If such charge is not paid within ninety days from the date of entry, it shall be the duty of the city collector to collect and receive interest thereon at the rate of seven percent per annum, to be calculated to the date of payment from the date of entry. Such charge and the interest thereon shall continue to be, until paid, a lien on the premises served by such curb-to-sewer connection. Such charge and interest shall be calculated and the lien thereof may be foreclosed in the manner provided by law for the collection and foreclosure of the lien of taxes, sewer rents, sewer surcharges and water rents due and payable to the city, and the provisions of the code applicable to the collection and foreclosure of the lien of such taxes, sewer rents, sewer surcharges and water rents shall apply to such charge and the interest thereon and the lien thereof. Such lien shall be prior and superior to every other lien or claim except the lien of an existing tax, water rent, sewer rent, sewer surcharge, or local assessment. The provisions of section 11-307 of the code applicable to the payment of assessments shall also apply to the charge established pursuant to this section. c. Nothing contained in this section shall affect, impair or diminish the duty, obligation and responsibility of the owner of real property connected with the sewer system at his or her own cost and expense: (1) to maintain any curb-to-sewer connection serving such real property; and (2) to repair, reconstruct or replace such curb-to-sewer connection except when the necessity for such repair, reconstruction or replacement is caused by the reconstruction or replacement of the sewer or by any other construction work performed by the city. d. The cost of constructing a curb-to-sewer connection in connection with the construction, reconstruction, or replacement of a sewer duly authorized on or after July first, nineteen hundred sixty-two, shall be paid initially out of the real property fund upon the authorization of the board of estimate. All sums received or collected in reimbursement of such cost pursuant to this section, including interest and penalties thereon, shall be paid into the real property fund. This subdivision shall not apply to or affect the manner of financing the cost of repairing, reconstructing or replacing a curb-to-sewer connection when such repair, reconstruction or replacement is necessary because of the reconstruction or replacement of the sewer or because of any other construction work performed by the city.

NYC Admin. Code § 24-514 Sewer rents.

§ 24-514 Sewer rents. a. Sewer system, defined. As used in this section the term "sewer system" shall mean and include the sewers, manholes, intercepting sewers, sewage pumping, treatment and disposal works, and any other plants, works or equipment and accessories within the city, which are used or useful in connection with the collection, treatment or disposal of sewage and waste, and which are owned, operated or maintained by the city as part of the public sewer system. b. Imposition and computation of sewer rent or charge. 1. In addition to any other fees or charges provided by law, the owner of any parcel of real property connected with the sewer system, including but not limited to real property connected with the sewer system by means of a private sewer or drain emptying into the sewer system, shall pay a sewer rent or charge for the use of the sewer system. Such rent or charge shall be based on the water supplied to any such real property as measured by the amount charged for such water, except as otherwise provided by this section. Such rent or charge shall be computed by the commissioner of environmental protection in accordance with the provisions of this section. 2. For any such property supplied with water from the municipal water supply system the sewer rent or charge shall be equal in amount to sixty percent of the charges for water supplied to such property from such system. 3. For any such property supplied with water by a private water company, the commissioner of environmental protection shall, by rule and regulation, subject to the approval of the board of estimate, fix the fraction of the charges for such water, which shall constitute the sewer rent for such property, so that the sewer rent or charge for such property shall, as nearly as possible, be equivalent to the sewer rent or charge imposed under paragraph two of this subdivision for property supplied with water from the municipal water supply system. 4. If any such property is supplied with river water or water from private wells, the sewer rent or charge for such property shall be equal in amount to sixty percent of the amount that would be charged for the quantity of water supplied from such sources if such water were supplied by the city at the rates charged for water supplied to metered premises. The commissioner of environmental protection shall estimate the quantity of water supplied from such sources and shall compute the sewer rent or charge, on the basis of such estimated quantity, in accordance with the provisions of this paragraph. However, if a water meter, approved by the commissioner of environmental protection, has been or shall be installed by the owner or occupant of the premises to measure the quantity of water supplied from such sources, the quantity of water measured by such meter shall constitute the basis for computing the sewer rent or charge in accordance with the provisions of this paragraph. In the event that such property supplied with river water or water from private wells is also supplied with water from the municipal water supply system or by a private water company, the sewer rent or charge for such property shall consist of the rent or charge computed pursuant to this paragraph and the rent or charges computed in accordance with paragraph two or three of this subdivision as the case may be. 5. The commissioner of environmental protection shall have the power to promulgate rules and regulations, subject to