Narrative:

Aircraft X taxied into position and hold on runway 24L. Socal TRACON stopped departures for an smo departure; noise abatement procedure. Aircraft X sat on the runway for 15 mins while we waited for sct to release the departures at lax. The noise abatement procedures at smo airport have the smo departures initially fly towards the departure path of lax. This causes excessive delays for lax departures; sometimes the aircraft hold in position. Also; lax arrs are not protected from smo departures if they go around. Smo departure should fly a heading of 270 degrees after departure instead of the 210 degree heading they fly now. This happens multiple times daily.
