Oil and gas

Refineries, terminals and stations, with reporting obligations on top.

What it solves

Detecting the leak is half of it. The other half is proving when it was detected, what was done, and how much was not emitted.

What gets measured here

Every signal, with the standard behind it

  • 500 ppm

    Defines a leak · 10,000 under some rules

    Fuga de volátiles

    What counts as a leak and how it's verified, so the finding is reportable.

    EPA Method 21

  • ≤ 15 d

    Final repair · first attempt ≤ 5 d

    Programa de reparación

    Survey frequency, repair deadline and follow-up verification, dated at every step.

    40 CFR 60 OOOOa

  • 4 levels

    Maximum working · high · high-high · overflow

    Sobrellenado de tanque

    Alarm and action levels, with the required response time for each.

    API 2350

  • 15 °C

    Standard volume · GSV = GOV × VCF

    Volumen corregido

    Volume is temperature-corrected before it becomes inventory. Without that, the number changes with the sun.

    API MPMS 11.1

The full catalogue is 311 standards across fourteen domains, and it lives inside the platform — next to the field where the number goes — not in an appendix to the manual.

What it uses

With the source cited

Every exposure limit carries its standard. The ones without are flagged as unverified rather than affecting rigour.
