Re: Notice of Intent Submittal for Coverage under NCG140000
Proposed Blue Dot Ready -Mix, LLC (Ready Mixed) Concrete Plant Facility
10500 Old Nations Ford Road
Pineville, Mecklenburg County, NC
To Whom It May Concern:
Enclosed please find the materials identified below as a Notice of Intent (NOI) application for a
proposed ready mixed concrete plant to be constructed and operated at the location identified
above. Please note that this proposed facility is in the final stages of securing local approval,
anticipates commencement of construction activities shortly, and also anticipates commenced of
operations with the near future. This plant is presently not constructed or operating.
Since this concrete plant is not constructed or operating, this NOI and supporting materials are
submitted at this time based on presumed operations at the plant relative to the discharge of
stormwater and process wastewater, based on current site plans and similar operations of Blue
Dot located elsewhere. Therefore, it is noted that permit coverage issued to this facility may be
the subject of modification in the future upon commencement of operations (e.g., the possible
removal of process wastewater discharge outfalls, or the request for representative outfalls),
however this will be made at a later time — as/if necessary — after operations have commenced. In
the meantime, the operations described by this NOI application represent a conservative, "worst
case" operating scenario for this plant.
The location of the proposed concrete plant facility is presently a large vacant property, directly
adjacent to an existing aggregate quarry (Vulcan Materials) which used to house a hot -mix asphalt
plant and ancillary facilities (which moved to the other side of Old Nations Ford Rd). The site is
graded and cleared from this past use and is located directly adjacent to 1-485 (see site location
below). Nearby properties include the aforementioned quarry, the aforementioned asphalt plant
(which moved from the subject property in the past across Old Nations Ford Road), and an
equipment rental facility.

Previous site activities at this location, via past site grading, resulted in drainage at the site to the
southwest in the direction of 1-485. Site runoff then flows via overland flow into an existing
drainage pond located on the subject property, from whence drainage goes beneath 1-485 via
Re: Notice of Intent Submittal for Coverage under NCG140000

Pineville, Mecklenburg County, NC
Page 2 of 7

drainage structures to Sugar Creek south of I-485 (i.e., on the "other side' of 1-485). Therefore,
this site discharges to Sugar Creek.
The current site plan for this site, in its final stages of local approval, provide for 3 on -site discharge
points which drain into this one existing drainage pond. The drainage pond has one outfall "offsite"
to the 1-485 drainage system that ultimately leads to Sugar Creek (which might present the
opportunity for one discharge outfall from this site), however that drainage pond is also
anticipated to receive runoff from other, non -related business operations which may be located
on the adjacent property in the near future, which may commingle with that from the subject
property. Therefore, the 3 discharge points (shown on the enclosed materials) represent the most
accurate and representative discharge locations (at least at this point, from proposed site plans)
from the subject property; as such, the included NOI identifies 3 discharge points, identified on
the NO1 as outfalls 001, 002, 003. If this situation changes in the future based on actual site
conditions and operations, permit coverage will be requested for modification accordingly.
Site planning at this point is to utilize a concrete washout / process wastewater settling basin
system which is anticipated to contain the "working volume" along with entrained rainfall resulting
from a 25-year / 24-hour storm event (as a Closed -Loop Recycle System, or "CLRS"). This working
volume is to include direct drainage. However, since it is unclear if all non-stormwater generated
from this site (such as from aggregate watering) will be retained on -site or may be discharged, and
so for now —to provide a conservative approach at this time— we are identifying two of the three
outfalls (those within the "working area" of the plant as discharging both stormwater and process
wastewater.
As I have stated, we will reconsider this once the plant is complete and operational, modify permit
coverage as appropriate (with, of course, input from the applicable NCDEQ regional inspector),
and proceed accordingly. Given the design for the settling basin system at present, it is very
possible that we may pursue appropriate permitting at that time with the Department of Water
Resources for the CLRS.
The following materials are included herein:
1. Completed NO[ form;
2. Copy of most recent Annual Report to the NC Secretary of State showing current legal
name;
3. Site plans showingthe proposed facility, and which have the outfall locations identified (via
hand annotation), believed to be showing all required information, as prepared by Alley,
Williams, Carmen & King, Inc., Consulting Engineers, Kannapolis NC (NOTE: the enclosed
plans are those preliminarily generated for local approval, and may have been, or will be,
revised to reflect requirements of local approval);
4. A line drawing of water flow through the facility;
5. A general narrative description of the process to be used at this facility;
6. A check in the amount of $100.00 payable to NCDEQ;

