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.

Proposed Draft Regulation 11, Rule 18: Reduction of Risk from Air Toxic Emissions at Existing Facilities

The Air District is developing a proposed draft regulation to reduce health risks from toxic emissions from existing facilities.

Draft Regulation 11, Rule 18: Reduction of Risk from Air Toxic Emissions at Existing Facilities 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.  

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

Past Proposed Rules

Refinery Strategy

The Air District has a four-part plan for addressing emissions from petroleum refineries.

  1. Reduce Harmful Emissions
  2. Continuous Monitoring
  3. Limit Pollution & Protect Health
  4. Ensure Best Practices

Reduce Harmful Emissions

The Air District is developing a suite of regulations to reduce emissions of criteria pollutants from Bay Area refineries by 20 percent (or as much as feasible) by 2020. The first phase of these regulations will be considered by the Board in December 2015 and includes:

  • Regulation 6, Rule 5, which will limit ammonia emissions from fluid catalytic cracking (FCC) units, which will reduce associated formation and emission of fine particulate matter (PM2.5). 
  • Regulation 8, Rule 18 amendments, which will reduce emissions of organic compounds, toxics and methane from equipment handling heavy liquids.
  • Regulation 9, Rule 14, which will reduce sulfur dioxide (SO2) from coke calcining.
  • Regulation 11, Rule 10 amendments, which will reduce organic compound and toxic emissions from cooling towers.

The Air District received many written comments during the comment period that closed on November 23, 2015. Public comments and draft rule documents are available for review on the Public Hearings page.

These new videos provide a brief overview of the four regulations: 

Regulation 6-5 and the amendments to Regulation 8-18 and Regulation 11-10 were adopted on December 16, 2015. Regulation 9-14 was adopted on April 20, 2016.

In mid-2016, the second phase of the strategy will further reduce:

  • SO2 from FCC units and other refinery sources
  • PM2.5 emissions from FCC units
  • Nitrogen oxide NOX emissions from turbines

Continuous Monitoring

Draft Regulation 12, Rule 15, Petroleum Refining Emission Tracking will require:

  • Continuously updated, state-of-the-art methods be used to calculate and report the total pollution from the refineries every year.
  • Extensive air quality monitoring to validate those pollution calculations and ensure that surrounding communities are not subjected to unhealthy levels of pollution.
  • Requirements that will use emission inventories and monitoring data to identify potential reductions.
  • An energy audit identifying potential improvements to reduce climate pollutants.
  • New, more protective Health Risk Assessments be performed to determine health risk from toxic air pollutants.

The Air District received many written comments during the comment period that closed on November 23, 2015. Public comments and draft rule documents are available for review on the Public Hearings page.

Regulation 12-15 was adopted on April 20, 2016.

Limit Pollution & Protect Health

Draft Regulation 12, Rule 16, Petroleum Refining Emissions Limits and Risk Thresholds, will:

  • Limit refinery criteria pollutant and toxic emissions to levels and minimize the health burden for the surrounding communities
  • Require Health Risk Assessments have updated information every year as new emissions data are received

The Air District received many written comments during the comment period that closed on November 23, 2015. Public comments and draft rule documents are available for review on the Public Hearings page.

Ensure Best Practices

The Air District is developing changes to Air District permitting regulations to ensure that when refineries modernize or make significant changes to the type of crude oil they use, they will be required to use the best available control technology to reduce smog-forming, toxic, and climate pollutants. Over time, these changes to the permitting regulations will ensure the refineries use best practices and operate as efficiently as possible.

The Air District will be working on this rulemaking in 2016 and there will be many opportunities for public comment and input.

Past Proposed Rule Amendments

Wood Burning Rule Amendments

The Air District is seeking to adopt regulatory amendments to Regulation 6, Rule 3 to further reduce fine particulate emissions from wood burning.  Written comments on the proposed rule amendments must be received by 9:00 a.m. on Monday, October 19, 2015. A public hearing to adopt these proposed amendments is scheduled for Wednesday, October 21, 2015.

These amendments to Regulation 6, Rule 3, were adopted on October 21, 2015.
