Poster | Creative and Collaborative Mitigation at the Neil R. Underwood Bridge
About the Poster |
The New Hampshire Department of Transportation (NHDOT) and its design team worked together with multiple federal and state agencies and the University of New Hampshire Sea Grant to develop a creative and effective mitigation strategy for the needed replacement of the Neil R. Underwood Bridge (NH Route 1A). The bridge is located on an ecologically sensitive site along Hampton Harbor and is a vital transportation link between Hampton Beach in the north and Seabrook in the south. It also accommodates tourist traffic from southern New England. Robust coordination with federal and state natural resources agencies guided and informed the project from early planning through detailed design and construction. As a result of this effective coordination, the project is successfully achieving critical transportation objectives while also conserving important natural resources. Coordination with the New Hampshire Natural Heritage Bureau (NHNHB) at the outset of the project identified the adjacent dune habitat as a Highest Ranked Habitat in New Hampshire. Subsequent detailed field surveys identified and mapped six plant species listed as threatened or endangered in the State of New Hampshire occurring in the adjacent dune habitat. Early consultation with the US Fish and Wildlife Service (USFWS) also identified habitat for the federally endangered Piping Plover on the beach adjacent to the bridge, which informed the bridge's alignment. The consultation with USFWS resulted in a Biological Opinion and a series of conservation and mitigation measures that NHDOT is following. As the project advanced from planning into final design, a Mitigation Plan was developed in concert with NHNHB which specified a range of techniques to address anticipated unavoidable impacts to the rare plants. Woody and clumpy listed plant species were hand-relocated and transplanted to adjacent suitable habitat areas outside the footprint of the new bridge approach. For annual and non-clumpy species that couldn't be effectively hand-transplanted, surface sand material containing seed stock was stripped from dune habitat within the impact footprint and evenly re-dispersed outside of the project limits via aerial dispersal methods. To further support the re-establishment of these species, NHDOT, through the New Hampshire Sea Grant, collected seeds from existing plant species prior to relocation. The seed stock will be used to propagate seedlings for future transplant onto the site. Once construction is complete in 2028, the side slopes along the southern approach will be revegetated with locally sourced beachgrass plugs, rather than standard turf establishment methods and materials. It is anticipated that over time the side slopes will begin to re-establish with state-listed plant species and provide priority dune habitat into the future. |

Poster | Environmental Justice in the Reimagine I-787 PEL Study
About the Poster |
Interstate 787 (I-787) and the South Mall Expressway, constructed in the 1960s and 70s in Albany, New York, are essential components of the region's transportation network. However, their presence has substantially affected local communities, particularly those identified as environmental justice populations. The overbuilt nature of I-787 (it includes multiple connections to a planned highway network that was never constructed), along with adjacent railroad infrastructure, has obstructed access to the Hudson River waterfront, limiting residents' engagement with this vital natural and recreational resource.The New York State Department of Transportation (NYSDOT) is currently conducting the Reimagine I-787 Planning and Environment Linkages (PEL) Study. This initiative explores strategies for better integrating transportation infrastructure into the urban fabric of Albany, including potential reconstruction or replacement of the interstate, improved access to the waterfront, enhanced bicycle and pedestrian facilities, and greater neighborhood connectivity.Integral to the PEL process and environmental justice is the active engagement of the public. NYSDOT has prioritized public participation to ensure that all perspectives are reflected in the planning process. This poster will provide an overview of the high-level EJ study conducted within the PEL process, then focus on efforts and methods used to engage with environmental justice populations. |

