Expert Testimony

Source is best known for performance of superb air quality services.

Air quality services range from identifying air emissions and preparing complete permit applications, all the way to helping clients comply with complex permit requirements. The founder of Source has been continuously associated with air quality matters since before the original Clean Air Act was adopted in 1967. This association includes personally performing or supervising all technical aspects of air quality services such as air monitoring, stack testing, laboratory analysis, air modeling, control of air emissions, preparation of air permits, negotiations with environmental agencies and testifying as an expert witness.

Atmospheric Dispersion Modeling

Source prepares atmospheric dispersion modeling studies when required for air permit applications or upon request of its clients. These studies are performed to determine if harmful air quality impacts will occur either during routine plant operations or plant emergencies. Source maintains an extensive library of air modeling guidelines, textbooks; and manuals, as well as all EPA approved modeling codes and associated computer software. These modeling codes include standard and special purpose EPA regulatory models, state developed models, vehicle emission models, numerous screening models and various emergency release models. Current modeling information is always available for use by Source via a computer modem connection with the air modeling "bulletin board" of the U.S. EPA .

Air Emissions Inventories

Accurate knowledge of a facility's air emissions is important for regulatory purposes, for determining available emission offsets and for developing permitting strategies.

During the past five years, Source has prepared nearly 200 air emission inventories (including the air emission sections of air permit applications and SARA Toxic Release Inventories). These inventories were for facilities ranging from very large chemical complexes to small manufacturing plants.

Included in the inventories prepared by Source is a determination of fugitive emissions from valves and flanges, speciation of chemical compounds, size distribution of particulates, and calculation of emissions from storage ponds and related wastewater facilities. In-house developed computer software with comprehensive spreadsheets is used to calculate and to display facility air emissions. Preparation of process flow diagrams, material balance tables and detailed reports describing all calculations is included in Source's inventory services.

Ambient Air Monitoring

The Source staff can manage or perform ambient air monitoring for all criteria air pollutants, as well as for non-criteria and hazardous air pollutants. Source works with associated firms to set up and maintain continuous monitors in the field. On these projects, Source performs the data reduction and processing services by reducing data From strip chart recorders, as well as from digital data loggers. As part of its monitoring services, Source also performs community noise exposure studies by integrating sound level meters, meteorological equipment and data loggers. Statistical summaries, pollution roses and wind roses are also prepared from data collected during monitoring efforts.

Air Emission Control Technology

An analysis of air emission control devices, called a Best Available Control Technology (BACT) analysis, is required for most air permit applications. Through continuous review of pertinent literature, frequent contact with equipment suppliers and by use of the EPA "BACT Clearinghouse", the environmental consultants and other specialists at Source maintain up-to-date knowledge of the operations, costs and efficiency of all currently available air emission control equipment. The Source environmental consultants and scientists pride themselves on being ahead of other consultants and environmental agency personnel in their knowledge of new developments in air emission control technologies. Other engineering and consulting firms often use Source consultants to prepare the BACT portion of their air permit applications.

Air Emission Source Testing and Continuous Emissions Monitoring

SOURCE performs emission source testing using equipment and sampling teams located in Houston, Texas or by use of Tracer Technology sampling teams located in San Marcos, California, or by working with associated stack sampling firms. Source and its associates have performed stack sampling projects for numerous emission sources, including chemical plants, asphalt batch plants, power plants, cement plants, wood mills, incinerators, cogeneration facilities, refineries, smelters and electroplating plants. The pollutants monitored include particulates, oxides of nitrogen, carbon monoxide, sulfur dioxide, sulfuric acid, individual organic carbons, total hydrocarbons and fluorides. All testing is performed in accordance with EPA standard methods and applicable state test protocols. On-time reports are prepared using in-house developed software. In addition to performing emission source testing projects, Source negotiates air permit requirements with agency officials and provides specifications for continuous emission monitoring systems (CEMís).

Air Quality Risk Assessments

Air quality risk assessments of airborne toxic chemical releases are performed by the Source air dispersion modeling staff. These assessments are performed as required by the Emergency Planning and Community Right-To-Know Act or upon requests from clients for emergency planning information. The risk assessment studies include hazard identification and vulnerability analyses by Source emergency response specialists and risk analyses using EPA approved air dispersion modeling procedures. The Source risk assessment procedures comply with the EPA risk assessment guidelines and the reports are presented in language, tables and figures which are tailored for easy understanding by the public.

Fugitive Air Emission Monitoring Services

SOURCE environmental consultants and other specialists perform consulting services related to fugitive air emission monitoring. These services include establishing plant monitoring programs utilizing piping and instrumentation drawings (P&ID) or in-plant line tracing of those components that require monitoring, preparing plant monitoring plans, performing quality assurance of monitoring procedures and defining report formats, as well as assisting clients during agency audits and compliance meetings.

In-plant fugitive emissions monitoring services are provided by the Emissions Control Services (ECS) branch of TEAM. This branch is the nation's leader in plant emissions identification, control, monitoring and maintenance. The ECS branch is also very active in developing plant specific emission factors for leaking equipment components by performing "bagging studies" at many chemical plants. These studies typically result in significantly lower reported emissions from the chemical plants than would be reported using standard emission factors.