the approval of the board of estimate, prescribing reasonable sewer rents or charges for any such property which is used for an industrial or commercial purpose of such a nature that water supplied to it cannot be entirely discharged into the sewer system. The sewer rent or charges prescribed pursuant to this paragraph shall be based, as far as practicable, upon the amount of sewage discharged into the sewer system as estimated by the commissioner of environmental protection, or where an estimate of such amount is impracticable, upon any other basis bearing a reasonable relationship to the amount of sewage discharged into the sewer system. c. Additional rule making powers. The commissioner of environmental protection shall have the power to make such additional rules and regulations as may be necessary to carry out the provisions of this section. Such rules and regulations shall be subject to approval by the board of estimate. d. Cooperation by private persons, water companies, and public agencies. The commissioner of environmental protection may require every person who owns or occupies real property within the city, every private water company supplying water to property within the city, and all municipal agencies, officers, and employees to furnish him or her with such information as may be necessary to carry out the provisions of this section. Every such person, water company, or municipal agency, officer, or employee shall cooperate with the commissioner of environmental protection in carrying out the provisions of this section and shall comply with all rules and regulations promulgated pursuant to this section. Such commissioner shall have the power to hold such hearings and to subpoena such witnesses and direct the production of such books and papers as may be necessary to carry out the provisions of this section. e. Exemptions from sewer rents or charges. Any real property which is entitled to an exemption from the payment of water rents or charges shall also be exempt from payment of the sewer rents or charges imposed hereunder. f. Payment and enforcement of sewer rents or charges. All sewer rents or charges imposed hereunder shall be due and payable at the times and in the manner provided in chapters three and four of title eleven of the code. Such rents or charges shall constitute a lien upon the real property served by the sewer system and such lien shall be prior and superior to every other lien or claim except the lien of an existing tax, water rent or local assessment. Such rents or charges shall be collected and the liens thereof may be foreclosed in the manner provided in chapters three and four of title eleven of this code. g. Sewer fund. The revenues derived from the sewer rentals imposed hereunder, including penalties and interest thereon, shall be kept in a separate and distinct fund to be known as the sewer fund. Such fund shall be used for the payment of the cost of the management, maintenance, operation and repair of the sewer system, the cost of administering and enforcing the provisions of this section and the cost of collection of the sewer rents or charges imposed pursuant to the provisions of this section, and any surplus in such fund shall be used for the payment of the interest and amortization on any debt which has been or shall be incurred for the construction of intercepting sewers and sewage treatment and disposal works, and for the enlargement, replacement, or addition of intercepting sewers or sewage treatment works. However, such funds shall not be used for the extension of sewers to serve unsewered areas.

Imposition and computation of sewer surcharge. 1. In addition to any other fees, charges or sewer rents provided by section 24-514 of the code or any other law, the owner of any parcel of real property connected with the sewer system, including but not limited to real property connected with the sewer system by means of a private sewer or drain emptying into the sewer system, shall pay a surcharge for the use of the sewer system for discharging any sewage, industrial waste or other waste, accepted for admission thereto in which the characteristics resulting from pollutants contained therein exceed the maximum values of such characteristics in receivable industrial waste as defined in subdivision a of this section and the rules and regulations of the commissioner adopted pursuant to this section. 2. i. Such charge shall be computed by the commissioner in accordance with the following formula: The amount of the surcharge shall equal the product of: (A) the cost per pound of removing pollutants from the sewage in the sewer system, (B) a conversion factor and (C) the volume of sewage, industrial waste or other wastes discharged into the sewer system, multiplied by the sum of (A) the average concentration in parts per million by weight of suspended solids for sewage, industrial waste or other wastes discharged into the sewer system, in excess of three hundred fifty parts per million, and (B) the average concentration in parts per million by weight of the biochemical oxygen demand for sewage, industrial waste, or other wastes discharged into the sewer system in excess of three hundred parts per million. Such formula expressed in symbols shall be as follows: Ds = C × F × V × [(S.S. - 350) + (B.O.D. - 300)] where Ds = amount of surcharge, in dollars; C = cost per pound (in dollars) of removing pollutants from the sewage discharged into the sewer system expressed to the nearest tenth of a cent; F = 62.41,000,000, i.e., the factor for converting parts per million by weight to pounds per million cubic feet; V = volume, in cubic feet of sewage, industrial waste or other wastes discharged from such premises into the sewer system; S.S. = parts per million by weight of suspended solids in sewage, industrial waste or other wastes discharged from such premises into the sewer system; 350 = maximum parts per million by weight of S.S. allowable in receivable industrial waste; B.O.D. = parts per million by weight of