On April 16, 2015 the USDA Agricultural Air Quality Task Force was re-established for 2 years (until April 16, 2017).  The new AAQTF Charter is posted here. This confirms the commitment of the Department and the NRCS to continue the important work of the AAQTF since it was established in the 1996 Federal Agriculture Improvement and Reform Act. The AAQTF is the only Federal Advisory Committee under the direction of the NRCS and is chaired by Chief Jason Weller. The solicitation for nominations for the new AAQTF will occur in the near future. Presently, there are 28 members of the Task Force, and their terms will end on July 15 (see 2013 announcement of current members here). Anyone with interest in agricultural air quality is welcomed to apply.

Task Force Mission


Gavel Gavel

The Agricultural Air Quality Task Force has been created in accordance with Section 391 of the Federal Agriculture Improvement and Reform (FAIR) Act of 1996, which directs the Chief of the Natural Resources Conservation Service (NRCS), an agency of the United States Department of Agriculture, to establish a task force to address agricultural air quality issues.

The Agricultural Air Quality Task Force (AAQTF) was established to comply with Congress and consists of leaders in farming, industry, health, and science. In 1996, Congress found that various studies have alleged that agriculture is a source of PM10 emissions and that many of these studies have often been based on erroneous data. Congress also cited ongoing research by the Department of Agriculture and that federal policy, in regard to air pollution, be based on sound scientific findings that are subject to adequate peer review and take into account economic feasibility. The Secretary of Agriculture was charged to ensure that Departmental federal air quality research not report erroneous data.
