1 A. Introduction 1. Title: Remedial Action Schemes 2. Number: PRC-012-WECC-CRT-1 3. Purpose: To establish a documented Remedial Action Scheme (RAS) review procedure 4. Applicability: The Applicable Entity designated in the Reporting Party field of Attachment A of this document is the Applicable Entity for purposes of each Requirement wherein the Reporting Party is used as the Applicable Entity. The Applicable Entity used in the Reporting Party field must be selected from through below. 4.1 Functional Entities: Transmission Owner Generator Owner Distribution Provider 5. Effective Date: June 21, 2017

2 B. Requirements and Measures WR1. Each Reporting Party shall use the process as established by the Remedial Action Scheme (RAS) Reliability Subcommittee (RASRS) when submitting a RAS for review. WM1. Each Reporting Party will have evidence that it used the process as established by the RASRS when submitting a RAS for review, in accordance with WR1. Evidence may include, but is not limited to, annotations in the minutes of the Operating Committee (OC), the RASRS, or correspondence between WECC staff and either the chair of the OC or the RASRS that indicates adherence to the process. WR2. Each Reporting Party shall review the WECC RAS database for accuracy and report any changes (or lack thereof), modifications, retirements, or expansions of its RAS to WECC, no later than December 31 of each calendar year. WM2. Each Reporting Party will have evidence that it reviewed the WECC RAS database and reported evidence of that review to WECC, no later than December 31 of each calendar year, in accordance with WR2. Evidence may include, but is not limited to, reports describing the review, the dates the review took place, and correspondence between the Reporting Party and WECC reflecting the required content. WR3. Each Reporting Party shall submit any additions, changes, modifications, retirements, or expansions of its RAS, to the RASRS or its successor, prior to placing the RAS or its changes into service. WM3. Each Reporting Party will have evidence that it submitted to the RASRS all proposed RAS changes prior to placing the RAS or changes to an existing RAS into service, in accordance with WR3. Evidence may include, but is not limited to, dated correspondence between the Reporting Party and either the chair of the OC or the chair of the RASRS describing the RAS in question and its proposed date of service, or production of studies run to establish and update seasonal System Operating Limits impacting the RAS. WR4. Each Transmission Owner, Generation Owner, and Distribution Provider shall assess its RAS(s) for operation, coordination and effectiveness, at least once each five years. WM4. This Requirement is to ensure assessment takes place on a periodic basis; reporting of that assessment is addressed in WR5 and WM5. Each Transmission Owner, Generation Owner, and Distribution Provider will have evidence that it assessed its RAS(s), at least once each five years, in accordance with WR4. Evidence that the assessment was conducted includes, at a minimum, production of a completed Attachment A of this document showing the results of the WR4 assessment.

3 Evidence may also include, but is not limited to, dated correspondence between the Reporting Party and either the chair of the OC or the chair of the RASRS describing the RAS in question and its proposed date of service, or production of studies run to establish and update seasonal System Operating Limits impacting the RAS. As to the completion date, for example, if the most recent assessment took place in June 2007, the next required assessment will be no later than June WR5. Each Reporting Party shall report the RAS assessment, required in WR5, by sending a completed Attachment A of this document to WECC no later than December 31 of the calendar year in which the assessment was completed. WM5. This Requirement is to ensure reporting takes place on a periodic basis; assessment of the RAS(s) is addressed in WR4 and WM4. Each Reporting Party will have evidence that it reported the results of its required RAS(s) assessment(s), by forwarding a completed version of Attachment A of this document, to WECC, no later than December 31 of the calendar year in which the assessment was completed, in accordance with WR5. As to the completion date, for example, if the most recent assessment took place in June 2007, the next required assessment will be no later than June 2012, with reporting to WECC no later than December 31, 2012.

