Unless you are operating an other than complex aircraft non-commercially (NCO), all CAT, NCC and SPO operations (will) require the instruments and equipment required for the intended flight to be serviceable unless alleviated in accordance with the operators MEL/CDL or equivalent document, or under the terms of a permit to fly.
FD is correct, these docs form part of the OM, but may exist as a separate manual or electronic document.
Note the legal obligation to comply with the MEL/CDL is set out in 965-2012, as amended. Putting it in your OM is but one means of compliance. You may elect to do otherwise and this would require the approval of your member state authority.
