OSHA is a Federal mandate. The NEC is typically a State mandate. Most other electrical standards including the 70E are "National Consensus Standards" that OSHA through the "General Duty Clause" encourage you to use. Therefore all the stuff in the 70E about who is responsible for enforcing it are just so much fancy talking.
If your company wants to exceed the OSHA and NEC requirements by adopting the 70E then the burden is on your company to enforce it. To enforce it through internal practice and to enforce it through contractual agreements with those they hire by requiring them to comply. If it's in the contractor's contract then it becomes binding for breaches in contract.
Having said that it's still a good idea to officially adopt and comply with the 70E for these reasons:
1) Obviously for safety's sake.
2) OSHA will want to know your policies for meeting their requirements. 70E adoption works as part of your policy. It's always a bad idea to tell OSHA that you're winging it.
3) Juries tend to agree with OSHA. A diligent attempt to meet the 70E is viewed a lot better than confessing you just play it by ear.
4) You might roll your own policy but let's face it, a lot more experts have reviewed the 70E than will ever view an in-house policy.
5) You might find contractor's that find it easy to comply since they try to anyway. What are the odds they know the details of your in-house policy.
