Flowlines are subject to thorough inspections and fabrication standards during installation to minimize coating and pipe defects. Crestone maintains a chemical program to reduce internal corrosion. If a flowline is found to lack integrity, Crestone will investigate, report, and remediate any spills in accordance with the 900 series rules. Description of Integrity Management Program Crestone flowlines are pressure tested prior to placing flowlines into service. Flowlines are tested on an annual basis in accordance with COGCC 1104 series rules. If a flowline is found to lack integrity, Crestone will investigate the root cause, as well as report and remediate any spills in accordance with the 900 series rules. All repairs will be completed in accordance with COGCC 1102 Series rules. Description of the construction method used for public by-ways, road crossings, sensitive wildlife habitats, sensitive areas, and natural and manmade watercourses (i.e., open trench, bored and cased, or bored only), if applicable.
