BNSF
Under BNSF's loading rule, a shipper will be deemed to be in compliance with BNSF's loading requirements if the shipper loads coal cars using BNSF's Load Profile Template and also ensures that an acceptable topper agent is properly applied to the loaded coal at an effective concentration level and in accordance with the manufacturer's specifications. An acceptable topper agent is one that has been shown to reduce coal dust releases by 85%, and three available topper agents have been shown to meet this requirement. A shipper may also seek to include any other method of coal dust suppression (e.g., compaction or other technology) by submitting a compliance plan to BNSF that provides evidence demonstrating that the alternative compliance measure will reduce coal dust releases by at least 85 percent.
