Attique Ahmad owned the Spin$-$N$-$Market, a convenience store and gas station. The... gas pumps were fed by underground tanks, one of which had a leak at its top that allowed water to enter. Ahmad emptied the tank by pumping its contents into a storm drain and a sewer system. Through the storm drain, gasoline flowed into a creek, forcing the city to clean the water. Through the sewer system, gasoline flowed into a sewage treatment plant, forcing the city to evacuate the plant and two nearby schools. Ahmed was charged with discharging a pollutant without a permit, which is a criminal violation of the Clean Water Act. The act provides that a person who $$knowingly violates$$ the act commits a felony. Ahmad claimed that he had believed he was discharging only water. Did Ahmad commit a felony? Why or why not?
