March 2013. Additional details regarding the characteristics of the used oil are provided in the <br /> following table: <br /> Constituent <br /> Characteristic Regulatory or Regulatory Test Results <br /> Citation Parameter Threshold <br /> Ignitability 22 CCR 66261.21 Flashpoint > 140° F >200° F <br /> Corrosivity 22 CCR 66261.22 pH <_ 2 or>_ 12.5 6.82 to 6.85 <br /> Sulfide > 500 mg/kg <0.25 to 2.62 mg/kg <br /> Reactivity 22 CCR 66261.23 Cyanide > 250 mg/kg <0.5 mg/kg <br /> Water Observed None Observed <br /> Reactivity <br /> Arsenic 500 mg/kg <0.20 mg/kg <br /> TTLC <br /> Chromium 2,500 mg/kg <0.20 to 0.527 <br /> TTLC mg/kg <br /> Copper 21500 mg/kg 1.57 to 12.5 mg/kg <br /> TTLC <br /> 22 CCR 66261.24 Lead 1,000 mg/kg <0.20 to 1.25 mg/kg <br /> g <br /> Toxicity TTLC <br /> Molybdenum 3,500 mg/kg <2.0 to 9.65 mg/kg <br /> TTLC <br /> Zinc 3,500 mg/kg 4.59 to 13.1 mg/kg <br /> TTLC <br /> PCBs 50 mg/kg <2.0 mg/kg <br /> (TTLC) <br /> 96-Hour LC50 <500 mg/I > 750 mg/I <br /> Rebuttable 22 CCR 66279.10 Total < 1,000 mg/kg <0.0005 mg/kg <br /> Presumption Halogens <br /> Flashpoint >_ 100° F >200 ° F <br /> Lead <50 mg/kg <0.20 to 1.25 mg/kg <br /> Arsenic <5 mg/kg <0.20 mg/kg <br /> Standards of HSC 25250.1(a)(3)(b) Chromium < 10 mg/kg <0.20 to 0.527 <br /> Purity mg/kg <br /> Cadmium < 2 mg/kg <0.20 mg/kg <br /> Halogens < 3,000 mg/kg <0.0005 mg/kg <br /> PCBs < 2.0 mg/kg < 2.0 mg/kg <br /> The results of these analyses indicate that used oil generated from a typical BNSF facility does <br /> not exhibit any of the characteristics of a hazardous waste, meets the rebuttable presumption <br /> requirement for total halogens, and meets the standards of purity as defined in H&SC 25250. A <br /> copy of the laboratory analytical report of used oil samples obtained from the BNSF Barstow <br /> facility is provided in Appendix A. <br /> 1.5 Factors Unique to BNSF Used Oil <br /> Unlike other facilities that generate used oil, BNSF controls the maintenance and repair of <br /> locomotives, rail-bound and off-road equipment throughout the life of the asset. No halogenated <br /> solvents are used in the maintenance of BNSF locomotives or other rail-bound and off-road <br /> equipment. This control ensures that no deleterious additives, including those that could impact <br /> Hazardous Waste Variance Application 4 July 29, 2014 <br /> BNSF Railway <br /> TRC Project No. 211983 <br />
