These two methods form the foundation of where the sampling for most of the other stack methods are applied and the determination of the mass emission rate of their target species. The presentation will cover the origin and evolution of the methods and their derivatives and provide in depth treatments of the theoretical and practical aspects of them.  This will include the method applicability and limitations, equipment, and techniques. Information will also be provided on the current state of the art, evolving technologies, and drivers for improving these measurements.

This presentation will provide an overview of the most pressing risk, remediation, and waste management issues associated with PFAS (perfluorinated alkyl substances).  There are thousands of individual PFAS chemicals, although only a handful have been studied or regulated. The webinar will discuss the toxicity and the adverse health effects linked to PFAS, regulatory management strategies, and current approaches for managing and remediating and PFAS-impacted soil and ground water. In addition, approaches used by the US Air Force to evaluate and manage PFAS contamination at their facilities will be discussed.

This webinar addresses current issues associated with transitioning from the old landfill rules to the new landfill rules. The webinar will provide an overview of the substantive rule changes and implementation challenges due to overlapping regulatory requirements. This webinar will provide both a regulatory and legal perspective of the current landfill rules and include:  

•          A brief overview and comparison of existing (NSPS WWW) vs new (NSPS XXX/EG Cf)  requirements.

•          A brief summary of the possible changes to NESHAPs requirements and how these changes  may impact NSPS/EG compliance. 

•          Implementation challenges associated with overlapping requirements and compliance timelines.

•          Challenges to and approaches for modifying Title V permits to include new requirements.

•          Status of final rulemaking. 

On November 20, 2019, the US EPA published revisions to its AP-42 emission factor guide, Chapter 7.1, for estimating air emissions from storage tanks. This webinar will review the final revisions, highlight differences from the proposed revisions, and identify the more significant potential impacts including:

-           Methodology for estimating tank cleaning emissions,

-           Revision of tank temperature equations,

-           Guidance for tanks storing hot stocks,

-           Increase of the default vapor pressure for No. 6 Oil,

-           Addition of emission factors for new deck fitting options, and

-           Statement that EPA's TANKS software “is known to have errors, and is no longer supported.”

This webinar will showcase strategies for agencies to address infrastructure needs to accommodate EV and autonomous vehicles.  This includes a big picture overview of how agencies can successfully work with utilities; a description of how one state evaluated and selected zero emissions vehicle infrastructure projects; design of roadway infrastructure to accommodate electric and autonomous shuttles; and a discussion on truck electrification.

Partnering with Utilities to Implement Electric Vehicle Infrastructure

           Presenter:  Ken Kresyman

In this segment, the speaker will discuss how agencies can work with utilities to implement electric vehicle infrastructure.  It will provide the basics for agencies that are starting electrification and provides tools to partner early with utilities.  This portion will include the basics of power mechanics, how to frame needs with utility companies, and establishing timelines. 

North Carolina – Successful Strategies to Develop Zero Emission Vehicle Infrastructure Projects

Presenter:  Dave Willis

During this segment, the speaker will describe how he helped states develop and select zero emissions vehicle infrastructure project plans.  He will discuss the project scoring process, how AQ reductions were estimated, and describe tools used to review NOX reduction when site usage is not known. Lessons learned on addressing site placement where existing infrastructure was located will be covered.

Development of  Roadway Infrastructure to Accommodate Autonomous and Electric Vehicle Shuttles

Presenters:  Ryan Fetchko and Bruce Doig

Altamonte Springs, Florida, is future focused on improving mobility for its citizens, and autonomous vehicle shuttles are an important part of their plan to be more interconnected. VHB is leading design and construction of a new three-mile multi-modal flexible circulator pathway from an Uptown Altamonte to its Sunrail commuter station. The new path will be a part of a broad network of interconnected multimodal facilities located throughout the city. Participants will learn key design elements of AV paths; traffic, safety, and micro-mobility concerns for incorporating autonomous vehicle Infrastructure and recreational pathways; and best practices for community and municipal stakeholder engagement throughout the process.

A Truckload of Benefits with Electrification

Presenter: Dave Schaller

The trucking industry is now stepping into electrification, but it is a huge change and challenge. Fleets need to understand total cost of ownership and utilities need to understand how time of use impacts those numbers. Both sides are complex, highly regulated and difficult to understand. This segment will discuss how NACFE & RMI are working to bridge the gap between fleets and utilities. The 2021 Run on Less – Electric is an important aspect of establishing benchmarks: real EV trucks with real freight powered electricity for cleaner air.
