambient monitoring locations on Northeast Cr.: one at NC
54 (Site # NE1.2NE) and the other at Sedwick Rd. (Site # NEO.ONE) (Attachment 1). NE1.2NE is the most
upstream site, though it is located approximately 4 miles downstream from the facility in question. Land
use immediately adjacent to Northeast Cr. itself is largely forested, but many areas of the watershed
between the facility and monitoring station appear to be fairly densely developed with a mix of
industrial, commercial, and residential land uses.
Site NE1.2NE is sampled during even calendar years. Water quality results were obtained in March 2017
from the City of Durham water quality data portal (www.durhamwaterguality.org) for 2014 and 2016,
the last two years when monitoring occurred. Results for both total suspended solids (TSS) and turbidity
are summarized below. Raw data are included as a table at the end of this document (Attachment 2),
The two graphs below provide a time series of TSS (mg/L) and turbidity (NTU) results for January 2014 —
December 2016. Marker color is based on field observations: red markers indicate rain occurred in the
previous 24 hrs., and green indicates dry conditions during the preceding 24 hrs. While elevated results
are to be expected during and after rain events in urban streams such as Northeast Creek, there were
several instances of elevated values during dry conditions. However, these are likely not attributable to
the facility in question, due to the distance between the monitoring site and the facility.

Subject: RE: Durham Campus Update Letter
Stacey,
We will respond to this request from the Central Office and copy the Raleigh Regional Office on any
correspondence. Given the absence of a Supervisor there right now, and the history Ken Pickle had with knowledge on
this site, as well as the information provided in the correspondence from May 13, 2016, our office can provide a
determination.
I do have a few questions as I'm catching up on the details of Waste Industries' situation:
-How many outfalls are at this site? From 2015 DMRs I was able to access and the info in the report, it appears there is
just outfall 001, but I wanted to verify that. Yes, there is just one outfall.
-Wham with the City of Durham should we copy, to keep their program updated on DEQ determinations for this
site? The City Stormwater contact is Jim Azarelo [e-mail]
-Did the company consider any innovative Stormwater devices as alternatives? For example, StormFilter by Contech is
now included in the Stormwater Design Manual in Part D. 1 as a device that removes TSS (and with certain media,
nurtrients). I'm not recommending this device —I'm also not familiar with the design or siting requirements in much
detail because it's normally used in the context of post -construction permitting —and perhaps a proprietary treatment

device would be just as expensive or futile here, but i am asking if any proprietary devices were entertained during the
evaluation process. The City of Durham may have experience with these or other devices in their post -construction
program and have thoughts on it, if this is even an avenue worth considering. (Maintenance would be a large
consideration, given the nature of the TSS loading in large events.) We did utilize filter bags in the boxes, some
regrading, and to position the sampling location to allow the stormwater to settle out. We also looked at constructing a
bioretention area. We believe the issue is that the flow is concentrated to a single outfall and the entire site was
designed at a time in advance of the current practice with stormwater quality. The runoff in a 10-year/24-hour storm is
+/-100 cfs. In review of Storm Filter®, it does not appear to be able to manage that much flow or a reasonable cost.
Thanks,
Bethany

Bethany,
This is the letter that we sent to John Holley and our correspondence.
Our client, Waste Industries, wants to and intends to remain responsive to this situation, but would like some
acknowledgement that until DEQ has sufficient time to review and further discuss options, that the site may
remain in compliance until further notice.
Beyond our initial letter to John Holley, 1 have only contacted him by phone. The last time was immediately
following our last converation.

