   2. (2) a person with a bachelor's degree in the chemical, environmental, physical or biological sciences, or engineering, with at least 16 college semester credit hours in the biological sciences, including, for microbiological testing, at least one course having microbiology as a major component, and at least two years of experience in environmental analysis of representative analytes for which the laboratory is approved or seeking approval; or
   3. (3) notwithstanding the requirements of paragraphs (1) and (2) of this subdivision, a person with an earned doctoral, master's, bachelor's, or associate's degree in an appropriate field of the sciences or applied sciences, with at least four college semester hours in general microbiology or a biological science course with a major microbiological component, and one year of experience in environmental analysis of representative analytes, may be a technical director of an approved laboratory, provided the laboratory is engaged in microbiological analysis limited to fecal coliform, total coliform and standard plate counts. Two year of equivalent and successful college education, including the microbiology requirement, may be substituted for an associate's degree.

10. (i) A technical direct of an approved laboratory engaged in radiochemical analysis shall be:

    1. (1) a person with an earned doctoral degree in chemistry, physics or engineering, with at least 24 college semester hours in chemistry, and at least one year of experience in radiochemical analysis of environmental samples;
