Federal Register Notice Publication and Ex Parte Rules
BPA anticipates the publication of the Federal Register Notices (FRNs) announcing the commencement of the TC-22 Tariff Proceeding and BP-22 Rate Case on Tuesday, Dec. 1, 2020. The FRNs will be posted on this website and the BP-22 website at that time.
Upon publication of each of these FRNs, ex parte rules with respect to that proceeding will begin and remain in effect throughout the duration of that proceeding. BPA’s Rules of Procedure, effective September 2018, prohibit ex parte communications during the TC-22 and BP-22 proceedings. A letter discussing the ex parte rules will be posted on this website and the BP-22 website upon publication of the FRNs.
The Prehearing Conferences for the TC-22 Tariff Proceeding and BP-22 Rate Case will be held in succession on Monday, Dec. 7, 2020, beginning at 9 a.m. The Prehearing Conference will be held virtually via WebEx (see details below). The TC‑22 Tariff Proceeding prehearing conference will begin immediately following the conclusion of the prehearing conference for the BP‑22 Rate Case.

Intervention Instructions
Any entity or person intending to become a party in the BP-22 and/or the TC-22 proceeding must file a petition to intervene through Bonneville’s secure website.  A separate petition must be filed for each proceeding. A first-time user of BPA’s secure website must create a user account and be granted access by the Hearing Coordinator to submit an intervention. Returning users may request access to the BP-22 and/or the TC-22 proceeding through their existing accounts, and may submit interventions once their permissions have been updated by the Coordinator. The secure website contains a link to the user guide, which provides step-by-step instructions for creating user accounts, requesting access, generating filing numbers, submitting filings, and uploading interventions. Interventions must conform to the format and content requirements set forth in BPA’s Rules of Procedure Sections 1010.6 and 1010.11. Interventions for the BP-22 and/or the TC-22 proceedings may be uploaded to the secure website starting Dec. 1, 2020. The deadline for submitting petitions to intervene is 4:30 p.m. on Tuesday, Dec. 8, 2020.
A petition to intervene must state the name and address of the entity or person requesting party status and the entity’s or person’s interest in the hearing. BPA customers and affiliated customer groups will be granted intervention based on petitions filed in conformance with the Rules of Procedure. Other petitioners must explain their interests in sufficient detail to permit the Hearing Officer to determine whether the petitioners have a relevant interest in the hearing. 
The deadline for opposing a timely intervention is two business days after the deadline for filing petitions to intervene. BPA or any party may oppose a petition for intervention. All petitions will be ruled on by the Hearing Officer.  Late interventions are strongly disfavored. Opposition to an untimely petition to intervene must be filed within two business days after service of the petition.
For questions regarding the intervention process, please contact the Hearing Coordinator via email at or, if the question is time-sensitive, via telephone at (503) 230-3107.
