"On July 11, 2018, as part of pre-planned maintenance, the site meteorological tower will be removed from service.

The tower will be out of service for approximately 11 days.

As a result, this is reportable under 10CFR 50.72 (b)(3)(xiii).

During the time the data is not available from the meteorological tower;
compensatory measures will be in place to obtain the data from the National Weather Service if necessary.

"The [NRC] Resident Inspector has been notified."

[ Site weather info helps them determine when and how much goo they can spew. ]  

I was wondering what weather criteria they might use to help them determine when and how much goo they can spew?  Do you have any further info or observational data?  I have noticed visible emission releases happening  at Fukushima when it rains.  I've wondered if this was to hide emissions from public view or to help limit how far the emissions might spread.   I would guess that wind direction would also be an important consideration to limit the fallout over more populated regions.  

Many thanks for the work you post here, your comments are helpful to understanding the operational reports the industry is required to file.
