California air regulators get conditional approval for a new pollution plan

The US environmental regulators have given conditional approval to a new air pollution plan for California's Bay Area. This means the local air quality district can move forward with its plan, but it must address specific issues to get full approval.

This conditional approval means the Bay Area Air Quality Management District can start implementing parts of its plan to reduce air pollution. However, the US environmental regulators still need more information on how the plan will reduce emissions from certain sources. The conditional nature of the approval means the district must still prove its plan will actually work to meet federal air quality standards.
