Re:    Constituent Mod for North Beaver Creek-Little Buffalo Opt. 2
       WYPDES Option 2 Permit – WY0048143
       Pennaco Energy, Inc.

Dear Ms. Zygmunt:

Please approve the enclosed Constituent Modification.

This constituent modification seeks to align field and regulatory requirements with
current policy. Thus, this request is to raise the limits for total radium 226, dissolved
iron, and pH to current WDEQ standards for those outfalls that are located more than one
stream mile from a class 2AB channel.

In addition, please update the Initial Monitoring Requirements to current regulatory
standards.

Outfalls greater than one (1) stream mile from a 2AB channel:

                Outfall #            Distance to 2AB              Nearest Class 2AB
                  001                     31.72                     Powder River
                  002                     29.72                     Powder River
                  003                     30.76                     Powder River
                  004                     30.37                     Powder River
                  005                     30.01                     Powder River


Compliance Discussion: The outfalls listed above are located in a new development area
and have not been constructed. However, PEI would like to update the permit to reflect
current WDEQ policy before construction.
