[Adopted 11-13-2007 by L.L. No. 7-2007]
The purpose of this article is to provide for the health, safety and general welfare of the citizens of the Village of Walden through the regulation of nonstormwater discharges to the municipal separate storm sewer system (MS4) to the maximum extent practicable as required by federal and state law. This article establishes methods for controlling the introduction of pollutants into the MS4 in order to comply with requirements of the SPDES general permit for municipal separate storm sewer systems. The objectives of this article are:
To meet the requirements of the SPDES General Permit for Stormwater Discharges from MS4s, Permit No. GP-02-02, or as amended or revised;
To regulate the contribution of pollutants to the MS4 since such systems are not designed to accept, process or discharge nonstormwater wastes;
To prohibit illicit connections, activities and discharges to the MS4;
To establish legal authority to carry out all inspection, surveillance and monitoring procedures necessary to ensure compliance with this article; and
To promote public awareness of the hazards involved in the improper discharge of trash, yard waste, lawn chemicals, pet waste, wastewater, grease, oil, petroleum products, cleaning products, paint products, hazardous waste, sediment and other pollutants into the MS4.

The Stormwater Management Officer 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 Stormwater Management Officer shall notify the person of such suspension within a reasonable time thereafter in writing of the reasons for the suspension. If the violator fails to comply with a suspension order issued in an emergency, the Stormwater Management Officer may take such steps as deemed necessary to prevent or minimize damage to the MS4 or to minimize danger to persons.
Any person discharging to the municipality's MS4 in violation of this article may have his/her MS4 access terminated if such termination would abate or reduce an illicit discharge. The Stormwater Management Officer will notify a violator in writing of the proposed termination of its MS4 access and the reasons therefor. The violator may petition the Stormwater Management Officer for a reconsideration and hearing. Access may be granted by the Stormwater Management Officer 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 Stormwater Management Officer 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 Stormwater Management Officer.
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.
Applicability. This section applies to all facilities that the Stormwater Management Officer 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.
Access to facilities.
The Stormwater Management Officer 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 that require proper identification and clearance before entry into its premises, the discharger shall make the necessary arrangements to allow access to the Stormwater Management Officer.
Facility operators shall allow the Stormwater Management Officer 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.
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 Stormwater Management Officer to conduct monitoring and/or sampling of the facility's stormwater discharge.
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.
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. If the Stormwater Management Officer 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 Stormwater Management Officer 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 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 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 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.
Notice of violation. When the municipality's Stormwater Management Officer 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:
The elimination of illicit connections or discharges;
That violating discharges, practices, or operations shall cease and desist;
The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property;
The performance of monitoring, analyses, and reporting;
Payment of a fine; and
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.
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. Each week's continued violation shall constitute a separate additional violation.
Any person receiving a notice of violation may appeal the determination of the Stormwater Management Officer 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 Village Clerk and mail a copy of its decision by certified mail to the discharger.
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 Village Board of Trustees upholding the decision of the Stormwater Management Officer, then the Stormwater Management Officer 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.
If refused access to the subject private property, the Stormwater Management Officer may seek a warrant in a court of competent jurisdiction to be authorized to enter upon the property and 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 Stormwater Management Officer 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
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:
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.
[Adopted 11-27-2007 by L.L. No. 8-2007]
The Village of Walden finds that land development activities, associated increases in site impervious cover, disturbances to the natural vegetative cover, and changes to the topography of the land can often alter the hydrologic response of local watersheds and increase stormwater runoff rates and volumes. These changes to the hydrology of the watershed can cause an increase in flooding, stream bank erosion, impairment to aquatic resources from silt or other pollutants, degradation of water quality and a loss of wildlife habitat. Land development activities can also cause unchecked erosion, sediment transport and deposition that can impair aquatic resources, clog drainageways and cause increased flooding. The potential impairment of the Village's natural resources caused by unchecked erosion, sedimentation and increased stormwater runoff results in a significant economic and social loss to the community. It is the purpose of this article to protect the public health, safety and welfare in the Village of Walden and its aquatic resources by establishing minimum requirements for stormwater management, preventing erosion and controlling sedimentation for activities which cause changes to the watershed hydrology and may increase erosion and sediment transport, including but not limited to construction activities, land alterations including excavation, filling, grading, land stripping and tree clearing, and increases in the rate of stormwater runoff.
