A Phase I ESA is completed to research the current and historical uses of a property as part of a real estate transaction or sometimes a commercial property refinance. The intent of the Phase I ESA process is to assess if current or historical property uses have impacted the soil or groundwater beneath the property and could pose a threat to the environment and/or human health. For this presentation, my goal is to provide an overview of the Phase I ESA process for those consultants just beginning their careers, or provide a refresher for those who haven't performed Phase I ESAs recently. I will also discuss how the Phase I ESA works within the NEPA process as a supplemental study.

The success or failure of river basin organization (RBO), when they deal with disputes, might rely on the source of conflict along with other factors such as institutional design, legal attributes and conflict resolution mechanism of the organization. However, little attention has been paid to the research which studies a direct causal relationship between the source of the water conflicts and how those disputes were addressed by RBOs. This paper analyzed the impact of the sources of conflict on the success or failure of RBOs when dealing with disputes over shared water resources. Moreover, it also attempted to identify which source is the most difficult to handle for RBOs. The conflict resolution framework of Erik Mostert (Mostert, 1998) was chosen as the conceptual model while the literature review and statistical analysis were the main methods for this analysis. Initially, the Analysis of Variance (ANOVA) was applied to examine whether the source of the water disputes might influence how RBOs successfully handle those conflicts or not. Furthermore, the contrasts test was carried out to identify the most intense source of the conflict which is the most difficult to address for RBOs. The statistical analysis suggested that the intensity of the conflict may differ depending on the source of disputes and the conflicts related to infrastructure / development are the most difficult to handle for RBOs.

Market problem: Road transport is among the fastest-growing sectors, accounting for at least 80% of the global increase in diesel consumption and nearly one-third of the global transportation sector's CO2 emissions. In the United States, the transportation sector is now the largest source of greenhouse gas emissions, with medium- and heavy-duty vehicles used for freight among the most significant contributors. Early-stage electrification plans and proposed market solutions for essential and heavily trafficked domestic freight corridors in the United States have not been optimized around important factors.

INF and its partner ecosystem believe plans for zero-emission charging infrastructure that will meet ambitious federal and state energy goals must account for these factors to produce viable market solutions that will enable widespread adoption by producing the greatest co-benefits for road transport stakeholders. Proposed market solution - the best solution isn't always the fastest charging scenario: INF and its partner ecosystem are developing market solutions for medium and heavy-duty truck charging which optimize for current regulations that specify truck driver hours-of-service requirements i.e. when and how long drivers are allowed to drive by placing specific limits on the amount of time they drive the truck and how many total hours they can work before they are no longer permitted to drive a commercial motor vehicle. Enabling truck depots to function as microgrids by optimizing the charging rate around the driver's hours-of-service requirements carries significant co-benefits. Evergreen Charing System - a win for investors, utilities, freight industry, and the planet.

The proposed Evergreen Charging System is one emerging example that addresses the factors named above by providing an agile interconnected freight microgrid solution that: maximizes reliability and profitability of freight charging requirements; optimizes the total federal and private cost of infrastructure to build out a unified, national-level solution; and minimizes the number and complexity of permits and utility interconnections. Product ecosystem strategy and next steps: INF is a leading installer and support contractor of electric vehicle supply equipment (EVSE) and cloud infrastructure. We seek to use our deep knowledge of freight industry's real-world problems and our immense supply chain network to identify technical partners, anchor investors, and private joint venture opportunities to support validation and piloting of technologies that will support the buildout of a reliable, interoperable interstate network of truck depots.

