WECC-0157: PRC-006-5 Automatic Underfrequency Load Shedding, Update to the WECC Regional Variance

When the WECC variance was developed Requirement R15 language that allowed Corrective Action Plans to be developed was inadvertently left out. The proposed change(s) will allow the appropriate entities to collaborate on opportunities to provide effective remediation activities in a timely manner if there are deficiencies noted within an UFLS assessment activity. The goal is to consider how to incorporate the nation-wide Requirement R15 into the WECC Variance that will allow effective mitigation of a UFLS assessment not meeting performance criteria within the WECC Interconnection.
