Sulfuric Acid Mist Sampling and Controlled Condensate (NCASI Method 8a) Testing

Criteria Pollutants and MACT related air toxics such as Mercury and HCl get a lot of attention in the field of air-quality analysis and emissions testing (stack testing), but other, less-known pollutants can and do cause issues for facilities. Sulfuric Acid Mist (H2SO4) is one such pollutant.


Sulfuric acid emissions

Sulfuric acid emissions have traditionally been measured using EPA Method 8. This method utilizes the principle of selective solvent absorption (SSA) and captures sulfur trioxide (SO3) and H2SO4 in an isopropyl alcohol (IPA) solution, and SO3 in a low concentration of hydrogen peroxide. A drawback to this method, however, is that it was developed and originally promulgated to determine SO3/H2SO4 emissions from stationary sources in the absence of other particulate matter. The principal drawback is the absence of a filter to effectively remove PM and other pollutants prior to the capture of H2SO4 in IPA. This can lead to interference from a number of filterable particulates and other pollutants, such as ammonia, and may result in emissions reading much higher than expected, making it difficult to achieve compliance with the emissions standards.


NCASI Method 8a

NCASI Method 8a, originally Conditional Test Method (CTM)-013, was developed as an alternative to EPA Method 8, and uses a heated quartz filter for capturing particulates, thereby eliminating the potential for interference from particulate sulfate and other interference. For sources that are having trouble with obtaining low emissions of H2SO4, and particularly those that have been using ammonia-injection control technology, the use of this method can result in a significant reduction in reported emissions from the source, by removing these varying interferences.

The quartz filter is maintained at temperatures above 500 degrees F, allowing the gaseous SO3/H2SO4 to pass through and be selectively condensed in a temperature-controlled condenser. The condenser cools the flue gases below the dew point of the SO3/H2SO4, but above the dew point of water, eliminating the potential for interference from SO2. The method was developed and validated as an alternative for determining sulfuric acid emissions from combination boilers and recovery furnaces equipped with dry particulate control devices, and tested extensively on kraft recovery furnaces. It was specifically approved by the EPA for use on recovery furnaces in 1996.


Potential Issues

There are two potential issues with utilizing this method. The first is that it utilizes special equipment that not many testing firms have. The equipment costs several thousand dollars, which creates a large up-front cost to conducting tests using this method. The second is that the method is not specifically approved for any units other than recovery furnaces, and compliance tests performed by this method must be approved by state regulators on a case-by-case basis.


Call in the Professionals

ESS, an air-testing firm out of Wilmington, North Carolina, has the equipment and experience to conduct this test method for facilities that are currently or potentially regulated for H2SO4. ESS has requested and received variances from state regulators for use on biomass boilers, paper mills, and ceramic kilns for compliance-level testing. In all cases so far, the use of this alternative method has greatly improved the reported emissions of H2SO4, and helped our clients achieve compliance with the emissions standards their units are subject to.

If your facility is expected to be regulated for sulfuric acid mist, you need a testing partner that can achieve the best results. Give ESS a call today at  (910) 799-1055.

EPA Proposal – Carbon Pollution Standards for New Power Plants

EPA News & UpdatesOn September 20, 2013, the US Environmental Protection Agency (EPA) proposed new Clean Air Act standards to cut carbon pollution from new power plants. The proposed rule is for New Source Performance Standards (NSPS) for new fossil fuel-fired electric generating units (EGUs), primarily those fired by coal or natural gas. The rule was crafted to limit the emissions of carbon dioxide (CO2), from these EGU units.

The proposal is part of the EPAs plans to combat climate change and improve public health. Fossil fuel-fired power plants are the nation’s largest sources of carbon pollution and emissions of Greenhouse Gases (GHGs). The rule is designed to require any newly constructed power plants be equipped during the construction phase with the available best technology for controlling carbon and GHG emissions. EPA is accepting and encouraging public comment on the new proposed standards, and will maintain the comment period for 60 days after the original publish date in the Federal Register.

The proposed standards are, in actuality, a revision of standards originally proposed in April of 2012, and this new proposal is an attempt on the part of the EPA to accommodate the feedback and criticisms from the 2.5 million public comments received after the initial proposed rule. The chief criticism of the original rule was a single standard for both coal and natural gas-fired units, based on a single concept of “best system of emissions reductions” (BSER). In response to this, the new rule proposes two separate standards for coal and gas-fired units, based on BSERs specific to each category. The original proposal was rescinded by the EPA in a separate action.

This NSPS proposed rule is specific to plants that will be constructed in the future, typically identified as after the date of the proposal. After the proposed NSPS standards, the EPA has announced plans to communicate with the owners and operators of currently-constructed sources, to develop standards for existing units. These standards are expected to be different from, and less stringent than, the standards proposed now for future sources.

