<p class="MsoNormal">Attached is a draft of WP 8 for NSP/6. The paper includes a change proposal for the SARPs to allow for Eig to be > 2.75 in some cases where operational requirements permit. Please review the WP before our meeting on Wednesday 10/7. Comments
can be provided in advance to myself, Matt Harris and/or Linda Lavik.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There is a companion paper (WP 9) that will contain much of the validation information for the proposed change. We will circulate that paper soon, also for review prior to the meeting.<o:p></o:p></p>
