Landfill Gas Information Management

 

SCSeTools® – Developed by Landfill Gas Practitioners for Landfill Owners and Operators

The Birth of LFG Data Tracking

In the early 2000s tracking landfill gas data at facilities was anything but uniform, organized, or secure. The industry was using various methods to track data on paper forms and logbooks, then transferring it by hand into spreadsheets. Some of us used desktop database applications, but as the saying goes, necessity is the mother of invention.

From an SCS employee’s idea for demonstrating how to use landfill gas monitoring data to analyze and pinpoint system corrections, SCS DataServices® was born. In the span of several months, a team of SCS’s landfill engineers, field technicians, and technology gurus worked with client-needs to create a concept application visualizing collected landfill data on maps. Our staff field-tested it with good results, and SCS Field Services began using the application to visualize issues with wellfields that aren’t readily apparent when looking at spreadsheets.

A large SCS landfill client had seen our field staff using DataServices, asked if SCS would consider providing them with access to the application on a subscription basis. Our team adapted DataServices, added features, and continued improvements tailored for the client’s use.

As soon as secure data transfer became feasible, SCS moved to an Internet-based solution for our landfill gas practitioners. The platform called SCSeTools® holds the data collected by SCS DataServices®.

Applications and features roll out as we continually update and upgrade, incorporating ideas and improvements from our users and staff along the way. DataServices is addressing the landfill gas management needs of over 600 landfills across the US and Canada in 2021.

The keys to success follow our mission and values of maintaining close communications with our clients, field staff, engineers, and eTools support staff (all landfill gas practitioners), with the help of software engineers. Technology companies are not up at night thinking about landfill operations, but we are.

We introduce our SCS eTools landfill technology capabilities and a few of the creative and talented SCSers behind the technology in the next segment. Our speakers walk you through demonstrations of how over one-third of the landfill owners and operators in North America are increasing efficiencies using SCS eTools.

 

Visualizing Landfill Challenges – Shortcuts to Keeping Your Wellfield in Balance

DataServices shows the entire wellfield for any monitored parameters and zooms in on troublesome areas or wells. Results can be as simple or detailed as the landfill owners’ environmental and business needs dictate. The detailed examples here illustrate how graphs, maps, and charts help keep the wellfield in balance. We link each challenge to the description of a video demonstration.

In balance means extracting more gas for renewable energy, preventing odors and methane migration, keeps subsurface and surface conditions and workers safe. The information can help diagnose equipment conditions before they become costly, maintain regulatory compliance, and support cost estimates if the landfill is expanding or more infrastructure investment or equipment is needed.

Looking at vacuum distribution across a gas collection system – Select the system pressure map, which highlights vacuum distribution across the wellfield to show the wells with good (expected) vacuum, pressure drop over distance, and any wells unexpectantly losing vacuum.  Zooming in and changing the vacuum ranges further enhances where to assign staff to troubleshoot any identified issues.

Using a methane distribution map shows whether the wells are tuned to where the landfill owner wants them. Wells may be identified below the targeted range, indicating slight over pulling; a technician can use this map to identify such issues and quickly check the identified wells. Wells identified above the desired methane tuning range indicate wells not collecting enough gas, which has consequences. These wells can be the source of odors, leachate seeps, possible lateral migration to an out of waste probe. Not sending enough fuel to a power plant or atmospheric releases can affect surface emissions monitoring.

Managing liquids – Changing waste streams and more rainfall in certain areas of the country complicates liquids management. DataServices visualizes the impacts of liquids on wells and helps landfill owners better manage a proper liquids removal program.  The program will let them know how many pumps to budget for and, over time, where to relocate well dewatering pumps so that they are most efficient at removing liquids from landfills.

High-BTU Gas Plants –Filter maps help users locate wells contributing to gas dilution into renewable energy plants. It can help create punch lists for landfill staff to investigate, troubleshoot and tune. As wellfield technicians make corrections, they show on the map in real-time.

Temperature and subsurface oxidation events – Some call the condition subsurface fires, but this is a serious issue for landfills. Over-pulling wells, damaged infrastructure, and other conditions can cause oxidation events. Using a combination of temperature Parameter Maps to review wellhead temperature distribution and a Points Chart feature provides a deeper dive into the data. It provides more insight into which well or wells may be contributing to the high-temperature issues.

Locating a specific well – That’s not so easy when hundreds of wells surround you and at larger landfills. DataServices had built-in filter features to identify a single monitoring point on a wellfield map easily.

