  1. Environmental Issues and Concerns Louisiana Dept. of Environmental Quality Debris Management

  2. STORM DEBRIS MANAGEMENT Storm Debris Quantity EstimatesBased upon Corps of Engineer Debris Models

  3. STORM DEBRIS MANAGEMENTHurricane Katrina Generated an estimated 22 million tons (55 million cubic yards) of debris

  4. Hurricane Rita Generated an estimated 2.6 million tons (6 million cubic yards) of debris

  5. Debris management sites were identified by the local parishes, evaluated andapproved by LDEQ Woodwaste Burning Operations Woodwaste Chipping and Grinding Construction and Demolition Staging or Disposal Staging of Boats, Vehicles, White Goods Staging of Household Hazardous Waste

  6. STORM DEBRIS MANAGEMENT • Construction & Demolition Wastes Management • An estimated 140,000-160,000 homes in Southeast Louisiana received flood damage • All White Goods (refrigerators, stoves, washer-dryers, etc) were removed from each home for recycling • All thermostats were removed because they contain mercury • All smoke detectors were removed because they contain small amounts of radioactive materials • Household Hazardous Waste (pesticides, bleach, solvents, etc.) were removed from each home for disposal •  Vehicles, boats were hauled to staging areas

  7. Current debris management sites - Used to process 67% of the Katrina and Rita generated debris Approximately 173 Sites in Katrina Impacted Parishes Approximately 170 Sites in Rita Impacted Parishes

  8. Current Debris Management There are still millions of cubic yards of debris that needs to be cleaned and disposed in South Louisiana from Hurricanes Katrina and Rita

  9. Current Debris Management Asbestos Containing Materials (ACM) have slowed the process of demolishing residential structures and rebuilding

  10. National Emission Standards for Hazardous Air Pollutants (NESHAPS) • Regulated ACM – 1% by weight that can be crushed with hand pressure • Regulated by EPA, LDEQ & OSHA • RACM must be disposed in a Type 1 or 2 landfill • Non RACM (Cat 1 & 2) may be disposed in a Construction & Debris landfill

  11. Regulated Asbestos-Containing Material (RACM) • a. friable asbestos material; • b. Category I nonfriable ACM that has become friable; • c. Category I nonfriable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading; or • d. Category II nonfriable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by this Subchapter.

  12. Types of ACM Found in Homes • Asbestos Roofing (Cat 2 non-Regulated - RACM) • Asbestos Siding (Cat 2 non-Regulated) • Thermal System Insulation (TSI) Regulated • Other Regulated ACM or RACM Popcorn Ceiling - Regulated Drop down ceilings - Regulated Sheetrock mud – Regulated • Window caulking, Vinyl Asbestos Tile (Cat 1 non RACM)

  13. Why Residential Structures are Regulated • Facility—any institutional, commercial, public, industrial, or residential structure, installation, or building (including any structure, installation, or building containing condominiums or individual dwelling units operated as a residential cooperative, but excluding residential buildings having four or fewer dwelling units) • Installation—any building or structure or any group of buildings or structures at a single demolition or renovation site that are under the control of the same owner or operator (or owner or operator under common control).

  14. NESHAP Applicability • Structures completely knocked down by the Hurricanes – not applicable to NESHAPS • Partially knocked down structures – applicable • No inspections, segregation & disposal in a Type 1, 2, or 3 landfill • Sound Structures – applicable • Full inspections, segregation & disposal in a Type 1 2, or 3 landfill

  15. LDEQ Protocol for Removal of RACM • LDEQ believes that removal of ACM from homes can be conducted in an effective manner that is protective of the public. • Removal of non RACM by mechanical means • Employs best management practices – wetting, bagging, segregation, and disposal • Disposal in a segregated area of a C&D disposal site • More cost effective and saves landfill capacity
