I would probably do:

David,

   The table already exists with four attribute columns and their data. I'm
adding four new columns and their data base on the existing row's value in
column site_nbr.

   Based on your and Adrian's responses I'll go ahead and enter the values
filled intert statements for each row.

Why? As David said that will get you an additional 82 rows with data that is dissociated from the existing data. You want to update the existing rows with the new field data for each station.


Thanks,

Rich
