§ 40002 County Air Quality Districts

Key Takeaways

  • •Every county in California has its own air quality district unless it's part of a bigger, special district.
  • •If part of a county is in a special district (like the bay district or south coast district), the rest of the county still has its own air quality rules.
  • •Different areas can have different rules to keep the air clean.

Example

Imagine you live in a county where half is in the 'bay district' and the other half is not.

The half in the 'bay district' follows the bay district’s air rules, like limits on factory smoke. The other half follows the county’s own air rules, which might be different. So, a factory in the county part might have different smoke rules than one in the bay district part.
