Situated on over 5000 acres of timberland, Alcoa-Mt. Holly is a primary aluminum smelter that was constructed in 1980.  Mt Holly, an industry leader in production efficiency, energy utilization, and environmental control, was the first primary aluminum plant in the world to be registered totally to the ISO 9002 Quality System Standard.

The Mt. Holly facility represents an original capital investment of over $340 million dollars in the Lowcountry.  Alcoa-Mt. Holly has an annual capacity of 245,000 tons of aluminum. The Mt. Holly plant contributes more than $150,000,000 annually to the tri-county economy through payroll, taxes, and purchases of goods and services.  The direct jobs average more than $75,000 in wages and benefits for a $47,000,000 annual payroll.  A conservative multiplier would add another 1,200 indirect jobs with a $20,000,000 impact on the local economy through jobs associated with retail businesses and services.  Mt Holly paid $2.5 million in state and local taxes, two-thirds of which are property taxes that go to the county for investment in our local school system.
