SESSION: GREEN WASTE AND STANDARDS Landfill Reuse ASTM Standard Marty Rowland. PhD P.E., Third Leg Consultants There is no comprehensive guide for municipalities, regulators, or landowners for restoring waste disposal sites for beneficial reuse or guide future or active sites to productive post-closure reuse. Many legacy disposal sites cannot develop without clear direction, although many small, 50+ year old municipal trash sites contain waste that has degraded and poses only de minimis risks to human health and the environment. At other waste sites, beneficial reuse is hindered by non-standard directives of hundreds to thousands of U.S. regulators, when common approaches are clearly possible. Internationally, second and third world nations struggle to adopt safe and effective waste management practices, where reuse is not yet a consideration. Potentially valuable land stays unused or misused, municipalities lose opportunities to gain revenue, and landowners face uncertain financial risk in attempting rational reuse options. The solution is the development of an international landfill/waste site reuse guide by the consensus-driven, ASTM task group WK42846, an assemblage of environmental professionals with regulatory, consulting, and waste site management expertise. The task group anticipates having the guide published by mid The leaders of the group present the status of the guide’s development. Amanda Ludlow, Principal Scientist, Roux Associates Marty has served in many capacities as a professional environmental engineer throughout his 38 year career, including NYC Dept of Parks & Recreation contaminated soil expert, Lockheed Martin chlorinated solvent remediation specialist, hazardous waste landfill site manager, environmental consultant, and State of Michigan regulatory official. He played a leading role in the publication of the ASTM Standard E Integrating Sustainable Objectives into Cleanups, and is task lead on ASTM work group WK42846 Beneficial Reuse of Landfills. Marty is a professional civil and environmental engineer, certified hazardous material manager, permaculture design professional, and certified Passive House designer. Amanda Ludlow, Principal Scientist at Roux Associates, Inc., has over 16 years of experience in design and implementation of natural systems for the sustainable remediation of contaminated soils and sediments, industrial and municipal wastewaters, groundwater, surface water, and stormwater. Ms. Ludlow directs the firm’s sustainable remediation practice termed Engineered Natural Systems (ENS®). Ms. Ludlow's expertise extends from constructed treatment wetlands, phytotechnologies, alternative landfill closure, and natural media filtration through the development and design of green infrastructure practices. Ms. Ludlow holds a BS in Bio Engineering, MA in Marine Biology, and a MS in Civil and Environmental Engineering. Ms. Ludlow also specializes in the assessment and restoration of sensitive habitats from freshwater wetlands and tidal wetlands to riparian ecosystems—incorporating bioengineering and living shorelines—to grassland and woodland habitats.

Content Why reuse waste sites? Why ASTM? WK42846 – Landfill Reuse Task Group What the standard would avoid Anticipated use Public/commercial reuse Controls, safety, value recovery Process Next steps Questions?
Why Reuse Waste Sites “They ain’t making any more of the stuff (land)” – Will Rogers Even the worst ones have some value Large demand – brownfields programs What limits their reuse? no comprehensive, professional guide on repurposing sites with chemical and waste exposure challenges today, it is all case-by-case
Why ASTM? History of providing value to target disciplines / industries - E1527Environmental Phase I - E1903Environmental Phase II - E2081Risk-based corrective action -E2876Sustainable Cleanups -E2893Greener Cleanups Consensus based International acceptance
WK42846 Landfill Reuse Task Group Kicked off in April 2013, group has 23 members 2 local officials 3 state officials 3 federal officials 6 waste industry reps 9consultants First complete draft by August 2014 Published standard by October 2015
What the TG Avoids / Minimizes Private transaction costs Necessary, but “wasted” labor Regulatory burden – seeks private/public sector joint interests Oversight duplication – one day, future reuse at design stage
Anticipated Uses Municipal Solid Waste Landfills - pre-RCRA (orphan, latchkey) - operated pre-RCRA, closed post-RCRA - operating - in design Construction and Demolition landfills - closed - operating Historic fill sites Airborne deposition sites Monofill landfills - coal ash - foundry sand Buffer zones
Public / Commerical Reuse Development in lieu of cap Commercial / Industrial use on account of landfill age Incorporate monitoring infrastructure into beneficial reuse Protection of non-RCRA cap Uses that preserve the integrity of RCRA cap Passive uses Active uses Strategic placement of waste and infrastructure Any use, including green energy PV and wind Stability period required
Controls, Safety, Material Recovery Control / Safety - Erosion - Infiltration - Secured monitoring infrastructure - Leachate - Landfill gas - Soil / waste stability - Trespass Value Capture - Material recovery
Process 5 Forms Appendix – guide on documenting what is known what isn’t Form 1 – low risk, expedited approval Form 2 – elevated risk, soft conditions only Form 3 – disturbing cover / cap Form 4 – agricultural operations Form 5 – complex and controversial sites, hard conditions
Potential Uses / Case Studies Newburgh, NY – pre-RCRA operation, latchkey landfill Park in NYC – filled pre-RCRA, closed post-RCRA Ballfield, legacy lead smelter – environmental justice concern Large RCRA Landfill in design – opportunity for lessons learned, design with eye on future reuse
Next Steps Take comments today – first complete draft by August Rework that draft at next ASTM Committee Week in October
