Notes:<br />

a. The “monthly geometric mean” is the geometric mean of all samples taken during the calendar month. A non-detect value may be<br />

substituted with a value of 1 for the purpose of calculating the geometric mean. If only one sample is collected, the result of that<br />

sample is the geometric mean.<br />

b. The “monthly average” is the average of all samples taken during the calendar month. If only one sample is collected, the result of<br />

that sample is the monthly average. A non-detect value may be substituted with a value of 0 for the purpose of calculating the<br />

monthly average.<br />

c. Analytical results below the method detection limit for the method used shall be deemed compliant with the effluent limits.<br />

d. The specific pollutants are listed in the most recent version of the Department approved QA/QC plan.<br />
