I'm thinking of adding it as an air supply on the far side of the shop,
about 150' as we are making additional work cells there.

Can I repair it and get it certified or should I Send it out to be
repaired? *I've seen exploded tanks and I hope to avoid that.

The cheapest would be to buy another used compressor and use its tank.

Ditto. Good, near-new tanks show up on CL regularly. I've bought 2
very nice 60-gallon tanks for $50 each. The motors or pumps usually
fail much earlier than the tank.
