Dear George and Marc, 

For anchoring the RICH assembly structure, we would need to drill about 6 inches into the clean room floor. 

For the drilling process, Walt mentioned this morning we do need a blind penetration permit and also a silica dust hazard analysis. Would there be any other hazard analysis or safety steps we would need for the drilling in the clean room? 

Best regards, 
Tyler
