(A) fees to entities other than the department; and

(B) the Texas Workforce Commission's implementation costs; and

(2) for each exemption granted under Section 521.1015, 521.1016, or 521.1811, deposit to the credit of the Texas mobility fund an amount that is equal to the amount of the waived fee that would otherwise be deposited to the mobility fund.

(c) The department may not:

(1) request a transfer under Subsection (b)(1) if the balance of the account for the fiscal year is less than three times the amount expended in the previous fiscal year for the waivers provided by Sections 521.1015(e) and 521.1811; or

(2) grant an exemption under Section 521.1015, 521.1016, or 521.1811 if money is not available in the identification fee exemption account to meet the requirements of Subsection (b)(2).

(d) The department, in consultation with the Texas Workforce Commission, by rule shall establish a process by which transfers are made under Subsection (b).
