If a pipe section is so cracked that it cannot withstand this test that section of pipe
needs to be replaced now. Enbridge can use pigs to identify and replace most cracked sections before a hydro static test. However, pigs are not 100% reliable, especially with respect to external cracks that are adjacent to welds. Hence there is no substitute for a full scale hydro static test to 150% of MAOP. Testing to 125% of MAOP, as contemplated in CSA Z662-11, is not good enough because it does not give an adequate working life to the pipe after the test. A test to 125% of MAOP on a 0.25 inch wall pipe merely shows that there are 0..05 inches (1.27 mm) of safety margin. Cracks are known to penetrate such pipe wall at rates in the range .15 mm / year to .40 mm/ year.</div><div style="font-family: 'Helvetica Neue', 'Segoe UI', Helvetica, Arial, 'Lucida Grande', sans-serif;"><br clear="none"></div><div style="font-family: 'Helvetica Neue', 'Segoe UI', Helvetica, Arial, 'Lucida Grande', sans-serif;">Hence under
CSA Z662-11 the working life of the pipe after pressure testing until the next pressure test is in the range:</div><div style="font-family: 'Helvetica Neue', 'Segoe UI', Helvetica, Arial, 'Lucida Grande', sans-serif;">(1.27 mm / .4 mm) = 3.2 years to (1,27 mm / ,15 mm) = 8.5 years. I highly doubt that we want to revisit this matter only three years hence. Thus it is essential that everyone insist on a hydro static pressure test to 150% of MAOP. TELL YOUR FEDERAL MPs AND PROVINCIAL MPPs THAT NOTHING LESS THAN A HYDRO STATIC PRESSURE TEST TO 150% OF MAOP is satisfactory. CSA Z662-11 is intended for new pipelines in rural areas, not for old pipelines in the middle of Toronto. The NEB process and CSA Z662-11 are both designed to maximize pipeline company profits, not address public safety. THIS PIPELINE DOES NOT MEET PROVINCIAL SAFETY STANDARDS! </div><div style="font-family: 'Helvetica Neue', 'Segoe UI',
Helvetica, Arial, 'Lucida Grande', sans-serif;"><br clear="none"></div><div style="font-family: 'Helvetica Neue', 'Segoe UI', Helvetica, Arial, 'Lucida Grande', sans-serif;">Absent a pressure test to 150% of MAOP everyone should assume that eventually there will be a rupture failure, and if that failure occurs in the GTA the cost will be many billions of dollars. Enbridge is a large company but I doubt its capacity to fund a $10 billion to $20 billion spill clean up. Hence Enbridge should carry third party insurance of $10 billion to $20 billion per incident. If Enbridge has to choose between properly fixing the pipe and paying the insurance premium on a $20 billion policy it will probably choose to fix the pipe, which is what it should have done in the first place.</div><div style="font-family: 'Helvetica Neue', 'Segoe UI', Helvetica, Arial, 'Lucida Grande', sans-serif;">Best Regards,</div><div style="font-family: 'Helvetica Neue',
