(a) A user who performs self-monitoring shall contract with an independent company (unless the requirement to use an independent company is waived in advance by the POTW Manager as determined appropriate by the Manager) to maintain, repair, and calibrate the sampling and flow measurement equipment and instruments used to monitor the user.
(b) The maintenance, repair, and calibration shall be performed as often as necessary to ensure that monitoring data is accurate and representative, and consistent with the accepted capability of the type of equipment used, and shall be at the sole cost of the user.
(c) A user shall keep a complete and accurate written record of all calibrations, inspections and maintenance done (including, without limitation, the date and time of the activity, a description of what was done and the methods used, the names of persons conducting the activity, and any required or recommended follow-up). The record shall also include a description of all problems discovered regarding the equipment whether in response to a regularly scheduled inspection or otherwise.
(d) The POTW, in any event, may inspect and test a user’s sampling and flow measurement equipment and instruments at all reasonable times.
(e) In no case shall a user’s failure to keep its equipment, instruments and facilities in good working order constitute grounds for the user to claim that sample results are unrepresentative of its discharge.