Regulating land development activities by means of performance standards governing stormwater management, erosion and sediment control 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 stormwater runoff from changes in the natural conditions due to development. It will also protect the Village and other governmental bodies from the additional expense of having to undertake, as a public obligation, increased maintenance of stormwater management practices, programs of repairing roads and other public facilities, of providing flood protection facilities and of compensating private property owners for the destruction of properties arising from the adverse effects of site preparation and construction.
To accomplish the aforementioned purpose, the Board of Trustees of the Village of Walden has promulgated these standards and regulations, which seek to achieve the following objectives:
Minimize increases in peak rate of 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;
Minimize increases in pollution caused by stormwater runoff from land development activities which would otherwise degrade local water quality;
Minimize the total volume of stormwater runoff which flows from any specific site during and following development to the maximum extent practicable in order to minimize the economic impact of installation, operation and maintenance of drainage facilities;
Reduce soil erosion and sediment transport, wherever possible, through appropriate structural and nonstructural best management practices (BMPs), and to ensure that these management practices are properly maintained to eliminate threats to public safety.
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; and
Require 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.

Seeded with perennial rye grass. Seed shall be applied at the rate of not less than five pounds per 1,000 square feet.
Mulched with not less than one inch and not more than three inches of straw (two tons per acre) and anchored in a suitable manner.
Temporary on-site sedimentation basins for the immediate control of erosion and sediment transport are to be provided when and where required or ordered. The length, width and depth of such basins are to be determined in the field in accordance with the New York Standards and Specifications for Erosion and Sediment Control.
All erosion control structures are to be maintained in proper functioning order and are to be replaced or repaired as necessary.
Construction equipment shall not unnecessarily cross live streams except by means of bridges and culverts or other approved methods.
Wherever feasible, natural vegetation should be retained and protected.
Only the smallest practical area of land should be exposed at any one time during development.
Erosion control requirements shall include surface stabilization measures applied as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than seven days after the construction activity in that portion of the site has temporarily or permanently ceased. From November 1 through March 31, any disturbed area must be stabilized using a heavy mulch layer, a rolled erosion control product or another method that does not require seed germination to control erosion.
The permanent final vegetation and structures shall be installed as soon as practical and as may be directed by the Stormwater Management Officer or Village Engineer.
All erosion control measures employed during construction shall comply with the standards found in New York Standards and Specifications for Erosion and Sediment Control, latest edition.
Phasing shall be required on all sites disturbing greater than five acres, with the size of each phase to be established by the Planning Board or Stormwater Management Officer.
The standards and requirements contained herein shall be applied in reviewing and approving all permits pursuant to this article.
An erosion and sediment control plan shall seek to return the quality of the stormwater leaving the site to its predisturbance condition to the maximum extent practicable.
Excavation, filling, grading and stripping shall be permitted to be undertaken only in such locations and in such a manner as to minimize the potential of erosion and sediment and the threat to the health, safety and welfare of neighboring property owners and the general public. Alterations of grade or disturbances to the natural vegetative cover on slopes greater than 30% shall be avoided.
Site preparation and construction shall be fitted to the vegetation, topography and other natural features of the site and shall preserve as many of these features as feasible.
The control of erosion and sediment shall be a continuous process undertaken as necessary prior to, during and after site preparation and construction.
The smallest practical area of land shall be exposed by site preparation at any given time.
Mulching or temporary vegetation suitable to the site shall be used where necessary to protect areas exposed by site preparation, and permanent vegetation which is well adapted to the site shall be installed as soon as practical.
Where slopes that have been exposed or regraded during site preparation are to be revegetated, the slopes shall not be of such steepness that vegetation cannot be readily established or that problems of erosion or sediment may result.
Site preparation and construction shall not cause a permanent adverse effect on the free flow of water by encroaching on, blocking or restricting watercourses.
All fill material shall be of a composition suitable for the ultimate use of the fill, free of rubbish and brush, stumps, tree debris, rocks, frozen material and soft or easily compressible material.
Fill material shall be compacted sufficiently to prevent problems of erosion, and where the material is to support structures, it shall be compacted to a minimum density of 90% of modified proctor with proper moisture control.
All topsoil that is excavated from a site shall be stockpiled and used for the restoration of the site, and such stockpiles, where necessary, shall be seeded or otherwise treated to minimize the effects of erosion. Topsoil is not to be removed or sold from the site unless restoration has been completed.
Prior to, during and after site preparation and construction, an integrated drainage system shall be provided which at all times minimizes erosion, sediment, hazards of slope instability and adverse effect on neighboring property owners.
