Narrative:
We were cleared for the B/C approach into santa maria (smx). We had just reported camco intersection (DME) and were IMC when an small aircraft reported he had the airport in sight and was one mi east. The controller gave the small aircraft an immediate turn away from us. The small aircraft had entered the air traffic area without clearance while it was IFR. We never saw the small aircraft. When we descended through the cloud deck, tower advised small aircraft pilot to call tower.
