BALTIMORE (WBFF) -- Governor Hogan is frustrated over the lack of air conditioning in city schools.

Just after the second day of school after soaring temperatures prompt school officials to send students and staff in buildings without AC to close 2 hours early yesterday.

The early dismissal only applied to schools without AC.

Still that meant that dozens of schools and their students lost class time on the second day of of the new school year.

This has been raising concern for many.

So when do schools without air-conditioning close early because of the heat?

When the temperature in the majority of classrooms in most buildings is 85 degrees or higher and students cannot be relocated to cooler areas or the outside heat index reaches 100 degrees by 10:30 a.m.

The district may also close individual schools if cooling systems not working properly.

When schools close early after-school programs and athletic events are canceled.

In a statement, Governor Larry Hogan says:

It is outrageous and completely unacceptable that the third-highest funded large school system in America still refuses to put air conditioning in their schools and had to send kids home from 57 hot school buildings. The Baltimore City School System must be held accountable and had to send kids home from 57 hot school buildings the Baltimore City School system must be held accountable.

Baltimore city schools developed a plan in January 2017 to ensure all buildings would be air-conditioned by the 2022-2023 school year.

The plan estimated to cost about 30 million dollars.