Customizing for compliance, best practices, and rules – DataServices allows monitoring points across a single site to have customized rules for each monitoring point. Rules can be for regulatory purposes, standard operating procedures, best management practices, and even site-specific preferences or any combination thereof. It is efficient to customize rule application to landfills and collection points – meaning wells, probes or ports, horizontal collectors. This customization capability helps organize and confirm regulatory compliance. It is especially salient with the 2021 EPA and state compliance changes for a single landfill or an organization with hundreds of landfills.

MobileForms – Inspection forms, blower flare station monitoring forms, load tracking from municipalities, incoming hazardous waste tracking, MRF bale counts are examples of paperless entry available. The data feeds directly from mobile phones to the supervisor and into the maintenance department, so staff can start cataloging and looking at what’s going on in real-time at several types of facilities. It’s available for regulators and inspections and helps reduce staff hours tabulating and centralizing the information.  Any information historically captured on a form or log attached to a clipboard can now be captured and stored electronically.  From there, it can be recovered and produced as a PDF export file or data from the forms used to trend data and help make informed operational decisions.

MobileTools – DataServices in a condensed format suitable for mobile devices. Field staff use MobileTools to save time formerly used to return to the office, transfer/transcribe the collected data and upload it to a supervisor for quality checks before storage.  Technicians can now recall the last 20 readings for any given well and review trend graphs on their phones or tablets while standing adjacent to the well they have questions about and need to access the data.  MobileTools also allows them to upload field data such as liquid level readings while the data is being collected.  The information instantly populates into DataServices and is available for review by others on the project team.

The most valuable tools are in development now for release in 2022. ARC GIS integration developed under SCS RMC® will further enhance DataServices with even better visualization and location capabilities and provide enhanced features such as allowing landfill owners to see their well as-built information and view subsurface information about their wells.

solar composting
California’s first 100% solar-powered composting facility is located on the Otay Landfill serving San Diego County.

 

In October, Republic Services’ Otay Compost Facility at the Chula Vista, California, Otay Landfill opened for business. The compost facility helps communities in San Diego County meet the requirements of California’s SB1383 law mandating the diversion of organic waste from landfills.

The composting facility designed by SCS Engineers in collaboration with Sustainable Generation operates completely off the grid using solar energy. It is the first fully solar-powered compost facility in the state and can process 100 tons of organics per day, with plans to double capacity by year-end.

Both organics recycling and reuse leaders, Republic Services hired SCS Engineers to design the Otay Compost Facility. The design uses renewable energy to run 100 percent of the composting operations at the site. The facility design includes using technologies to speed the maturation rates and reduce excessive odors. Blowers to aerate the organic material, oxygen and temperature sensors, and advanced compost cover technology produce a high-quality product.

L to R: The Republic Services Team at the Otay Landfill includes Gabe Gonzales – Operations Manager, Vidhya Viswanathan – SCS Engineers Project Director, Neil Mohr – General Manager, Marco Cervantes – Environmental Manager, Chris Seney – Organics Operations Director.

“Republic’s taken the goals of SB 1383, to reduce emissions of short-lived climate pollutants further. They’re running a sustainable facility that enables residents, businesses, and government to easily reuse and recycle more within a smaller carbon footprint than ever expected,” says Vidhya Viswanathan, engineer and project director.

As California collects and recycles organic materials from homes and businesses, local governments will use the products made from recycled organic material for compost and mulch. Recycling organic waste into compost creates a nutrient-rich soil amendment, preserving natural resources and reducing water consumption working within a circular economy. This California jurisdiction is ready for the SB1383 deadline on January 1, 2022.

“Republic Services supports California’s effort to divert food and yard waste from landfills to facilities such as this one,” said Chris Seney, Republic’s director of organics operations. “We’re grateful to SCS for their partnership in helping us bring this facility, co-located at an active landfill, to reality.”

Please watch the YouTube video to see the facility and learn more about its environmental value.

SCS Engineers is proud of helping our municipal and private clients bring the most value to their environmental solutions and communities. To learn more about SCS Engineers, view our 50th-anniversary video.

Grace Wohlford an Intern Engineer
H. Grace Wohlford an Intern Engineer at SCS Engineers since May 2020.

 

Grace attends Virginia Tech University, studying Civil Engineering, and will be graduating in 2022. We are thrilled to tell you that Grace has accepted a full-time position with SCS after graduation. Lindsay Evans of SCS Human Resources interviewed Grace to get an inside look at her thoughts about SCS’s Internship Program.

