Or. Admin. R. 629-048-0110 - Characterization and Response to Smoke Incidents, Smoke Intrusions, and National Ambient Air Quality Standards (NAAQS) Exceedances
(1)
(a)
When investigating or collecting information on smoke incidents or smoke
intrusions, the department will attempt to characterize the impact as either a
smoke intrusion or a smoke incident as defined in OAR 629-048-0005.
(b) As used in the Smoke Management rules,
"smoke intrusion" refers only to ground level prescribed burning smoke that
enters an SSRA at particulate matter values defined in OAR
629-048-0005(27).
(2)
When measurements or observations are available, smoke incidents or smoke
intrusions are characterized based on particulate matter values over a one-hour
average period, or a 24-hour average period from midnight to
midnight.
(3) When no particulate
matter dataareavailable, smoke incidents or smoke intrusions are determined
based on reduction in visibility averaged over a one-hour period using standard
National Weather Service visibility observation criteria (Federal
Meteorological Handbook No. 1) and a table of reductions keyed tovarious
background visibility levels as displayed in Department Directive 1-4-1-601,
"Operational Guidance for the Oregon Smoke Management Program."
(4) Smoke incidents andsmoke intrusions will
be documented and used to assess annual program performance. Department
Directive 1-4-1-601 "Operational Guidance for the Oregon Smoke Management
Program" will describe applicable reporting requirements and actions to be
taken.
(5) Smoke intrusions
thataverage at or abovethe 24-hour average PM2.5 value of 35 microgram per
cubic meter (NAAQS exceedance) will be reported to DEQ as soon as possible.
Department Directive 1-4-1-601 "Operational Guidance for the Oregon Smoke
Management Program" will describe applicable reporting requirements and
adaptive management actions to be taken if this event occurs.
