Just remember that if departing an uncontrolled field when you can not maintain your own terrain separation and absent of any other clearance by ATC you must follow the ODP published on the back of the JEPP plate on the bottom box for the specific runway. Otherwise you must tell ATC that you can MAINTAIN YOUR OWN TERRAIN SEPARATION. Por ejemplo, try departing EGE or ASE by climbing to 400' and then turning on course maintaining a 3.3 degree climb gradient. In the real world we look at several different factors when it is IMC or night.

One-Engine-Inoperative Departure procedure-Aircraft Performance Group provides this data if required for that airport. *This will give you a non standard route to save your bacon if you bag a blower on departure*.
(I ALWAYS have this one in the back of my mind just incase)

OR climb to 400' then proceed on course if their is no published ODP

Follow these steps at any airport and you will be safe. KC-10 is right that if non standard climb gradients are published for a SID and you are CLEARED via that SID then you must adhere to climb gradient or get a waiver from ATC regardless of whether it is for terrain, noise abatement or traffic.

Steel is also correct that if Tower is "home" you will not be doing a DP. You will either be cleared via a SID or given a heading to fly after takeoff to be funneled into the system. ODP=Uncontrolled field
