[Adopted 5-13-2008 by L.L. No. 1-2008]
It is hereby determined that:
A. Land development activities and associated increases in site impervious
cover often alter the hydrologic response of local watersheds and
increase stormwater runoff rates and volumes, flooding, stream channel
erosion, or sediment transport and deposition;
B. This stormwater runoff contributes to increased quantities of waterborne
pollutants, including siltation of aquatic habitat for fish and other
desirable species;
C. Clearing and grading during construction tends to increase soil erosion
and add to the loss of native vegetation necessary for terrestrial
and aquatic habitat;
D. Improper design and construction of stormwater management practices
can increase the velocity of stormwater runoff, thereby increasing
stream bank erosion and sedimentation;
E. Impervious surfaces allow less water to percolate into the soil,
thereby decreasing groundwater recharge and stream baseflow;
F. Substantial economic losses can result from these adverse impacts
on the waters of the municipality;
G. Stormwater runoff, soil erosion and nonpoint source pollution can
be controlled and minimized through the regulation of stormwater runoff
from land development activities;
H. The regulation of stormwater runoff discharges from land development
activities in order to control and minimize increases in stormwater
runoff rates and volumes, soil erosion, stream channel erosion, and
nonpoint source pollution associated with stormwater runoff is in
the public interest and will minimize threats to public health and
safety;
I. Regulation of land development activities by means of performance
standards governing stormwater management and site design will produce
development compatible with the natural functions of a particular
site or an entire watershed and thereby mitigate the adverse effects
of erosion and sedimentation from development.
The purpose of this article is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing within this jurisdiction and to address the findings of fact in §
181-1 hereof. This article seeks to meet those purposes by achieving the following objectives:
A. Meet the requirements of minimum measures 4 and 5 of the SPDES general
permit for stormwater discharges from municipal separate stormwater
sewer systems (MS4s), Permit No. GP-02-02, or as amended or revised;
B. Require land development activities to conform to the substantive
requirements of the NYS Department of Environmental Conservation State
Pollutant Discharge Elimination System (SPDES) general permit for
construction activities, Permit No. GP-02-01, or as amended or revised;
C. Minimize increases in stormwater runoff from land development activities
in order to reduce flooding, siltation, increases in stream temperature,
and stream bank erosion and maintain the integrity of stream channels;
D. Minimize increases in pollution caused by stormwater runoff from
land development activities which would otherwise degrade local water
quality;
E. Minimize the total annual volume of stormwater runoff which flows
from any specific site during and following development to the maximum
extent practicable; and
F. Reduce stormwater runoff rates and volumes, soil erosion and nonpoint
source pollution, wherever possible, through stormwater management
practices and to ensure that these management practices are properly
maintained and eliminate threats to public safety.

SPECIAL CONDITIONS
A.
Discharge compliance with water quality standards: the condition
that applies where a municipality has been notified by NYSDEC that
the discharge of stormwater authorized under their MS4 permit may
have caused or has the reasonable potential to cause or contribute
to the violation of an applicable water quality standard. Under this
condition, the municipality must take all necessary actions to ensure
future discharges do not cause or contribute to a violation of water
quality standards.
B.
303(d)-listed waters: the condition in the municipality's
MS4 permit that applies where the MS4 discharges to a 303(d)-listed
water. Under this condition, the stormwater management program must
ensure no increase of the listed pollutant of concern to the 303(d)-listed
water.
C.
TMDL (total maximum daily load) strategy: the condition in the
municipality's MS4 permit where a TMDL, including requirements
for control of stormwater discharges, has been approved by the EPA
for a water body or watershed into which the MS4 discharges. If the
discharge from the MS4 did not meet the TMDL stormwater allocations
prior to September 10, 2003, the municipality was required to modify
its stormwater management program to ensure that reduction of the
pollutant of concern specified in the TMDL is achieved.
D.
