The purpose of this article is to provide for the health, safety, and general welfare of the citizens and businesses of the City of New Castle (the "City") through the regulation of nonstormwater discharges to the storm drain system to the maximum extent practicable as required by federal and state law. This article establishes methods for controlling the discharge of pollutants into the municipal separate storm sewer system (MS4) in order to comply with requirements of the City's National Pollutant Discharge Elimination System (NPDES) permit. The objectives of this article are to:
Regulate the discharge of pollutants to the municipal separate storm sewer system (MS4) by any user.
Prohibit illicit discharges and connections to the municipal separate storm sewer system.
Establish legal authority to carry out all inspection, surveillance, monitoring, and enforcement procedures necessary to ensure compliance with this article.

This article shall apply to all water entering the MS4 generated on any developed and undeveloped lands unless explicitly exempted by an authorized enforcement agency.
City Code Enforcement Officers shall administer, implement, and enforce the provisions of this article. Any powers granted or duties imposed upon such authorized enforcement personnel may be delegated in writing by the City Administrator to persons or entities acting in the beneficial interest of or in the employ of the City.
The standards set forth herein and promulgated pursuant to this article are minimum standards; therefore, this article does not intend nor imply that compliance by any person will ensure that there will be no contamination, pollution, nor unauthorized discharge of pollutants.
Prohibition of illicit discharges.
No person shall discharge or cause to be discharged into the MS4 or watercourses any materials, including but not limited to pollutants or waters containing any pollutants that cause or contribute to a violation of applicable water quality standards, other than stormwater.
The commencement, conduct or continuance of any illicit discharge to the MS4 is prohibited except as described as follows:
Water line flushing;
Diverted stream flows;
Uncontaminated groundwater infiltration to separate storm sewers;
Uncontaminated pumped groundwater;
Discharges from potable water sources;
Water from crawl space pumps;
Individual residential vehicle washing;
Flows from riparian habitats and wetlands;
Dechlorinated swimming pool discharges; and
Discharges or flows from emergency firefighting activities; Additionally.
Discharges specified in writing by the authorized enforcement agency as being necessary to protect public health and safety; and
Dye testing is an allowable discharge, but requires a verbal notification to the authorized enforcement agency prior to the time of the test.
The prohibition shall not apply to any nonstormwater discharge permitted under an NPDES permit, waiver, or waste discharge order issued to the discharger and administered under the authority of the United States Environmental Protection Agency, 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 article if the person connects a line conveying sewage to the MS4, or allows such a connection to continue.
Suspension due to illicit discharges in emergency situations. The Code Enforcement 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, or to the health or welfare of persons, or to the MS4 or waters of the United States. If the violator fails to comply with a suspension order issued in an emergency, the authorized enforcement agency may take such steps as deemed necessary to prevent or minimize damage to the MS4 or waters of the United States, or to minimize danger to persons.
Suspension due to the detection of illicit discharge.
Any person discharging to the MS4 in violation of this article may have his or her MS4 access terminated if such termination would abate or reduce an illicit discharge. The authorized enforcement agency will notify a violator of the proposed termination of its MS4 access. The violator may petition the authorized enforcement agency for a reconsideration and hearing.
A person commits an offense if the person reinstates MS4 access to premises terminated pursuant to this section, without the prior approval of the authorized enforcement agency.
Any person subject to an industrial or a NPDES General Permit for stormwater Discharges Associated with Construction Activity shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the Code Enforcement Officer prior to the allowing of discharges to the MS4.
Applicability. This section applies to all facilities that have stormwater discharges associated with industrial activity, including construction activity.
Access to facilities.
The Code Enforcement Officers 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 representatives of the authorized enforcement agency.
Facility operators shall allow the Code Enforcement Officers ready access to all parts of the premises for the purposes of inspection, sampling, examination and copying of records that must be kept under the conditions of an NPDES permit to discharge stormwater, and the performance of any additional duties as defined by state and federal law.
The City shall have the right to set up on any permitted facility such devices as are necessary in the opinion of the authorized enforcement agency to conduct monitoring and/or sampling of the facility's stormwater discharge.
The City has the right to require the discharger to install monitoring equipment as necessary. 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.
Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the operator at the written or oral request of the City and shall not be replaced. The costs of clearing such access shall be borne by the operator.
Unreasonable delays in allowing the City access to a permitted facility is a violation of a stormwater discharge permit and of this article. A person who is the operator of a facility with a NPDES permit to discharge stormwater associated with industrial activity commits an offense if the person denies the authorized enforcement agency reasonable access to the permitted facility for the purpose of conducting any activity authorized or required by this article.
