Conditions specified in §
176-6.02K shall apply to any compliance schedule required by the City.
Any discharger who experiences an upset in operations which
places the discharger in a temporary state of noncompliance with this
chapter shall inform the City thereof immediately upon first awareness
of the commencement of the upset. Where such information is given
orally, the City employee shall produce a written follow-up report
within five days. The report shall specify:
A. The description of the upset, the cause thereof and the upset's
impact on a discharger's compliance status;
B. The duration of noncompliance, including exact dates and times of
noncompliance and, if the noncompliance continues, the time by which
compliance is reasonably expected to occur;
C. All steps taken or to be taken to reduce, eliminate, and prevent
recurrence of such an upset or other condition of noncompliance. A
documented and verified bona fide operating upset shall be an affirmative
defense to any enforcement action brought by the City against a discharger
for any noncompliance with this chapter, which arises out of violations
alleged to have occurred during the period of the upset.
Each discharger must notify the Director of any significant
changes to the discharger's operations or system which may alter
the nature, quality, or volume of its wastewater at least 14 days
before the change.
A. The Director may require the discharger to submit such information
deemed necessary to evaluate the changed condition, including submission
of a WDP application.
B. The Director may issue a WDP or modify an existing WDP in response
to changed conditions or anticipated changed conditions.
In the case of any discharge, including, but not limited to,
accidental discharges, discharges of a nonroutine, episodic nature,
a noncustomary batch discharge, a slug discharge or slug load, that
might cause potential problems for the WRRF, the discharger shall
immediately notify the Director of the incident. This notification
shall include date and time, location of discharge, type of waste,
concentration and volume, if known, and corrective actions taken by
the discharger.
A. Within five days following such discharge, the discharger shall,
unless waived by the Director, submit a detailed written report describing
the cause(s) of the discharge and the measures to be taken by the
discharger to prevent similar future occurrences. Such notification
shall not relieve the discharger of any expense, loss, damage, or
other liability which might be incurred because of damage to the WRRF,
natural resources, or any other damage to person or property; nor
shall such notification relieve the discharger of any fines, penalties,
or other liability which may be imposed pursuant to this chapter.
B. A notice shall be permanently posted on the discharger's bulletin
board or other prominent place advising employees who to call in the
event of a discharge described in this section. Employers shall ensure
that all employees who could cause such a discharge to occur are advised
of the emergency notification procedure.
All dischargers not required to obtain a WDP shall provide appropriate
reports to the Director as the Director may require.
If sampling performed by a discharger indicates a violation,
the Director must be notified within 24 hours of the discharger's
becoming aware of the violation. The discharger shall be required
to repeat sampling in conformance with WDP requirements and conditions.
Unless authorized by Maine Hazardous Waste Management Rules
and thereafter approved by the Director, there shall be no discharge
of hazardous waste to the City's sewers or WRRF.
All pollutant analyses, including sampling techniques, to be
submitted as part of a WDP application or report, shall be performed
in accordance with the techniques prescribed in 40 CFR Part 136 and
amendments thereto. If 40 CFR Part 136 does not contain sampling or
analytical techniques for the pollutant in question, or where the
EPA determines that Part 136 sampling and analytical techniques are
inappropriate for the pollutant in question, sampling and analyses
shall be performed by using validated analytical methods or any other
applicable sampling and analytical procedures, including procedures
suggested by the Director or other parties approved by EPA.
The types of samples collected to satisfy reporting requirements
must be based on data obtained through appropriate sampling and analysis
performed during the period covered by the report, and based on data
that is representative of conditions occurring during the reporting
period.
A. Except as indicated in Subsections
B and
C below, the discharger must collect wastewater samples using twenty-four-hour, flow proportional composite sampling techniques, unless the Director authorizes time proportional composite sampling or grab sampling. Where time proportional composite sampling or grab sampling is authorized, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a twenty-four-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the Director, as appropriate. In addition, grab samples may be required to show compliance with instantaneous limits.
B. Samples for oil and grease, temperature, pH, cyanide, total phenols,
sulfides, and volatile organic compounds, if required, must be obtained
using grab collection techniques.
C. A minimum of four grab samples must be used for pH, cyanide, total
phenols, oil and grease, sulfide and volatile organic compounds for
facilities for which historical sampling data do not exist; for facilities
for which historical sampling data are available, the Director may
authorize a lower minimum. For the reports required in a discharger's
WDP or this chapter, the discharger is required to collect the number
of grab samples necessary to assess and assure compliance with applicable
WDP requirements.
Written reports will be deemed to have been submitted on the
date postmarked. For reports which are not mailed the date of receipt
of the report shall govern.
