Rule 1180 - Refinery Fenceline Air Monitoring Plans

Latest Updates:
Public comments and South Coast AQMD staff responses are now posted
Partial approvals of the fenceline air monitoring plans have been issued for all refineries, see table below for partial approval letters

This site will be updated as new information becomes available.

Adopted in December 2017, Rule 1180 mandates the implementation of real-time observations of air quality at or near the fenceline of all major refineries in the South Coast Air Basin, and in nearby communities.

The main objectives of Rule 1180 are to:

  • Provide real-time information about air pollutant levels at the refinery fenceline and in nearby communities
  • Understand long-term variations and trends of refinery related emissions
  • Help communities understand potential air quality impacts of refinery emissions
  • Provide a notification to the community if emissions exceed pre-determined thresholds
  • Enable refineries to quickly address significant changes in emissions

The timeline for Rule 1180 fenceline and community air monitoring implementation is summarized in the chart below.

Fenceline Air Monitoring

Rule 1180 requires petroleum refineries to install and operate fenceline air monitoring systems to measure a comprehensive list of criteria pollutants and toxic air contaminants. For each applicable refinery, the rule requires the submittal and approval of a fenceline air monitoring plan that provides detailed information about air monitoring instrumentation, maintenance and quality control procedures, backup systems, auditing, and data reporting methods. All fenceline air monitoring plans shall be consistent with the Rule 1180 Refinery Fenceline Air Monitoring Plan Guidelines developed during the rulemaking process. Prior to approval or disapproval the fenceline air monitoring plan shall be made available for public review for no less than fourteen (14) days. Comments received will be considered for modification of the draft plan, prior to its official approval/disapproval.  

In August 2018 all refineries submitted to South Coast AQMD their draft fenceline air monitoring plans. Upon the initial review of the plans, South Coast AQMD staff determined that all submitted plans had major deficiencies. Staff worked with each refinery individually to improve the plans. As a result of this work, all refineries submitted their revised draft fenceline air monitoring plans which were made available for public review. 

South Coast AQMD staff would like to thank everyone who provided feedback on the plans for their thoughtful comments and suggestions. All comments received were carefully considered to determine if modifications of the draft plans should be made, prior to their official approval or disapproval.

Public comments submitted on draft refinery fenceline air monitoring plans can be viewed here.
A summary of the public comments and South Coast AQMD staff responses can be found here.

Following review and analysis of the public comments, staff worked with each refinery to modify their proposed fenceline coverage in order to address the concerns raised by the public. All refineries agreed to modify their proposed fenceline coverage by including additional open-path and point instruments, and South Coast AQMD staff determined that the revised fenceline coverages are adequate to satisfy the requirements of Rule 1180. Therefore, all refineries received partial approvals of their fenceline monitoring plans. Partial approvals are granted to the fenceline air monitoring portion of the plans only. South Coast AQMD staff will continue working with all refineries on all other elements of the fenceline monitoring plans, namely: back-up monitoring and maintenance, data presentation to the public, public notifications and notification thresholds, and quality assurance / quality control (QA/QC). The partial approval letters for each refinery are linked in the table below.
