The
weather of 2010 presented many difficulties for growers in accomplishing
their crop residue-burning goals. Weather conditions throughout the state
in the late spring and early summer were cooler and wetter than normal,
which delayed the growing season. Many growers who would typically be
ready to burn by August, were not ready to burn until September or
October. Furthermore, August rainfall delayed crop residue burning for
some growers who were ready to burn in August. These factors pushed many
of the requests to burn into September and October,
when the days became shorter, temperatures became lower, mixing heights
and dispersion decreased, and precipitation became more likely. The full 2010 Crop Residue Burning Report can be accessed by clicking on the link below: http://www.deq.idaho.gov/air/prog_issues/burning/crop_residue_disposal_annual_report_2010.pdf
DEQ
issued a final burn approval on 58 days in at least one county in the
Central BMA during 2010, an increase from 56 days in 2009 and 32 days in
2008. Crop residue burning in 2010 was limited
by a late start to the growing season, persistent poor atmospheric
dispersion during the fall burn season and frequent precipitation events. burn
