Resource
Recovery Facility: Emissions Data
Today's
data
The composition of the gases generated in each combustion
unit are sampled every ten seconds. This is referred to as "continuous
emissions monitoring," or CEM. The numbers shown on our data pages
are hourly averages. Recent month's CEM reports are archived
online.

The Resource Recovery Facility must comply with the requirements
of Maryland Department of the Environment (MDE) Permit # 24-031-01718, as
well as Federal standards. Under this air quality permit, the following
limits must not be exceeded:

Operating Indication:
Furnace Roof Temperature 1100 to1600 °F, which corresponds approximately
to furnace temperatures of 1800 to 2300 °F, respectively. When a unit
is shut down, it takes hours for the temperature to decrease to ambient levels.
