On May 16, 2024, the EPA published its "New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I & II Polymers and Resins Industry" rule. Facilities impacted by the rule are required to implement fenceline monitoring for pollutants like benzene, 1,3-butadiene, chloroprene, ethylene dichloride, ethylene oxide (EtO), and vinyl chloride.

Achieving and maintaining compliance with these evolving regulations can be complex and cost-intensive, requiring a strategic approach that balances business objectives with regulatory requirements. Leveraging our extensive experience from the 2018 Refinery Sector Rule, Trihydro's comprehensive fenceline monitoring services, software and programs are designed to help you navigate this challenge efficiently and effectively. From program implementation and monitoring to data management and reporting, our air compliance experts are ready to guide you through every step.

Pilot Study Preparation

With fenceline monitoring required to begin by July 15, 2026, Trihydro helps facilities conduct pilot studies to assess site conditions. These studies aim to identify potential sources and implement corrective actions before data is made public through EPA's required quarterly CEDRI reporting.

Sample Station Siting

Trihydro aids in establishing fenceline monitoring networks per EPA Method 325A. Regardless of facility layout, our experienced team designs and implements networks meeting regulatory requirements. Our expertise ensures optimal data collection, even in diverse layouts with geographically complex elements.

Compliance Manual Development

We assist our clients by preparing compliance manuals that document the basis for sample station siting and provide step-by-step procedures for sample collection, handling, and reporting. This approach streamlines operations, improves data quality, simplifies compliance reporting, and reduces non-compliance risks.

Field Data Collection

Successful field data collection relies on a rigorous protocol, including consistent sampling procedures following the designated route, and one tube at a time sampling. Our experienced technicians, well-versed in meticulous and consistent collection protocols, are prepared to implement the monitoring procedures outlined in the new HON rule.

Streamlined Laboratory Coordination

Leveraging established relationships with laboratories nationwide, we ensure efficient sample handling and analysis. This minimizes delays, whether we contract directly with the lab or facilitate client-lab communication.

Data Management Solutions

Utilizing Fenceline ProTM, we seamlessly set up new programs or integrate existing data. This end-to-end compliance and data management tool helps reduce the amount of time that our clients spend managing the data and preparing reports for their fenceline monitoring program.

Root Cause Analysis and Corrective Action Implementation

Our success in identifying and mitigating emission sources extends to the new HON rule. Utilizing investigative techniques, such as additional sampling, optical imaging, and real-time monitoring equipment, we can pinpoint emission sources for targeted corrective action, reducing emissions and ensuring compliance.

Our Fenceline Monitoring Software

Leveraging decades of regulatory experience, Trihydro developed Fenceline Pro to tackle the complexities of fenceline monitoring with a comprehensive software solution. This user-friendly platform empowers facility personnel to accurately and efficiently collect, monitor, and report fenceline monitoring data, ensuring compliance with EPA Clean Air Act regulations.
