Quality Assurance/Quality Control (QA/QC) Tom Hare DJ Environmental Cody/Powell WY

QA/QC Includes • Independent onsite monitoring of all environmental aspects of a large 3 D project • Completion of a full monitoring report with permanent photo monitoring plots for future impact analysis • Proof of actual impacts during, immediately after, and one year later • Third party independence

BLM Reasons for QA/QC • BLM has less and less ability to monitor and perform compliance • BLM is unlikely to follow up on long term monitoring • QA/QC monitoring can provide 100% compliance, monitoring documentation, and superior mitigation • No additional cost to the BLM

Industry Benefits of QA/QC • Assurance of 100% compliance to BLM permit requirements • Provides immediate in field access to a BLM representative (QA/QC monitor) w/less delays and immediate resolution of issues • Insurance against shut downs, conflicts and serious problems • Positive BLM views on current and future permits

Overall QA/QC Findings • A series of practical and reasonable BMPs were “discovered” and applied as a result of the on site QA/QC monitor • Work never stopped • Changes and modifications were made in the field with concurrence with BLM manager • Impacts were greatly reduced • Independent documentation of impacts (or non-impacts) was provided

QA/QC Recommendations • QA/QC monitor should be standard practice on large 3 D projects with substantial BLM surface • QA/QC can be applied to any project; not limited to seismic operations • QA/QC can also be used on small, but critical projects (pipelines, well pads, etc. ) • Should not be a default for all projects – just selected projects of special importance • A single onsite monitor is all that is needed in most projects - multiple monitors create conflict and unnecessary costs
