Well, each operator must make and follow and operations manual, and this is the governing document for that operator. However, that manual shall be in compliance with national regulations, which in most cases happen to be EU-OPS. Note however that EU-OPS in itself is not automatically law, it has to be made into law by each member country, thus allowing for national variations/exceptions/interpretations. I've been told this is not the case with the coming EASA OPS.
By googling I found this
document. Use the search function to find "Subpart Q" and you will find it. I'm not sure it's updated, though.
I hope that's a bit less vague!
