3.0 PIPELINE CONSTRUCTION i The following sections describe various important aspects of pipeline construction, including general pipeline construction practices, environmental protection measures, pipeline installation details, and reclamation/revegetation methods. 3.1 General Pipeline Construction Practices 3.1.1 Preconstruction Requirements American Soda will conduct a scheduled preconstruction conference prior to commencing construction and/or surface-disturbing activities on the ROW. The contractor or agents involved with construction and/or any surface-disturbing activities associated with the ROW will also attend this conference to review the construction stipulations, including the Plan. of Development. American Soda will provide maps or survey plats of this project to operators of all pipelines to be crossed or paralleled by the Yankee Gulch Project pipelines (e.g. Barrett Resources, CIG, Northwest Pipeline Company). Determining the names and contacts for these operators will be the responsibility of American Soda. American Soda will certify that these contacts have been made and the required information given if requested by the BLM. In addition, American Soda will notify all utility companies (via the One-Call system or similaz utility notification system) with e~dsting utility lines in the viciruty of the project, for field marking prior to commencement of construction. 3.1.2 Pipeline Construction Logistics Construction will likely be divided into three general azeas or "spreads" along the pipeline. The number of spreads could change based on construction timing limitations and/or the contractor's schedule, the actual spread boundaries could vary according to contractor work plans and responses to weather and environmentally acceptable construction periods. Likely laydown areas (areas used to set up equipment and temporarily store pipe) aze shown on Figure 2-2. Two laydown azeas will likely be required neaz Davis Point due to the stringent construction constraints at this location. Additional laydown areas may also be required, depending on available access. Preliminary construction work components are listed in Table ~1. Centerline surveys, which will be completed in the summer of 1999, and detailed pipeline design may result in variations in these quantities. Construction of the spreads may occur individually or concurrently, with an • anticipated total of 025 to OS mile of pipeline completed per day across each n~ r~„ of oNdop~,mt g Yankre Guld~ Sadie Maxrak Roject Aa~n Soda, LLP.