If the City has been refused access to any part of the premises from which stormwater is discharged, and the Code Enforcement Officer 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, or to protect the overall public health, safety, and welfare of the community, then the authorized enforcement agency may seek issuance of a search warrant from any court of competent jurisdiction.
The City requires best management practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of stormwater, the MS4, or waters of the United States. The owner or operator of a commercial or industrial establishment shall provide, at its own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the MS4 or watercourses through the use of these structural and nonstructural BMPs. Further, any person responsible for a property or premises which is, or may be, the source of an illicit discharge may be required to implement, at said person's expense, additional structural and nonstructural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system. Compliance with all terms and conditions of a valid NPDES permit authorizing the discharge of stormwater associated with industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this section. These BMPs shall be part of a stormwater pollution prevention plan (SWPP) as necessary for compliance with requirements of the NPDES permit.
Every person owning or occupying property through which a watercourse passes, including such person's lessee, shall keep and maintain that part of the watercourse within the property free of trash, debris, excessive vegetation, and other obstacles that would pollute, contaminate, or significantly retard the flow of water through the watercourse. In addition, the owner, occupant or lessee shall maintain existing privately owned structures within or adjacent to a watercourse, so that such structures will not become a hazard to the use, function, or physical integrity of the watercourse.
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 illicit discharges or pollutants discharging into stormwater, the MS4, or waters of the United States, 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 authorized enforcement agency in person or by phone or facsimile no later than the next business day. Notifications in person or by phone shall be confirmed by written notice addressed and mailed to the City of New Castle within three business days of the phone 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 five years.
Notice of violation. Whenever the City finds that a person has violated a prohibition or failed to meet a requirement of this article, the authorized enforcement agency may order compliance by written notice of violation to the responsible person. Such notice may require without limitation:
The performance of monitoring, analyses, and reporting;
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;
Payment of a fine to cover administrative and remediation costs; 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.
The City at its discretion may file charges in Justice of the Peace (JP) Court for violating this article of the City Code. If needed, the City will contact DNREC's Office of Community Services' Environmental Crimes Unit. All of DNREC's environmental officers are certified police officers with full police powers.
Any person receiving a notice of violation may appeal the determination of the authorized enforcement agency to the City Board of Adjustment which shall have jurisdiction to hear and decide such appeals. The notice of appeal must be received by the City within 10 calendar days from the date of the notice of violation. Hearing on the appeal before the appropriate authority or his/her designee shall take place within 15 days from the date of receipt of the notice of appeal. The decision of the Board of Adjustment shall be final unless appealed to the Delaware Superior Court.
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 15 days of the decision of the Board of Adjustment upholding the decision of the authorized enforcement agency, then representatives of the authorized enforcement agency shall enter upon the subject private property and are authorized to take any and all measures necessary to abate the violation and/or restore the property. It shall be unlawful for any person, owner, agent or person in possession of any premises to refuse to allow the government agency or designated contractor to enter upon the premises for the purposes set forth above.
Within 10 days after abatement of the violation, the owner of the property will be notified of the cost of abatement, including legal and administrative costs. The property owner may file a written protest with the City Administrator objecting to the amount of the assessment within 10 calendar days of the date of the notice. The City Administrator shall review the assessment and the grounds for the protest and shall have authority to adjust the assessment only if he determines that there has been an error in calculating the cost of abatement or legal and administrative costs associated therewith. If the amount due is not paid within a timely manner as determined by the decision of the City Administrator or by the expiration of the time in which to file an appeal, the charges shall become a special assessment against the property and shall constitute a lien on the property for the amount of the assessment and collectible by the City in the same manner as delinquent real estate taxes due the City. Any person violating any of the provisions of this article shall become liable to the City by reason of such violation. The liability shall be paid in not more than 12 equal payments and shall also include twelve-percent-per-annum interest on the total amount due.
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 authorized enforcement agency 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 lieu of enforcement proceedings, penalties, and remedies authorized by this article, the authorized enforcement agency may impose upon a violator alternative compensatory action, such as storm drain stenciling, attendance at compliance workshops, creek cleanup, etc.
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.
Any person who has violated or continues to violate this article shall be liable to criminal prosecution to the fullest extent of the law, and shall be subject to a criminal penalty of $200 per violation per day and/or imprisonment for a period of time not to exceed 120 days. The authorized enforcement agency may recover all attorneys' fees, court costs and other expenses associated with enforcement of any provision of this article, including sampling and monitoring expenses, whether or not civil or criminal proceedings are required to compel compliance or address violations.
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.
