In Reference to Stormwater Permit No. NCG020001
Wake Stone Triangle Quarry
Dear Mr. Lee:
Dee Freeman
Secretary
On July 9, 2010, Myrl Nisely and Lauren Witherspoon of the Raleigh Regional Office (RRO) of the NC
Division of Water Quality (DWQ) conducted a site inspection of the Wake Stone facility located
northwest of the intersection of Harrison Avenue and I-40 in Wake County, North Carolina. Mr. Paul
Pearce accompanied us during the site visit.
DWQ personnel made this site inspection in response to a complaint received by the RRO which
indicated that turbid water was leaving the site via a road outside of the facility. It is our understanding
that the road is maintained by the NC Department of Transportation (DOT).
During the site inspection, DWQ primarily focused on this DOT maintained road and the water leaving
the site at the location. The following observations were made:
A sprinkler system has been installed by the facility along the road for dust control. As a result of
this constant source of water and contact with dust from trucks leaving the site, turbid water was
observed in a ditch adjacent the road. DWQ evaluated the ditch and the area down gradient of the
ditch. The ditch flows into an area with hydric soils, wetland hydrology, and hydrophitic vegetation.
These criteria usually indicate the presence of a wetland. However, DWQ believes that the area
would not have wetland characteristics if it were not for the source of water from the sprinkler
system. Trace sediment (<2 inches) was observed in places from near the fence to approximately 30
feet from the fence property line. This area was stable with plush vegetation (Microstegirr»z sp)

growing throughout. After walking further down -gradient. DWQ believes that this area is not
contiguous with waters of the state (a large wetland system which is connected to Crabtree Creek).
We do not recommend removing the trace sediment in the area down gradient from the road because
disturbing the well established vegetation would provide unnecessary disturbance_. We believe the
sediment has not traveled very far and is not reaching the large wetland system.
It is our understanding that you maintain the ditch adjacent to the road by removing accumulated
sediment as needed. in addition, we can see that the fence is helping prevent sediment from moving
offsite. Therefore, please continue to clean the ditch as needed and leave the fence in place. The present
volume of water is apparently effective in moving the suppressed dust from the road. If the sprinklers
were attenuated, a proposal being considered by Wake Stone, a buildup of silt and mud on the road is
likely. Therefore, DWQ recommends leaving the sprinklers as they are now configured.
While this release point is outside the responsibilities of your stormwater permit, we request Wake Stone
to conduct qualitative monitoring at this location semi-annually to monitor the need for sediment
removal and to identify any undesirable changes in what is presently a fairly effective BMP.
Thank you for your cooperation in this matter. If you have any questions or wish to discuss these issues
further please do not hesitate to call Myrl or me at [phone].

Wake Stone Triangle Quarry
Wake County
Dear Mr. Lee:
Dee Freeman
Secretary
On November 24, 2009, I made an inspection of the stormwater program for the Triangle Quarry located
at 222 Star Lane, Cary. The help of Mr. Paul Pierce and Mr. Mike Williams was greatly appreciated. I
then met you at the Knightdale office that afternoon to review the stormwater analytical results. At that
time we also discussed a draft of the upcoming NCG020000 permit renewal.
The quarry personnel provided a Stormwater Pollution Prevention Plan (SP3) typical of other general
permits, even though the current NCG02 only requires a BMP summary. All of the permit activities are
being carried out, and the program is being given excellent attention, including employee training.
Stormwater is captured by several small retention ponds. BMP structures are being well maintained,
and a new pond had been constructed only two weeks ago. Analytical values for TSS and Turbidity are
a problem, however. In spite of having several plateaus built into the perimeter of the mine in which
rainwater can spread and the velocity reduced so solids settle before water reaches the ponds, the
discharges from some of the ponds failed to meet cut-off concentrations for those parameters. The new
permit will contain an obligation to explore ways of meeting TSS (and perhaps Turbidity) targets
through Tier 1 and Tier 2 activities. The new permit will also require creation of an SP3, but your
company already has done so.
If you have any comments or questions about this inspection, please contact me at 919-791-4255 or

This letter is in response to your inspection report dated Tune 17, 2015 in which you detailed
deficiencies that you noted from your Compliance Evaluation Inspection of our tTriangIFQuarry1
on June 3, 2015, Thank you for helping us to identify areas in our stormwater pollution
prevention plan (SPPP) that need improvement. We are currently in the process of reviewing all
of our SPPPs in preparation for the implementation of the new NPDES General Permit. It is our
intention to not only rectify the deficiencies you pointed out (documentation of annual training
and annual review of the SPPP, and a table or summary of secondary containment inventory).
but also to better organize and clearly mark the location of each item required by the Permit.
Going through the SPPP with you and having a copy of the inspection checklist that your
department uses will be very helpful in making these improvements to our stormwater pollution
prevention plans.
You have also asked that we address in this response our shortcoming of analytical monitoring
frorr_ our Stormwater Discharge Outfalls (SDOs). I Hope it was clear to you during your site
inspection why collecting samples at all of our SDOs semi-annually is simply not possible. We
will however make sure going forward that we collect analytical samples from SDO 003 as
required by the Permit, and we will continue to monitor and attempt to collect samples from
other SDOs and make our best effort to document those attempts for those SDOs that rarely, if
ever, discharge. We are also actively investigating the feasibility of vegetating our perimeter
access road to see if we can eliminate SDOs 004 and 005.
Thank you again for your time and for participating in this `'multimedia" inspection. We
appreciate all of your input and recommendations. We take compliance with all of our permits
very seriously, and we are always looking for ways to improve.
Sincerely,

