Stack Testing Services Compliance Demonstration | Engineering/Investigative Test Programs | On-Site FTIR Spectroscopy | Specialty Testing | Low Level PM Sampling | Performance Specification Testing (RATA) | International Stack Testing Compliance Demonstration Alliance performs emissions testing to demonstrate compliance with federal, state, and permit-specific requirements, including common pollutants: PM (filterable PM, condensable PM, PM-10, PM-2.5, OTM-37) Metals, including Hg Acid gases Combustion gases Volatile and Semi-Volatile Organics (total and speciated) Dioxins and Furans Formaldehyde Specialty Testing (PFAS, EtO, Combustors) Testing is performed on a wide range of emissions control systems, including: Baghouses, Cyclones, and ESPs FGD and dry scrubbers SCR and NSCR Oxidizers (thermal, regenerative, and catalytic) Engineering & Investigative Test Programs When should a facility consider an engineering or investigative stack testing program? Facilities may consider investigative testing when preparing for a high-priority compliance test or when process-related challenges require accurate emissions data for troubleshooting or performance evaluation. Alliance’s experienced testing professionals can design customized measurement programs that help facilities evaluate control device performance, identify potential compliance risks, and better understand process conditions before conducting formal compliance demonstrations. Our fully integrated consultants are also available to provide subject matter expertise consultations. Performance Specification Testing (RATA) Alliance provides Part 60, Part 63, and Part 75 continuous emissions monitoring system (CEMS) evaluations and relative accuracy test audits (RATA) for all manner of CEMS configurations within all applicable industries. From routine gas and flow RATAs to highly complex GC, PM and Mercury RATAs, we have you covered. Precision Flow™ RATA Testing Traditional Method 2 flow testing can introduce measurement bias that affects reported mass emissions. Alliance's Precision Flow™ program uses automated electronic flow measurement techniques based on EPA Methods 2G and 2H to deliver more representative flow data, reduce testing variability, and complete most Flow RATAs in approximately one hour per load condition. The result is greater confidence in your emissions reporting with minimal impact to your testing schedule. Specialty Stack Testing Capabilities One of Alliance’s key stack testing differentiators is our ability to plan and execute testing programs for the most complex emissions targets and scenarios. Our capabilities include: Dilution Based Sampling for Particulate Matter (OTM-37) PFAS Sampling (OTM-45 & OTM-50) Diluted CEMS Sampling for High Moisture or Highly Concentrated Sampling Locations Direct Interface Gas Chromatography for Speciated VOC and Sulfur Compounds OOOOb Combustor Compliance Testing (OTM-52) Hazardous Waste Combustion CPT Programs Low Level Particulate Matter Sampling How does Alliance measure extremely low PM levels? As compliance thresholds for PM, PM-10, and PM-2.5 continue to decrease, you need a highly experienced testing partner to create a testing plan to mitigate the challenges associated with accurately quantifying very low levels of particulate matter. Alliance ensures accuracy with advanced equipment, a fully developed internal laboratory network, and rigorous quality control procedures. On-Site FTIR Spectroscopy Alliance provides on-site Fourier Transform Infrared (FTIR) spectroscopy for complex emissions measurement applications, including low-level hazardous air pollutants and multi-compound gas streams. Our FTIR specialists support compliance demonstrations for pollutants such as formaldehyde, ethylene oxide, and hydrogen chloride. International Stack Testing International stack testing is full of challenges — but they can be solved with the right approach. Alliance has developed a system that keeps your projects on track, from ensuring accuracy under pressure to moving equipment securely across borders to planning every detail in advance.
