A large petrochemical manufacturing facility in the Midwest requested that Trihydro provide compliance determinations and recommendations regarding Miscellaneous Organic National Emission Standards for Hazardous Air Pollutants (MON) Leak Detection and Repair (LDAR) requirements. The project included developing an equipment and piping list to track organic hazardous air pollutant (OHAP) determinations for more than 1,500 transmission lines. Trihydro also identified and characterized a miscellaneous organic chemical processing unit (MCPU) and the associated 900 affected pieces of equipment.

To manage the volume and detail of supplied data, Trihydro used a relational database to form a comprehensive program based on:
This effort greatly reduced the potential for errors in reporting while adding the prospect of expandability.
The database is configured to operate through an online interface, allowing the client to access a secure website for data and applicability determinations for each piece of equipment and transmission line. To support the determinations, the project team imported stream composition data and provided physical locations for each piece of equipment and transmission line.
Upon project completion, the client asked Trihydro to complete a parallel database review of information previously reviewed by the Environmental Protection Agency (EPA) during an audit to verify EPA findings. Trihydro also assisted the client with a field verification project, phenol unit LDAR inventory and tagging effort, and a database conversion.
