Except as otherwise provided by this chapter, self-monitoring shall be conducted by each user to insure compliance with all applicable requirements of this chapter and other applicable laws and regulations. A user performing its own sampling shall submit the samples for analysis to a laboratory (which may include the user's own laboratory) approved by the WWTP Superintendent. A user performing its own sampling or monitoring shall record and maintain for all samples and monitoring the date, exact place, time (including start time and stop time) and method of sampling or measurement, and the name(s) of person(s) taking the samples or measurements; sampler programming information; the sample preservation techniques or procedures used; the full chain-of-custody for each sample; the dates the analyses were performed; who performed the analyses; the analytical techniques and methods used; quality assurance/quality control (QA/QC) procedures used and QA/QC data; and the results of the analyses. If sampling performed by a user indicates a violation, the user shall notify the WWTP Superintendent within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the POTW within 30 days after becoming aware of the violation (unless a shorter time period is specified by the WWTP Superintendent to the user), except that the user shall not be required to resample if (a) the POTW performs sampling at the user at a frequency of at least once per month, or (b) the POTW performs sampling at the user between the time when the user performs its initial sampling and the time when the user receives the results of the sampling that indicates the violation. If a user uses its own laboratory for sample analysis, the WWTP Superintendent may require the user to send split samples to an independent laboratory at a frequency specified by the Superintendent as a quality control check.
