Second set of questions & answers.

Question 3: During the optional site visit, it was mentioned that once construction starts the area affected by construction would no longer be considered a clean room. Can you confirm that this is still the case and no additional barriers are required to keep the clean room requirement. If this is not the case, can you provide us with areas that are considered a clean room.

Answer 3: B7-a and B7-b, where the new generator electrical feeds and communications are to be installed, should be considered clean rooms for the duration of construction. All other areas where construction takes place are not considered clean rooms.
