deblasiocuomoState and city officials will develop a package of regulations aimed at combating Legionnaires’ disease, Gov. Andrew Cuomo and Mayor Bill de Blasio announced on Tuesday afternoon in a joint statement.

The regulations will include required time frames and steps for the maintenance and testing of cooling towers, fines for not cpmplying with the regulations and a statewide registry.

The statement — released by the offices of both Cuomo and de Blasio — come after 12 people have died and more than 100 left sickened by an outbreak of Legionnaires’ disease in the Bronx.

The statement described the regulations — the details of which remain vague at best — also comes after both the mayor and the governor have been seemingly stepping on each others’ toes to respond to the outbreak.

Officials hailed the move as a “unprecedented step” to combat the outbreak.

“An unprecedented event like this outbreak of Legionnaires’ disease in the South Bronx requires an unprecedented response,” de Blasio. “This legislative action will be the first of its kind for a major American city, as well as the first set of regulations by any state in the union, and it will establish new registration, cleaning and monitoring standards for cooling towers in the fight against Legionnaires’ disease. As the current outbreak tapers off, we now look to how to prevent these outbreaks in the future, and this groundbreaking legislation provides the tools needed to safeguard our communities. The Mayor’s Office continues to work in coordination with the City Council, as well as with our state and federal partners, to keep our people safe and protect public health.”

Both Cuomo and de Blasio released conflicting information at separate news conferences on Monday, a development that only added to the speculation that both men continue their behind-the-scenes political squabble that spilled out into public view this week.

The governor, who some saw as bigfooting the mayor on the Legionnaires’ outbreak last week, stressed on Tuesday there was a “unified” approach.

“Protecting the public health is our number one priority,” Cuomo said in the statement. “I want the people of New York to know that we are doing everything necessary to tackle this outbreak and stop it from happening again. This unified approach will help in this effort, and I want to thank the City for working hand-in-hand on these emergency regulations to prevent the occurrence of Legionnaires’ disease in the future.”

The regulations will be written by officials at the city and state level, and the City Council is expected to approve them.

The state Legislature will not need to convene in Albany to approve the regulations; Cuomo is expected to use his own emergency powers to enact them on the state level.
