With climate change becoming a center of attention globally, much focus has pointed toward carbon capture and storage (CCS) in recent years. While USEPA has published general guidance for Class VI permitting, it is still a new permitting challenge for both scientists and regulators alike. Drawing on lessons learned from more familiar and well-developed regulatory frameworks will be beneficial.
In our Technical Bulletin, Applying Lessons Learned From Municipal Solid Waste and Coal Combustion Residuals to the Development of Testing and Monitoring Plans for CO2 Storage Projects, we focus on the testing and monitoring aspect of Class VI permitting and related complexities, including the project’s overall scale, enhanced costs, and enhanced regulatory risk. We discuss the key considerations for developing an effective CCS Testing and Monitoring Plan based on lessons learned from developed MSW and CCR monitoring programs, as well as how early planning and good judgment can help navigate the complexities associated with CCS projects and ultimately reduce those complexities and associated project costs.
Recommendations include meticulous site characterization efforts early in the CO2 storage project and tailoring the monitoring network. The latter includes placing monitoring wells based on multiphase modeling predictions, designing geochemically and geomechanically compatible monitoring wells, and using strategic statistical techniques to analyze and interpret monitoring data.
It is important to remember that for CO2 storage, groundwater monitoring is not intended to be the primary monitoring method for detecting fluid leakage and migration. It is only one of many required testing and monitoring methods. Even so, the monitoring network must be planned and established appropriately and then tightly coordinated with the other testing and monitoring methods to maximize the protection of underground sources of drinking water.
SCS Engineers will continue to post timely information, resources, and presentations to keep you well informed. These include additional guidance, industry reaction, and webinars with our teams using our website, on SCS Engineers LinkedIn, and on SCS YouTube on-demand forums.

Meet SCS Engineers’ carbon sequestration and deep well injection experts at BOOTH 729 at the 39th annual International Fuel Ethanol Workshop (FEW) & Expo, June 12-14, in Omaha, Nebraska.
The FEW provides cutting-edge content and unparalleled networking opportunities to the global ethanol industry within a dynamic business-to-business environment. It is the largest, longest running ethanol conference in the world—and is powered by Ethanol Producer Magazine.
The FEW delivers timely presentations with a strong focus on commercial-scale ethanol production – from quality control and yield maximization to regulatory compliance and fiscal management. The FEW is also the ethanol industry’s premier forum for unveiling new technologies and research findings. The program extensively covers cellulosic ethanol while remaining committed to optimizing existing grain ethanol operations.
Abstract: Carbon Capture and Storage (CCS) is becoming increasingly attractive due to growing climate change concerns as well as tax incentives related to conducting CO2 capture. Facilities that capture CO2 may consider storing captured CO2 via geologic sequestration (GS). GS at a given location requires a Class VI Underground Injection Control (UIC) permit for a Class VI UIC well(s) to inject supercritical CO2. These permits require multiphase flow modeling to delineate both the extent of the supercritical CO2 plume and areas that exceed a critical pressure threshold as a result of injection. We have found numerical modeling is also valuable during project scoping to provide a sense of what the total CO2 storage capacity may be for a given project. To determine long-term storage capacity, CO2 trapping (storage) mechanisms must be considered, including structural/stratigraphic, capillary, solution, and mineral trapping (depending on geochemistry). Solubility trapping appears to be the ultimate trapping mechanism for injected CO2 under most geochemical conditions; therefore, solution storage efficiency will be a key metric for project scoping. Solubility trapping occurs when the CO2 dissolves from its separate, buoyant phase into formation pore water. If the total available pore space for the project and the solubility limit of CO2 can be estimated, then the total solution storage capacity can also be estimated. Then numerical modeling can be used to estimate design and operational parameters to quickly examine under what conditions the most efficient use of pore space occurs. In this example, we investigated what factors may promote solution storage efficiency using a multiphase flow model. This includes how supercritical CO2 injection rate, duration, and location(s) affect solution storage efficiency. This simplified study concluded that injection rate, duration, and location(s) all affect solution storage efficiency. Project-specific considerations need to be incorporated into the model in order to determine the conditions ideal for maximizing solution storage efficiency.
The 2023 FEW program has four concurrent tracks and three additional events:
The FEW typically draws industry professionals from all 50 states and more than 30 countries. Upwards of 550 biofuels producers from 209 facilities all over the world attend each year.