B.O.D. in the sewage, industrial waste or other wastes discharged from such premises into the sewer system; 300 = maximum parts per million by weight of B.O.D. allowable in receivable industrial waste. ii. In applying such formula the commissioner may use, as the figure representing the number of cubic feet of sewage discharged into the sewer system, (A) the amount of water supplied to the premises by the city or a private water company as shown upon the water meter if the premises are metered, or (B) if the premises are supplied with river water or water from private wells, the amount of water supplied from such sources as estimated by the commissioner, pursuant to paragraph four of subdivision b of section 24-514 of this chapter, or (C) if such premises are used for an industrial or commercial purpose of such a nature that the water supplied to the premises cannot be entirely discharged into the sewer system, the estimate of the amount of sewage discharged into the sewer system made by the commissioner, pursuant to the provisions of paragraph five of subdivision b of section 24-514 of the code, or (D) the number of cubic feet of sewage discharged into the sewer system as determined by measurements and samples taken at a manhole installed by the owner of the property served by the sewer system at his or her own expense in accordance with the terms and conditions of the permit issued by the commissioner pursuant to this method, or (E) a figure determined by the commissioner by any combination of the foregoing or by any other equitable method. c. 1. The commissioner may require that a permit be obtained for the discharge whether direct or indirect into the sewer system or into any private sewer or drain emptying into the sewer system, of sewage, industrial wastes or other wastes, the characteristics of which do not conform to the characteristics prescribed for normal sewage in accordance with the provisions of paragraph ten of subdivision a of this section or for the discharge of any toxic substance or any other objectionable material or substance specified by the rules and regulations promulgated pursuant to subdivision e of this section. The commissioner, in his or her discretion, may require a permit for all such discharges or for any class or category of such discharges. Any discharge pursuant to such permit shall be upon such terms and conditions as may be established by the commissioner in the issuance of such permit. Such terms and conditions may include requirements of a limitation upon the volume of sewage and the rate of flow permitted from the premises which are the subject of the permit, the installation and maintenance by the permittee at his or her own expense of facilities or equipment for intermittent or continuous measurement of sewage, industrial waste or other wastes discharged into the sewer system from such premises, the installation and maintenance by the permittee, at his or her own expense, of detention tanks or other facilities or equipment for reducing the maximum rates of discharge of sewage to such percentage of the twenty-four hour rate as may be required by the commissioner, the installation and maintenance by the permittee, at his or her own expense of such preliminary treatment facilities as may be required by the commissioner, the installation and maintenance by the permittee, at his or her own expense, of a suitable control manhole in the house sewer, if any, carrying such sewage; the submission to and approval by the commissioner of the plans for any of the facilities or equipment required to be installed and maintained by the permittee pursuant to such terms and conditions; and such other terms and conditions as may be necessary to protect the sewer system and carry out the provisions of this section. Such terms and conditions may also provide that subsequent to the commencement of operation of any preliminary treatment facilities required by the commissioner, periodic reports shall be made by the permittee to the commissioner, setting forth adequate data upon which the acceptability of the sewage, industrial waste or other wastes, after treatment, may be determined. A violation by the permittee of any term or condition of the permit shall constitute cause for revocation or suspension of the permit. 2. Whenever required to carry out the provisions of this section and the regulations promulgated pursuant to this section, the commissioner may require any person discharging directly or indirectly into the sewer system or into any private sewer or drain emptying into the sewer system to (i) establish and maintain such records, (ii) make such reports, (iii) install, use and maintain such monitoring equipment or methods (including where appropriate biological monitoring methods) (iv) sample such effluents (in accordance with such methods, at such locations, at such intervals and in such manner as the commissioner shall prescribe) and (v) provide such other information as he or she may reasonably require. 3. Any person discharging directly or indirectly into the sewer system or into any private sewer or drain emptying into the sewer system, shall be deemed to have consented and agreed that the commissioner or his or her deputies or such other officers or employees as are authorized by the commissioner may enter on the premises from which such discharge is emitted or in which any records required to be maintained under paragraph two are located and may at reasonable times have access to and copy any records, inspect any monitoring equipment or method required under paragraph two and sample any effluents discharged from the premises to the sewer system. 