State gets more strict on covering your face

I saw this article on the Oregonian's website earlier today as well, but could not find any updates to the mandate on the Oregon.gov websites including the official coronavirus websites. https://govstatus.egov.com/or-covid-19 and https://govstatus.egov.com/or-oha-face-coverings Both of these official websites indeed state that face coverings are required, but they very clearly state that this applies when social distancing is NOT possible. What source is being cited for reporting that masks should be worn in all situations? Thank you.