Poster | Microplastics Monitoring, Risk Assessment, and Management in the Great Lakes
About the Poster |
The rapid rise in the production and use of plastics over the past century, coupled with unsustainable waste management practices, has led to widespread plastic pollution including the ubiquity of microplastics across the globe. Microplastics are small plastic particles, often defined as ranging in size from 1 μm to 5 mm, that originate from the wear and tear of plastics during use (e.g., clothing, tires, paint), from the breakdown of discarded plastic products in the environment, and from industrial and other sources. Research has shown that microplastics are present in many global environments and can have adverse health effects on aquatic organisms. Potomac-Hudson Engineering, Inc. (PHE) in partnership with LimnoTech, recently completed a project for the International Joint Commission (IJC)'s Science Advisory Board that focused on microplastic pollution in the Great Lakes. The project focused on water quality in both Canadian and U.S. water of the Great Lakes, and was guided by a group of experts from both countries. The project was informed by, and included collaboration with, similar microplastics programs that are taking place in Southern California and the Chesapeake Bay.
This project sought to synthesize recent advances in microplastic knowledge including environmental occurrence and ecological risk, and develop separate but coordinated microplastics monitoring and risk management frameworks. Key aspects of the project included an in-depth literature review and data mining effort, two expert workshops focused on microplastics monitoring and risk assessment, and a final summary report with recommendations on next steps. Note that the risk assessment phase of this project focused primarily on ecological risk, with the hope that future efforts will look into human health risks posed by microplastics in the Great Lakes.
Join PHE and LimnoTech as we discuss the key findings and outcomes of this effort, which will include:
- Background on microplastics, including sources and characteristics
- Summary of microplastics occurrence data in the Great Lakes.
- Discussion of ecological risks of microplastics and the current state of knowledge, focusing on microplastics risks to freshwater aquatic organisms.
- Summary of workshop outcomes, which included a set of SOPs for environmental sampling of microplastics and preliminary guidelines and a framework for the risk assessment and management of microplastics in the Great Lakes.
- Recommendations generated by the project, including establishing a monitoring program focused on microplastics, more ecotoxicological studies on species relevant to the Great Lakes, and the inclusion of microplastics into existing management frameworks aimed at contaminants of concern in the Great Lakes region.

Poster | Phytoremediation Potential of Chromolaena Odorata in Soils Polluted with Heavy Metals and Radionuclides
About the Poster |
Heavy metals and Radionuclides are quarry pollutants produced during the crushing of rocks and have been reported to cause severe health effects in the environment. This study assessed the phytoremediation potential of Chromolaena odorata in soils polluted with heavy metals and radionuclides from quarry site in Ibadan, Oyo state. Soil samples were collected in triplicates from ten sampling points in the quarry site and control. Soil samples were put in thirty pots and Chromolaena odorata were planted in each pot and allowed to grow for 10 weeks. Physical and chemical parameters such as pH, electrical conductivity (EC), organic carbon (OC), organic matter (OM), exchangeable bases (Ca, Mg, Na, K), and particle size were determined in soil samples using standard methods. The soil and plant samples were digested for heavy metals (Al, As, Co, Cd, Cr, Cu, Fe, Hg, Mn, Mo, Pb, Sb, Se, Sn, V, and Zn ) and radionuclides ( 238U, 232Th, and 40K) using standard procedures and quantified using Inductively Coupled Plasma- Optical Emission Spectrometry)- (ICP-OES) and Gamma-ray Spectroscopy Coupled NaI Detector. Bioaccumulation factor (BCF), reduction percentage, and accumulation ratio were determined. Health risk assessments were estimated for radionuclides vis-a-vis external hazard index, internal hazard index, excess lifetime cancer risk (ELCR) and for metals hazard quotient (HQ), hazard index (HI) and cancer risk (CR). Data obtained were subjected to descriptive (Mean ±SD) and inferential (Anova) statistics. Results showed that mean value of pH ranged from 7.46±0.01 to 7.94±0.01, which was slightly alkaline and higher than control value (7.06±0.01) before phytoremediation. After phytoremediation, pH values ranged from slightly acidic (5.86±0.08) to slightly alkaline (7.39±0.03) and control had highest value (7.91±0.00). Particle size distribution showed that the soils samples were sandy in nature and ranged from 86.00±0.00 to 96.00±0.00 (%) before phytoremediation. After phytoremediation, there were increases in percent sand and clay at some sampling points. The values of physical and chemical parameters in soils were within the WHO permissible limit. The concentrations of heavy metals and radionuclides detected in soils were within the WHO allowable limits, except for 232Th (30 Bq/kg) and 40K (400 Bg/kg) which were slightly higher than the permissible limit before phytoremediation. The BCF results was greater than one indicating phytostabilization of heavy metals by plants. The health risk assessment values revealed that ELCR was higher in almost all the sampling points before phytoremediation than the recommended value of 2.9×10-4 implying a risk of cancer development due to radionuclides in the location. The CR (ingestion) of Cr (1.97×10-1) for adults was also higher than the USEPA limit. This study revealed that Chromolaena odorata could be used to phytoremediate heavy metals and radionuclides in quarry sites. |

