The EPA proposes updated effluent limitation guidelines (ELGs) for meat and poultry product facilities, aiming to reduce wastewater pollution, particularly nitrogen and phosphorus discharged from meat and poultry processing facilities. These changes affect meat and poultry industry facilities, including those that would apply to additional direct and indirect dischargers.
There is growing concern as local and state ELGs are also beginning to appear. These new guidelines can impact the meat and poultry industry and the food and beverage industry. In summary, the federal guidelines are influencing state and local plans.

Hydrogen sulfide (H2S) is often identified as a potential culprit of odors and nuisance complaints near municipal solid waste (MSW) landfills. Some base their complaints on information found on the Internet as fact. As experts, let’s start by saying data from other landfills or pulled from an AI browser summary online will not provide accurate answers. H2S concentrations vary widely and are unique to individual landfills.
How is H2S generated in an MSW landfill, and why do concentrations vary?
Calcium sulfate (CaSO4•2H2O, aka gypsum), the primary ingredient in wallboard (aka drywall), can be biologically converted to H2S under select and somewhat rare conditions. Specifically, seven conditions are required for the biodegradation of gypsum to H2S. See (Gypsum Association, Industry Technical Paper: Treatment and Disposal of Gypsum Board Waste (Jan. 1991); Gypsum Association, Treatment and Disposal of Gypsum Board Waste, Part II, Technical Paper (Mar. 1992).
Condition 1 – Liquid Water. The biological conversion of sulfate to H2S occurs in the aqueous phase—i.e., sufficient free liquids must be present, and sulfates must dissolve into the free liquids. Modern landfills with leachate collection systems may experience intermittent perched and discrete zones of saturation within the waste mass, particularly following periods of extended precipitation. Low-permeability confining layers (e.g., clay or clay-like soil used for intermediate cover) may temporarily trap water/leachate in discrete pockets within the landfill.
Condition 2 – Source of Soluble Sulfate. Gypsum, having the chemical formula CaSO4•2H2O, is a source of soluble sulfate. Gypsum sources include wallboard (aka drywall), flue gas desulfurization (FGD) material from coal-fired power plants, and some industrial wastes. Sulfates and sulfur compounds can also be present in lower concentrations in other waste streams, depending on what the MSW landfill accepts.
Condition 3 – Sulfate-reducing Bacteria. Sulfate-Reducing Bacteria (“SRB”) use dissolved sulfate as an electron acceptor in the oxidation of carbon. Primary SRB include Desulfovibrio and Desulfotomaculum. These SRBs, as well as many other bacteria, are commonly present in MSW landfills. However, the presence of SRB within a landfill may not be ubiquitous, and may be limited to regions where the other required conditions favor their existence and survival.
Condition 4 – Organic Material. SRBs use organic material as a food source to multiply and degrade sulfate to H2S. Carbon serves as a source of energy for the bacteria. Typical MSW has a high organic content due to a wide variety of organic materials such as wood, paper, cardboard, food, vegetative waste, and fabrics. Many communities with recycling programs help divert these waste materials for reuse and recycling.
Condition 5 – Anoxic Environment. SRBs thrive under anoxic (without oxygen) conditions. The presence of oxygen can kill SRBs. While anoxic conditions are typically not present in areas where MSW was recently disposed, they are typical in portions of MSW landfills where organic wastes have been present for at least a few months and decompose to produce methane and carbon dioxide.
Condition 6 – Appropriate pH Range. SRB reduction of sulfate to H2S is reportedly optimum within a pH range of about 7 to 8, and does not occur outside a pH range of about 4 to 9. The pH range within a typical MSW landfill falls within this activity range.
Condition 7 – Appropriate Temperature Range. SRB reproduction and H2S generation are reportedly optimum within a range of about 30 °C to 38 °C (86 °F to 100 °F). Many MSW landfills are within or a little above this optimum range. Studies of SRB in geologic environmental settings found reduced activity above about 60 °C (140 °F), and no activity above about 80 °C (176 °F). Similarly, SRB activity ceases in freezing conditions.
In summary, although the necessary conditions for H2S generation are likely intermittently present within some discrete pockets within many MSW landfills, the conditions are not likely ubiquitous throughout the waste. MSW landfill conditions and waste composition are typically highly heterogeneous with respect to both location within the landfill and time. Thus, there are zones within landfills where many, but not all of the seven required conditions are present, and H2S generation does not occur. For example, there are undoubtedly many regions within landfills where free liquids (i.e., saturated conditions) are not present and, therefore, SRB conversion of sulfates to H2S does not occur, despite the presence of the other six conditions.
