It's been a while since I've read through the Uniform Plumbing Code and I recall, in an earlier edition, that plumbing needed to be routed from an elevator pit sump pump to an indirect waste connection via an air gap to prevent backflow. However, in the 2018 edition, I no longer see any instructions outlined. Previously it was in section 710, has it been moved?

Does the Uniform Plumbing Code no longer detail how to route plumbing from an elevator pit via a sump pump?
I don't see anything specifically about elevators, but there is Chapter 8, indirect wastes which includes:
805.0 Pressure Drainage Connections.
805.1 General. Indirect waste connections shall be provided for drains, overflows, or relief vents from the water supply system, and no piping or equipment carrying wastes or producing wastes or other discharges under pressure shall be directly connected to a part of the drainage system.
The preceding shall not apply to an approved sump pump or to an approved pressure-wasting plumbing fixture or device where the Authority Having Jurisdiction has been satisfied that the drainage system is adequately sized to accommodate the anticipated discharge thereof.

301.6
Plumbing systems shall not be located in an elevator shaft or in an elevator equipment room.Exception:Floor drains, sumps and sump pumps shall be permitted at the base of the shaft, provided that they are indirectly connected to the plumbing system and comply with Section 1003.4.
This is in the IPC, International Plumbing Code. The OP was asking for a Uniform Plumbing Code reference, and I don't see one. Maybe the OP was thinking IPC though, that might explain it.
OP's location says Kansas, and according to this map, they use the UPC.
This map is kind of funny, the first page makes it look like IPC is predominant, and the second page looks like it's mostly UPC...

I do not know about Kansas, but,
In CA:
The California Code of Regulations, Title 8, Elevator Safety Orders requires that a sump and sump pump (not connected directly to the sewer) or a drain (not connected directly to the sewer) be installed in pits of elevators installed under Group III regulations in order to prevent the accumulation of water.
( they do not want the Hydraulic fluid and oil in the sewers)
All elevator pits for elevators that have Firefighters' Emergency Operation shall have a drain or sump pump in accordance with ASME A17.1 Section 2.2.2.5.