The natural drainage system shall generally be preserved in preference to modifications of this system, excepting where such modifications are necessary to reduce levels of erosion and sediment and adverse effects on neighboring property owners.
All drainage systems shall be designed to handle adequately the anticipated flows, both within the site and from the entire upstream drainage basin, so as to achieve no net increase in peak rate of runoff from the site.
Sufficient grades and drainage facilities shall be provided to prevent the ponding of water, unless such ponding is proposed by the approved site plan, in which event there shall be sufficient water flow to maintain proposed water levels and to avoid stagnation.
There shall be provided, where necessary to minimize erosion and sediment, such measures as benches, berms, terraces, diversions, temporary sediment basins and retention basins. During the course of construction, where the Stormwater Management Officer or Village Engineer determines that additional erosion control measures are needed, they shall be provided by the project owner at no cost to the Village of Walden.
Drainage systems, plantings and other erosion or sediment control devices shall be maintained as frequently as necessary to provide adequate protection against erosion and sediment and to ensure that the free flow of water is not obstructed by the accumulation of silt, debris or other material or by structural damage.
Wherever possible, clean water shall be diverted around any areas of disturbance.
For any proposed grades planned to have a slope greater than 3H:1V, the design engineer shall provide calculations documenting that the slope will be stable as designed. Slope stability should be demonstrated by two-dimensional limiting equilibrium methods such as the Bishop Simplified Method. Further, the analysis should include an evaluation of seasonal high groundwater conditions, including subsurface investigations if deemed necessary, to assure that the slope will remain stable in "worst case" conditions.
The exposure of an area by site preparation shall be kept to the shortest practical period of time prior to the construction of structures or improvements or the restoration of the exposed areas to an attractive natural condition. The developer shall initiate stabilization measures as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than seven days after the construction activity in that portion of the site has temporarily or permanently ceased; except where the initiation of stabilization measures by the seventh day after construction activity temporarily or permanently ceased is precluded by snow cover or frozen ground conditions, stabilization measures shall be initiated as soon as practicable.
The redevelopment of a site shall comply with the technical standards contained herein for water quality for the entire site, including the area proposed for redevelopment, except as noted in Subsection C below.
The redevelopment of a site shall comply with the technical standards contained herein for water quantity for any increase in the volume or rate of runoff due to the redevelopment, except as noted in Subsection C below.
A deviation from the technical and performance standards contained in this article may be permitted where an owner or developer proposing to redevelop a site demonstrates that proper sizing and installation of acceptable stormwater management practices is not feasible due to inadequate space, head or other physical constraints of the site, and that the proposed change will not cause or contribute to a significant adverse change in any water resource within that drainage basin. Inadequate space in which to locate stormwater management practices caused directly by the size or location of the proposed redevelopment shall not be considered acceptable justification to permit a deviation from the standards.
A copy of all notices of intent and all contractors' certifications required pursuant to the New York State General Permit for Stormwater Discharges from Construction Activity, Permit No. GP-02-01, for all land disturbances, development or redevelopment located within the Village of Walden shall also be filed with the Walden Planning Board.
The Village of Walden Stormwater Management Officer may require such inspections as necessary to determine compliance with this article and may either approve that portion of the work completed or notify the applicant wherein the work fails to comply with the requirements of this article and the stormwater pollution prevention plan (SWPPP), as approved. To obtain inspections, the applicant shall notify the Village of Walden Enforcement Official at least 48 hours before any of the following, as required by the Stormwater Management Officer:
Start of construction.
Installation of sediment and erosion control measures.
Completion of site clearing.

Completion of final grading.
Close of the construction season.
Completion of final landscaping.
Successful establishment of landscaping in public areas.
If any violations are found, the applicant and developer shall be notified in writing of the nature of the violation and the required corrective actions. No further work shall be conducted except for site stabilization until any violations are corrected and all work previously completed has received approval by the Stormwater Management Officer.
The Village of Walden Stormwater Management Officer is responsible for conducting inspections of stormwater management practices (SMPs). All applicants are required to submit "as-built" plans for any stormwater management practices located on site after final construction is completed. The plan must show the final design specifications for all stormwater management facilities and must be certified by a professional engineer.
