Every four years, America's civil engineers provide a comprehensive assessment of the nation's 18 major infrastructure categories in ASCE's Report Card for America's Infrastructure. Using a simple A to F school report card format, the Report Card examines current infrastructure conditions and needs, assigning grades and making recommendations to raise them. Learning objectives: 1) Overall performance and status of the nation's infrastructure; 2) Leading issues which affect the U.S. infrastructure network and main barriers to addressing these; 3) Solutions to address longstanding infrastructure needs and promote improvements; 4) How the report can help to inform key infrastructure stakeholders including Congress and federal agencies as well as private, and non-profit organizations.

This Energy Exchange recorded session* explores various energy modeling tools, technologies, and best practices.

Per- and polyfluoroalkyl substances (PFAS) are a large and complex class of anthropogenic compounds whose prevalence in the environment are an emerging, worldwide priority in environmental and human health. The ITRC PFAS Team, formed in 2017, has prepared readily accessible materials to present PFAS information to stakeholders, regulators, and policy makers. The PFAS team represents a diverse cross-section of expertise and experience working on PFAS. This training will include emerging science on PFAS, including topics such as Properties of PFAS, Fate and Transport, Sampling and Analysis, and Treatment Technologies. The technical presentations will be focused on those who are relatively new to PFAS.

This course provides the basic information needed to meet the annual refresher requirements in OSHA 29 CFR 1910.120 Hazardous Waste Operations and Emergency Response (HAZWOPER) for workers at hazardous waste sites who have already completed their initial 40-hour or 24-hour HAZWOPER training. Specifically, this course provides the refresher training for workers who perform hazardous waste site operations that are subject to the requirements of 29 CFR 1910.120 (a) through (p).

This webinar will discuss remedial designs and their applicability to projects under the Military Munitions Response Program (MMRP). Topics covered will include the intent of remedial designs and the types of projects for which they are best suited. We will also discuss scoping the remedial design, preparing the MR-QAPP for the remedial design, and finally describe some case study examples.

There will be two presentations, the first titled, "New Monitoring Technologies to Inform CA Least Tern Recovery on DoD Lands". California least terns (CLT), endangered since 1970, have key colonies at Naval Base Coronado and Camp Pendleton, but reproductive success has declined since 2009. This project uses innovative tools--time-lapse cameras, mini radiotelemetry, underwater imagery with computer vision, and fecal DNA analysis--to investigate if limited nearshore fish affect this decline. It aims to improve DoD monitoring efficiency and management of threatened species. If successful, these methods could benefit other endangered species and bolster DoD infrastructure resilience. The second presentation is titled, "Metabarcoding to Assess Habitat Quality for Birds on Military Lands". Monitoring tools for threatened and endangered species (TES) on DoD sites are needed to assess habitat quality and its effects. This project uses DNA metabarcoding to analyze over 1,000 bird fecal samples from five military bases, identifying the arthropods birds eat. This helps pinpoint habitat features that support TES, guiding targeted conservation efforts. These strategies enable DoD to balance mission readiness with effective environmental stewardship.

Beavers are an ecologically and economically important species, providing habitat and clean water as they construct aquatic environments to suit their needs. However, those same behaviors can cause significant damage to timber and infrastructure. In this webinar, you'll learn a variety of situation-specific methods for protecting your property from beaver-related damage.

Join us this quarter for a comprehensive webinar focused on the essential math skills needed to accurately complete facility discharge monitoring reports (DMRs). This session will provide step-by-step guidance on translating lab reports and field measurements into DMR entries. To ensure a solid understanding of these concepts, we will work through a variety of wastewater problems live. Given the complexity of this topic, the webinar will be conducted in two parts.

This memorandum is to provide guidance to Federal agencies as to their implementation of the NEPA. This memorandum includes an overview of NEPA, including a discussion of recent amendments to the statute and recent case law as relevant to agency implementation of NEPA. This memorandum also provides guidance for agencies to use when establishing or revising agency specific NEPA implementing procedures. As part of this guidance, CEQ has provided a template that agencies are encouraged to follow for such NEPA implementing procedures, attached as Appendix 1. This guidance and the associated template are intended to be used by agencies that routinely undertake, or anticipate undertaking, actions subject to NEPA.

Efficient Management of Construction and Demolition (C&D) debris can significantly reduce the vast waste streams generated by demolition waste. This webinar explored how C&D materials, like steel, asphalt, concrete, wood, brick, and drywall, can be diverted from disposal and repurposed into new productive uses, including fuels and manufactured products. Attendees learned practical strategies for source reduction, salvaging, and reusing C&D material to support efficient construction practices and minimize environmental impacts.

Vines are woody or herbaceous plants with relatively long stems. Vines are typically known for their twining or climbing nature. In the US, we have several non-native species of vines that have become problematic and are now considered invasive species. These invasive vines can cause problems such as outcompeting native plant communities, growing into dense thickets, girdling trees, and being extremely difficult to remove. But what are some examples of invasive vines that we find here in the US? What kind of problems do each species cause, and how can they be managed? In this webinar, Chris Evans will discuss the biology, impact, and management of some commonly found invasive vines.