4. It shall be unlawful to make any false statement, representation or certification in any application, record, report, plan, or other document filed with or required to be maintained by the commissioner or to falsify, tamper with or knowingly render inaccurate any monitoring device or method required to be maintained by the commissioner. d. Sampling of industrial wastes. Whenever sewage, industrial waste or other waste which has characteristics which do not conform to the characteristics prescribed for normal sewage or receivable industrial waste pursuant to paragraphs ten and eleven of subdivision a of this section, or which contains toxic substances or other material or substance excluded from the sewer system by the commissioner pursuant to this section is discharged into the sewer system from any premises, the commissioner shall have the power to take such samples and tests as may be necessary to determine the nature and concentration of such wastes, and shall have the power to reassess his or her findings by taking such additional samples or tests at any time or by periodic rechecks without notice to the owner or person discharging such wastes. Samples shall be taken and flow measurements made, whenever possible, at a common manhole into which all flows of sewage, industrial waste or other waste from such premises are combined. Such manhole shall be constructed by the owner of such premises, at his or her own expense, when directed by order of the commissioner. Whenever the installation of such a manhole is impossible or impracticable, the owner of such premises shall construct and maintain at his or her own expense, any additional manholes required by order of the commissioner, for accurate measurement of all flow of sewage, industrial waste or other wastes discharged from such premises into the sewer system. Failure to comply with an order of the commissioner issued pursuant to this subdivision may subject the premises to temporary termination of water supply in accordance with the provisions of section 11-314 of the code. e. Rules and regulations. 1. The commissioner shall have the power to promulgate rules and regulations: (a) identifying toxic substances and regulating, restricting or prohibiting the discharge of such substances into the sewer system in amounts or concentrations which may cause any of the adverse effects described in paragraph thirteen of subdivision a of this section; (b) regulating, restricting or prohibiting the discharge into the sewer system of any material or substance which is or may be detrimental or destructive to the sewer system or the treatment processes thereof or to the public health or welfare; (c) specifying the characteristics and the minimum and maximum amounts thereof, in addition to those specified in paragraph eleven of subdivision a hereof, for receivable industrial waste; (d) such additional rules and regulations as may be necessary to protect personnel, the sewer system and the treatment process thereof and the receiving waters; and (e) regulating the amount and concentration of substances contained in industrial waste discharged directly or indirectly into the sewer system to achieve compliance with effluent limitations imposed upon city discharges to receiving waters by federal or state law or regulation or a discharge permit issued pursuant thereto. 2. The commissioner shall by rule or regulation adopt the standards, prohibitions and requirements promulgated under the federal water pollution control act, commonly referred to as the clean water act, as amended, except where such standards, prohibitions and requirements are less stringent than those which are established by the commissioner pursuant to paragraph one or three of this subdivision. 3. Notwithstanding any inconsistent provision of paragraphs one and two of this subdivision, the commissioner may order any person discharging a toxic substance directly or indirectly into the sewer system or into any private sewer or drain emptying into the sewer system to reduce the amount or concentration of such toxic substance to a level which the commissioner determines to be economically achievable by the discharger notwithstanding that such level is lower than that which is prescribed in the regulations adopted pursuant to paragraph one or two or that the discharge is not regulated under such provision. Within twenty days after the issuance of an order by the commissioner, any person affected by such order may request a hearing before the commissioner. The commissioner may suspend, revoke or modify the order. f. Cooperation by private persons, water companies and public agencies. The commissioner may require every person who owns or occupies real property within the city and every private water company supplying water to property within the city, to furnish him or her with such information as may be necessary to carry out the provisions of this section. The commissioner shall have the power to hold hearings and to subpoena any such persons or company, or any officer, employee or agent of any such company, and direct the production of books and papers in order to carry out the provisions of this section. Every such person, water company or public official or municipal agency, officer or employee shall cooperate with the commissioner in carrying out the provisions of this section and shall comply with all rules and regulations promulgated pursuant to this section. g. Payment and enforcement of sewer surcharges. All surcharges imposed hereunder shall be due and payable at the times and in the manner provided in chapters three and four of title eleven of the code with respect to the payment of sewer rents based upon the metered supply of water. Such sewer surcharges shall constitute a lien upon the real property served by the sewage system and such lien shall be prior and superior to every other lien or claim except the lien of an existing tax, water rent, sewer rent or local assessment. Such sewer surcharges shall be collected and the liens thereof may be foreclosed in the manner provided in chapters three and four of title eleven of the code. The revenues derived from the sewer surcharges imposed hereunder, including penalties and interest thereon shall be paid into the sewer fund established pursuant to section 24-514 of the code and shall be used in the manner and for the purposes provided therein.

