RE: Response to the NPDES Stormwater Compliance Evaluation Inspection, for Southern Equipment
Company dba Ready Mixed Concrete Co., Apex Plant #6, 1501 East Williams Street, Apex, NC, Wake
County; NCG14000 General Permit, COC # NCG140073.
This letter is in response to item #3 needing attention/comments on the inspection at our Apex facility,
COC #NCG 140073, on August 5, 2015. First of all, thank you for taking the time to perform this
inspection with our Operations Manager, Jay Watkins, and myself. Your inspection was thorough and
your comments and advice were well taken. I apologize for the delay in responding, but we have tried to
set up a time for our internal Environmental Manager and our outside Environmental Consultant to come
and visit the site to observe and confirm, but we were not able to set that up before the deadline for a
response. Here is the response to item #3 listed:
3. Starting in 2016, we plan to move SD02 to the new location that you noted on the inspection and
will start sampling for analytical monitoring at this location. This location is on the east half of
the facility and enters the receiving stream at the downstream culvert on the south side of the
unpaved road. We plan to eliminate the current SD02 at the southeast corner of the facility as an
SDO. We will note the location on our site map in handwriting. In early 2016, we plan to get our
Environmental Consultant and Environmental Manager to the plant to visually confirm they are in
approval. If they have any questions or concerns about the new SD02 site, we will get with you at
that time. If they do not, we will plan to get an updated site map completed to note the new
location.
Again, thank you for taking the time to inspect our facility and communicate your observations and
comments with us. Our plants are generally open based on daily production requirements.

Dear Mr. Walters:
Staff from the Department of Environmental and Natural Resources conducted a stormwater inspection
on August 5, 2015, as part of a multimedia inspection of your facility. The assistance provided by Mr.
Jay Watkins, Operations Manger, and you during the inspection was greatly appreciated. The inspection
report is attached. Findings during the inspection were as follows:
Certificate of Coverage (COC) No. NCG140073 under NPDES General Permit NCG140000
was issued to Ready Mixed Concrete — Apex Plant #6 to discharge stormwater runoff and
process wastewater to an unnamed tributary to Middle Creek, a Class C, NSW stream, in the
Neuse River Basin.
2. The facility has developed a stormwater pollution prevention plan (SPPP). A review of the
plan indicated that it included all of the components required by the general permit.
3. Semi-annual qualitative and analytical monitoring has been conducted as required by the
permit at the both stormwater discharge outfalls (SDOs). However, samples from SDO
2 were actually collected in stream at the southeast corner of the facility, where runoff
leaves the facility via sheet flow. Runoff from east half of the facility enters the receiving
stream near the downstream culvert on the south side of the unpaved road, this
stormwater entry point should be identified as a SDO, at which analytical monitoring
samples should be collected.
4. Both SDOs were observed during the inspection. SDO1 was maintained and accessible.

November 6, 2002
Subject: Notice of Violation
Apex Ready Mix Plant
NPDES Stormwater Permit NCG 149I3(
Apex, NC
Wake County
(/Uro'v
Itioa73 n1Gh
On October 10, 2002 Mn Myrl Nisely of the Raleigh Regional office of Division of Water Quality performed a coimpliance
inspection at the Apex facility. The helpful cooperation of Mr. Clavon Wiggins was greatly appreciated.
Overview
As noted at other Ready Mix locations, this program shows generally good attention to the SPPP documents required in the
pernut, but there are deficiencies in properly handling stormwater/process wastewater. Violations of the TSS limit at every
sampling point have occurred since at least 1999. Sampling practices will be discussed below. The SPPP manual
contained records that showed good program planning, inspections, monitoring, housekeeping and other details that
demonstrate implementation of the program. A few "tune-up" points for the SPPP manual are listed below. Physical
conditions at the plant still need modification to provide engineered Best Management Practices (BMPs) to control both
process water and stormwater as per the permit.
Details
The SPPP is very well done and contains forms for all the required elements. Most sections have data, but the following
changes still are needed:
The good detailed description of the site found in an early section needs to be updated. For instance, secondary
containment has been added, and other details will need to be revised, especially in light of changes requested below. A
page near the beginning of the manual declaring the dates of annual updates is needed, as well.
2. The USGS map for Part II Section A (l.)(a) lacks some detail requested by the Division. Please prepare a USG S-type
map "zoomed in" somewhat to show the facility's location in reference to transportation routes (as the present map does)
and the route of all stormwater discharges all the way to the receiving water(s). For example, where does the culvert
under Hwy 55 eventually go? Clearly identify the name(s) of receiving stream(s). Please send a copy of this map to the
Division.

Ready Mix Concrete, November 6, 2002 p. 2
3. Changes are requested on the plant site map, including sample point modifications from the discussion in point 4. below.
Please also send a copy of this map to the Division.
a) Please designate the approximate areas being served by each discharge point (Section A(1)(c). These areas are
apparently being used to calculate the total flow passing through each sample point during a sampling event.
b) Add the lot across the street from the office building. This is where vehicle and equipment cleaning takes place, so
show the runoff flow patter.
c) Show the new admixture chemical containment structure.
4. The Division wishes to make sure that control of process wastewater and stormwater is adequate to meet permit limits at
every discharge point:
a. The drum wash pit is being used as a detention basin. At present, water in this pit evaporates and may contribute to
impacts to groundwater. Therefore, any pit/containment structure should be built such that groundwater as well as
water quality standards are protected.
b. pH control must be assured to meet the 6 to 9 units specified in the permit at every discharge/sampling point. Limits
for TSS and settleable solids must likewise be met.
c. The lot across the gravel road shows potential for release of contaminated rainwater. This vehicle cleaning area must
be designed to provide sampling during a rain per Section C. Provide engineered structures for this part of the
property to fully control/treat the stormwater and process wastewater. At present some or all of this flow goes to
Middle creek on that side of the gravel road.
d. Sheet flow to Point #3 has no particular structural control and a small vegetative buffer before entering Middle
Creek. This vegetation is inadequate to reduce solids. Investigate methods for assuring removal of solids to less
than 30 mg/I in the flow to the creek.
5. Sampling methods being used are probably not providing analytical results representative of water quality that reaches
Point #3 Middle Creek, nor water quality from the Drum Wash Pit.
You may want to pursue installing a more permanent pit from which to collect samples, versus cutting a temporary
pit on the day of sampling.
Please respond in writing within 30 days of receipt of this letter. If you have any comments or questions, contact Myrl Nisely
at 919-571-4700.

information that is needed, to meet the1999 permit requirements. 1) Add the new
admixture containment structure; 2) Show each outfall and the square footage
serving each outfall. 3) Add the lot across the street to the site plan. 4)You also
asked for a page near the beginning of the SWPPP manual declaring dates of
annual updates, this page is the cover of our SWPPP at this site and at all
locations.
The second Statement was about a zoomed in USGS-type map. Our plan
includes a USGS map of the site. We have a narrative in our plan that provides
the information you have asked for. I have tried to blow up a USGS map to the
scale that you have asked for and the information that you asked for is still not
shown. I have included a copy for your review. The only way to give you the
information that you are asking for is to hand writes it on the USGS map.
The wash pit is going to be evaluated by Mid Atlantic. I will send you a copy of
the updated site plan and their recommendations for this wash pit once they are
completed. The lot across the street is only used to pour recycled concrete block
forms and for drivers to mix their loads on busy days. We will add this to our site
plan and start testing this water.
Discharge point # 1 will be removed from our site plan since it is sheet flow that is
filtered by 175' of vegetation.
