Selecting a transistor - Reading transistor datasheets
The saturation curves are for switching applications, so you can ignore those numbers if you are indeed operating in the linear region, say with Vce >= 1.0V. If what you wrote is incorrect, and it's not in the linear region, then all the below is garbage. 

hFE is stated to be a minimum of 100 at 10mA and at 100mA (and 25°C). Those are firm guarantees. There is no maximum hFE given. This transistor won't be the best to use if your circuit is heavily dependent on the value of hFE- it's more specified for switching applications. 

We can, however, make some guesses. From the typical curves (Fig 5), the gain at 30mA in the linear region is between 90 and 270 or so, depending on temperature, with it typically at about 210 at 25°C. Since the gain can be as low as 100 at 25°C, it may be reasonable to guess that the gain at -55°C can be as low as (100/210)* 90 = 42. Similarly, we might guess (by risky extrapolation) it could be as high as perhaps 450 at 150°C. We might want to allow for a bit more than that on both sides, since we're extrapolating so maybe 40 to 500, at 30mA collector current, over the full temperature range of -55 to 150°C. You can judge how much safety margin to add on those numbers. 

With a 10:1 or more range in hFE you'll have to use something like emitter degeneration to properly bias the transistor in the linear range. Below 1V Vce the hFE will drop as the transistor saturates. 



Note you can buy 'binned' transistors with a better controlled and characterized hFE but even with that the variation between parts may still be 2:1 before temperature is taken into account (eg. 120~240 hFE).
