field sanitizing purposes or with any other certified alternative
method to open field burning, propane flaming or stack or pile
burning. The fee required by paragraph (b) of this subsection
shall not be charged for any acreage not harvested prior to
burning or for any acreage not burned.
  (2) All fees collected under this section shall be deposited in
the State Treasury to the credit of the Department of Agriculture
Service Fund. Such moneys are continuously appropriated to the
State Department of Agriculture for the purpose of carrying out
the duties and responsibilities carried out by the State
Department of Agriculture pursuant to the memorandum of
understanding established under ORS 468A.585.
  (3) It is the intention of the Legislative Assembly that the
programs for smoke management, air quality monitoring and the
enforcement of rules under ORS 468A.550 to 468A.620 and 468A.992
be operated in a manner that maximizes the resources available
for the research and development program. Therefore, with regard
to the disbursement of funds collected under subsection (1) of
this section, the State Department of Agriculture shall act in
accordance with the intent of the Legislative Assembly and shall:
  (a) Pay an amount to the county or board of county
commissioners or the fire chief of the rural fire protection
district or other responsible person, for each fire protection
district, $1 per acre registered for each of the first 5,000
acres registered for open field burning and propane flaming in
the district, 75 cents per acre registered for each of the second
5,000 acres registered in the district and 35 cents per acre
registered for all acreage registered in the district in excess
of 10,000 acres, to cover the cost of and to be used solely for
the purpose of administering the program of registration of
acreage to be burned, issuance of permits, keeping of records and
other matters directly related to agricultural  { + open + }
field burning. For each acre from which straw is removed and
burned in stacks or piles, the State Department of Agriculture
shall pay to the county or board of county commissioners, or the
fire chief of the rural fire protection district or other
responsible person, 25 cents per acre.
  (b) Designate an amount to be used for the smoke management
program. The State Department of Agriculture by contract with the
Oregon Seed Council or otherwise shall organize rural fire
protection districts and growers, coordinate and provide
communications, hire ground support personnel, provide aircraft
surveillance and provide such added support services as are
necessary.
  (c) Retain funds for the operation and maintenance of the
Willamette Valley  { + open + } field burning air quality impact
monitoring network and to insure adequate enforcement of rules
established by the Environmental Quality Commission governing
standards of practice for open field burning, propane flaming and
stack or pile burning.
  (d) Of the remaining funds, designate an amount to be used for
additional funding for research and development proposals
described in the plan developed pursuant to section 15, chapter
920, Oregon Laws 1991.
  SECTION 12. ORS 468A.620 is amended to read:
  468A.620. (1) Notwithstanding the provisions of ORS 468A.610,
for the purpose of improving by demonstration or investigation
the environmental or agronomic effects of alternative methods of
field sanitization, the Environmental Quality Commission shall by
rule allow experimental field sanitization under the direction of
the Department of Environmental Quality for up to 1,000 acres of
perennial grass seed crops, annual grass seed crops and grain
crops in such areas and for such periods of time as it considers
necessary. Experimental field sanitization includes but is not
limited to:
  (a) Development, demonstration or training personnel in the use
of special or unusual field ignition techniques or methodologies.
  (b) Setting aside times, days or areas for special studies.
  (c) Operation of experimental mobile field sanitizers and
improved propane flaming devices.
  (d) Improved methods of stack or pile burning.
  (2) The commission may allow open  { + field + } burning under
this section of acreage for which permits have not been issued

  (a) Can, in theory, reduce the adverse effects on air quality
or public health from open field burning; and
  (b) Is necessary in order to obtain information on air quality,
public health or the agronomic effects of an experimental form of
field sanitization.
