Rich,
Don't like to see them outside the room with water heater, but you really can't get anyone to change the stupid rule. Recently, had the fact that one similar to yours was in accordance with manufacturer's rec. and the county and the state code. Now what I do is include reasons (As quoted from IRC) and mark it IMO. Sorry, condemnation still ringing in my ears.

I think it should go into the kitty-litter box!

The following recommendations regarding TPR discharge pipes are based largely on the 2006 International Residential Code P2803.61 as well as other building and plumbing codes.
The discharge piping serving a TPR valve should:

Be constructed of an approved material such as CPVC, copper, polyethylene, galvanized steel, polybutylene, polypropylene, or stainless steel.
Not be smaller than the diameter of the outlet of the valve it serves (usually no smaller than 3/4").
Shall not reduce in size from the valve to the air gap (point of discharge).
Be as short and as straight as possible so as to avoid undue stress on the valve.
Be installed so as to drain by flow of gravity.
Not be trapped since standing water may become contaminated and backflow into the potable water.
Discharge to the floor, to an indirect waste receptor, or to the outdoors.
Not be directly connected to the drainage system to prevent backflow of potentially contaminating the potable water.
Discharge through a visible air gap (atmosphere) in the same room as the water heater.
Be first piped to an indirect waste receptor through an air gap located in a heated area when discharging to the outdoors in areas subject to freezing, since freezing water could block the pipe.
Not terminate more than 6 inches (152 mm) above the floor or waste receptor.
Discharge in a manner that could not cause scalding.
Discharge in a manner that could not cause structural or property damage.
Discharge to a termination point that is readily observable by occupants because discharge indicates that something is wrong.
Be piped independent of other equipment drains, water heater pans, or relief valve discharge piping to the point of discharge.
Not have valves anywhere.
Not have tee fittings.
Not have a threaded connection at the end of the pipe so as to avoid capping.
