Narrative:

I was the final controller running 15L/15R visual approaches. 5 miles is required for 15R for the tower due to runway and taxiway closures. Thirty degree intercept turns are required for parallel runway operations for visual approaches. Aircraft X was cleared for a visual approach to runway 15L and the B737 was cleared for the visual to 15R when they joined on the center lines with no belly up situation they were still out side of the 30 degree angle so tarp said it was a 'loss of separation.' this was not an unsafe operation for either aircraft; I believe the 7110.65 change needs to be re evaluated for runways more than 4;300 ft between parallels. It just increases controller and pilot workload unnecessarily.
