Seal or cover a septic tank lid

Is it safe to tightly seal (or cover) the lid to the "pump tank" in my septic system?

I have a two tank septic system. The first tank is the main septic tank, which then drains to a pump tank. Once enough water has accumulated in the pump tank, the liquid is pumped uphill to the leach field.
The pump tank is new and has a plastic lid that isn't quite air tight. Because of this, it occasionally smells around the tank.
Is it safe to completely cover the tank lid with dirt, or perhaps seal the lid with caulk?
