Section 629-048-0130 - Visibility Objectives

(1) It is the intent under the Smoke Management Plan to comply with the Oregon Visibility Protection Plan (OAR 340-200-0040, Section 5.2).

(2) It is the intent under the Smoke Management Plan to operate in a manner consistent with the Oregon Regional Haze Plan, including the Enhanced Smoke Management Program (ESMP) criteria contained in the plan, for the purpose of protecting Class I Area visibility. These ESMP criteria include:

(3) When prescribed burning is conducted outside any Class I Area, an objective of the Smoke Management Plan is to minimize any smoke that impairs visibility inside the Class I Area. In addition to compliance with Smoke Management instructions issued in the daily forecast and compliance with all conditions of the burn permit required under ORS 477.515, burn bosses and field administrators are encouraged to closely observe local conditions at the burn site to avoid the main smoke plume entering a Class I Area at ground level.

(4) When prescribed burning is conducted inside a Class I Area, the Smoke Management Plan objective is to use best practices along with tight parameters for burn site conditions that will vent the main smoke plume up and out of the Class I Area and minimize residual smoke.
