Human Factors
I instructed the aircraft to descend to 3;000 and I thought I heard him read back descending to 3;000. I was verifying with another aircraft that he had the new ATIS showing the new landing runway when I should have been turning the A319 to join the localizer. The A319 went across the localizer and as I was turning him back to join from the other side I noticed his altitude was below 3;000 and issued him a climb to 2;600; gave a low altitude alert and a leaving the Bravo advisory. I failed to issue a reentering the bravo airspace advisory. The low altitude alert goes off a lot when it is not a factor but never went off even when the aircraft was 600 FT below the MVA.
CLE Controller described a below MVA event when traffic vectored to the localizer failed to intercept as expected. The reporter also listed a failure to provide exit/entering Class B information during the occurrence.
