People who don't live in the East Riding are being asked not to visit the household waste recycling site at Airmyn, near Goole - or they will be turned away.
East Riding of Yorkshire Council introduced passes on October 1, allowing residents entry to all of the area's household waste recycling sites, in order to make the system fairer for people living in the East Riding.
But since then staff at the Airmyn site have had to turn away a handful of people not living in the East Riding, with some becoming abusive towards them.
The problem has only happened at the Airmyn site.
Paul Tripp, head of streetscene services at the council, said: "We won't tolerate this type of behaviour.
"The site staff have had to deal with a small number of people who became abusive when they were turned away.
"But be clear, if people don't live in the East Riding they shouldn't be using our sites, so we are asking them to please stay away.
"We have had no issues with East Riding residents. They understand why we've had to introduce the passes and they are always welcome, as long as they show their passes or proof of address."
Residents living in the East Riding were all sent their free passes in the post this summer by the council.
The passes can be used to gain entry to any of the council's 10 household waste recycling sites.
Alternatively, a valid driving licence, utility bill, council tax bill or bank statement showing the person's address can be used to prove that person lives at an East Riding address.
Other authorities, including Hull City Council, already run a pass entry system at their sites.
East Riding of Yorkshire Council won't replace any passes through loss or damage. If a resident misplaces their pass, they can use the alternatives instead.
All passes will be renewed just before the expiry date of December 2022.
