The guidelines below apply to all waste fuel materials.
Materials that exceed these criteria may be accepted on a case-by-case basis and with prior notification if they can be blended to meet the guidelines, except as noted.
750ppm 40ppm 440ppm 7,500ppm 2,900ppm 10*ppm 25,000ppm 90,000 ppm
*Until an upper limit for mercury is established, GRR asks that all waste shipments contain < 10 ppm mercury. This is because the total mercury that GRR receives in waste shipments varies daily which can affect the acceptance of a load.
