When the KPSC tower is closed

The tower is staffed 0600-2200. Outside those hours Tri Cities Airport has no operating control tower: it becomes a self announce field on 135.3, and separation from other traffic is yours, not a controller's. Report your position and intentions on entry and on each leg of the pattern.

Runway lighting is often pilot controlled once the tower closes — check the KPSC airport page for the click sequence, and what to say on the radio.

Before taxi Tri-Cities

ATIS 125.65
A recorded loop of the field's weather, active runway and any notices, updated hourly or whenever conditions change. Listen before your first call, and tell the controller which letter you have so they do not read it to you again.
Clearance 120.0
Clearance delivery issues your IFR clearance, and at busier fields your VFR departure instructions and squawk code. Call before you request taxi, with the ATIS letter and your intended direction of flight.

Taxi & takeoff Tri-Cities

Ground 121.8
Ground control owns every taxiway and inactive runway on the field. Call for taxi with your position and destination on the field. You need an explicit clearance to cross any runway, including one that is not in use.
Tower 135.3
Tower owns the active runways and the surrounding surface area. Call before entering the surface area inbound, and hold short until you are cleared to take off or to cross.

Departure & arrival Spokane

App/Dep 128.75 (NORTH & WEST · initial contact), 133.15 (EAST & SOUTH)
One radar controller working both arrivals and departures — normal at a smaller TRACON. The same frequency takes your climb out and your inbound call.

Also

CTAF 135.3
The common frequency pilots use to announce themselves to each other at a field with no operating control tower. Nobody is controlling traffic — you are self announcing. Report your position and intentions on entry and on each leg of the pattern, and listen well before you transmit.
UNICOM 122.95
A ground station run by the FBO rather than the FAA, for fuel, parking and airport services. Use it for services. Where the field has no separate CTAF, the same frequency doubles as the advisory frequency.
Flight service 132.6 (LOW)
Flight Service handles briefings, flight plans and en route advisories, reached here through a remote outlet. Open and close VFR flight plans, and get updated weather in the air. 1-800-WX-BRIEF reaches the same specialists from the ground.
