Fenceline Monitoring Plans

Read about regulations governing oil refinery fenceline monitoring and view plans and data provided by the five local refineries.

Refinery Fenceline Monitoring Regulations

Fenceline air monitoring at refineries is used to measure specific pollutants that cross the facility’s fenceline in real time. The systems have the ability to monitor, record, and report air pollutant levels of multiple compounds. The Air District's Regulation 12, Rule 15 - Refining Emissions Tracking Rule includes a requirement that Bay Area refineries establish Air Monitoring Plans and operate fenceline air monitoring systems consistent with guidelines developed by the Air District.

These guidelines require that each refinery shall post their fenceline monitoring data to a website where the near real-time results can be viewed by the public. Links to each facility’s fenceline monitoring webpages are provided below:

Refinery Air Monitoring Plans

The Air District has provided each Refinery’s approved Air Monitoring Plan in the table below . Each plan is subject to further revision at the request of the Air Pollution Control Officer.

Under Regulation 12-15, each Air Monitoring Plan must include:

  • A plan for establishing and operating a fenceline monitoring system to aid in determining specified pollutants that cross the refinery fenceline(s) in real time;
  • Detailed information describing the equipment to be used to monitor, record, and report air pollutant levels; and
  • The siting, operation, and maintenance of this equipment and procedures for implementing data quality assurance and quality control.