The condition in the municipality's MS4 permit that applies
if a TMDL is approved in the future by the EPA for any water body
or watershed into which an MS4 discharges. Under this condition, the
municipality must review the applicable TMDL to see if it includes
requirements for control of stormwater discharges. If an MS4 is not
meeting the TMDL stormwater allocations, the municipality must, within
six months of the TMDL's approval, modify its stormwater management
program to ensure that reduction of the pollutant of concern specified
in the TMDL is achieved.
STORMWATER
Rainwater, snowmelt, drainage and uncontaminated groundwater.
303(d) LIST
A list of all surface waters in the state for which beneficial
uses of the water (drinking, recreation, aquatic habitat, and industrial
use) are impaired by pollutants, prepared periodically by NYSDEC as
required by Section 303(d) of the Clean Water Act. 303(d)-listed waters are estuaries, lakes and streams
that fall short of state surface water quality standards and are not
expected to improve within the next two years.
TMDL
Total maximum daily load.
TOTAL MAXIMUM DAILY LOAD
The maximum amount of a pollutant to be allowed to be released
into a water body so as not to impair uses of the water, allocated
among the sources of that pollutant.
WASTEWATER
Water that is not stormwater, is contaminated with pollutants
and is or will be discarded.
The Stormwater Management Officer(s) [SMO(s)] shall administer,
implement, and enforce the provisions of this article.
No persons shall operate a failing individual sewage treatment
system in areas tributary to the municipality's MS4. A failing
individual sewage treatment system is a system which has one or more
of the following conditions:
A. The backup of sewage into a structure.
B. Discharges of treated or untreated sewage onto the ground surface.
C. A connection or connections to a separate stormwater sewer system.
D. Liquid level in the septic tank above the outlet invert.
E. Structural failure of any component of the individual sewage treatment
system that could lead to any of the other failure conditions as noted
in this section.
F. Contamination of off-site groundwater that can reasonably be attributed
to the individual sewage treatment system.
Any person subject to an industrial or construction activity
SPDES stormwater discharge permit shall comply with all provisions
of such permit. Proof of compliance with said permit shall be required
by the municipality in a form acceptable to the NYSDEC prior to the
allowing of discharges to the MS4.
Notwithstanding other requirements of law, as soon as any person
responsible for a property or operation or responsible for emergency
response for a property or operation has information of any known
or suspected release of materials which are resulting or may result
in illegal discharges or pollutants discharging into the MS4, said
person shall take all necessary steps to ensure the discovery, containment,
and cleanup of such release. In the event of such a release of hazardous
materials, said person shall immediately notify emergency response
agencies, the municipality, and the responsible MS4 of the occurrence
via emergency dispatch services. In the event of a release of nonhazardous
materials, said person shall notify the municipality and responsible
MS4 in person or by telephone or facsimile no later than the next
business day. Notifications in person or by telephone shall be confirmed
by written notice addressed and mailed to the municipality within
three business days of the telephone notice. If the discharge of prohibited
materials emanates from a commercial or industrial establishment,
the owner or operator of such establishment shall also retain an on-site
written record of the discharge and the actions taken to prevent its
recurrence. Such records shall be retained for at least three years.
Any person receiving a notice of violation may appeal the determination
of the SMO to the Village Board of Trustees within 15 days of its
issuance, which shall hear the appeal within 30 days after the filing
of the appeal and, within five days of making its decision, file its
decision in the office of the Municipal Clerk and mail a copy of its
decision by certified mail to said person.
It shall be unlawful for any person to violate any provision
or fail to comply with any of the requirements of this article. If
a person has violated or continues to violate the provisions of this
article, the SMO may petition for a preliminary or permanent injunction
restraining the person from activities which would create further
violations or compelling the person to perform abatement or remediation
of the violation.
In addition to the enforcement processes and penalties provided,
any condition caused or permitted to exist in violation of any of
the provisions of this article is a threat to public health, safety,
and welfare and is declared and deemed a nuisance and may be summarily
abated or restored at the violator's expense, and/or a civil
action to abate, enjoin, or otherwise compel the cessation of such
nuisance may be taken.
The remedies listed in this article are not exclusive of any
other remedies available under any applicable federal, state or local
law, and it is within the discretion of the authorized enforcement
agency to seek cumulative remedies.
