Secondary air pump check valve question

With the help of all the great info provided here I removed the secondary air pump from my Spec Boxster. The question I have is, one side of the check valve goes to the carbon canister, where dies the opposite end go if anywhere? During the disassemble of the intake and pump parts I found the check valve and its hose just lying on top of the engine and not connected to anything. Per the drawing in the manual one side goes to the canister. No where in the manuals could I find where the opposite end goes. It may be designed to vent to atmosphere and not be connected to anything on that side of the check valve. I searched in the engine for a place it could go but no luck. Thanks for your help.