Similarly, a landfill may have pockets where bulk sulfate-containing waste has been disposed of but where the internal portion of the pocket is not exposed to moisture, organics, or SRB—each a necessary condition for converting sulfate to H2S.
Considering these seven conditions and heterogeneous landfill conditions, there are too many variables to provide a reliable and defendable quantitative model for H2S generation at all MSW landfills.

In 2024, the EPA published a proposed regulation to revise existing Effluent Limitation Guidelines (ELGs) and pretreatment standards for the meat and poultry products (MPP) industry. The MPP industry includes meat and/or poultry slaughter facilities, further processing, or rendering. The industry also produces pet food and animal feed. In August 2025, the EPA decided not to move forward with additional ELGs or pretreatment standards for this industry. Published before this decision, you may find value in managing local or state regulations during this educational video.
Localities and states are also looking at the proposed federal guidelines to determine effluent limitations. Even though the federal proposed guidelines are aimed at the meat and poultry industry, some of the categorical waste streams could impact the food and beverage industry at the local or state levels. If meat or poultry is an ingredient, you’ll want to ensure your operation’s waste stream is correctly categorized.
Webinar Focus
SCS Engineers provided a webinar to help the industry understand the implications of ELG guidelines and its impact on local regulations. Dr. Todd DeJournett covers new regulations and stricter limits on nitrogen and the proposed phosphorus limits, pretreatment for oil and grease, total suspended solids, and biochemical oxygen demand. He also covers how your category can impact operations in the meat and poultry industry and the food and beverage industry.
Webinar Benefits
Attendees will better understand the compliance requirements, which will help determine your next steps to determine potential technical solutions, capital requirements (new equipment, & training), and the impact on operational costs from new waste streams. Early strategies are a significant asset, as states and localities are also beginning to impose stricter wastewater limitations, which could slow down the permitting process for your operation.
Who Should View and Your Privacy
The SCS webinars allow facility management, environmental, and sustainability staff to prepare for stricter guidelines.
This educational, non-commercial webinar with Q&A is free and open to all who want to learn more about EPA’s proposed effluent limitation guidelines.

Navigating Industrial Waste and Wastewater Permitting
Industrial waste and wastewater permitting involve obtaining necessary authorizations from federal, state, and local regulatory agencies before handling, treating, storing, or disposing of industrial waste. We all know that permitting ensures compliance with environmental regulations, protects public health, and minimizes potential harm from industrial activities. Nevertheless, federal mandates can change with new administrations, complicating the process and timing.
The timing for industrial waste and wastewater permitting can vary significantly depending on the specific type of permit and the regulatory authorities involved, and it is a significant cost factor. New permits may have a long approval cycle, so we provide advice to help expedite the permitting process in this article.
Stakeholder Involvement Early in the Permitting Process
Communicating the stakeholder goals upfront helps identify and address potential challenges before permitting submissions. Stakeholders include any agency involved in the permitting process, such as federal, state, and local agencies. Even the finest environmental consultant does not try to anticipate every potential issue – we work with facts.
Early communication and coordination prevent delays and provide valuable insights, perspectives, and, in our experience, innovation specific to an industry, facility, process, and locality. Aligning your permitting cycle with the needs and expectations of agency stakeholders builds trust and goodwill, smoothing the process and preventing unnecessary slowdowns to address questions.
Example: Working in Partnership with Miami-Dade County
For example, industrial facilities in Miami-Dade County must navigate a comprehensive permitting process to protect public health and the environment. For this article, we base our advice on permitting for a pet food manufacturer, an aircraft maintenance facility, and a water bottling facility – all very different but following a similar strategy. The Industrial Wastewater Facility (IW5) and the Industrial Waste Pretreatment (IW-P) Permits are among the most common and critical permits. While each serves a distinct regulatory purpose, both are essential for facilities that generate or manage industrial waste.
Facilities impacted include dry cleaners, automotive service providers, manufacturers, printers, and film processors. Understanding which permit applies and how to comply can significantly reduce project delays and keep operations on schedule.
