Environmental Due Diligence - Consultant

Subsurface as-built verification for solar field. BDI was contracted by Delta Oaks Group (DOG), Environmental Resources Management (ERM), and Dominion Energy to investigate a former landfill in Montrose, Virginia. The project team needed to better understand the extent and depth of a landfill cover that had been installed in 1978, despite the absence of historical construction records, site plans, or geotechnical documentation. To support future development and engineering planning, the BDI NDE team performed a comprehensive Ground Penetrating Radar (GPR) investigation across approximately 934,000 square feet of the site. Using a survey-grade, GPS-enabled GPR system, the team collected more than 5.3 miles of subsurface data along a 50-foot by 50-foot testing grid, providing detailed coverage of the project area. Because little information was available regarding the landfill's construction, BDI evaluated areas both inside and outside the anticipated landfill boundaries. By comparing subsurface characteristics, the team developed a model that distinguished landfill materials from native soils and allowed for accurate interpretation of the landfill limits. BDI also identified high-amplitude subsurface anomalies that may indicate concentrations of buried landfill debris. The investigation enabled BDI to estimate and develop as-built information for the landfill, including the extent and depth of the landfill cover. To make the results easily accessible in the field, BDI converted the findings into a GPS-enabled Google Earth KML file, allowing project stakeholders to visualize landfill boundaries and subsurface features in real time.

Grid delays and planning gaps top agenda at Onshore Wind 2026 as sector demands policy certainty. Home / Blog / News / Grid delays and planning gaps top agenda at Onshore Wind 2026 as sector demands policy certainty. Emily Burn August 29, 2026 0 Comments Onshore wind policy certainty is the defining demand heading into ERM's co-hosted Onshore Wind Conference 2026, with developers, lawyers and asset owners converging on Edinburgh to press the case that grid constraints, consenting delays and unclear market signals are now the primary brake on deployment, not the technology itself. The conference, co-hosted by RenewableUK and Scottish Renewables on 1-2 September, will take place at the EICC Edinburgh. According to RenewableUK, over 1,000 attendees and 60 exhibitors are expected, numbers that put the scale of the sector's mobilisation in sharp relief against the policy gaps it is still trying to close. What industry voices are actually saying about onshore wind policy certainty. Scottish Renewables chief executive Angela Hepworth has set out perhaps the sharpest framing of the moment. The Strategic Spatial Energy Plan, she argues, 'must provide a clear trajectory beyond 2030 that supports Scotland's onshore wind opportunity and gives confidence in both new development and its existing fleet.' That is a pointed request: not a vague call for ambition, but a demand for a dated, legible pathway that developers can price against. Hepworth's case rests on a foundation worth stating plainly. Scotland already has more than 10GW of onshore wind operating, supporting more than 16,000 jobs. The argument is not that the sector needs to be built; it is that a sector already at scale is being held back by policy misalignment across planning, grid, charging and market frameworks. Shoosmiths legal director for energy and infrastructure Jacques Camilleri echoes the grid concern without softening it. Scotland has a significant pipeline capable of supporting further growth, he notes, but grid constraints, connection delays and wider market challenges continue to limit its potential. His warning to developers is operational as much as political: 'Developers must increasingly align construction programmes with evolving grid connection requirements, while ensuring projects remain commercially viable as procurement, financing and delivery requirements evolve.' That is a polite way of saying the goalposts keep moving, and someone has to absorb the cost. Vattenfall UK head of onshore wind market development Matt Bacon adds transmission infrastructure, faster consenting and clear market signals to the list of requirements. In a Q&A for the conference's show daily, he describes the UK as entering a new phase of onshore wind growth, with activity expected to increase in England while Scotland works through its existing pipeline. Grid availability, network constraints, planning timelines and radar interference are, in his view, the four biggest delivery challenges currently. His prescription: stable allocation rounds, clear policy signals and a predictable investment environment. Nothing here is new in concept; the persistence of the ask is the point. Repowering moves from aspiration to operational reality. Alongside the new-build agenda, repowering is emerging as a concrete near-term opportunity across the UK's roughly 17GW onshore wind fleet. Nadara UK head of development Finley Becks-Phelps describes repowering as an important part of the sector's future pathway and a proven means of increasing output from some of the country's best wind sites. Those sites carry a structural advantage: they already have planning history, access roads and, in many cases, grid connections. The question is whether the consenting and commercial frameworks will allow developers to realise that advantage efficiently. ScottishPower Renewables has put a number on what repowering can look like at scale. The company has announced plans to repower Whitelee wind farm through a £1.5bn investment programme that could double top capacity to around 1GW+. Whitelee is already one of Europe's largest onshore wind farms; a doubling of capacity from an existing, consented site represents exactly the kind of low-friction deployment the sector says it needs more of. The broader message from the Edinburgh gathering is consistent: onshore wind policy certainty is not a political nicety but a commercial prerequisite. Investment decisions are being deferred, not cancelled, and the sector's argument is that the pipeline exists, the sites are known and the technology is ready. The Strategic Spatial Energy Plan's trajectory beyond 2030 will be the first real test of whether government has heard that case. Quick links.

PGW examines pathways to reduce emissions. Posted on: Jul 29, 2026 PGW is identifying potential decarbonization options to shape future energy decisions Philadelphia (July 29, 2026) - Philadelphia Gas Works (PGW) is dedicated to leading Philadelphia's clean energy future and is pursuing several different opportunities and initiatives to move the company and the City forward. One effort launched this year is PGW's Low Carbon Pathways project, aimed at exploring possible long-term decarbonization pathways while also prioritizing safety, affordability and reliability to advance decarbonization goals and support a cleaner, greener Philadelphia. To undertake important work, PGW engaged a leading sustainability consulting firm, Environmental Resources Management, Inc. (ERM), which was competitively selected by PGW to support analytical modeling and stakeholder engagement. "The goal of this study is to explore a range of viable options as representative examples for comparison, and to establish a foundation for future decision making," said Janelle Johnson-Grummert, PGW's Director of Sustainability. "As we drive sustainability efforts, we want to prioritize the greatest emission reductions possible while ensuring no customers are left behind and all have access to safe, reliable, and affordable energy." To continue reducing Greenhouse Gas Emissions (GHG) in Philadelphia, PGW has set annual emissions reductions targets since 2023, to meet its ambitious long-term goals. For its 2025 fiscal year (September to August), PGW's target reduction was 10,500 metric tons of carbon dioxide equivalent (CO2e) and PGW notably exceeded this target, achieving a total reduction of over 12,000 metric tons of CO2e. PGW currently accounts for approximately 21 percent of the City of Philadelphia's city-wide GHG emissions. While PGW's share of GHG emissions is less than transportation and electricity, the reductions PGW is making a meaningful step in achieving the City of Philadelphia's commitment to reach carbon neutrality by 2050. Led by ERM and PGW, the comprehensive analysis will look at outcomes from several scenarios, including: * PGW's current natural gas network and emission-reduction programs; * a hybrid, or mix of electric and gas systems; and * a shift away from natural gas towards more electricity usage for space heating, cooking, drying, and water heating. The Low Carbon Pathways Project study and will be completed in fall 2026. As part of the study PGW will host two virtual community engagement sessions to discuss and gather feedback from Philadelphians to help inform PGW's ongoing and future work.
