11/25/2014 State.co.us Executive Branch Mail - Re: Coal Guidelines Method update suggestions Trapper <br />i Boron (B) ppm Saturated paste extract. Boron: state table 5 referenced off sat paste extraction. Other state <br />lists reference off Hot Water extraction and this is what we perform and it is what is in ASA and other <br />reference materials. Hot water extraction A SA No. 9 method 80 -3. <br />Mercury (Hg) ppm Acid extract Mercury: state table 5 references acid extraction for Hg. Acid digestions <br />volatize Hg and thus Hg is not listed as approved metal on any EPA standard digestion methods such as <br />EPA 3050. Running Hg off a EPA 3050 acid digestion would produce invalid data. ACZ uses a state -of- the -art <br />direction combustion AA for solids for Hg. EPA Method 7473, MILL 2 ng /go <br />* Additional methods may be substituted with prior approval from the Division. <br />* * References which describe these methods: <br />ASTM, 1980, Gaseous fuels; coal and coke; atmospheric analysis: annual book ofASTM <br />Please call me if you have any questions. <br />Kind Regards, <br />Tim J.
