Can any one tell me a bit about what the test determines and how those
determinations effect building permits. Many thanks.

This test determines how quickly the soil on your lot absorbs water. This
determines the type and location of a septic system.

Thanks very much.
Assuming 'soil' failed the perc test, is there a way to modify the area
to 'pass' a test. That is, with a different septic tank or leach system?
Does that effect the type of 'grades' a perc test would have to have in
order to pass? Thanks again.

There may be alternate septic designs that can pass local review. You
will need to contact a local septic system designer to discuss your
options.

As I understand it, the test neither passes nor fails. It only determines
what type of soil there is and whether or not the soil is suitable for a
particular type of septic system.
Once tested, take the results to your county engineers office and let them
decide which is best.

Around here they scoop out a 40' by 60' by 4' deep area and fill it with
bank run gravel.

Many thanks for the great responses.
In my hillside neighborhood we have about 24 homes. The average size is
1800 - 2200 sq. ft and we have a ranch style community in a remote area
serviced by one steep (23% grade measured in one area) and decaying
road. A new 'lot' owner is trying to build a 4400 sq ft behemoth with
four baths. The whole neighborhood is against such an incongruous home
and also the damage that will be done to the hillside. It's shear where
they intend to build which requires thousands of tons of cement for the
caissons, etc... not good. I was wondering if a 'perc' test failure
might derail this large a (or any?) home build... thanks again.

No. There are septic systems which can be engineered for ANY
terrain. A failed perc test will just rule out a standard
tank and drain field type septic system.

I did the preliminary perc test on my property in TN. Then the soil
scientist came out and confirmed the result and wrote a report the I
have to take to the local DEQ office and pay money to get a permit to
build the septic system.
Basically, I dug 6 holes where the soil scientist told me. The holes
are 3' deep and about 6" in diameter. this took all day with a post
hole digger. I'd rent a power auger if I had to do it again. They
were filled with water and the next day the water level is marked with
a nail in the side of the hole. Then a known amount of water is poured
in and the timer started. You want to know how many gallons per minute
the soil is absorbing by seeing how long it takes the water level to
get to the nail. The absorption rate of the soil will determine if and
what size of septic field you'll be required to have to satisfy the DEQ
people. The rules are getting tougher. They don't want the water to
run through too fast like in sand, but not to slow like in hard clay in
TN. I think this pretty well summarizes my experience. Bottom line
is, once you get a septic system take good care of it, cause it's a big
deal to do another one. Good luck.