Understanding the IW5 and IWP Permits
The IWP Permit regulates facilities that discharge significant volumes of industrial wastewater to the public sanitary sewer system. These discharges are subject to local and federal pretreatment regulations.
The IW5 Permit, the focus of this article, applies to facilities that store or use hazardous materials in smaller quantities and discharge relatively low volumes of wastewater. The permit outlines conditions that facilities must meet to minimize the volume and impact of their discharges on the County’s Publicly Owned Treatment Works (POTW).
Steps in the IW5 Permitting Process
The Miami-Dade Department of Regulatory and Economic Resources (RER), Division of Environmental Resources Management (DERM) administers the permitting process. Facilities submit required documentation through the County’s Electronic Permitting System (EPS). The process typically involves the following phases:
Before submitting an IW5 permit application, facilities must prepare and upload the following documents:
Once the CU and Occupational License are secured:
Finding the Right Environmental Consultant
The IW5 and IW-P permitting process can be complex, but partnering with an experienced environmental consultant can streamline your path to compliance. Look for a partner who supports industrial clients —from aircraft maintenance and cleanrooms to chemical R&D and clinical pharmacology—through every stage of the permitting process.
Seek a partner who will assist you with early documentation, regulatory coordination, and ongoing compliance to help ensure timely approvals and avoid costly delays. An environmental consultant with in-house experts, including legal and construction, will bring more value to your permitting project.

The Role of Environmental Engineering
As we celebrate Earth Day and honor the natural systems that sustain life—our forests, oceans, and atmosphere—it’s also an opportunity to reflect on how professionals across the environmental sector contribute to protecting our planet. Some efforts are highly visible, such as preserving endangered habitats or advancing renewable energy. Others, however, operate quietly in the background, confronting the more complex legacy of industrial development, which provides the products and services we use.
At SCS Engineers, some of our work resides in this less visible space. This work includes landfill engineering, site remediation, infrastructure development, and regulatory compliance. These aren’t the areas typically highlighted on Earth Day, but they are vital in maintaining environmental and public health—and in many ways, they represent a different kind of stewardship.
The Invisible Side of Environmental Work
To some, environmental engineering tied to waste management or development may seem counterintuitive to environmental protection. Some view landfills, brownfields, and infrastructure projects as necessary evils—problems to be managed rather than contributions to sustainability.
But that perspective overlooks our work’s critical role in restoring damaged environments, protecting communities from exposure, and shaping how to implement future development responsibly.
Our work doesn’t always look like conservation—but it is. It’s conservation through control, balance, and careful planning – sustainability.
Redemption Through Engineering
Earth Day is a time to recognize that not all environmental progress begins in pristine ecosystems. Much of it starts in places where damage has already been done—on contaminated sites, aging landfills, or underserved communities with high environmental risk.
At SCS Engineers, we work with public and private sector clients to:
It isn’t just reactive work—it’s strategic, science-driven, and essential to reducing long-term environmental risk.
A Balanced Approach to Environmental Protection
We recognize that those professionals working in the environmental sector may not always get the spotlight. It’s easy to look at a landfill and see only the waste—or at development and see only the disruption. But behind the scenes are engineers, scientists, and planners working to harmoniously ensure that our built environment coexists with our natural one.
The challenges we face today—climate change, pollution, population growth—require a wide range of solutions; some focus on protection, others on prevention, and many, like ours, on restoration and resilience.
Celebrating All Contributions the Week of Earth Day
Environmental progress is not linear. It often involves confronting the consequences of past decisions and building a path forward that prioritizes sustainability at every stage. Our work may be less visible, but it is no less critical. We are proud to be part of the team, ensuring that human advancement doesn’t come at the cost of our shared environment.
We invite you to recognize the full spectrum of environmental work this week of Earth Day. From protecting endangered species to restoring contaminated land, every contribution matters. And for those working to manage what others might overlook—we see this as our responsibility and our opportunity for impact.
If your organization is navigating complex environmental challenges or seeking ways to manage growth, waste, or remediation responsibly, we’re here to help. If you want a satisfying career where your work matters, join us!

Over the past 55 years, SCS Engineers has established a leadership role in comprehensive solid waste management and environmental services, which would not have been possible without the support of our municipal clients and industry. There were fewer than a handful of engineering firms specializing in environmental consulting when SCS was founded in 1970.
