Could someone please confirm the guidance and documentation for projects connected to a third party district chilled water loop? Does the utility (chilled water provider) have to provide any information? These two sources seem to contradict themselves

Guidance from LEED District Energy Addendum
"Scenario 2 – Third Party DES
EAp3 and EAc5 requirements apply to the downstream equipment but not the upstream equipment."

Guidance from 2009 EBOM Reference Guide
"For buildings connected to an existing chilled water system, the chilled water supplier must perform the required calculation and submit a letter showing compliance with the requirements."

Thank you!