RE: Reduction of Monitoring Frequency - Evaluation/Request
Waste Industries, LLC — Durham
Certificate of Coverage #NC6080845
General Permit#NCG080000
Dear Mr. Holley:
On behalf of Waste Industries, LLC - Durham Facility, Smith Gardner Inc. (S+G) is submitting
this request/evaluation to the Division of Energy, Minerals and Land Resources - Stormwater
Permitting Program (Division) that a reduction in monitoring frequency be granted. We
understand that the purpose of increased monitoring is to gather data for evaluation, not
merely for monitoring sake. We believe that the site has compiled enough data to evaluate
corrective actions taken and proposed on -site, therefore making the increased frequency of
monitoring unnecessary.
This document includes/evaluates monitoring data, costs and feasibility (actual and
projected) of corrective efforts attempted/evaluated/rejected on -site. We believe that this
evaluation'shows that the effort put forth by Waste Industries has been substantial and that
additional effort, other than general site management items, is not warranted at this time - 'A
drawing showing the existing site conditions is provided as Sheet 2 in the approved Level 3
Site plan which is provided in Attachment 1.
CURRENT PERMIT STATUS
In December 2013, the facility officially entered Tier 2 status (NPDES General Permit for
Transit and Transportation) after twice exceeding the TSS benchmark value of 100mg/l.
After the February 2014 monitoring event, the facility entered Tier 3 status for TSS and
official notification to the Division was made in July 2014, including the plan for the
installation of a Stormwater detention basin on -site. The last official update to the Division
was made in November 2015 and notified of a potential change in the location of the;
permitted basin to a newly acquired parcel to the south (evaluation results of this new
location are discussed below).
Subsequently, in December 2015, an inspection and meeting at the site took place with the
City of Durham Stormwater staff. Before the site moves forward with more effort, the City '
has stated that they will defer to, and agree with, the Division's decision on the reduction of
monitoring requirements, as well as, the amount of effort required to address this TSS issue.

The City has asked S+G to keep them informed so they can add the Divisions comments on
this matter to their file. S+G contacted the Division in February 2016 to discuss this matter
and the possible submittal of this request.

Additionally only qualitative monitoring was performed during February, March and April
2016 as no events occurred where the first flush could be sampled and stormwater flow
appeared typical of recent sampling events.
Data Correlation
S+G attempted to correlate gathered data with the below corrective efforts/site
maintenance items. Direct correlation could not be found as the size of the storm
event/velocity of stormwater appears to be the driving force for the TSS issue. These
types of events often over power on -site maintenance measures taken, making a
reliable data correlation impossible.
CORRECTIVE EFFORTS
The site has attempted/evaluated or rejected the below methods of corrective actions. The
site has been responsive and thorough in the attempts to address this issue, and provides
the following information as an evaluation of such effort.
Site Maintenance Items
Several general site maintenance options have been implemented at the site to
attempt to reduce the TSS levels. Below is a list of several improvements that have
been utilized on -site:
• Re -grading of parking lot near drop -inlet;
• Use of sediment collection bags in drop -inlets;

Mr. John Holley, P.E.
May 13, 2015
Page 3of6
• New aggregate with fabric placement at select areas of parking lot;
• Installation of rip -rap channels in high flow areas;
• Check -dam installation;
• Wattle placement; and
• Movement of outfall location.
These options appear to make overall improvement in the amount of sediment
leaving the site, but only during very low flow events (less than 0.171. The large
volume of run-off typically present at the site appears to "over -power" these installed
options. While Waste Industries and S+G continued to evaluate these methods,
additional design methods were evaluated and are discussed below.
Skimmer Installation
S+G evaluated the installation of a riser and a Faircloth skimmer at the original
outflow culvert. This riser/skimmer would be constructed without building a pond,
and would be located at a low area north of Stone Park Court that is the invert to the
discharge culvert (location shown on Attachment 21. This option was modeled (using
the runoff from a 1-year storm event) as a mini -pond, to determine if the skimmer
could slow down discharge sufficiently to allow some of the suspended particles to
settle. However,�due to the drainage area (more than 10.8 acres), even the 1-year
storm event overwhelms the skimmer and discharges through the culvert in less
than 2 minutes. This calculation seems accurate. The total storage available in the
"low area" near the culvert is approximately 5,000 cubic feet, white a 1-inch runoff
from the drainage area has a volume of nearly 40,000 cubic feet. The available
storage is not significant, compared to the potential runoff volume. This method was
rejected.
Flocculent Installation
Installing/utilizing flocculants on -site were considered for treating the runoff. It was
determined that the high velocity and amount of flow that is typical on -site would not
allow for proper mixing/dosage to occur. Additionally, it is possible that flocculent
use at this site could lead to greater sediment deposition off -site due to outfall
Location and run-off velocity/ amount. This method was rejected.
Biorelention Areas
Bioretention areas were considered for filtering the runoff. Two available areas were
identified on each side of the driveway access to the administrative/maintenance
building (shown on Attachment 2). The areas were each about a quarter of an acre,
which was too small for the contributing run off area. Additinally, about 75% of each
potential area was within the required buffer (City of Durham) to Stone Park Court, so
they could not be available to use as bioretention areas. This method was rejected.

