Of the 55 STAPPA agencies, 48 (87%) responded to the questionnaire; of the 170 ALAPCO
agencies, 149 (88%) responded (overall response rate: 88%).
According to STAPPA and ALAPCO, the report details the results of an analysis conducted using EPA methodology for calculating health impacts to quantify the adverse health effects associated with locomotive and marine diesel emissions.
STAPPA and ALAPCO noted that they have transmitted the report to EPA administrator Stephen Johnson, urging the agency to propose and finalize standards to reduce emissions from locomotive and marine diesel engines by at least 90 percent, with full implementation in effect by 2011.
The State and Territorial Air Pollution Program Administrators (STAPPA) and the Association of Local Air Pollution Control Officials (ALAPCO
) recently announced they have sent a letter to Environmental Protection Agency (EPA) assistant administrator Jeffrey Holmstead and Federal Aviation Administration (FAA) assistant administrator Sharon Pinkerton to formally notify them of the associations' decision to withdraw from the EPA/FAA stakeholder process to develop a voluntary emission reduction program for the aviation sector.
