1999-06-02 00:00:00 | [NAME]  [NAME]   [NAME]  [NAME]      [NAME] Fawcett-TW (Mrkt)        [NAME] Tanner- TW                    3 Griffith Representatives | A preliminary design had been prepared by TW and it was discussed along with the general design criteria.  Most of the discussion was on: if both pipelines needed to be tapped,  Powerplant EIS and schedule, delivery pressure, volumes, site condition-proposed new 230 Kv overhead electric line, easements, need for a control valve to prevent over-pulls, if the valve would be set on flow control or pressure control, pressure drop through the proposed 6" control valve, if Citizens could get a pulse from the meter, gas odorization (sulfur content), and site security.
2000-01-04 00:00:00 | [NAME]  [NAME] (names not documented) | Minimum flow rates were not understood in the original conference call.  When Griffith provided the low flow requirements of 1,424 SCFH TW presented a strategy of handling without the additional runs.  The estimate and maximum reimbursement amount in the executed Delivery Point Agreement were based on a single 10" meter run. [NAME] indicated that he would allow as long as operational difficulties were not encountered.
2000-01-06 00:00:00 | Draft Letter (Attached) | The low-flow strategy was reviewed  internally by TW.
2000-02-01 00:00:00 | TW | Bid Drawing of the Station were plotted and soon after sent to [NAME] for a custody review and for coordination with the proposed Citizens Facilities.
Start-Up Period | Citizens and TW Operations personnel | The TW Interconnect station came on line with a flow control valve along with a pressure override valve. The pressure settings were roughly 650psig to 950 psig, producing erratic swings in the delivery pressure.
Start-Up Period | Citizens, Trigon and TW Operations personnel | Per a request from [NAME] (Trigon), [NAME], request the tightening of the pressure swing that the TW Interconnect Station operated between. The new operational pressures were about 750 psig to 950 psig, but I don't think the station never operated under these conditions, because the plant was down.
Start-Up Period | Citizens and TW Operations personnel | Citizens' [NAME] requested that the pressure override be removed from the station, which it was for a while.
Start-Up Period | Citizens, Trigon and TW Operations personnel | After TW, Trigon, and Citizens observed Citizens Station controlling erratically, TW put the pressure override back into service due to concerns of over-pressuring Griffith's "customer owned piping"
August 17, 2001 | Citizens and TW Operations personnel | Citizens then requested TW to once again remove the pressure override from the station, and that is how the station operates today.
Early Nov. 2001 | [NAME] talked to [NAME]. | Citizens requested TW to evaluate making a pressure cut at the TW Griffith Interconnect.
Late Nov. to early Dec. 2001 | [NAME], [NAME]. | [NAME] left several messages inquiring if TW would honor the requested pressure cut.
2001-12-12 00:00:00 | [NAME], [NAME], [NAME] | Citizens made this pressure cut request to TW Marketing.
2001-12-13 00:00:00 | [NAME], Darrell Schoolcraft | Discussed the history of the design and operation of the station.  [NAME] emailed a copy of the preliminary vibration report, Schoolcraft stated that TW would discuss the subject and let [NAME] know by December 21, 2001.