Glenn Haave has had a close relationship with protecting our environment for years, ever since his days working on the ocean towing ships in and out of ports. He figured his deep appreciation of his natural surroundings and desire to protect them might carry into his chosen career path, especially after earning a Bachelor of Science in Geology. But when he came to SCS Engineers as a high-spirited, new graduate, he had no idea of the opportunities that would come his way— both at SCS and serving in the U.S. Coast Guard Reserves.
“Both SCS and the Coast Guard hold you accountable to rise to the occasion and get the job done. With that trust and delegation of responsibilities, I am challenged to become a leader, which gives me a sense of duty and confidence,” Haave says.
Combining Geology, Hands-On Experience, and Teamwork
Starting at SCS doing groundwater and soil sampling and helping remediate landfills for redevelopment, Haave proved to be a fast learner. Quickly building on his skills, he was presented with a unique proposition– to join one of only a few multidisciplinary teams in the country that design and install deep well injection infrastructure. EPA-approved injection wells are safe for placing fluids underground into porous geologic formations. These underground formations may range from deep sandstone or limestone to a shallow soil layer. Injected fluids may include water, wastewater, brine (salt water), or water mixed with chemicals.
Planning, permitting, and executing these projects is a multifaceted undertaking encompassing geologic consulting, reservoir engineering, and deep drilling, with environmental protections and sustainability as core goals.
“Few geologists ever get to work on this type of job. These projects require a lot of capital, time, and very specialized expertise. I was fortunate to be working at SCS’s Miami office at the right time, able, and willing,” says Haave, drawn to complex tasks calling for a razor-sharp eye for detail, focus, and discipline.
Drawing on his experience supporting the Miami-Dade Water and Sewer Department Ocean Outfall Legislation Injection Well Program, where he saw 11 wells constructed in a demanding, high-profile project, he is now on a multidisciplinary team of SCS professionals.
Innovations in Carbon Sequestration – Protecting Our Environment
Now, he takes on a new charge: working on a type of deep injection well called a Class VI well. This sophisticated infrastructure directs carbon dioxide (CO2) liquids and gases into the ground for long-term storage. A fairly new, EPA-approved carbon sequestration technique, it is proven effective at substantially reducing CO2 emissions to the atmosphere.
“Class VI wells are an exciting evolution as the world looks to decarbonize the economy. I feel like I am part of an extraordinarily innovative solution where I am using my background to support a global effort to impact our climate positively,” Haave says.
“I feel a sense of purpose in that we are helping mitigate exponential global warming. At least as important, I am comforted that what we do brings hope that my son, daughter, and their generation will grow up on a healthy, safe planet.”
Another Dimension – U.S. Coast Guard A School
As he embraces this unique opportunity to help the environment, he celebrates another milestone: graduating from U.S. Coast Guard A School and advancing in rank to Marine Science Technician Petty Officer Third Class. His calling will be responding to pollution incidents to protect U.S. waters and inspecting facilities and container vessels that transfer hazardous materials to and from land.
Getting into the Reserves is not easy, nor are the next steps. Making it into A school after boot camp is typically a two-year journey: the waiting list of accomplished graduates is long.
Haave finished three intensive months of classroom work; mock training in the field, morale-building exercises to keep spirits high while away from family and friends, and a battery of testing.
Through these rigorous trials, he took on the honorary role of Master at Arms, leading and mentoring his shipmates and serving as a liaison between the crew and captain.
“Becoming a Coast Guardsman was like a dream come true. It was something I had wanted to do since I was 19. But I needed time to mature. I did a lot of soul searching before I could fully realize what was entailed in living up to Coast Guard expectations; to truly embrace that it’s about a sense of duty to country and family, and to deliver on that conviction,” says Haave, now 37, and nominated as a most inspirational person by his shipmates and instructors.
When he shared his long-envisioned, materialized aspiration with his SCS supervisors, he was unsure what they would think; he was taking on another big commitment.
“They were not only accommodating, but they are proud. SCS Engineers is a military-friendly organization. They are always supportive, flexible, and believe in me.”
In the Coast Guard, he had a choice from a far-encompassing list of specialty areas, given his high military school entrance score. He chose marine science technology because it tied in with his civilian work – navigating and ensuring adherence to federal regulations and being a steward of the environment.
