OPS vehicle called local control (training in progress) to request to go into the RSA to sweep up some glass from a broken light.  He said he would be on the asphalt but clear of the runway by taxiway Juliet.  This was established between several transmissions. OPS confirmed more than once he would be clear of the runway. At no time did he mention or did we approve him to cross runway 8/26. Air carrier was informed of the men and vehicle on the west side of the runway. OPS then proceeded to cross the runway to the north side without permission.  Before local could key up to tell air carrier to go around they were telling local they were going around on their own due to the vehicle. OPS then called local to try and confirm what he was approved to do.  He was already across the runway and on the north side which is not by any taxiway like he originally stated. We could have been a little clearer on communications with the OPS vehicle about what he wanted to do.  Even then though; we cannot read his mind that he needed to cross the runway.  So if he never would have mentioned this to us we wouldn't know.
Aircraft X on final for RWY 26 when OPS vehicle called Local for coordination. OPS requested to sweep glass from a broken runway edge light and stated that they would be on the pavement but at no time across the runway edge line infringing onto the runway.  At no point in time during OPS request did they mention crossing runway 26 and OPS was instructed to hold short of the runway at all times.  There was some confusion apparently because OPS really wanted to sweep glass across and down the runway and needed to cross in doing so.  This was not requested to Local control and OPS was told to proceed with their operations. OPS turned out onto taxiway J and then proceeded to cross runway 26 while Aircraft X was on short final. Aircraft X was re-sequenced by Local and landed without incident.Recommendation is that OPS be fully aware if a runway crossing is granted or denied by Local/Tower.
