Recently, Donald Trump issued four executive orders extending Clean Air Act – NESHAP compliance deadlines for a number of specific facilities that provide medical equipment sterilization, burn coal to make electricity, manufacture certain synthetic chemicals, or mine taconite. The big headline is the EPA announcing plans to rescind the ‘endangerment finding’ that allows climate regulation. However, at the same time coal combustion residuals rules are being changed. This Regulatory Alert contains language from the four executive orders, which includes a list of the specific facilities that have been granted extensions to comply. In each order, the President finds that the technology required is not available and that it is in the interest of national security to provide the extensions.
Normally there is a notice-and-comment rulemaking under the Administrative Procedures Act to extend deadlines. If the courts allow the President to continue invoking national security we may see more such executive orders modifying regulations. Follow SCS Engineers on social media to read our SCS Technical Bulletins, which summarize regulatory proposals and changes for public and private entities.
As the regulatory landscape continues to evolve, proactive planning is critical to preserving flexibility, value, and mitigating risk. We encourage businesses to consult with environmental engineers and consultants and their legal counsel to navigate these changes for continued sustainable success.

Remote Monitoring and Control Return on Investment Based on Case Studies in the U.S.
Environmental and industrial operators face mounting pressures from complex issues like tightening regulations, rising compliance costs, persistent labor shortages, and aging infrastructure. In this environment, traditional monitoring and maintenance methods, such as manual readings, paper logs, and in-person inspections, often fail to meet the demands of modern operations.
Facilities increasingly adopt Remote Monitoring and Control (RMC) systems to bridge the gap. RMC systems, originally developed to support gas and liquid management in the waste sector, now play a critical role in automating environmental compliance, optimizing equipment performance, and delivering real-time data insights across various facility types. These technologies deliver continuous data, enable remote access, and support faster, more informed decision-making. From pump stations and blowers to temperature and emissions monitoring, the shift to RMC offers not just better oversight but substantial cost savings.
Here, we highlight three real-world case studies where RMC deployments led to measurable financial return on investment and operational gains.
Cutting Air Monitoring Costs at an Industrial Facility
Air monitoring is critical to environmental compliance for landfills, renewable natural gas (RNG) operations, and solid waste facilities. These sites can emit volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) through various processes, including waste decomposition, gas destruction, and material handling. Regulatory agencies require continuous or periodic monitoring to assess pollutant levels, ensure public health protection, and enforce site-specific permit conditions. Failure to comply can result in substantial fines, heightened regulatory scrutiny, and reputational harm.
Regulators required continuous air quality monitoring for a volatile organic compound and a hazardous air pollutant at one industrial site. Manual sampling, performed daily, was costing the facility roughly $1,000 per day. Compliance was non-negotiable, but the cost was becoming unsustainable.
SCS Engineers installed a $90,000 RMC air monitoring system with seven wireless air sensors and a meteorological station. The system automates alarms, regulatory reporting, and historical data logging, all now accessible in real-time.
Within three months, the system paid for itself and saves the client an estimated ~$365,000 annually. Beyond that, it provides peace of mind. Since the system was implemented, the site has avoided regulatory fines, thanks partly to the transparent, consistent data reporting regulators now receive automatically.
Preventing Leachate Tank Overflows and Overbilling
Leachate is the liquid that drains from or through a landfill and contains a complex mix of organic and inorganic compounds, including heavy metals, ammonia, and pathogens. If not properly managed, leachate can contaminate groundwater, damage infrastructure, and trigger costly environmental violations. Closed, unstaffed landfills continue to generate leachate that must be regularly monitored, stored, and hauled away for treatment. Regulatory requirements typically mandate accurate volume tracking, overflow prevention, and timely reporting to demonstrate compliance and mitigate risk.
One SCS client operated a closed landfill with an above-ground leachate tank. With no staff on-site, they faced two persistent problems: haulers had no visibility into daily volumes, leading to inefficiencies and billing confusion, and during winter, the risk of frozen pipes or tank overflow posed serious compliance and environmental hazards.
For $30,000, SCS implemented an RMC system that provided haulers with mobile access to real-time tank levels and flow data, saving the client an estimated $10,000+ annually. Adding new alarms to flag leaks, freezing temperatures, and meter fouling, problems that had previously gone undetected until damage occurred, led to an increase in the efficiency of hauler dispatching, the elimination of billing disputes, and the prevention of at least one major overflow event by the early warning system. “Without a doubt, the system paid for itself through reduced O&M costs and prevented environmental issues,” said one SCS project manager, who quoted an ROI of roughly 1.5 to 3 years, depending on site-specific variables for a system like this.
Automating Flare Restarts at a Closed Landfill
Gas collection and control systems are essential at landfills to manage the decomposition of organic waste, which generates methane, a potent greenhouse gas. Flares are a critical component of these systems, used to combust excess landfill gas and maintain regulatory compliance with air quality and greenhouse gas standards. Reliable flare operation is not only required by permits but also essential to prevent the accumulation of subsurface pressure and potential emissions. Frequent flare-outages can result in safety concerns, odor complaints, noncompliance penalties, and costly emergency callouts. At unstaffed or remote landfills, delays in flare restarts can be especially expensive and disruptive.
At a separate closed landfill, the client spent as much as $35,000 monthly on callouts to manually restart a flare system that frequently shut down due to power fluctuations. Each visit required a time-consuming and costly process in which an employee was required to drive to the site, reset the system, and monitor the restart.
SCS installed an RMC solution costing approximately $85,000, enabling remote flare monitoring, alarm, and restart. With the new system in place, staff could respond immediately from any connected device, eliminating the need for site visits.
The anticipated monthly savings? Roughly $30,000. The investment was a clear financial win with a projected payback period of less than three months.
Efficiency That Pays for Itself
As environmental compliance becomes tighter, labor markets shift, and equipment costs rise, operational efficiency is no longer a luxury; it’s a necessity. Whether you’re operating a landfill, a manufacturing facility, or an industrial site, the pressures are the same: reduce costs, maintain compliance, protect your workforce, preserve your infrastructure, and get a return on your investment.
RMC systems address all these pressures simultaneously. From automated gas monitoring at a landfill to VOC and HAP air monitoring at a facility to liquid hauling validation at an industrial facility, RMC systems are helping operators transform data into action and costs into savings.
In industries where budgets are scrutinized and return on investment must be proven, RMC makes a compelling case. It’s a solution that pays for itself, sometimes within months, while laying the foundation for long-term performance and resilience. The opportunity to modernize and save is right at your fingertips.

