McHale Environmental understands the complexity of the issues faced by industries. McHale has the experience and expertise to help resolve federal, state and local compliance issues for owners of emission sources.
McHale Environmental offers extensive experience and expert knowledge of the manual testing, instrumental testing and CEMS testing methodologies that are used to determine facility's emissions. Our lab/CEMS trailers are capable of sampling from multiple locations continuously and simultaneously, using the latest available equipment. Our equipment is maintained and calibrated to meet all EPA QA/QC standards. We have an excellent inventory of CEMS and manual equipment. The emissions team has 25 years experience performing EPA manual methods, on many types of sources, with an emphasis on high quality results in a timely manner. We are expert at performing multiple manual test trains simultaneously.
Manual Testing Methods include EPA Reference Methods, State test methods, ASTM, NCASI, and international methodologies. The manual test generally involves collecting a sample either isokinetically or at a constant rate, analyzing the sample for the tested compound, and determining the concentration and or emission rate of the compound in question, using the measured and or recorded process information. Hundreds of manual test methods exist due to the number of compounds found in emission sources. Most test methods are based on the Federal EPA test methods, which are found in the Federal Register under 40CFR60, Appendix A and Appendix B.
Continuous Testing Methods (CEMS) include EPA Reference Methods, State test methods, ASTM, NCASI, and international methodologies. The continuous test (CEMS) generally involves collecting samples continuously by way of a sample pump, removing the moisture and delivering the samples to the continuous emission analyzer. Each analyzer measures one or more constituents. The technique used to measure a compound varies. Most analyzers use infrared or parametric techniques. The measurement is linearized and the output is scaled to accurately determine the amount of the constituent either in ppmvd, ppmvw or % levels. These outputs are recorded real time, averaged and bias corrected to determine the most accurate result for the test period. The emission rate lb/hr or emission concentration lb/MMBtu is calculated by using the resultant emission concentration and the measured process data. Numerous types of CEMS methods exist due to the number of compounds found in emission sources. Most CEMS test methods are based on the Federal EPA test methods, which are found in the Federal Register under 40CFR60, Appendix A and Appendix B and 40CFR75.
Whether facing an initial certification test, compliance/guarantee test, relative accuracy test, audits, we have the experience to perform the required test methods needed.
