1. Any user subject to a pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the city sewer system, shall submit to the city and to the Orem City POTW manager during the months of April and October, for the respective preceding six-month period, unless required more frequently in the pretreatment standard or by the city, a report indicating the nature and concentration of pollutants in the effluent which are limited by such pretreatment standards. In addition, this report shall include a record of all daily flows during the reporting period. At the discretion of the city and in consideration of such factors as local high or low flow rates, holidays, budget cycles' etc., the city may alter the months during which the above reports are to be submitted.

2. The city may impose mass limitations on users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by Subsection 1 of this section shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user. These reports shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where requested by the city of pollutants contained therein which are limited by the applicable pretreatment standards. The frequency of monitoring shall be prescribed in the applicable pretreatment standard. All analysis shall be performed in accordance with procedures established by the EPA Administrator pursuant to Section 304(h) of the Act and contained in 40 CFR, Part 136 and amendments thereto, or with any other test procedures approved by techniques approved by the EPA Administrator.
