The guidelines were developed by the Pipelines and Informed Planning Alliance (PIPA). The report, <i>Partnering to Further Enhance Pipeline Safety in Communities through Risk-Informed Land Use Planning, </i>offers recommended safety practices. The planning document also talks about damage to pipelines from roots. Follow the link and check out Appendix ‘C’, examples 14 and 15 (a)-(f); you may find this informative. I was particularly intrigued by the lighting damage aspect, which I would not have considered, given that southern coastal areas of British Columbia suffers few lighting strikes to trees.<b><o:p></o:p></b></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><a href="http://primis.phmsa.dot.gov/comm/publications/PIPA/PIPA-Report-Final-20101117.pdf#pagemode=bookmarks">http://primis.phmsa.dot.gov/comm/publications/PIPA/PIPA-Report-Final-20101117.pdf#pagemode=bookmarks</a><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>Owen Croy, City of Surrey<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal style='margin:0cm;margin-bottom:.0001pt'><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> canufnet-bounces@list.web.net [mailto:canufnet-bounces@list.web.net] <b>On Behalf Of </b>Ray Morgan<br><b>Sent:</b> November-23-11 7:41 AM<br><b>To:</b> canufnet@list.web.net<br><b>Subject:</b> [CANUFNET] Fwd: Roots causing damage to Gas and Oil pipelines<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal style='margin:0cm;margin-bottom:.0001pt'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <o:p></o:p></span></p></div><div><p class=MsoNormal style='margin:0cm;margin-bottom:.0001pt'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>As per the subject line, I just came back from a meeting with a high profile oil company on how roots of trees/shrubs are decaying/corroding the protective coating on oil and gas pipe lines.<o:p></o:p></span></p></div><div><p class=MsoNormal style='margin:0cm;margin-bottom:.0001pt'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>They are saying that because of the moisture content that surrounds the pipes, roots are attracted to this and are now "wrapping" themselves around the lines.
