Remotely Detected Emission Plumes
(14) Within five (5) calendar days after receiving an emission plume detection notification pursuant to section 95669.1(a), if section 95669.1(b)(1) applies, report the date of the CARB notification, the emission ID provided in the notification, and a description of the venting, including a brief summary of the source of the venting and why the venting occurred.(15) Within 72 hours after conducting an inspection pursuant to section 95669.1(b), report all the following information:(A) The date of the CARB notification.(B) The emission ID number provided by CARB in the notification.(C) The date of the inspection.(D) The type of inspection performed (Method 21 or optical gas imaging).(E) The type of emission source found, which shall be no emission source, a venting emission source, a leak detected using Method 21, or an unintentional emission source detected using optical gas imaging.(F) The initial mitigation plan, unless the emission source is not found or is a venting emission source. The initial mitigation plan shall consist of a statement of whether the emission source has already been successfully repaired and, if not, a brief description of what actions the owner or operator anticipates taking to repair the emission source.(16) Within five (5) calendar days after conducting an inspection pursuant to section 95669.1(b), if section 95669.1(d)(1) applies, report the emission ID provided in the notification and a description of the venting, including a brief summary of the source of the venting and why the venting occurred.(17) Within five (5) calendar days after repairing a remotely detected emission source pursuant to sections 95669.1(d)(2), 95669.1(d)(3)(B), or 95669.1(d)(4), report the emission ID provided in the notification, the type of equipment associated with the emission source, and the date of repair. If the emission source was a leaking component, also report the type of component, the date of the US EPA Reference Method 21 (October 1, 2017) measurement, the initial leak concentration, and the post-repair leak concentration.(18) Within five (5) calendar days after performing a US EPA Reference Method 21 (October 1, 2017) measurement following an optical gas imaging inspection (in response to a remote emission detection) that does not result in finding a leak over the leak concentration threshold as described in section 95669.1(d)(3)(A), report the emission ID provided in the notification and a statement that the follow-up US EPA Reference Method 21 (October 1, 2017) measurement did not show a leak over the leak concentration threshold.(19) Annually, report the information specified in Appendix A, Table A8 for all remotely detected methane emission plume notifications received pursuant to section 95669.1(a). Delay of Repair
