Disposal Well Classes in Alberta, and Why They Matter at the Gate

I have spent eleven years reading Canadian energy regulation and trying to explain it to people who have to comply with it. Alberta is a good place to do that, because the framework is detailed, publicly available and revised often enough that keeping up is a real job rather than a formality.
My half of this site is the regulatory material: what the directives require, how licensing and approvals work, what the reporting obligations are, and where the framework has changed. I also edit everything Dale writes, mainly to check that a description of what operators do has not quietly become a statement about what is permitted.
The discipline I try to hold to is sourcing. If a page here says something is required, it should say which directive that comes from, so a reader can go and check the current version. Summaries go stale. A pointer to the source does not.
That is also why every regulatory page on this site carries a note telling you to verify before you act. It is not covering ourselves. It is that I have watched people make decisions from a copy of a directive saved on a shared drive four revisions ago, and it goes badly.
I am not a lawyer and nothing here is legal or compliance advice. For a compliance decision, talk to the AER or to counsel.

What the well classes mean, what each may legally receive, and why the class printed on a facility's approval decides whether your load gets taken.
Which directives apply to what, how the paperwork chain works from manifest to injection record, and where operators most often come unstuck.
Approval class, what they will actually accept, turnaround, how rejections are handled, and the documentation you should expect back with every load.
