The findings of the studies reviewed in this report are encouraging concerning the ability of today’s U.S. WTE facilities to effectively treat solid waste that contains PFAS and not emit detectable levels of PFOA in the process. For the formation of PICs, the pilot-scale investigation conducted at the Karlsruhe Institute of Technology is encouraging in its findings that the combustion of PTFE did not create any of the 31 types of PFAS suspected of being potential PICs produced during the combustion process.
In conclusion, based on this research, SWANA is cautiously optimistic regarding the role of WTE facilities in the destruction of PFAS in MSW. The thermal destruction of PFAS in high-temperature combustion systems such as WTE facilities may represent one of the few commercially proven options available to society to destroy these problematic, forever chemicals.
The full report, PFAS Fate and Transport in Waste-to-Energy Facilities, is currently only available to SWANA ARF subscribers. SWANA members receive free access to ARF industry reports one year after publication; the abstract is available online and worth reading.
SCS periodically prepares Technical Bulletins to highlight items of interest to our clients and friends. We publish these on our website.
Our most recent Bulletin summarizes and updates the TCEQ’S New Rules Implementing Compliance and Registration Requirements for Coal Combustion Residuals (CCR) Management. In addition, this Bulletin covers TCEQ’s development of a program for implementing the Federal rules governing CCR facilities in Texas. While TCEQ’s CCR program needs to be at least as protective as the federal CCR rules, there are important distinctions in Chapter 352.
SCS’ Texas-based professionals are experts on TCEQ’s new program for registering coal combustion residue (CCR) sites. We are currently working to support multiple sites needing to meet the December application deadline. Our engineers and geologists know how to use site-specific design and related technical documents to complete TCEQ’s detailed application for a registration consistent with TCEQ’s new regulatory program.

Staff, family, and friends of SCS Engineers Miami and Boca Raton offices braved the intermittent scorching heat and torrential downpours to reign supreme at the 8th Annual Kick CF Celebrity Kickball Tournament in Palmetto Bay, Florida. After three previous showings that fell short, SCS Ballbarians Team Captain Troy Schick shared that “the timing of the win was a perfect way to safely reconnect as an office after 14 months of remote working. We were able to focus on having fun, which was our key to success!”
Highlights included a strong defensive performance by Marc “The Pride of Buffalo” Lefebvre and dazzling base running by Troy Schick who made the highlight reel by stealing second base on UM gridiron standout and 14-year NFL veteran wide receiver Santana Moss.
Emily Vasquez organized the event with support from Claudia Pineda and Natasha Wylie. The team and cheering section included Aidan Gallagher, Dustin Philipp, Evan Darpini, Tim Tedesco, Marc Lefebvre, Daniel Dietch, Daniella Dobrowolski, Anabel Rodriguez-Garcia, Thiago Vega, Emily Vasquez, Claudia Pineda, Natasha Wylie, Rebecca Wylie, and our ringers, Miguel Ponce, Elan Bustamante, Alex Saavedra, Eric Saavedra, and Rick Sanders and Judah Dietch.
SCS Engineers was proud to sponsor the event to benefit the Cure Cystic Fibrosis Miami, a local family foundation, to raise awareness and funds for the Cystic Fibrosis Foundation to fulfill its mission to cure cystic fibrosis and to provide all people with the disease the opportunity to lead full, productive lives by funding research and drug development, promoting individualized treatment, and ensuring access to high quality, specialized care.
California’s AB 32 legislation has proven to be one of the most successful legislation in the U.S. regarding statewide efforts to reduce GHG emissions. This has been started with the implementation of the early action measures stated in the Scoping Plan, which included early regulations to reduce GHG emissions in many different industry sectors, and then moved to the establishment of the MRP and C&T programs, which have created incentives for facilities to reduce their GHG emissions. The nine early action measures have been documented to reduce California’s GHG emissions with an estimated reduction of 13.16 percent from 1990 emissions in the year 201813. As a result of these programs’ implementations, California has met its goal to reach 1990 emissions levels by 2020 and had done so by 2016, four years before its proposed target year.
With the continued implementation of new programs at the state, local, and federal level, growing economic incentives to reduce emissions, and drive that led to the success of the emissions reduction goals of AB32, California is on a very promising path to achieving its latest goals to combat climate change.

