Urgent requests still require some sort of analysis to justify them. The applicant also has to show either that they will not create problems for others, or that they have coordinated with potentially affected parties and all agree to accept whatever interference results. The example filing I have been citing from WUSA, Washington, DC, included an interference agreement between them and two other stations. The agreement was easily reached because all parties realized that the level of interference was way overstated (cash also helps.)

This is a rare, but not unique, situation in broadcast allocation management. Prior to the mid 60s, the rules for FM allocations in the US produced stations too close together for the ERPs used.
