2. All persons required to obtain a permit, certificate or approval pursuant to the waste transporter permit requirements set forth in title 15 of article 27 of this chapter shall submit annually to the department a fee in the amount of five hundred dollars ($500.00) for the first vehicle permitted, certified or approved for the transportation of regulated medical waste, and two hundred dollars ($200.00) for each additional vehicle so permitted, certified or approved. Provided, however, that where a city or county is delegated the authority to administer the state waste transporter program pursuant to subdivision four of section 27-0305 of this chapter and such city or county collects a fee in connection with the issuance of a permit, certificate or approval for a waste transporter, no additional liability for fees under this section shall accrue.
