Stationary Source Emissions

Stationary Source Emissions

Experience is what matters when dealing with the varied and challenging gas-matrices of stationary sources. With over 25 years of experience source testing and on-site analytical capabilities, our scientists are able to provide robust analytical solutions for the most challenging projects. Montrose Environmental Group provides analytical and consulting support for over 1,600 stack tests annually.

Our company routinely assists the state and federal regulatory bodies in the refinement of existing test methods and development of new test methods, such as: EPA Other Test Method 29 (OTM-29) Sampling and Analysis for Hydrogen Cyanide Emissions from Stationary Sources and EPA Alternative Test Method 100 (ALT-100) Canister Sampling with Method 18 for Flares.

Unique and challenging test programs are jointly addressed with the laboratory, stack tester, and end-user in order to develop source and analyte-specific sampling and analytical procedures that will hold up to regulatory scrutiny.

We have over 25 years of experience with EPA particulate methods and perform over 10,000 unique gravimetric measurements annually. From PM2.5 to non-sulfate particulate matter and everything in between, our researchers utilize evaporation chambers and desiccators during testing, and they have the ability to obtain gravimetric weights as low as 0.00000 grams on a 6-place balance.
We can provide uniquely labeled and packaged tare weighed filters with a single-business day notice for all methods. Each of our gravimetric balances are calibrated daily with the use of NIST traceable challenge weights to ensure quality and consistency across all projects.
We have a broad understanding of today’s modern regulatory environment and the challenges of low level particulate measurements – any lab that claims these methods are simple, doesn’t know how much they don’t know.

Montrose Environmental Group is an industry leader for analyzing samples using EPA volatile organic compound (VOC) test methods. We have been at the forefront of providing analytical solutions for challenging test-programs for over 25 years, from our flagship service of EPA Method 18 design and analysis to on-site EPA Method 320 FTIR support.
VOC testing is complicated – concentration, temperature, moisture, and pressure all affect how VOCs behave in a stack. These four pieces of information are critical to media selection, whether Tedlar bags, adsorbent tubes, direct interface, or Summa canisters.
Montrose Environmental Group has trained analysts who understand equipment operation in lab and in the field. Equipped with the latest Gas Chromatographs (GC) and FTIR spectrometers, there are very few VOCs we cannot test. Allow us to guide you to the best testing scenario for your situation and utilize experience gained from thousands of in-lab and on-site direct interface jobs.

Our High-Pressure Liquid Chromatography (HPLC) group specializes in EPA inorganic methods. Montrose Environmental Group boasts method detection limits lower than the industry average and has been a part of regulatory compliance tests nationwide. Our experts have assisted the EPA with the refinement of certain methods and pushes for their continual improvement.

With state-of-the-art HPLC instruments outfitted with a variety of detectors, the ability of our analysts to take HPLCs into the field for same-day measurements, and a greater than 90% Stationary Source Audit Program (SSAP) pass rate, Montrose Environmental Group is the logical choice for your next inorganic test program.

EPA Methods:

The modern laboratories of Montrose Environmental Group, Inc. are generously equipped to handle a wide range of air test methods including state specific, OSHA, NIOSH, or custom methods.  While many labs focus on more commonly requested methods, we take a more holistic approach to air testing and if your test program requires an unusual or custom method, nobody is more qualified to assist you.

EPA Methods:
• ALCOA 1470/1471, BAAQMD ST-1B, BAAQMD 45, CARB 421, CARB 421, NIOSH 7903, NIOSH 7904, NJATM 1, Radiello 130 Solvent Analysis

ASTM International has been developing and writing air test methods for over 40 years.  With exacting standards, rigorous QA/QC measures and regular updates, these methods have been widely accepted tools for air compliance programs.  While ASTM is not a regulatory body, their methods are recognized internationally and often used to demonstrate compliance.  With a global footprint, using ASTM methods allows for method transfer and harmonization across facilities.

ASTM Methods:
• D1945, D1946, D3792, D6348, D6735

The National Council of Air and Stream Improvement (NCASI) has maintained itself as an independent non-profit research organization founded by the wood products industry in 1943.  In the absence of adequate air and water test methods relevant to the analytes and source types found at wood products facilities, NCASI began developing and publishing air and water test methods in the 1990s.

Our people have been proactive in understanding, executing and adding these methods to our NELAP scope of accreditations as they become available.  We have developed a thorough understanding of the in-lab and in-field performance measures for each method which help validate a test program.

The NCASI Methods primarily focus on the sampling and analysis of alcohols (methanol, phenol) and aldehydes (formaldehyde, acetaldehyde, acrolein, propionaldehyde).  The suitability of NCASI test methods goes beyond wood products facilities, and they are often used for engineering as well as compliance testing.

Reliable, fast and versatile – those are just three advantages to the on-site testing services of Montrose Environmental Group. As facilities demand immediate results for complex and highly scrutinized test programs, the ability to perform on-site testing from an accredited mobile lab is a powerful tool. Our field services include Fourier transform infrared (FTIR) spectroscopy, gas chromatography (GC), high pressure liquid chromatography (HPLC) and spectrophotometry (SPEC).

Montrose Environmental Group mobilizes highly trained laboratory analysts to perform on-site testing throughout the United States and internationally.  Our analysts have the ability to setup, calibrate, troubleshoot and repair equipment in the field as necessary. While we cannot foresee problems that may arise in the field, we can mobilize equipment and staff capable of addressing these problems head on.  We provide experienced personnel who ensure a successful project the first time.