Mr. John Holley, P.E.
May 13. 2016

lot Paving
While it is possible that this option may improve the runoff quality, it will likely
'increase the run off quantity. The quantity increase may lead to increased erosion
further downstream. The cost of this option is also substantial (cost breakdown is
included as Attachment 3). Combinations of these factors lead this method to be
rejected.
Permitted Basin North of Stone Park Court
S+G and Waste Industries decided that a basin installed on -site would be the only
feasible and most effective way to address the TSS issue. Subsequent to the
notification to the Division of Tier 3 status, S+G began the City/County of Durham
submittal process for approval of the basin which required a Level 3 Site plan
(Attachment 11. The process took eight (8) months and approval was granted on
March 31, 2015. Items related to the design/permitting/cost of the basin are
discussed below:
• Available Space
Conceptually, the basin was limited due to the available area for the basin.
An initial idea was to construct a wet basin in the area north of Stone Park
Court, but there was not sufficient space to allow for a forebay, a littoral
shelf, or the other features needed for a properly functioning wet basin.
Therefore, the conceptual plan was to construct a dry basin with a
skimmer for outlet control: This would slow the discharge and allow the
suspended particles to settle.
Existing Culverts
The permitted basin was constrained by three existing culverts. Two
culverts flowing into the proposed basin area from the east side, and a
single culvert which discharges underneath Stone Park Court to the south.
In design, the bottom of the basin was restricted by the elevation of the
outflow culvert (EL 368). Installing a culvert at a lower elevation would be
prohibitively expensive, due to the road with water, sewer, and other
underground utilities. The maximum water elevation in the basin was
limited to prevent submerging the incoming culverts, which could cause
overflow issues at the upstream drop inlets. The maximum water
elevation was limited to EL 377 to prevent overflow in the upstream drop
inlet.
• Stone Park Court
The size and maximum elevation of the pond was limited by the elevation
of Stone Park Court (approximately E1375), The permitted basin included

Mr. John Holley, P.E.
May 13, 2016
Page 5 of 6
building up the embankment near Stone Park Court to EL 377, as both a
visual screen and a means to increase the freeboard in the basin.
Setback requirements
The basin was designed to hold the approximate volume of runoff from a
10-year, 24-hour storm event. However, due to tree canopy requirements
and to set -back limitations, the potential area for a basin was restricted.
The'resulting proposed volume was equivalent to approximately the runoff
volume from a 6-year, 24-hour storm event.
• Rock
After design restrictions and eventual permitting of the basin, an
investigation to determine bedrock depth was conducted in the fall of
2015. Bedrock was determined to be from 3-7 feet in areas of the
proposed basin. The rock elevation further minimized the cut available to
shape the proposed basin.
• Cost
Waste industries has spent close to $70,000 on the basin
design/permitting, bid procurement, required surveys, and investigations
associated with this basin. Bids received to construct the basin were from
approximately $300,000 to $350,000 for the base bid price. An alternative
included to remove soils from site (an on -site stockpile area is not
available) increased the bids to approximately $416,000 to $516,000.
This basin was ultimately rejected just before construction was to begin in the fall of
2015 due to the bedrock restriction discussed above.
Basin 0 tian South of Stone Park Court
Subsequent to the determination that the originally proposed basin Location would not
be suitable, Waste Industries purchased the property to the south of the facility (Lot 4
shown on Attachment 21. Conservative preliminary estimates showed this lot as a
suitable new location for a proposed basin. A site evaluation was performed
including wetland and stream investigation, depth to rock and required basin size.
Available Space
S+G utilized data obtained in a wetland and stream investigation, depth to
rock investigation to develop options for a sediment basin size and
Location. To achieve the stated goal of TSS removal, the 10 year 24 hour
storm event was chosen as the design storm parameter. Analysis of this
storm event resulted in approximately 151,000 cubic feet of required
storage to fully capture the design storm. Scenarios were evaluated, with
each having sufficient capacity to hold the 10 year storm event. However,
depth to rock is similar in this area (outcrops to 8 feet deep). There are