Power Plants: 40 CFR Part 60, [EPA-HQ-OAR-2025-0124; FRL-12674-01-OAR], RIN 2060-AW55
On Wednesday, June 11, 2025, the U.S. Environmental Protection Agency (EPA) proposes repealing all greenhouse gas (GHG) emissions standards for fossil fuel-fired power plants. The EPA proposes that the Clean Air Act (CAA) section 111 requires it to find that GHG emissions from fossil fuel-fired power plants contribute significantly to dangerous air pollution as a predicate to regulating GHG emissions from those plants, which the current administration does not agree with.
The EPA is further proposing to make a finding that GHG emissions from fossil fuel-fired power plants do not contribute significantly to dangerous air pollution.
The EPA is also proposing, as an alternative, to repeal a set of requirements that includes the emission guidelines for existing fossil fuel-fired steam generating units, the carbon capture and sequestration/storage (CCS)-based standards for coal-fired steam generating units undertaking a large modification, and the CCS-based standards for new base load stationary combustion turbines.
EPA is proposing to repeal certain amendments issued in 2024 to the National Emission Standards for Hazardous Air Pollutants for Coal- and Oil-Fired Electric Utility Steam Generating Units – a rule commonly known as the Mercury and Air Toxics Standards for power plants, or simply MATS. This proposal would revert to 2012 standards for air toxic pollutants from coal- and oil-fired power plants.
This action proposes to relieve all facilities of the more stringent filterable particulate matter (PM) emission standard for coal-fired EGUs, the tighter mercury standard for lignite-fired EGUs, and the requirement to use PM Continuous Emissions Monitoring Systems (CEMS).

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.

Determining actual fugitive landfill gas/methane emissions from the landfill surface is hard to quantify. Drone methane and surface emission monitoring conducted on the landfill surface can determine methane concentrations at receptor points around the landfill surface. These receptor concentrations can be used to run an air dispersion model in reverse to solve for the emission rate of the entire landfill surface. This method also allows you to determine a more accurate control efficiency of the gas collection and control system at the landfill based on landfill gas/methane flow to the combustion device.
