CHAPTER 19. WASTEWATER DISCHARGE AND TREATMENT.
Article V. Reporting and Sampling Requirements.
Sec. 19-5-5. Periodic compliance/self-monitoring reports.
(a) All industrial users shall, at a frequency determined by the director,
but in no case less than twice per year during the months of June and December,
submit a periodic compliance or self-monitoring report indicating the nature and
concentration of pollutants in the discharge which are limited by pretreatment
standards or pretreatment requirements. In addition, this report shall include a
record of all daily flows which during the reporting period exceeded the average
daily flow, and the measurement of estimated average and maximum daily flows for
the reporting period.
(b) The director may impose mass limitations on
industrial users which are using dilution to meet applicable pretreatment
standards or pretreatment requirements, or in other cases where the imposition
of mass limitations are appropriate. In such cases, the report required by
subsection (a) of this section shall indicate the mass of pollutants regulated
by pretreatment standards or pretreatment requirements 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 director, of pollutants contained therein which
are limited by the applicable pretreatment standards or pretreatment
requirements. The frequency of monitoring shall be prescribed in the applicable
pretreatment standard or pretreatment requirements. All analysis shall be
performed in accordance with procedures established by the Administrator
pursuant to Section 304(g) of the Act and contained in 40 CFR Part 136 and
amendments thereto or with any other test procedures approved by the
Administrator. Sampling shall be performed in accordance with this chapter and
the techniques approved by the Administrator.
(c) All wastewater samples
must be representative of the user's discharge. Wastewater monitoring and flow
measurement facilities shall be properly operated, kept clean, and maintained in
good working order at all times. The failure of a user to keep its monitoring
facility in good working order shall not be grounds for the user to claim that
sample results are unrepresentative of its discharge.
(d) If a user subject
to the reporting requirement in this section monitors any pollutant more
frequently than required by the director, using the procedures prescribed in
Section 19-5-14, the results of this monitoring shall be included in the
(e) At the discretion of the director and in consideration of such
factors as local high or low flow rates, holidays, budget cycles, etc., the
director may agree to alter the months during which the above reports are to he
submitted. Any revised dates shall be noted in the user's industrial wastewater
discharge permit. (Ord. No. 1271, § 1 (part).)
