difference among engineering fill, select fill, structural fill, and general fill?
(OP)
1. can anyone explain to me the difference among engineering fill, select fill, structural fill, and general fill?
2. And for a berm of a dry detention pond, what type of fill is appropriate and material type - sand, clay, silt, or in terms of PI?
3. For backfill of a storm sewer pipe under concrete roadway, what type of fill is appropriate?
Thanks.

Those are very general questions with no specific site details given. So, if any answers, they will be general maybe. If specific, do they apply to your site or job? In defining various fill types, usually the job specs or local codes will do the defining. What's suitable in one area may not even be available in another.

"General fill" can mean anything.
Further, unless each term is defined by the specifications, they also mean little as OG noted, they are too broad to be of much use.
As for which materials are appropriate for certain applications....that will depend on a lot of site and area specific issues and practices. Since we don't have any additional information on your location or application other than the general statements, we can't offer much.

But your best bet is probably to ask the designer what he had in mind.
Oldestguy, I've seen advertisements for "DOT-approved Item 4" even though our DOT stopped using that item number for road subbase decades ago.

So, to me, all these terms are not strictly defined, one person's select fill could be another one's engineering fill, or structural fill.

Select fill - I've selected something that meets my engineering objectives, which may be the best of what's available - i.e., I'll take all the fat clay as long as the PI is less than 25 and there's at least 35 percent sand content. In this case, that may be select enough to support the 3H:1V slopes.
Structural fill - I've specified the minimum requirements for earthwork when the earthwork supports a structure (or the soil structure interaction requires some engineering performance - i.e., adjacent to a laterally-loaded pile)
General fill - so, the topsoil has to go somewhere, eh?
