EXPERTISE
Air Pollution Emission Measurement, Continuous Emission Monitoring, Hazardous Waste Trial Burns, Municipal Waste Incineration, Method Development, Toxic Air Measurements, Indoor Air Quality, Air Permitting, Air Pollution Control

SUMMARY OF EXPERIENCE

            Mr. Powell is responsible for the overall operation of the business, general oversight for the implementation, staffing and support of all projects, and coordination with local, state and federal regulatory agencies.  He has over 31 years experience in air quality project management for many industries.

Mr. Powell has recently managed and completed two complete HAP emission inventory/measurement programs for two separate semiconductor facilities, primarily focusing on the measurement and control of VOC, inorganic acid and alkali emissions. A recent project was a three-year test annual program measuring emissions from a large state-of–the-art municipal wastewater treatment facility with an associated fertilizer manufacturing facility; including development of sampling and analytical strategies for the measurement of emissions and air pollution control efficiency for odor causing substances, including reduced sulfur compounds and non-methane hydrocarbons (NMHC) from multiple sources including pump stations and primary and secondary digesters utilizing continuous monitoring techniques over 24-hour periods.  Visible emissions from two combustion turbines were also evaluated during this test program.  In addition, emissions of particulate, SO2, TRS, metals, NMHC and CO were determined from process dryers w/ associated RTOs at the fertilizer facility.

Mr. Powell has performed a number of complex emission inventory programs, including  multi-source HAPS inventories for semiconductor manufacturers analyzing a number of organic and inorganic compounds; full emissions inventory/measurements for a pre-heater cement kiln firing various fuels, as well as a simulated accidental release scenario test program for an integrated pulp and paper mill measuring numerous NCG sources throughout the mill during a planned  "emergency shutdown" procedure.  Data were used to calculate mass emissions of NCG (TRS and VOC) in the event of an actual emergency shutdown. 

            Other past significant projects included numerous Hazardous Waste Trial Burn Program under 40 CFR 64/65 to determine the suitability of cement kilns for the firing of hazardous waste for heat recovery purposes.  These programs involve RCRA Part B permit application preparation, process and air pollution control engineering and evaluation, BACT analyses to replace the existing air pollution control technology and emission and process measurements to determine destruction and removal efficiencies of the kilns for volatile and semi-volatile POHC, PCDD-PCDF, heavy metals and chlorides. These programs involved the measurement of numerous organic and inorganic compounds utilizing a wide assortment of US EPA, SW-846 and ASTM test methods to determine mass emission rates then utilized for modeling and risk assessment purposes. Other past projects include emissions monitoring from batch chemical processes in the pharmaceutical industry utilizing on-line gas chromatography and FTIR, validation of an instrumental test method utilizing Gas Filter Correlation Infra-Red (GFCIR) technology to determine Hydrogen Chloride (HCl) emissions from cement kilns and data gathering for US EPA to develop emission standards for lime kilns.

            Mr. Powell has managed a number of other projects include industrial boiler performance and optimization programs for pulp and paper mills; evaluation of air pollution control technologies and start-up shakedown and compliance demonstration of newly installed air pollution control systems at three facilities for a major web offset printer; air pollution control trouble shooting and consulting services for a major producer of photographic films using a regenerative thermal oxidation VOC control system to control emissions from seven coating lines;  and a complete process and emission evaluation for air pollution control for a secondary aluminum furnace under a state order, resulting in demonstration of compliance through process changes rather than the installation of hardware as required by the regulatory agency.

            Formerly Manager of Environmental Measurements for a nationally recognized environmental consulting firm before forming APCC in 1988, Mr. Powell served as project manager or project scientist/field crew chief in EPA standards development programs for the pigments and stabilizers industry (cadmium), municipal solid waste industry, plywood veneer industry, glass industry (arsenic), process-fired heaters, and industrial boilers.  He has completed comprehensive emission test programs involving multiple sources and numerous different test methods for major manufacturing firms.  Testing in these programs covered organics, acids, metals, and other volatile organic compounds as well as criteria pollutants.  He was involved in developing sampling methods (Methods 25 and 5X) for the EPA for the plywood veneer industry.  In addition, Mr. Powell has previous experience as an environmental technologist, with responsibilities in project management of emissions testing and industrial hygiene.  Experience included source sampling, industrial hygiene, odor, ambient air monitoring and dispersion modeling.

Brett T. Smith

Principal Engineer

EXPERTISE
Air Pollution Emission Measurement, Indoor Air Quality Measurement, Mold, Fourier Transform Infra-Red (FTIR) Spectroscopy, Pulp and Paper

SUMMARY OF EXPERIENCE

            As Principal Engineer at APCC, Ltd, Mr. Smith is responsible for the development, implementation, and support of air quality projects, as well as coordination with local, state, and federal regulatory agencies.  Since joining the firm in 2003, he has developed and assisted with projects involving the measurements of pollutants from industrial boilers, gas turbines, cement kilns, hot-mix asphalt plants, semiconductor manufacturing processes, metal plating processes, and many other source categories, as well as VOC destruction efficiency and RATA test programs. 

            Brett’s primary expertise is in the use and maintenance of continuous emission monitoring instrumentation, including 40 CFR 60 Reference Methods.  He has become an expert in the utilization of Fourier Transform Infrared Spectroscopy (FTIR), utilizing this real-time measurement technology to determine emissions of organic and inorganic compounds from numerous industrial sources including:  semiconductor manufacturing, food processing, batch chemical operations, printing and coating as well as cement manufacturing.

Mr. Smith has recently served as Project Engineer and completed a three-year test annual program measuring emissions from a large state-of–the-art municipal wastewater treatment facility with an associated fertilizer manufacturing facility.  APCC worked with its client to develop sampling and analytical strategies for the measurement of emissions and air pollution control efficiency for odor causing substances, including reduced sulfur compounds and non-methane hydrocarbons (NMHC) from multiple sources including pump stations and primary and secondary digesters utilizing continuous monitoring techniques over 24-hour periods.  In addition, emissions of particulate, SO2, TRS, metals, NMHC and CO were determined from process dryers w/ associated RTOs at the fertilizer facilities.
