(2) There are 87 facilities within Cabarrus County that are required to report quantities of chemical substances that the EPA has determined are hazardous. Of these facilities, 13 store or handle compounds that the EPA designates Extremely Hazardous Substances (EHS). These facilities employ one or more of thirteen individual Extremely Hazardous Substances. The most common EHS in the county are anhydrous ammonia., used in commercial coolant systems, and sulfuric acid, generally found in batteries. (f) Hazard Mitigation. (1) Current zoning ordinances and construction codes control the location and type of facilities that employ hazardous materials. Older facilities in the county, such as textile mills, are located closer to populated areas than the newer construction, which could cause problems in these areas. All of these facilities must meet storage requirements as established by the EPA. (2) The county and municipalities are improving response capabilities within their public safety agencies. The Concord Fire Department has developed a hazardous response team, similar to the regional response teams organized by the State of North Carolina. Additionally, the county and municipalities have organized a Special Hazards Response Team to react to a variety of hazardous materials incidents. 2. McGuire Nuclear Power Station (a) This facility is located at the southern end of Lake Norman in Mecklenburg County. Cabarrus County falls within the Emergency Planning Zone (EPZ) of the McGuire facility. This area has a radius of about 50 miles around the nuclear facility and is divided into two zones. The first zone is a 10 -mile Plume Exposure Pathway, in which the bulk of exposure to radiation or ingestion of radiological contaminants would occur. The county lies just outside the eastern side of this zone. The other zone, which includes the 10 -mile EPZ, is a 50 -mile Ingestion Exposure EPZ. The 50- mile EPZ is based on a number of considerations. One of those is that the downwind range, potentially threatened by contamination, would generally be limited to about 50 -miles or less from the power plant because of wind shifts, wind speed during the release, and radioactive decay. Another is that the particulate material from a radioactive plume would have been deposited on the ground within 50 miles of the facility. (b) Hazard Vulnerability. The US Department of Energy (DOE) and the Nuclear Regulatory Commission (NRC) require safety analysis for nuclear facilities. The United States requires extensive reviews of design and safety to ensure the safety of workers and the public. Even if an accident were to occur within the plant, regulators require that facilities be designed to withstand the damage, and thus eliminating secondary effects on the public. Therefore, due to the extensive regulations and safety measures, there is a very limited chance of a nuclear plant accident that would seriously affect Cabarrus County.
