This Air & Waste Management Association specialty conference is the perfect event to provide an important basis for future development and advancements in the air quality modeling field. It will also provide in-person opportunities for stakeholders and regulators to discuss the challenges and techniques to model ever-tightening air quality standards.
The technical program will include an opening plenary session devoted to invited presentations by EPA’s Office Air Quality Planning and Standards (OAQPS) Air Quality Modeling Group (AQMG). Multiple sessions will cover key modeling topics, and the popular Town Hall Meeting will include an interactive Q&A format with high-level regulators and stakeholders.
Determining actual fugitive landfill gas/methane emissions from the landfill surface is hard to quantify. Drone methane and surface emission monitoring conducted on the landfill surface can determine methane concentrations at receptor points around the landfill surface. These receptor concentrations can be used to run an air dispersion model in reverse to solve for the emission rate of the entire landfill surface. This method also allows you to determine a more accurate control efficiency of the gas collection and control system at the landfill based on landfill gas/methane flow to the combustion device. Want to know more?
Jeff Leadford, PE, of SCS Engineers, is presenting “Modeling Fugitive Methane Emissions With Drones” – a not to miss session! Jeff puts his years of experience in the air quality field, with a focus on air dispersion modeling, air permitting and GIS together with advanced drone technology and modeling techniques demonstrating the effectiveness of combining them, especially for landfill owners and operators.
Other session topics include:
Nicole Vogelpohl and Eva Luu attended the “Meet the Regulators” event hosted by A&WMA’s Golden West Chapter at the law firm Holland & Knight in San Francisco. It was an informative event where panelists Dr. Meredith Bauer, Hy Hinojosa, and Lisa Fasano, in for Viet Tran, from the Bay Area Air Quality Management District (BAAQMD), spoke about upcoming priorities, new organizational changes, current organizational issues, and project accomplishments. The three have recently been appointed new deputy executive officer positions at BAAQMD. They are open to taking things in a new direction regarding the permit process, communications with the public, and implementing new and upcoming methodologies for emerging analytical measurement technologies.
Environmental Justice and Air Quality
The panel discussed how, as we’ve learned and made continuous progress in air quality and local emissions reductions over the years, ozone (O3) is now less of a concern (for the Bay Area) compared to PM2.5, which now takes higher precedence as a pollutant of concern. Dr. Bauer and Lisa Fasano mentioned that in the grand scheme of things, we live in a region of great air quality; however, they acknowledge that while the greater San Francisco Bay Area has good air quality as a whole, there are always pockets of localized air pollution that need addressing. Areas specifically pointed out were marginalized communities, such as Bayview/Hunter’s Point and West Oakland. Coincidentally, SCS is currently involved in a project related to the SF Fire Department’s Training Facility moving from Treasure Island to Hunter’s Point. The goal is to ensure the air quality during their training burns will not have long-term downwind effects on the community.
Thorough Discussion Amongst the Panelists and Attendees — Permitting Backlog Issue
The current permitting system needs to be faster, and the backlog of processed permit applications poses challenges for new clients. Attendees expressed frustration and shared testimonies about their clients moving to different states due to the extensive permitting backlog and timely process, which has ultimately halted the emersion of some new regulatory technology and projects in the state. The regulators understand the current system needs reworking and prioritizing to ease and reduce the turnover time of the permit process.
Enlightening and Enjoyable
Hearing the regulators speak passionately about their roles, goals, and investment in the organization was truly pleasing. Thanks to Pat Sullivan for knowing and having worked with everyone we talked to; everyone said hi and spoke highly of you! At “Meet the Regulators,” we connected with stakeholders from local consulting firms, attendees from the petroleum, tech, and waste management industries, and regulators – or, as Dr. Bauer renamed the group, the communicators, to help bridge the gap between the governing board and the general public.

Dr. Ketan Shah’s paper entitled “Single-use plastic bottle emissions using life cycle assessment for the US States, challenges, impact, and recommendations” is publishing in June, but those attending the Air and Waste Management Association conference in Orlando, Florida, have the chance to hear Dr. Shah discuss his methods used to develop methane emission estimates and recommendations to reduce them.
Plastics in solid waste management (SWM) are an exigent and pressing problem for many cities. Globally landfills/open dumpsites are used to dispose of over 80% solid wastes, currently serving around 3.5-4 billion people. This number is expected to grow with increased urbanization and population growth (ISWA, 2015).
Methane generation, recovery, and emissions projections for single-use plastic bottles play a vital role in the recycling industry. The scope of work described in this research project includes providing the basis for the methane estimates that discuss the data, assumptions, and calculation methods used to develop the estimates.
Methane emissions estimates to help assess the potential of single-use plastic bottles will have on greenhouse gas (GHG) emissions. As some U.S. states move towards requiring extended producer responsibility (EPR) for the packaging industry to address its waste management impacts, the analysis for the project commends firms for taking steps to pro-actively find a waste management solution for single-use plastic bottles, which may be the next target for EPR legislation.
Objective 1 – Develop Estimates of emissions from single-use plastic bottles using OpenLCA software based on Life Cycle assessment analysis.
Objective 2 – Prepare Comparative analysis for alternative recyclability scenarios.
Objective 3 – Recommendations and solutions to the single use plastic bottles challenge.
The case study results are based on the assumptions for the emissions from the single-use plastic bottles supply chain from cradle to grave. Finally, recommendations for these impacts and challenges will be discussed in detail. Diverting single-use plastic bottles going to landfills helps in reducing the overall environmental impact.

One of the conference highlights is the Air and Waste Environmental Challenge International (ECi) Competition. ECi gives student teams experience by proposing effective solutions to a simulated environmental problem based on real-world site conditions and events. This year’s competitors were:
The Challenge
Assuming the role as the new Governor of California, the student’s assignment was to choose a sustainable approach to regulate emissions from watercraft and reduce air quality impacts on port communities. Each student team described and justified their chosen program over other options.
This year’s challenge is the Bay Area, where San Francisco and Oakland have large ports with significant populations residing in portside communities. Each team’s research includes existing and proposed studies, policies, laws, and regulations related to emissions from port-related activities and their health impacts on portside communities at the federal and state level, including a critical review of California’s current regulations.
The Judges
The teams presented their solution to a panel of environmental professionals at the Annual Conference this week. Judges included environmental air monitoring experts and those from specialty practices such as technology, sustainability, and regulations. Impressed with the presentations from each school – choosing the ultimate winner was challenging.
All This Suspense – Who Won?
The team from California Polytechnic State University, San Luis Obispo, was selected this year. Cal Poly’s team members include Julia Loew, Ramy Wahba, Anja Cronjaeger, Marcus Lira, and Molly Foster.
Cal Poly’s solution addresses all watercraft with practical elements, including scheduling, speed, education, outreach, and technology. And to create a sustainable solution also addresses economic issues, impacts, and funding sources. The team presented their solution using an infographic (shown below), clearly presenting the path forward year after year.
We congratulate each A&WMA ECi team for their creative and thoughtful presentations. Our communities are in good hands with these soon-to-be professionals.
Dr. Ketan Shah of SCS Engineers will present his paper and findings at the Air and Waste Management Association, 115th ACE-22 conference from June 27-30 in San Francisco, California. Methane generation, recovery, and emissions projections for biodegradable polyester fiber used to create clothing products are growing. This clothing will eventually be disposed of in municipal solid waste (MSW) landfills in the U.S. The scope of work described in this research project includes providing the methane estimates that discuss the data, assumptions, and calculation methods used to develop the estimates.
