Mark Johnson to Moderate and Jeff Tyburski to Present on PFAS and Brownfields at the Tri-State Environmental Law Conference

Mark Johnson will moderate a session, and Jeffrey Tyburski, P.G. (North Carolina) will present at the South Carolina/North Carolina/Georgia (SC/NC/GA) Tri-State Environmental Law Conference at the Francis Marion Hotel in Charleston, South Carolina on June 17 - 19, 2022.

Mark will moderate a session entitled "PFAS-Forecasting a Changing Regulatory Landscape," and Jeff will present "Emerging Regulatory Trends – Brownfields Development" in the Hot Topics session. Several Geosyntec staff members will be at Booth #4 to meet with conference attendees.  

Mark Johnson is a Principal Consultant based in Maryland with more than 23 years of experience focused on transactional support, site investigation and remediation, subsurface vapor intrusion to indoor air, environmental management assessment and systems, and brownfield redevelopment planning and design.

Jeffrey Tyburski is a Principal Geologist based in North Carolina with more than 32 years of experience focused on environmental brownfields redevelopment solutions to support property due diligence and acquisition, site redevelopment design, site construction, and post-occupancy property management.

The Tri-State Environmental Law Conference attendees will cover the similarities and differences of key environmental issues between North Carolina, South Carolina, and Georgia. Their environmental landscape continues to change as understanding of emerging contaminants, climate change, energy and water, and natural resources continue to evolve from legal, regulatory, technical, and political perspectives. This program will provide new and exciting updates from regulators, legal experts, and stakeholders about topics at the forefront of the field.

The South Carolina Bar was established by the Supreme Court of South Carolina (SC Appellate Court Rule 410). Its mission is to uphold the integrity and honor of the legal profession, advance the science of jurisprudence, promote high quality legal education and services to the public and continually improve the administration of justice throughout the Palmetto State.

Geosyntec Participation

Title: PFAS-Forecasting a Changing Regulatory Landscape
Moderator: Mark A. Johnson, Geosyntec Consultants, of NC, P.C.
Speakers: Kim Nimmer, NCDEQ, Jean Zhuang, Southern Environmental Law Center, Jeaneanne Gettle, EPA Region 4 Director of the Water
Time/date: 9:30 – 10:30 a.m. EDT, Friday, June 18, 2022
Abstract: Contaminants of emerging concern, such as per- and polyfluoroalkyl substances, or PFAS, include many thousands of chemicals that are used in our products and released into our air, water, and soil. These chemicals may be considered "emerging" because they may pose newly identified (or newly publicized) risks to human health or the environment. At the federal level, the U.S. EPA recently released a document titled PFAS Strategic Roadmap outlining an agenda to address PFAS. At the state level, some states are adopting, or have adopted, drinking standards; others are addressing the chemicals through consumer product legislation or Clean Water Act permitting. This panel will present several perspectives on this complex topic focusing on PFAS, and will discuss the various roles of governmental agencies, industry, and public stakeholders as we work collectively to address this complicated issue.

Title: Emerging Regulatory Trends – Brownfields Development
Speaker: Jeff Tyburski, Geosyntec Consultants of NC, P.C.
Time/Date: 10:45 – 11:30 a.m. EDT, Saturday, June 18, 2022
Abstract: Many "easy" brownfields sites have been purchased and developed leaving more challenging sites behind. Increasing land values and economic incentives have made the development of challenging sites more viable. Development is trending towards more heavily contaminated sites, including pre-regulatory landfills. A number of technical challenges have presented themselves as a result of this development trend, such as managing methane and other landfill gasses and the need for more robust engineering and institutional controls to be protective of future occupants. The trend has also resulted in regulatory guidance's and policy updates which can provide economically viable solutions to manage and/or safely reuse urban soils and reduce pressures on available space for State Permitted landfills.
