Protocols for proactive Federal response are most likely to be implemented for catastrophic events involving chemical, biological, radiological, nuclear, or high-yield explosive weapons of mass destruction, or large magnitude earthquakes or other natural or technological disasters in or near heavily populated areas.
Guiding principles for proactive Federal response include the following:
- The primary mission is to save lives; protect critical infrastructure, property, and the environment; contain the event; and preserve national security.
- Standard procedures regarding requests for assistance may be expedited or, under extreme circumstances, suspended in the immediate aftermath of an event of catastrophic magnitude.
- Identified Federal response resources will deploy and begin necessary operations as required to commence life-safety activities.
- Notification and full coordination with States will occur, but the coordination process must not delay or impede the rapid deployment and use of critical resources. States are urged to notify and coordinate with local governments regarding a proactive Federal response.
- State and local governments are encouraged to conduct collaborative planning with the Federal Government as a part of "steady-state" preparedness for catastrophic incidents.

All that says is the relief requestor doesn't have to necessarily follow the standard procedure (which is forms, letters, copies to certain agencies, and so on and so forth as the bureacracy goes) for making the request. E.g., a phone call might be enough in certain circumstances.
Waiving the assistance requestor's duty to follow standard procedure does not suppoert the assertion "that DHS had the authority to roll FEMA into this on its own accord."