4 Version History Version Date Action Change Tracking 1 June 22, 2011 WECC Board of Directors Approved Developed as WECC Version 1 to meet NERC FITB requirements 2 September 17, 2013 WECC Board of Directors Approved Developed as WECC Version 2 to meet Blackout recommendations. Adds more reporting requirements. 2.1 January 28, 2016 Errata Added NERC document titles after the associated NERC numbers. Replaced the word criterion with document to allow the document to remain current during document reclassifications. 2.1 April 1, 2016 No Change Converted to new template 2.2 June 15, 2016 Errata The reference to PRC-STD-3, Table 3, in Attachment A, Column 2, at the row designated Major WECC RAS, was updated to reflect: If this scheme is in the Major WECC Remedial Action Schemes (RAS) table, enter the number from the list. If the scheme is not on the Major WECC RAS List, enter NA. Note: As of June 13, 2016, this Table is currently referenced in PRC-004-WECC-1, Protection System and remedial Action Scheme Misoperation, (among other documents) and is located at [link as of ]. 3 June 21, 2017 WECC Board of Directors Approved Developed as WECC-0119B. This project: 1) deleted the fill-in-the-blank preamble, 2) removed references to the Reliability Assurer, 3) deleted WR1 through WR7 and WR12 eliminating the administrative tasks, 4) combined Attachment A and B into a single Attachment, and 5) added a Guidance section. This document replaces in its entirety PRC-(012 through 014)-WECC-CRT-2.2, Remedial Action Scheme Review and Assessment Plan.

5 Attachments Attachment A WECC RAS Initial or Periodic Assessment Summary Information on Attachment A will be used by the RASRS to ensure proper analysis, operation, coordination and effectiveness of the RAS. RAS Name Reporting Party The Reporting Party is identified using the following criteria: 1) The Transmission Owner is the Reporting Party. 2) Where there is not a Transmission Owner that owns a portion of the RAS, the Generator Owner becomes the Reporting Party. 3) Where there is neither a Transmission Owner nor a Generator Owner that owns a portion of the RAS, the Distribution Provider becomes the Reporting Party. When applying the above prioritization, if multiple entities (e.g. multiple Transmission Owners in the first described tier) own a portion of the RAS, those multiple entities may designate a single entity from that group to serve as the Reporting Party. If a single Reporting Party is not designated, all of the entities of the specified prioritization tier become responsible as the Reporting Party. Group Conducting this RAS Assessment Assessment Date Review the scheme purpose and impact to ensure proper classification, is it (still) necessary, does it serve the intended purposes, and does it continue to meet current performance requirements. This RAS assessment included the following: Study Years

6 System Conditions Contingencies analyzed (select what applies) N-1 N-1-1 N-2 Extreme Date when the technical studies were completed Does this RAS comply with NERC standards and WECC criteria? Discuss any coordination problems found between this RAS and other protection and control systems during this (most recent) assessment. Provide a Corrective Action Plan if this RAS was found to be non-compliant or had coordination problems during this (most recent) assessment (should be NA for owner s initial assessment).

7 Rationale A Rationale section is optional. If Rationale Boxes were used during the development of this project, the content of those boxes appears below. Guidance Section RAS Classifications RAS classifications such as Wide Area Protection Scheme, Local Area Protection Scheme, and Safety Nets are addressed by the Remedial Action Scheme Reliability Subcommittee, under the auspice of the Operating Committee, in the Procedure to Submit a RAS for Assessment, Information Required to Assess the Reliability of a RAS Guideline, as updated from time-to-time. Definitions for these terms were contained in Version 1, Attachment A of this document, but have shifted directly to the RASRS. As a result, the terms are no longer included in the WECC Glossary of Terms and Naming Conventions. Role of the RASRS and the WECC RAS Database When the first version of this document was approved it met the NERC fill-in-the-blank (FITB) requirement to establish a WECC RAS database. The initial version required completion and submittal of a data set regarding RAS from which the WECC Remedial Action Scheme Reliability Subcommittee (RASRS) created the WECC RAS database. It is the WECC RASRS that maintains that database. The FITB standards described a discrete minimum data set for inclusion in the WECC RAS database but were silent on WECC s ability to expand on that minimum. Since the RASRS maintains the database, the RASRS also maintains the procedure whereby the database is populated. Instructions and explanations regarding the database are currently found in the Procedure to Submit a RAS for Assessment, Information Required to Assess the Reliability of a RAS Guideline, Revised: October 28, 2013, see pages 9 and 10 (Procedure). Because the Procedure is owned by the RASRS under the auspice of the Operating Committee (OC), its contents may change from time-to-time under the due process rules of the OC. Questions about that document should be directed to the RASRS. WR4 WR4 does not require that all RAS be reviewed at the same time, only that each RAS is reviewed at least once each five years. Staggered review is allowed under the requirement.
