Other Services
Environmental Services
Wilson Construction Company’s environmental division specializes in environmental compliance management as it relates directly to the utility construction industry. Our team brings expertise to construction projects in the areas of mitigation planning; permitting; Storm Water Pollution Prevention Plan (SWPPP) development and implementation, inspection and monitoring; erosion and sediment control; and restoration and environmental training.
Wilson Construction works proactively toward ensuring successful work operations with minimal impact on the environment. By making sure our workforce is conscious of the environmental issues on every job we perform, and by stressing minimal disturbance as part of our work policy, projects are completed successfully with as little disturbance as possible. Our environmental planning starts as early as the bid process ensuring that the environment is considered in how we will perform the work.
Our Capabilities Include:
Environmental Mitigation Planning and Implementation
Many projects have some element of environmental mitigation that is required. We can help you develop a mitigation plan that details how to protect the resources on your project during construction. Our team has experience dealing with a wide variety of environmental issues, including but not limited to, protected animal and plant species and their habitats, aquatic resources, including wetlands and vernal pools, and cultural resources.
Environmental Compliance Management and Inspection
-
Oversight of project environmental requirements
-
Inspection, monitoring and reporting of implementation of Best Management Practices
-
Technical review of pre-construction documents (i.e. permits, technical specifications, etc.)
Erosion and Sediment Control
Construction projects have the potential to expose large areas of soil which increase the risk for soil erosion and sediment-laden storm water run-off. Wilson Construction can develop and/or implement a Storm Water Pollution Prevention Plan for you. Our team will design, install and maintain your temporary and permanent erosion and sediment control Best Management Practices (BMP's) throughout the construction of your project.
Environmental Training
Wilson Construction Company will develop a training program specific to your project and train your personnel. Possible training topics include:
- Spill response
- Best Management Practice (BMP) installation
- Environmental protocols
- Cultural resource protection
- Noxious weed management
Restoration Planning and Implementation
Wilson Construction Company offers complete restoration services that include reclamation and revegetation.
Projects Examples
Ebey Slough Transmission Line Rebuild Project, WA
This project involved removing and rebuilding a 2-mile portion of two single-circuit transmission lines to double-circuit. The existing lines were in a tidally-influenced, partially-inundated wetland and were rebuilt within the existing ROW. Specialized equipment was used to construct micropile foundations and move materials from site to site within the wetlands. Multiple permits were obtained to work in wetlands; daily monitoring and inspections were performed to monitor turbidity and dissolved oxygen. Wilson developed a Storm Water Pollution Prevention Plan (SWPPP) for the project and was responsible for implementation. Erosion and sediment controls were installed in the wetland to contain turbid water and keep discharges from occurring. Construction operations (i.e. micropile drilling, grouting, concrete operations, tower erection & pulling wire) were carefully planned to keep impacts to wetlands minimized. Tower removal occur once the new structures are in place and restoration to wetlands began.
McNary to John Day 500kV Transmission Line Ph I, and II, OR
This transmission line project entailed building a brand new 500kV double-circuit line from the McNary Substation in Umatilla, Oregon to the John Day Substation in Rufus, Oregon. The project consisted of 371 new structures, over 77 miles of new transmission line, 20 miles of new spur roads along with over 70 miles of existing road upgrades. Wilson Construction was responsible for implementing the BPA issued Stormwater Pollution Prevention Plan (SWPPP), installing and maintaining BMPs for the project, and coordinating construction activities with the Umatilla Tribe, Yakima Tribe, US Army Corp of Engineers (USACOE) and land owners. Wilson’s environmental personnel were also responsible for controlling the spread of noxious weeds, protecting sensitive areas from disturbance, minimizing impacts to agricultural crops, and conducting restoration of 285 acres that were disturbed during construction activities.
Before After
Tehachapi Renewable Transmission Project (TRTP) Segments 7 and 8, CA
Segments 7 and 8 of the Tehachapi Renewable Transmission Project (TRTP) includes construction of approximately 49 miles of double-circuit 500kV and seven miles of 220kV transmission line through highly urban, as well as undeveloped open spaces in California’s Los Angeles and San Bernardino Counties. Wilson’s on-site team of environmental professionals manages the challenging constraints of the project and works directly with construction crews to ensure compliance with the project’s numerous mitigation measures. Wilson implements four Stormwater Pollution Prevention Plans (SWPPPs) by performing daily inspections, installing and maintaining BMPs, and performing site restoration. Mitigation measures for the protection of migratory, threatened, and endangered bird species are successfully implemented; impacts to construction are managed by tracking bird nests and through the employment of a rigorous bird deterrent program.
Walla Walla-Tucannon & Bandon-Rogue-Dayton Tap Wood Pole Replacement, OR and WA
This transmission line project, located along the pristine Southern Oregon Coast, consisted of 47 miles of 115kV wood pole replacement and reconductoring. The project traversed through many environmentally sensitive areas including wetlands, stream crossings, and a state park. Wilson Construction was successful in minimizing the project impact on the local environment by recognizing these sensitive areas and adjusting the footprint accordingly. The project was finalized with zero water quality violations and even less wetland disturbance than what was originally permitted. Construction was completed and the line was energized in January of 2012.
OnLine Project (Robinson Summit Substation), NV
Robinson Summit Substation will be a new 525/345kV substation located approximately 18 miles northwest of Ely, Nevada. Wilson Construction’s environmental division developed the Stormwater Pollution Prevention Plan (SWPPP) and the fugitive dust control plan for this project. During construction, Wilson will be responsible for conducting routine stormwater inspections, updating and amending the SWPPP, installing and maintaining erosion and sediment control BMPs, restricting the spread of noxious weeds, and controlling fugitive dust. Upon completion of the work, Wilson teams will restore any disturbed areas outside the substation footprint.
