Interesting find Taildragger.
LOC IAD does not have an ESV associated with the facility except for the DME. The DME ESV is out to 19nm between 3,000 and 4,800'
According to this information it would not be correct for ATC to instruct you to intercept the LOC outside of the standard 18nm service volume. I'll have to ask one of the ATC'ers that I work with about it more on Monday or maybe a controller with local knowledge on the forum will provide some input.

LOC LAX is an example of a LOC that has numerous ESVs associated with the facility. The LOC has an ESV all the way out 85nm from 10,000-15,000'! There is another LOC and DME ESV at 42nm between those same altitudes and you'll see from the approach plate that procedurally they want to use LUVYN at no lower than 10,000' at 41DME off of the LOC. The GS also has an ESV that would encompass FUELR, though it shows it only at 8100 and it looks like the plate reads that you could be at 7,000 or above.
