RCNY § 2-13
(i)A single boiler stack servicing a single building structure.
(ii)Contiguous construction (i.e., attached "row" houses).
(iii)Separate entrances with separate addresses all serviced by the same boiler room.
(3)This section will be applied to existing facilities to the maximum extent possible consistent with good engineering practices. Alternative and less costly options to altering the stack should be permitted if it can be shown that this will not cause degradation of boiler performance. Degradation of boiler performance would increase air pollutant emissions or inhibit compliance with boiler upgrading criteria.
(4)For new and existing chimneys, emission impacts upon sensitive receptors including, but not limited to, windows, doors that open, people, and building fresh air intakes must be minimized by employing good air pollution control engineering practices. Such practices include, without limitation: (i) Avoiding locations that may be subject to downwash of the exhaust; and (ii) Installing stacks of sufficient height in locations that will prevent and minimize flue gas impacts upon sensitive receptors.
(5)Since this chapter's tables were developed using assumed average meteorological conditions in New York City, situations being disputed may be resolved by the submission of individualized computations of pollutant concentration at the receptor using realistic and applicable factors in dispersion models recommended and approved by the New York State Department of Environmental Conservation and the federal Environmental Protection Agency. The modeling must show that National Ambient Air Quality Standards will not be exceeded at any sensitive receptors, including openable windows and fresh air intakes. The tests, modeling, analysis and costs for these study(s) must be the responsibility of the applicant. (Amended City Record 5/13/2016, eff. 6/12/2016)
