Seven months after being subpoenaed by Congress, Environmental Protection Agency (EPA) Administrator Gina McCarthy conceded that her agency does not have – and cannot produce – all of the scientific data used for decades to justify numerous rules and regulations under the Clean Air Act.
In a March 7th letter to House Science, Space and Technology Committee chairman Lamar Smith (R-Tex.), McCarthy admitted that EPA cannot produce all of the original data from the 1993 Harvard Six Cities Study (HSC) and the American Cancer Society’s (ACS) 1995 Cancer Prevention Study II, which is currently housed at New York University.
Both studies concluded that fine airborne particles measuring 2.5 micrograms or less (PM2.5) – 1/30th the diameter of a human hair – are killing thousands of Americans every year.
