The STA and its employees shall not discriminate on the basis of race, color, sex, national origin, religion, age, or disability in the award and administration of STA contracts. It is the intention of the STA to create a level playing field on which DBEs can compete fairly for contracts and subcontracts relating to the STA’s construction, procurement and professional services activities.
