Current Proposed Rules 

Proposed Rule Changes to Regulation 6: Particulate Matter

The Air District is proposing amendments and additions to Regulation 6, which governs particulate matter emissions from various commercial and industrial operations. The Air District estimates that several hundred facilities may be subject to these proposed rules.

The amendments and additions involve the following rules:

  • Amendments to Rule 1: General Requirements
  • New Regulation 6: General Provisions, Definitions and Test Methods
  • New Regulation 6, Rule 6: Prohibition of Trackout
  • New Regulation 6, Rule 7: Roofing Asphalt
  • New Regulation 6, Rule 8: Bulk Material Storage and Handling

The current Regulation 6, Rule 1, was most recently amended in December 2007. These new draft amendments to Rule 6-1 bring it up to date with California’s strictest particulate matter requirements. The Air District has drafted several new rules to address other sources of particulate matter.

Key Upcoming Rules

The Air District is developing several proposed draft regulations to reduce or cap emissions from existing facilities.

  • Draft Regulation 11, Rule 18, would improve air quality and reduce toxic emissions from facilities ranging in size from large-scale plants like factories and oil refineries to smaller operations like back-up generators and gas stations. The Air District estimates that hundreds of facilities throughout the Bay Area may be subject to the proposed rule, which would incorporate recently adopted risk management guidelines and health risk values from the California Office of Environmental Health Hazard Assessment.
  • Draft Regulation 12, Rule 16, proposed by a coalition of advocacy organizations, would place a numeric cap on greenhouse gas and other emissions at refineries.
  • Draft Regulation 13, Rule 1, is the first in a series of regional rules that address greenhouse gases and related pollutants. Rule 13-1 would cap the carbon intensity per barrel of crude oil refined at each Bay Area refinery.

More information and supporting materials, including the draft staff report for Draft Regulation 11, Rule 18, and Draft Regulation 12, Rule 16, can be found on the Regulatory Workshops pages.

Past Proposed Rule Amendments
