The first item shown is the Number of Wells Currently on the Permit. The current number of wells may not match the original number of wells on the permit because of renewals or modifications. The second part of the table is the Original Permitted Flow. Then, the Current Total Flow is shown, this includes the current flow for all constructed outfalls. Next, the number of wells added with this renewal are multiplied by the original permitted flow per well/day resulting in the Potential Added Flow. The Potential Added Flow is added to the Current Total Flow to get the Maximum Expected Flow for this permit renewal. The Maximum Expected Flow is subtracted from the Original Permitted Flow producing the Unused Flow.

Average flow January 2005 through June 2005, MGD

With the addition of 17 wells and the removal of three wells the above calculations show that the original permitted flow would not be exceeded, therefore this permit renewal will maintain the original total flow of 2.052 MGD.
