CHANNEL GAS PIPELINE

PHASE II – From MLV 812 to Lomax

Installation of Pigging Equipment & Smart Pigging Project

Saturday April 7, 2001 – Preparation Day (1 day)
Verify & record on line gas chromatograph readings @ MLV 812 & Lomax (56001).
Verify & record dew point readings @	MLV 812 & Lomax (56001).
Dregger Tube – water dew point, H2S length of stain, 
Verify water content, hydrocarbon content, btu
Water content – Entrained liquids - Length of stain - C5 plus 

	Compressors are in place @ Station 812

Sunday April 8, 2001 – Pull Pipeline Pressure Down ( 1 day)
07:00 am	- Have Flow Day Complete
	- Begin putting upstream west side Lomax stopple in place.
- Shut, lock & tag out all receipt & delivery points.
- Close MLV 812.

The 20” Ship Channel will be fed from the east end of the system.  Gas has to be scheduled on the east end of the pipe to satisfy all deliveries in the 20” Ship Channel.  The east end from Lomax to Sabine River will be scheduled flat.

08:00am – Begin pulling gas from downstream east side of MLV812 & discharging gas into upstream west side of MLV812.
	- These compressors will pull the pressure down from 650psi to 200psi.  This should take 18 hours.

Monday April 9, 2001 – Construction Days (2 days)
04:00am – Pipeline down to 200psi

- Remaining pressure will be blown down at MLV 812
- Verify pipeline pressures at MVL 812 & Lomax.

07:00am – Contractor receives pipeline to begin modifications.

Wednesday April 11, 2001 – Pipeline Cleaning Days (7 days)
07:00am 	- Cleaning Contractor begins cleaning using air compressors & diesel diluent.

Wednesday April 18, 2001 – Repair Pipeline Day (1 day)
07:00am – Begin installing pup in damaged section of pipe

Thursday April 19, 2001 – Purging & Loading Day (1 day)
07:00am - Begin purging & loading line
- Purge, load & pressurize pipe from MLV 812 to upstream west side Lomax stopple
	- Equalize pressure across upstream west side Lomax stopple.
	- Downstream east Lomax stopple will remain open to insure flow of gas up 20”.
	- Equalize pressure across upstream west Lomax stopple.

Friday April 20, 2001 – Remove Upstream West Side Lomax Stopple (1 day)
07:00am – Begin removing upstream west side Lomax stopple.
- Verify flow of gas past MLV 812 (ultrasonic meter) towards Lomax

	- When the upstream west side Lomax stopple is removed gas flow will return to normal (flowing from west to east).		  The receipt gas for the 20” Ship Channel deliveries needs to be scheduled on the west end of the pipe.  This will allow		  the pigs to be run from MLV 812 to Lomax.

Saturday April 21, 2001 – Run Caliper Pig Day (1 day)
07:00am – Run Caliper Pig from MLV 812 to Lomax
	- Approximately 150-200mmbtu is required to run the caliper pig.  The pig will run from 4 mph to 8 mph requiring 3.2		 to 6.5 hours.

Sunday April 22, 2001 – Run Smart Pig Day (1 day)
07:00am – Run Smart Pig from MLV 812 to Lomax
	- Approximately 150-200mmbtu is required to run the caliper pig.  The pig will run from 4 mph to 8 mph requiring 3.2		 to 6.5 hours.

Monday April 23, 2001 – Smart Pig Results Day
	Good Run or Bad Run Decision will be made today.

PHASE II ENDS (15 days)

Installation of Pigging Equipment & Smart Pigging Project
PHASE II – From MLV 812 to Lomax Area
POINTS TO BE SHUT-IN, LOCKED & TAGED OUT.

The following points will be scheduled zero from flow day of April 08, 2001 thru flow day of April 22, 2001.  Including the 20” ship channel to the Sabine River will be scheduled flat.  From the Seeligson Check Valve to MLV 812 will be scheduled flat.
