It looks to me that the previous owner has either left it off by mistake or taken it off on purpose,if its blocked off at the end its most likely been done on purpose,(perhaps the Egr was faulty,Ive done this to mine.
As long as its blocked off it should run fine & you wont get so much carbon inside the Throttle bodie.

The egr valve puts exhaust gasses back into the intake. The PCV valve puts it's gasses back into the air flow before the TB. At least that's how it is on my 3.slow.

When the egr is a little dodgy it doesnt close & the engine chokes a bit on this carbon air,causing a rough idle sometimes.
Put it this way if you are a smoker ,how would you like the smoke you blow out to be feed back though you by some tube in your neck.

the EGR is used when cruising on the highway or any light throttle, light load conditions, because the engine usually runs lean at those times, NOX is produced, its a emission, the egr lets exhaust gases into the intake to help cool off the combustion chamber to reduce NOX emissions, the exhaust gasses contain very little oxygen so it does not burn, thus lowering combustion temps

Just a little off topic... It's all about cleaner emissions though right EGR... less NOx, Tunnels... Less brown trout

a properly working EGR valve will also get you better mileage since you're not dumping as much air/fuel mix into the combustion chamber. it's more important to have on a 22RE than it is on a 22R because the 22RE tends to run leaner, and a leaner mixture runs hotter. the EGR helps cool this down and prevent detonation
as for mine, it's blocked off, and i'm blocking off the EGR setup on my new engine that's going in. why? i don't have the complete emissions setup, we don't have testing here, and the whole setup seems needlessly complicated. if there was 1 hose from the carb to the EGR valve, i'd run it in a heartbeat, but noooo...

I just noticed this today also, anyone have an idea what the nipple connects too? It has suction to it so its meant for something. Is that the coolant temp sensor?
