3. Physical location information:
The facility is located at the site of the I-26 Buncombe County lane addition project south of the I-40/I-240 & I-26
interchange southwest of Asheville, NC.
Driving directions to the site:
From I401US 25 Interchange 50 in Asheville, NC, proceed 3.7 miles west on Interstate 40 to Exit 47 (NC 19-
Brevard Road) toward W Asheville/Farmers Market. Turn left at the intersection and proceed south onto NC
191-Brevard Road. Continue 0.6 mile south on NC 19- Brevard Road. Turn right onto Pond Road. Proceed 0.6
mile to address 118 Pond Road on left. Turn left into Henson's Inc. Mulch & More, and proceed downhill to the
back of the property and follow the road to the single -lane concrete bridge across Hominy Creek (about 500 ft).
Continue southward and uphill on the dirt road approximately 900 feet, passing the primary contractor's job
trailers on the left. Continue south and uphill an additional 400 feet to the site entrance for the concrete batch
plant.
8. Description of Industrial Activities
This batch plant will provide concrete for the paving of the I-26 Buncombe County lane addition project south of
the I40/I-240 & I-26 interchange southwest of Asheville, NC.
This facility will manufacture concrete, which is transported by dump truck to the area where lanes are being
paved. The primary components of the facility include the production plant, aboveground storage tanks that
contain diesel fuel and concrete admixtures, storage trailers and a silo that contain cement, as well as sand and
aggregate stored in open stockpiles. The manufacturing process requires moving aggregate and sand from
stockpiles to the processing plant using front-end loaders and conveyors. Cement is pneumatically added to the
sand and aggregate and processed in the mixing drum with water. The concrete is then loaded into dump trucks
for delivery to the paving project.
12. Type of Wastewater
A combination of wastewater and stormwater will be discharged from this facility's outfalls intermittently during
the approximately 6 months the plant is expected to operate at this site. Wastewater from the truck bed and drum
washout will be comingled with stormwater only when the plant is in operation. On the days the plant is
operating, the wastewater described in Attachment B will be generated.
17. Wastewater Treatment Alternatives Review
(b) This facility will be operated at this site for approximately six (6) months. Because of the cost involved
and potential delays to the NCDOT project as a result of permitting and construction required to temporarily
direct the wastewater from the identified sources to the sewer system, this option is not considered feasible for the
short period of time the plant will operate at this location.
(c) Surface or Subsurface Disposal Systems
(i) It is technically possible to use the recycled water from the truck bed washout recycling system for
dust suppression. It is also possible to treat and dispose of wastewater from the site through the existing
sediment basin adjacent to the site that was installed as part of the highway construction project.

(ii) It is possible to use the recycled water from the truck bed washout recycling system for dust
suppression as well as for re -use in the washout system.
(iii) These methods of surface disposal and re -use are feasible and will be implemented.
18. Best Management Practices (BMP)T.
(1) Riprap protection has been installed around all catch basins Vvrthin the plant site.
(2) A sediment basin with baffles and skimmer, and riprap inlet protection at all catch basins above slope drains
installed for the highway construction in and around the plant industrial site will be maintained during the
period the plant operates at this site.
(3) All areas within the plant site that were previously disturbed as part of the highway construction will be
stabilized with 4 to 6 inches of graded aggregate base (GAB) or vegetated with permanent vegetation.
(4) All parts and maintenance oil, grease, and fluids will be stored in closed containers inside the parts trailer or
inside the double -walled used -oil container at all times.
(5) Diesel fuel kept on site to fuel material handling equipment will be stored in a 1,000 gallon double -wall tank
inside of a portable containment dike.
(6) The double -wall steel diesel storage tank used to store fuel for the generator is located inside the generator
trailer.
(7) Regular inspections of potential sources of pollution are conducted.
24. Discharging wastewater to a BMP
The operation of this facility is a NCDOT project and will be discharging to an existing sediment basin.

NCG140000 N.O.I. Additional Information for Questions
McCarthy Improvement Company, Inc.
McCarthy Buncombe County Concrete Batch Plant
Description of Processes Producing Wastewater
Three processes at this facility will potentially contribute wastewater to the effluent from the outfall.
Wastewater Source 1:
Wastewater Source 1 is the concrete batch plant mixing drum. The drum on the plant will be washed out once per
day, on days the plant is operating. The wastewater produced from each washout is approximately 800 gallons
per day. This wastewater is captured in the upturned bucket of a front end loader and transported to the closest
truck bed washout recycling pit located on the site, where it is discharged from the bucket.
Wastewater Source 2:
Wastewater Source 2 is the truck bed washout used to washout the beds of the dump trucks used to transport the
concrete to the area being paved. The plant anticipates producing a maximum of 80 truckloads per day and the
trucks will be washed out after every second trip. Each washout will use approximately 50 gallons of water. The
anticipated volume of wash water generated will be approximately 2,000 gallons per day. The wash water will be
contained and recycled through a series of three settling pits designed to allow suspended particles to settle out of
the wash water. The dimensions of each pit will be 30 feet by 30 feet by 8 feet deep. The combined holding
capacity of the pits is approximately 160,000 gallons. The water in the third pit will be recycled as wash water or
used for dust suppression on the site. Solids will be removed from each pit when the volume occupied by the
solids equals one half of the designed holding capacity of the pit. The solids are allowed to dry and are properly
disposed of. If wash water is spilled or leaks from the recycling system or the washout area, it would flow to a
sediment basin adjacent to the washout pits, and from there would travel to a drop inlet already installed for the
highway being constructed. From here, it would ultimately be discharged via a sedimentation pond/skimmer
system, then overland approximately 600 feet to an unnamed tributary to Hominy Creek. A minimum fifteen
inches of freeboard will be maintained in the third washout pit at all times to accommodate a 10 year rain event
(3.7 inches) over the three ponds.
Wastewater Source 3:
Wastewater Source 3 includes the aggregate stockpiles. The aggregate stockpiles will be wetted using a lawn
sprinkler and hose. The sprinkler will be rotated around each stockpile during the day to cover all parts of each
pile. Wetting the aggregate stockpiles is done to produce evaporative cooling of the stone. The evaporation of
the water during this sprinkling process reduces the volume of water that ultimately flows away from the
stockpiles. Wetting is not used on the sand stockpile. Per DOT specifications, both the aggregate and sand are
washed prior to being delivered to the site, reducing the potential fines in stormwater runoff from the area covered
by the stockpiles. Wetting of the aggregate stockpile will be conducted up to 24 hours per day when the plant is
operating during summer months. The wastewater from the aggregate stockpile will consist of water from the
wetting of the stone and stormwater that falls on the pile. Wastewater from the sand stockpile will consist of only
stormwater that falls on the pile. Stormwater and wastewater from the stockpiles will flow to a sedimentation
pond/skimmer system, then overland approximately 600 feet to an unnamed tributary to Hominy Creek.
