SERDP and ESTCP Webinar: Improved Approaches for PFAS Sampling and Treatment – January 28, 2021 – 12 noon ET

Join SERDP and ESTCP on Thursday, January 28 for a webinar on DoD-funded research efforts to improve screening and treatment approaches for PFAS. Dr. Graham Peaslee (University of Notre Dame) will discuss the development and field-deployment of a rapid field-screening test for PFAS that greatly reduces the time and costs associated with site characterization and monitoring efforts at PFAS-impacted sites. Then, Dr. Linda Lee (Purdue University) will talk about her research to develop a reductive PFAS transformation technology that employs nickel and zero-valent iron activated carbon nanocomposites.

38th International Conference on Thermal Treatment Technologies & Hazardous Waste Combustors – VIRTUAL CONFERENCE: January 27-28, 2021

Now in its 38th year, this conference provides a forum for the discussion of state-of-the-art technical information, regulations, and public policy on thermal treatment technologies and their relationship to air emissions, greenhouse gases, and climate change. Presentations will address various aspects of waste stream management using thermal treatment processes, and provide useful insight into associated costs, risks, and impacts.

New topics added for 2021 include PFAS sampling, methods, and laboratory analysis, waste/compliance impacts of health pandemics and natural disasters, plastics to energy/closed loop processing, and comprehensive performance testing (CPT).

A&WMA Webinar – Implementing EPA’s New Clean Air Act Policies Under NSR and Title V – Wednesday, December 2, 2020 – 1:00 pm to 3:30 pm ET

Over the last several years, EPA has issued several policy memoranda and rulemakings pertaining to preconstruction permitting requirements under New Source Review (NSR) and operating permit requirements under Title V of the Clean Air Act. Experts in NSR and Title V permitting matters will discuss challenges and implementation issues with regard to the recent policy changes listed below, facing both permitting authorities and the regulated community:

  • Interpretation of “Adjacent” based upon physical proximity between properties
  • Scoping “Ambient Air” based upon a limited change to the application of the “access” element in the regulatory definition of ambient air
  • Interpreting “Begin Actual Construction” proposed guidance, allowing physical on-site activities prior to obtaining an NSR permit, provided that those activities do not constitute physical construction on an emissions unit
  • Plantwide Applicability Limitation (PAL) permitting issues guidance with respect to permit reopening, expiration, termination, and renewal, and monitoring requirements under PAL
  • In the final rule on major MACT to area source (“MM2A”), EPA provides that a major source can be reclassified to area source status at any time upon reducing its potential to emit of hazardous air pollutants below the major source thresholds of 10/25 tpy
