A person who violates this chapter or Chapter 191, Natural Resources Code, is subject to a civil penalty of not less than $50 nor more than $1,000 for each day of violation. Each day a violation continues may be considered a separate violation. If the party seeking a civil penalty demonstrates the same violation occurred on more than one day, it is presumed that the person committed a violation on each intervening day between the days of violation, including the days on which a violation was demonstrated.
