PURPOSE: Use Nitrogen (N2) to purge from Taylor Station (7-36-82-18W6) to Bonanza Station (13-36-79-13W6); ~62.5 kms of 10” Pipeline. This is being done to facilitate the replacement of 1.5 kms of Pipeline between the Taylor Station and the Peace River valley.

SPECIFIC EQUIPMENT INVOLVED: Nitrogen Pumper, Nitrogen Bulkers, Temporary Piping, P-Tank, Flare Stack and Related Equipment, Locks, & Blinds.

POTENTIAL HAZARDS INVOLVED: Nitrogen asphyxiation, High pressure product, Noise, Flammable Product Release, Benzene, Pinch points, Extended work hours, Fatigue, Temporary piping, Slips, Trips and Falls

REQUIRED PERSONAL PROTECTIVE EQUIPMENT: Fire Retardant Coveralls, Side Impact Hard Hats, Safety Glasses, CSA Approved Steel Toe Boots, Four Head Monitor, Hearing Protection, SCBA/SABA , Communication Equipment, Brass Hammers, Wind Socks, Fire Extinguishers

REQUIRED EQUIPMENT ISOLATION: MOV-UV0215 at Taylor will be closed and Locked Out. The manual kicker valve (FN-1110) into the 10” trap at Taylor will be closed and Locked Out. Once the N2 purge is completed; both MOV-UV0214 and FN-1100 will be closed and locked out and a 10” 600# blind will be installed between these two valves. Once the Blowdown is completed, the two MOV Block valves at Bonanza Station (FN-1200 & FN-2100) will also be closed and locked out, with a 10” 600# blind installed between them.

OTHER COMMENTS SPECIAL TO THIS PROCEDURE: All Standards and SOP’s referred to in the NRTA are attached for reference.

9. Bonanza Station - Pre-Job meeting and Hazard assessment. NRTA review

The N2 purge and blowdown will take between 25 – 35 consecutive hours, which will result in multiple shift and different personnel on-site.

Separate pre-job meeting will be held at both the Taylor and Bonanza sites, as the distance between the two is excessive. Proper communications between the two groups is absolutely essential.

Continue tracking the pig along the pipeline into Bonanza Station – reporting back to both the Taylor and Bonanza crews on its location.

Watch for school zones and buses.

Drive with courtesy.

Bear spray

Air Horn

Use check in system

14 Once the anticipated arrival time is less than 1 hour away, the Taylor Crew should lower the N2 injection rate to slow down the pig speed.

The Bonanza crew can partially close the incoming (FN-1200) and discharge (FN-2100) valves to ensure the purge pig does not go past the Bonanza Station. No more than half way closed.

N2 Crew, Pembina Ops N2 Pumper, MOV’s, pressure gage

Too much restriction, over pressuring, possible hydrate

Continuous monitoring of the pressure is needed.

Personnel must be ready to close the Bonanza station discharge valve when the pig arrives.

15 When the purge pig arrives at Bonanza, the station discharge valve (FN-2100) must be closed and immediate notification to the Taylor crew to stop pumping N2, if job site supervisor has not already instructed the Taylor crew to stop pumping. Discharge valve FN-2100 can now be locked out.
