LDAR Compliance

LDAR Inspection Software Built for Refineries & Chemical Plants

Manage component inventories, conduct mobile Method 21 and OGI surveys, track leak thresholds, 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.
