Mercury
Mercury is a naturally occurring element that is found in air, water, and soil. It exists in several forms –elemental (also known as metallic mercury), inorganic, and organic. Mercury is a liquid metal that easily evaporates, giving off invisible, odorless, and toxic vapors. Mercury cannot be created or destroyed., Mercury in the Environment, Mercury is released into the environment from many sources. Mercury becomes airborne when rocks erode, volcanoes erupt and soil decomposes. It then circulates in the atmosphere and is redistributed throughout the environment. Human activities, such as burning coal, oil, and natural gas as well as burning household trash and mining, add mercury to the environment. Once in the air, mercury falls to…, Learn more about mercury in the environment, ., Health Risks of Mercury Exposure, Mercury is toxic. Exposure to mercury – even in small amounts – may cause serious health problems. People can be exposed to mercury through skin contact, by eating contaminated fish, or by breathing mercury vapors., Learn more about the health risks of mercury, ., Mercury in the Home, While some manufacturers have reduced or eliminated the use of mercury in their products, there are still many products that we use every day in our homes that contain mercury. Some products are made with mercury added to perform a specific function. These products are called "mercury-added products." Other products may have small amounts of mercury in them because a chemical used in the…, Learn more about mercury in the home, .

Overview, As part of the air permitting process, facilities in South Carolina are required to demonstrate that the emissions coming from their sources will not cause the violation of any applicable South Carolina air pollution control regulations or standards. It is a required part of many air construction permits (including all Prevention of Significant Deterioration (PSD) construction permits) and some…, Who Needs to Use It?, An air dispersion model is a set of mathematical equations that relates the release of air pollutants from emission sources to the corresponding concentration of pollutants in the ambient air. These models are tools used to determine if the emissions from a source can meet a specific ambient air standard. Regulations may allow other approaches, but air dispersion modeling is typically the least…Chemical Manufacturing

If your facility emits Hazardous Air Pollutants (HAP), you are a major or an area source of HAP., Major Sources of HAPs (Maximum Achievable Control Technology (MACT), Major sources are medium to large industrial facilities that emit 10 tons per year of any of a single HAP, or 25 tons per year of a combination of HAPs. These sources may release HAPs from equipment leaks, when materials are transferred from one location to another, or during discharge through emission stacks or vents., Area Sources (Small HAP Sources), Area sources consist of smaller-size facilities that release lesser quantities of HAPs into the air. Area sources emit less than 10 tons per year of a single HAP, and less than 25 tons per year of a combination of HAPs. Though emissions from individual area sources are often relatively small, collectively their emissions can be of concern - particularly where large numbers of sources are located…, Reporting Forms, Ongoing Compliance Report, Subpart N Annual Certification and Compliance Report with Visible Emissions, Subpart 6X Annual Certification and Compliance Report without Visible Emissions, Subpart 6X, Important Links, EPA's Air Toxics Website EPA's Urban Air Toxics and Area Source Website NESHAP List in Alphabetical Order (EPA) Small Business Environmental Assistance Program RICE NESHAP Applicability Tool
