(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 data are available, 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 to various background visibility levels as displayed in Department Directive 1-4-1-601, “Operational Guidance for the Oregon Smoke Management Program.”
- (4) Smoke incidents and smoke 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 that average at or above the 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.
