*** UPDATED 10/01/2024 ***

On September 30, 2024, between 2:50 PM and 3:20 AM, a Rule 1180 Community Air Quality Notification for Acetaldehyde at Hudson Air Monitoring Station was incorrectly issued by South Coast AQMD. We have identified and corrected the cause of the error leading to the false alert notification being sent to the subscribers. We are working on improvements to notifications quality control to prevent this error in the future. 

Acetaldehyde concentrations at the Hudson Station did not exceed a 1-hour standard; and acetaldehyde concentrations at the Rule 1180 community air monitoring stations remain within normally observed levels.

We apologize for any inconvenience or confusion this may have caused you. Maintaining the accuracy and reliability of our notifications is of paramount importance to us, and we will take additional measures to prevent such errors in the future.

Thank you for your understanding and ongoing support as we strive to provide you with the most accurate and reliable community air quality information.

Background

Community air monitoring near all major refineries in the South Coast Air Basin (Basin) is being conducted as part of the Rule 1180 Program. Rule 1180 was adopted by the South Coast AQMD Governing Board on December 1, 2017 and requires all large petroleum refineries in the Basin to collect emission data at or near their fenceline, and to provide data quickly to the public.  To this end refineries are required to install and operate continuous fenceline air monitoring systems to monitor a comprehensive list of criteria and toxic air pollutants in real-time.  Rule 1180 also establishes a fee schedule, to be paid by the refineries, for the cost of designing, developing, installing, operating and maintaining refinery-related community air monitoring sites.  Community air monitoring is conducted by the South Coast AQMD in accordance to the Rule 1180 Community Air Monitoring Plan (CAMP).

Main Goals and Objectives

  • Implement a robust, continuous and near real-time community air monitoring network near all refineries in the Basin;
  • Provide near real-time air quality information through a dedicated website to inform the public of current air quality conditions in their community;
  • Notify the public in case the ambient concentration of one or more air pollutants exceeds pre-determined thresholds
  • Collect air pollution data suitable for short- and long-term air quality assessments;
  • Provide up-to-date community air quality data;
  • Promote awareness of the potential impact of refinery emissions on air quality through public education;
  • Track progress in improving community air quality.
