Source Testing
Mostardi Platt offers an extensive array of air emissions testing services, including stack testing, FTIR, wet and gaseous sampling, HAP determination, and mercury testing. We proudly support the power generation, oil refining, chemicals, metals, and waste management industries, using advanced technology and regulatory expertise to ensure precise results and compliance with EPA and state regulations.
Wet Testing
Wet testing involves sampling techniques designed to capture pollutants in a liquid phase for later analysis. This method is frequently used to measure pollutants like sulfur dioxide (SO₂), ammonia (NH3), and hydrogen chloride (HCl), which dissolve in water. Industries such as power generation, petrochemical processing, and metal refining often rely on wet testing to ensure compliance with environmental regulations. The accuracy provided by wet testing is essential for capturing emissions with high moisture content that are difficult to assess in dry form.
Isokinetic Wet Testing
Isokinetic testing ensures that the velocity of the gas sample entering the probe matches the velocity of the gas in the stack. This technique is critical for accurately measuring particulate matter and pollutants in applications where uniform gas flow conditions exist. By maintaining equal velocities, isokinetic wet testing provides highly reliable data, especially for sources like power plants, incinerators, and industrial boilers with consistent emissions profiles.
- Particulate matter equal to or less than a nominal aerodynamic diameter of 10 micrometers and 2.5 micrometers (PM 10/2.5 )
- Relative Response Audits (RRA)
- Response Correlation Audits (RCA)
- PS-11 Initial and re-certifications
- Site-Specific Operating Limit (SSOL)
- Total Particulate Matter (TPM)
- Preliminary On-site filterable particulate matter analysis
- Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (D/F)

Non-Isokinetic Wet Testing
Non-isokinetic testing is ideal for scenarios where flow conditions vary or are less critical to the pollutant measurement. This method is often employed for pollutants like SO₂ and HCl, where precise flow matching is not required for accurate chemical analysis. Non-isokinetic wet testing offers flexibility and is especially useful for facilities with unique configurations or intermittent processes.
- HAPs
- TRS
PFAS Testing
PFAS testing refers to the process of identifying and quantifying the presence of per- and polyfluoroalkyl substances (PFAS) in various samples, including air, water, blood, food, and other materials. These tests are crucial for assessing exposure risks, monitoring contamination, and informing regulatory actions.
Gaseous Testing
Gaseous testing measures air pollutants that remain in gaseous form under standard conditions. This includes monitoring emissions of carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO₂), volatile organic compounds (VOCs), and other gases. Industries such as natural gas processing, oil refining, and chemical manufacturing rely on gaseous testing for compliance with federal and state air quality standards. Mostardi Platt provides these essential services through advanced stack testing methods.
Relative Accuracy Test Audits
RATAs are necessary to verify continuous emissions monitoring systems (CEMS) accuracy, comparing CEMS readings to independent, EPA-approved stack tests. Industries with CEMS, such as power plants and refineries, rely on Mostardi Platt’s RATA services to ensure compliance with EPA regulations.
Destruction and Removal Efficiency
Destruction and Removal Efficiency (DRE) refers to the effectiveness of a system (like an incinerator or flare) in destroying or removing pollutants from a gas stream. It's typically expressed as a percentage, indicating the proportion of pollutants that are either destroyed or removed by the system. For example, a DRE of 99.99% means that for every 10,000 molecules entering the system, 9,999 are destroyed or removed.
Temporary CEMS Installations
A temporary CEMS (Continuous Emission Monitoring System) installation is a system used to monitor emissions from industrial processes when a permanent CEMS is unavailable, undergoing maintenance, or for specific short-term projects. These systems ensure continued compliance with environmental regulations during these periods.
Predictive Emissions Monitoring System
A Predictive Emissions Monitoring System (PEMS) is a software-based solution that uses mathematical or statistical models, often powered by machine learning, to estimate emissions from industrial processes in real-time. It leverages existing plant data from various sensors to predict emission levels, offering a cost-effective and reliable alternative to traditional hardware-based Continuous Emission Monitoring Systems (CEMS).
FTIR (Fourier Transform Infrared Spectroscopy)
FTIR is a powerful technique for real-time monitoring of multiple gases simultaneously. By measuring infrared light absorption by various gas components, FTIR offers data on pollutants like VOCs, HAPs (Hazardous Air Pollutants), and greenhouse gases (GHGs). This technology is widely used in sectors such as waste incineration, cement production, and pharmaceuticals, with Mostardi Platt’s FTIR capabilities providing high-precision identification and quantification of complex gas mixtures.
40 CFR 63 Subpart YYYY
This subpart of the Code of Federal Regulations specifies the National Emission Standards for Hazardous Air Pollutants (NESHAP) for stationary combustion turbines, targeting emissions of hazardous pollutants like formaldehyde, acetaldehyde, and methanol from combustion turbines in industries like power generation and petrochemical processing. Mostardi Platt offers comprehensive stack testing services to assist facilities in meeting Subpart YYYY compliance standards, including the use of unique optical filters and thermal oxidation in order to drive detection limits into low double digit ppb ranges.
40 CFR 63 Subpart LLL
This subpart of the Code of Federal Regulations applies to Portland cement manufacturing plants, setting NESHAP standards for this sector to reduce hazardous pollutants, including mercury, hydrochloric acid, and particulate matter (PM). Cement plants undergo regular stack testing to verify compliance, and Mostardi Platt's expertise in testing ensures adherence to these complex regulatory requirements.
40 CFR 63 Subpart EEE
This subpart of the Code of Federal Regulations applies to hazardous waste combustors, including incinerators, cement kilns, and lightweight aggregate kilns that burn hazardous waste. This subpart establishes stringent emission limits for hazardous pollutants such as mercury, hydrogen chloride (HCl), particulate matter (PM), dioxins/furans, and metals. Compliance is demonstrated through regular performance (stack) testing and continuous monitoring. Mostardi Platt’s expertise in emissions testing ensures facilities meet the complex and evolving requirements of Subpart EEE with accuracy and regulatory confidence.
40 CFR 60 Subpart JJJJ
This subpart of the Code of Federal Regulations specifies requirements for stationary spark ignition internal combustion engines (SI ICE), targeting emissions of hazardous pollutants like oxides of nitrogen (NOX), carbon monoxide (CO), and volatile organic compounds (VOC) from engines in industries like power generation and petrochemical processing. Mostardi Platt offers comprehensive stack testing services to assist facilities in meeting Subpart JJJJ compliance standards.
Organic HAP Determination
Organic hazardous air pollutants (HAPs), including benzene, toluene, and xylenes, pose risks to human health and the environment. Mostardi Platt’s stack testing services for organic HAPs employ advanced methods such as gas chromatography and FTIR to identify and quantify these pollutants. Petrochemical, refinery, and manufacturing industries rely on these tests to meet strict emission limits on organic HAPs.
Inorganic HAP Determination
Inorganic HAPs include metals like lead, mercury, and arsenic, as well as non-organic compounds like hydrogen chloride (HCl) and hydrogen fluoride (HF). Emissions from industries such as metal processing, waste incineration, and cement manufacturing are carefully sampled and/or monitored by Mostardi Platt to ensure regulatory compliance with NESHAP standards.
