Stormwater Code: Excerpts from Oyster Bay, New York Municipal Code
Under regulations implemented by the Federal Clean Water Act, the United States Environmental Protection Agency (USEPA) and the New York State Department of Environmental Conservation (NYSDEC) required municipalities, including the Town of Oyster Bay, to implement programs and practices that would help minimize storm water pollution.
In 2003, the Town of Oyster Bay was one of the first municipalities in New York to initiate its Storm Water Management Program (SWMP). The goal of the Town’s SWMP is to reduce the impacts of storm water runoff thereby improving water quality, enhancing the recreational enjoyment of waterways, preventing beach closures and ensuring that seafood is safe for human consumption. This SWMP is a permitted program (called a Storm Water Discharge Permit) implemented by the NYSDEC as delegated by the USEPA.
The Town’s SWMP includes the following six mandated program areas:
- Public education and outreach about storm water impacts
- Public involvement and participation
- Illicit discharge detection and elimination
- Construction site storm water runoff control
- Post-construction storm water management
- Pollution prevention and good housekeeping for municipal operations
The Town maintains a storm water drainage system that consists of the grate or curb openings that you see along Town roads and in parking lots, which are called storm drains or catch basins. These catch basins collect the storm water runoff from the streets transmitting it through a network of pipes to numerous storm water outfalls throughout the Town. These outfalls can empty into recharge basins inland or surface waters along the Town’s north and south shorelines. Were the Town not to have this storm drain system, then streets and property could flood every time it rains or freeze during the winter storms.
The Town of Oyster Bay has set up stormwater standards in order to establish minimum stormwater requirements and controls to protect and safeguard the general health, safety and welfare of the public residing within the Town. The Town of Oyster Bay has also enacted stormwater ordinances in order to provide for the health, safety, and general welfare of the citizens of the Town of Oyster Bay through the regulation of non-stormwater discharges to the municipal separate storm sewer system (MS4) to the maximum extent practicable as required by federal and state law.
Maintenance, Inspection & Repair of Stormwater Facilities
Maintenance easement(s)
Prior to the issuance of any approval that has a stormwater management facility as one of the requirements, the applicant, or developer, must execute a maintenance easement agreement that shall be binding on all subsequent landowners served by the stormwater management facility. The easement shall provide for access to the facility at reasonable times for periodic inspection by the Town of Oyster Bay to ensure that the facility is maintained in proper working condition to meet design standards and any other provisions established by this chapter. The easement shall be recorded by the grantor in the Office of the Nassau County Clerk after approval by the counsel for the Town of Oyster Bay.
Maintenance after construction
The owner or operator of permanent stormwater management practices installed in accordance with this chapter shall ensure that they are maintained and operated to achieve the goals of this chapter. Proper operation and maintenance also includes, as a minimum, the following:
- A preventative/corrective maintenance program for all critical facilities and systems of treatment and control (or related appurtenances) which are installed or used by the owner or operator to achieve the goals of this chapter.
- Written procedures for operation and maintenance and training new personnel.
- Discharges from the SMPs shall not exceed design criteria or cause or contribute to water quality standard violations as defined below:
- Any land development activity shall not cause an increase in turbidity that will result in substantial visible contrast to natural conditions in the surface waters of the State of New York.
Maintenance agreements
The Town of Oyster Bay shall approve a formal maintenance agreement for stormwater management facilities binding on all subsequent landowners and recorded in the Nassau County Clerk as a deed restriction on the property prior to final plan approval. The maintenance agreement shall be consistent with the terms and conditions of Schedule B of this chapter, entitled Sample Stormwater Control Facility Maintenance Agreement. (Note: Schedule B, Sample Stormwater Control Facility Maintenance Agreement, is included at the end of this chapter.) The Town of Oyster Bay, in lieu of a maintenance agreement, and at its sole discretion, may accept dedication of any existing or future stormwater management facility, provided such facility meets all of the requirements of this chapter and includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection and regular maintenance.
Prohibition against Activities Contaminating Stormwater
Activities that are subject to the requirements of this section are those types of activities that:
- Cause or contribute to a violation of the municipality’s MS4 SPDES permit.
- Cause or contribute to the municipality being subject to the following special conditions:
- Discharge compliance with water quality standards. The condition that applies where a municipality has been notified that the discharge of stormwater authorized under its 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.
- 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.
- Total maximum daily load (TMDL) 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 waterbody 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.
- The condition in the municipality’s MS4 permit that applies if a TMDL is approved in the future by the EPA for any waterbody 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.
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.
