FEATURED PROJECT

EDM developed an APP and ARA for a large investor-owned utility with over 20,000 miles of distribution and transmission lines across a major metropolitan region with globally important bird habitat. A GIS-based analysis of bird use, habitat and infrastructure data identified target survey areas. Field biologists assessed dozens of avian and power line variables to determine avian electrocution and collision risk; for each hazardous structure or line span, EDM assigned a retrofit priority and developed a retrofitting approach. The deliverables provided short- and long-term planning tools for reducing avian risk and improving system reliability. Updated construction standards and training modules were developed to ensure the plans were fully implemented and reliability and conservation goals were achieved. Tailored communications materials were developed to facilitate company outreach among customers, regulators and employees.

FEATURED PROJECT

As a third-party designee under both NEPA and ESA, EDM analyzed potential impacts from a 115kV transmission line rebuild across multiple land jurisdictions with three federal oversight agencies. EDM navigated and facilitated complex interagency communications; assessed multi-disciplinary impacts across federal, state and private lands in a high-profile and biologically sensitive area; conducted an avian collision risk assessment across miles of a National Wildlife Refuge; implemented detailed wetlands analyses and mitigation planning; conducted pre-construction biological surveys; and managed construction and post-construction environmental monitoring. EDM’s specialized knowledge of avian risks and mitigation allayed agency concerns, substantially accelerating the permitting process and ultimately, project completion.

EDM’s technical specialists in wildlife, plants, wetlands, soils and surface waters conduct baseline studies to scope environmental issues, provide the framework for impact assessments and identify opportunities for avoidance or mitigation. EDM proactively identifies project-specific environmental issues early in the planning process and incorporates protection measures into the project description to streamline assessments, optimize timelines and minimize costs. Scaled to meet client goals, studies range from desktop GIS analyses to field-based habitat assessments, nest searches, or presence/absence surveys.

FEATURED PROJECT

On behalf of a small electric cooperative, EDM developed a 5-year Construction Work Plan (CWP) for existing and proposed power line rights-of-way (ROWs) on federal and private lands to prevent costly and disruptive permitting delays. EDM developed an interactive mapping tool incorporating utility infrastructure/ROWs and sensitive species/habitat data from multiple sources. The tool was used to: a) identify areas where sensitive species could interfere with planned construction and maintenance; b) identify opportunities to schedule work for seasons that would avoid or minimize potential impacts; and c) develop a realistic work schedule that allowed adequate time, where needed, for federal and state permitting. The CWP and associated report allowed the cooperative to optimize their schedule and planning, facilitated permitting by providing appropriate Best Management Practices to minimize or mitigate potential impacts, ensured regulatory compliance and clear agency communications and prevented project delays associated with environmental “surprises.”

EDM’s expertise in environmental permitting and compliance, avian overhead line studies and communication tower studies has facilitated the company’s expansion into wind facility review and assessment. The wind industry and U.S. Fish and Wildlife Service are encouraging wind developers to apply approaches and measures similar to those used in avian protection plans for electric utilities to prepare applicable protection plans for wind energy facilities to minimize potential effects to birds and bats and aid in complying with key federal legislation, including the MBTA, ESA, BGEPA and NEPA. EDM’s team has experience with the applicable federal, state, county and/or local permitting and compliance requirements that are becoming more integral to wind facility planning. Most importantly, EDM can provide insight for both short- and long-term project planning, encompassing regulatory knowledge, established and proven practices, standardized methods and metrics and proactive communications. EDM co-authored a detailed review of avian collision studies with communication towers for the FCC in 2004. EDM also has conducted post-construction bird collision studies to determine the potential long-term collision risk to birds from tower operation.

Applicable Experience Includes:

• Pre-Construction Screening
• Preliminary & Detailed Wildlife & Plant Baseline Studies
• Federal, State, & Local Permitting & Compliance

FEATURED PROJECT

Tasked with delineating priority structures for eagle-friendly electrical retrofits in a 12,000‑square-mile service territory, EDM modeled the region in GIS, using habitat, nesting and observational data to calculate the relative priority of each 30-meter grid cell. In an iterative process, features in each data layer were assigned positive or negative weights based on the scientific literature and EDM’s deep expertise in avian protection planning. Priority areas were smoothed and aggregated using nearest-neighbor techniques, generating minimum-sized polygons for field personnel and planners. Deliverables included identification of eagle priority areas and an ESRI model, facilitating improvements and updates as new data become available.

FEATURED PROJECT

The Bird Strike Indicator (BSI), developed by EDM, is an automated monitoring tool that detects and records bird strikes on overhead wires or guy wires, and transmits real time data to remote desktops. BSIs have been deployed throughout the U.S. (including Alaska) and in Europe, Africa and the Pacific Islands. Utility companies, permitting agencies, and industry researchers have used the BSI to identify high risk power line segments, evaluate collision risks to sensitive bird species, and determine the effectiveness of line marking devices. BSIs have been used to determine the need — or lack thereof — for both proactive and reactive line marking. The BSI recently was specified as NEPA-required mitigation for a new, high-profile transmission line bisecting a critical migration corridor.
