Compliance Scope

The facility needed defensible records for 40 CFR Part 64 monitoring after an EPA audit exposed gaps in paper-based operator logs.

Existing PLC

Allen-Bradley ControlLogix retained

Data System

Ignition with SQL historian backend

Retention

Secure 5-year rolling archive

Challenge

A chemical coatings manufacturer received a notice of violation from its state environmental agency because CAM documentation for its 3-chamber RTO was incomplete. The oxidizer had adequate temperature instrumentation, but operators were still recording readings manually on paper every 30 minutes, creating inevitable gaps whenever shifts were busy, alarms occurred, or paperwork was misplaced.

During an EPA audit, those record gaps created questions around continuous compliance under 40 CFR Part 64. The facility needed more than a historian screen; it needed a monitoring system that could capture the right process parameters continuously, identify exceedances automatically, preserve records for long-term retention, and guide operators through deviation documentation when intervention was required.

Solution

VIR Automation designed a compliance data system that integrated with the existing Allen-Bradley ControlLogix PLC rather than forcing a full platform replacement. The new architecture continuously acquired temperatures, pressures, flows, and valve positions from the RTO, then stored that data at 1-second resolution with configurable 1-minute, 15-minute, and 1-hour averages to align with reporting needs.

Ignition was used as the monitoring layer to provide automated exceedance detection, alarm logging, dashboard views, and report generation. Operators received real-time green/yellow/red compliance status indicators on the HMI, while deviation workflows prompted root-cause notes whenever a monitored parameter crossed a configured threshold. VIR also implemented secure SQL-based storage with 5-year retention and automated PDF/CSV report distribution for daily, weekly, and monthly summaries.

Continuous Data Acquisition

Temperatures, pressures, flows, and valve positions were logged continuously from the operating RTO.

Exceedance Detection

Automated event logic flagged excursions immediately and paired alarms with operator notification.

Automated Reports

Daily, weekly, and monthly compliance summaries were generated in PDF and CSV formats.

Retention & Audit Readiness

Secure storage and documented deviation workflows improved defensibility during agency review.

Results

Automated Documentation

Compliance documentation became fully automated with zero manual data entry.

Audit Support

The facility passed its next EPA audit with a complete documentation package available for review.

NOV Resolved

The state agency closed the violation after reviewing the new monitoring and reporting workflow.

Faster Response

Average time from exceedance detection to corrective action dropped from hours to minutes.