Discharge & Connection Prohibitions
Prohibition of illegal discharges
No person shall discharge or cause to be discharged into the MS4 any materials other than stormwater except as provided in the below subsection (1). The commencement, conduct or continuance of any illegal discharge to the MS4 is prohibited except as described as follows:
- The following discharges are exempt from discharge prohibitions established by this chapter, unless the Department or the municipality has determined them to be substantial contributors of pollutants: water line flushing or other potable water sources, landscape irrigation or lawn watering, existing diverted stream flows, rising groundwater, uncontaminated groundwater infiltration to storm drains, uncontaminated pumped groundwater, foundation or footing drains, crawl space or basement sump pumps, air conditioning condensate, irrigation water, springs, water from individual residential car washing, natural riparian habitat or wetland flows, dechlorinated swimming pool discharges, residential street wash water, water from fire-fighting activities, and any other water source not containing pollutants. Such exempt discharges shall be made in accordance with an appropriate plan for reducing pollutants.
- Discharges approved in writing by the Stormwater Management Officer (SMO) to protect life or property from imminent harm or damage, provided that such approval shall not be construed to constitute compliance with other applicable laws and requirements, and further provided that such discharges may be permitted for a specified time period and under such conditions as the SMO may deem appropriate to protect such life and property while reasonably maintaining the purpose and intent of this chapter.
- Dye testing in compliance with applicable state and local laws is an allowable discharge, but requires a verbal notification to the SMO prior to the time of the test.
- The prohibition shall not apply to any discharge permitted under a SPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of the Department, provided that the discharger is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations, and provided that written approval has been granted for any discharge to the MS4.
Prohibition of illicit connections
The construction, use, maintenance or continued existence of illicit connections to the MS4 is prohibited.
This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection.
A person is considered to be in violation of this chapter if the person connects a line conveying sewage to the municipality’s MS4, or allows such a connection to continue.
Use of Best Management Practices Required
Where the SMO has identified illicit discharges or activities contaminating stormwater, the municipality may require implementation of best management practices (BMPs) to control those illicit discharges and activities.
The owner or operator of a commercial or industrial establishment shall provide, at his/her own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the MS4 through the use of structural and nonstructural BMPs.
Any person responsible for a property or premise, which is or may be the source of an illicit discharge or an activity contaminating stormwater 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.
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.
Enforcement
Notice of violation
When the municipality’s SMO finds that a person has violated a prohibition or failed to meet a requirement of this chapter, 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 chapter 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 chapter 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.
Corrective Measures after Issuance of Notice of Violation
If the violation has not been corrected pursuant to the requirements set forth in the notice of violation, or, 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.
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.
Violations Deemed Public Nuisance
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 chapter 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.

Frequently Asked Questions
What is post-construction stormwater management, and does it apply to my property in Oyster Bay?
Post-construction stormwater management is one of the six mandated areas of Oyster Bay’s Storm Water Management Program, permitted by the New York State Department of Environmental Conservation, and it covers the ongoing responsibility to maintain permanent stormwater practices on your property. If your property in Oyster Bay has a stormwater facility installed under an approved plan, keeping it functioning is a continuing obligation, not a one-time construction requirement. AQUALIS provides full post-construction stormwater management for property owners across Oyster Bay, so facilities stay compliant well after a project is finished.
What ongoing maintenance program does Oyster Bay require for stormwater facilities?
Oyster Bay requires owners or operators to maintain permanent stormwater practices through a preventative and corrective maintenance program for treatment systems, supported by written operational procedures and personnel training, all aimed at meeting the facility’s design criteria and state water quality standards. This is a formal, documented commitment, not just occasional or reactive upkeep. AQUALIS develops and manages these preventive and corrective maintenance programs for Oyster Bay property owners, keeping documentation aligned with the actual maintenance work performed.
What happens if my stormwater facility in Oyster Bay is not maintained properly?
If a stormwater facility in Oyster Bay is not maintained according to its design criteria, or if an illegal discharge is identified, the Town issues a written notice of violation specifying a remediation deadline. Penalties range from $350 for a first offense to $700 to $1,000 for subsequent violations within five years, with potential imprisonment for repeat violations. AQUALIS provides non-compliance resolution for Oyster Bay property owners, correcting maintenance issues and notice of violation matters before they escalate further.
Where can property owners in Oyster Bay get help with post-construction stormwater compliance?
Post-construction stormwater compliance in Oyster Bay involves a recorded maintenance easement agreement, a documented preventive and corrective maintenance program, broad SMO inspection authority, and restrictions on what can enter the MS4. Managing all of this without dedicated stormwater staff is difficult for most property owners. AQUALIS offers complete post-construction stormwater management for Oyster Bay property owners, covering maintenance, inspections, and non-compliance resolution, so owners can meet the Town’s requirements without managing the process themselves.
