Helping Fleets and Facilities Stay Inspection-Ready

Since 2005, We’ve Built a Reputation on Accuracy, Speed, and Practical Experience.

Founded by Anthony Ferro, Ferro Consulting LLC brings nearly two decades of firsthand experience in emissions compliance, including EPA Method 9 opacity testing and California Clean Truck Check inspections. From dusty job sites to large-scale fleets, we know what it takes to stay ahead of air quality regulations.

Our work isn’t theoretical — it’s built on real enforcement standards, evolving CARB rules, and the realities of the road. Whether you’re a one-truck operator or an industrial facility, we deliver precise, audit-ready testing that helps you operate with confidence.
