I would like to start the dialogue in what will be a series of meetings to discuss the impact of non-spec gas on Northern's system and explore solutions to the problems created by the non-spec gas. The following list of issues will be addressed on November 8 and at subsequent meetings. Randy and Danny, will you please select a representative or representatives from your respective regions to be a participants on this project?

List of Issues to be explored:

Identify the contaminants/gas quality problems

What is our tariff specification of each contaminant?

System impacts resulting to taking non-spec gas

Cost to system to accept non-spec gas

Revenue impact of non-spec gas

What is the tariff spec of other interconnecting pipelines?

Possible solutions by region and contaminant/problem

Impact of proposed rules which will require Northern to post tariff waivers on gas quality

This list of issues will be expanded and modified as this project moves forward. Please feel free to contact me if you have questions.

Feel free to invite others to this meting that I have not included in the notification of this meeting.
