Instructions

Sample and analyze the particulate matter collected in the hopper from each bag house or electrostatic precipitator (ESP) 

used to control particulate matter from potlines. Where more than one bag house or ESP discharges solids to a common 

hopper, a single sample will be adequate. In cases where solids from different compartments of a single bag house or ESP 

are collected in multiple hoppers or multiple collection sacks, a single composite sample will be adequate.

If a wet scrubber is used to control emissions from a potline, sample and analyze the scrubber sludge removed from the 

scrubber, and estimate the annual mass (dry basis) of this sludge. In addition, if applicable, sample and analyze the slurry 

injected into the scrubber and estimate the annual mass (dry basis) of the injected slurry. Finally, if there is an aqueous 

discharge or blowdown stream from the scrubber, sample and analyze the this liquid and estimate the annual volume 

discharged.

You must report the results of these chemical analyses in this Microsoft® Excel Emission Test Template. If more than one 

source was tested, you must make a copy of the worksheet and update the source ID in order to distinguish between each 

separate source of particulate matter. After completing the worksheet, you must also submit an electronic copy of the 

emission test report and the chemical analyses. (PDF format preferred).
