NPDES Stormwater General Permit-NCG140000
Wake County
Mr. Hartley:
On October 4, 2019, Thad Valentine and Natalie Norberg from the Raleigh Regional Office of the Division
of Energy, Mineral, and Land Resources, conducted a site inspection for the Thomas Concrete of.
Carolina, Inc. facility located at 220 International Drive, Morrisville, Wake County, North Carolina. A copy
of the Compliance Inspection Report is enclosed for your review. Sherwood Turner, the Operations
Manager of that facility and Lily Walker, with Duncklee & Dunham, were also present during the
inspection and their time and assistance is greatly appreciated. Permit coverage authorizes the discharge
of stormwater from the facility to receiving waters designated as an unnamed tributary to receiving waters
designated as Crabtree Creek, a Class B;NSW waterbody in the Neuse River Basin. The site visit and file
review revealed that the subject facility is covered by NPDES Stormwater General Permit-NCG140000
Certificate of Coverage-NCG140266.
As a result of the site inspection, the following permit conditions violations are noted:
1) Stormwater Pollution Prevention Plan (SPPP)
A Stormwater Pollution Prevention Plan (SPPP) has not been developed, recorded, or properly
implemented. The site map should be revised to include any new sample points, if required, after a
thorough investigation of flow patterns, and the location of all pipe outfalls should be shown.
Provide an inspection and maintenance schedule that focuses on regular, daily cleaning of the facility with
emphasis on the loading area.
Repair the secondary containment area so it's watertight and be sure it's sized appropriately for the tanks
being held. Cleanup and store properly or remove all containers, tanks, and drums.

Inspection Summary.
Outfalls and outfall inspections:
The flow patterns for sample point for SDO-3 has not been fully investigated. There is an adjacent curb inlet that may or may
not flow to the outfall for SDO-3. Regardless, sampling at the curb inlet does not capture any runoff other than what flows
aboveground to the inlet. All of the pipe outlets must be identified and a dye test, or equivalent, should be performed to
identify all flow patterns and the outfall location of all drainage areas. Submit a summery of results once completed.
The entire facility will need to be cleaned. This includes any trash piles, any containers left out that should be sheltered form
stormwater and in general the entire site should be swept and cleaned of all concrete residuals and residue at regular
intervals and completely at least once a year. The loading area should be cleaned during the day and thouroughly at the end
of each day. The excess concrete stockplie should be located in an area that doesn't flood into the water treatment area of
the facility.
The water treatment basin is undersized and has caused overtopping during rain events that are causing offsite product and
probable water qualtiy standard violations in the adjacent creek. The basin will need to be resized and expanded to
accomadate the runoff from the site. Any and all containers (found around the site some open), drums and tanks (Poly tanks
not in use) need to be securely sealed and located under cover or in the secondary containment area
The secondary containment area needs to be sized for the tanks located within it and sealed with an expoxy on the inside
due to the crackes in the cinder blockes.
It is a requirement to contact DWR when there is a spill or discharge from a site (overtopping of the treatment area in this
case) that reaches and impacts a water body. Please make that notification and request a stream determination

Comment: The SP3 Dian appears to be in oreder except for a few chanoes that should be made. Provide on
the site map an updated flow pattern showing above ground and below ground flows that
discharge at one of the outfalls. Depending on the results of the flow patterns investigation (dye
test)and the outfall locations determined by finding the end off all the outfall pipes, additional site
map updates may be needed. Please document all spills in the SP3. If no spills occur during the
year document that there have been no spills during the year. Maintain the documents for the
required 3 years. Include in the BMP summery any additonal information that the flow pattern and
outfall locations investigation may provide. The documents for the preventive maintenance and
good housekeeping are in the SP3 but form our site walk it's obvious that the employees need to

