This 2025 National Brownfields Training Conference workshop will identify and describe various brownfield capital sources ranging from brownfield-specific funding to traditional redevelopment financing. Many brownfield projects require multiple capital sources to succeed; the more difficult the project, the more needed capital sources. A deeper dive will show how sources can integrate and be stacked, used sequentially for the various stages of redevelopment, and combined with private investment.
This workshop offers more than just a list of capital sources. Capital sources will be described and presented in a “generic” matrix showing the stack and sequence possibilities in the first half. Then, in the second half of the workshop, we’ll collectively work through Stack & Sequence project scenarios to demonstrate the wide range of possibilities for brownfield redevelopment funding/financing programs.
This SCS workshop accommodates individual sites and broad areas in urban and rural scenarios. Public agencies and non-profits will benefit by learning how to best promote redevelopment through utilizing multiple capital sources. Additionally, practitioners will gain insights, tools, and strategies for working with developers and investors and cultivating successful public-private partnerships that support communities’ neighborhood revitalization goals.
Eric Williams of SCS Engineers presents this Brownfields University pre-conference training event designed to provide a curriculum of core brownfields concepts and practices before the full educational program content. Eric will be providing his “Stack & Sequence – Strategically Using Multiple Sources of Brownfields Funding” training module, a popular session and the subject of multiple papers and presentations.

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.

SCSers are excited to celebrate our clients who continue to make great strides toward sustainability this Earth Day. As one of the nation’s top environmental consulting and construction firms, SCS Engineers has been dedicated to helping companies develop sustainable solutions that balance today’s financial, environmental, and bureaucratic challenges since its founding a few weeks before the very first Earth Day in 1970. Below, we’ll share a few examples of how our team and clients are making eco-friendly and sustainable impacts.
Chris Jimieson, PE, a project manager in our Madison, Wisconsin office, is sharing his story with our SCS Young Professionals across the U.S. He’s describing his journey from a dedicated and concerned parent observing recyclables being landfilled, to teaching and engaging students, and now to developing policy around district recycling in the Madison Metropolitan School District. It’s a win-win for Madison and our Young Professionals!
The City of San Diego implements a waste reduction program that funnels unsold grocery store inventory to non-profit food programs for distribution to the community. In addition to directly benefiting the people of San Diego, this program resulted in a significant decrease in food waste in local landfills, thereby increasing the lifespan of those landfills and reducing the cost of that utility over time.
A power company using coal (many still do as they transition to renewable energy sources) has taken several eco-friendly steps, optimizing the sustainability of both the plant and the company. They’re now desulfurizing flue gas, preventing air pollution and creating a by-product to make gypsum. And fly ash, another by-product of creating energy, is now being sold to concrete companies for reuse. Wastewater is pretreated for safety and chemical characterization during the permitting process, and regular sampling during operations ensures fluids are non-hazardous and unchanged. These modifications have allowed them to provide energy at a reasonable cost, qualify for government incentives offered to companies that employ green practices, and protect health and human life. That’s sustainability!
Technology is impacting the waste management industry in amazing ways, too. Drones with sensors can fly over a landfill, detecting methane leaks and allowing technicians to visualize below-the-surface conditions. The result is safer, faster, and more efficient landfill operations. Captured methane is turned into Renewable Natural Gas as a clean-burning energy or fuel source. Special sensors and automation can remove organic waste reused as by-products to create compost. Plastics, paper, and cardboard become new products. The use of technologies significantly cuts the amount of greenhouse gases that once went airborne after being buried in a landfill. All you need to do is recycle!
Finally, we’re also excited to be joining an array of Earth Day 2025 community events nationwide and globally – you can too! Find an event close to you here!
Together with our clients, SCS Engineers remains committed to advancing sustainable practices that make a meaningful difference. This Earth Day, and every day, we celebrate progress, partnership, and the promise of a greener future.
SCS Engineers expands environmental solutions in Utah by welcoming Thomas P. Gordon as a senior project manager to the firm. Mr. Gordon leads full-service due diligence site assessment and hazard remediation practice for municipalities and public and private clients in the state from SCS’s Salt Lake City office.
“Tom joins SCS as a fully certified and tested professional with over two decades of expertise and specialization in petroleum, agricultural, and mining remediation. He works closely with all stakeholders and Utah’s Department of Environmental Quality CERCLA Branch,” states Justin Rauzon, SCS’s National Expert on Environmental Due Diligence.
SCS Engineers has supported industries and businesses nationwide seeking remediation solutions for over 50 years. All require thorough due diligence to keep project development and implementation on schedule and within budget. Today’s real estate transactions must consider environmental issues, as state growth is often exhausting Greenfields or virgin land. Complex laws can impose significant environmental liabilities on purchasers, sellers, and lenders, regardless of whether they caused contamination or still own the property.
Comprehensive services provided by certified experts, such as Tom Gordon, significantly reduce the risk of funding and development for commercial properties and are especially important for mixed-use and residential reuse projects. Typically, the most strategically located properties, often formerly used by an industry, business, or municipality, may have left behind trace amounts of hazardous materials at levels no longer acceptable under federal, state, or local regulations.
Purchasers must demonstrate that they have taken reasonable steps to mitigate the effects of hazardous substances on the property, utilizing comprehensive services; that’s where Tom Gordon and SCS Engineers provide valuable support. Mr. Gordon guides clients through the necessary steps based on an Environmental Site Assessment (ESA) and a due diligence report. Regardless of the complexity of the ESA results, the combination of environmental engineers, consultants, and contracting capabilities at SCS will provide purchasers with the most cost-effective and safe solution for fully remediating the property. Clients are covered from permitting through implementation and operational monitoring.
Mr. Gordon’s degrees, certifications, and licenses include an MBA from the University of the Pacific and a BS in Environmental Studies from the University of Utah. He holds certifications for HAZMAT (ACM, LBP, PCB, DEHP, and Mercury), Storm Water Pollution Prevention Plan (SWPPP), 811 Pre-Dig, and Permitting, as well as OSHA 40/8-Hour HAZWOPER. He holds the following Utah licenses: Groundwater and Soil Sampler, Asbestos Management Planner and Inspector, and General Contractor B100. His federal licenses include Underground Storage Tank Contractor, Lead Inspector, and Department of Transportation/Aviation Remote Pilot.

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.

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.
