School Board Minutes
Red Rock Central District
No. 2884
Monday, March 3, 2008
A Special Meeting of the Board of Education,
District #2884, was held in the Lamberton Board Room on Monday, March 3, 2008,
beginning at 6:00 p.m. Members present
were: Clarke, Derickson, Kelsey, Moldan,
Myers, Rogotzke, and Westerman.
Superintendent Brennan, Principal Olson, Christine Schmidt, A.J. Yadav,
Giles Riley, Joe Dietl, and Denise Clarke were also in attendance.
Superintendent Brennan opened by introducing the
special guests for the meeting – Dr. Rita Messing and Mr. Dale Dorschner of the
Minnesota Department of Health.
Superintendent Brennan went on to give a brief
description of the mercury issue in the Lamberton gymnasium. He explained that a representative of
Minnesota Pollution Control had found amounts of mercury in the science labs
and mercury vapors in the gymnasium.
Dr. Messing explained that there are 3 ways for
mercury to get into ones systems – those being 1) breathing in the vapors; 2)
eating fish with mercury content; and 3) swallowing an amount of liquid
mercury.
The mercury vapor readings in our gym are 1200 nanograms/cubic
meter, while anything below 800 ng/m3 is
acceptable. Although a reading of 1200
is not a number to get extremely concerned about, it does need to be
checked. Both Dr. Messing and Mr.
Dorschner agreed that increasing ventilation in the gym should bring the
mercury levels down to below 800. They
recommended that the District 1) do future monitoring; 2) ventilate; 3)
evaluate the cost over a period of years; and 4) evaluate occupational exposure
over the years.
It was also recommended that Superintendent Brennan
and the Pollution Control Agency create a plan of ventilation and follow up
with a fall reading. If this is working,
that’s all that will need to be done.
The meeting was declared adjourned by Chairman
Derickson at 6:30 p.m.
