A local municipality, the Monroe County Department of Public
Health, NYSDEC, EPA or such other State or federal agencies which
have enforcement powers may issue directives and/or orders calling
for the mandatory use of the POTW for reasons including, but not limited
to, disconnecting a Private Sewage Disposal System for the proper
discharge of Sewage or the discharge of Industrial Wastes and other
wastes to the County Sewer District.
Pretreatment or discharge control facilities shall be provided
for discharges to the POTW when required by New York State or federal
regulations or when, in the judgment of the Director, such facilities
are necessary to ensure compliance with the provisions of this Part
2 or for the control of Pollutants that are contained or may be contained
in any of the User's discharges or for the prevention or control
of Slug Discharges or spills. All such facilities shall be located
so as to be readily accessible for normal operations and maintenance
and shall be available for inspection by the Director as may be needed.
A. Contaminated groundwater discharges.
(1) The POTW may accept, by permission from the Director, discharges
from groundwater remediation projects under State or federal order
or from projects correcting environmental or public health issues.
The User must submit to the Director a written request to discharge
such groundwater. A Permit to discharge may be granted contingent
upon adherence to conditions, including but not limited to the following:
(a)
A complete description of the remediation site must be provided
and include: identification of all sources contributing to the discharge;
an estimate of the total volume of contaminated groundwater; a description
of the method that will be used to measure flow; and the time frame
of the project.
(b)
The contaminated groundwater, where applicable, must be treated
using best available technology for reducing Pollutants of concern.
The User must submit pertinent technical information and specifications
of the pretreatment system process components that will be used.
(c)
When a Storm Sewer is available, a letter must be obtained by
the User from the NYSDEC declaring that draining such discharge to
the POTW is in the public's best interest.
(d)
When and where applicable, all cleanup activities must be in
accordance with NYSDEC or EPA rules and regulations.
(e)
Submission of analytical test results required by the Director,
from a representative sample(s) of the contaminated groundwater to
be discharged. The parameters which must be tested are at the discretion
of the Director. The Director may set local limits for parameters
that are not listed herein.
(2) The User shall be subject to the Permit conditions specified in this
Part 2. Contaminated groundwater shall be discharged to the POTW only
at a location designated and permitted by the Director in writing
or in the case where the discharge is to a tributary of the County
POTW, only by the specific designation of the applicable owner/operator
of that particular sewerage system. The Director may require that
the discharge be limited to a specific time frame or a specific rate
of discharge.
B. Waste load allocations for Pollutants.
(1) The Director shall determine the hydraulic capacity and maximum allowable
mass loading for substances that limit process capacity for each Wastewater
Treatment Plant.
(2) The hydraulic capacity and maximum allowable mass loading for the
limiting waste substance(s) at each Wastewater Treatment Plant shall
include a reserve to establish the critical loading margin and shall
be in accordance with the following:
(a)
A portion shall represent a factor of safety to protect the
Wastewater Treatment Plant from unusual load conditions and also account
for data variability, including data quality and quantity; and
(b)
A portion shall represent an allowable growth rate in loading
over five years.
(3) When critical load is reached, the Director shall then determine
steps to protect the plant.
C. Flow and Pollutant loading equalization. No User shall cause disruption
to the POTW due to excessive flow and/or Pollutant loading. If conditions
warrant, the User shall install and maintain on its property or rental
property, at its expense, a suitable storage and flow control facility
to ensure equalization of flow and/or loading over a twenty-four-hour
period. The facility plan shall be reviewed and approved by the Director
and at a minimum shall be equipped with alarms and a rate of discharge
controller, regulation of which shall be at the discretion of the
Director.
D. Traps and interceptor devices. Commercial and Industrial Users may
be required to install an interceptor or trap for the removal of FOG,
grit or other harmful or flammable substances that may be permissible
for discharge. Degreasers, enzymes and similar substances that act
to temporarily emulsify or suspend FOG shall not be introduced into
any device designed to capture and retain FOG. All interceptors and
traps shall be maintained in accordance with manufacturer's specifications.
E. Spill containment facilities. A User shall provide, when required
by State or federal regulations or by the Director, facilities that
are necessary for the containment of any raw materials, products,
wastes or other potential Pollutants used or stored on the User's
premises in locations where a spill of the material could potentially
enter into the POTW. The Director may take into account whether or
not the material(s) may cause Nuisance, Interference or Pass-Through
when determining the requirement of such facilities.
F. Slug Discharge control plan. If the POTW decides that a slug control
plan is needed, the plan shall contain, at a minimum, the following
elements:
(1) Description of discharge practices, including nonroutine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the POTW of Slug Discharges,
with procedures for follow-up written notification within five days;
(4) If necessary, procedures to prevent adverse impact from accidental
spills, including inspection and maintenance of storage areas, handling
and transfer of materials, loading and unloading operations, control
of plant site runoff, worker training, building of containment structures
or equipment, measures for containing toxic organic pollutants (including
solvents), and/or measures and equipment for emergency response.
