Prior to the issuance of any permit for the use of explosives for blasting operations, a permit survey meeting shall be arranged by the owner or the owner's blasting contractor and conducted at the job site at which blasting operations are to occur, for the purpose of reviewing the measures that the blasting contractor will be required to undertake to safeguard affected buildings, structures and infrastructure. Such permit survey meeting shall be attended by representatives of the department, general contractor and blasting contractor. The owner or the owner's blasting contractor shall invite the participation of owners of affected buildings, structures and infrastructure as determined by the department to be appropriate, and shall in addition notify the Department of Buildings of the meeting. The commissioner may also require notification of and coordination with other federal, state and city officials and agencies, including the Department of Environmental Protection, Office of Emergency Management, Metropolitan Transportation Authority, United States Coast Guard and United States Army Corps of Engineers, as appropriate.
Owners of electrical, natural gas, water and other utility infrastructure shall provide information to the department and the blasting contractor, including the location, depth, size, construction, condition and age of such infrastructure, including location of isolation valves, and any other information that the department may require to determine the measures that the blasting contractor will be required to undertake to safeguard such infrastructure during blasting operations. Such information shall be readily available for the duration of blasting operations.
For blasting operations near or adjacent to a natural gas utility infrastructure, the utility company may require access to the job site so that a leak survey may be conducted prior and subsequent to blasting operations. The blasting contractor shall provide the utility company with access to the job site for such purpose.
For demolition blasting, the blasting contractor shall coordinate with and provide access to the utility company to disconnect all power lines within 100 feet (30 480 mm) of the structure to be demolished, and sever physically from the main street lines, and cap as close to the main as possible, all services extending into the structure. Blasting shall not be conducted unless existing utility service street lines are cut and capped.
The blasting contractor shall conduct blasting operations in a manner that minimizes the impact of such blasting operation on public safety. Good faith measures shall be made to schedule blasting at those times when students in affected schools are not arriving, departing or outdoors, and when services are not being held at houses of worship, and to otherwise coordinate the timing of blasting operations to minimize the impact on affected uses and occupancies. Appropriate procedures for coordination and notification shall be established at the permit survey meeting.
Within 5 calendar days of issuance of a permit for the use of explosives for demolition or excavation work, the owner or the owner's blasting contractor shall provide written notice to each council member and community board whose respective district includes the job site or property within 100 feet (30 480 mm) thereof, and the local fire company. Such notice shall contain the effective and expiration dates of the permit. Proof of the delivery or mailing of such notice shall be filed with the department.
Not less than 2 calendar days nor more than 5 calendar days prior to the commencement of blasting operations, the owner or the owner's blasting contractor shall provide written notice of same to each council member and community board whose respective districts include the job site or property within 100 feet (30 480 mm) thereof, and the local fire company. Such notice shall contain the date or dates on which blasting operations are anticipated to take place and telephone numbers for the blasting contractor and the department to which complaints and inquiries about the blasting operations may be made. The owner or the owner's blasting contractor shall in addition forward a copy of the written notice to the owners of all buildings within 100 feet (30 480 mm) of the job site. Owners of such buildings shall post such notice at a conspicuous location within each such building in a manner prescribed by the department to ensure adequate visibility. If blasting operations continue for a period of more than 1 month, additional notice shall be given to owners of such buildings and posted by such owners on a monthly basis for any month in which blasting operations are to be conducted.
The blasting contractor shall provide advance notification of blasting operations to the fire company in whose administrative district the job site is located. Except where overnight storage of explosives is approved and except as may be approved for underground job sites, after the final blast has been fired for the day, the blasting contractor shall arrange with such fire company for an inspection of the job site to confirm removal of explosives as required by this chapter.
