Editor's Note: Local Law No. 4-2010, adopted 3-15-2010, provided that Art. XII of Ch. 305, Zoning, be moved to Art. I of this chapter.
The article shall be known as the "Village of Tarrytown Stormwater Management and Erosion and Sediment Control Local Law."
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 water-borne pollutants, flooding, siltation of aquatic habitats for fish and other desirable species.
C. 
Clearing and grading during construction tend to increase soil erosion and add to the loss of native vegetation necessary for terrestrial and aquatic habitats.
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 non-point-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 non-point-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 herein. This article seeks to meet those purposes by achieving the following objectives:
A. 
Meeting 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. 
Requiring land development activities to conform to the substantive requirements of the New York State Department of Environmental Conservation State Pollutant Discharge Elimination System (SPDES) general permit for construction activities GP-02-01, or as amended or revised.
C. 
Minimizing increases in stormwater runoff from land development activities in order to reduce flooding, siltation, increases in stream temperature, and streambank erosion and maintain the integrity of stream channels.
D. 
Minimizing increases in pollution caused by stormwater runoff from land development activities which would otherwise degrade local water quality.
E. 
Minimizing the total annual volume of stormwater runoff which flows from any specific site during and following development to the maximum extent practicable.
F. 
Reducing stormwater runoff rates and volumes, soil erosion and non-point-source pollution, wherever possible, through stormwater management practices and ensuring that these management practices are properly maintained and eliminate threats to public safety.
In accordance with § 10 of the Municipal Home Rule Law of the State of New York, the Village Board of Trustees of the Village of Tarrytown has the authority to enact local laws and amend local laws for the purpose of promoting the health, safety or general welfare of the Village of Tarrytown and for the protection and enhancement of its physical environment.

[Added 1-17-2012 by L.L. No. 2-2012]
A. 
Activities that are subject to the requirements of this section are those types of activities that:
(1) 
Cause or contribute to a violation of the municipality's MS4 SPDES permit.
(2) 
Cause or contribute to the municipality being subject to the special conditions as defined in § 258-13 of this article.
B. 
Upon notification to a person that he or she is engaged in activities that cause or contribute to violations of the municipality's MS4 SPDES permit authorization, that person shall take all reasonable actions to correct such activities such that he or she no longer causes or contributes to violations of the municipality's MS4 SPDES permit authorization.
A. 
Best management practices. Where the SMO has identified illicit discharges as defined in § 258-13 or activities contaminating stormwater as defined in § 258-18, the municipality may require implementation of best management practices (BMPs) to control those illicit discharges and activities.
(1) 
The owner or operator of a commercial or industrial establishment shall provide, at his, her or its own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the MS4 through the use of structural and nonstructural BMPs.
(2) 
Any person responsible for a property or premises which is or may be the source of an illicit discharge as defined in § 258-13 or an activity contaminating stormwater as defined in § 258-19, may be required to implement, at said person's expense, additional structural and nonstructural BMPs to reduce or eliminate the source of pollutant(s) to the MS4.
(3) 
Compliance with all terms and conditions of a valid SPDES permit authorizing the discharge of stormwater associated with industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this section.
A. 
The SMO may, without prior notice, suspend MS4 discharge access to a person when such suspension is necessary to stop an actual or threatened discharge which presents or may present imminent and substantial danger to the environment, to the health or welfare of persons, or to the MS4. The SMO shall notify the person of such suspension within a reasonable time thereafter, in writing, with the reasons for the suspension. If the violator fails to comply with a suspension order issued in an emergency, the SMO may take such steps as deemed necessary to prevent or minimize damage to the MS4 or to minimize danger to persons.
B. 
Suspension due to the detection of illicit discharge. Any person discharging to the municipality's MS4 in violation of this article may have his, her or its MS4 access terminated if such termination would abate or reduce an illicit discharge. The SMO will notify a violator in writing of the proposed termination of its MS4 access and the reasons therefor. The violator may petition the SMO for a reconsideration and hearing. Access may be granted by the SMO if he/she finds that the illicit discharge has ceased and the discharger has taken steps to prevent its recurrence. Access may be denied if the SMO determines, in writing, that the illicit discharge has not ceased or is likely to recur. A person commits an offense if the person reinstates MS4 access to premises terminated pursuant to this section, without the prior approval of the SMO.
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 may be required in a form acceptable to the municipality prior to the allowing of discharges to the MS4.
A. 
Applicability. This section applies to all facilities that the SMO must inspect to enforce any provision of this article, or whenever the authorized enforcement agency has cause to believe that there exists, or potentially exists, in or upon any premises any condition which constitutes a violation of this article.
B. 
Access to facilities.