Preparing permitting proposals or permitting applications quickly can be challenging for quickly reviewing all the potential constraints and permitting requirements across multiple agencies and jurisdictions. Terracon Consultants' environmental planners leverage Pivvot and ArcGIS Pro for project planning and permitting proposals. Leveraging these solution partners streamlines proposal preparation and generates site-specific permitting requirements. Additionally, project data is easily exported to ArcGIS Pro to generate report graphics and maps and to conduct deep dive analysis to support proposals' needs and the project lifecycle. This high-level overview of National Environmental Policy Act (NEPA) components helps planners quickly integrate requirements into proposals, estimate project costs more concisely, and identify project constraints and assumptions. These solutions help project planners and clients quickly understand the cost and timelines associated with potential projects, streamlining the proposal process, and clarifying project feasibility.Key Points: Quick turnaround, high-level review; data exports for mapping and analysis, and project cost estimation.

A redevelopment housing project tasked with the construction of over 300 single-family homes found itself in need of a technology that could quickly remediate building sites impacted with chlorinated pesticides historically applied to control termites. The scope was to excavate the foundation/dripline areas and stockpile those soils for subsequent sampling. 15,612 cubic yards were excavated, and roughly 6,244 cubic yards exceeded critical PCLs, requiring treatment. Of the 6,244 cubic yards above the residential PCL, some would have passed TCLP allowing it to be taken to a nearby Class II LF, but the rest would have likely required disposal as hazardous waste. The alternative of landfilling at a facility over 200 miles distant was grossly expensive and would produce an exponential carbon footprint when considering the effluent of exhaust by heavy-duty diesel truck engines. Added complications included the fact that the remediation phase had to be completed on schedule so as not to interfere with the pace of home building. Considering the evolution of chlorinated hydrocarbon remediation at the time, excavation appeared to be the only option. However, such was not the case. Technology had been developed, proven (by field applications), and patented that caused organochlorides to immediately chemically convert to the non-toxic byproducts of carbon dioxide and chloride ion as they came in contact with the chemical reagent. In situ, while aggressively destroying the chlorinated pesticides, the reactions did not create heat and were not reactive with human skin or tissue. Thus, the safety of the technology was assured and had also been proven under field applications. This technology is referred to as Nucleophilic Substitution Or (SN). Based on the work conducted at the Site, WSP and DeepEarth Technologies, Inc. have demonstrated the effectiveness of the treatment at significantly reducing concentrations of organochlorine pesticides in soils. To date, organochlorine pesticide-impacted soils have been successfully treated in situ to below-site critical PCLs at 79 of 89 treated former residence locations. Four former residence locations were successfully re-treated to below-critical PCLs at a designated Soil Management Area and roughly 6,244 cubic yards of impacted soil excavated from a separate area have been treated to below-critical PCLs. The assessment and treatment activities at the Site have resulted in significant savings compared with excavation and disposal of impacted soils that may be classified as hazardous or Class 1 or 2 non-hazardous waste at an off-site facility. The findings from our current work will lead to a significant increase in efficiency and cost-effectiveness when WSP and DeepEarth Technologies, Inc. begin a similar scope of work for the client at an adjacent site at the beginning of 2024.

Agencies and companies being nominated: Forest Service Pacific Northwest and Southwest staff, USGS Earthquake Early Warning staff, and consultant staff EMPSi, Far Western, and HRAThe US Geological Survey and Forest Service collaborated to site, permit, and construct Earthquake Early Warning (EEW) stations on National Forest System lands. This was the most effective collaboration between federal agencies that the point person for this nomination, Marcia Rickey, has seen in 13 years of NEPA work. What's more, this collaboration was done during a historic pandemic and a historic wildfire season. EMPSi, Far Western, and HRA assisted the USGS and the Forest Service with siting, NEPA and Endangered Species Act compliance, other biological analysis, cultural surveys, and construction monitoring. EEW stations rapidly detect earthquakes and then USGS's cell phone app, ShakeAlert, distributes public alerts that destructive ground shaking may be coming. However, the USGS does not own land, so landowners such as the Forest Service are critical to the USGS's ability to install EEW stations. Before installing an EEW station, the USGS and the Forest Service must comply with environmental laws. Every applicant wants their project to be finished as soon as possible. Realistically, complying with environmental laws may take longer than desired. Recognizing this, we worked together to make a priority list of stations that the USGS wanted to permit first. Prioritizing these stations made the most effective use of the Forest Service and Fish and Wildlife Service staff's time for reviewing documents. We wrote biological assessments for the priority stations first so that the list of stations and species for review was shorter. We wrote safety plans to allow fieldwork during the summer of 2020 (early COVID-19 time, before the vaccine). Safety plans in hand, we expedited field work for cultural surveys and reporting for the priority stations. This priority approach allowed us to permit the first 13 EEW stations in only eight months. The project permitted 182 EEW stations on 14 National Forests in the Pacific Southwest, and 52 EEW stations on 12 National Forests in the Pacific Northwest. USGS is actively constructing EEW stations now. After an EEW station is built and activated, it comes online into the ShakeAlert system. With every EEW station added, the system becomes better at alerting the public.

