§ 13-06 Construction Activities Requiring Additional Forms of Dust Control.

   (a)   Where the demolition or renovation of any building or other structure is being performed by hand, debris, bricks, and other material shall be removed by means of chutes, by means of buckets or hoists, or through openings in the floors of the building or other structure in compliance with these Rules and the Administrative Code of the city of New York.

   (b)   Where windows and other exterior wall openings in buildings or other structures being renovated are more than 25 feet in height above the ground or grade level and are within 20 feet of any floor opening used for removal of debris from floors above, such windows and other openings shall be solidly boarded up during renovation operations to prevent the emission of dust into the atmosphere so long as applicable OSHA standards are followed.

   (c)   During sandblasting or other similar operations, installation and use of hoods, fans and dust collectors to enclose and vent the handling of dusty materials or the use of water sprays or other measures and control apparatuses acceptable to the Commissioner to suppress the dust emission or adequate containment methods shall be employed.

   (d)   Open-bodied trucks transporting dust producing construction materials likely to become airborne shall be covered at all times when in motion.

   (e)   Removal of earth or other material from paved roads, driveways and parking lots on which earth or other material has been deposited by trucking, earth moving equipment or erosion is required daily. There shall be no re-suspension of roadway dust during the removal process.

   (f)   Dry street sweepers, including broom sweeping, may be used if designed to prevent the re-suspension of street/sidewalk particulate matter.

   (g)   The use of blower devices for the removal of deposited mud or dirt is prohibited.

   (h)   Vehicles entering or exiting construction areas shall travel at slow speeds to minimize dust emissions.

   (i)   Disturbed areas shall be stabilized for the duration of the construction activity or until construction work resumes on the inactive disturbed area. All disturbed areas of a construction site, including storage piles of fill dirt and other bulk materials, which are not being actively utilized for construction purposes for a period of seven calendar days or more, shall be stabilized using one or more of the following soil stabilization methods:

      (1)   Water, as a dust suppressant;

      (2)   Chemical dust stabilizer or suppressant;

      (3)   Planting of trees or vegetative ground cover. Where soil moisture or natural crushing is sufficient to limit visible dust emissions, no action is required.

§ 13-07 Demolition.

   (a)   A DEP demolition registration shall be filed with the Department 10 days prior to the commencement of demolition. Such registration shall include the following information: name of owner or demolition contractor, address of owner or demolition contractor, description of the building, structure, facility or installation, scheduled starting and completion dates of demolition, method of demolition to be employed, and procedure to be employed to meet the requirements of these Rules.

   (b)   Adequate wetting shall be employed before and during the demolition of any section or wall of the structure.

   (c)   Debris shall be transported through dust-tight chutes or in buckets and shall not be dropped or thrown from any floor. Any debris in chutes or buckets shall be sufficiently wetted to preclude dust dispersion at the point of discharge.

   (d)   Dust and debris from the demolition operations shall be removed daily from the adjacent streets, sidewalks and alleys.

   (e)   Any contractor or person who intends to demolish a building, structure, facility or installation to which the provisions of this section apply is exempt from the requirements of this section if such building, structure, facility or installation has been declared by a state or local governmental authority to be structurally unsound and in danger of imminent collapse.

§ 13-08 Sandblasting.

   (a)   No dry sandblasting shall be permitted except where wet sandblasting cannot be done due to unique circumstances.

   (b)   Whenever sandblasting is done, contaminant methods such as blast-cleaning machines and cabinets shall be used.

   (c)   Whenever sandblasting is done, curtains shall be used as temporary dust-containment structures.

   (d)   A minimum of three days notice shall be given by the contractor to owners, tenants and occupants of all structures within one hundred fifty feet of the site on which sandblasting is to be done.

§ 13-09 Construction Devices.

All persons constructing or operating a large article, machine, device, equipment, such as a rock crusher, or other contrivance or facility capable of causing or permitting emission of dust into the atmosphere at a construction site shall keep on site a document detailing such equipment. Information provided on this document shall include the ownership, location, design, make and model, operation, i.e. how does it operate, as well as any other pertinent information requested by the Department. In addition, the measures utilized to reduce dust emissions resulting from the use of these items as set forth in 15 RCNY §§ 13-01 et seq. shall be clearly outlined. This document shall be attached as an addendum sheet to the Noise Mitigation Plan prepared pursuant to § 24-220 of the Noise Code.

§ 13-10 Open Areas.

Owners shall take sufficient measures including wetting and covering and open area to prevent dust emissions from becoming airborne after demolition is completed.