Today, the firm supports a wide range of environmental solutions in different industries and business sectors. Fifty-five years ago, no one could have imagined using drones and satellites to collect information for landfill operations or utilizing carbon sequestration in an environmentally safe manner. CEO Doug Doerr says:
Our greatest reward is client satisfaction. Thanks to you, our clients, SCS Engineers has received numerous awards and industry recognition for its research achievements and technological innovations, which protect human health and the environment while enhancing operational efficiency. We take pride in operating and maintaining critical environmental infrastructure that the public and businesses depend on. Our employee-owners know how to solve problems and, drawing on our deep bench of engineers, scientists, and consultants, move forward as a team.
SCS’s business model features regional and satellite offices situated near client sites, with mobile offices co-located on project sites. “The model has always worked well for us,” President Curtis Jang recently stated. “Our professionals and technicians live nearby; our distributed network means we are nearby project sites instead of flying, or working online.”
“We’re proud of the care and contributions by our colleagues over the years, and now,” states Eddy Smith, COO. “That sense of responsibility and ownership, along with SCS’s camaraderie and high-quality results, brings our clients back.”
The environmental consulting firm started as a partnership between Bob Stearns, Tom Conrad, and Curt Schmidt on April 1, 1970, in Long Beach, California. The three engineers knew and respected each other’s strengths and capabilities: Stearns was an expert in solid waste, Schmidt was a water and wastewater engineer, and Conrad was a jack-of-all-trades with experience in civil engineering, solid waste, water and wastewater.
By the late 80’s, SCS Engineers had created new specialty practices, under the name SCS Field Services, to perform landfill and landfill gas system construction, operations, monitoring, and maintenance. The firm was proud to offer comprehensive services, but it knew from its experience that each landfill and solid waste operation is unique. SCS OM&M now operates 27,500 LFG extraction wells and supports over 650 landfills across the nation. SCS Field Services Construction is a Class A – General Engineering Contractor with Hazardous Materials Certification. SCS believes that by overlapping design, construction, and operational activities, it has led to the innovations listed as SCS Firsts on their website and saved their clients money.
In 1986, the firm also made a significant and strategic decision to create an employee stock ownership plan. Chairman Jim Walsh explains, “As an ESOP company, our employees own shares in SCS Engineers and all its practices. We felt that ownership inspires better performance and that our staff deserve control in the decision-making and direction of the company. It has proven to be a successful business model for the firm.”
Combining SCS’s expertise in solid waste management, landfills, and regulatory compliance, SCS Energy was created in 2001 to focus on the design and design-build of landfill gas-to-energy (LFGE) systems. SCS now has one of the longest and most successful biogas practices in the United States, primarily in Renewable Natural Gas. SCS designs, constructs, and operates more RNG, LDFE, and DGE facilities than any other environmental engineering firm in the nation.
Growing and expanding its environmental expertise to serve other industries and sectors, SCS draws on specialized practices to continue to support a growing number of public and private clients under the SCS Engineers umbrella.

SCS clients entrust the firm with managing more than 40 million metric tons of anthropogenic CO2e greenhouse gases annually. The firm collects and beneficially uses or destroys enough methane to offset greenhouse gas (GHG) emissions from more than 8.7 million passenger cars annually. These figures do not include the significant emission reductions achieved through carbon sequestration, waste diversion, recycling, and repurposing waste into useful products, such as Renewable Natural Gas, compost, or supporting municipal programs that donate perfectly edible food to those in need.
“We attribute our success to our loyal clients who entrust us to address the complexities of environmental challenges,” says Nathan Hamm, CSO. “We are proud of our employee-owners who create the technologies, practices, and systems that make a sustainable, positive impact while being economically feasible.”
Over the years, SCS expanded and hired many talented people. They guide the firm, maintaining the founders’ focus on adopting their clients’ environmental challenges as their own and fostering a culture of success for employees by sharing equity ownership. The firm helps clients minimize waste and pollution while providing GHG-lowering carbon capture, monitoring, control, and accounting solutions, as well as sequestration solutions, with a proven ability to mitigate and remediate air, water, and soil pollution.
