A plant is setting its minimum retention period for NPDES monitoring records. Under the general federal permit condition, which minimum applies unless the permit requires longer?
Answer: B. Keep records for at least 3 years
The general NPDES condition requires monitoring records to be retained for at least 3 years, with longer retention possible when required. A is shorter than the federal minimum, while C and D are longer periods rather than the stated general minimum. Source note: 40 CFR 122.41(j)(2).
An NPDES discharge report is ready 6 hr before the deadline. The preparer is not an authorized signatory. The authorized signer is off site, has remote access to the reporting portal, and offers to share login credentials so the on-site operator can submit. What should the plant do?
Answer: A. Have an authorized signer submit
With 6 hr remaining and remote access available, the authorized signer should use individual credentials to certify and submit the report. B shares another person's credentials, C omits certification, and D treats an unauthorized preparer as a signer without completing the authorization process.
