(4) any other information required by rules adopted by the commission.

(b) Not later than the 60th day after the date of the completion or cessation of drilling, deepening, or otherwise altering the well, the driller shall deliver, send by first class mail, or provide electronically a copy of the well log to:

(1) the department;

(2) the Texas Commission on Environmental Quality; and

(3) the owner of the well or the person for whom the well was drilled.
