On May 6, 2026, NOM-022-ASEA-2026 was published in the Official Gazette of the Federation, which establishes new requirements for industrial safety, operational and environmental protection for facilities for the production of cement and ready-mix concrete:
- Natural gas compression (CNG)
- Loading of transportable storage modules (MAT)
- CNG refueling stations for automotive vehicles
What changes?
- NOM-010-ASEA-2016 is replaced.
- Technical and safety standards are updated
- International best practices are incorporated
- Reinforced design, operation and maintenance requirements
Entry into force
The NOM will become effective 180 calendar days after its publication.
From that moment on:
- NOM-010-ASEA-2016 is formally cancelled.
- Implementation of the new regulatory framework begins
Transitional regime
The NOM establishes a differentiated scheme according to the type and condition of the facilities:
Existing facilities in operation
- The Design (5) and Construction (6) chapters do not apply to them as long as the original design is not modified.
- They will have 90 calendar days from the effective date to comply with the Operation and Maintenance obligations (Chapter 7).
2. Projects under construction
- If they already have a design approval:
- May continue under NOM-010-ASEA-2016 in design and construction.
- Provided there are no modifications to the original design
- The new NOM will apply mainly in later stages
3. Previous opinions
- The opinions issued under NOM-010-ASEA-2016 will remain valid until their validity expires.
4. Relevant changes in compliance
- For certain facilities (type B3), the operating report will no longer be annual but every 5 years, subject to future regulation.
What should companies do?
Recommended:
- Identify which obligations are immediate vs. deferred
- Perform a compliance diagnosis (gap analysis)
- Plan technical adjustments and budget
- Review facilities and security protocols
