Section 310.604  Report on Compliance with Deadline

Within 90 days following the date for final compliance with applicable categorical pretreatment standards or, in the case of a new source, following commencement of the introduction of wastewater into the POTW, any industrial user subject to pretreatment standards and requirements must submit to the Control Authority a report containing the information described in Sections 310.602(d) through (f).  For industrial users subject to equivalent mass or concentration limits established by the Control Authority in accordance with procedures in Sections 310.230, this report must contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or another measure of operation), this report must include the user's actual production during the appropriate sampling period.
