Facilities preparing for Appendix K optical gas imaging (OGI) monitoring requirements often face a common challenge: managing documentation, inspection data, videos and reporting across multiple systems. This often creates challenges during audits when records must be compiled or verified. Appendix K programs require structured documentation of OGI inspections, including daily verification checks, weather conditions, and video documentation.  What Data Must Be Collected for Appendix K OGI Inspections Inspection records must capture operational parameters such as: Temperature Wind speed Sky conditions Gas type Flow rate  Camera distance  This information is stored directly within the inspection record within SkyBridge, ensuring that verification documentation remains linked to the survey data. How SkyBridge Supports Appendix K OGI Monitoring and Documentation SkyBridge Software includes integrated functionality designed to support Appendix K workflows, helping environmental teams capture and manage the required documentation directly within a single platform. SkyBridge is part of Alliance Technical Group’s suite of environmental compliance software tools designed to streamline monitoring programs and reduce manual data management. SkyBridge operates as a cloud-based compliance management system, allowing organizations to manage LDAR, OGI, and Cooling Tower and Fenceline Monitoring programs in one centralized database. Core capabilities include: LDAR scheduling and repair tracking Method 21 monitoring support Visual leak documentation Visible vapor and OGI camera integration Leak management tracking Recordkeeping and LDAR reporting GPS tracking for field technicians Because SkyBridge integrates web and mobile applications, technicians can collect inspection data in the field while syncing information directly to the system. OGI Monitoring and Appendix K Verification and Documentation SkyBridge includes specific functionality designed to support Appendix K OGI monitoring documentation requirements. Field technicians can document and upload verification data directly from the inspection location, including: Daily verification check documentation and video uploads - Creating a traceable record that verification checks were completed prior to surveys, helping facilities demonstrate that OGI cameras were operating properly and that monitoring procedures were followed.  Daily field check documentation and video uploads - Ensures required checks are consistently recorded in real time, reducing reliance on manual logs and minimizing gaps in documentation. Weather and environmental conditions documentation - Captures required conditions at the time of monitoring, supporting data validity and helping avoid challenges to inspection results. Leak Image and video file documentation - Provides visual evidence of findings, improving transparency, supporting repair prioritization, and strengthening compliance records. QA Verification video - Documents quality assurance activities, reinforcing program credibility and helping facilities demonstrate adherence to Appendix K requirements. Supporting Scalable OGI and Appendix K Compliance Programs As OGI monitoring programs continue to expand, environmental teams need tools that help simplify field documentation and maintain consistent records. By combining inspection documentation, leak management, video uploads, and reporting into one system, SkyBridge provides a structured approach to managing Appendix K monitoring programs.
