(Salem, OR)  --  Oregon OSHA says it will lift its mask requirement when the state reaches a 70-percent vaccination rate for COVID-19.  The agency announced the plan yesterday.  Mask mandates will remain in place for airports, public transit and health care settings.  The new guidance is in alignment with the governor's guidance issued last week.  Oregon is expected to reach the 70-percent vaccination rate as early as June 21st.
