(a) All appropriation acts of all state agencies subject to the provisions of this subchapter shall be governed by the provisions of this subchapter with respect to grades, class titles, salary increases, salary increase eligibility, and other provisions unless special language in the appropriation act of the state agency specifically allows the state agency to provide salary increases, grade assignments, class title assignments, salary increase eligibility, and other provisions different from those provided by this subchapter.

(b) Where the intent of the General Assembly, by amendment to appropriation bills, is to allow a higher grade for a classification than that listed in this subchapter, the grade assigned to the classification in the appropriation act for the classification, as designated with the higher grade level, shall be the grade level for the classification in the state agency during the biennium.

(c) When a higher salary grade level is authorized in this subchapter for classifications which are not reflected in the appropriation action of a state agency, this subchapter shall set the salary grade levels to be authorized in a state agency's appropriation act for the biennium unless special language in the appropriation act of a state agency allows the state agency to provide salary increases other than that provided in this subchapter.

(d) It is the intent of this section that the respective state agencies governed by the provisions of this subchapter be authorized to allow salary grade levels as provided in the appropriation acts of the state agencies, provided that the rules which apply to salary increases under the provisions of this subchapter shall not be waived unless special language in the appropriation act of the state agency authorizes the state agency to provide increases other than those authorized under the provisions of this subchapter.