The Proposed NSPS Standards

    • Fossil Fuel-fired utility boilers and integrated gasification combined cycle (IGCC) units
      • BSER – Partial Carbon Capture System
      • Proposed limits, dependent on compliance period that best suits the unit:
        • 1,100 lb CO2/MWh gross over 12-operating month period
        • 1,000 – 1,050 lb CO2/MWh gross over an 84-operating month (7-year) period
    • Natural gas-fired stationary combustion units
      • BSER – Current Natural gas combined cycle (NGCC) units
      • Proposed limits, dependent on size of the unit:
        • 1,000 lb CO2/MWh gross for larger units (>850 mmBtu/hr)
        • 1,100 lb CO2/MWh gross for smaller units (?850 mmBtu/hr)

Comment Period and How to Comment

EPA will accept comment on this new proposal for 60 days after publication in the Federal Register.

Comments on the proposed standard should be identified by Docket ID No. EPA-HQ-OAR-2013-0495. All comments may be submitted by one of the following methods:

  • – follow the on-line instructions for comment submittal
  • E-mail comments to [email protected]
  • Fax your comments to: 202-566-9744
  • Mail your comments to:
    • Air and Radiation Docket and Information Center
    • Environmental Protection Agency
    • Mail Code: 2822 2T
    • 1200 Pennsylvania Ave. NW
    • Washington, DC 20460
  • Deliver your comments to:
    • EPA Docket Center, Room 3334
    • 1301 Constitution Ave. NW
    • Washington, DC 20460

Air Quality Control in Vietnam

Air Pollution Challenges in Vietnam

Air Pollution Challenges in Vietnam

After 2 months staffed, the Representative Office for Environmental Source Samplers, Inc. (ESS) in Vietnam is excited about the opportunities and challenges in regards to the air quality situation in the country. Air quality in Vietnam in modern times is a significant concern, particularly in Ho Chi Minh city, a primary focus city for government initiatives for sampling and pollution control activities. Ho Chi Minh City has been targeted as a serious air pollution area, due primarily to issues related to industrial production, transportation, and construction.

Air Pollution Challenges

Among the challenges is the high level of air pollution in the inner cities and Suburbs, but there are improvements. Tran Nguyen Hien, Head of the Natural Resources and Environmental Protection Department in Ho Chi Minh City, said the results of air-quality monitoring in 2012 showed improvement from previous years. Concentrations of NOx, benzene, and lead dropped significantly to reach the initial promulgated standards. But dust (particulate) and CO2 concentrations remain higher than the permitted standard. There are a number of reasons for this. In urban areas, concentrations of CO2 typically exceed the targets due to areas with dense traffic and inadequate infrastructure, leading to frequent congestion and traffic jams. In suburban areas, particulate pollution often comes from the manufacturing operations of local businesses.

Mr. Phung Chi Sy, Deputy Director of the Institute of Tropical Technology and Environmental Protection, says that of existing factories, only 10% have exhaust treatment system that satisfy standards. Very few companies invest in gas treatment systems, and for the ones that do the technology is typically outdated, offering no guarantee for meeting emission requirements. Of the remaining companies, many are not interested in the costs related to investing in exhaust or gas treatment systems. Fines are often less than the cost of investment, and so many of these companies will simply choose to pay the fines if infractions are discovered by inspection teams.

Overcoming the Challenges

According to Mr. Tran, the Department of Natural Resources and Environment has submitted to the HCMC People’s Committee a plan for reinvestment and rehabilitation of equipment and systems to control air and surface water, including new investments in surface water monitoring stations and the renovation of two automatic air monitoring stations. At the same time, the Department is working with relevant agencies to accelerate solutions in traffic congestion and infrastructure, including reconstruction of the traffic system in the inner cities. The hope is that this will lead to a decrease in traffic congestion.

In the suburbs, the Department plans to strengthen inspection activities and to levy sanctions against those companies with emissions violations. The first step involves increasing fines on the highest bracket to where they provide a significant deterrent to organizations in violation of the emissions standards. At the same time, the city plans on compiling a registry of the most serious violators, particularly those established in residential areas.

The Department of Environmental Protection believes that their new initiative will provide the basics for a consistent solution to air-pollution, that will maintain consistency even in the event of a significant change of focus or direction in the country’s manufacturing goals. In the long term, the goal is to provide solutions that will bring a future of clean air and healthy atmosphere to the citizens of Vietnam, and Ho Chi Minh City in particular. For experienced distributors of control equipment, and air quality consultancy firms like ESS, it is a new chance to cooperate with and support the city for clean air quality and control.

