If you can solve their many challenges, landfills often are perfect sites for a myriad of uses. Landfill redevelopment can be smart growth, taking advantage of existing infrastructure and nearby populations to provide infill opportunities for commercial, industrial, residential, and recreational development, sometimes with an opportunity for alternative energy such as solar power. And more active use of a closed landfill site makes post-closure care more robust as compared with quarterly inspections.
Register for SCS Engineers’ February webinar to learn more about the environmental and regulatory strategies to assess and redevelop closed landfills for reuse and, by doing so, set realistic goals toward cost-effective and sustainable economic development.

EPA is releasing the interim guidance for public comment. The guidance provides information on technologies that may be feasible and appropriate for the destruction or disposal of PFAS and PFAS-containing materials. It also identifies needed and ongoing research and development activities related to destruction and disposal technologies, which may inform future guidance.
The interim guidance addresses PFAS and PFAS-containing materials including:
The agency is also providing guidance on testing and monitoring air, effluent, and soil for releases near potential destruction or disposal sites. EPA’s interim guidance captures the significant information gaps associated with PFAS testing and monitoring and identifies specific research needs.
The interim guidance is intended to assemble and consolidate information in a single document that generally describes thermal treatment, landfill, and underground injection technologies that may be effective in the destruction or disposal of PFAS and PFAS-containing materials.
As further research and development occur on this issue, EPA will incorporate this increased knowledge into future versions of this guidance to help decision-makers choose the most appropriate PFAS disposal options for their particular circumstances. EPA will review and revise the interim guidance, as appropriate, or at least once every 3 years.
See the EPA website: EPA Interim Guidance on Destruction and Disposal of PFAS.
Instructions: All submissions received must include Docket ID No EPA-HQ-OLEM-2020-0527 for this rulemaking. Comments received may be posted without change to the Federal eRulemaking Portal. You may send comments by any of the following methods:
According to Waste Dive, the document is the first such federal guidance on the destruction or disposal of PFAS or PFAS-containing materials. It describes the available science used in three major techniques: deep well injection, landfilling and thermal treatment. Acknowledging uncertainty about potential environmental effects, the EPA proposed the interim storage of PFAS-containing waste until further research can “reduce the uncertainties associated with other options.”
Industry groups such as the National Waste & Recycling Association (NWRA) and the Solid Waste Association of North America (SWANA) said they are analyzing the document and discussing with their members, such as SCS Engineers what the interim guidance means for daily landfill operations. The trade groups will submit comments on the document by the Feb. 22 deadline.

SCS periodically prepares Technical Bulletins to highlight items of interest to our clients and friends who have signed up to receive them. We also publish these on our website at https://www.scsengineers.com/publications/technical-bulletins/.
Our most recent Bulletin entitled EPA Seeks Feedback On Inactive Surface Impoundments at Inactive Electric Utilities summarizes the EPA’s request for comments and information pertaining to inactive impoundments at inactive facilities.
Operators and owners who may be affected by forthcoming decisions around inactive CCR surface impoundments include electric utilities and independent power producers who generate CCR within the North American Industry Classification System (NAICS) code 221112. Though the EPA states “other types of entities … could also be regulated” and advises those wanting to confirm if the regulation applies to them to read the applicability criteria and comment. Landowners with a legacy surface impoundment on their property purchased from a utility will want to review the proposed definitions closely.
SCS Engineers will continue to post timely information, resources, and presentations to keep you well informed. These include additional guidance, industry reaction, and webinars for our clients.

SCS Engineers announces Brittney Odom’s promotion to the Southeast region’s Environmental Services Director. Odom will continue expanding and integrating SCS’s environmental engineering and consulting operations to provide more streamlined and efficient services in her new role. She will lead environmental operations in Alabama, Florida, Mississippi, Georgia, and the Caribbean. As with all SCS leaders, she continues serving her clients in Boca Raton in her expanded role.
Odom supports real estate developers, municipalities, banks, and insurance firms to identify properties’ environmental conditions. Next, depending on soil, water, and geotechnical testing determines the appropriate environmental due diligence and the engineering activities necessary to redevelop them and be in 100% compliance with local and federal rules.
