why it matters

Combustion compliance starts with accurate source data

Combustion systems are tied directly to compliance obligations, production reliability and operating efficiency. Without accurate source data, facilities face compliance and reliability risks across regulated engines, boilers, heaters, turbines and control systems.

Meet complex emissions requirements with confidence
Identify combustion issues before they escalate
Support cleaner and more efficient operations
Reduce risk from uncertain emissions data
Verify compliance across regulated source types

Testing combustion sources with precision and purpose

Onterris provides source testing services that help organizations evaluate combustion emissions, verify compliance and understand equipment performance across regulated combustion systems.

Combustion source emissions testing

Onterris helps facilities measure and document emissions from regulated combustion equipment so compliance teams, operators and engineers can make decisions with defensible data.

Permit-required testing for boilers, engines, heaters and turbines
Emissions measurement for flares, incinerators and process combustion systems
Source testing to support compliance demonstrations and operating decisions
Field execution for routine tests and complex stack testing programs

Regulated pollutant measurement

Combustion engineering and emissions profiling

Our teams help clients understand how combustion performance, control equipment and operating conditions affect emissions so they can make informed decisions about compliance and performance.
