Clean Power Plan Repealed and Replaced

The Trump administration Wednesday finalized a rule to repeal and replace a capstone Obama-era carbon pollution regulation that they argue exceeded the Environmental Protection Agency’s (EPA) authority.

The new replacement rule to the Clean Power Plan (CPP), deemed the Affordable Clean Energy (ACE) rule, aims to give states more time and authority to decide how to implement the best new technology to ease net emissions from coal-fired plants.

“Under the CPP, the EPA Obama administration went beyond implementing best technology,” said a senior EPA official on a call with reporters Wednesday. “Under the CPP the Obama administration actually imposed emissions reductions on each and every state. We don’t believe that’s an EPA role or authority under the [Clean Air Act.]”

The result of the relaxed rule, the official said, could mean individual coal plants might increase their overall emissions. But, the official said, across the board the agency expects emissions to drop.

Preparing for Your Upcoming Stack Test

Source Emissions testing, or stack testing, is mandated by the Clean Air Act of the U.S. Environmental Protection Agency (EPA), which sets forth guidelines and requirements that must be met to determine a facility’s compliance with emission limits.  Any and all plants, factories, and facilities that utilize a stack as part of manufacturing or production operations are required to undergo stack testing in order to demonstrate compliance with current EPA standards.  There is more to stack testing than simple compliance, however.  A properly-executed testing plan gives you the diagnostic tools to help optimize your operations and improve energy efficiency — quality incentives for voluntary stack testing that is not simply driven by EPA requirements.  With careful preparation for stack-testing compliance and the proper execution of the test plan, a company can save money, protect workers, and effectively streamline their operations.

As a company prepares their facility for an upcoming stack test, reviewing the state-approved test plan is the best way to ensure that you understand all of the testing requirements.  Doing so is your greatest insurance that the stack testing results will show proper compliance with all relevant EPA air emission standards.  However, in many cases technical or legal jargon may make a portion or the entirety of the test plan difficult to understand, and it may not contain all of the required information necessary to conduct a successful test.  To assist you with this, we have put together the following Stack Testing Preparation Checklist to help you make sure that your company is properly prepared for your upcoming testing.  All items on this checklist should be reviewed with your qualified stack-testing team.

  1. What Load you will test at – This information is typically in your air permit, and/or determined by applicable federal/state  regulations.
  2. What Fuel you will burn – Different fuel types can have vastly different emission limits
  3. OSHA compliant platforms – How will the stack test team reach the sampling plane?
  4. Power Requirements – Do you have enough circuits?
  5. Safety/Insurance Concerns- What are your facility requirements?  Does your stack test company meet these requirements?
  6. Are your Test Ports free from blockage and EPA Method 1 Compliant?
  7. What Process Data are you required to document, and how will that data be logged?

Here at Environmental Source Samplers Inc., we’re familiar with the pitfalls a company can experience when faced with an upcoming test.  Advance preparation, with these guidelines in mind, will provide your company the ability to address any issues or questions prior to the stack testing date. Saving your company the time, hassle, and money that late revisions and changes inevitably cause.  These guidelines are also helpful in maintaining high levels of safety and compliance regardless of having a scheduled stack test or not, benefitting the overall operations and their environmental impact.

Choosing a stack testing company that has the appropriate background and experience for your industry will help ensure that your stack test will be successful.  The stack testing company should have the capability to execute the testing types and methodologies that govern your specific operations, while using equipment that is well-maintained and up-to-date.  Just as importantly, they should be current and informed on the changes and revisions to existing testing methodologies, since the EPA air emission limits and standards are subject to change as the Agency sees fit.

Stack testing is required and performed for the health and safety of the plant, the workers, and the environment.   It is also a diagnostic tool that provides insight into the efficiency of your operations.  However, whether you are testing for compliance or diagnostic purposes, careful preparation is the key to ensuring that your stack testing project gives you the data that you can use effectively.

EPA to Propose Repealing Clean Power Plan

WASHINGTON (Reuters) – The U.S. Environmental Protection Agency will propose repealing the Clean Power Plan – the Obama administration’s centerpiece regulation to fight climate change – and plans to solicit input on a rule to replace it, according to an EPA document seen by Reuters.

The decision marks the agency’s first formal step to sweep away the rule intended to cut carbon emissions from power plants, after President Donald Trump signed an executive order in March launching the EPA’s review.

The Republican president has expressed doubts about the science of climate change and has blamed former Democratic President Barack Obama’s efforts to cut carbon emissions for hurting the coal mining and oil drilling industries.

The Clean Power Plan, or CPP, was challenged in court by 27 states after Obama’s administration launched it in 2015. It is currently suspended by the D.C. Circuit Court of Appeals, which set a deadline of Friday for a status report from the EPA on how it plans to proceed.

Three Decades of Condensable Particulate Matter (CPM) Regulation

2017-03-17 Three Decades of CPM Regulation

WHAT IS CONDENSABLE PARTICULATE MATTER?

Condensable Particulate Matter (CPM) is material that is in a vapor state at stack conditions, but condenses and/or reacts upon cooling and dilution in the ambient air to become solid or liquid Particulate Matter (PM) immediately after discharging from the stack.  All CPM is assumed to be in the PM2.5 size fraction.

HOW DID EPA CPM REGULATIONS DEVELOP?

1987  After promulgating the PM10 National Ambient Air Quality Standards (NAAQS) the EPA began recommending that, in certain circumstances, states consider including the condensable portion of PM10 emissions in the determination of total and fine PM emissions from major stationary sources.

1991  EPA Promulgated Method 202.  The original Method used wet impingers – in which sulfur dioxide was captured and formed sulfur trioxide and sulfuric acid artifacts. This caused captures to be biased high by improperly quantifying the sulfuric artifacts as condensable PM.