Looking Forward
Gazing back at how far he’s advanced in just the last few years, then looking forward, Haave says, “You know, I’m just 37 years old. I feel like I have a lot more in my gas tank –the amazing experiences I have been fortunate to have are just the beginning. I see more opportunities to advance as a leader and to become an even more rounded geologist, able to approach every project comprehensively and deeply.”
We thank all of our veterans and appreciate Glenn Haave for his service to the U.S. Coast Guard and his commitment to protecting our environment with SCS Engineers by advancing sustainable environmental practices and solutions.

Safe engineering takes discipline and teamwork –qualities that have always served SCS and our clients with innovative, proven solutions for running operations more efficiently and greener. For a rewarding career, consider SCS Engineers, where all employee-owners have a vested interest in every solution.
Kacey Garber wanted to be a storm chaser when she grew up, trained to detect and alert others of brewing severe weather. But then she found geology and went on to earn graduate and postgraduate degrees in this discipline, which brought the summa cum laude scholar to SCS Engineers. Her charge is groundwater protection, an area where she aspires to grow her expertise further.
The young professional (YP) is already moving quickly along that trajectory, beginning by supporting landfills and utilities and now applying her strong skill set in a highly specialized, fast-evolving arena – deep-well injection.
A common thread binds Garber’s main interests – groundwater protection, geology, and meteorology/trained weather spotter, which she still does in her spare time.
“What draws me to these niches is the thrill of being part of the scientific community collecting and interpreting compelling data to figure out solutions. And not just any solutions but those with the promise of helping protect people and the environment. That’s where I want to have an impact,” she says.
She’s heard of climate change almost her whole life and has thought for almost as long that someday she would play some problem-solving role to help mitigate its effects.
Garber splits her time at SCS between several areas. She monitors and tests groundwater for landfills, closely following both active and closed sites, and helping landfills prepare for post-closure. She supports electric utilities with groundwater issues potentially related to their closed coal ash ponds and disposal sites. And now, she is leading groundwater protection tasks for class VI deep-well injection projects as part of a dedicated team that permits and builds these wells.
The cutting-edge, EPA-regulated technology injects and stores carbon dioxide underground safely, preventing this potent greenhouse gas from releasing into the atmosphere.
Garber’s on-the-job experience in the field is paramount to her new, added role. Her studies in geology focused on sedimentary basins are also proving important.
“Sedimentary basins [where large bodies of rock occur] are ideal spots for carbon sequestration. But first, you must understand the geologic characteristics of the basin and each rock formation and determine exactly which locations within the basin are best for injecting and storing carbon dioxide. That’s a big part of what I do to ensure efficiency and safety,” she says.
In her eyes, Garber lives and works in the best of two worlds in that she can concentrate on different but related interests.
“Joining our deep-well injection team brings me back to my roots in traditional geology. But it also enables me to stay on the groundwater monitoring track, which is meaningful as I aim to position myself as a national expert who can do this important work. Ensuring water quality is critical to protecting the environment and communities, as a large part of our country relies on groundwater for its water supply.”
As she grows her reach into deep-well injection, she grows her relationships too. The multidisciplinary team—all new colleagues to her a year ago are her newest work family addition.
“It’s humbling to partner with so many incredibly smart people, each with their respective areas of expertise. We’ve come to trust each other’s judgment as we solve issues together. And as it turns out, we have a lot in common, especially our love of nature—the joy we find in being outdoors, camping, and hiking.”
Getting a foot in the door of a nationwide environmental firm has been good. Especially one that welcomes YPs and is vested in their career development, something she found uncommon among companies with as great a geographical reach and breadth of expertise.
She seized the opportunity.
“I saw it as a way to gain visibility early in my career. And to become well-rounded in my discipline. We perform groundwater monitoring for many project types, and there are parallels in how it’s done in each; I can support and learn from all of them.”
At the same time, she explores other specialized areas.
“There are designated experts here at SCS in many professions and industries dedicated to caring for the environment. They are great resources to learn from.”
Where she would land one day was unknown for a while. Garber thought she’d become a professor or researcher at one time. But that changed when she interned with the United States Geological Survey, venturing beyond the classroom and lab to assess land use impacts on water quality and floodplains.