“SCS’s culture attracts professionals with diverse expertise, enabling the firm to grow organically. It is on track to reach nearly 1,400 employees this year and has achieved year-over-year record-breaking revenues,” says CPO Stacey Dolden. SCS’s core capabilities include solid and hazardous waste management, renewable energy, remediation, and environmental compliance and sustainability, aimed at reducing or preventing GHG emissions. Over the last two decades, the demand for SCS expertise has expanded into various areas, including remote monitoring and control technology, wastewater and water reuse, composting, sustainable materials management, industrial health and safety, and risk management planning. The firm maintains a deep technical bench, a wide range of industry experts, and extensive knowledge of federal, state, and local environmental regulatory systems, which enables clients to shorten project timelines, control costs, and meet evolving regulations.
Earth Day is also celebrating its 55th Anniversary this year – the first Earth Day took place just a few weeks after the start of SCS. We’ll be at Earth Day events around the country serving hundreds of communities, charities, and associations. We hope to see you there! SCS Engineers remains passionate about continuing to provide superior client service and solving the environmental challenges of the 21st Century.

Current State of the Regulation of Composting Facilities under Air Quality Programs with Pat Sullivan
Composting facilities are becoming increasingly regulated across the country, particularly for air quality permitting requirements. It is important to know where these requirements stand in the various jurisdictions in the U.S., so facility developers can properly plan any new facilities or expansions. Further, estimating air emissions is an integral part of the air permitting process, and many of the emission factors currently in use, and being prescribed regulatory agencies, are dated and based solely on data from open windrow composting.
The proposed presentation would include a survey of how compost facility air permitting is presently handled in various states and local jurisdictions across the country with focus on the western U.S. The types of information to be covered would include whether air permits are required and under what circumstances, how emissions are regulated and whether they are considered fugitive or not, how ancillary equipment is permitted (e.g., grinders, windrow turners, etc.), whether controls are required and what levels of control are deemed necessary, what is best available control technology (BACT) for composting, and if the agency has any specific rules for composting. The presentation will include a summary of the current state of emission factors for composting.
As part of the presentations, more detailed air permitting information would be supplied for several example air jurisdictions in California, including the Bay Area AQMD and San Joaquin Valley APCD. The examples would cover the range of complexities from the most stringent air permitting requirements to the simplest and most basic requirements.
The attendees to this presentation will learn about:
Can We Get Credit for That? with Victoria Evans and Erik Martig
To reduce GHG emissions to meet climate goals, numerous strategies encourage lowering the carbon intensity of operations and supply chains. Here, Victoria and Erik answer the question of ‘Can we get carbon credit for that?” by addressing offsetting and insetting projects applicable to waste related commodities. They focus upon compost and biochar providing relevant examples for both offsetting and insetting. Insetting involves directly reducing emissions within the company’s own operations and value chain. Victoria and Erik will provide examples of carbon accounting quantification for both project types.

Eva Luu and Armando Hurtado will be presenting “Real-Time Monitoring of Odor Using Sulfur as a Surrogate,” during the Agricultural Emissions and Odor Measurements track.
Cannabis remains a contentious topic in the United States. While a majority of Americans support legalization, challenges such as nuisance odors have emerged, complicating the landscape. Geographical location plays a significant role in the success of cannabis cultivation, particularly in outdoor and greenhouse settings, where moderate temperatures benefit crop production. These same favorable weather conditions often align with increased population density, heightening the need for effective odor mitigation strategies. Although the distinctive “skunky” odor has traditionally been linked to terpenes, recent research suggests that other compounds play a critical role.
To address cannabis odors, various mitigation methods have been implemented, including misting systems, carbon filters, and advanced scrubber units using ozone and photocatalytic oxidation (PCO).
Each of these methods can be effective for odor controls in the appropriate settings and when applied to specific cultivation methods.
While these techniques can reduce onsite odors, offsite locations frequently continue to detect the characteristic smell. Odor samples can be collected onsite and analyzed in Odor Labs, but they do not provide real-time data for cultivators to make immediate adjustments to operations.
Through meticulous planning and iterative rounds of testing, we identified total reduced sulfurs (TRS) as a reliable surrogate for real-time measurements of cannabis odors in enclosed spaces. This approach allows operators to identify odor problems in situ and take necessary action in a timely manner. The findings underscore the importance of innovative measurement techniques in improving odor management practices and enhancing the sustainability of cannabis cultivation. This work aims to contribute to a more comprehensive understanding of odor dynamics in cannabis production, ultimately assisting cultivators in effectively addressing community concerns while optimizing operational integrity.
