Results of Sample AnalysesTPH and RCRA metal concentrations well below Vermont ANR Guidelines
for
Petroleum Contaminated Soil and Debris
Hazardous Waste Management Regulations
*Beneficial Re-Use Possible!
![Page 8: Risk Assessment of Disposal Options for Street Debris and Detention Basin Sediments Presented by Matthew Looft Kendall Clare McPeters Danielle Roy Sarah.](https://reader035.fdocuments.in/reader035/viewer/2022070407/56649e2e5503460f94b1ea4a/html5/thumbnails/8.jpg)
Possible Risks if Above ANR Guidelines
• TPH: Total Petroleum Hydrocarbons– Minimal exposure is unavoidable – Acute exposure can cause adverse
reactions in the blood, skin, eyes, legs (paralysis), immune system
– Can linger in soils, film on surface waters, or settle into bottom sediments
![Page 9: Risk Assessment of Disposal Options for Street Debris and Detention Basin Sediments Presented by Matthew Looft Kendall Clare McPeters Danielle Roy Sarah.](https://reader035.fdocuments.in/reader035/viewer/2022070407/56649e2e5503460f94b1ea4a/html5/thumbnails/9.jpg)
Possible Risks Continued…
• RCRA 8 Metals: arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver– Bioaccumulation in plant and animal tissue– Threats to microorganisms in soil ecosystems– Severe allergic reactions– Carcinogenicity– Damaging effects to nervous system and/or
brain of fetuses– DNA damage

Alternative Reuses if Above ANR Guidelines
• Compost– Biologically decomposes organics– Thermal desorption of some volatile organics– Simple process (windrows, turning, wetting)– Valuable topsoil or mulch as end product
• Biological Degradation– Inoculating with soil bacteria, mycelial fungi to
enhance decomposition of pollutants and residues
![Page 12: Risk Assessment of Disposal Options for Street Debris and Detention Basin Sediments Presented by Matthew Looft Kendall Clare McPeters Danielle Roy Sarah.](https://reader035.fdocuments.in/reader035/viewer/2022070407/56649e2e5503460f94b1ea4a/html5/thumbnails/12.jpg)
Suggested Alternatives for Winooski
• “No action” – Continued disposal in landfills
• Daily cover at landfills• Compost additive• Road sand• Containment/absorption material • Roadway fill or backfill• Sub-fill for potholes• Replacement for raw material in concrete
or asphalt• Land reclamation
![Page 13: Risk Assessment of Disposal Options for Street Debris and Detention Basin Sediments Presented by Matthew Looft Kendall Clare McPeters Danielle Roy Sarah.](https://reader035.fdocuments.in/reader035/viewer/2022070407/56649e2e5503460f94b1ea4a/html5/thumbnails/13.jpg)
Case Studies
• Bloomington, MN: 100% reduction of landfilling sweepings by reusing as road sand
• Bangor, ME: reuse as clay composite for rec. trails
• Worcester, MA: development of guidelines for finding reuse alternatives (Chelsea Center)
• Colorado Springs, CO: 100% reduction of landfilled CB sediments by facility for dewatering, screening, composting

Reuse Initiatives
Possibility for an in depth study on beneficial reuse of street sweepings and catch basin sediments to happen at UVM to benefit the Burlington, Winooski, Williston communities?

Community Collaboration and Beyond…
SAND Model
• Sediment Accumulation Nexus District– Regional Collection Community Sediments
• Analysis• Shred/Sort• Wash• Screen• Storage
– Trade for credits– Sell to business or public
![Page 18: Risk Assessment of Disposal Options for Street Debris and Detention Basin Sediments Presented by Matthew Looft Kendall Clare McPeters Danielle Roy Sarah.](https://reader035.fdocuments.in/reader035/viewer/2022070407/56649e2e5503460f94b1ea4a/html5/thumbnails/18.jpg)
Beneficial Reuse• Reapplication for transportation use• Mixed with clay for recreational paths at
Gilbrook Park • Landfill daily/weekly cover for Chittenden
Solid Waste District• Compost additive at the Intervale• Roadway fill or backfill at construction
sites • Fill in crash attenuation barriers along
Interstate 89• Containment/absorption medium for
hazardous material spill response

On Site Remediation
• Composting– Biological decomposition of organics– Thermal desorption of volatile organics
• Biological Degradation– Nutrient cycling– Waste and residue decomposition– Detoxification of environmental pollutants
• Immobilization– Aggregates in concrete or asphalt

Recommendations
Beneficial Reuse will-Be more effective than current practices
-Pay for itself over time-Reduce ‘new sand’ by 90-100%
*Winooski should initiate a local beneficial reuse program to serve as an example for a county wide SAND program