“I liked solving problems out in the field and decided pretty quickly that’s where I wanted to be,” she says.
The desire to teach is still in her, though. She travels state to state, presenting to regulators, technology experts, and other seasoned professionals and decision-makers on groundwater modeling, monitoring, and testing.
She also reaches out to ambitious geology students, visiting them on campus to tell them about deep-well injection and carbon sequestration and that the company she works for does these projects around the country. Their curriculum rarely includes an introduction to this specialized niche.
Remembering herself as one of them, Garber says, “I didn’t know of this work in college. I first learned as a newcomer to SCS.
It intrigued me, and I was excited to hear that the deep-well injection group needed a team member with a strong monitoring background. Later I thought, how cool it would be for students to discover this potential career path early.”
How else does she fill her days? Besides watching for and reporting developing storms to weather bureaus– she called in a funnel cloud once out in the field—she plays guitar in a local band.
Sometimes she goes solo and has played and sung at a nearby rehabilitation center and nursing home.
“I love playing music. It makes me happy. But what really feels good is to play for folks, especially those who may be more limited in what they can do and where they can go. For them, listening to music and dancing seems to be the highlight of their day. It makes me happy to see them happy.”
Ensuring a safe, healthy environment and a better world for everyone is about a commitment to people, community, and hard work. Thank you, Kacey Garber, for your dedication to keeping our groundwater safe, for helping execute innovative solutions to advance sustainability, and for bringing a lift to others along the way.

Did you miss the 2022 Annual GWPC & UIC Conference in Salt Lake City? We welcome you to view SCS Engineers’ presentation by Kacey Garber entitled “Sensitivity of Aquifer Chemistry to Changes in Carbon Dioxide Partial Pressure: Implications for Design of Groundwater Monitoring Protocols,” where Kacey discusses permitting requirements for groundwater monitoring for carbon sequestration and storage sites.
In her technical presentation, Kacey Garber of SCS Engineers discusses the great care taken in the design and operation of the injection of carbon compounds to ensure that the sequestration is effective and permanent. Each injection site also has permitting requirements for groundwater monitoring in any overlying aquifer as a protective measure. Because the injection and sequestration periods are long, CSS solutions need a cost-effective groundwater monitoring program with a robust sensitivity to detect any leakage. By establishing a groundwater monitoring protocol specific to the site, sensitive to changes in the partial pressure of carbon dioxide, and relatively insensitive to natural variability and hydrochemical facies changes, implementing optimal and cost-effective groundwater protection is possible. Using a case study, Kacey tells us how her team did this in detail.
Kacey Garber is an experienced groundwater project manager for active and closed landfills, including routine groundwater monitoring and statistical analyses; reports and permit applications; designing sampling and analysis plans; special groundwater studies; and conducting groundwater well construction planning and design.
Landfill efficiency: every landfill owner or operator knows that landfills are distinctly unique. Consequently, landfill gas collection and control systems (GCCS) and leachate management systems with highly engineered components are configured precisely to tailor to each landfill’s needs. North American landfills have always tried to be good neighbors, but now are making greater strides toward reducing emissions and protecting groundwater with master planning and technology. These plans keep the effectiveness of these systems running as efficiently as possible and help prevent expensive and extensive repairs.
Today’s blog takes us out in the field examining how to plan for these flexible high-dollar infrastructure systems. These plans are taking landfill operations into the future and are adaptable to changing regulations around emissions and the evolving waste streams that affect gas production.
We’ll also provide resources to similar articles about leachate systems, remote monitoring systems, drones, and carbon sequestration that are helping to keep your carbon footprint even lower and support landfill efficiency.
In the April issue of WasteAdvantage Magazine, Professional Engineers Vidhya Viswanathan and Maura Dougherty discuss how operators with 5-year and master plans in place get a payoff with a system that serves them well and costs less. They can prepare early for capturing their gas, use the plan to install gas collection infrastructure on a timely basis, and help guide them through post-closure among the daily benefits.

