(g) The Commissioner may approve an application for a groundwater discharge permit upon demonstration by the applicant, satisfactory to the Commissioner, that: (1) substantial property damage will result unless such groundwater is removed; (2) there is no feasible alternative method of disposal; (3) allowing the discharge will not overload the hydraulic capacity of the sewer, and (4) such discharge will not cause an unacceptable dilution of the influent to the water pollution control plant receiving the groundwater discharge. (h) (1) Permits for the discharge of groundwater into storm sewers shall require, at a minimum, compliance with the following conditions: (i) the discharger shall develop and implement, pursuant to aschedule set by the Commissioner, an alternative method of disposal, unless the applicant demonstrates to the satisfaction of the Commissioner that no such alternative method of disposal exists or can be developed or imple- mented; (ii) the discharger shall indemnify and hold the City of New York barmless for any damage or liability incurred by the City of New York either directly or indirectly, in the event that the discharge results in overloading the capacity of such storm sewer, or otherwise causes flood- ing, and shall also post and maintain such cash or surety bond as may be required and will be satisfactory to the Commissioner and shall supply §19-02 TITLE 15—DEPT.

(b) No stormwater shall be allowed to enter a house drainage system within any area served by a separate sanitary sewerage system. Within any such area, no down spout or leader, gutter or other pipe, drain or channel which may at any time carry stormwater, subsurface drainage derived from hydraulic pressure or from well points, cooling water, or sea water shall be connected to any sanitary sewer. No down spout or leader shall be used as a soil, waste or vent pipe. Every joint in the connection of a house drain to a sanitary sewer shall be made watertight so that no leakage into or from any such drain shall occur.
