Expanding Our Source Testing Support Services: What ALL4’s Addition of Tora Consulting’s Expertise Means for You

Effective source testing requires more than method execution – it also requires understanding the process behind the numbers. With the acquisition of Tora Consulting, ALL4’s source testing (also known as stack testing or emissions testing) support capabilities are stronger than ever. ALL4 has historically paired deep technical expertise in testing methodology and emissions measurement with the regulatory knowledge needed to help clients navigate complex requirements and maintain a defensible position, from initial protocol development through final report submittal. The addition of Tora staff builds upon that foundation at ALL4 by bringing process‑level insight and data‑driven analysis to create a more complete, end‑to‑end support service for clients across every phase of source testing.

A key part of this expanded offering is a proactive approach to high-risk testing. Rather than simply preparing for a compliance test and responding to unfavorable results after the fact, we can evaluate raw materials and process parameters to design an effective engineering study ahead of testing. The goal is to optimize conditions and fully understand the variables that affect emissions before a compliance test ever occurs, reducing risk upfront. These studies can also generate valuable air pollution control device (APCD) design data and operating guidance to benefit facilities long after testing is complete.

That same process-level, data-driven approach carries through into compliance testing itself. Our team works directly with APCD vendors and process engineers during the pre-test phase to identify optimal test conditions and provide real-time parameter monitoring and process operator guidance on the day of testing. On the compliance side, our deep understanding of process data and its influence on emissions provides a strong foundation for justifying operating conditions and method deviations, enabling a defensible, data‑driven position in discussions with regulators.

The result is an emissions testing support team that combines deep methodological expertise with process-level insight and rigorous data analysis, allowing us to support clients from early process evaluation through post-test resolution at every critical step.
