[Ord. of 4-8-1999, § 1]
It shall be unlawful to discharge, without a permit, to the
POTW or to any public sewer tributary thereto, any wastewater except
as authorized by the Engineer in accordance with the provisions of
this chapter.
[Ord. of 4-8-1999, § 1]
Residential users are exempt from wastewater contribution/discharge
permit requirements.
[Ord. of 4-8-1999, § 1]
Wastewater contribution/discharge permits are issued to a specified
user for a specific operation. A wastewater contribution/discharge
permit shall not be assigned, transferred or sold to a new owner,
new user, different premises or a new or changed operation without
the approval of the Engineer. Any succeeding owner or user shall also
comply with the terms and conditions of the existing permit.
[Ord. of 4-8-1999, § 1]
All sampling and analyses of the characteristics of waters and
wastes to be submitted, or part of a wastewater contribution/discharge
permit application or report, shall be performed in accordance with
the techniques prescribed in 40 CFR Part 136 and amendments thereto
unless otherwise specified in an applicable pretreatment standard
or requirement. If 40 CFR Part 136 does not contain sampling and analytical
techniques for the pollutant in question, sampling and analysis must
be performed in accordance with procedures approved by the EPA. A
minimum of four grab samples must be used for pH, cyanide, total phenols,
oil and grease, sulfide and volatile organics. For all other pollutants,
twenty-four-hour composite samples must be obtained through flow-proportional
composite sampling techniques where feasible. The City Engineer may
waive flow proportional composite sampling for any industrial user
that demonstrates that flow-proportional sampling is infeasible. In
such cases, samples may be obtained through time-proportional composite
sampling techniques or through a minimum of four grab samples where
the user demonstrates that this will provide a representative sample
of the effluent being discharged.
[Ord. of 4-8-1999, § 1]
Users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all federal categorical pretreatment standards (as set forth in Section
14 1/2-50 of this chapter) local limits, the prohibitions set out in Section
14 1/2-52 of this chapter, and any other pretreatment standards or requirements within designs, specifications and time limitations as specified by the EPA, state or city, whichever is more stringent shall be provided, operated and maintained at the user's expense. Detailed designs, specifications and plans showing the pretreatment facilities and operating procedures shall be submitted to the Engineer for review and shall be approved by the Engineer before construction of the facility. Such designs, specifications and plans shall be prepared by and bear the seal of a professional engineer licensed by the State of New York. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the Engineer under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be approved by the Engineer prior to the initiation of the changes.
(a) Whenever deemed necessary, the City Engineer may
require users to restrict their discharge during peak flow periods,
designate that certain wastewater be discharged only into specific
sewers, relocate and/or consolidate points of discharge, separate
sewage wastestreams from industrial wastestreams and such other conditions
as may be necessary to protect the POTW and determine the user's compliance
with the requirements of this chapter.
(b) The City Engineer may require any user discharging
into the POTW to install and maintain, on their property and at their
expense, a suitable storage and flow-control facility to ensure equalization
of flow. A wastewater contribution/discharge permit may be issued
solely for flow equalization.
(c) Users with the potential to discharge flammable
substances may be required to install and maintain an approved combustible
gas detection meter.
[Ord. of 4-8-1999, § 1]
The City Engineer shall annually publish, in the largest daily
newspaper published in the city, a list of the industrial users which,
during the previous 12 months, were in significant noncompliance with
applicable pretreatment standards and requirements. The notification
shall also summarize any enforcement actions taken against the user(s)
during the same 12 months. Significant noncompliance shall mean that
the industrial user's violation meets one or more of the following
criteria:
(a) Chronic violations of wastewater discharge limits,
defined as those in which 66% or more of all of the measurements taken
during a six-month period exceed (by any magnitude) the daily maximum
limit or the average limit for the same pollutant parameter.
(b) Technical review criteria (TRC) violations are
those in which 33% or more of all the measurements for each pollutant
parameter taken during a six-month period equal or exceed the product
of the daily maximum limit or the average limit multiplied by the
applicable TRC (TRC equals 1.4 for BOD, TSS, fats, oil and grease,
and 1.2 for all other pollutants except pH).
(c) Any other violation of a pretreatment effluent
limit (daily maximum or long-term average) that the City Engineer
has determined, caused, alone or in combination with other discharges,
interference or pass-through (including endangering the health of
POTW personnel or the general public).
(d) Any discharge of a pollutant that has caused imminent
endangerment to human health, welfare or to the environment or has
resulted in the City Engineer's exercise of his emergency authority
to halt or prevent such a discharge.
(e) Failure to meet, within 90 days after the schedule
date, a compliance schedule milestone contained in the industrial
user's discharge permit or enforcement order issued by the City Engineer
for starting construction, completing construction or attaining final
compliance.
(f) Failure to provide, within 30 days after the due
date, required reports such as baseline monitoring reports, ninety-day
compliance reports, periodic self-monitoring reports and reports on
continued compliance.
(g) Failure to accurately report noncompliance.
(h) Any other violation or group of violations which
the City Engineer determines will adversely affect the operation or
implementation of the city's pretreatment program.
