The Nine matrix details the possible Nine amounts for inspectors and emissions inspection stations when violations are committed. The chart categorizes Nines as covert (for covert audits) and non-covert (for overt and other audits). In all cases, a fourth violation during covert audits will result in station and inspector license revocation. Non-covert audit Nines are the same for inspectors and stations, and range between a minimum of $100 for a Nirst offense and a maximum of $2,500 for a fourth offense.
