Subject: Stormwater Compliance Inspection
RDU Readymix & Asphalt Concrete Plant
NPDES Stormwater Permits NCG 140251 & NCG 160138
Raleigh, NC
Wake County
On December 22, 2005 Myrl Nisely and Ron Boone of the Raleigh Regional Office of Division
of Water Quality made a compliance inspection at Sunrock's RDU facility on Barefoot Industrial
Rd. We greatly appreciated the assistance given by Brian Birdsall and Fred Blankenship. A
follow-up visit was made on January 10, 2006 by Ken Schuster and Myrl Nisely.
At first look, the site appears to be non -discharge regarding process wastewaters, but appears to
have one Stormwater (SW) outfall. Upon further consideration, both ideas are incorrect, as
discussed below. The asphalt and ready mix plants are integral to each other, so this inspection
covered stormwater concerns for both. In fact, where a site contains both asphalt and concrete
such as this, only one SW permit is needed. We ask that Sunrock file a request for rescission of
the asphalt permit, NCG 160138.
There were a number of improvements needed in the Stormwater Pollution Prevention Plan. The
one SP3 can serve both industrial activities if modifications are made to tables and descriptions
to include all industrial activities. As a result of this inspection, the Division is also requiring a
re -definition of releases from the plant.
The flow of stormwater on the north end of the site is commingled with runoff from the last two
aggregate piles. This mixing causes that release to fall under the wastewater portion of the
permit, so must meet permit limits. The company should investigate a Best Management
Practice (BMP) to improve that release point, perhaps using a retention basin to assure TSS is
below 30 mg/l, assuming pH falls within the 6 to 9 limits.
This site is uniquely designed with the retaining wall along the entire west side, with industrial
activities directing water to a section of the plant located over several feet of aggregate. At first

observation, this arrangement would suggest that no process waters leave the site. However,
water percolates through the surface and emerges from under a layer of stone outside the wall.
Engineering principles suggest that a series of toe drains likely exist in the base of the wall to
relieve the water, but these are covered by uniform aggregate banked against the outside of the
wall. At several places the water travels from the rocks into the weedy area on its way to a
stream channel. Therefore, this facility does have releases of wastewater, albeit attenuated by
the material it must pass through before reaching the stream.
The Division feels that one of the larger release points, probably in the vicinity of the point
where the wall bends further to the west, could be chosen as a sample point. The similar release
points along the wall could be handled under representative outfall status. They would not have
to be individually sampled, once that status is established. Regulations require Sunrock to apply
to the Division for representative outfall status by sending a letter of request for our review.
On 1/10/06 during a follow-up visit by DWQ, washdown from the asphalt plant was exiting
through an opening in the curbed section meant to protect the grate from industrial runoff. This
was brought to Mr. Birdsall's attention at the time for immediate corrective action.
Our detailed comments on the Stormwater manual are as follows (also see attached checklist):
Part 1I Section A(1)(a) requires a USGS map zoomed to an appropriate level to show
transportation routes and surface waters. Please add a colored line from your SW outfall to
where it eventually enters a named stream. Label the stream, if the map does not make that
clear. Add the latitude and longitude of the outfall where it leaves the property.
2. For Part 11 Section A(1)(d), the site map, please calculate and note the °Io impervious portion
of the site. Crushed stone areas are considered impervious, in addition to paved areas.
Clearly identify the SW outfall on the map, as well, assuming a decision is made to continue
its existence rather than funneling that water to the recycle cell area.
3. Part It Section A(1)(e) requires recording significant spills of any kind. This could not be
located in the manual. Each year the report should note and be initialed if no spills occurred.
4. Part If Section A(1)(f) asks for certification (best during a rain) that no process wastewaters
from either the asphalt or the concrete plant join with rainwater before exiting the SW outfall.
5. Admixture chemicals and fuel at the concrete facility were inside containment structures.
However, the admixture containment drain valve was open and had no lock. See Part II
Section A(2)(b). Improved employee training should help con-ect this.
6. A summary of BMPs was absent, Part 1.1 Section A(2)(c). Please describe in some detail how
the drum washout pit and settling cells are used, how large rains are handled, and how water
is recycled or reused. This narrative should describe every BMP throughout the plant.
Drum washouts take place in a pit surrounded on three sides by concrete blocks. It was not
clear to this observer whether water escaped through cracks between blocks or not. It would
appear that an overflow during heavy rains (or heavy use) would likely move into the water
recycle cells. Please describe in the manual how this BMP can be counted on to keep the

Sunrock 12DU CEl 12/22/05 Page 3 of 3
contents on the site. As observed above, much of this water travels downward through the
surface and to the stream outside the wall.
7. A separate Spill Prevention and Response Plan, in addition of the SPCC manual on file,
needs to be written. Describe how contaminated SW will be handled. Part II Section A(3).
8. A description of your preventative maintenance program (to avoid broken hydraulic oil lines.
for example) and general housekeeping should be added, Part 11 Section A(4).
9. The Division has not received annual analytical data since the Sunrock takeover from Blaloc.
In light of the discussion above, a sample point for process wastewater traveling from the
retaining wall should be established as one outfall. The outfall that has so far been
considered the Stormwater outfall is to be sampled annually as a process wastewater- as well,
because of the high load of silt washed down the asphalt drive and from the aggregate piles
nearby. See the permit for details about parameters to be tested at these two outfalls.
A follow-up visit will be made in March to see the above revisions to the SP3 manual. Please
submit a request for rescission of permit NCG160138 right away. Please also send a request for
representative outfall status for releases along the wall.
