The fumes emitting from the asphalt plant have been extraordinarily strong today. It was difficult for me to walk from my car to inside our building without being physically affected by those fumes. I also learned later that my maintenance team had no choice, but to turn off the air conditioning system, because the fumes from the outside were so strong that they were affecting students and those inside the building.