If service of the order cannot be made personally because such person cannot be located at such time then service may be made by delivering a copy to a person of suitable age and discretion at the residence or place of business of the person sought to be served. If service cannot be made personally or by such delivery to a person of suitable age and discretion because of inability to locate or to obtain the name or address of such person at such time, service may be made by conspicuously posting a copy of such order upon the property to which it relates and mailing the order to the most recent residential or business address of record of the person sought to be served. The posting and mailing of such order shall be sufficient notice of such order to all persons having a duty in relation thereto under the provisions of this subdivision. 3. If the order is not complied with or so far complied with as such commissioner may regard as reasonable, within the time specified therein such commissioner may act to halt or prevent such discharge by: i. sealing, blocking or otherwise inactivating any equipment, facility, or device; ii. terminating the water supply to the premises; iii. sealing, blocking or otherwise inactivating any private sewer or drain emptying directly or indirectly into the sewer system; or iv. any other means or method that is reasonable under the circumstances. For such purpose, in accordance with applicable law, the commissioner of environmental protection or his or her deputies or such other officers or employees as are designated by the commissioner may enter on any public or private property. 4. Any person affected by such an order may make written application to the environmental control board within the office of administrative trials and hearings for a hearing.

The board may suspend, modify or terminate such order. c. [Reserved.] d. Environmental control board cease and desist orders. 1. In the case of any continued or knowing violation of any of the provisions of subdivision b or b-1 of section 1403 of the charter or sections 24-504 through 24-523 of this chapter or any order or rule issued by the environmental control board within the office of administrative trials and hearings or commissioner of environmental protection pursuant to such provisions or subdivision a of this section in furtherance of such provisions or of the conditions of any permit issued pursuant to such provisions or where the board finds that the violation of any of such provisions or of the conditions of any such permit presents or may present a danger to the environment or threatens to interfere with the operation of the sewer system, the board after notice and the opportunity for a hearing in accordance with the rules of such board within such office, may issue a cease and desist order requiring any person who owns, leases, operates, controls or supervises any building, structure, facility or installation to cease and desist from any activity or process which causes or is conducted so as to cause such violation within the time specified in such order. 2. Such order may provide that if the order is not complied with or so far complied with as the commissioner of environmental protection may regard as reasonable within the time specified therein, such commissioner may take such action as shall be specified therein, including but not limited to: i. sealing, blocking or inactivating any equipment, facility or device; ii. terminating the water supply to the premises; iii. sealing, blocking or inactivating any private sewer or drain emptying directly or indirectly into the sewer system; or iv. any other means or method that is reasonable under the circumstances. For such purpose, in accordance with applicable law, the commissioner of environmental protection or his or her deputies or such other officers or employees as are designated by such commissioner may enter on any public or private property. e. Action by corporation counsel. If the respondent fails to comply with any order issued by the environmental control board within the office of administrative trials and hearings or commissioner of environmental protection or with the conditions of any permit, or such board or commissioner otherwise deems it necessary, the corporation counsel, acting in the name of the city, may maintain an action or proceeding in a court of competent jurisdiction to compel compliance with or restrain by injunction the violation of any order or permit issued by such board or commissioner. f. Civil penalties. Any person who violates or fails to comply with any of the provisions of subdivision b or b-1 of section 1403 of the charter or section 24-504 through 24-523 of this chapter or any order or of any rule issued by the environmental control board within the office of administrative trials and hearings or commissioner of environmental protection pursuant to such provisions or subdivision a of this section in furtherance of such provisions or with the conditions of any permit issued pursuant thereto shall be liable for a civil penalty not exceeding ten thousand dollars for each violation, provided that this subdivision shall not apply to subdivision c of section 24-509 or subdivisions a and b of section 24-521, and provided that the penalty for the removal of a manhole cover in violation of section 24-517 shall be not less than two thousand five hundred dollars. In the case of a continuing violation each day's continuance shall be a separate and distinct offense. The office of administrative trials and hearings, pursuant to