From: Myrl Nisely
Subject: Recoil ofThomas Concrete Morrisville Plant for Stormwater Status, 10/29/04
Morrisville, NC
NCG 140266
Wake County
Prior to a visit to RRO by F&R consultant Bill Rice to discuss the West St. plant, this
visit was made to Morrisville to see whether compliance with NCG 14 had been
accomplished at this plant since the enforcement procedure for West St in January 2004.
Our records show no analytical data for this site over many years, so this visit was also a
check on whether any sampling had been done in 2004.
Unfortunately, nothing has been done. There is no SP3 manual and Manager Tim Brown
did not what it was or where to try to find it. I reviewed with him the inspection
checklist to give him some idea of what the manual would contain and his obligations for
employee training, qualitative observations and sampling. We then toured the portion of
the plant around the recycle system.
The site is virtually 100% impervious. SW drain points along the perimeter showed
evidence of concrete silt running to those location. A BMP improvement is needed there.
The recycle system appeared to be adequate, but removal of solids results in piling them
Lip against a handrail on one side with overflow right back into the recycle pit. R1111o1T
from the pile heads toward another SW drain, too. While standing there and looking over
the hill to a small retention pond full of solids, water began [lowing to the pond. A
worker behind us was hosing down the slab into the drain, and this was carrying heavy
concrete silt into the pond. The pond then overflowed into the wetlands. Many BMP
improvements are needed at this facility.
If F&R determines that they have a contract for improving all Thomas sites, I will work
with Mr. Rice to improve this location next. A decision on possible enforcement is
pending.
Update I1/17/04
Mr. Rice does have a contract to establish a program for each Thomas site. We walked
this location (and Angier Rd.) during which he noted areas for BMPs. I requested that he
calculate the volume for a 25 yr/ 24 hr storm and estimate the impact on the site. We
discussed what the maps should include. There appeared to be a rubber hose drain on the
admixture secondary containment. It was not clear whether it actually drains the
structutre or not. If so, it will need to be a hard pipe with valve and loci: or take the

0
handle off. If they choose to have no drain, that is also an option. I alerted him to the
fact that if there is a discharge point to which the Plow from the garage area goes, O&G
sampling will be required if the garage uses >55 gallons of motor oil per month average.
A SP3 manual exists for the West St. facility, so he will use that as it starting point for the
other sites.
Rice sounded as though only the West St. location will receive it significant overhaul —
i.e. there are no plans to put in wet mix technology at any of the other sites.

Dear Mr. Schuster: e
After thorough investigation, I would like to respond to your letter dated January 28, 2000 ( copy enclosed-)
regarding unlawful discharges into Pigeon House Creek. 'I'his response will include the cause of the violation and
our plan to prevent future discharges.
1. The cause of the discharge noted in item one (1) of your letter is a design flaw made by us when we paved our
yard last spring. We failed to install a curb on the north end of the property which will route surface waters
( including storm water ) back into our clarifying recycle system. "this additional curb is in the process ofbeing
installed now and should be complete by March 1, 2000,
2. "I'he discharge noted in item two (2) has been the result of two (2) main problems.
A. Our industry has slowed down dramatically since December 1, 1999. This slowdown in production
is due mainly from bad weather in December and the holiday season. When we have a reduction in
production, we also accumulate more waste water because we cannot recycle as hutch back into
our product. "this being the case, our recycle water pond must have overflowed.
I would also like to note that if this were a consistent problem, there would be a residue, of build-up
in the creek, which there is not.
B. The second factor leading to our recycle pond exceeding it's capacity is we are running about
one-third more trucks at this location than we feel the facility can efficiently handle. The reason for
this is we have been waiting to open a new facility in Wake Forest, but with weather delays, we are
behind schedule. This facility should open by March 1, 2000 and take a large load off of our
downtown plant.
Also, in the event of a siormwater overflow from this pond, we are putting large amounts of sand
around it for filtration of the cementitious material, which of course raises the pH levels.
'rhank you for your letter. We are addressing these issues immediately and educating our plant personnel on the
importance of this. If more information is needed or if you have any suggestions other than what we think will
solve this, please let me know
"thank you.

Dear Mr. Holding:
On January 7, 2000, Kent Penny of the Wake County Dept. of Environmental
Services investigated a citizens complaint about a discharge of cement laden water
flowing into Pigeon House Creek via a city stonndrain at 1131 N. West St. in Raleigh.
At that time it was evident that such a discharge has been ongoing as well as other
