(2) A district may exclude a pollutant for monitoring at a refinery-related community air monitoring system and refinery fence-line monitoring system if substantial evidence supports that real-time monitoring of the pollutant is technologically infeasible or the pollutant would not be released by refining processes during routine and nonroutine operations at the refinery.
(3) A district shall, on a five-year basis, review the list of pollutants being measured and may revise the list of pollutants after
considering advances in monitoring technology, reported refinery emissions, ambient air data collected by the refinery fence-line and refinery-related community monitoring systems, and any other relevant emissions information.
(e) (1) The district and the owner or operator of a refinery shall collect real-time data from the refinery-related community air monitoring system and the fence-line monitoring system and shall maintain records of that data for at least five years. The owner or operator of a refinery shall post online quarterly reports that summarize pollutant levels, variations, and trends over a three-month period timeframe and notify the public of the availability of the reports.
(2) The data generated by these systems shall be provided to the
public within 24 hours in a publicly accessible and machine-readable format. The data shall be archived and made available to the public online for download through an application programming interface or other widely recognized standard and backend components shall be optimized to minimize delays in accessing data. The data shall include all historical and meteorological data, and pollution measurements and metadata, including latitude and longitude, detection limits, signal strength, calibration, and quality control checks.
(f) The owner or operator of a refinery shall conduct third-party audits, using an auditor approved by the district, of its fence-line monitoring system to ensure the system is providing accurate data, including conducting quality control checks, system calibration, and evaluation of quality control and assurance plans.
The audit reports shall be submitted to the district and made available to the public online by the refinery. The third-party audits shall be conducted in accordance with the following schedule:
(1) An initial audit shall be conducted as follows:
(A) For a fence-line monitoring system installed on or after January 1, 2024, within three months after the installation and operation of the system.
(B) For a fence-line monitoring system installed before January 1, 2024, by July 1, 2024.

audits shall occur every two years and review at least one year of monitoring data.
(3)If an initial, subsequent, or followup audit identifies deficiencies in the fence-line monitoring system, a followup audit shall be conducted within six months of
the completion of actions taken to correct the deficiencies identified in the audit.
(3) If an audit makes recommendations or identifies deficiencies in a fence-line monitoring system, the owner or operator of the refinery shall develop a corrective action plan within one month of the audit report to describe actions that will be taken to address all recommendations and deficiencies within a timeline of no more than six months. A follow-up performance audit shall be conducted within one month of completion of the corrective action plan to document the resolution of the recommendations and deficiencies identified in the audit. The owner or operator of a refinery shall implement all recommendations of the auditor for correcting deficiencies, except those that would cause a safety concern. The corrective action plan shall be
submitted to the district and made available to the public online by the refinery.
(g) The owner or operator of a refinery shall notify the district and public as quickly as possible of any exceedances of the lowest available one-hour average reference exposure or concentration levels set by the Office of Environmental Health Hazard Assessment or the United States Environmental Protection Agency that are detected by the fence-line monitoring system. At a minimum, the notification to the public shall include email and text message notifications to members of the public requesting notification by email or text message notification, as appropriate.
(h) (1) Within 24 hours of a fence-line system detecting an exceedance of a historical one-hour average
concentration of any measured pollutant, the owner or operator of a refinery shall initiate a root cause analysis to locate the cause of the exceedance and to determine appropriate corrective action. The owner or operator of the refinery shall prepare and submit a report to the district and post online within five days of the exceedance explaining the root cause analysis findings and corrective action performed by the refinery. The root cause analysis shall include a visual inspection to determine the cause of the exceedance and any of the following:
(A) Optical gas imaging.
(B) Leak inspection using Method 21 under Appendix A-7 of Part 60 (commencing with Section 60.1) of Title 40 of the Code of Federal Regulations.
