Narrative:
Phl evening rush, landing runway 9R and 17 and departing runways 9L and 17. Traffic inbound to 9R at such tight intervals that local had to prompt each arrival to exit the runway quickly to avoid go around's. Constant line-up for departures on both runways. In departure delays for ZNY. Steady inbound traffic to runway 17. Local controller put small aircraft X in position on runway 17 for departure for traffic to depart 9L. Ground control became saturated. Local had to hold 6 aircraft on south side of runway 9L and coordinate with ground to get things moving. Local cleared atx Y to land on runway 17 and forgot about small aircraft X, being preoccupied with several close interval 9R arrs and holding aircraft for ground. On 1 mi final atx Y advised he was going around because an aircraft was on the runway. Local kept atx Y in left traffic for 17 and he landed behind the aircraft behind him on final after small aircraft X took off.

Title: SMA X HOLDING IN POSITION AWAITING TKOF CLRNC. ATX Y WAS CLEARED TO LAND. ATX Y EXECUTED A GO AROUND AT 1 MILE DUE TO SMA X IN POSITION. POSSIBLE LESS THAN STANDARD SEPARATION SYSTEM ERROR.
Narrative: PHL EVENING RUSH, LNDG RWY 9R AND 17 AND DEPARTING RWYS 9L AND 17. TFC INBND TO 9R AT SUCH TIGHT INTERVALS THAT LCL HAD TO PROMPT EACH ARR TO EXIT THE RWY QUICKLY TO AVOID GAR'S. CONSTANT LINE-UP FOR DEPS ON BOTH RWYS. IN DEP DELAYS FOR ZNY. STEADY INBND TFC TO RWY 17. LCL CTLR PUT SMA X IN POS ON RWY 17 FOR DEP FOR TFC TO DEPART 9L. GND CTL BECAME SATURATED. LCL HAD TO HOLD 6 ACFT ON S SIDE OF RWY 9L AND COORDINATE WITH GND TO GET THINGS MOVING. LCL CLRED ATX Y TO LAND ON RWY 17 AND FORGOT ABOUT SMA X, BEING PREOCCUPIED WITH SEVERAL CLOSE INTERVAL 9R ARRS AND HOLDING ACFT FOR GND. ON 1 MI FINAL ATX Y ADVISED HE WAS GOING AROUND BECAUSE AN ACFT WAS ON THE RWY. LCL KEPT ATX Y IN LEFT TFC FOR 17 AND HE LANDED BEHIND THE ACFT BEHIND HIM ON FINAL AFTER SMA X TOOK OFF.
