I'm currently trying to understand H.R.3684 - Infrastructure Investment and Jobs Act (IIJA) but there are a few things I don't understand:
- The price tag:
People are referring to the bill as the $1.2tn, $1tn & $950bn infrastructure package.
- What is the correct amount?
- What is the correct timeline (5yrs or 8yrs)
- Definition of "baseline spending":
Media talks about $550bn additional spending in several sectors.
- But what is the baseline they are referring to?
- Is it the 2021 funding level?
- Is it the 2021 authorization level?
- Does it differ for different sectors?
- Authorization vs. Appropriation
As far as I understand, authorization is some sort of legal foundation. If spending is discretionary (?) every year in budget negotiations, congress debates how much money they should appropriate to each program out of the amount authorized. However, in the current bill there are a Lot of additional appropriations in the last segment (Division J). So some programs, for example Northeast-Corridor Amtrak funding, gets appropriations for the full timespan (22-26) that are higher than the authorized spending in the specific segment of the bill.
- How can I interpret those numbers?
- Is it that those amounts appropriated in the appropriations segments are guaranteed spending and those numbers in the authorization segments are additional possible spending in each year?
Which would result in my last question:
- Does the price tag ($1.2tn/$950bn/$550bn) refer to appropriated (guaranteed) spending or does it refer to "possible" spending (appropriated + authorized to be appropriated) spending.
