4 This parameter is the EQS expressed as a maximum allowable concentration (MAC‑EQS). Where the MAC‑EQS are marked as "not applicable", the AA‑EQS values are considered protective against short‑term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity.
RO interpretation:
When MAC‑EQS is marked as "not applicable“  MAC‑EQS = AA‑EQS

with the new requirements related to MAC we will have difficulties in implementation at the national level
may be MAC‑EQS = AA‑EQS is not applicable everywhere ?!!!?
if so, this should be done on case by case basis  more clear guidance is needed
other views/opinions???
