§ 13-04 Wetting.
RCNY § 13-04
(a)Provision shall be made at every construction site to control the amount of airborne dust released off site from construction operations, by wetting the construction material as necessary with appropriate spraying agents, provided wetting will not damage utility infrastructure or create any safety hazards. Other means or dust-control apparatus may also be used provided they are acceptable to the Commissioner. Fire hydrants shall not be opened to accomplish this purpose unless a fire hydrant use permit is in effect.
(b)Trucks and other vehicles used to transport particulate matter shall be covered and any particulate matter kept on site shall be sufficiently wetted or stored to prevent particulate matter from becoming airborne.
(c)The wet method of dust control shall include an adequate and continuous supply of water delivered to the construction site under proper pressure and distributed by a hose system and terminating in suitable water sprays or jets at the several points of application, or shall provide the same facilities by means of a self-contained recirculating system. For excavation jobs, a fine mist is deemed to be an adequate supply of water. The application of water shall be done in such a way so as not to create a slipping hazard. Controlled filled operations shall be exempt from this section. When the fill pile is to remain on site and undisturbed overnight or longer, the pile shall be covered with a tarp.
(d)Portable hand water sprinklers or hose sprinklers are acceptable means of wetting for dust control. The water sprays or jets shall be designed to break the water stream into small droplets or otherwise to provide effective wetting.
(e)Suitable drainage means shall be provided for the removal of water and sludge which drains from the operation. When no such drainage is available, the use of access roads and other acceptable methods shall be used.