Please note that this facility, as previously stated, is in the final stages of the local approval process
and is shortly to be issued approval related to construction activities, including covering erosion
and sediment control. When received, this approval will be forwarded in support of this
application.
I trust that you will find this information sufficient to begin review of this application leading to
permit coverage. Should you have any questions, or require any additional information, please do
not hesitate to contact me.

General Narrative of Operations
The proposed facility is a ready -mixed concrete plant, which produces concrete materials at the
subject property which are then transported, in concrete mixer trucks, to a variety of off -site
construction projects (public and private) located within the vicinity of the subject property. This
type of plant is identified as a "ready mixed" plant in that the concrete materials are stored and
mixed on site, then provided already mixed at the off-sitejobsite ("ready mixed"), instead of these
activities occurring at a jobsite (in far small quantities than can be provided by this type of plant).
The concrete plant to be covered by this permit is therefore fairly typical of other "ready mixed"
concrete plants, both in North Carolina and elsewhere in the United States.
Ready mixed concrete is made as follows:
• Materials needed for concrete production are delivered by off -site suppliers on an as -
needed basis to the plant location, including aggregate materials (sand and stone), cement
materials (Portland cement, slag, or fly -ash, etc.), strengthening materials (e.g., fiberglass
or steel fibers), concrete chemical admixtures, concrete coloring agents in solid or liquid
form, as well as any other materials required for plant operation. These materials are
delivered to, and stored at the concrete plant, as follows:
o Aggregate materials are delivered to the concrete plant via truck, coming from local
quarry sources. These materials are then stockpiled on the concrete plant site,
usually within (large) concrete block containment wall structures for easier
management. In general, these materials are exposed to rainfall, and, during hot
summer months, often require regular watering to reduce their temperatures to
working levels for concrete production. These materials, after storage in bin areas,
are regularly loaded throughout the work day via a front-end loader which places
buckets of sand and/or stone into the feed bin at the concrete plant, where it then
travels by conveyor belt to aggregate storage / weigh bins (the material is usually
withdrawn for production on the basis of a pre -determined weight of aggregate
needed for the desired end -product concrete batch), where it is stored until
needed. When it is needed, the appropriate amount of sand and stone is sent from
the storage bins / weigh bins to the mixing area of the plant (entirely enclosed),
where it is then dropped into the awaiting concrete mixer truck for mixing and off -
site delivery.
o Cement materials arrive at the site in contained tanker trucks, off-loaded using
pneumatic (air) delivery systems into enclosed containment silos, from whence
they are delivered directly into the concrete mixing portion of the concrete plant.
These materials are virtually never exposed to rainfall.
o Materials such as fiberglass fibers or steel fibers are normally shipped to the
concrete plant in cardboard boxes or similar small containers, stored indoors at the
plant until needed, then put into specific concrete batches as desired (depending

