You can certainly go this route, as I'm sure people have created specific DR policies on this forum but this is typically covered in a Contingency Planning Policy, which encompasses BC and DR plans. Along with many other types of plans, e.g., Cybersecurity Incident Response Plans, Crisis Communications Plans, etc.
NIST 800-34, Rev 1 Contingency Planning Guide for Federal Information Systems
Tagging @CISOScott because he has extensive experience in Government work. Some things to include if I were to create a specific DR policy in no particular order:
- Roles and responsibilities
- Specific disasters that will be included in the DRP
- Defining recovery time objectives (Or at least say it's going to be included in the DR plan)
- BIA requirements
- Communication plan or point to one that's already created
There's more but others can chime in with their thoughts.
