BUTLER TWP — The Butler School Board voted unanimously Monday night to adjust the school calendar — and reopen Summit Township Elementary School on Jan. 3.

During the move from Broad Street Elementary School back to Summit, the Summit pupils will take a field trip on Dec. 21 to the Intermediate High School. Dec. 22 and Jan. 2 will be school holidays for Summit students and they will be in class on Jan. 22 and Feb. 16, when the rest of the district is scheduled to have in-service days.

Teachers and district staff will move furniture and all classroom and building supplies during the holiday break.

The district did not need permission from the state Department of Education to move back into the building, though the department will be notified, Superintendent Brian White said.

The district must schedule a public hearing, likely for one of its meetings in January, and wait three months after the hearing before voting to officially close Broad Street, solicitor Tom King said.

Summit Township Elementary School has been closed since January after the school board learned that the district administrators had not take action to correct issues with the building's well water that were revealed by water tests in August of 2016. Subsequent testing showed that the building's water contained lead and copper concentrations well above the action levels set by the Environmental Protection Agency and state Department of Environmental Protection.

Former superintendent Dr. Dale Lumley, former assistant superintendent Mary Wolf and former maintenance supervisor Glenn Terwilliger all resigned or retired from their positions after the district's delayed response to the situation became public.

A new public water line was installed and connected in August and water fixtures in the school were recently replaced.

Several rounds of recent water tests have shown that the water in the building no longer contains dangerous levels of lead and copper, though officials are continuing to do tests and monitor the water.
