Attachment 3 Follow-on IVS QC Checklist This checklist is to be completed by the Field or Project Geophysicist every time IVS data is collected (at least twice per day at the beginning and end of each day’s data collection). Performance of the IVS and completion of this checklist will also be observed by the QC Geophysicist and documented in the Geophysics Daily QC Report. QC Step QC Process Initial of Field or Project Geophysicist Qualifications Are the same geophysical personnel being used as in SOP 1? If not, have the qualifications of the new personnel been verified? Preparation Have the start-up procedures and pre-operation checklist from SOP 1 (Attachment 1) been successfully completed? Data collection Is the IVS data collected i/a/w this SOP? Data processing Did the Data Processor process the IVS data i/a/w this SOP? Data analysis Is the data collected on the blank space suitable for use as background i/a/w this SOP? Data analysis Are all decay amplitudes within 10% of the mean of those previously measured at each location i/a/w this SOP? Data analysis Was the background data from the blank space used to correct the target data sets and to invert the data i/a/w this SOP? Data analysis Do the resulting polarizibilities match the expected library values with a match statistic of 0.9 or greater i/a/w this SOP? MQO Documentation Have the appropriate MQOs from Worksheet #22 been achieved?

final grids of Z-component amplitude response for delivered area subset final grids of detection metric (if not amplitude response) for delivered area subset processing/data selection letter report SOP 5T Attachment 1 Dynamic TEMTADS Data Processing QC Checklist This checklist is to be completed by the data processor or Project Geophysicist for every delivered data set (usually a contiguous subset of the project survey area). QC Step QC Process Yes/No Initial of Field or Project Geophysicist Function Tests Was the functionality of the TEMTADS EMI components verified for each sortie using function tests and did all function tests pass the MQO for this test? IVS Tests Was the functionality of the TEMTADS system verified for each sortie using IVS tests and did all IVS tests pass the associated MQOs? Data Validity Were invalid data for each sortie (with regard to Tx current, GPS fit quality, IMU data quality, and EMI response within range) identified and rejected? Coverage Were gaps in data coverage due to down-line and across line sampling identified and accounted for (obstructions)? Background removal Was the background model inspected prior to subtraction from the raw data and was the leveling reviewed by the QC Geophysicist? Target selection Was the final target list reviewed by the data processor and the QC geophysicist? Reporting/deliverables Were the following documents completed and delivered: Digital Field notes Data processing log Target List Final data archive (gdb or xyz format) Final grids
decay data met? Cued measurements Do the derived models for each classified anomaly fit the observed data with a fit coherence that meets the MQO with exceptions added to the dig list as can’t analyze (dig)? Cued Measurements Do all targets classified as non-TOI have a fit position offset from the center of the array that meets the MQO? Reporting Does the classification report describe the classification approach and identify the decision thresholds used to place an item on the non-TOI list?

observed by the Project geophysicist who will document the implementation of this SOP in the Geophysics Daily QC Report. The measurement quality objectives (MQOs) are presented in Worksheet #22 of the QAPP. Reporting Achievement of the Recovered Object Verification MQOs (see QAPP Worksheet # 22) will be documented by the QC Geophysicist by completion of the QC Checklist in Attachment 1 to this SOP. SOP 9 Attachment 1 Follow-on QC Checklist for Recovered Item Verification This checklist is to be completed by the QC Geophysicist for a series of recovered items. Series of anomalies covered by this verification: From __________ To ___________ Date:__________ Time:__________ QC Step QC Process Yes/No Initial of Data Processor Qualifications Is the same QC Geophysicist being used? If not, has the qualifications of the new personnel been verified? Recovered object comparison Did the QC Geophysicist compare each recovered item to the analysis predictions i/a/w this SOP? Resolution of mismatches Was each mismatch successfully resolved (Section 3.2) and the resolution documented in a verification report i/a/w this SOP? MQO Documentation Have the appropriate MQOs from Worksheet #22 been achieved?