Poster | Residential Energy Coaching: Scalable Solutions for Community Energy Efficiency
About the Poster |
With residential energy use exceeding 20% of the United States' total consumption, according to the Environmental Information Administration, there is a pressing need for community-driven solutions to reduce demand and accelerate the transition to sustainable, electrified systems. In response, a Residential Energy Coaching Program arose from the University of Michigan's Graham Sustainability Institute in collaboration with the GreenHome Institute and the municipal utility, Traverse City Light & Power. This program supports residents in making energy-efficient upgrades and electrifying home systems, empowering communities to achieve meaningful reductions in energy costs and environmental impact.
The Residential Energy Coaching Program offers residents a one-stop, accessible solution that connects them with trained energy coaches who serve as trusted advisors. These coaches provide personalized guidance on a wide range of topics, from appliance electrification and insulation improvements to renewable energy options and energy management strategies. Importantly, they also inform residents about financial incentive programs, tax credits, and rebates available to help them make informed decisions and reduce upfront costs as much as possible. Through customized, practical recommendations, residents can confidently implement changes that lead to substantial energy savings, lower utility bills, and reduced carbon footprints. This holistic approach to energy coaching is tailored to meet the unique needs of each household, fostering a culture of sustainability and resilience within the community.
This session will delve into the practical framework, resources, and tools developed to make residential energy coaching accessible and effective. Attendees will gain insights into engagement strategies, communication approaches, and the logistical considerations of rolling out a community-focused program. A key component of the session will be an introduction to the Residential Energy Coaching Guidebook and a program template, both designed to be easily adapted by other communities. These resources provide step-by-step guidance on establishing, promoting, and managing a local energy coaching program, allowing communities to replicate this model and support residents in adopting sustainable practices.
Participants will also explore the program's broader impacts, including enhanced resident awareness, energy cost reductions, and contributions toward community climate goals. By bringing together technical guidance, individualized coaching, and community outreach, this initiative represents a scalable model that advances local climate action and energy equity.
Led by Yuk Long Yip, a Catalyst Leadership Circle Fellow under the University of Michigan's Graham Sustainability Institute, this session will highlight the benefits of the program not only at the community level but also for utilities. Attendees will be equipped with a replicable, sharable toolkit and an understanding of how to launch and sustain a successful residential energy coaching program, ultimately fostering climate resilience and a more sustainable energy future at the grassroots and utility level.

Poster | Resource Management Plan Amendment for Big Game Habitat in Colorado
About the Poster |
Colorado's iconic big game species, including bighorn sheep, elk, mule deer, and pronghorn, are important to natural systems, hunting and wildlife viewing enthusiasts, and local economies. Some local populations of these big game species have suffered declines in recent decades. In a first-of-its-kind effort, the US Department of Interior, Bureau of Land Management (BLM), Colorado State Office prepared an amendment to its land use plans to promote the conservation of big game corridors. Specifically, the BLM incorporated new oil and gas lease stipulations and adopted additional measures to enhance protection for high-priority habitat areas for elk, mule deer, pronghorn, and bighorn sheep. High-priority habitat areas for these species include migration and movement corridors, production areas, severe winter ranges, winter concentration areas, and winter ranges, depending on the species. The plan amendment aligned with the Colorado Energy and Carbon Management Commission's rules for oil and gas development in elk, mule deer, pronghorn, and bighorn sheep high priority habitats. Under the plan amendment, authorization of new oil and gas facility locations on BLM-managed lands within big game high-priority habitats will be avoided when the oil and gas location density exceeds one active oil and gas location per square mile or contributes to an increased density beyond one active oil and gas location per square mile.
In addition, the BLM will require a Wildlife Mitigation Plan for operators with new oil and gas facility locations within big game high-priority habitats. The Wildlife Mitigation Plan will address direct and indirect functional habitat loss. The analysis in the environmental impact statement for the plan amendment was similarly unique, including an oil and gas emissions inventory and evaluation of existing disturbances and their densities within big game high-priority habitats. The oil and gas emissions inventory included criteria air pollutants, volatile organic compounds, hazardous air pollutants, and greenhouse gases. The BLM modeled predicted emissions from each type of air pollutant under each alternative. The plan amendment would result in a decrease in criteria air pollutants in Colorado. Further, the BLM calculated the social costs of greenhouse gases by alternative. Under the plan amendment, the social costs of greenhouse gases are expected to be over 11 percent lower than under existing conditions.
The evaluation of the existing disturbance included calculations of current anthropogenic, oil and gas, and renewable energy disturbances by big game species. The environmental impact statement also presented existing oil and gas, road, and trail densities by species in high-priority habitat areas. The BLM concluded that the new oil and gas lease stipulations and additional protections would reduce impacts on big game, such as habitat fragmentation, mortality, injury, or displacement.
