The ANO is not defunct, the CAA uses JAR-OPS1 as a measure to ascertain whether or not to grant an AOC under the terms of Article 6 of the current ANO.( see page 1 of the AOC) You will need to obtain a copy of the current AOC to ascertain precisely which requirements of JAR-OPS1 that Easy' have to comply with.(These have in the past been contained in the Second Schedule to an AOC and referred to in General Condition A6) Apologies for all the "currents" but the up-to-date versions must be used!
