    for the issuing of Construction Noise Permits for construction work within a designated area involving the use of SPME other than percussive piling and/or the carrying out of PCW pursuant to sections 8 & 8A of the Ordinance; and,

    for determining whether or not any such Construction Noise Permit is being complied with.

    In areas, other than a designated area, or when the construction work does not involve the use of SPME nor the carrying out of PCW, the procedures governing the issuing of Construction Noise Permits shall be in accordance with the Technical Memorandum on Noise from Construction Work other than Percussive Piling.
