The Environmental Protection Agency (EPA) is proposing to approve a revision to the air pollution control plan for California's San Joaquin Valley Unified Air Pollution Control District. This revision targets the reduction of harmful emissions of oxides of nitrogen and particulate matter from new development and transportation projects. The EPA is seeking public comments on this proposal until March 29, 2021, and if approved, it will become a part of the federally enforceable clean air plan. Despite some concerns about enforceability, the revised rule is seen as an improvement over previous regulations.
Simple Explanation
The EPA wants to change the rules to make the air cleaner in a part of California by making sure that new buildings and transportation projects don't release too much dirty stuff, like what comes out of car fumes. They want to hear what people think about this idea before deciding if it should be part of the official plan.
