    501.3.8 (5.3.8) Building Site Waste Management.

    501.3.8.1 (5.3.8.1)Building Site Waste Management Plan.

    A building site waste management plan shall be developed and implemented for excavated soil, rock, and land-clearing debris. Land-clearing debris is limited to stumps and vegetation. Diverted land-clearing debris and removed rock and soil shall not be sent to sites where development activity is prohibited by Section 501.3.1.2 (5.3.1.2) or to greenfields other than those being used for agricultural purposes or being developed as part of a building project.

    Not less than 90% of the land-clearing debris, excluding invasive plant materials, shall be diverted from disposal in landfills and incinerators other than waste-to-energy systems with an energy-recovery efficiency rate higher than 60%. Land-clearing debris calculations shall be based on either weight or volume but not both. Receipts or other documentation related to diversion shall be maintained through the course of construction.

    The plan shall address all of the following:

    1. a.Land-clearing debris, rock, and soil to be diverted from disposal by composting, recycling, or reuse.

    2. b.Waste materials that will be diverted on-site.

    3. c.The locations to which waste materials will be diverted off-site.

    4. d.Soils to be stockpiled for future use at any location.

    5. e.Woody waste to be used as fuel.

    6. f.The destruction and disposal of invasive plant materials.

    7. g.The methods of removal of any contaminated soils.

    8. h.The treatment of vegetation to comply with the rules of government-designated quarantine zones for invasive insect species.
