Stack Testing Program
Mecklenburg County Air Quality provides oversight of compliance and quality assurance activities related to stack tests performed in Mecklenburg County, North Carolina, as required by permit conditions or state and/or federal regulations. Staff assures proper sampling, analytical methods, and calculations are used to produce accurate air emission data to determine compliance.
Specific activities include: conducting reviews and approvals of stack test protocols, on-site observation of source sampling tests, and review and approval of final emission test reports.
Electronic Reporting Through EPA’s CDX System
Certain industrial facilities are required to submit emissions test results electronically. This can be accomplished by using EPA’s Electronic Reporting Tool (ERT). Facilities should review the applicable regulations with available ERT format to determine the exact requirements for their source. These files are submitted to EPA’s electronic reporting site called the central data exchange (CDX) using the compliance and emissions data reporting interface (CEDRI).
Stack Testing
A stack test, also referred to as a performance or source test, measures the amount of a specific pollutant being emitted; demonstrates the efficiency of a capture system; or determines the destruction or removal efficiency of a control device used to reduce emissions at facilities. Stack testing is an important tool used to determine a facility’s compliance with emission limits, or capture or control efficiencies established pursuant to an applicable emission standard.
