Upon receipt of such application, the commissioner, or some person appointed and designated by him, shall, within thirty (30) days, inspect the plant, and the locality where such applicant is conducting or proposes to conduct such business, and shall ascertain whether such applicant is a responsible and suitable person, financially and otherwise, to be entrusted with a license to conduct such business and that such applicant has fulfilled and complied with the requirements of all the sections of this chapter and of the rules and regulations authorized in this chapter relating to such business.

If such commissioner shall find that such applicant is such a responsible and suitable person to conduct such business, and that the plant of such applicant, and the methods of operation thereof comply with all the provisions of this chapter and with the rules and regulations authorized in this chapter, and that such business is located in a place permitted by this chapter, he shall thereupon issue to such applicant a certificate to that effect.

All licenses and certificates issued under this chapter shall remain effective until and unless voluntarily surrendered, or suspended or revoked, as provided in this chapter, conditioned, however, upon payment to the commissioner on or before July 15th subsequent to the year of issuance, of the required total annual license fee, which payment shall operate, without further application, to continue such licenses and certificates in full effect during each year for which such license fee shall be paid, unless sooner surrendered or suspended or revoked.
