Chapter 171 Fenceline Monitoring Report List
Petroleum storage facilities subject to the fenceline monitoring requirements of Chapter 171, Control of Petroleum Storage Facilities, began the required monitoring in August or September 2024. The start date of fenceline monitoring at each facility varies depending on the date the Department approved each facility’s fenceline monitoring plan.
In accordance with Chapter 171, fenceline monitoring data must be submitted to the Department on a quarterly basis, within 45 days of the end of each calendar quarter. The first quarterly submissions from facilities covering the 3rd quarter of 2024, are due no later than November 14, 2024. The Department will post reports to this website after a quality assurance review of the reports and data. This process is expected to take no more than 45 days, and reports will be available to the public by the end of each calendar quarter starting in December 2024.