There is an active push to develop more affordable residential housing in the U.S. Real estate developers and residents want to be close to business and transportation hubs, but potential development sites could require remediation. Once agricultural sites, golf courses, or at one-time housing industrial operations, these properties need environmental testing, due diligence, possibly remediation, or vapor intrusion barriers to ensure the safe redevelopment. No matter the condition, properties with a past can return to pristine condition and make desirable residential and mixed housing locations, supporting economic development.
“It’s important to know and understand all of the options ahead of time to keep costs down and environmental quality up for sustainable communities,” stated Odem. “You need to reassure all parties that there is no leaking storage tank or anything that could compromise health.”
Her focus recently is on the redevelopment of large-size properties contaminated with arsenic and other legally applied pesticides. These property types include golf courses and agricultural land that have become inactive but are in high demand for residential use. These projects may need soil management, including remediation, soil blending, and placement restrictions.
Odom has years of experience conducting environmental site assessments, overseeing remediation activities, and submitting regulatory reports, including Phase I & II assessments in Florida, Tennessee, Louisiana, Texas, and the Caribbean. These focus on gas station properties and bulk storage terminals for large oil companies, often located on prime waterfront sites.
Additional highlights in Odom’s professional career include expertise in the applicable Florida Regulatory Chapters and Standard Operating Procedures. She also has experience in state and international cleanup efforts and their associated regulatory procedures. She participated in successful environmental closure efforts, with imposed engineering controls and property restrictions.
Odom has ten years of experience managing subsurface investigation and conducting oversight during remedial activities, including source removal and remediation system installation. She holds certifications in 40-Hour HAZWOPER/OSHA training, Loss Prevention System, CPR, RCRA Hazardous Waste, DOT Hazardous Waste, and American Petroleum Institute certification.
“Brittney’s breadth of experience solving the complexities of large scale redevelopment while meeting all environmental regulatory compliance enables her to innovative better solutions,” said Carlo Lebron, SCS vice president and director of SCS’s Southeast operations. “She’s an expert, with access to our deep bench of engineers, scientists, technology, and even economists within SCS.”
SCS Engineers now provides the Augusta Environmental Services Department with engineering, environmental and testing, and Construction Management & Quality Assurance Services at the Deans Bridge Road Landfill, in Blythe, Georgia. The facility operates under the State of Georgia Environmental Protection Division as a Subtitle D Landfill, accepting up to 1,500 tons per day of waste. Active and closed sections of the landfill comprise approximately 1,177 acres of property. Some additional acreage contains ancillary facilities such as office and maintenance buildings, customer drop off area, sediment ponds, roads, and leachate holding facilities. The Augusta Department of Environmental Services is responsible for the landfill facilities, solid waste management planning for Augusta, and all residential solid waste collections. Additionally, the Department is responsible for the Augusta Brownfield program and other environmental compliance issues.
Landfills are carefully engineered facilities closely regulated and monitored to ensure they have the protections necessary to prevent contamination of groundwater, air, and adjoining land. Best landfill management practices include collecting and treating leachate – the water that passes through a landfill. The methane gas naturally produced from decomposing landfill waste is collected and converted into various forms of energy – including compressed natural gas. This alternative fuel powers Augusta Solid Waste trucks or is a substitute for pipeline natural gas.
The Department consolidated all landfill services assigning them to SCS Engineers, a professional environmental consulting firm with over 50 years of experience in performing landfill site acceptability studies, landfill design services, landfill environmental compliance activities. The firm was already engaged in the Landfill’s Gas Collection and Control System (GCCS) expansion. The consolidation of services provides a more cost-effective approach for permitting, design, operations, monitoring, and maintenance. The comprehensive SCS team is a uniquely qualified and experienced full-service consulting and engineering team with demonstrated relevant field experience in Georgia. Leading the team is Sowmya Bulusu, a Georgia Professional Engineer, with over 12 years of landfill engineering performed in accordance with the Environmental Protection Division (EPD) of the Georgia Department of Natural Resources, the Georgia Solid waste management Act, and other applicable federal, state, and local rules and regulations. As the Project Director, Carlo Lebron is a registered Georgia Professional Engineer for 15 years bringing over 21 years of experience on over one hundred solid waste projects.