storm event resulted in approximately 151,000 cubic feet of required
storage to fully capture the design storm. Scenarios were evaluated, with
each having sufficient capacity to hold the 10 year storm event. However,
depth to rock is similar in this area (outcrops to 8 feet deep). There are
also potential wetland issues that would need to be designed around. A
preliminary figure relating to this basin is provided as Attachment 4,
Costs
Costs for this basin are estimated to be similar to the basin previously
discussed. The design and permitting approval through Durham
City/County would need to be repeated with another Level 3 Site Plan. S+G
estimates $50,000 to $70,000 on the basin design/permitting, bid
I rocurement, required surveys, and investigations associated with this
basin. Construction estimates for this basin are similar to the previously
approved basin with a base price of approximately $350,000 to $500,000.
For this basin project to move forward, an additional, substantial financial
commitment would have to be made by Waste industries. The site would have to go
through the design and permitting process again, with no guarantee of approval by
the City/County of Durham.
CONCLUSION/REQUEST
We believe that this evaluation shows that the effort put forth by Waste Industries has been
substantial and that additional effort, other than general site management items, is not
warranted at this time. We propose that the frequency analytical monitoring on -site be
reduced to semi-annually, as we understand that the purpose of increased monitoring is to
gather data for evaluation, not merely for monitoring sake. The site will continue to
implement best management practices and wilt continue on monthly monitoring schedule
until a decision is made by the Division on this matter.

Hi Don,
So, a couple of the elements for Waste Industries are a little out of the box — the Regional Office agreed with your plan,
but site conditions did not cooperate; the lag time is unusual because of the Durham review. With those unusual
aspects in mind:
if you don't mind, please copy me on the follow-up this year with John Holley. I'll file it in our skeleton file up herein the
stormwater program so that if future questions arise about why things happened the way they did we will have the info.
Thanks,
Ken

RE: Tier 3 — Status Update

Certificate of Coverage #NC6080845
General Permit#NCG080000
Dear Mr. Holley.
Smith Gardner Inc. (S+G) has prepared this status update to the Division of Energy, Minerals
and Land Resources - Stormwater Permitting Program to inform you of the current status of
the planned improvements (basin installation) at the facility.
CURRENT NPOES PERMIT STATUS
In August 2012, the City of Durham required the facility to begin conducting monthly
monitoring of site stormwater due to high levels of TSS leaving the site. In December 2013,
the facility officially entered Tier 2 status (NPDES General Permit for Transit and
Transportation) after twice exceeding the TSS benchmark value of 100mg/l. After the
February 2014 monitoring even, the facility entered Tier 3 status for TSS and official
notification to the division was made in July 2014, including the plan for the installation of a
stormwater detention basin on -site (attached).

CURRENT PROJECT STATUS
Subsequent to the notification to the Division of Tier 3 status, S+G began the City/County of
Durham submittal process for approval of the basin (requiring a Level 3 Site plan). The
process took eight 18) months and approval was granted on March 31, 2015. Construction
was slotted to begin during the fall of the year. Pre -construction activities including surveys,
bid procurement, and further site investigation was performed in the interim. During an
investigation on -site, bedrock was determined to be from 3-7 feet in areas of the proposed
basin.
It was determined that the originally proposed location for the basin would not be suitable for
purpose of the design. Waste Industries has purchased the property to the south of the
facility ILot 4 shown on Figure 1 of the attached Notification Letter). Conservative
preliminary estimates show this tot as a suitable new location for the proposed basin. A site
evaluation is currently being performed including wetland and stream investigation, depth to
rock and required basin size.
After the current evaluation is complete, S+G will meet with the Durham City -County
Planning Department to discuss the project under the current approval. S+G will update this
Division with the outcome of that meeting.
Please contact me by phone [phone], ext. 224) or by email below with any questions or
comments.
Sincerely,
Smith Gardne I e.

ON -GOING SITE IMPROVEMENT STATUS
Several low-cost options have been implemented at the site to attempt to reduce the TSS
Levels at the site. These options have only shown limited improvement in levels of TSS
Leaving the site. The large volume of run-off, due to impervious surfaces and drainage area
size, appears to be "over -powering" these installed options. Below is a list of several
improvements that have been used on -site since August 2012:

