LDAR Compliance

LDAR Inspection Software Built for Refineries & Chemical Plants

Manage component inventories, run mobile Method 21, OVA, and optical gas imaging (OGI) surveys with camera verification built in, track every leak to a verified repair, and generate audit-ready LDAR reports — all from one field-ready platform designed for the complexity of industrial facilities.

Complete LDAR Program Management

Component Inventory Management for LDAR Programs

Track every tagged component with full attribute set: tag ID, component type, process unit, service classification, and monitoring frequency. LDAR points can carry two independent schedules at once (OVA and Method 21).

Mobile Method 21 Inspection Surveys

Inspectors follow a logical path through the unit rather than working from an unsorted component list. The interface is built for gloved hands and field conditions. Method 21 mode enforces a background reading first, requires an instrument (PPM) reading per component, and automatically records a leak when a reading exceeds the configured leak definition.

LDAR Instrument Calibration

Registry of monitoring devices (e.g., TVA 1000) by serial and model number, and of calibration gases with concentration, lot number, and expiration date. A guided four-step mobile calibration wizard: device setup → gas selection → readings → response factor and submit. One calibration automatically links to all Method 21 inspections active at the time.

Automated Leak Detection Thresholds & Alerts

Set leak detection thresholds for each component type and service classification. The system automatically flags exceedances, generates leak work orders, and alerts the right people — ensuring no leak goes unaddressed past its monitoring interval.

Corrective Action & Repair Tracking

Leak findings automatically create corrective action records with severity classification. Assign repair responsibilities and regulatory deadlines — the record follows the leak from identification to verified repair, documenting itself at every step.

Skip Period & Alternative Work Practice Tracking

Document skip periods and alternative work practices with full audit trail. Track expiration dates and receive advance notifications so compliance is never interrupted by administrative oversight.

LDAR Compliance Reporting & Audit Records

Generate compliance reports, component summary tables, and leak rate documentation ready for regulatory review. Maintain an immutable audit trail of every inspection, finding, and corrective action.

Built for the Complexity of Industrial LDAR Programs

LDAR programs at refineries and chemical plants involve thousands of tagged components across multiple process units, each with different monitoring frequencies, service classifications, and regulatory subparts. Managing this complexity with spreadsheets and paper forms creates risk — missed inspections, undocumented skips, and compliance gaps.

EHSTracks centralizes your entire LDAR program into a structured digital workflow that handles the complexity so your team can focus on what matters: keeping your facility compliant.

Whether you're managing standard fugitive emissions or specific Subpart OOOOa LDAR compliance, understanding what is EHS compliance software and how it handles these scenarios is vital to minimizing risk.

  • Inline inspection of all components on one screen for efficient unit walkthroughs
  • Method 21 mode enforces background readings and automatically records leaks
  • Flag components removed from service, in non-applicable service, or physically inaccessible with full audit documentation
  • Field-optimized interface built for gloved hands and outdoor conditions
  • Offline capability for large industrial sites where connectivity is limited

Efficient Unit Inspections

All components on one screen for efficient unit walkthroughs. Interactive satellite map shows every component as a status-color-coded pin. Tap a pin to jump to that item in the list.

GPS Distance Verification

If the inspector's GPS position is too far from the component's recorded location, the app requires a written justification before the form unlocks. Deviations are reportable for manager review.

Corrective Action Accountability

Every leak's repair progress logs itself as technicians work. Notifications keep repairs on deadline, and managers remotely verify progress — the compliance record is complete the moment the repair is.

Optical Gas Imaging (OGI) Inspections

OGI surveys need more than a list of leaks. They need a record of which camera was used, proof it could see gas that day, and the video behind every finding. EHSTracks captures all of it in the field, offline, on the same app your Method 21 inspectors already use.

Camera Verification Before Every Survey

Each time an inspector starts an OGI inspection, the app opens a two-step camera verification. Step 1 records the camera: serial number, model number, lens length, and field of view. Step 2 records the test gas release, whether it was visible, ambient temperature, atmospheric conditions, viewing distance, maximum viewing distance, initial wind speed, and the operator’s OGI qualification.

OGI Camera Registry

Keep every optical gas imaging camera on file by serial number, model, lens length, and field of view, with calibration certificates or reference videos attached. Inspectors pick their camera from the list in the field, even offline. A camera added by hand on the phone joins the registry automatically.

Camera Verification Records

Every verification lands in a sortable, filterable web table tied to the inspection it supports, exportable to Excel. Administrators can correct the date, camera, or answers without losing who performed the check in the field.

Multiple Deficiencies per Inspection Point

One location can have more than one leak. Inspectors add a separate deficiency for each problem they see, each with its own notes, priority, and up to three photos, and each becomes its own Repair.

OGI Video on the Repair Record

Attach the video clip straight to the Repair: standard MP4, MOV, M4V, and AVI files, or the radiometric recordings OGI cameras produce (CSQ, SEQ, and ATS). What the camera saw stays with what was done to fix it.

Same Platform as Method 21 and OVA

OGI surveys run on the same facility and the same app as your Method 21 and OVA inspections. Mapped inspection points, Frequency Group scheduling, offline field inspections, pre- and post-inspection questions, and repair attempt tracking all work the way they do across EHSTracks.

LDAR Software FAQ

Does EHSTracks support OGI (optical gas imaging) inspections?

Yes. OGI is part of EHSTracks LDAR and runs on the same offline-first mobile app and web administration as Method 21 and OVA inspections. Inspectors verify their camera before each survey, inspect mapped points, and record each deficiency they find as its own Repair, with photos on the phone and the OGI video attached to the Repair on the web.

What does the OGI camera verification record?

The camera used (serial number, model number, lens length, and field of view), a description of the test gas release, whether the inspector could see it, ambient temperature and units, atmospheric conditions, viewing distance, maximum viewing distance, initial wind speed, and the inspector’s OGI qualification. Verification runs every time an OGI inspection starts and can be rerun mid-day when an inspector switches cameras.

Can I attach FLIR or other OGI camera files to a leak repair?

Yes. Each Repair holds one video attachment, and EHSTracks accepts standard video (MP4, MOV, M4V, AVI) as well as the radiometric recording formats thermal and OGI cameras produce: CSQ, SEQ, and ATS. Camera files download for viewing in the camera manufacturer’s software.

Can one facility run OGI and Method 21 surveys together?

Yes. A facility can run OGI surveys alongside Method 21 and OVA inspections. Each keeps its own inspection points, schedules, and Repairs, and all of them appear on the same facility dashboard.
