Narrative:

This sector; 44; had been saturated with IFR arrivals to trk; along with IFR departures; VFR to IFR pop ups and VFR flight following requests all associated with trk airport. The entire training session was far more complex than what the sector can handle. I was an on the job training instructor (ojti) at the time; training a developmental controller on the position. After an hour on position and numerous stressors along with complex traffic volume/saturation; the situation in question occurred. Aircraft X; VFR popped up 15 east of hnw VOR requesting IFR. At the time; my trainee was just recovering from over 8 IFR arrivals into a temporary towered airport. Aircraft X was given an IFR clearance below the minimum IFR altitude (mia)/MVA. Although later confirmed that the pilot/aircraft had terrain in sight; we still failed to notice that the slow climbing pc-12 was below the mia/MVA. Most of the aircraft into and out of trk during this session had been CL30 or glf high performing jets. We should not have been training during this period; no matter how great the training experience could have been; safety was compromised.I advise this event be reviewed in its entirety. The volume; complexity; and convoluted nature of a temporary tower at trk and the inability of northern california TRACON (nct) to space or sequence for an arrival push is not only dangerous but [also] unacceptable. Although we do not have this consistent amount of volume on any given day; I still do believe that we should be trained better; or be more prepared for such a situation. Throughout my time here at ZOA; sector 44 has been a nightmare of a sector; ever-changing procedures; and patters; temporary towers and airspace changes and lack of proper training in regards to trk temporary tower. We should have no been training during this period.I suggest that we give nct the airspace between silver nugget and paradise buttes regardless of the issues this may cause without facility rating or level. Safety is our main concern.

Title: ZOA ARTCC Controller reported that while conducting training during a high volume; and complex period; a VFR pop-up was issued an IFR clearance below the MVA.

Narrative: This sector; 44; had been saturated with IFR arrivals to TRK; along with IFR departures; VFR to IFR pop ups and VFR flight following requests all associated with TRK airport. The entire training session was far more complex than what the sector can handle. I was an On the Job Training Instructor (OJTI) at the time; training a Developmental Controller on the position. After an hour on position and numerous stressors along with complex traffic volume/saturation; the situation in question occurred. Aircraft X; VFR popped up 15 EAST of HNW VOR requesting IFR. At the time; my Trainee was just recovering from over 8 IFR arrivals into a temporary towered airport. Aircraft X was given an IFR clearance below the Minimum IFR Altitude (MIA)/MVA. Although later confirmed that the pilot/aircraft had terrain in sight; we still failed to notice that the slow climbing PC-12 was below the MIA/MVA. Most of the aircraft into and out of TRK during this session had been CL30 or GLF high performing jets. WE SHOULD NOT HAVE BEEN TRAINING DURING THIS PERIOD; no matter how great the training experience could have been; safety was compromised.I advise this event be reviewed in its entirety. The volume; complexity; and convoluted nature of a temporary tower at TRK and the inability of Northern California TRACON (NCT) to space or sequence for an arrival push is not only dangerous but [also] unacceptable. Although we do not have this consistent amount of volume on any given day; I still do believe that we should be trained better; or be more prepared for such a situation. Throughout my time here at ZOA; Sector 44 has been a nightmare of a sector; ever-changing procedures; and patters; temporary towers and airspace changes and lack of proper training in regards to TRK TEMPORARY TOWER. WE SHOULD HAVE NO BEEN TRAINING DURING THIS PERIOD.I suggest that we give NCT the airspace between SILVER NUGGET and PARADISE BUTTES regardless of the issues this may cause without facility rating or level. SAFETY is our main concern.
