Section 304 defines the right to subsidize oil companies if the cost of supply goes up. It also allows them to create loan guarantees of any size to prop up a favored industry or business.
Section 308 gives the right to the government to install THEIR OWN equipment in a private facility and to expand it and determine the operating procedure for that facility that the government deems to be in the best interest of preserving a critical resource.
The government could basically take over any private industry or sector under this order for the purposes of national defense whether we are in a state of emergency OR NOT.
