Aircraft X was on a visual approach to OAK RWY 30 with Aircraft Y following on the visual approach. A VFR 1200 code aircraft departed HWD southeast bound and was climbing. I issued traffic to Aircraft X on the 1200 code as it appeared to climb out of 1100 feet. The 1200 code aircraft climbed to 1400 feet. Aircraft X passed over the aircraft at 2500 feet on a seven mile final. I then switched Aircraft X to OAK Tower. He eventually went around. I issued traffic to Aircraft Y on the 1200 code aircraft. When Aircraft Y did not have the aircraft in sight I instructed him to stop his descent as the aircraft passed underneath. Once Aircraft Y passed I cleared him for the visual.The 1200 code aircraft was on a path directly underneath the OAK RWY 30 final and opposite direction. The aircraft was inside HWD delta airspace the entire time. This leads me to believe that the aircraft is in communication with the tower at this point. Our LOA with HWD Tower states that OAK RWY 30 aircraft may penetrate the class delta airspace without coordination provided they are within 1.5 nm of the centerline. We have been told by controllers and FLMs at HWD Tower that they are under direct order not to issue turns to aircraft. If this is the case it contradicts the 7110.65 and has caused numerous cases like this and is causing unsafe situations that will ultimately lead to a midair collision.Management and [union reps] from both facilities need to get together and collaborate on a way to mitigate this unsafe practice.
NCT TRACON Controller reported a VFR aircraft in HWD airspace flew under the OAK Runway 30 final approach course causing two conflicts with OAK arrivals. The final approach course goes through HWD Delta airspace.