“The SCS team brought the five-year permit review submittal package in early, giving Georgia’s Environmental Protection Division plenty of time to deem it administratively complete,” stated Sowmya Bulusu. “Working with our field technicians, we quickly identified and brought at-risk gas wells into compliance, used our drones to provide an aerial survey of the entire landfill, saving Department funds.”

A two-part interview with Landfill & LFG Engineer Sol Sim, Product and SCS Field Services Manager Oliver Early, and Software Developer Brooks Ballentine.
As technology advances to optimize landfill operations and ensure compliance, so does the amount and type of data available to support operators in making informed decisions.
The industry is adding more and more data points to fill in the story of a landfill’s health, driving this demand for ‘big data,’ delivered in real-time. Sprouting alongside this big data trend is another one: employers rely less on laptops and more on mobile devices, and they expect those devices to have sophisticated functionality.
In response, SCS Engineers launched SCS MobileTools®. This powerful app is the latest addition to SCSeTools®, a platform created to standardize data acquisition, optimize data use, and ensure that data is secure.
Watching in Real-Time
MobileTools enables field workers to pull up data on their iOS or Android mobile devices and observe real-time activity through a secure, wireless connection. It means they no longer have to connect instruments to their laptops and forward files to another source for upload to the eTools platform.
Instead, data goes from users’ smart devices to the cloud, enabling field workers, as well as operators and other decision-makers who work remotely, to access that information immediately.
“MobileTools builds on SCSeTools, which constantly takes in data and validates, analyzes, displays, and reports on that data. We realized that by incorporating technologies we’ve already built into this platform into the mobile devices, existing data acquisition workflows could be enhanced,” says Brooks Ballentine, SCS director of Software Development. “The result reduces effort and costs while increasing accuracy.”
“We’ve added wireless data transfer to MobileTools because the ability to access information within 24 hours is not good enough. We want to be within minutes to catch exceedances immediately,” says SCS engineer Sol Sim, who manages clients’ landfill gas operations.
“This is a real-time upload. So, if technicians are out in the field collecting data and a well has an exceedance, they can send a notice. If corrective action is required, the tech is already there to take that action,” he says.
Keeping Tabs on Flares
MobileTools is equally instrumental in keeping close tabs on flare activity, capturing information to identify overall flow trends, and ensuring the system meets stringent compliance requirements.
“Each flare has a data logger that records regulated parameters, such as gas flow and temperature. Data is stored minute-by-minute on the logger and typically requires an extensive manual process or expensive and complicated networked solutions to aggregate data in a centralized data repository. With MobileTools, this same data is transmitted in a simple process using existing mobile devices,” says Oliver Early, the product manager of SCSeTools-DataServices.
Early’s story around SCSeTools began in 2008. At the time, he was a client of SCS, paying to use the app to support a landfill gas-to-energy developer in ensuring regulatory compliance.
“I joined SCS in 2013 to come up with more features and push the app forward with new ideas and new ways of doing things, with wireless data transmission being the most recent advance,” he says.
Users of MobileTools can interact with site-specific data such as exceedance metrics for landfill gas, liquid levels, and surface emissions. And they access touch-enabled data charting to review daily gas loads recorded by flares.
MobileTools has the ability to attach photos to provide supporting visuals for more information and or to put data in context. This facilitates communication between field technicians, site managers, and corporate management, who can get a more tangible “picture” of what’s going on in the field.
As with every feature in the eTools suite, MobileTools is designed with data integrity and security in mind.
In the case of landfill operations monitoring data currently collected by hand, MobileTools will digitize the process, allowing for faster acquisition and near real-time analysis.
Integrating More and Different Data – Validation
“We are integrating data in MobileTools that is not currently collected on standardized instruments, such as liquid levels and pump cycle counts.
