scope:

General

This Document provides recommendations and guidance on preparing and maintaining measurement, monitoring, and verification plans for the geological storage of CO₂ streams in accordance with CSA Z741, regardless of whether the project is located onshore or offshore. While not intended for storage associated with enhanced oil recovery using CO₂ injection, the Technical Specification could be useful for those projects.

Inclusions

In addition to CSA Z741, this Document may be applicable for use with ISO 27914. This Document is applicable to projects that are located in onshore or offshore environments.

Exclusions

This Document is not meant to apply to the storage of CO₂ associated with CO₂-EOR. However, as shown by Annex B, the use of MMV plans might be required by regulators and therefore this Document may be used by project proponents, regulators, and interested parties in those situations.

Terminology

In this Document, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Document; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Document.
