The commissioners court must issue written findings stating the reasons why compliance is impractical.

(d) A delay or a variance granted by the commissioners court is valid only if the commissioners court notifies the attorney general of the delay or variance and the reasons for the delay or variance not later than the 30th day after the date the commissioners court grants the delay or variance.
