infrastructure improved to meet future energy needs

CapX2020, a joint initiative of 11 transmission-owning utilities in Minnesota and the surrounding region, was formed to expand the power grid and help ensure continued reliable and affordable electricity. Barr has worked on three of the five transmission lines that make up the CapX system, including a line constructed by Xcel Energy that stretches from Fargo, North Dakota, to Monticello, Minnesota. Our services on this segment included overall management of the construction environmental-control plan, as well as preparation of a stormwater pollution-prevention plan (SWPPP) and applications for water-appropriations and construction-stormwater permits.

Barr developed protocols for SWPPP implementation, permitting, organic-farm review, pavement assessment, vegetation clearing and management, pollution prevention, work near wetlands and in public waters, work on steep slopes and highly erodible soils, and work near impaired waters. We also created best management practices and forms for conducting inspections, maintaining compliance with permit requirements, and protecting waters of the state adjacent to the construction area.

To streamline tracking and completion of numerous environmental activities, we created an electronic database and reporting system that allows access to real-time information via a secure website. The system houses all inspection forms and instructions for correcting accidental environmental infractions, and enables instant report generation. For each of more than 800 transmission poles, Barr prepared site maps and GIS figures and incorporated them into the database. The system, which organizes and links thousands of documents, makes information quickly and easily accessible to Xcel, the multiple parties involved in construction, and regulators. Field staff carry iPads with which they can view a satellite image superimposed by comprehensive site data—pole location, wetland boundaries, mitigation measures—and make updates that are instantaneously available to everyone using the system. 

The Fargo-to-Monticello line began delivering electricity in May 2015.
