Yeah, whatever chapter says "powerplant" on it...I am sure you're big enough to find it. I've flown the ATR all variants for more than 8 years, and on 4 continents, but not recently, so my memory of TOC numbering may not be up to date.
ATR made a point not to follow ATA chaptering for the FCOMs, not to mention the "great" books they pull out for Normal ops...even more confusing!
