Inquiry

WCA Bondad Landfill has developed a plan for LEED-NCv2.2, MRc2, Construction Waste Management for a project in Western Colorado. Due to limited options for waste recycling in this rural region of Colorado, WCA Bondad Landfill has developed an alternate approach that we believe is consistent with the intent of MRc2 and with previous CIR rulings. Two waste bins will be placed on the job site. One bin will be placed for general refuse (commonly known as "MSW" or "Municipal Solid Waste"), which is non-recyclable trash (food waste, etc.). The other bin will be reserved for materials to be utilized as alternate daily cover ("ADC"), also known as "beneficial layer" at the landfill. This material will include large plastic, packaging material, non-contaminated soil that cannot be used on-site and any other clean trash or construction waste materials that there are no recycling options for in the area. All ferrous metals will be diverted and recycled. Masonry, concrete, and sheetrock will be reused on site as fill and soil amendment. Federal regulations require waste disposal facilities to cover the working face of a landfill at the end of each operating day with six inches of earthen material, or an approved ADC. As noted in a CIR for MR Credit 2.1 (Inquiry ID 0277-MRc21-041902) landfills typically use soil from the initial excavation of the pit as the daily cover material. However, landfills in southwestern Colorado - and around the country - run out of clean fill from their own excavation stocks. At times, WCA Bondad Landfill mines clean earth, or purchases soil which is routinely trucked from soil quarries at a distance. WCA\'s processing and use of this non-recyclable contractor waste as ADC will prevent the need for WCA to mine, purchase or transport ADC, thus effectively diverting materials from the waste stream by reusing them at the landfill. Our approach will be consistent with a CIR dated 5/17/2002 in which non-recyclable material is processed at the landfill and used as Alternate Daily Cover. The difference here is that the material processed to be used as ADC will not be marketed as a product for sale or for use elsewhere, as was the Barrier product referenced in the previous CIR. The environmental benefits will be the same however. Consistent with the CIR dated 5/17/2002, all quantities will be tracked and actual use at the landfill will be documented. Please confirm that our approach is compliant with NCv2.2, MRc2.

Ruling

The project is inquiring whether the intent of MRc2 is met when project materials are used as alternative daily cover (ADC) at a landfill. Any construction debris processed into a recycled content commodity which has an open market value - e.g. alternative daily cover material, etc. - may be applied to the construction waste calculation.
