What health considerations are there?
Pipelines carry hazardous materials and therefore entail safety risks. Typically, natural gas pipeline accidents that cause explosions and/or fires are most frequently due to excavation and pipeline corrosion or defects. 1 According to PHMSA, from 2004 to 2013, the ten-year incident average for natural gas pipelines was as follows: 117 incidents on transmission lines; 16 on gathering lines (rural gathering lines do not require incident reporting) 2; and 137 on distribution lines. 3