What is your title at SCS Engineers? Would you please describe your responsibilities at SCS?
My title at SCS is Intern Engineer. My responsibilities include assisting the SCS Midlothian, VA office on a variety of projects, including landfill engineering, landfill gas engineering, and mining engineering projects. I also have done a good amount of Construction Quality Assurance (CQA) out in the field. I do a lot of engineering work within Civil 3D and technical reporting for EPA and VDEQ involving landfill gas monitoring and data review.

What was your favorite part about our internship program?
My favorite part of the program is definitely the intern presentation day. Although it is certainly nerve-racking, I love being able to hear what all the other interns across the U.S. were involved in at SCS Engineers.

How would you describe our company culture?
The company culture at SCS is one of my most favorite parts of getting to work here. As an intern, I have the opportunity to be a part of a team with responsibilities and access to a plethora of resources within my Midlothian office and throughout the company. It’s awesome that all SCS personnel are willing to help from far and wide; everyone is just an MS-Teams call away. I’ve had incredible mentors at SCS who fostered an amazing learning and working environment for me.

Grace onsite
Grace is at home in the office and onsite!

What advice would you give to future interns at SCS?
My biggest piece of advice is never to be afraid to ask questions! As I said before, there are so many experienced professionals at SCS, and as interns, we should definitely take advantage of learning from them! Asking questions enabled me to grow and learn more than I would have had I not asked.

On what cool project have you worked?
I’ve gotten to work on tons of fun projects so far, but a notable one is using Leapfrog Works and 3D modeling. I take data given to me by either field personnel or the client and transform a model depicting gas wells within the landfill. It provides a visualization of liquid levels and obstructions to each well. This is cool because I also create surfaces from the interpolated liquid elevations, which gives a better understanding of where the liquid is most present within the landfill, which could indicate higher temperatures.

Do you feel that your work at SCS has made a difference in our environment?
It is fulfilling to know that the projects I work on, such as emissions management and monitoring, reporting, and communicating, positively affect the environment.

What have you learned the most in your internship?
I’ve certainly learned a lot being an intern at SCS since the summer of 2020. Something that sticks with me is that it’s crucial to be reliable and rely on others to collaborate and work cohesively on project teams. The best projects are successful due to the effectiveness of the project team behind them!

 

Our clients and SCSers are excited to have Grace, another amazing YP, join SCS Engineers as an Associate Professional!

containment ponds
An effective and safe solution is the evaporation or storage of the water in lined containment ponds after separation and removal of the hydrocarbon component from the water.

 

In an environmentally safe, less costly, and efficient manner, the disposal and recycling of millions of gallons of production water (brine water) and flowback water generated from the oil and gas industry annually continue to be challenging. While new technologies are on the horizon, there remains a long road ahead to their implementation.

In his article in Geosynthetic News, Neil Nowak writes in detail about three sites in Wyoming, Utah, and Texas that are evaporating or recycling water in geomembrane-lined ponds. Nowak’s article demonstrates the successful use of black high-density polyethylene (HDPE) liners to increase evaporation over clay or unlined ponds and using a white liner to reduce evaporation relative to a black liner.

Each project has been operational for several years; they continue to expand under their permits. Nowak takes us through a combination of favorable factors to the evaporative process, including the natural characteristics of each sites’ climate and the business and environmental goals.

The projects are interesting in that each facility provides oil and gas production companies in the area with a large commercial alternative to production water and flowback disposal versus numerous small ponds or disposal via injection wells.

SCS Engineers Environmental Consulting and Contracting
SCS Engineers uses specialized teams for solar implementation on landfills and Brownfields, remediation due diligence and restoration, and biogas and agricultural feedstocks for clean energy.

 

On September 15, Governor Pritzker signed Senate Bill 2408, forming the Illinois Energy Transition Act.  The Act advances renewable energy goals and the path to carbon-free electricity generation by 2045. To say this bill will impact the Illinois electrical utility landscape is an understatement.

Illinois is a top energy producer and consumer in the upper Midwest. The Act requires displacement of more than 6,000 MWh provided from coal and natural gas. One average MWh is enough to power 796 homes for a year in the U.S.

Energy efficiencies and implementing alternative energy resources will be an increasingly important strategy to mitigate the cost impacts from this Act to all users: residential, commercial, industrial, and municipal.

