Privateer01 is absolutely correct, all commercial operators who hold an AOC have them right down to the single pilot,single aircraft operator.
There are many pages that generally restate conditions/requirements already in the FARs and others that impose stricter conditions. This is because the FARs are far less restrictive and complex than the CAOs, CARs & AIP here in Australia.
Alternate requirements are a classic example, the FARs have 1-2 paragraphs that basically cover weather parameters only so the OPSPECS for commercial operators cover navaid requirements that here in Aust are already covered in the AIP.
Here in Aust due to our complex and somewhat onerous rules and regs the OPSPECS should not significantly add to an operators already existing compliance requirements.
Each OPSPEC page has to be signed by the issuing inspector and the operator.
However if the operator disagrees with the issuance of an OPSPEC and refuses to sign and comply but it is deemed mandatory for the operators AOC then he wont have a choice.
As Chimbu said though the contents are not open to" interpretation" by individual inspectors, nor are they written in legalese, well at least not in the US.