on the specific particular mix design being made) by hand, directly into the back of
a mixer truck during loading, or via a small screw conveyor into the materials mixing
chute that is going directly into the concrete mixer truck. These materials are not
exposed to stormwater. Solid concrete coloring agents (to provide coloration to
specific batches of concrete being made) are also handled in this manner, although
sometimes they may be stored in small storage silos from which they are conveyed
directly into the concrete being mixed during the mixing process.
o Concrete chemical admixtures, used to impart specific desired properties to the
concrete being produced, based on the chosen mix design and end use, and
delivered to the concrete plant in tanker truck, unloaded from the truck using hoses
into plastic admixture storage tanks where they are stored, then conveyed into the
concrete being mixed by a system of computer -controlled delivery hoses. These
materials are not exposed to stormwater and are anticipated to be located within
an area with secondary containment. Liquid coloring agents would also be handled
in the same manner.
o While no truck maintenance is proposed for this facility (it would occur at an off -
site truck maintenance facility owned by the applicant), light truck maintenance
(e.g., "topping off" truck engine oil, adding anti -freeze or windshield wiper fluid,
etc.) and plant maintenance activities would occur on this site, and may require the
delivery of maintenance products (oil, lubricants, etc.) in solid or liquid form, which
usually are delivered in small containers (55-gallon and smaller) to the plant, where
they are stored inside the plant or in a suitable storage area until needed for use.
These materials are not exposed to stormwater under normal circumstances, and
only relatively small amounts would be stored at the site.
• As stored at the concrete plant, raw materials (sand, stone, water, cement, chemical
admixtures, and any other material to be included such as color or fibers), are stored at
the plant as described above. When a specific batch of concrete is ordered (by a customer),
it is produced via a pre-programmed "mix design" (depending on the desired end use of
the concrete), which then starts the mixing process by delivering pre -determined amounts
of raw materials from their storage areas to the mixing area and then into trucks. This
normally includes a pre -determined weight of water needed for the mix design. All of these
materials are deposited through the plant's load point into the awaiting concrete mixer
truck, where they continue to mix as the truck finalizes preparation for delivery, and while
in transit to the specific jobsite location off -site.
• After loading at the concrete plant's load point, the concrete mixer trucks undergo a final
rinse with water to remove any residue present from the loading process, as well as any
potential residue present on the truck's delivery chute. At this plant, rather than simply
"hosing off" at a wash rack location, a "Load-N-Go" system will be used (a rinse system
similar to the final rinse at a commercial car wash) which rinses the truck and truck loading
area as it is passing away from the plant, towards the facility's exit. The rinse water from

this system — to be located directly adjacent to the on -site concrete washout / settling
basin (CLRS) — will drain directly into that system, for further clarification and reuse.
• After returning to the concrete plant, concrete mixer trucks will continue throughout the
day to get additional loads of concrete, batched specifically in accordance with a requested
mix design depending on the end use of the concrete by the customer. At the end of each
day, each concrete mixer truck which has made deliveries that day must undergo a truck
mixer barrel "washout" by rinsing the barrel interior to remove concrete residue inside (if
not, it would harden overnight inside the barrel), which is done by a truck backing up to
the water hose rack at the on -site concrete washout / settling basin (CLRS), putting water
into the mixer barrel which is then allowed to rinse (via agitation) the interior of the truck
mixer barrel by turning the mixer barrel for several minutes. The rinsewater is then poured
out the mixer barrel (down the truck's discharge chute) into the, on -site concrete washout
/ settling basin (CLRS), where it sequentially goes through the basin's weir -controlled cells,
allowing settling and filtration to occur; when the clarified water reaches the final cell in
the system, it is withdrawn (by small electric pump) back to the system's water hose rack
for further washout activities in a closed -loop, non -discharging manner (as proposed).
• Source materials exposed to rainfall at this site include sand and stone, the concrete plant
itself, enclosed storage containers for the materials previously described, on -site
equipment (such as a front-end loader), trucks both on -site (which may be parked) and off -
site (out for deliveries), paved drive lanes around the plant, and unpaved areas.
Stormwater runoff from these areas will flow towards the outfall locations described
herein, and eventually discharge off -site. Similarly, when operational, non-stormwater may
be discharged from this site, to include (buy may not be limited to) stockpile watering,
incidental pavement, etc.
