The county Board of Supervisors, sitting as the local Air Pollution Control District board, will conduct a public hearing this week to consider adopting revisions to the state implementation plan for dust pollution.
The item is tentatively scheduled for 11 a.m. Tuesday. The board meets in open session at 9:30 a.m. in the County Administration Center, 940 W. Main St. in El Centro.
The county's dust pollution is the subject of a lawsuit filed in June by the Sierra Club's Earthjustice Legal Defense Fund against the U.S. Environmental Protection Agency. The environmental group is asking a federal court to order the EPA to either declare the Valley's air quality meets federal clean air standards for airborne particles, called PM-10, or, if the Valley's air-quality standards do not meet the federal standards, that EPA be ordered to reclassify the Valley's air quality to a more stringent classification called serious nonattainment.
The plan is expected to impose those requirements to bring the county into attainment.