ESS was established in 1979 and has a history of over 30 years of providing stack testing, and air-quality consulting services, both domestically in the United States and internationally. Headquartered in Wilmington, North Carolina, ESS has been a leader in international Air Quality projects, mobilizing globally toHungary, the Dominican Republic, Haiti, and Hong Kong, the Philippines and Vietnam.Should you have needs or requirements, both domestic and internationally, give ESS a call today: 910-799-1055.

Subpart IIII

In a previous blog entry regarding the ZZZZ and JJJJ RICE Rules , we discussed the National Emissions Standards for Hazardous Air Pollutants for Reciprocating Internal Combustions Engines (RICE NESHAP), and the New Source Performance Standards (NSPS) for Spark Ignition RICE Units, more commonly referred to as Subparts ZZZZ and JJJJ, respectively. There is another related rule that bears consideration, and that is Subpart IIII, the NSPS for Compression Ignition Internal Combustion Units (CI ICE).

There are two basic types of Stationary Reciprocating engines: spark ignition and compression ignition. Spark ignition engines use a spark, across a spark plug, to ignite a compressed fuel-air mixture. Typically, fuels for these engines are gasoline and natural gas. Compression ignition engines compress air to a high pressure, heating the air to the ignition temperature of the fuel, which is then injected. The high compression ratio used for compression ignition engines results in a higher efficiency than is possible with spark ignition engines. Diesel fuel oil is normally used in compression ignition engines, although there are dual-fueled varieties, where natural gas is compressed with the combustion air, and diesel oil is injected at the top of the compression stroke to initiate combustion.

The requirements of the Subpart IIII standards, particularly as they are related to performance testing, are dependent on the size of the engine, the manufacture date, the cylinder displacement, and whether it is used for emergency or non-emergency purposes. The EPA defines an emergency engine as one that is used for the purpose of maintenance checks and readiness testing, and is operated less than 100 hours per year. The owner of the emergency engine can NOT connect the engine to the grid under financial incentive and maintain the unit status as an emergency engine. Therefore, a peak shaving engine will not be classified as an emergency unit under the definitions of the Subparts.

For engines that are required to comply with Subpart IIII, including those engines located at Area Sources and engines less than or equal to 500hp located at Major Sources, there are no further requirements under the RICE NESHAP (Subpart ZZZZ). A Major Source is one that has the potential to emit 10 tons per year of any individual Hazardous Air Pollutant (HAP), or 25 tons per year of all HAPs. An Area Source is any source that is not considered a Major Source under this definition.

Regarding stack testing, an owner or operator of a CI ICE non-emergency unit built after 2007 with a displacement of >30L must demonstrate compliance by a performance test (stack test) for emissions of Particulate Matter (PM) and Oxides of Nitrogen (NOx). There are two methods for demonstrating compliance with either pollutant. The first is to show a percent reduction in emissions, and requires sampling for that pollutant at both the inlet and outlet to the control device for the source. Per IIII requirements, NOx must be reduced by 90% and PM by 60%. The second option is to limit the mass emission rate in the exhaust and only requires sampling at the outlet of the unit. The emission limit for NOx is 1.6 g/KW-hr (1.2 g/HP-hr). The emission limit for PM is 0.15g/KW-hr (0.11 g/HP-hr). In addition to the initial compliance performance test, owners of such engines must then perform annual performance tests to prove continued compliance with the standards.

The NESHAP and NSPS rulings can be an impenetrable maze without expert assistance, and the performance testing requirements can have a substantial impact on a facility’s operating budget. It is important to have a partner that is reliable and knowledgeable when approaching the many new emissions requirements being promulgated by the EPA and state governments. For assistance with your compliance needs, and performance testing requirements, ESS is available to help. If you believe you will or may have compliance issues under Subpart IIII, ZZZZ, or JJJJ, give us a call or an email today: 910-799-1055

ESS Announces Successful Completion of Industrial Air Testing Project in the Dominican Republic

The successful completion of an international stack testing project in the Dominican Republic by Environmental Source Samplers, Inc. (ESS) has led directly to a new air testing contract for ESS  in Port Au Prince, Haiti.  The project in Haiti was awarded and mobilized within a four day timeframe.


Wilmington, N.C., September 2012 — Environmental Source Samplers, Inc. (ESS), an established leader in emissions testing both domestic and internationally, today announced a successful conclusion to an air-testing project at a power facility in San Pedro de Macoris, Dominican Republic.

The power company is a client that ESS has performed stack testing services for in prior years, the last project completed in December of 2006. ESS has multiple clients in the Dominican Republic, and often performs work in the Caribbean, on average at least once a year. ESS mobilized a three-man crew from September 5th through 12th, 2012.