(1) 
The SMO shall be permitted to enter and inspect facilities subject to regulation under this article as often as may be necessary to determine compliance with this article. If a discharger has security measures in force which require proper identification and clearance before entry into its premises, the discharger shall make the necessary arrangements to allow access to the SMO.
(2) 
Facility operators shall allow the SMO ready access to all parts of the premises for the purposes of inspection, sampling, examination and copying of records as may be required to implement this article.
(3) 
The municipality shall have the right to set up, on any facility subject to this article, such devices as are necessary in the opinion of the SMO to conduct monitoring and/or sampling of the facility's stormwater discharge.
(4) 
The municipality has the right to require the facilities subject to this article to install monitoring equipment as is reasonably necessary to determine compliance with this article. The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the discharger at its own expense. All devices used to measure stormwater flow and quality shall be calibrated to ensure their accuracy.
(5) 
Unreasonable delays in allowing the municipality access to a facility subject to this article is a violation of this article. A person who is the operator of a facility subject to this article commits an offense if the person denies the municipality reasonable access to the facility for the purpose of conducting any activity authorized or required by this article.
(6) 
If the SMO has been refused access to any part of the premises from which stormwater is discharged, and he/she is able to demonstrate probable cause to believe that there may be a violation of this article, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program designed to verify compliance with this article or any order issued hereunder, then the SMO may seek issuance of a search warrant from any court of competent jurisdiction.
Notwithstanding other requirements of law, as soon as any person responsible for a facility or operation, or responsible for emergency response for a facility or operation, has information of any known or suspected release of materials which is 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 of the occurrence via emergency dispatch services. In the event of a release of nonhazardous materials, said person shall notify the municipality, 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 thee 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.
A. 
Notice of violation. When the municipality's SMO finds that a person has violated a prohibition or failed to meet a requirement of this article, he/she may order compliance by written notice of violation to the responsible person. Such notice may require, without limitation:
(1) 
The elimination of illicit connections or discharges;
(2) 
That violating discharges, practices, or operations shall cease and desist;
(3) 
The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property;
(4) 
The performance of monitoring, analyses, and reporting;
(5) 
Payment of a fine; and
(6) 
The implementation of source control or treatment BMPs. If abatement of a violation and/or restoration of affected property is required, the notice shall set forth a deadline within which such remediation or restoration must be completed. Said notice shall further advise that, should the violator fail to remediate or restore within the established deadline, the work will be done by a designated governmental agency or a contractor, and the expense thereof shall be charged to the violator.
B. 
Penalties. In addition to or as an alternative to any penalty provided herein or by law, any person who violates the provisions of this article shall be guilty of a violation punishable by a fine not exceeding $350 or imprisonment for a period not to exceed six months, or both, for conviction of a first offense; for conviction of a second offense, both of which were committed within a period of five years, punishable by a fine not less than $350 nor more than $700 or imprisonment for a period not to exceed six months, or both; and upon conviction for a third or subsequent offense, all of which were committed within a period of five years, punishable by a fine not less than $700 nor more than $1,000 or imprisonment for a period not to exceed six months, or both. However, for the purposes of conferring jurisdiction upon courts and judicial officers generally, violations of this article shall be deemed misdemeanors; and for such purpose only, all provisions of law relating to misdemeanors shall apply to such violations. Each week's continued violation shall constitute a separate additional violation.
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 the discharger.
A. 
If the violation has not been corrected pursuant to the requirements set forth in the notice of violation or, in the event of an appeal, within five business days of the decision of the municipal authority upholding the decision of the SMO, then the SMO shall request the owner's permission for access to the subject private property to take any and all measures reasonably necessary to abate the violation and/or restore the property.
B. 
If refused access to the subject private property, the SMO may seek a warrant in a court of competent jurisdiction to be authorized to enter upon the property to determine whether a violation has occurred. Upon determination that a violation has occurred, the SMO may seek a court order to take any and all measures reasonably necessary to abate the violation and/or restore the property. The cost of implementing and maintaining such measures shall be the sole responsibility of the discharger.
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.
A. 
Where a person has violated a provision of this article, he/she may be eligible for alternative remedies in lieu of a civil penalty, upon recommendation of the Municipal Attorney and concurrence of the Municipal Code Enforcement Officer, where:
(1) 
The violation was unintentional.
(2) 
The violator has no history of previous violations of this article.
(3) 
Environmental damage was minimal.
(4) 
The violator acted quickly to remedy the violation.
(5) 
The violator cooperated in investigation and resolution.
B. 
Alternative remedies may consist of one or more of the following:
(1) 
Attendance at compliance workshops.
(2) 
Storm drain stenciling or storm drain marking.
(3) 
River, stream or creek cleanup activities.
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.
This article shall be in full force and effect 60 days after its final passage and adoption. All prior laws and parts of law in conflict with this article are hereby repealed.