• Re -grading the parking lot near the drop -inlet;
• Placing sediment collection bags in the drop-intets;
Installing new aggregate with fabric at selected areas of parking lot;
+ Installing rip -rap channels in high flow areas;
• Installing check -dam;
• Placing coir-fiber wattles in channels; and
• Moving the outfall monitoring location to the associated stormwater easement
associated with the site.
In April 2014, S+G took part in a conference call with Waste Industries to discuss additional
options to address TSS leaving the site. It was decided that S+G would perform conceptual
stormwater modeling and design work to explore the options of on -site storage at the
facility, including the analysis of pre- and post -development stormwater discharges from the
site outfall.
S+G was also tasked with reviewing City and County Ordinances, as well as, meeting with the
City/County to discuss any additional requirements/fees/submittals that may be warranted
for implementation of the conceptual design.
STORMWATER MODELING AND CONCEPTUAL DESIGN
S+G conducted site visits in April and June 2014 to verify the existing conditions to serve as
inputs for a HydroCAD model. Culvert sizes, as included in the as -built', were field checked
for accuracy while existing grates and drop inlet depths were measured.
S+G determined that enough valid information was present to proceed with a HydroCAD
model in the design process. One initial design investigated was for a small basin to be
constructed in an area on the eastern portion of the property that is currently used for
storing plastic trash/recycling bins. However, this initially designed basin would have
insignificant storage and therefore not be effective in removing sediment. Other ideas, such
as stormwater control wetlands were considered, but not enough land was available. The
idea of paving the parking lots was also explored, but rejected due to the expense and the
slight increase in the peak discharge that would be expected.
The most practical method to prevent future sediment from leaving the site is to build a
stormwater basin (basin) near the current discharge point. S+G elected to design a basin
that would hold nearly all of the run-off from a 10-year, 24-hour storm event. Because the
basin would be a permanent feature, the basin was also designed to route a 100-year, 24-
hour storm event without overtopping the banks. The proposed design creates the maximum
storage and retention time possible without relocating the permitted discharge point.

Stormwater Basin Design Information
The basin has a drainage area of approximately 15 acres. Most of the drainage area
(approximately 14 acres) is gravel parking area, access roads, or buildings. The basin
is designed to be constructed in the wooded area north of Stone Park Court (as shown
on the attached Figure 1). No excavation is proposed to impinge on the rights of
ways of the sewer easement or on the natural gas easement. The total depth of the
basin is shown to be excavated to eight (8) feet to the crest, but the western sides will
have longer slopes. The side slopes will be at 2.5H:1V.
The proposed basin will discharge through existing 18-inch diameter RCP culvert that
runs under Stone Park Court. The existing culvert will be extended as necessary to
connect to a new 4'x4'x6' concrete riser (Figure 2 attached). A Faircloth skimmer
will be installed at the base of the concrete box. The top rim of the box will be
approximately six (61 feet above the invert of the existing culvert. The rim of the box
will function as the principal spillway for the basin, creating a surface area of
approximately 0.75 acres at the rim elevation. A grass -lined, emergency spillway is
proposed to be constructed in existing ground (approximately 1-foot higher than the
top of the concrete box). Any flow from the emergency spillway will discharge
directly to the property (also owned by Waste Industries) south of the facility;
however, no flow is expected in the emergency spillway in a 100-year storm event.
The proposed basin design will significantly reduce the discharge from the site, as
shown on Chart 1. Most storm events will discharge entirely through the Faircloth
skimmer at a constant rate of approximately 0.2 cubic feet per second (CFSI. Larger
storm events will pass over the rim of the principal spillway. For example, in a 10-
year, 24-hour storm event (i.e., 5.01 inches of precipitation in 24 hours), the existing
conditions are calculated to generate a peak discharge of approximately 97 CFS.
With proposed basin, the same storm event would discharge less than 2 CFS. In a 25-
year, 24-hour storm event (5.93 inches or rain), the peak discharge is reduced from
118 CFS to 6 CFS.
Reducing the peak discharge and storing water in the basin will allow sediment to
settle before the water leaves the site. During a 25 year storm event, the calculated
settling efficiency of the basin is more than 95%.
PERMITTING AND ZONING REVIEW (CITY/COUNTY OF DURHAM)
In June 2014, S+G met with the City of Durham (Planning/Zoning Department and
Stormwater Services) and Durham County (Engineering) to discuss the conceptual design.
Fees, submittals, and other requirements that would be foreseeable were discussed during
these informal meetings. The results of which are discussed below.
To construct the proposed basin, a Level 3 Site Plan will need to be submitted to the City of
Durham Planning Department. Subsequently, this plan will be reviewed by other City
departments including Stormwater Services. This Site Plan will include:

Mr. John Holley, P.E.

