emission standards is achieved if visible emissions do not exceed the
applicable visible emission limitations in
26.11.30.05B(1) or
(2) as applicable.

(6) The owner or operator of a municipal
waste combustor that is required to install and operate a COM is subject to the
following requirements:
(a) The owner or
operator of a municipal waste combustor may not cause or permit the discharge

compliance with COMAR
26.11.08.04 when using a COM,
emissions that are visible to a human observer are those that are equal to or
greater than 10 percent opacity.
(c) For the owner or operator of a municipal
waste combustor that is required to install and operate a COM, compliance with
visible emission standards is achieved if visible emissions do not exceed 10
percent opacity for a 6-minute block average during the unit's operating
time.
