In its pure state, natural gas has no smell, colour or taste. EPCOR will be adding Methyl Mercaptan to make it smell like Sulphur or rotten eggs. Natural gas is a safe and reliable fuel source so leaks are rare but adding this odorant makes it easier to detect a leak, if it occurs. Once the pipeline is in service, EPCOR will continue odorant monitoring to ensure this odour is detectable throughout the system. Please notify EPCOR immediately if you smell Sulphur or rotten eggs in the area. The phone number is 1-888-765-2256.
