Narrative:
Directives require a landline coordination call between TRACON and local control at chattanooga approach on every MSAW alert observed. I estimate that between 50% and 70% of all arrs to runway 20 at cha generate a false MSAW alarm due to incorrect equipment settings or parameters. Due to the excessive number of coordination calls generated; I believe unsafe situations are occurring continuously. Override calls cause unnecessary confusion; distrs and frequency congestion which breaks a controller's concentration.

Title: A CTLR AT CHA TRACON BELIEVES THAT A RECENT REQUIREMENT TO NOTIFY TWR WHENEVER AN MSAW ALERT OCCURS CREATES UNNECESSARY WORKLOAD FOR THE APCH CTLR.
Narrative: DIRECTIVES REQUIRE A LANDLINE COORD CALL BTWN TRACON AND LCL CTL AT CHATTANOOGA APCH ON EVERY MSAW ALERT OBSERVED. I ESTIMATE THAT BTWN 50% AND 70% OF ALL ARRS TO RWY 20 AT CHA GENERATE A FALSE MSAW ALARM DUE TO INCORRECT EQUIP SETTINGS OR PARAMETERS. DUE TO THE EXCESSIVE NUMBER OF COORD CALLS GENERATED; I BELIEVE UNSAFE SITUATIONS ARE OCCURRING CONTINUOUSLY. OVERRIDE CALLS CAUSE UNNECESSARY CONFUSION; DISTRS AND FREQ CONGESTION WHICH BREAKS A CTLR'S CONCENTRATION.
