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

2 STORM DEBRIS MANAGEMENT Storm Debris Quantity Estimates Based upon Corps of Engineer Debris Models

3 STORM DEBRIS MANAGEMENT Hurricane 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 and approved 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 Construction & Demolition Wastes Management –An estimated 140, ,000 homes in Southeast Louisiana received flood damage All White Goods (refrigerators, stoves, washer-dryers, etc) All White Goods (refrigerators, stoves, washer-dryers, etc) were removed from each home for recycling All thermostats were removed because they contain All thermostats were removed because they containmercury All smoke detectors were removed because they contain 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 Household Hazardous Waste (pesticides, bleach, solvents, etc.) were removed from each home for disposal Vehicles, boats were hauled to staging areas 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 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 ACM – 1% by weight that can be crushed with hand pressure Regulated by EPA, LDEQ & OSHA Regulated by EPA, LDEQ & OSHA RACM must be disposed in a Type 1 or 2 landfill RACM must be disposed in a Type 1 or 2 landfill Non RACM (Cat 1 & 2) may be disposed in a Construction & Debris landfill Non RACM (Cat 1 & 2) may be disposed in a Construction & Debris landfill

11 Regulated Asbestos- Containing Material (RACM) a.friable asbestos material; a.friable asbestos material; b.Category I nonfriable ACM that has become friable; 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 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. 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 Roofing (Cat 2 non-Regulated - RACM) Asbestos Siding (Cat 2 non-Regulated) Asbestos Siding (Cat 2 non-Regulated) Thermal System Insulation (TSI) Regulated Thermal System Insulation (TSI) Regulated Other Regulated ACM or RACM Other Regulated ACM or RACM Popcorn Ceiling - Regulated Drop down ceilings - Regulated Sheetrock mud – Regulated Window caulking, Vinyl Asbestos Tile 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) 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). 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 Structures completely knocked down by the Hurricanes – not applicable to NESHAPS Partially knocked down structures – applicable Partially knocked down structures – applicable –No inspections, segregation & disposal in a Type 1, 2, or 3 landfill Sound Structures – applicable 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. 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 Removal of non RACM by mechanical means Employs best management practices – wetting, bagging, segregation, and disposal Employs best management practices – wetting, bagging, segregation, and disposal Disposal in a segregated area of a C&D disposal site Disposal in a segregated area of a C&D disposal site More cost effective and saves landfill capacity More cost effective and saves landfill capacity
