not warmer than the surface temperature by more than 13 degrees
Fahrenheit.
(2) The expected
daytime temperature at 3,000 feet above the surface is colder than the expected
surface temperature by at least 11 degrees Fahrenheit for 4 hours.
(3) The expected daytime wind speed at 3,000
feet above the surface is at least 5 miles per hour.
(c) The South Section of this basin includes
Madera, Fresno, Kings, and Tulare Counties, and the San Joaquin Valley Air
Basin portion of Kern County.
(d) A
permissive-burn day will be declared in the South Section when the following
criteria are met:
(1) Above 3,000 feet
msl
*:
(A) Near 4:00
a.m., the mean 500 mb height over the Basin is less than the limiting mean
height given in Table 2 of section
80320.
(B) The expected 4:00 p.m. mean 500 mb height
over the Basin is less than the limiting mean height given in Table 2 of
section
80320.
(2) Below 3,000 feet
msl
*:
(A) Near the
time of day when the surface temperature is at a minimum, the temperature at
3,000 feet above the surface is not warmer than the surface temperature by more
than 13 degrees Fahrenheit.
(B) The
expected daytime temperature at 3,000 feet above the surface is colder than the
expected surface temperature by at least 11 degrees Fahrenheit for 4
hours.
(C) The expected daytime
wind speed at 3,000 feet above the surface is at least 5 miles per
hour.
(e)
Special situations in the Basin are:
(1) If,
when a no-burn day decision is declared, the state ambient air quality standard
for ozone, carbon monoxide, suspended particulate matter (PM10) or visibility
is expected to be exceeded during the valid period, a note to this effect shall
be appended to the announcement.
(2) A permissive-burn or no-burn day decision
that has been announced may be changed by the Air Resources Board at any time
prior to 10:00 a.m. if the meteorological and air quality situation that
actually unfolds so warrants it.
(3) A conditional permissive-burn day may be
declared in the North Section of the Air Basin during the months of November
through February for the burning of almond and walnut prunings (from not more
than 300 acres of orchard in each county) following three or more consecutive
no-burn days, provided that two of the three criteria set forth in section
80260(b) for
permissive-burn days are met, and provided further that the state board
determines that under expected meteorological conditions the burning of such
prunings will not have an adverse effect on air quality.
