The Oregon Department of Environmental Quality is hosting a public hearing about Intel's proposed air quality permit from 6-9 p.m. tonight at the Hillsboro Civic Center. As the Hillsboro Argus/OregonLive reported last week , the state proposes approving an expansion of Intel's semiconductor facilities at the company's Aloha and Ronler Acres campuses and approving higher limits for air pollutant emissions because of the expansion.
