How to maintain everything in tablespace APPS_TS_INTERFACE

 Hi,

I would like to know how to maintain table/index in tablespace APPS_TS_INTERFACE.

Because at this time the growth for this tablespace is quite fast.

I need to know if it is possible and safe  to delete the data/index in this tablespace ?