Page 4 of 4
• a letter report presenting the design summary and associated calculations;
• nutrient loading calculations (post vs pre development conditionsl;
• a drawing set; and
• an erosion and sedimentation control (E&SC) plan
Simultaneously, the E&SC plan will be submitted to Durham County Engineering which will
start a 30-day "timer" to begin construction.
CURRENT PROJECT STATUS
Currently, the design is being reviewed and finalized as preparation for submittal to the City
and County of Durham, for approval. Waste Industries continues to be pro -active in
addressing these stormwater issues present on -site. S+G will notify the Regional
Administrator as the design is finalized, subsequently approved, and constructed.
Timeline
The City Planning Department will take up to 30 days from day of submission to
respond. Most likely there wit( be one round of comments followed by another 30
days for Planning to respond. Subsequently final submittal copies of the plans wilt be
submitted for Planning to issue a final approval. S+G estimates this process to take
2-3 months.
The submittal to County Engineering turnaround should be fairly quick, approximately
30 days. Please note that these items are submitted simultaneously.
Construction time may take up to a month. Overall. S+G estimates a timetine of 5-6
months until project completion. S+G wit[ provide an updated timeline as this project
proceeds.

• Installing rip -rap channels in high flow areas;
• Installing check -dam;
• Placing coir-fiber wattles in channels; and
• Moving the outfall monitoring location to the associated stormwater easement
associated with the site.
In April 2014, S+G took part in a conference call with Waste Industries to discuss additional
options to address TSS leaving the site. It was decided that S+G would perform conceptual
stormwater modeling and design work to explore the options of on -site storage at the
facility, including the analysis of pre- and post -development stormwater discharges from the
site outfall.
S+G was also tasked with reviewing City and County Ordinances, as well as, meeting with the
City/County to discuss any additional requirements/fees/submittals that may be warranted
for implementation of the conceptual design.
STORMWATER MODELING AND CONCEPTUAL DESIGN
S+G conducted site visits in April and June 2014 to verify the existing conditions to serve as
inputs for a HydroCAD model. Culvert sizes, as included in the as -built'; were field checked
for accuracy while existing grates and drop inlet depths were measured.
S+G determined that enough valid information was present to proceed with a HydroCAD
model in the design process. One initial design investigated was for a small basin to be
constructed in an area on the eastern portion of the property that is currently used for
storing plastic trash/recycling bins. However, this initially designed basin would have
insignificant storage and therefore not be effective in removing sediment. Other ideas, such
as stormwater control wetlands were considered, but not enough land was available. The
idea of paving the parking lots was also explored, but rejected due to the expense and the
slight increase in the peak discharge that would be expected.
The most practical method to prevent future sediment from leaving the site is to build a
stormwater basin (basin) near the current discharge point. S+G elected to design a basin
that would hold nearly all of the run-off from a 10-year, 24-hour storm event. Because the
basin would be a permanent feature, the basin was also designed to route a 100-year, 24-
hour storm event without overtopping the banks. The proposed design creates the maximum
storage and retention time possible without relocating the permitted discharge point.

Stormwater Basin Design Information
The basin has a drainage area of approximately 15 acres. Most of the drainage area
(approximately 14 acres) is gravel parking area, access roads, or buildings. The basin
is designed to be constructed in the wooded area north of Stone Park Court (as shown
on the attached Figure 11. No excavation is proposed to impinge on the rights of
ways of the sewer easement or on the natural gas easement. The total depth of the
basin is shown to be excavated to eight (8) feet to the crest, but the western sides will
have longer slopes. The side slopes will be at 2.5HAV.
The proposed basin will discharge through existing 18-inch diameter RCP culvert that
runs under Stone Park Court. The existing culvert will be extended as necessary to
connect to a new 4'x4'x6' concrete riser (Figure 2 attached). A Faircloth skimmer
will be installed at the base of the concrete box. The top rim of the box will be
approximately six (6) feet above the invert of the existing culvert. The rim of the box
will function as the principal spillway for the basin, creating a surface area of
approximately 0.75 acres at the rim elevation. A grass -lined, emergency spillway is
proposed to be constructed in existing ground (approximately 1-foot higher than the
top of the concrete box). Any flow from the emergency spillway will discharge
directly to the property (also owned by Waste Industries) south of the facility;
however, no flow is expected in the emergency spillway in a 100-year storm event.
The proposed basin design will significantly reduce the discharge from the site, as
shown on Chart 1. Most storm events will discharge entirely through the Faircloth
skimmer at a constant rate of approximately 0.2 cubic feet per second ICFS). Larger
storm events will pass over the rim of the principal spillway. For example, in a 10-
year, 24-hour storm event (i.e., 5.01 inches of precipitation in 24 hours), the existing
conditions are calculated to generate a peak discharge of approximately 97 CFS.
With proposed basin, the same storm event would discharge less than 2 CFS. In a 25-
year, 24-hour storm event (5.93 inches or rain), the peak discharge is reduced from
118 CFS to 6 CFS.
Reducing the peak discharge and storing water in the basin will allow sediment to
settle before the water leaves the site. During a 25 year storm event, the calculated
settling efficiency of the basin is more than 95%.
PERMITTING AND ZONING REVIEW (CITY/COUNTY OF DURHAM)
In June 2014, S+G met with the City of Durham (Planning/Zoning Department and
Stormwater Services) and Durham County (Engineering) to discuss the conceptual design,
Fees, submittals, and other requirements that would be foreseeable were discussed during
these informal meetings. The results of which are discussed below.
To construct the proposed basin, a Level 3 Site Plan will need to be submitted to the City of
Durham Planning Department. Subsequently, this plan will be reviewed by other City
departments including Stormwater Services. This Site Plan will include:

