On page 51507, in Appendix A-8 to Part 60, in Method 30A, in section 9.0, in the fourth column of the table, in the tenth line from the bottom of the column, ``percentages..'' should read ``percentages.''. 2. On the same page, in the same appendix, in the same section, in the fifth column of the table, in the third line from the bottom of the column, ``initial dynamic'' should read ``initial run; dynamic''. 3. On page 51508, in the same appendix, in the same section, in the table, entry ``A'' is corrected to read as follows: Summary Table of QA/QC Requirements--Continued ---------------------------------------------------------------------------------------------------------------- Acceptance Status\1\ Process or element QA/QC specification criteria Checking frequency ---------------------------------------------------------------------------------------------------------------- * * * * * * * A.............................. Sample Point Stratification Test (See If the Hg Prior to first Selection Section 8.1.3). concentratio run. n\2\ at each Prior to 1/1/09, traverse you may (1) forgo point during stratification the testing and use 3 stratificati sampling points on test is: (as per Section 8.1.3.2.2) or (2) Within < plus- perform a SO2 minus>5% of stratification mean, use 1- test (see point Sections 6.5.6.1 sampling (at and 6.5.6.3 of the point appendix A to closest to part 75), in lieu the mean); of a Hg or stratification Not test. If the test within < plus- location is minus>5% of unstratified or mean, but is minimally within < plus- stratified for minus>10% of SO2, it can be mean, use 3- considered point unstratified or sampling. minimally Locate stratified for Hg points also. according to Section 8.1.3.2.2 of this method. Alternatively , if the Hg concentratio n at each point is: Within < plus- minus>0.2 [mu]g/m\3\ of mean, use 1-point sampling (at the point closest to the mean); or Not within < plus- minus>0.2 [mu]g/m\3\ of mean, but is within < plus- minus>0.5 [mu]g/m\3\ of mean, use 3-point sampling. Locate points according to Section 8.1.3.2.2 of this method. * * * * * * * ---------------------------------------------------------------------------------------------------------------- 4. On page 51509, in the same appendix, in section 12.1, in the first column, in the 13th line from the bottom of the column, ``Cbaseline'' should read ``Cbaseline''. 5.

On the same page, in the same appendix, in the same section, in the same column, in the 17th and 18th lines, ``R= Mean value of spike recoveries at a particular target level, %;.'' should read ``R = Mean value of spike recoveries at a particular target level, %.''. 7. On the same page, in the same appendix, in the same section, in the same column, in the 19th line, ``%;.'' should read ``%.''. 8. On page 51522, in the same appendix, in Method 30B, in section [[Page 55279]] 9.0, in the table, in the second column, in the last two lines of the column, ``<10% of section 1 Hg mass for Hg concentrations > 1 [mu]g/ dscm;.'' should read ``< =10% of section 1 Hg mass for Hg concentrations > 1 [mu]g/dscm;''. Appendix B to Part 60 [Corrected] 9. On page 51527, in Appendix B to Part 60, in the second column, in section 8.6.6.1, in the third line ``Eq. 12A-1'' should read ``(Eq. 12A-1)''. Appendix K to Part 75 [Corrected] 10. On page 51530, in Appendix K to Part 75, in section 8.0, in the table, in the third column, in the 13th line, ``analyzing field.'' should read ``analyzing field samples.''. 11. On the same page, in the same appendix, in the same section, in the same table, in the fourth column, in the third line, ``Sample check invalidated'' should read ``Sample invalidated''. 12. On the same page, in the same appendix, in the same section, in the same table, in the same column, in the 12th and 13th lines, ``analysis samples until successful'' should read ``analysis until successful''.
