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 May 13,2020, I, Richard Morris with NC Air Quality, called and spoke with Thomas Ledford who is the Facility Contact for Southern Concrete Materials Inc. —Ranger. No site visit was made due to the Covid-19 stay-in-place order. I asked to conduct a Partial Compliance Evaluation which is not an onsite visit. Mr. Thompson is the Western Area Division Manager and told me that this plant has not operated since my last visit on July 30, 2019. He informed me 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 hatching 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 hatching 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. Inspection: Plant not operating. 3) Emission Source and Regulatory Review: Sources are: (from last permit) _..... --- -- -- ------_. _._. .. ....
