The following conditions shall apply to the schedule required by §
73-49. The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (such events include hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction and beginning and conducting routine operations). No increment referred to above shall exceed nine months. The industrial user shall submit a progress report to the Executive Director no later than 14 days following each date in the schedule and the final date of compliance, including, as a minimum, whether or not the industrial user complied with the increment of progress, the reason for any delay and, if appropriate, the steps being taken by the industrial user to return to the established schedule. In no event shall more than nine months elapse between such progress reports to the Executive Director.
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 such pretreatment standards and requirements shall submit to the PSA a report containing the information described in §
73-49. For industrial users subject to equivalent mass or concentration limits established in accordance with the procedures in 40 CFR 403.6(c), this report shall contain a reasonable measure of the industrial 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 other measure of operation), this report shall include the industrial user's actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with §
73-39.
Each industrial user shall notify the Executive Director of any planned
significant changes to the industrial user's operations or system which
might alter the nature, quality or volume of its wastewater at least 30 days
before the change.
A. The Executive Director may require the industrial user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under §
73-38.
B. The Executive Director nay issue a wastewater discharge permit under §
73-40 or modify an existing wastewater discharge permit under §
73-44.
C. No industrial user shall implement the planned changed
condition(s) until and unless the Executive Director has responded to the
industrial user's notice.
D. For purposes of this requirement, flow increases of 10%
or greater and the discharge of any previously unreported pollutants shall
be deemed significant and reportable hereunder.
All industrial users not subject to categorical pretreatment standards
and not required to obtain a wastewater discharge permit shall provide appropriate
reports to the PSA as the Executive Director may require.
If sampling performed by an industrial user indicates a violation, the
industrial user must notify the control authority within 24 hours of becoming
aware of the violation. The industrial user shall also repeat the sampling
and analysis and submit the results of the repeat analysis to the control
authority within 30 days after becoming aware of the violation. The industrial
user is not required to resample if the POTW performs monitoring at the industrial
user's facility at least once a month or if the POTW performs sampling
between the time of the industrial user's initial sampling and the industrial
user's receipt of the results of this sampling.
All pollutant analyses, including sampling techniques, to be submitted
as part of a wastewater discharge permit application or report shall be performed
in accordance with the techniques prescribed in 40 CFR Part 136, unless otherwise
specified in an applicable categorical pretreatment standard. If 40 CFR Part
136 does not contain sampling or analytical techniques for the pollutant in
question, sampling and analyses must be performed in accordance with procedure
approved by the EPA.
The Executive Director may use a grab sample(s) to determine noncompliance
with pretreatment standards.
Written reports will be deemed to have been submitted on the date postmarked.
For reports which are not mailed, postage prepaid, into a mail facility serviced
by the United States Postal Service, the date of receipt of the report shall
govern.
Industrial users shall retain and make available for inspection and
copying all records and information required to be retained under this chapter.
These records shall remain available for a period of at least three years.
This period shall be automatically extended for the duration of any litigation
concerning compliance with this chapter or where the industrial user has been
specifically notified of a longer retention period by the Executive Director.
The PSA may require a user of sewer services to provide information
needed to determine compliance with this article. These requirements may include:
A. Wastewater discharge peak rate and volume over a specified
time period.
B. Chemical analyses of wastewaters.
C. Information on raw materials, processes and products
affecting wastewater volume and quality.
D. Quantity and disposition of specific liquid, sludge,
oil, solvent or other materials important to sewer use control.
E. A plot plan of sewers of the user's property, showing
sewer and pretreatment facility location.
F. Details of wastewater pretreatment facilities.
G. Details of systems to prevent and control the losses
of materials through spills to the municipal sewer.
All measurements, tests and analyses of the characteristics of waters
and wastes to which reference is made in this article shall be determined
in accordance with the latest edition of Standard Methods for the Examination
of Water and Wastewater, published by the American Public Health Association.
Sampling methods, location, times, durations and frequencies are to be determined
on an individual basis subject to approval by the PSA.
