Compliance Assurance Visit Report:

1) Location: Southern Concrete Materials Inc. - Ranger is located at 395 Wingate Road
in Ranger,NC. Cherokee Co.
Directions: Take Hwy 19/74/129 from Murphy to Hwy 64/74 West to Ranger.
Follow 64 west for approximately 11 miles. The facility is located off of the Hwy
on the right.
2) Facility Overview: Southern Concrete Materials Inc. - Ranger is a concrete batch
plant, producing concrete for commercial use. This facility is permit exempt
effective August 5,2016. Last compliance inspection conducted on August 10, 2018
by Richard Morris
Safety: Steel toed shoes, eye protection
Current throughputs: Facility is not operating.
Pre-inspection Conference: On July 30, 2019, I, Richard Morris with NC Air
Quality arrived at Southern Concrete Materials Inc. —Ranger to conduct a compliance
assistance inspection. Upon arrival, I observed the facility is closed and has not
operated for some time. I spoke with Jeff Lamm about this facility and was informed
that this plant was used as a back-up for the Andrews Plant on the Cherokee Casino.
Very little production occurs at this plant. There are no plans to run this facility full
time in the near future.
Process Description: (AP-42)
Concrete is composed essentially of water, cement, sand (fine aggregate), and coarse
aggregate. Coarse aggregate may consist of gravel, crushed stone, or iron blast furnace
slag. Some specialty aggregate products could be either heavyweight aggregate (of
barite, magnetite, limonite, ilmenite, iron,or steel) or lightweight aggregate (with sintered
clay, shale, slate, diatomaceous shale,perlite, vermiculite, slag,pumice, cinders, or
sintered fly ash). Concrete batching plants store, convey, measure, and discharge these
constituents into trucks for transport to a job site. In some cases, concrete is prepared at a
building construction site or for the manufacture of concrete products such as pipes and
prefabricated construction parts. The raw materials can be delivered to a plant by rail,
truck, or barge. The cement is transferred to elevated storage silos pneumatically or by
bucket elevator. The sand and coarse aggregate are transferred to elevated bins by front
end loader, clam shell crane, belt conveyor, or bucket elevator. From these elevated bins,
the constituents are fed by gravity or screw conveyor to weigh hoppers, which combine
the proper amounts of each material. Truck mixed(transit mixed) concrete involves
approximately 75 percent of U. S. concrete batching plants. At these plants, sand,
aggregate, cement, and water are all gravity fed from the weigh hopper into the mixer
trucks. The concrete is mixed on the way to the site where the concrete is to be poured.
Central mix facilities (including shrink mixed) constitute the other one-fourth of the
industry. With these, concrete is mixed and then transferred to either an open bed dump
truck or an agitator truck for transport to the job site. Shrink mixed concrete is concrete
that is partially mixed at the central mix plant and then completely mixed in a truck mixer

on the way to the job site. Dry batching, with concrete mixed and hauled to the
construction site in dry form, is seldom, if ever, used.