The project purpose was in-house engineering analysis for quality control and quality assurance, and to demonstrate compliance with emissions requirements as stipulated by the International Development Bank (IDB). ESS utilized USEPA 40 CFR Part 60 methodologies for all sampling requirements at the facility in San Pedro.

In addition to the successful completion of this project, ESS realized benefits in networking that will be invaluable in future endeavors into the Dominican and its neighboring country. Several contacts made during the course of the project have already led to further planned projects, and ESS personnel will be mobilizing to another power facility to perform sampling in Port Au Prince, Haiti, in the following week. The Haiti mobilization presents the challenge of a severely truncated lead and planning time. ESS was initially contacted regarding the project on Thursday, September 21st, awarded the work on Friday, September 22nd, and is planning to mobilize no later than Monday, September 24th.

Such needs for quick response and flexibility in operations are frequently the case in air-testing projects both domestic and international. Changes in project scope and requirements, late additions to air-testing needs and late changes in schedule are a common occurrence, but without preparation and experience these common occurrences can become extreme difficulties when mobilizing internationally. ESS has the competitive advantage of experience, drawn from international projects conducted in such locations as Hong Kong, the Dominican Republic, Hungary, and other points in Europe. The ESS network of reputable vendors and service providers help drive projects to completion within the required timeline and budget.

Founded in 1979, ESS has been performing industrial air quality testing since that time, and has developed into a leader within the field. ESS utilizes modern, consistently maintained equipment to conduct its stack testing services throughout the U.S. and abroad. They are qualified to conduct a wide range of EPA test methodologies among various air emissions sources and industries. ESS clients have easy access to the reliable and accurate reporting of stack test results through a secure online client portal.

Several million stationary reciprocating engines are in use throughout the United States. These engines, in general industry use, provide shaft power to drive process equipment, compressors, pumps, standby generator sets and other machinery. The uses are similar in agriculture, with many engines serving the purpose of driving irrigation pumps. Reciprocating engines also find wide application in municipal water supply, wastewater treatment, and in commercial and institutional emergency power and load-managing stations.

The Subpart ZZZZ RICE rule (see: A Guide to the ZZZZ and JJJJ RICE Rules) includes requirements to regulate emissions from new and reconstructed RICE units located at major sources and area sources of Hazardous Air Pollutants (HAP). A HAP major source is a facility with a potential to emit 10 tons per year of a single HAP, or 25 tons per year of a combination of HAPs. An area source is any source that is not a HAP major source. All RICE units >100 hp (at area sources) and >500 hp (at major sources) have Carbon Monoxide emission testing requirements.

If you have any questions concerning your operations and applicability under these rulings, don’t hesitate to contact our office today. Compliance with the rule must be achieved by May 3, 2013!

ESS Announces Successful Conclusion to Hungary Emissions Testing Project

Environmental Source Samplers, Inc.Environmental Source Samplers, Inc, (ESS), a leader in emissions testing worldwide, announces the completion of an air testing project at an Ethanol Plant in Hungary.  ESS is making great strides with their experience and expertise in international stack testing.

Wilmington, N.C., June 2012 — Environmental Source Samplers, Inc., an established leader in emissions testing both domestic and internationally, today announced a successful conclusion to an air-testing project at an Ethanol Plant in Dunafoldvar, Hungary.

The Hungarian based client contacted ESS after discovering an ESS blog post, International Stack Testing – Challenges and Solutions, in which ESS staff discussed some of the special circumstances and potential challenges that are encountered while conducting stack testing outside of the domestic USA.

The project was for the purpose of verifying vendor guarantees for a newly-installed boiler system and scrubber control device, for a regimen of pollutants that included Particulate Matter and Gaseous Emissions. ESS also provided multiple days of on-site monitoring with real-time results for engineering purposes as the Facility staff made adjustments for process optimization and tuning. ESS utilized USEPA and ISO methodologies; EPA and MCERT approved analyzers (European Union approved for emissions measurements in Europe); and provided the Facility a number of protocol blend gas bottles for the sampling project.

As is frequently the case in air-testing projects both domestic and international, the project required flexibility in operations. Changes in project scope and requirements, late additions to air-testing needs and late changes in schedule are a common occurrence, but without preparation and experience these common occurrences can become extreme difficulties when mobilizing internationally. ESS utilized its experience, drawn from international projects conducted in such places as Hong Kong, Dominican Republic and other points in Europe. The ESS network of reputable vendors and service providers helped drive this project to completion within the required timeline and budget.

Founded in 1979, ESS has been performing industrial air quality testing since that time, and has developed into a leader within the field. ESS utilizes modern, consistently maintained equipment to conduct its stack testing services throughout the U.S. and abroad. They are qualified to conduct a wide range of EPA test methodologies among various air emissions sources and industries.