Dear Mr. Bratton:
Donald R. van der Vaart
Secretary
Staff from the Department of Environmental and Natural- Resources conducted a stormwater inspection
on June 3, 2015, as part of a multimedia inspection of your facility. The assistance provided by Mr.
John Bratton, Mr. David Lee, Mr. Cole Atkins, and Mr. Paul Pierce during the inspection was greatly
appreciated. The inspection report is attached. Findings during the inspection were as follows:
1. Certificate of Coverage (COC) No. NCG020001 under NPDES general permit NCG020000
was issued to Wake Stone Corporation — Triangle Quarry to discharge stormwater runoff and
process wastewater to Crabtree Creek, a Class-C NSW stream, in the Neuse River Basin.
2. The facility has developed and implemented a stormwater pollution prevention plan (SPPP).
A review of the plan indicated that it covered many components required by the general
permit. The following deficiencies were noted:
• Employee training has not been conducted and documented;
• The plan has` not been reviewed or updated annually;
• The plan lacks a summary or table of secondary containment.
3. Qualitative monitorittLY�has been conducted as required by the permit at outfalls that were
active. It was noted that analytical monitoring was not conducted in 2011 and 2014.
There have been no discharges from Stormwater Discharge Outfalh (SDOS) 005, and
006 in the past years, because of the relatively small drainage areas and settling basins
at each outfall. It is recommended that the facility continue the effort to sample at these
two outfalls. If no discharges occur during a semi-annual period, report "no flow" on
the annual monitoring report. Sampling at.SDO 003 must be conducted semi-annually,
as water from the big pond regularly discharges through a rock dam at the outfall.
4. SDOs 005, 006, 003, and the skimmer basins (effluent goes to SDO 003) were observed

Compliance Evaluation Inspection
On June 3, 2015, I and the three NCDENR colleagues listed above conducted a multimedia inspection at
the Wake Stone Corporation quarry located at 222 Star Lane in Cary, NC. The facility operates one shift
and is staffed with thirty-five employees. Buiidings'located on the site include an office area, quality
control lab, in room, storage building, and maintenance building. Rock is mined from an open pit
and brought to a processing area where it is crushed into small pieces by primary and secondary
crushers.
A tour of facility operations was conducted during the visit. Waste Streams at the facility includes used
oil, used antifreeze, batteries, mercury containing lamps, aerosol cans, and solvent wipes. Batteries are
exchanged for core recyclinj once they are generated through interstate batteries.
Used oil is accumulated in above ground storage tanks and in several smaller' containers. The facility
contracts with Safety-Kleen for collection of used oil for recycling and maintains receipts. A parts
washer is located within the maintenance shop area and is maintained by Safety-K1een. The parts washer
uses Non -Hazardous Safety-Kleen Premium Gold solvent. The used solvent rags are, stored within a
closed container and are sent off for laundering. No empty aerosol cans or used lamps were observed

(II) FACILITY DESCRIPTION: Wake Stone Corporation — Triangle Quarry is a crushed stone (granite)
quarry. This facility operates under Air Permit 04386RI5 which was issued on August 30, 2013 and expires on July
31, 2021.
(III) SPECIAL SAFETY NEEDS: This is a quarry which is under the Federal Mine Safety Health Administration
(MSHA). For this reason, it is illegal for an inspector to tour this property without an MSHA approved escort (such as a
company official). The inspector is required to comply with all MSHA safety rules, especially those dealing with personal
safety equipment (they can be held liable for the fine and possible jail time).
Vehicles are required to be chocked, unless they are parked in a manner that if their parking brake fails, the vehicle will roll
into an embankment.
Required safety equipment includes safety shoes, a hard hat, safety glasses, and a safety vest.
(IV) INSPECTION SUMMARY: On June 3, 2015, Thad Valentine (DEMLR), John Holly (DEMLR), Cheng
Zhang (DWR), Andrew Martin (DWM), and I (Lori Ann Phillips) inspected Triangle Quarry in Cary.
We arrived at the quarry around 9:00am and met with Paul Pierce (Plant Superintendent), John Bratten (Owner),
David Lee (Environmental Supervisor), and Cole Atkins (Geologist/Environmental Specialist) for the purposes of
conducting a multi -media inspection. This report will detail the air quality permit -related inspection only. We met at
