Please find attached a cover letter and the body of the Request.

We did not reiterate the four studies in the request as we believe we have
agreement on them (to wit the current physical capacity of the system summer
and winter with a Winter NCP by customer as the allocater for the winter
period and the Summer NCP by customer as the allocater for the summer)  The
period of the NCP being the last 12 months (july to july).  This counts as
two studies.
The other two studies use the same system capacity and use as the respective
seasonal allocaters, the last five years average NCP by customer in Winter
and by customer in summer.

When you do these studies, would you also provide the definition used by El
Paso for Summer and Winter.  If you do not have one, we would suggest
November through April and May through October.

Please contact me with any clarifying questions.  1-800-883-8227.