“So, with monitoring data that was recorded on paper, then entered into spreadsheets, techs now type it directly into the device. It is validated and then uploaded,” Ballentine says.
These and other features and functions are designed to be time and money savers. Field workers who now have a streamlined protocol can accomplish more in a day, freeing themselves for maintenance projects and other tasks. Operators can rely less on consultants to review data and identify potential issues or needed improvements.
Sim is part of the team involved in further developing and testing SCSeTools. That landfill practitioners developed the platform for landfill practitioners is key to its effectiveness, he surmises.
“We are not a software company dabbling in landfills; we are landfill operators. We know the industry, as well as the functionality needed in landfill software.
“Field engineers, staff, and technicians have been asking for a mobile app for some time. The ability to have data at our fingertips in the field is a tremendous tool for quickly troubleshooting issues,” Sim says.
Part I of the Interview Series
A two-part interview with Landfill & LFG Engineer Sol Sim, Product and SCS Field Services Manager Oliver Early, and Software Developer Brooks Ballentine.
Back in the day, environmental engineers and landfill operators had to create their own spreadsheets to track mountains of data, then try and figure out what all that data meant, a tedious process with limited functionality. But that’s changing, and SCSeTools® is at the forefront of the evolution. This powerful yet user-friendly digital platform automates data management; harnesses an ever-growing volume, type, and complexity of information; and expands on what solid waste professionals can do with that information.
Created by landfill practitioners, for landfill practitioners, SCSeTools collects, monitors, analyzes, and manages data on key landfill operations and assists in reporting. It’s leveraged by SCS staff and its clients nationwide to help facilitate sound operational and engineering decisions while saving time, labor, and money. Because operators get information in near-real time, they can act quickly and proactively should red flags spring up in their tightly regulated world.
The platform includes three modules: SCS DataServices®; SCS Groundwater™; SCS Leachate™; and the newest feature—SCS MobileTools®. Collectively these customizable toolsets have the flexibility to capture the big picture of a site’s overall health or zero in on what’s happening at a single gas wellhead, leachate collection sump, or other location. The modules’ design supports the smallest and largest sites and serves operators managing one, 10, or even hundreds of facilities.
From the Big Picture to the Fine Details
SCS DataServices is the flagship product and the one that SCS engineer Sol Sim uses most. This module captures and utilizes landfill gas facility monitoring and management data. It’s also designed to serve as a compliance reporting tool.
Sim likes to tap into the app to look through different lenses, depending on what he needs to see and understand.
“You can use SCS DataServices to get a broad overview of what is happening, but you can also drill down to see where you need to focus to ensure you are spending time and resources efficiently,” he says.
Being able to dissect large volumes of data quickly, then key into the finer details as needed has made his job easier. And he can work smarter and faster.
“Without this tool, it’s a bit of a needle in a haystack. But now, we can easily visualize and pick out relevant, near real-time data to assess performance. And when there are deficiencies, we can make adjustments promptly—maybe upgrade a wellhead or upgrade laterals to optimize gas production,” he says.
Connecting the Dots in a Visual Format
The GIS mapping function, a component of DataServices, has been one of Sim’s go-to tools. It provides data points for individual locations within a landfill system and helps connect the dots in a visual format.
“You have point references and can spatially display a lot of data at once so, unlike with a spreadsheet format, you can see and process where a well is in relation to others,” he says.
Custom mapping captures any parameter, whether data points around gas flow, header vacuum or gas quality. Ranges are set to identify trends and, ultimately, provide information to make more informed decisions.
This ability to spot trends or patterns is integrated into features beyond mapping. A built-in algorithm helps determine if a client’s operations are trending in the right direction, and that determination can be made as patterns unfold, which helps field staff stay on top of the curve.
“If changes occur slowly, it typically takes time to notice, but if you look at six months or more of data at a time, you see that 1 percent change in temperature or flow, for example, that has crept up incrementally. You have one visual snapshot that captures a lot of data fast. So, if there are issues, you can get to the route quickly and make adjustments practically in real-time,” Sim says.
The DataServices module has served well as a troubleshooting tool. Sim illustrates with a real-life scenario: a client whose landfill gas-to-energy project was grossly underperforming.
