Narrative:

Air carrier X departed rno IFR; was turned left direct llc; leveled at 120. Air carrier Y inbound to rno; IFR; level at 130. Air carrier X was issued as traffic to air carrier Y. Air carrier Y reported air carrier X in sight. Air carrier Y was issued as traffic to air carrier X. Air carrier X reported air carrier Y in sight. Air carrier X was instructed to maintain visual separation with the traffic; pilot's discretion; climb and maintain FL190. Air carrier X acknowledged the instructions and started his climb. Air carrier Y was told that air carrier X was maintaining visual separation and continuing his climb. Air carrier Y acknowledged. Air carrier Y then advised that he was responding to an RA and climbing. Air carrier X keyed up and told air carrier Y that he was sorry for causing his RA. I later learned that air carrier X also responded to an RA. Air carrier X continued to his destination and air carrier Y landed at rno. Recommendation; I feel that I followed the rules of the book to the letter. I thought that air carrier X would use better judgment and wait until he was past air carrier Y to start his climb. In the future; I will use more diligence to ensure that this does not happen again. In the future; I will just wait until the aircraft have passed; then continue their descent and/or climb.
