For those stationary combustion turbines (SCT) where the stay was removed on March 9, 2022 (New Lean Premix and Diffusion Flame Gas-Fired Turbines), the initial performance test is required to be completed by September 5 , 2022 (180 days after the compliance date).  Due to the restricted compliance testing window and the industry-wide resource limitations for these highly complex projects, some facilities will not be able to meet the deadline for the initial performance test. Therefore, Alliance recommends consulting with your Administrator (state or local permitting authority who has delegation) to request an extension of the initial performance test leveraging either 40 CFR 63.6(i), extension of compliance with emissions standards, or 40 CFR 63.7(a)(4), performance testing extensions claiming force majeure. Additionally, Alliance recommends getting your MACT YYYY test scheduled as quickly as possible beyond the current deadline of September 5, 2022 and include this information in your extension request. Schedules after September 5 are rapidly filling and will continue to do so due to the limited industry resources. Finally, if you need support in requesting an extension, please contact Jonathan Brockhaus at the following email Jonathan.brockhaus@alliancetechnicalgroup.com

In today’s world, operating in compliance with established requirements is critical to the success of an enterprise. The cost of failure can be very high – potentially involving curtailment of operations, loss of business, hefty fines and penalties, as well as damage to the reputation of the company. Selecting the highest quality provider of testing services is the best way to mitigate this risk. The technical expertise, equipment, and methodology needed to properly measure the tightening limits for air compliance requires a deep bench of scientists, recurring capital investment, and highly skilled, trained and experienced personnel who know their jobs inside and out and know how to work safely on a customer’s site. Establishing and maintaining this capability comes with a cost, particularly in today’s inflationary environment. Often, the risk of non-compliance increases when the lowest cost provider is chosen to provide technical services.  Procurement teams using “e-auctions” or other tools that focus solely on proposal cost to select suppliers can, unintentionally, create higher risk, and, in the long term, significantly higher costs for the company.  “Lowest cost” often means undertrained, undermanned and inexperienced teams, lack of redundant equipment or even the wrong equipment being used due to a lack of industry or process-specific expertise. A quality test team measuring several target analytes from several sources often consists of multiple sample trains, two or more mobile labs, and highly qualified and experienced project managers, project scientists and technicians.  Each method being performed requires specific equipment, documented SOPs and knowledgeable technical team members who not only cross every “t” and dot every “i”, but also have the depth of real experience and judgment needed to provide the most useful feedback to the customer when processes or control equipment aren’t performing as expected. As industry continues to work towards meeting the ever-tightening limits being set by regulatory agencies, the ability to measure and report actual emissions accurately (and consistently) becomes more challenging, and therefore, requires even more emphasis on choosing your testing partner carefully. The best way to accomplish this is by selecting the highest quality provider - who may not appear be the cheapest - but is actually the one who will provide the most economical result thanks to their investments in the technology, training, equipment, and personnel needed to deliver highly accurate reports, timely proposals, and comprehensive test plans. The Alliance Advantage was created to ensure this result.  Find out more at www.stacktest.com .

Emission monitoring is a critical function for industries aiming to minimize their environmental footprint while adhering to regulatory standards. The task, however, is laden with challenges — from ensuring accurate data collection to maintaining compliance with ever-evolving environmental laws. The advent of specialized: software and modern technology has emerged as a beacon of resolution to these challenges. By harmonizing the capabilities of both, industries can now navigate the intricacies of emission monitoring with improved accuracy, efficiency, and compliance. Let's unravel the essential roles of software and technology in enhancing emission monitoring systems, revealing how they can collectively contribute to better environmental management. Accuracy and Real-Time Analysis Accurate emission data is a top priority. Incorporating software solutions can help enhance the precision of data capture and analysis. For instance, real-time monitoring systems are capable of instant data processing, enabling immediate insights into emission levels. This immediacy not only fulfills regulatory mandates but also empowers industries to take prompt corrective actions. Real-time data processing for immediate insights. Reduced manual errors through automated data collection and analysis. Automation and Efficiency Automation stands as a cornerstone in elevating the efficiency of emission monitoring systems. By automating data collection and analysis, industries can reallocate resources to other critical areas. For example, an automated system can schedule regular equipment checks, ensuring optimal functionality and accurate data capture without human intervention. Streamlined operations through automated data collection and analysis. Regular, automated equipment checks for maintained accuracy. Compliance and Reporting Navigating through the maze of environmental compliance is less daunting with the aid of specialized software. These software solutions ease the generation of comprehensive compliance reports, a task that traditionally demanded substantial manual effort. Moreover, electronic reporting has become a standard in many regions, further underscoring the importance of software in emission monitoring. Simplified compliance reporting for adherence to environmental regulations. Effortless generation and sharing of comprehensive reports with regulatory bodies. Data Management and Decision Making Effective data management is fundamental for a robust emission monitoring strategy. Software platforms offer organized storage, easy retrieval, and insightful analysis of historical emission data. This reservoir of data becomes a powerful tool in strategizing for lower emissions, demonstrating a clear trajectory of improvement to stakeholders, and making informed decisions. Organized storage and easy retrieval of historical data. Informed decision-making derived from insightful data analysis. The integration of software and technology in emission monitoring is a significant stride toward sustainable industrial operations. It encapsulates a forward-thinking approach, where automated, accurate, and efficient emission monitoring lays the foundation for environmental stewardship. As this area continues to advance, it requires closer examination and engagement from industry leaders who want to harness its full potential for a cleaner and more compliant industrial landscape.
