Where is egr valve located on 2001 Chevy lumina 3.1l?

The EGR valve on a 2001 Chevy Lumina with a 3.1L engine is located on the intake manifold, usually on the passenger side (right side) of the engine. It's often near the back of the intake manifold, making it somewhat difficult to access. You'll likely need to remove some components to get a good view and access to it. A picture or diagram of the engine bay would be helpful in pinpointing its exact location.
