Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a waste monitoring device that is properly compatible with a specified value changing according to an operation condition of a coal-fired power generation unit.SOLUTION: The waste monitoring device 62 monitors the concentration of an exhaust gas, which is discharged from the coal-fired power generation unit 1 to generate power by burning of a combustion boiler 32 using an oil-based fuel and coal fuel. The device includes: a threshold acquisition means 623 for acquiring an alarm threshold corresponding to the current condition of operation from a threshold DB 624 for storing an alarm threshold calculated by an exhaust gas specified value corresponding to the operation condition of the coal-fired power generation unit 1; a comparison unit 625 for determining whether the concentration of the exhaust gas discharged from the coal-fired power generation unit 1 exceeds the alarm threshold acquired; and an alarm 626 for generating an alarm on the condition that the concentration is determined to exceed the alarm threshold.
