Narrative:
The flight had been level for some time at the published altitude 11000 ft. I reduced his speed to 220 KTS and issued crossing traffic climbing to 10000 ft. The flight crew acknowledged the traffic and began descending into him. I do not believe we ever had less than standard separation; but I would love to know why a pilot would ever descend into traffic he just acknowledged.this is one of a constant stream of pilots that fail to comply with the published crossing altitudes on the new oapm [optimization of airspace and procedures in the metroplex] procedures. They [the procedures] need to be immediately terminated until the real source of the problem can be identified and corrected. This is a safety hazard.
