NYC's Commercial Recycling Law sets the following requirements for Waste Transfer Stations:

• Recycle, reuse, or sell for reuse all designated recyclables received that have been source separated or commingled as required.
• Maintain the separation of separated paper materials before their transfer to another location.
• Separate by type commingled glass, metal, and plastic materials, unless can demonstrate to DSNY that such materials will be separated for recycling, reuse, or sale for reuse at another location.
• Separate metal components of bulk waste from other designated and non-designated materials, unless can demonstrate to DSNY that this material will be separated for recycling, reuse, or sale for reuse at another location.
• Separate designated construction waste from non-designated components of construction waste before transferring to another location.
• See penalties.

In addition, waste transfer stations must follow NY State transfer station storage requirements.
