The conduct of a sanctioned event shall be in strict compliance with applicable USMS swimming rules and administrative regulations, or when the sanctioned event is held simultaneously in conjunction with a USA Swimming sanctioned meet, with applicable USA Swimming rules and administrative regulations.”
The phrase “applicable rules and administrative regulations” is covered in part by the current dual sanction agreement between USA Swimming and USMS dated December 2014 (included as Appendix B of the USMS R ule Book). This agreement defines a “combined meet” as USMS and USA -Swimming athletes swimming in the same heats without specific lanes being allocated for each organization. A combined meet may be sanctioned by both USA Swimming and USMS and all swimmers “competing according to USA- Swimming rules”.