During an earthquake, seconds matter. The ShakeAlert app, supported by the network of EEW stations we permitted and are constructing, gives the people of California, Oregon, and Washington the seconds they need to prepare. This will improve their safety by allowing them to act accordingly, for example, people can stop what they are doing and take cover. As the use of the app becomes more widespread, safety actions can be taken to cumulatively protect people; for example, preparing for power outages by opening emergency exits, shutting off power in fire-prone areas, or pausing dangerous work until shaking stops. First, we sited EEW stations with a GIS desktop exercise to screen out sensitive locations that were in wilderness, wetlands, or had many sensitive, threatened, or endangered species. Second, we analyzed the impacts to sensitive, threatened, or endangered species in biological assessments and evaluations; we surveyed the EEWs for cultural resources and reported the findings; and we reviewed the EEWs for potential environmental impacts in categorical exclusions. Finally, we used micro-siting (moving the EEW within the analyzed area but outside of an environmental constraint) and field flagging to avoid cultural resources, rare plants, or other environmental constraints.

Have you wondered what is like to be an environmental consultant? Environmental consulting is a career path that incorporates a wide array of multi-disciplinary fields including water quality monitoring, environmental site assessments, protected species surveys, natural resource permitting, impact mitigation planning, and wetland delineations. The field itself is so broad that sometimes one cannot be fully prepared for the learning curve that comes with being an entry-level consultant (i.e. understanding what an environmental consultant does, prioritizing multiple projects at once, managing project expectations, being efficient when budget is limited, etc). Relocating for your career may also present challenges to the adaptation process that students may encounter when starting the environmental consulting journey. There's good news, though! These challenges can be counteracted by preparing yourself with an entry-level career kit. So, strap on your waders and rubber boots and follow me through my personal experience as an entry-level environmental consultant. I will teach you how to easily adapt to an exciting, fast-paced work environment while maintaining a good work-life balance. I will also share strategies to better navigate your first wetland delineation, pre-site visit tips, post-field work best management practices, personal and professional wellness, and more.

The management of construction and demolition (C&D) fines generated from the processing of C&D debris presents significant challenges for recyclers in terms of finding sustainable applications and addressing environmental concerns. This study investigates the potential of hydrogel, a distinctive class of three-dimensional networks formed by cross-linking hydrophilic polymer chains within a water-rich environment, to stabilize C&D fines for construction purposes. The exceptional toughness and mechanical strength of hydrogel have sparked interest in improving the ductility and dynamic loading resistance of construction materials. However, limited studies have explored the use of hydrogel in this context. The primary objective of this study was to evaluate the effectiveness of Ca-alginate hydrogel, an environmentally friendly form of hydrogel, in enhancing the ductility and mechanical behavior of C&D fines. Ca-alginate hydrogel was chosen as the stabilizing agent due to its eco-friendly properties. In this study, The study involved incorporating up to 4% (by weight) of hydrogel into C&D fines to investigate the improvement in their mechanical properties and ductility. The influence of reaction time, sodium alginate content, and curing temperature on the mechanical behaviors of hydrogel-stabilized C&D fines was investigated using unconfined compression tests, falling head permeability tests, and scanning electron microscopy. The results showed that the addition of sodium alginate content significantly increased the unconfined compression strength (UCS) of hydrogel-treated C&D fines, resulting in enhanced load-bearing capacity of the material. The UCS of C&D fines treated with 4% hydrogel achieved an impressive 240 kPa after 7 days of curing.

