(a)
Unless
exempted by the director, users required to complete a wastewater
discharge application and others determined necessary because of special
conditions specified by the director shall provide sampling facilities
of types and at locations approved by the director.
(b)
The
sampling facilities must be designed to allow inspection, sampling,
and flow measurement, if required, of the user’s specific discharges
and must be provided and maintained in a safe and operational condition
at the user’s expense. The sampling facilities must allow collection
in accordance with the requirements of 40 CFR part 136 as amended.
(c)
Except
in cases where the location is impractical or would cause undo hardship
to the user, the sampling facilities shall be located on the user’s
premises. In such cases, the city may allow the facility to be constructed
on the sidewalk or public street provided that the location will not
be obstructed in any manner.
(d)
Adequate
room must be provided at or near the facility to allow accurate sampling
and preparation of samples.
(e)
All
sampling facilities shall be constructed in accordance with applicable
local construction standards.
(f)
Construction
of sampling facilities shall be completed within a time period designated
by the director.
(g)
Failure
to provide proper sampling facilities shall be grounds for denial
of a permit and/or enforcement action, including denial of the right
to discharge to the POTW(s).
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a)
The
volume of flow discharged by a significant industrial user or user
shall be based upon metered water consumption as shown by the meter
readings maintained by the city.
(b)
Any
significant industrial user or other user as deemed necessary by the
director who procures any or all of its water from sources other than
the city and all or part of which is discharged into the POTW(s),
and who does not have an effluent meter shall install and maintain
at the user’s expense a water meter at each unmetered water
source.
(c)
Where
it can be shown to the satisfaction of the director that a substantial
portion of the water as measured by the aforesaid meter does not enter
the sanitary sewer of the city, the director may permit or require
the installation of additional meters in a manner as to measure the
actual water volume entering the POTW(s) of the city.
(d)
Whenever
meters other than those provided by the city are used for measuring
flows to the POTW(s), the meters shall:
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a)
All
pollutant analyses, including sampling techniques, submitted as part
of a wastewater discharge application or report, shall be performed
in accordance with the techniques prescribed in 40 CFR part 136 as
amended, unless otherwise specified in the categorical pretreatment
standard. If 40 CFR part 136 does not contain sampling or analytical
techniques for the pollutant in question, or EPA does not recommend
use of the 40 CFR part 136 techniques for the pollutant in question,
sampling and analyses must be performed in accordance with procedures
approved by EPA.
(b)
The
director shall have the right to require a user to submit quality
control analyses performed in conjunction with any analysis submitted
as required by this division or by a wastewater discharge permit.
If quality control information is not available or does not meet the
criteria specified in the approved technique, the submitted data can
be rejected and the user required to resubmit samples for analysis.
(c)
All
analyses performed under the analytical methods and sampling conditions
(i.e. preservation, holding time) specified in 40 CFR part 136 and
required by this division or wastewater discharge permit must be submitted
to the director in compliance with a schedule established by the director
and must be representative of the user’s discharge. Failure
to report valid data required by the director will be considered a
violation of this division.
(d)
If
more frequent analyses for regulated pollutants are performed by the
user using the techniques and at the appropriate sampling location
specified in this division or the wastewater discharge permit, the
results must be included in the reports submitted to the director.
(e)
Non-detectable
results can only be used to demonstrate a pollutant is not present
if the EPA approved method from 40 CFR part 136 with the lowest minimum
detection level for that pollutant was used in the analysis.
(Ordinance 2011-01, sec. 1, adopted 1/11/11)
(a)
The
director will designate samples collection procedures and the number
of samples to be collected over the course of discharge required to
satisfy reporting requirements. Data submitted must be obtained through
appropriate sampling and analysis performed during the period covered
by the report, based on data that is representative of conditions
occurring during the reporting period.
(b)
Except as indicated in subsections (c) and (d) below, the user must collect wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the director. Where time-proportional composites sampling or grab sampling is authorized by the city, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified by 40 CFR part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited in the field or at the laboratory prior to the analysis for cyanide, total phenols, and sulfides; 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 city, as appropriate. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
(c)
Samples
for oil and grease, temperature, pH, cyanide, phenols, sulfides, and
volatile organic compounds must be obtained using grab collection
techniques.
(d)
For sampling required in support of baseline monitoring and 90-day compliance reports required in sections 13-2-261 and 13-2-263, a minimum of four (4) 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 by section 13-2-264, the user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.
(e)
Sample
collection information, including but not limited to collection site,
sample collector, type of sample, date and time of collection, and
sample preservation shall be gathered and submitted along with the
analytical data required by this division. Appropriately completed
chain of custody forms must be submitted.