section 1049-a of the charter, shall have the power to impose such civil penalties. A proceeding to impose such penalties shall be commenced by the service of a notice of violation returnable to such office. Such office, after a hearing provided in accordance with applicable law and rules, shall have the power to enforce its final decisions and orders imposing such civil penalties as if they were money judgments pursuant to subdivision d of section 1049-a of the charter. A civil penalty imposed by such office may also be collected in an action brought in the name of the city in any court of competent jurisdiction. The environmental control board within the office of administrative trials and hearings, in its discretion, may, within the limits set forth in this subdivision, establish a schedule of civil penalties indicating the minimum and maximum penalty for each separate offense or may use a schedule adopted by the department of environmental protection. g. Criminal penalties. In addition to the civil penalties set forth in subdivision f of this section, any person who knowingly violates or fails to comply with any provision of subdivision b or b-1 of section 1403 of the charter or sections 24-504 through 24-523 of this chapter or any order or rule issued by the environmental control board within the office of administrative trials and hearings or commission of environmental protection pursuant to such provisions or subdivision a of this section in furtherance of such provisions or with the conditions of any permit issued pursuant thereto shall be guilty of a misdemeanor and, upon conviction thereof, shall be punished by a fine of not less than two hundred fifty nor more than ten thousand dollars, or by imprisonment not exceeding thirty days, or both for each offense, provided that this subdivision shall not apply to subdivision c of section 24-509 or subdivisions a and b of section 24-521, and provided that the punishment for the removal of a manhole cover in violation of section 24-517 shall be a fine of not less than five hundred dollars nor more than ten thousand dollars, or imprisonment not exceeding thirty days, or both for each offense.

(3) Points of disposal for storm water disposed of pursuant to this subdivision are: (A) the New York Harbor, or a point on a tidal creek acceptable to the commissioner as an adequate storm water outlet; provided that only building storm sewers and, if necessary, street storm sewers are constructed and that no sewage is discharged at such a point of disposal; and provided that such outlets shall only be used in compliance with applicable provisions of law; (B) a public street storm sewer or public street combined sewer, regardless of its distance from the property, to which the commissioner determines that conveyance of storm water is feasible, as described in subdivision (g) of this section, provided that no sewage shall be discharged into a street storm sewer; or (C) an existing private street storm sewer or private street combined sewer to which the commissioner determines that conveyance of storm water is feasible, as described in subdivision (g) of this section; provided that such street sewer connects with a public street sewer or, if it is a private storm sewer, discharges directly into the New York harbor, or into a point on a tidal creek acceptable to the commissioner as an adequate storm water outlet, in accordance with applicable provisions of law; and provided further that no sewage shall be discharged into a street storm sewer. (d) Required conveyance of storm water for off-site disposal, on or after January first, nineteen hundred ninety-four, when no public sewers into which discharge is feasible are located within five hundred feet of property. The requirements set forth in this subdivision shall apply to the construction of all new buildings for which new building permits have been filed on or after January first, nineteen hundred ninety-four. If the commissioner determines that no public street storm sewer or public street combined sewer is located within five hundred feet, measured along a street, alley or right-of-way, from any point on the boundary of a development or of a lot not contained in a development into which it would be feasible to discharge storm water from such development or such lot, an owner of a lot within such a development or of such a lot not within a development who is constructing or causing to be constructed a building on such lot shall dispose of storm water falling or coming to rest within such lot, together with storm water falling or coming to rest on all streets and other paved areas outside of such lot which are constructed or altered in connection with the construction of such building for the primary purpose of improving vehicular or pedestrian access thereto, by means acceptable to the commissioner and the commissioner of buildings, including but not limited to those set forth in section P110.13 of this reference standard; provided, however, that such persons shall not be required to construct street storm sewers or street combined sewers for distances greater than seven hundred fifty feet. (e) Maximum required capacity for street storm sewers or street combined sewers required by this section. The commissioner may require an owner of a lot or a development who is required by this section to construct street storm sewers or street combined sewers to construct such sewers with a capacity not to exceed twenty-five percent above and beyond the capacity which the commissioner determines is needed for