New US EPA Regulation Change Regarding nPB Use

On June 18, 2020, the US EPA finalized its decision to grant petitions to add 1-bromopropane (1-BP), also known as n-propyl bromide (nPB), to the list of hazardous air pollutants. This change affects facilities that emit 10 tons or more of Hazardous Air Pollutants (collectively) per year.  Any users emitting more than the 10 ton limit will have to file additional paperwork with regulators. Read more about the regulation change here.

For those proactively looking to replace nPB  for their vapor degreasing  cleaning applications, Tergo™ Metal Cleaning Fluid (MCF) makes an excellent nPB alternative.

Here are some of the benefits of Tergo MCF.

  • Exempt from HAP (Hazardous Air Pollutant) calculation: Tergo MCF does not require HAP testing, documentation or reporting.
  • Nonflammable: Tergo MCF is nonflammable, making a preferred choice of OHS (Occupational Health and Safety) officers. 
  • Low environmental impact: With zero ozone depletion potential and a global warming potential under 10, it is a safe, sustainable nPB alternative. 
  • Improved worker safety: Tergo MCF has an ACGIH long-term exposure limit (8-hour TWA) of 200 ppm – 200 times better than nPB. 
  • Proven performer: Tergo MCF has over 5 years  of proven cleaning performance and is NASA approved. 
  • Transition support: The MicroCare Critical Cleaning Lab performs cleaning qualification trials on your parts using Tergo MCF. The MicroCare application specialists also provide ongoing transitioning support to Tergo MCF. 
  • Low conversion cost: In many cases, Tergo MCF uses your existing equipment. After emptying and cleaning the vapor degreaser, Tergo MCF “drops in” to the machinery without an appreciable change to the cleaning process. 
  • Same or better cleaning: Tergo MCF is lab-tested and analyzed, ensuring reliable, consistent cleaning results. 
  • Easier maintenance: Tergo MCF does not require the stabilizers, scavengers or weekly acid acceptance tests like nPB.
