How long does HTH chlorine granuals stay good?

I was cleaning out my old shed and found a 20lb bucket of HTH chlorine powder from when I had a pool over ten years ago. It is in the original container with the lid on tight. Is this still good? If not is there any hazardous chemical guidelines to follow to throw it away?

look at the expiration date most of the time this is just a guideline for how long it works the best and is at full strength (not oxidized) you can still use it it just wont work as well.
