The General Manager must require appropriate reporting from those significant industrial users with discharges that are not subject to categorical pretreatment standards. Significant noncategorical industrial users must submit to the General Manager at least once every six months (on dates specified by the General Manager) a description of the nature, concentration, and flow of the pollutants required to be reported by the General Manager. In cases where a local limit requires compliance with a best management practice or pollution prevention alternative, the user must submit documentation required by the General Manager to determine the compliance status of the user. These reports must be based on sampling and analysis performed in the period covered by the report, and in accordance with the techniques described in 40 C.F.R. part 136 and amendments thereto. Where 40 C.F.R. part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the Regional Administrator determines that the 40 C.F.R. part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures suggested by the POTW or other persons, approved by the Regional Administrator. This sampling and analysis may be performed by the city in lieu of the significant noncategorical industrial user.
