Our testing capabilities include a full spectrum of USEPA test methods and other relevant methodologies to provide comprehensive test programs and services such as:

  • Permit Compliance Demonstrations
  • Relative Accuracy Test Audits (RATA’s)
  • Performance Guarantees
  • Trial Burns
  • Process Optimization
  • Flue Gas Acid Dew Point & SO3 Determinations
  • Control Equipment Capture / Removal Efficiency Determinations
  • CEMS Initial Certification
  • PM-CEMS Relative Response Audits/ RCA
  • Combustion Turbine Tuning
  • Method Comparison Testing
  • Liaison – Client/Regulatory Agencies

Serviced Industries Include:

  • Coal-fired & Natural gas fired power plants
  • Primary & Secondary Aluminum Smelters
  • Foundries
  • Food Processing
  • Petroleum Refineries
  • Portland Cement
  • Various other processing & manufacturing plants

Our experience and capabilities include:

  • Reference Method testing for particulate emissions (PM, PM10, PM2.5, CPM, POM), gaseous emissions (SO2, NOX, CO, THC, O2, CO2, H2S, HCl/HF), as well as a variety of source-specific organic and/or inorganic compounds.
  • Testing programs that typically consist of full-spectrum testing services including, but not limited to: testing objectives, test design, operational requirements, regulatory agency notification and liaison, QA/QC, sample collection and analysis, and report preparation.
  • Testing for Hazardous Air Pollutants (VOCs, Semi-VOCs, toxic metals, toxic organics). We have conducted HAPs testing programs for incinerators, kilns, industrial furnaces, RCRA facilities (Part B permits), RCRA and TSCA Trial Burns, and EPA Information Collection Requests (ICRs).
  • Managing projects to meet USEPA Relative Accuracy Test Audit (RATA) requirements. These projects typically utilize instrumental methods for SO2, NOX, CO2, PM, Hg, and flow.
  • Reporting utilizing EPA’s Electronic Reporting Tool (ERT).
  • Performing Visible Emissions Evaluations (USEPA Method 9).
