Wheelabrator Annual CEM Data Reports

About Wheelabrator

Wheelabrator is a waste-to energy facility located in Baltimore City.

Subsequent to the Air Quality Control Advisory Council (AQCAC) meeting on December 11, 2017, Wheelabrator provided an Excel spreadsheet containing the 2017 1-hour average Continuous Emission Monitor (CEM) data. This data is being provided for informational purposes only. Wheelabrator has extensively reviewed the data to ensure validity and accuracy. Any questions about the data or the processes should be referred to:

Data Layout

Columns C-E are the 1-hour averages for SO2, CO, and NOx in lbs/hour (LBS/HR) used to calculate the 8-hour block facility averages.

Column L provides the hourly stack flue gas flow rate averages (STACKFLOW_1,2,3) in dry standard cubic feet per minute (DSCFM) used to calculate lbs/hour averages. These averages have been calculated in accordance with the approved PSD monitoring methodology incorporated into the TV permit for determining compliance with the facility wide PSD permit limits.

Columns F, H and I provide the 1-hour averages for SO2, CO, and NOx in ppm corrected to 7%O2 (PPM7%O2). These hourly PPM7%O2 averages are used to calculate SO2 24-hour geometric averages, NOx 24 hour daily arithmetic average and CO 4-hour block arithmetic averages in accordance with Large Municipal Waste Combustor requirements of 40 CFR 60 Subpart Eb/Cb as incorporated into state regulations and TV permit. Column G provides the hourly SO2 Removal Efficiency (REMRPT_1,2,3) reported as a percentage (PERCENT). Columns J and K provide hourly averages for boiler steam flow (STMRPPT_1,2,3) in thousand lbs/hour (KLBS/HR) and ESP inlet temperature (ESPTMP1,2,3) in degrees Fahrenheit (DEG F).

Cells marked "Invalid" indicate that a valid hourly average was not obtained due to CEM malfunction or calibration problem and subsequent corrective actions and/or during performance of required quality assurance activities including routine preventative maintenance and quarterly cylinder gas audits (CGA). The corresponding reason for Invalid data is found in Column M Comments.

Hourly averages that are marked "Offline" indicate that the boiler had been shut down and was offline.