the disposal of storm water falling or coming to rest on such property together with storm water falling or coming to rest on all streets and other paved areas outside of such property which are constructed or altered in connection with the construction of a building or buildings on such property for the primary purpose of improving vehicular or pedestrian access thereto. The department reserves the right to construct catch basins connected to such sewers at the cost and expense of the city, to alleviate flooding or ponding conditions, provided that the commissioner determines that the capacity of such sewers shall not be exceeded. (f) Repair of defects in catch basins and sewers required. Any owner of property who causes any catch basin or any sewer which shall lie outside of such property to be constructed pursuant to subdivision (b), (c) or (d) of this section shall cause all defects in such catch basin or sewer and all faults in its installation to be repaired for a period of two years after it has been installed, immediately after the department orders such person to do so. (g) Feasibility of discharging storm water into a street storm sewer or a street combined sewer. The commissioner shall determine that the discharge of storm water into a street storm sewer or a street combined sewer pursuant to this section is feasible if he or she finds that: (1) the sewer is of adequate capacity to receive all such storm water or would be adequate to receive it if the owner of property installed controlled flow storm water systems, in accordance with the requirements of section P110.6 of reference standard RS-16 of this code, to restrict the maximum anticipated storm water flow to a level set by the commissioner; (2) the sewer is in adequate physical condition to receive such storm water; (3) no physical obstacle which would make conveyance of such storm water to the sewer impracticable exists between the sewer and the boundaries of the development or lot from which such storm water shall be discharged; (4) conveyance of such storm water to the sewer is not impracticable because of the elevation of the sewer in relation to the development or lot from which such storm water shall be discharged; (5) the sewer is located in the same drainage area as all or most of the development or lot from which such storm water shall be discharged; and (6) no other factor reasonably related to the conveyance of such storm water from such development or lot to the sewer would make the discharge of such storm water into the sewer impracticable or undesirable as a proper means of storm water disposal. (h) Time by which construction of the part of the storm water drainage system required by this section shall be completed. The part of the storm water drainage system for property required by this section shall be completed prior to the issuance of a certificate of occupancy by the department of buildings for, and actual occupancy of, the building in connection with which such storm water drainage system is being constructed. (i) Performance bond, license and insurance required. If an owner of property is required to construct or repair defects in catch basins or sewers which shall lie outside of such property, in connection with the construction of a new building pursuant to this section, he or she shall provide the department with: (1) a performance bond or other security satisfactory to the department and approved as to form by the law department of the city for the full cost, as estimated by the department, of performing all such construction and repair work; (2) any license or other written instrument which the commissioner or the law department of the city may reasonably request which gives the department, its agents and contractors and the surety for a performance bond described in paragraph one of this subdivision the legal right to enter private property to perform such construction and repair work, pursuant to the terms of the performance bond or in accordance with the conditions of acceptance of other security described in paragraph one of this subdivision, and the legal right to connect to, to extend or to discharge storm water into any private sewer authorized as a point of disposal pursuant to paragraph three of subdivision (c) of this section, in the event that the owner of property fails to do so as required by this section; and (3) insurance of a kind and in an amount which the commissioner and the law department of the city deem satisfactory to insure the city fully for all risks of loss, damage to property or injury to or death of persons to whomever occurring arising out of or in connection with the performance of such sewer construction and repair work. (j) Contractual obligations of the city not abrogated. The provisions of this section shall not be construed to abrogate or contravene any contractual obligation of the city to construct storm water drainage systems or parts thereof. The requirements of subdivisions (b), (c), (d), (f) and (i) of this section shall be inapplicable to an owner of property insofar as they relate to any construction work required to be performed by the city pursuant to such a contractual obligation. (k) Determination by the board of standards and appeals. Any determination made by the board of standards and appeals with reference to the disposal of storm water, pursuant to the provisions of section 27-160 and section P110.2 of reference standard RS-16 of this code, shall be binding upon the department for the purposes of the enforcement and administration of this section.
