Subject: NPDES Stormwater Compliance Evaluation Inspection
Certificate of Coverage No. NCG020001
Wake Stone Corporation — Triangle Quarry
Wake County
Dear Mr, Bratton:
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 monitoririg)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 Outfalls (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

during the inspection and found to be in good condition. The facility does not discharge

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. Buildings located on the site include an office area, quality
control lab, training 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 recycling 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-Klecn. 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

hazardous waste for off -site transport and disposal. Guidance documents for hazardous waste
generators can be found at: http://l2ortal.nrdeiir.org/web/wm/hw/Technical
It is a reminder that any container that is used to store or contain used oil must be labeled with the
words "Used Oil."

total suspended particulates.
b. Fugitive dust emissions from sand, gravel, or crushed stone operations shall be controlled by
15A NCAC 21) .0540 "Particulates from Fugitive Dust Emission Sources."
c. The Permittee of any sand, gravel, or crushed stone operation shall control process -generated
emissions:
i. From crushers with wet suppression; and
ii. From conveyors, screens, and transfer points
such that the applicable opacity standards in 15A NCAC 21) .0521 Control of Visible Emissions,"
or 15A NCAC 2D .0524 "New Source Performance standards" are not exceeded.
In compliance. No particulate matter or visible emissions were observed at this facility.
Triangle Quarry uses wet suppression to control VE and there was evidence that the spray
system was working correctly and doing its job.
A.5. The primary crusher is a jaw crusher rated at 1620 tons per hour at 16 inch crusher setting per the
manufacturer's specification as submitted. Any change from this crusher definition, other than

characterize the primary crusher and not limit production. In compliance. The primary crusher
has not been replaced or modified.
A.6. VISIBLE EMISSIONS CONTROL REQUIREMENT - As required by 15A NCAC 2D .0521,
visible emissions from the emission sources, manufactured after July 1, 1971, shall not be more
than 20 percent opacity when averaged over a six -minute period. In compliance. Visible
emissions were not noted at the time of the inspection.
A.7. VISIBLE EMISSIONS CONTROL REQUIREMENT - As required by 15A NCAC 2D .0521,
visible emissions from the emission sources, manufactured as of July 1, 1971, shall not be more

(IX) 112 R: The facility has not triggered this set of rules.
(X) COMPLIANCE HISTORY: There were no NOVs or other compliance issues listed in the IBEAM
database for this facility.
(XI) PERFORMANCE TEST REVIEW: No testing has been done in the last 5 years.
(XII) EMISSIONS INVENTORY REVIEW: Changes in reported PM and PMio emissions from 2007 to 2012
are due to differences in calculating the facility -wide PM emissions as documented in the emissions
inventory report.
(XIII) CONCLUSIONS AND RECOMMENDATIONS:
At the time of the inspection, the facility appeared to be in compliance with the permitting requirements.
Recommend inspection within two years.
