Why Air Toxics Testing (Multimetals, Hex Chrome & Dioxin/Furans) Is Critical in California — And How Energy Environmental Solutions, Inc. Helps Industries Stay Compliant

California maintains some of the most stringent air quality regulations in the United States. As environmental standards continue to evolve, industrial facilities are under increasing pressure to accurately measure and report emissions of hazardous air pollutants (HAPs) and toxic air contaminants (TACs). Accurate Air Toxics Testing is no longer just a regulatory requirement—it is a critical component of environmental compliance, risk management, and operational excellence.

For facilities operating under air permits, comprehensive testing for multimetals, hexavalent chromium (Hex Chrome), and dioxins/furans helps demonstrate compliance with permit conditions, supports public health protection, and provides regulators with reliable emissions data.

At Energy Environmental Solutions, Inc. (EES), we help industries develop testing strategies, perform compliant emissions testing, and prepare defensible reports that satisfy EPA, CARB, and local California Air District requirements.

What Is Air Toxics Testing?

Air Toxics Testing measures hazardous pollutants emitted from industrial sources that may pose risks to human health and the environment.

Common pollutants include:

Multimetals (Arsenic, Lead, Cadmium, Mercury, Nickel, Chromium and others)
Hexavalent Chromium (Cr(VI))
Dioxins and Furans
Hazardous Air Pollutants (HAPs)
Toxic Air Contaminants (TACs)

Testing is generally conducted using approved EPA reference methods under carefully controlled quality assurance procedures to ensure accurate and defensible results.

Why Is Air Toxics Testing So Important in California?

California agencies continue strengthening programs that reduce exposure to toxic air contaminants. Industrial facilities are expected to provide high-quality emissions data to support permitting, health risk assessments, and ongoing compliance.

Recent regulatory developments include:

Stronger Controls on Hexavalent Chromium

California continues implementing stricter requirements for hexavalent chromium emissions from chrome plating and related industrial operations. New control measures, enclosure requirements, and a long-term phase-out schedule are increasing the importance of accurate emissions testing and documentation.

Greater Focus on Toxic Air Contaminants

California air districts continue updating rules and guidance addressing toxic air emissions and community health risks. Facilities are expected to demonstrate compliance through reliable testing and well-documented reports.

Increased Expectations for Data Quality

Regulators continue emphasizing technically defensible emissions data supported by comprehensive Quality Assurance/Quality Control (QA/QC) procedures, proper calibration, and validated testing methods.

More Detailed Compliance Reviews

Environmental agencies increasingly review source test reports, calculations, operating conditions, and laboratory documentation before approving compliance demonstrations.

Current Industry Trends

Today’s environmental compliance programs focus on:

More accurate toxic metals testing
Enhanced QA/QC documentation
Greater emphasis on EPA-approved test methods
Earlier planning before source testing
Improved emissions inventory accuracy
Stronger documentation for inspections
Faster regulatory review through complete reporting
Better health risk assessment support

Risks of Inadequate Air Toxics Testing

Poor planning or incomplete testing may result in:

Delayed permit approvals
Requests for additional testing
Increased project costs
Regulatory comments
Compliance concerns
Extended agency review timelines
Potential enforcement actions

A well-planned testing program helps reduce these risks while supporting efficient project execution.