Mr. John Holley, P.E.

Page 4 of 4
• a letter report presenting the design summary and associated calculations;
• nutrient loading calculations [post vs pre development conditions);
• a drawing set; and
• an erosion and sedimentation control (E&SC) plan
Simultaneously, the E&SC plan will be submitted to Durham County Engineering which will
start a 30-day "timer" to begin construction.
CURRENT PROJECT STATUS
Currently, the design is being reviewed and finalized as preparation for submittal to the City
and County of Durham, for approval. Waste Industries continues to be pro -active in
addressing these stormwater issues present on -site. S+G will notify the Regional
Administrator as the design is finalized, subsequently approved, and constructed.
Timeline
The City Planning Department will take up to 30 days from day of submission to
respond. Most likely there will be one round of comments followed by another 30
days for Planning to respond. Subsequently final submittal copies of the plans will be
submitted for Planning to issue a final approval. S+G estimates this process to take
2-3 months.
The submittal to County Engineering turnaround should be fairly quick, approximately
30 days; Please note that these items are submitted simultaneously_.
Construction time may take up to a month. Overall, S+G estimates a timeline of 5-6
months until project completion. S+G will provide an updated timeline as this project
proceeds.

Danny and I recommend that you go ahead and issue the NCG08 permit specifically for the Vehicle Maintenance part of
the site. The RRO request that you include in the permit cover letter:
1) The adjacent Transfer Station is not covered by this permit, 2) the RRO's expectations of the adjacent Transfer Station
is that exposed areas are to be addressed such that stormwater does not commingle with leachate/residuals from
offloading and truck traffic , and 3) if concerns at the Transfer Station are not or cannot be satisfactorily addressed
additional permitting may be required.

How's it going? The attached facility has submitted for coverage under NCG08. I don't see any problems with the
application but wanted to check if you had any comments on them. Maybe you have paid them a visit and that is what

HAZARDOUS DECOMPOSITION PRODUCTS:
Acetylene decomposes at high pressure to its constituent elements of carbon and hydrogen. Carbon monoxide
may be produced from burning.
Under certain conditions, acetylene forms readily explosive acetylide compounds when in contact with copper,
silver, and mercury. Therefore, use of acetylene and these metals, or their salts, compounds, and high
concentration alloys should be avoided.
The presence of moisture, certain acids or alkaline materials tends to enhance the formation of copper acetylides.
HAZARDOUS POLYMERIZATION:
Temperatures as low as 250°F (121°C) at high pressure, or at low pressure in the presence of a catalyst are
sufficient to initiate a polymerization reaction. The hazard here is that the polymerization normally liberates
heat and may, therefore, lead to ignition and decomposition of acetylene if conditions permit.
11. Toxicological Information
Low concentrations (10-20% in air) cause symptoms similar to that of being intoxicated. As a narcotic gas or
intoxicant, it causes hypercapnia (an excessive amount of carbon dioxide in the blood). Repeated exposures to
tolerable levels has not shown deleterious effects.
TCLo, human - Inhalation of 20 ppb inhaled has been shown to cause headache and dyspnea.
Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental
animals.
12. Ecological Information
No data given.
13.• Disposal Considerations
Do not attempt to dispose of residual waste or unused quantities. Return in the shipping container PROPERLY
