Advocates Raise Doubts Over SO2 Data Underpinning Major EPA Air Rules

摘要

Environmentalists are pursuing an Information Quality Act (IQA) challenge to EPA data on sulfur dioxide (SO2) emissions that underpins parts of several major air rules including its Cross-State Air Pollution Rule (CSAPR) and utility air toxics regulation, warning that recent agency statements might undermine data in those policies. In a Feb. 23 request for correction under the IQA filed with EPA, the Chesapeake Climate Action Network (CCAN) and Environmental Integrity Project (EIP) say that it is unclear whether the data at issue is accurate and reliable as required under the data law. They warn that the problems they believe exist with the data mean that at least some major air rules might be based on inaccurate data, which in turn could make those standards flawed.
