Stack Testing and Air Pollution Emissions Monitoring Services
From ISC Environmental Consultancy Services
An intense focus on air pollution emission services allows ISC to provide clients with the highest level of technical expertise when confronted with environmental compliance and air pollution control issues. Services include isokinetic stationary source sampling for particulate, acid gases, dioxins and heavy metals, continuous emission monitoring, ambient and indoor air monitoring, and analytical laboratory services.Complying with air quality guidelines is one of the key issues that small and large firms face today. Staffed by professionals with diversified capabilities in engineering and the physical sciences, ISC has the expertise and resources to accomplish your goals ranging from meeting regulatory deadlines to anticipating future environmental programs. Routinely conducting compliance emission test programs enables ISC to provide the level of quality that surpasses the rigorous technical testing requirements.
Routine Stationary Source / Stack Sampling
Capable of performing any type of stationary source test program, ISC routinely conducts source emission test programs for local regulatory compliance. These programs are conducted employing all EPA Reference Methods as well as state-specific procedures.
ISC Source Sampling Group routinely provides testing services for the following:
- All Particulate and Gaseous Pollutants
- Air Toxics
- Dioxins/Furans, PCBs, PAHs, Semi volatiles, Pesticides
- Metals, Hexavalent Chromium, Mercury Speciation
- PM10, Particle Sizing and Characterization
- Aldehydes and Ketones
- Nonmethane Hydrocarbons by EPA Method 25
- Capture and Destruction/Removal Efficiency
- 3-D Flow Profiles
Continuous Emission Monitoring
ISC operates several Mobile Continuous Emission Monitoring (CEM) Laboratories providing on-site, real-time analysis for both source emission and ambient test programs. To ensure data quality and optimize data capture, these laboratories offer a wide variety of instrumentation housed in a controlled environment.
In line with these capabilities, ISC also provides performance specification (PST) testing, relative accuracy test audits (RATA), and calibration gas audits (CGA).
ISC’s specific CEM services include:
- Mobile CEM Laboratories
- Real Time Measurement of SO2, CO, NOx, THC/VOC, O2/CO2
- CEM Certification and Auditing
- On-Site Data Analysis
- Simultaneous Multisource Monitoring
- Part 75 Electronic Data Reporting
Specialized Stationary Source Sampling
ISC routinely performs source test programs requiring specialized equipment, techniques and methodologies. Programs are conducted for evaluation or compliance on sources of extremely high temperature and pressure. Other programs involve determinations of complex organic species for which no sampling or analytical methodology is currently available.
Some typical areas for which specialized programs have been developed include:
- High Pressure/High Vacuum Sources
- High Temperature Sources
- Particulate Laden Gas Streams
- Combustion Zone Analysis
- Multi-Phase Streams
- Explosive Gas Streams
- Radiation Sources
- Simultaneous Multisource Sampling
- Pathogenic Organism Emissions
- Silicon and Mercury Speciation
- Spiking Techniques to Determine Destruction Efficiencies
- Developing sampling and analytical procedures for difficult compound categories such as glycol ethers and amines
ISC has both the ability and experience to design a successful testing program according to your specific needs.
Ambient and Indoor Air Monitoring
The range of Ambient Air Monitoring programs offered by ISC includes Prevention of Significant Deterioration (PSD) determinations, fugitive emission monitoring and air toxics evaluations. Monitoring installation audits and performance evaluations are also conducted utilizing EPA Quality Assurance guidelines.
The principle services that ISC offers include:
- Worker Exposure Evaluations
- Fugitive Emissions
- Criteria Pollutant Monitoring
- PSD Monitoring
- Monitoring Network Audits
- Specialized Monitoring Programs
Leak detection and repair (LDAR)
Regulatory agencies have determined that leaking equipment, such as valves, pumps, and connectors, are the largest source of emissions of volatile organic compounds (VOCs) and volatile hazardous air pollutants (VHAPs) from petroleum refineries and chemical manufacturing facilities. Some agencies have estimated that approximately 70,367 tons per year of VOCs and 9,357 tons per year of HAPs have been emitted from equipment leaks. Emissions from equipment leaks exceed emissions from storage vessels, wastewater, transfer operations, or process vents. VOCs contribute to the formation of ground-level ozone. Ozone is a major component of smog, and causes or aggravates respiratory disease, particularly in children, asthmatics, and healthy adults who participate in moderate exercise.
Some species of VOCs are also classified as VHAPs. Some known or suspected effects of exposure to VHAPs include cancer, reproductive effects, and birth defects. The highest concentrations of VHAPs tend to be closest to the emission source, where the highest public exposure levels are also often detected. Some common VHAPs emitted from refineries and chemical plants include acetaldehyde, benzene, formaldehyde, methylene chloride, naphthalene, toluene, and xylene.
ISC is currently providing leak detection and repair (LDAR) services to industrial facilities. The types of services ISC provided include, but are not limited to:
- Development and implementation of turnkey LDAR programs
- Simple maintenance on leaking components
- Emission calculations and reporting
- 3rd party audits including comparative monitoring
- Internal and external training program development and implementation
- Infrared camera surveys
- QA/QC program development
- Operating procedures and compliance manual development
ISC is uniquely qualified to provide high quality LDAR services due to the extensive training and aggressive QA/QC programs we have developed.
