The space below each of the following questions may be used to record the results ofjudgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage I. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

Only two out of 4 anchors visible (2 are below an insulated box over the pump portion).

2-5/8" anchors identified

2. Is the anchorage free of bent, broken, missing or loose hardware?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

The space below each of the following questions may be used to record the results ofjudgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

Attached to support base with 6-518"diam machine bolts. Support base anchored to concrete with 8-3/4" anchors. Around 10" separation identified with adjacent panels.2. Is the anchorage free of bent, broken, missing or loose hardware?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Drawing RE-0038B confirms anchorage configuration. (see also calc. 52233-CI-01 7).6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