The purpose of SCS’s internal Quality Management System (QMS) is to provide our clients quality solutions ethically. With that goal in mind, SCS Tracer Environmental (a specialty practice at SCS Engineers) has developed numerous internal systems to provide quality consulting services.
For example:
To help our clients stay in compliance, Tracer developed another quality-related system to track recurring compliance due dates for our nearly 400 clients. Our due date tracking system allows us to generate reminders for them before their actual need.
Tracer’s system of quality programs has evolved; however, the key component of providing quality solutions remains unchanged – teamwork. Without teamwork, no quality system will create success. This collaborative effort within Tracer and other practices at SCS Engineers helps us achieve our common goal of delivering quality solutions.
Sometimes that means we need to step up and help a colleague on a project with a quick turnaround time. Or, if the unexpected happens, a new project manager may need to jump in – sometimes mid-project. We take the initiative to respond to all client emails if we know the client manager is unavailable. We form internal committees to revise procedures, checklists, and templates, always intending to improve efficiency and increase quality.
Merriam-Webster defines teamwork as “Work done by several associates with each doing a part but all subordinating personal prominence to the efficiency of the whole.” With mutual trust and respect, and the free exchange of knowledge in a collaborative environment, we continue to deliver quality through teamwork.
We thank our SCS Quality Management Gurus, who are always helping us find better ways to deliver excellence!

The main thoroughfare in Madison, Wisconsin, leading to the state capitol, is going through a major renaissance. Once an idle brownfield, and before that an active industrial-commercial area, the entire block has now been converted to residential, commercial, and office spaces, as well as a youth art center. After extensive due diligence to assess, then successfully remediate significant adverse environmental conditions from past uses, the property’s new mixed-use buildings are open for occupancy. The community art center opens in 2021.
The block formerly housed a dairy operation, gas station, auto maintenance shops, a print shop, and a dry cleaner. These past uses and the historic fill placed on the property resulted in chlorinated solvents, petroleum, polycyclic aromatic hydrocarbons (PAHs), and heavy metal contamination.
Remediating and mitigating environmental contamination and redeveloping brownfields like this one into vibrant, revenue-generating community assets takes pooled expertise from multiple disciplines, including hydrogeology and environmental engineering.
While these projects can provide high value for communities long into the future, they are complex and require large investments up front, explains Ray Tierney, an SCS vice president. Having a team that gets a full picture of the property’s environmental condition, knows regulators’ expectations, and can identify technically sound, cost-effective remediation and mitigation approaches can translate to substantial money savings.
In this case, a solid knowledge base and vetting key details resulted in seven-digit figure savings and facilitated prized redevelopments.
“We identified the amount of soil and groundwater contamination, evaluated strategies to best address the issues, and came up with a cost estimate for remediation. Based on the estimate, along with documentation validating the scientific rationale for our recommendations, the seller reduced their price to account for the legacy environmental liabilities which the purchaser agreed to accept and address as part of the property’s redevelopment.”
SCS Engineers assessed for contamination; oversaw the management of contaminated soil and groundwater during construction according to the materials management plan; supported the client in securing grants, permits and documented compliance with the approved planning documents.
For this project, as is often true in historic urban areas, the greatest expense was dealing with widespread contamination found in the historic fill soils and with groundwater issues.
“Our client is obligated to handle contaminated materials properly. We plan and permit the proper procedures, work with contractors to facilitate the work, documenting that procedures and plans are followed while making sure they only invest what is necessary to be judicious in protecting the environment and public health,” says the SCS Project Manager and Geologist Dr. Betty Socha.
During construction, Socha’s team was onsite to assist contractors in complying with environmental plans and permits, documenting that activities were completed safely and in compliance with Wisconsin Department of Natural Resources (WDNR) expectations. The team oversaw soil removal and management during site demolition and construction of the foundation, including piles and a structural slab. This support system reduces the geotechnical requirement of the underlying soils to reuse more onsite soil safely. But knowing what soil is acceptable and orchestrating the separation of contaminated and non-contaminated materials takes specialized expertise and skill.
“During construction, we evaluate soil conditions, so contaminated soil is safely disposed of at a landfill. But landfilling large volumes of soil is a considerable expense, so it’s important to determine what is safe to be segregated as clean soils for reuse elsewhere. Knowing how to do this efficiently will minimize disposal costs and maximize the use of valued resources,” Socha says.
