Hazardous Liquid Pipelines — Computational Pipeline Monitoring.
Title 49, Code of Federal Regulations, Part 195 (the federal hazardous-liquid pipeline safety standard) requires operators of certain category-1 lines to install and continuously operate a CPM system meeting API 1130. Endpoint Integrity is a CPM system, and below maps the specific subsections Endpoint Integrity addresses.
Installation
CPM equipment must be installed on each new or replaced hazardous-liquid line. Endpoint Integrity provides the field hardware (EI Sentinel) + the cloud algorithm.
CPM operation
Operators must operate a CPM that complies with API 1130. Endpoint Integrity implements the algorithm class, alarm scheme, performance test, and record-keeping requirements.
Integrity management
Continuous monitoring on Could-Affect-High-Consequence-Area segments. EI's per-segment models monitor each line independently.
Reportable accident
Defines what triggers a 30-day-incident report. Faster detection narrows the release magnitude — reducing the chance the event crosses reporting thresholds.
Computational Pipeline Monitoring for Liquid Pipelines.
API 1130 (current edition) is the industry-recognized standard for CPM design, operation, maintenance, and testing. Endpoint Integrity's design satisfies the five primary obligations the standard places on a CPM system.
- Algorithm description. Endpoint Integrity publishes the EI Combined v3 architecture for operator inclusion in the integrity management plan.
- Alarm management. Per-segment ML threshold + suppression of operational transients (pump start, valve open, pig launch).
- Performance testing. Synthetic-leak injection trace + verified model response on demand for periodic test record.
- Maintenance procedures. Documented retrain cadence, model version control, rollback on regression.
- Operator interface. Pipeline map, alert history, magnitude/duration/location for each event, full audit log.
- Configuration controls. Role-based access, full audit log of threshold changes with operator + timestamp + CSV export.
Leak Detection Program Management.
API RP 1175 is the recommended practice for the management lifecycle of a pipeline leak detection program (PLDP) — the management-system framework PHMSA expects to see in an integrity management audit. Endpoint Integrity produces the operator-facing artifacts each element of the PLDP requires.
Strategy & goals
Endpoint Integrity provides per-pipeline detection-objective tracking (false-alarm rate target, MTTR target, performance test pass-rate).
Methods & technology
CPM with cross-stream ML is a documented methodology category. EI's Algorithm Description is available for operator integrity-management plans.
Performance management
Endpoint Integrity retains every alert + acknowledgement + response record. Pull a per-quarter accuracy report from the dashboard for the audit binder.
Training & competency
Operator training records and dashboard role-based access mapped to your competency matrix.
PIPES Act of 2020 — leak detection requirements extended to gas pipelines.
The Protecting Our Infrastructure of Pipelines and Enhancing Safety (PIPES) Act of 2020 directed PHMSA to issue final rules extending leak detection and repair requirements to additional categories of natural gas gathering and transmission lines (49 CFR Parts 191/192).
Endpoint Integrity's pressure-based detection is fundamentally product-agnostic: the cross-stream ML and the NPW localization apply identically to gas, NGL, crude, and refined-products lines. A single platform satisfies CFR Part 195 (hazardous liquid) and CFR Part 192 (natural gas) leak-detection obligations for an operator with mixed-product mileage.
Where the federal floor isn't the ceiling.
Several state regulators and most major pipeline insurers impose detection requirements above the federal minimum. Endpoint Integrity addresses these directly.
- Texas RRC §3.107 — pressure testing + abnormal operating condition response. Full event audit log.
- California OSFM — leak detection plan submission for hazardous liquid lines. Endpoint Integrity provides the methodology section.
- New York 16 NYCRR Part 754 — integrity management for hazardous liquid lines. Per-segment monitoring + alert retention.
- Insurance underwriter premium credits — operators have received documented premium reductions for documented sub-minute detection.
- OSHA PSM (29 CFR 1910.119) — for terminals + facilities adjacent to monitored pipeline. Alert routing into existing OSHA emergency-response protocols.
- Insurance reportability windows — faster detection narrows the release magnitude and may keep an event below reporter-required thresholds.
