Landfill gas system rules are changing – SWANAPALOOZA resources help navigate the maze!

June 16, 2020

SWANAPALOOZA and SCS Engineers professionals and resources help manage operational, environmental, and budgeting needs.

On March 26, the U.S. Environmental Protection Agency (USEPA) finalized amendments to the 2003 National Emission Standards for Hazardous Air Pollutants (NESHAP) for Municipal Solid Waste Landfills. The NESHAP rules affect air permits and landfill gas system operating requirements for most active landfills.  Read the Technical Bulletin here.

Some permittees welcome the revised wellhead operational standards, but other changes including additional monitoring requirements for wells operating at higher temperatures, and correction and clarification of Startup, Shutdown, and Malfunction (SSM) requirements are creating confusion. Landfill owners have an 18-month phase-in period before full compliance with the NESHAP requirements, so now is the time to unravel the confusing language between NESHAP rules and existing New Source Performance Standards (NSPS) rules (Subpart WWW and Subpart XXX).

SCS Engineers and SWANA are presenting a series of webinars and resources to help landfill owners and operators untangle the confusing permit phraseologies and implications created when state agencies with air permitting authority incorporate the NESHAP requirements into Title V operating permit renewals and construction permits.

Tune in for advice on Wednesday, June 24, 3:40 PM – 4:15 PM:

SWANAPalooza 2020 Virtual Conference —  Navigating the Maze of Federal Air Quality Regulations for Landfills with Pat Sullivan. Pat and other presenters will discuss the EPA’s landfill regulations, including NSPS, NESHAP, and Emission Guidelines.

Tune in earlier for other key presentations including:

  • Treatment advice targeting emerging contaminants,
  • Solid waste planning for an uncertain future,
  • Using remote monitoring and control to automate regulatory LFG, liquids, and SSM reporting among others,
  • Free on-demand presentations for technical, budgetary, and financial needs; private chats; resource materials; and even entertainment at the SCS Engineers virtual booth.


We look forward to seeing you at SWANAPalooza 2020!

PFAS false-positive detections can lead to unnecessary expense and investigations

January 22, 2020

When a release of PFAS occurs at a metal finishing facility, it is often due to the integrity of the wastewater system. Due to the persistence of PFAS and very low concentrations considered to be toxic, even water containing a small amount of PFAS can result in a large impact on the environment. If water can migrate into the subsurface, so can PFAS. Once in the soil, any water introduced into the soil can transport the PFAS into the groundwater.

The Californian chrome plating facilities are being required to test for PFAS even if there is no evidence of historical contamination at the property from any chemicals. Current testing is requiring the analysis of 25 different kinds of PFAS, including PFOS and 6:2 FTS.

Because such low concentrations of PFAS are considered to be toxic and their prevalence in common consumer products and tools, false-positive detections are common during the investigations for PFAS. False positives detections can lead to unnecessary expense and additional investigations. Therefore, selecting a knowledgeable, skilled, and experienced environmental consulting firm, is paramount to keeping the investigation as low cost as possible.
