separation requirement for residential overhead SE and 'roof' vent

For the below shown situation, what's the minimum horizontal and vertical clearance required between the OH conductors and/or mast and a PVC radon pipe that would extend 12" beyond the roof line (going around the eave, not through).

Prior to the SE being moved, a radon pipe went up and around the eave just left of the vertical gutter drain pipe.

2017 NEC reference would be great... did not see it in 230.9 or 230.24.

Thank you!

Ok, thanks. I'm taking from your comment that there isn't a minimum separation.

SE relocation was two fold... service upgrade to 320 amp service, in conjunction with the original OH SE going almost above the hot tub the prior owner installed... OH conductors are now about 20' shorter, which in my mind, is not a bad thing.
 
A PVC radon pipe as you describe would not be a problem. There is no NEC reference for that. Why was the SE relocated?

Thanks. I ended up routing the exhaust point maybe 1/2" above the eave, after reading some documentation from my state on radon mitigation, and them calling out explicitly that 12" is a guideline that isn't required.
