5.New Sources: All new sources subject to existing categorical pretreatment
standards shall submit a rep01t within ninety (90) days from the date of first discharge
demonstrating actual and continuing compliance with those standards.
6.The measured average daily and maximum daily flow, in gallons per day, to the POTWfrom each of the following:
a.Regulated process streams; and
b.Other streams as necessary to allow use of the combined v1aste stream formula of 40
CFR 403.6(e). l.Jl flov,rs shall be measured unless cost or feasibility justify allovling
a verifiable estimate of the flow;
Report on compliance with categorical pretreatment standard 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 shall submit to the Control Authority a report containing the information described in paragraphs A. I-9 of this section. For Industrial Users subject to equivalent mass or concentration limits established by the Control Authority in accordance with the procedures in§40.03.III5, this rep01t shall contain a reasonable measure of the User's

For all other Industrial Users subject to categorical Pretreatment Standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this rep01t shall include the User's actual production during the appropriate sampling period.

b.In addition, the User shall submit the results of sampling and analysis identifying the
nature and concentration ( or mass, where required by the Standard or Control
Authority) of regulated pollutants in the Discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. In cases where the Standard requires compliance with a Best Management Practice or pollution

Control Authority or the applicable Standards to determine compliance with the Standard;

necessary to comply with the requirements of this paragraph.
d.Samples should be taken immediately downstream from pretreatment facilities if suchexist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment the User should measure the flows and concentrations necessary to
allow use of the combined wastestream f01mula of §403.6(e) in order to evaluate
compliance with the Pretreatment Standards. Where an alternate concentration or
