Del. Code tit. 31, § 4307

No commissioner shall receive any compensation, whether in form of salary, per diem allowances or otherwise, for or in connection with the commissioner’s services as such commissioner. Each commissioner shall, however, be entitled to reimbursements, to the extent of appropriations or other funds available therefor, for any necessary expenditures in connection with the performance of the commissioner’s general duties or in connection with the construction or operation of any project. The authority may allocate such expenses among its project in such manner as it may consider proper.