“Sensitivity of Aquifer Chemistry to Changes in Carbon Dioxide Partial Pressure: Implications for Design of Groundwater Monitoring Protocols,” Kacey, Julie O’Leary, and Charles Hostetler are all with SCS Engineers. The team will discuss Carbon Sequestration and Storage (CSS) solutions. Great care is taken in the design and operation of the injection of carbon compounds to ensure that the sequestration is effective and permanent. Each injection site also has permitting requirements for groundwater monitoring in any overlying aquifer as a protective measure. Because the duration of the injection and sequestration periods are long, it is essential for CSS projects to have a cost-effective groundwater monitoring program with a robust sensitivity to detect any leakage.
In this case study, the SCS team has examined the sensitivity of aquifer chemistry (major and minor cations and anions) to the partial pressure of carbon dioxide using an aqueous speciation/solubility/sorption model. They examined a number of hydrochemical facies, both natural and synthetic, to determine which geochemical parameters are most likely to be affected by changes in the partial pressure of carbon dioxide. The team anticipates that the regulatory framework and practice for CSS will be similar to that of Municipal Solid Waste (MSW) and Coal Combustion Residue (CCR) disposal sites. Prior to the injection of carbon compounds, the overlying aquifer is characterized and background values for key parameters are established. During the injection and post-injection phases of the project, there is periodic monitoring of the groundwater parameters, which they anticipate will be compared to the established background. When Statistically-Significant Increases (SSIs) are found, an Alternate Source Demonstration (ASD) will have to be prepared that attributes the SSIs to the CSS operation or to some other source. By establishing a groundwater monitoring protocol that is specific to the site, sensitive to changes in the partial pressure of carbon dioxide, and relative insensitive to natural variability and hydrochemical facies changes, optimal and cost-effective groundwater protection can be implemented.

Thursday, June 23 at 10:30 – 12:00 Class I UIC
“Microbially Influenced Corrosion in Injection Wells: A Case Study in a Class I Well for Coal Combustion Residuals,” with Stephanie Hill. Stephanie will discuss microbially influenced corrosion (MIC) is known as a direct cause of mechanical integrity failure in injection wells. While premature failures of expendable components, such as casing and packers, are inconvenient and expensive, this is not the only reason to proactively address downhole biological issues. Stringent control and mitigation of biological activity are imperative to minimizing borehole fouling and subsequent plugging of an injection reservoir. If left untreated, a well’s long-term reservoir health and operational efficiency may be jeopardized.
This presentation will summarize a case study of MIC-related failure in a Class I injection well used for leachate disposal from a coal combustion residuals facility. The well failed to maintain internal mechanical integrity just six months after being commissioned. We’ll walk through the investigation process, which includes annular pressure testing, downhole caliper logging, casing thickness detection, injection fluid analysis, and metallurgical analysis to identify the cause of failure. Following the replacement of the injection casing and packer, injection tests were conducted to assess the potential impacts of MIC on the reservoir’s ability to accept injected fluids. A proactive disinfection plan was customized based on the unique investigative results and implemented to prevent future MIC-related issues.
Stephanie Hill is a hydrogeologist, program leader for SCS Engineers’ Carbon Sequestration and Deep Well Injection practice, and licensed Professional Geologist. She earned a BS in Geosciences at the University of Texas, emphasizing hydrogeology and geomorphology. Stephanie’s early career focused on environmental compliance for mineral and fossil fuel industries at the Texas Commission on Environmental Quality (1996 to 2000) and the Railroad Commission of Texas (2000 to 2012). Currently, she leads a team of geologists and engineers to advise SCS clients of various industries on geologic storage options for carbon neutrality and disposal solutions for liquid residuals.
California’s AB 32 legislation has proven to be one of the most successful legislation in the U.S. regarding statewide efforts to reduce GHG emissions. This has been started with the implementation of the early action measures stated in the Scoping Plan, which included early regulations to reduce GHG emissions in many different industry sectors, and then moved to the establishment of the MRP and C&T programs, which have created incentives for facilities to reduce their GHG emissions. The nine early action measures have been documented to reduce California’s GHG emissions with an estimated reduction of 13.16 percent from 1990 emissions in the year 201813. As a result of these programs’ implementations, California has met its goal to reach 1990 emissions levels by 2020 and had done so by 2016, four years before its proposed target year.
With the continued implementation of new programs at the state, local, and federal level, growing economic incentives to reduce emissions, and drive that led to the success of the emissions reduction goals of AB32, California is on a very promising path to achieving its latest goals to combat climate change.
