Dear DOE L2s and Deputy L2s,
And while you’re checking the risk registers, please also take a quick 
look at the IIC risk register, version 4.1,
https://atlas-hllhc.docdb.bnl.gov/0001/000196/116/Risk-Register_IIC_v4.1.xlsx  
<https://atlas-hllhc.docdb.bnl.gov/0001/000196/116/Risk-Register_IIC_v4.1.xlsx >,  just 
to make sure that there aren't any items that are obviously out-of-date 
or otherwise incorrect.

Thanks,
Hal and Reinhard
