Laboratory Supervisor Practice Test

To be accepted as a compliance monitoring method for a contaminant, where must the analytical method be listed?

In the lab's accreditation certificate In the facility's internal SOP In the EPA methods handbook, not required to be in CFR In the applicable section of 40 CFR

Correct Answer:

In the applicable section of 40 CFR

Explanation:

Regulatory acceptance hinges on being codified in the law. For environmental compliance monitoring, the analytical method used to measure a contaminant must be listed in the applicable section of 40 CFR. This is what makes a method officially enforceable for permit compliance and reporting. Lab accreditation certificates and internal SOPs demonstrate capability, but they don’t establish regulatory acceptance of a specific method. The EPA methods handbook is a useful reference, yet it isn’t enforceable on its own unless the method is incorporated into the CFR or into a permit. So, the method’s listing in the applicable section of 40 CFR is the official requirement for acceptance.
