Starting Wednesday, passengers traveling from the UK will receive a DOH Commissioner's Order to quarantine via certified mail.
Additionally, UK travelers will be personally served DOH Commissioner's Order to quarantine by the Sheriff's Office, and the Travel Unit will door knock to ensure compliance of these orders.
"This is going to be the busiest travel time of the year when you think about all these days, up through New Year's intensive travel time," de Blasio said. "We need people not to travel but if they do, we're going to be very, very stringent about the rules."
New compliance rules for international travelers visiting NYC
For those who don't comply, there will be a $1,000 fine per day of noncompliance.
"We are going to have sheriff's deputies go to the home or the hotel of every single traveler coming in from the UK," de Blasio said. "So when they arrive at the airport, they're going to have to fill out the form notifying us that they are coming into New York City. We're going to provide them with that commissioners order, but then there's going to be a follow up, direct home visit or hotel visit from the sheriff's deputy to confirm that they are following the quarantine, or if they are not, they will be penalized. We cannot take chances with anyone who travels particularly folks traveling in for the UK. So, to everyone. Look, if you don't comply with the quarantine. That's $1,000 fine. To begin, they want if you continue, not to comply with the quarantine is $1,000 for each additional day I want to really make sure we get this point across. You don't want to penalize people. Everyone's been through hell this year. We don't want to, but if you don't follow quarantine you're endangering everyone else in the city, right as we're fighting the second wave."
