All PRRs and related activity are publicly available through the BPM change management site at http://bpmcm.caiso.com/Pages/default.aspx.
The PRR listed below has an open 10-business day comment or appeal period from Oct. 17, 2019 through October 31. Due to the timing of submittal, PRR 1202 will be discussed during the November and December BPM change management PRR review monthly meetings.

BPM Library updates
The reference document on the ISO website lists the updated BPMs in the library.
The ISO may unilaterally make and implement revisions to the BPMs in emergency circumstances, as set forth in Sections 22.4.3 and 22.11 of the ISO Tariff and in Section 2.6 of the Business Practice Manual for BPM Change Management. An emergency PRR will continue through the BPM change management stakeholder process to obtain stakeholder input on the revisions and make other recommendations, as necessary.
Please note that affected parties must register in order to submit a PRR or written comments.
More information on the BPM change management process is available on the ISO website at http://www.caiso.com/rules/Pages/BusinessPracticeManuals/Default.aspx.