SCS supports clients with the decommissioning and legacy management of coal-fired facilities and renewable energy development. Our environmental team in Illinois includes local experts, Scott Knoepke and Richard Southorn who support the management of coal-fired facilities with Coal Combustion Residuals (CCR) and assist utilities transitioning to renewable natural gas installments and solar energy sources. For coal-fired facilities with CCR impoundments, SCS’s Illinois Office provides design, closure, construction quality assurance, and site stewardship (e.g., long-term maintenance, groundwater monitoring, and reporting).

SCS uses a specialized team for solar implementation on landfills and Brownfields. Knoepke and Southorn are supported by SCS National Experts in the region to assess and implement Solar Energy on Landfills & Brownfields.

The Act defines that landfill gas produced in Illinois as a renewable energy resource. SCS Engineers has one of the longest and most successful Biogas practices in the United States. SCS designs, constructs, and operates more Biogas, Anaerobic Digestion, Renewable Natural Gas, Ag Digester systems than any other engineering firm in the nation.

Waste Management Characterization
Waste characterization studies help businesses, government planners, haulers, and recyclers understand what’s in their waste streams, a first step in devising ways to reduce waste and cut disposal costs.

 

Recently the state of Wisconsin released its updated 2020-2021 statewide waste characterization study. The study found that the broad organics category, including yard waste and diapers, accounted for about 1.3 million tons. An estimated 924,900 tons of paper, including cardboard, compostable and office paper, comprised about 21 percent of the landfills’ tonnage. That was followed by plastic at about 17 percent or 745,600 tons.

You can read the study, but why do local governments, states, and waste management businesses request these studies? Because waste and landfills are expensive to manage. Diverting waste from landfills cuts greenhouse gases and supplies materials for reuse as new products or compost – a more sustainable system.

Waste characterization information is designed for solid waste planning; however, anyone interested in the characteristics of the solid waste stream may find it useful. Studies can also target specific waste or needs such as construction and demolition waste and business waste generators. A generator means a person, specific location, or business that creates waste.

These studies help start answering questions such as:

  • How much wasted food could be diverted for consumption or organics management?
  • How is COVID impacting recycling and recycled material feedstocks?
  • Which business groups dispose or recycle the most tons, and what materials make up those tons?
  • What is the commercial sector’s overall waste composition for disposal and diversion streams?
  • What are the detailed compositions for different groups or generators?
  • How much building debris is mixed in, and what kind of impact does it have?

States, jurisdictions, citizens, and businesses can use this information as a planning tool to help meet state mandates and their goals to reduce waste and achieve the benefits of sustainable practices. Kudos to Wisconsin, Iowa, and California, several of the many states moving toward more circular waste management!

Sustainable Biofuels

 

In August, the U.S. Department of Energy (DOE) announced nearly $34 million in funding for  11 projects that will support high-impact research and development to improve and produce biofuels, biopower, and bioproducts. These biomass resources, otherwise known as feedstocks, can be produced by municipal solid waste (MSW) streams and algae and converted into low-carbon fuels that can significantly contribute to the decarbonization of transportation sectors that face barriers to electrification, like aviation and marine.

Transportation accounts for approximately 30% of total U.S. energy consumption and generates the largest share of the country’s greenhouse gas emissions. Biofuels serve as a low-carbon alternative to petroleum and can also be used to produce carbon-heavy products like plastics, fertilizers, lubricants, and industrial chemicals.

Among the DOE recipients is a team led by Stephanie Lansing, professor in the Department of Environmental Science and Technology at the University of Maryland (UMD). Lansing is leading a consortium of scientists and industry partners to research innovative ways to use waste and to make value-added products that will contribute to the sustainability of our economy and planet.

SCS Engineers is an environmental engineering firm specializing in waste management and renewable energy from waste products. SCS is on the Lansing team focusing on biofuel production. The team includes Ohio State University, Mississippi State University, Virginia Tech, Idaho National Lab, and Quasar Energy Group. Their first task is to conduct a waste characterization study across every U.S. region during every season of the year, to understand how location and the time of year affect landfills’ incoming waste. The results help determine what the biofuel potential of that waste is.

Another Lansing team will be working toward producing bioplastics that are made without using fossil fuels and degrade much more easily than current plastic products.

The biofuel and bioplastic projects involve sustainability and economic assessments comparing them to current products on the market to see how marketable these new products can be. And the reason why Lansing’s comprehensive teams are important; they will help commercialize any new products.

Secretary of Energy Jennifer Granholm stated in the DOE August 3 press release, “The companies and universities leading these projects will ensure that our cutting-edge biofuel technologies reduce carbon emissions, create new jobs up and down the supply chain, and are made in America by American workers.”