This session will explore the benefits of reducing vehicle miles traveled (VMT) now and in the future. Many cities across the country and a few states (including California and Minnesota) have statewide policies to support reducing VMT. A major part of the rationale for reducing VMT is to support meeting Greenhouse Gas (GHG) reduction goals. However, reducing VMT overall to date has proven elusive for the economy as a whole and mitigation to reduce VMT for new roadway capacity projects and land use projects is both challenging and costly. At the same time, there is an acceleration of market penetration and an aggressive regulatory push for electric vehicles (EVs) in the light, medium, and heavy-duty vehicle sectors, which will reduce the GHG emission reduction benefits of reducing VMT. This session will present a range of scenarios for VMT reduction, EV adoption, and electrical grid decarbonization to estimate ranges of associated GHG emission reductions. The session will also look beyond GHG emissions to other rationales for reducing VMT including air quality; support of higher occupancy vehicles, transit, and bicycling; and support for land use diversity some of which may change over time due to EV adoption and some of which may not.

During development of a master planning Environmental Assessment (EA) for an Army base in the Gulf Region, the FEMA-mapped floodplains indicated the entire project area would be entirely in the 100-year or 500-year floodplain. However, anecdotal evidence from discussions with Army personnel and a site visit suggested this was not the case. A project to validate the actual flood risk to the installation was initiated and the EA was paused. The purpose of this project was to identify flood hazard threats and communicate the mission impairment risk in a meaningful manner that supports mission adaptation and sustainability into the future. A three-phased planning process was executed to document data collection and analysis, conduct a vulnerability assessment, and develop mitigation actions to address flood risks. The planning process outputs included a) identification of potential flood risks, b) recommended mitigation measures to improve the installation's readiness for future flooding, and c) selection of actionable mitigation measures to communicate sustainability and resilience in response to flood hazard risks. Project-related tasks included FEMA floodplains review, vulnerability assessment of the project area, Floodplain Hazard Mitigation Plan development, and incorporating the flood mitigation into the existing master planning EA. The first step involved reviewing the latest (2016) FEMA Flood Model data, validating the floodplain limits, and confirming whether the buildings/structures were located within a floodplain area. FEMA Flood Insurance Studies (FIS) determine the 100-year and 500-year flood elevations along mapped waterways through hydrologic and hydraulic (H&H) analysis. The flood elevations are transposed onto the topography to develop the Flood Insurance Rate Maps (FIRMS). A topographic review of FEMA-utilized topography against open-source data, as well as reported accounts and field observations, supported the conclusion that the FEMA 2016 FIS overpredicted the flood recurrence intervals and the FIRM was inaccurate. Based on the modeling conducted, Stantec developed a more accurate flood map for conditions and the Army is considering the process of a map revision via the National Flood Insurance Program (NFIP)'s Letter of Map Revision (LOMR) process. A LOMR is a document that allows FEMA to revise flood hazard information on an NFIP map without having to physically revise or reprint the entire map panel. Once accurate data were obtained and mapped, appropriate mitigation measures were developed and identified in the Flood Hazard Mitigation Plan. Lastly, those mitigation measures were incorporated into the master planning EA. The EA explained how the installation was able to address the Eight Step Decision Making Process in Executive Order 11988 for floodplain management through the three-phased planning process. The potential impacts were reduced to less than significant and a Finding of No Significant Impact (FONSI) as well as a Finding of No Practicable Alternative (FONPA) was issued.