“They had data but no way to review it efficiently to try and understand what was happening. They were ready to bring in a new operator. We were able to come in; upload their data into our system; identify the problem; and make easy, relatively inexpensive upgrades that increased their gas extraction by close to 15 percent.”
Besides helping to realize direct dollar benefits, the tool can compute and outline deficiencies from a regulatory standpoint.
“Our client had outstanding past exceedances that had not been remedied properly. We helped them get back into compliance and mitigate potential future issues that could have resulted in fines,” Sim says.
When SCSeTools was created, the primary goals were to standardize data acquisition and ensure that the data was secure. It was used internally at first, at a few landfills. Clients began asking for it, and now the toolsets are leveraged at over 650 locations across the country, both by SCS and clients who operate their sites.
Ensuring Data Integrity – Simplifying Processes
It continues to evolve, with one of the early advances being encryption of data collected in the field, which means that it can’t be modified when transmitted to the app.
Before, there could be errors if a file was interrupted or data mishandled as it moved along the chain of custody, explains Oliver Early, the product manager of SCSeTools.
“And now we have taken the capabilities even further,” says Brooks Ballentine, SCS director of Software Development.
“Today, we are enhancing MobileTools so field technicians can enter and transmit data directly from their mobile device to SCSeTools. This not only ensures data integrity but simplifies the process,” he says.
Data integrity and ease were the front and center focuses while designing each feature and function. Another example of this is that the software enables gas measuring instruments to be configured to align with well configurations.
“Every gas well has a unique configuration, and they are often reconfigured. Because we can synchronize the configurations from eTools to each technician’s instrument, we end up with more accurate, consistent readings, when, before, that was impossible,” Early says.
Staying On Top of Timelines
Operators must stay on their game to keep up with regulated monitoring timelines, whether involving activity at wells, monitoring probes, or flares. Some sites have hundreds or even thousands of data points with individual data timelines and, what’s more, those timelines can change. DataServices, in particular, works to simplify the detail-heavy process. It supports operators in better managing prescribed monitoring events in a couple of ways: by enabling them to view data for a specific monitoring period and by allowing them to set events to align with mandated periods.
So, if systems were out of compliance and now have to be monitored more often, the frequency can be set accordingly.
In addition to DataServices, with its robust capabilities around managing landfill gas systems data, the SCSeTools suite features two more modules: the leachate and groundwater modules. These tools are designed to support processes established to ensure regulatory compliance, optimize operational efficiency, and save costs.
SCS Leachate provides relevant information to help determine the most efficient and economical leachate disposal methods. The app manages the input, analysis, review, and export of information such as leachate origin, volume of fluids, and sample lab results for specific collection points.
The module charts and graphs leachate data by disposal method and site or multiple sites. Then, it can determine trends in leachate disposal totals using established parameters associated with leachate management.
“Once all this data is gathered and logged, users can run reports and come up with disposal costs based on data provided by clients. We can track and trend how much operators are currently spending on leachate disposal to help them optimize liquid management and plan budgets for the next year,” Ballentine says.
SCS Groundwater tracks constituents to help manage water quality and to mitigate or remediate issues. It was developed to enhance operational efficiencies while also providing a means to validate that reporting requirements are being met.
Users can set up and track monitoring plans consisting of sampling points and required analyses at each point. They can track the datasets of constituents, as well as constituents within each dataset that they are required to monitor. These constituents can be tracked over time to determine if seepages are controlled and follow progress if adjustments are required.
Once the data is uploaded into SCS Groundwater, the app checks it against the monitoring plan to verify that all work is complete. “This is a key feature because the number of possible methods, and associated analytes, is large, and ensuring that the required testing project has been completed correctly is critical,” Ballentine says.
“We are not done”: Expanding Capabilities
SCSeTools, with its three modules and mobile app, has advanced over time to keep pace with operators’ needs in an ever-changing, complex industry, and Sim says, “We are not done. We continue to leverage new technologies and to add features and functions so that we can make the best, most cost-effective decisions possible on behalf of our clients.”