Scientists Find Way to Convert CO2 Into Ethanol

CO2 to Ethanol

Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change. Their findings were published in the journal ChemistrySelect.

Researcher had hoped to convert carbon dioxide that had been dissolved in water to methanol, a chemical released naturally by volcanic gases and microbes, which can cause blindness in humans if ingested.

But instead of methanol, they discovered they had ethanol, a primary component of gin and also a potential fuel source. Surprised, the team realized that not only was their new material converting the carbon dioxide to ethanol, it needed very little outside support.

The material is a small chip–about a square centimeter in size–covered in spikes, each just a few atoms across. Each spike is constructed out of nitrogen with a carbon sheath and a small sphere of copper embedded in each tip. The chip is dipped into water and carbon dioxide is bubbled in. The copper acts as a small lightning rod, attracting electricity and driving the first steps of the conversion of the carbon dioxide and water into ethanol, before the molecules move to the carbon sheath to finish the process.

Preparing Your Hot Mix Asphalt Plant for Air Permit Compliance Testing

The saying “Time flies” never seems more appropriate than when air permits need to be renewed for Hot Mix Asphalt (HMA) plants.

If your plant’s permit is expiring soon (or even if it’s a bit down the road), it may benefit you to review the EPA-mandated testing required under your state-issued air permit.  With this in mind, allow us to provide a brief overview about air emissions testing for Hot Mix Asphalt plants.

Why are Hot Mix Asphalt plants required to test air emissions?

In the past, HMA plants were notorious for generating noticeable levels of dust, smoke, odors, and noise.   In 1973, the EPA enacted New Source Performance Standards (NSPS), which required HMA producers to pass strict emission standards and install control systems to prevent the release of dust and smoke into the air. A facility must also meet stringent visible emissions tests in order to comply with regulations.  These NSPS rules have had a dramatic effect on the decreased levels of pollution emitted by HMA plants, and thus the testing continues to be a part of the regulations with which HMA plants must comply.

When do Hot Mix Asphalt plants need to test for air emissions?

The date by which an HMA plant must conduct compliance testing and submit a report to the state EPA office is outlined in each plant’s individual air permit.  In some cases, the air emissions test report may be due 12 months or more before the current permit expires.

It is important to note that new HMA plants are required to conduct performance testing within 60 days after achieving maximum production rate, but no later than 180 days after initial startup of the facility. (See 40 CFR 60 Subpart A §60.8)

Nearly all HMA plants operate on a limited calendar, with summer being the busiest season.  As a result, there are a limited number of days available to perform emissions testing.  It is best to plan testing so that it occurs earlier than the permit requires in case the weather causes a delay or cancellation of the intended testing.

How far in advance must Hot Mix Asphalt plants provide notice of testing to the state authorities?

NSPS rule 40 CFR 60 Subpart A §60.8 specifically requires owners to notify the state regulatory agency 30 days in advance of the anticipated test date.

The state authority may also require submission of protocols in advance of testing.  Check your individual air permit for your state’s test protocol submission rules.

What tests are required under NSPS 40 CFR 60 Subpart I – Standards of Performance for Hot Mix Asphalt Facilities?

 According to 40 CFR 60 Subpart I, the following EPA Methods are required for air compliance testing at Hot Mix Asphalt plants:

  • EPA Method 5 – Measures Filterable Particulate Matter (FPM)
  • EPA Method 9 – Measures Visible Emissions (VE)

Some states require additional particulate testing via EPA Method 202, although the NSPS does not require it.  Please check with your state regulatory agency for the requirements concerning your facility.

When are air emissions test reports due to the state regulatory office?

It depends.  For instance, South Carolina requires a hard copy in office (not just postmarked) by the 30th calendar day post-test, but North Carolina allows 60 days to submit the report.

However, we recommend that you consult your air permit for a specific answer.  Your state-issued air permit will outline all the specifics for your emissions compliance requirements.

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.

ESS Conducts H2 Gas Test at Coca-Cola Factory in Hanoi, Vietnam

Environmental Source Samplers, Inc.October, 2013 – Hanoi, Vietnam – Environmental Source Samplers, Inc. (ESS) continues growth in the Asian market with recent air emissions and ambient test programs for clients in Vietnam where ESS has a established an office. ESS most recently secured a contract to sample for hydrogen gas at the Coca-Cola factory in Hanoi.

The project was conducted in October 2013 and led by ESS President Mark Looney, QSTI. ESS sampled for H2 gas at multiple electric forklift charging stations and surrounding areas.

When lead acid batteries are being recharged they generate hydrogen gas that is explosive. During all lead acid battery charging processes H2 is produced. If certain charging equipment and/or batteries are not functioning properly, cells are damaged, or ventilation systems are inadequate, H2 generation can be significantly greater than the lower explosive limit (LEL).

Coca Cola Factory, VietnamDepending on the metal alloy composition in lead-acid batteries, a battery being charged can generate two highly-toxic byproducts in addition to H2. One is arsine (arsenic hydride, AsH3) and the other is stibine (antimony hydride, SbH3). Generally, the air levels of these metal hydrides tend to remain well below the current occupational exposure limits during battery charging operations. However, their possible presence re-enforces the need for adequate ventilation systems.

Many industrial plants in Vietnam utilize electric forklifts and other equipment powered by these types of batteries. ESS can refine the Facility Health and Safety Plan, develop a sampling/test protocol for industrial hygiene targets, and then execute the project to conduct all the required testing.

ESS maintains its competitive advantage by continuing to build on international experiences, developing offices in strategic markets and assuring client satisfaction on every project.
