It can go one of two ways - it would depend on size of your DC and percentage of business or flow-thru, also is there anything moving thru the DC that is contracted out - either flow-through no touch, no breakdown etc or are other.
I assume the DC was included in your SQF audit on the facility 10 miles away?
Considering that food storage is a separate certification and not just an add-on it is possible your CB/SQFI will see it was either just an inclusion as a multi-site (without the side certification for the DC).
However, all things considered I'd be asking for a multi-site and it can be included in current cert instead of making another certification.
We had a similar situation about 7 years ago and we almost had to make the food storage facility that was attached to the processing facility a separate certification, but I called into SQFI and they asked for the percentage of the size and volume for the processing as compared to the DC and said that if it were 5!% or more that it would be another certification --- truthfully it was close and it came down to 45% and thus it qualified as being 1 cert under food processing only.