Inspection programs shall be established on any reasonable basis, including but not limited to: routine inspections; random inspections; inspections based upon complaints or other notice of possible violations; inspection of drainage basins or areas identified as higher than typical sources of sediment or other contaminants or pollutants; inspections of businesses or industries of a type associated with higher than usual discharges of contaminants or pollutants or with discharges of a type which are more likely than the typical discharge to cause violations of state or federal water or sediment quality standards or the SPDES stormwater permit; and joint inspections with other agencies inspecting under environmental or safety laws. Inspections may include, but are not limited to, reviewing maintenance and repair records; sampling discharges, surface water, groundwater, and material or water in drainage control facilities; and evaluating the condition of drainage control facilities and other stormwater management practices.
The Village of Walden Stormwater Management Officer may require monitoring and reporting from entities subject to this article as are necessary to determine compliance with this article.
Where stormwater management and erosion and sediment control facilities are to be operated and maintained by the developer or by a corporation that owns or manages a commercial or industrial facility, the developer, prior to construction, may be required to provide the Village of Walden with an irrevocable letter of credit from an approved financial institution or surety to ensure proper operation and maintenance of all stormwater management and erosion control facilities both during and after construction and until the facilities are removed from operation. If the developer or landowner fails to properly operate and maintain stormwater management and erosion and sediment control facilities, the Village of Walden may draw upon the account to cover the costs of proper operation and maintenance, including engineering and inspection costs.
After the approval of the application and before the issuance of any permit, the applicant shall, when so required, file with the Village Board, as surety for the amount of the estimated cost of the project, one of the following performance guaranties:

A performance bond which shall be satisfactory to the Village Board and Village Attorney as to form, sufficiency, manner of execution, surety and period of execution.
An irrevocable letter of credit from a bank, which letter of credit shall be approved by the Village Board and Village Attorney.
The Stormwater Management Officer in approving an application submitted under § 252-21 or the Village Planning Board, whichever shall retain jurisdiction of the application, may grant a waiver of such guaranty if it deems the proposed activities to be of minor scope and to be in full compliance with the intent of this article.
The party or parties filing the performance guaranties shall certify that either upon termination of the permit or the operation, whichever may come first, the project shall be in conformity with both the approved specific requirements of the permit and the provisions of this article. In the event of default of such and violation of any other applicable laws, such performance guaranty shall be forfeited to the Village. The Village shall return to the applicant any amount that is not needed to cover the costs of restoration, administration and any other expenses incurred by the Village as a result of the applicant's default. Such performance guaranty shall continue in full force and effect until a certificate of compliance shall have been issued by the Stormwater Management Officer after such consultation with any agencies or individuals as he deems necessary to insure that all provisions of this article and of the permit have been met.
Where one or more of the requirements contained herein are not requisite in the interest of health, safety or general welfare or will provide information extraneous to the issuance of a permit, then one or more of the requirements may be waived by either the Planning Board or the Stormwater Management Officer, whichever shall have original jurisdiction.
If there is any damage due to violation of this article, or if there is any damage to adjacent properties, or if any soil, liquid or other material is caused to be deposited upon or to roll, flow or wash upon any public property, private property or right-of-way in violation of this article, the person, firm, partnership, corporation or other party responsible shall be notified and shall cause the same to be removed from such property or right-of-way within 36 hours of written notice. In the event of an incident which presents an immediate danger to the public health or safety, notice shall be given by the most expeditious means and the violation shall be immediately remedied by the party responsible for the incident or, at its discretion and when the responsible party fails to adequately remedy the incident in a reasonable time, the Village shall cause such remedy, and the cost of such remedy by the Village shall be paid to the Village by the party who failed to so remedy and shall be a debt owed to the Village.
Any person, firm or corporation, whether as owner, lessee, principal, agent, employee or otherwise, violating any of the provisions of this article shall be guilty of a violation, which shall be punishable by a fine of not less than $200 nor more than $350 or imprisonment for a period not to exceed six months, or both, for a conviction of the first offense; for conviction of a second offense, both of which were committed within a period of five years, punishable by a fine of 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.
Every day that a violation of any of the provisions of this chapter continues after written notice shall have been served upon the owner or his agent, either personally or by registered mail addressed to such person at his last known address, or after three days of having posted notice on the property on which the violation has occurred, shall constitute a separate violation.
The Stormwater Management Officer, in the administration of his duties contained herein, shall have the authority to issue stop-work orders and appearance tickets for violations of this article. The Code Enforcement Officer shall also have the authority to enforce the provisions of this article.
Where this article imposes greater restrictions than are imposed by the provision of any law, ordinance, regulation or private agreement, this article shall control.
