The\r\npipeline crosses three major rivers between the Alpine Development CD1 facility and its tiein\r\nto the Kuparuk Pipeline. These three river crossings include the horizontal directionally\r\ndrilled (HDD) crossing of the East Channel of the Colville River; and the two aboveground\r\ncrossings of the Kachemach River and the Miluveach River.\r\nMonitoring of the HDD crossing was first conducted in 2001 (Baker 2002). From 2003 through\r\n2006, annual monitoring of the HDD, Kachemach River, and the Miluveach River crossings\r\nwas conducted (Baker 2003, 2004, 2005, 2006). Over the course of the previous five years\u2019\r\nmonitoring events, no significant scour, erosion, or VSM tilt were observed at the Kachemach\r\nand Miluveach River crossings. As a result, in the fall of 2006 a five-year monitoring interval\r\nwas recommended. Therefore, in 2007, monitoring was limited to the HDD crossing (Baker\r\n2007).\r\nThe 2008 monitoring, including surveying by Kuukpik/LCMF, LLC (LCMF), was conducted\r\nat all three crossing locations (Baker 2008). In 2009, LCMF surveying was conducted only at\r\nthe HDD crossing location. Visual observations and tilt measurements were conducted at all\r\nthree locations. It is anticipated that LCMF will continue to provide annual bank erosion\r\nsurvey data for the HDD crossing, and that bank erosion surveying of the Kachemach and\r\nMiluveach will occur again in 2013.\r\nMonitoring is conducted to document the condition of the pipelines and channel morphology\r\nat each of the river crossings. Monitoring also allows for a comparison between observed\r\nconditions and the design criteria, as required by Right-of-Way Lease/Grant Stipulations and\r\nthe Alpine Surveillance and Monitoring Program. The primary objective is documentation of\r\nthe state of the pipeline at each crossing, as well each pipeline\u2019s affect on the channel.", "end_date": "2008-08-30", "title": "Alpine Pipeline River Crossing 2009 Monitoring Report", "other_contacts": [], "iso_topics": [], "tags": ["Apline Pipeline", "ABR", "river crossings", "Colville River", "alaska"], "bounds": [{"geom": "{\"type\":\"Polygon\",\"coordinates\":[[[-152.2636032795796,70.03291021370266],[-150.1884710840829,70.03291021370266],[-150.1884710840829,70.50993159770778],[-152.2636032795796,70.50993159770778],[-152.2636032795796,70.03291021370266]]]}", "type": "Attachment"}], "start_date": "2008-04-01", "regions": [], "other_agencies": "ConocoPhillips", "data_types": [], "archived_at": null, "primary_contacts": [], "type": {"color": "#3a87ad", "name": "Data", "description": "catalog record for projects with associated data/observation files"}, "slug": "alpine-pipeline-river-crossing-2009-monitoring-report", "attachments": [{"category": "Geojson", "file_name": "imported_locations", "description": "gLynx locations", "file_size": 4201}, {"category": "Public Download", "file_name": "FINAL 2009 Pipeline Monitoring_09_23_09(117009-001).pdf", "description": "", "file_size": 6983958}]}
