The Agency for Toxic Substances and Disease Registry (ATSDR) is a federal public health agency within the United States Department of Health and Human Services. The agency focuses on minimizing human health risks associated with exposure to hazardous substances. It works closely with other federal, state, and local agencies; tribal governments; local communities; and healthcare providers. Its mission is to "Serve the public through responsive public health actions to promote healthy and safe environments and prevent harmful exposures." ATSDR was created as an advisory, nonregulatory agency by the Superfund legislation and was formally organized in 1985. Although ATSDR is an independent operating agency within the Department of Health and Human Services, the Centers for Disease Control and Prevention (CDC) performs many of its administrative functions. The CDC director also serves as the ATSDR administrator, and ATSDR has a joint Office of the Director with the National Center for Environmental Health (NCEH). The ATSDR headquarters are located in Atlanta, Georgia, at the CDC Chamblee campus. In fiscal year 2010, ATSDR had an operating budget of $76.8 million and had roughly 300 full-time employees (not including contractors). ATSDR is formally and administratively overseen by the director of the Centers for Disease Control and Prevention (CDC), currently Dr. Rochelle Walensky, in their capacity as ATSDR Administrator. Direction is provided by ATSDR's director, currently Dr. Patrick Breysse, who ranks below the Administrator, and ATSDR's associate director, currently Dr. Christopher Reh. From Wikipedia
