Cold Joints in Concrete Walls

Are there any standards or limitations for cold joints in concrete walls (hydrostatic pressure, up to 24 ft tall)?

I can't find anything in ACI that has requirements for this.

(first time posting, forgive me if this has been covered before!)

When you say "ACI" I assume you mean ACI 318 (buildings), which is just a fraction of the 100+ codes, standards, and guides that ACI publishes.
You should consider ACI 350 and 350.4 for water retaining structures.
The term "cold joint" is slightly ambiguous in the industry - it can mean an intentional construction joint (vertical or horizontal edge of a single day pour), or it can mean a horizontal plane where there is poor consolidation - usually as a result of a delay in pumping in the middle of the wall concrete placement (waiting an hour for the next ready mix truck) where the older fresh concrete below began to stiffen when the new concrete above was placed.
I think the term you are referring to is construction joint.
As SRE noted, a PVC waterstop is a minimum. But there are many other design and construction features that differentiate these walls from building walls.