Getting a handle on groundwater conditions and identifying the best management strategy requires equal attention.
“This property sits on a strip of land (an Isthmus) between two large and prized lakes, with a shallow water table. We thoroughly assessed the groundwater (aka, hydrogeologic) site conditions and managed groundwater generated during construction and dewatering activities,” says Tierney.
“We documented the extent of contamination, and the WDNR confirmed our evaluation that no additional remedial groundwater treatment systems were needed. We could show the contamination was contained enough to pose no risk to municipal wells, private wells, surface water, or other sensitive environments. However, the client still needed a permit to dispose of the contaminated groundwater generated during dewatering for construction of the building foundation and underground utilities,” says Tierney.
Major brownfield redevelopment projects are involved with multistep processes. They begin with a Phase I Environmental Assessment entailing an inspection of the property and a historical review.
That’s where SCS initially identifies potential or existing environmental liabilities from contamination. Then the team confirms the presence of multiple soil and groundwater contaminants through a Phase II Assessment, involving collecting and analyzing soil and groundwater samples.
Next comes a site investigation, a robust testing program to see exactly what is going on. This is where the team further defines contamination, locations, how far it spread, and concentrations. That information lays the groundwork for developing the remedial action plan to file with the WDNR. The team then works with the redevelopment contractors to seamlessly and concurrently manage both the property’s remediation and the buildings’ construction.
In Madison, Socha, Tierney, and their team also helped the developer apply for and win a $500,000 brownfield grant from the Wisconsin Economic Development Corporation, a practice that is as much an art as a science. Additional public support for the project was also received through tax incremental financing (TIF) and the Wisconsin Housing and Economic Development Authority (WHEDA) tax credits for low‐income housing.
“We merge our technical backgrounds to show the land has the potential to be turned into a strong asset that addresses the legacy environmental contamination, promotes public health, and delivers a high-value property that pays taxes and supports important city services,” says Tierney.
It takes technical horsepower to show regulators just how you are addressing contamination. You need to show the economic development group awarding the grant that the project will create well-paid jobs and tax revenue. Equally important, it must be shown that the redevelopment helps address a community need for affordable workforce housing and additional market-based housing,” Tierney says.
Tenants have already moved into the two 11-story mixed-use buildings. In addition, The Madison Youth Arts Center (MYAC) is slated to open in early summer, with a grand opening ceremony this fall. The MYAC includes classrooms, offices, rehearsal spaces, and a 300-seat auditorium.
The final project showcases the heartbeat of this popular downtown space situated between two large lakes, with features such as a rooftop terrace, plazas with seating and green space, and soon to come are 3D urban art installations and murals that tell the story of this long-lived community.
“The redevelopment of brownfields and the creation of projects like the Lyric and the Arden align with the City of Madison’s Performance Excellence Framework Vision of Our Madison – Inclusive, Innovate, and Thriving. These types of redevelopment projects help the City act as a responsible steward of our natural, economic, and fiscal resources. While making efficient use of land and cleaning up brownfields, the City is able to provide workforce housing, job opportunities, and cultural venues, all while enhancing the City’s tax base,” says Dan Rolfs, the Community Development Project Manager for the City of Madison’s Office of Real Estate Services – Economic Development Division.
It takes a village, or in this case – a City, to revitalize an urban brownfield!

A Nebraska city earned an $800,000 grant from the Environmental Protection Agency. The City of Lincoln plans to use the grant to assess and clean up brownfield sites, including up to 10 acres of land city officials hope to use for self-sustaining urban agriculture projects.
Officials plan to create a self-sustaining urban agricultural area in two adjacent 5-acre parcels for lease by local farmers. Lincoln can begin moving local food production into commercial use by local businesses.
In a recent Journal Star article, Tim Rinne, chairman of the Lincoln-Lancaster County Food Policy Council, said, “Rather than continuing to rely exclusively on drought-stricken and wildfire-plagued California to produce the bulk of our produce, or waiting for the next breakdown of our national food distribution network like we saw with the COVID-19 crisis, Lincoln’s city government leadership is taking the visionary and cautionary step of building a resilient local food system.”
The planned agricultural use also helps protect surrounding developments. The five-year grant will help the city assess four other sites in the area and could support cleanup plans at two more sites.
