We supply our export customers through Gulf Coast ports and coal terminals at Norfolk and Newport News, Virginia. Focusing on Reserves To fully serve our growing markets today and into the future, Massey Energy is acquiring reserves faster than we are mining them. Today more than 80 percent of our production is mined from reserves acquired since 1987. Over the last decade, we have invested heavily in exploring, evaluating, and acquiring high quality metallurgical and steam coal reserves. Currently, we control over two billion tons of coal reserves in southern West Virginia, eastern Kentucky, southwest Virginia, and Tennessee.
Program is second to none in the industry.
We have established safety standards that exceed federal and state requirements and implemented innovative safety initiatives at all our operations. Our S-1 program provides for ongoing reviews of all aspects of coal mining and processing. Every Massey Energy operation must pass rigorous safety audits and maintain a vigorous safety culture to achieve the prestigious S-1 certification. We rate ourselves against the toughest safety standards in the industry, and we work with manufacturers and suppliers to engineer safety into the equipment, gear, and tools our miners use every day on the job. Massey Energy's safety culture reflects our commitment to the well being of all our team members.
