Brett T. Smith

President and Principal Engineer

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

SUMMARY OF EXPERIENCE

            As Principal Engineer at APCC Mr. Smith directly develops, performs, and supervises emissions measurement and air quality projects, as well as coordinating with clients and local, state, and federal regulatory agencies. Mr. Smith had over 15 years of experience in emissions testing before assuming the role of President and overall responsibility for the company's operations in 2019.  

            Since joining the firm in 2003, he has implemented projects involving the measurements of pollutants from industrial boilers, gas turbines, cement kilns, reciprocating internal combustion engines (RICE), printing, hot-mix asphalt plants, semiconductor manufacturing processes, metal plating processes, and many other source categories, as well as VOC capture/destruction efficiency and RATA test programs.

An experienced instrument operator, Mr. Smith has extensive experience in the utilization of Fourier Transform Infrared Spectroscopy (FTIR), to determine emissions of organic and inorganic compounds from numerous industrial sources including: semiconductor manufacturing, food processing, chemical manufacturing, printing and coating, and cement manufacturing. FTIR is a unique method of air testing that is heavily dependent on operator skill in equipment and software setup to yield accurate results. It is particularly useful for exploratory or screening testing because a skilled and experienced operator can often identify and quantify unknown components of the emissions stream on site. See our page on FTIR Capabilities for more details.

In addition to experience in emissions testing, Mr. Smith's expertise also extends to air quality testing in industrial, commercial, and residential environments. Past projects include mold testing in a number of commercial buildings and residences, testing of air quality in industrial environments for comparison to OSHA standards, and investigating employee complaints of poor air quality in commercial and office settings.

John H. Powell

Founder

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

SUMMARY OF EXPERIENCE

            Mr. Powell is founder of APCC, Ltd., and President from 1989 until 2019. During that time, he was 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 40 years of experience in air quality project management for many industries. Currently, Mr. Powell serves APCC in an overall advisory capacity, providing QA/QC oversight for projects and project planning; management of special projects and a limited amount of field measurement work. He is available to all clients on a consulting basis.

Mr. Powell has managed and performed a number of complex emission inventory programs, including an extensive HAPs emissions measurement project for a Carbon Regeneration furnace at a sugar refinery, numerous VOC capture and control projects for printing and coating industries, a multi-source HAPS inventory for a semiconductor manufacturer analyzing a number of organic and inorganic compounds; 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 significant projects included initial PC MACT compliance demonstrations, a number of RCRA Hazardous Waste Trial Burn Programs, emissions monitoring from batch chemical processes in the pharmaceutical industry, validation of an instrumental test method utilizing Gas Filter Correlation Infra-Red (GFCIR) 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 hazardous waste trial burn programs at cement and aggregate kilns. 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.

           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, Mr. Powell served as project manager or project scientist/field crew chief in EPA methods and 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.

Bruce A. Henning

Principal Scientist Emeritus

EXPERTISE
Air Pollution Emission Measurement; Air Permitting, Continuous Emission Monitoring System Design, Installation, Certification, and Operation; Hazardous Waste Trial Burns; Municipal Waste Incineration; and Toxic Air Measurement

SUMMARY OF EXPERIENCE

            As a Principal Scientist at APCC, Ltd, Mr. Henning was responsible for the development, implementation, and support of air quality projects, as well as coordination with local, state, and federal regulatory agencies.  From joining the firm in early 1994 until 2000, Mr. Henning served as the manager of the Portland, ME office.  He now serves in a project level capacity on a part-time basis.

He brings to APCC over 25 years experience in air quality programs for a range of industries that includes manufacturing of pulp and paper, asphalt, cement, aircraft, automobiles, pharmaceuticals and chemicals, as well as metal plating, hazardous waste incineration, resource recovery, utilities, defense, municipal waste water treatment and oil production/refinement.  Under contract to the U.S. Environmental Protection Agency, he has assisted in the development of CEMS regulations and emission factors for AP-42.

            Mr. Henning has managed numerous paper mill wide projects for RATA and compliance emissions testing. He also managed the construction and field installation of a multiple unit continuous opacity monitoring system.  He has performed a number of wet method analyses in the field, providing clients with compliance and diagnostic data within one hour of sampling.  These methods include Chlorine/Chlorine Dioxide, TRS, H2S and Sulfates.  Mr. Henning also managed a test program to determine emissions of polycyclic aromatic hydrocarbons from a thermal oxidation facility at a Superfund site in New Jersey.    

            Formerly Principal of his own environmental consulting firm (1990-1994), Mr. Henning was also employed by two major environmental consulting firms, serving as an air quality scientist.  As such, he was responsible for project management, regulatory negotiation, development of sampling methodology approaches, performance of testing programs, and preparation of air permit applications, proposals, quality assurance plans, and final reports.  Mr. Henning gained substantial experience in trial burns for hazardous waste incinerators, boilers and industrial furnaces.
