ENVIRONMENTAL ASPECTS OF

RENOVATION/DEMOLITION/REDELOPMENT

Asbestos

Beneficial Reuse of Demolition Materials

and Industrial Byproducts

Brownfields Redevelopment

Concrete Recycling


  • Introduction

  • A focus exists

  • Don’t fail to plan

  • Manage Risk

  • Approach same as conventional construction


RiskManagement: Project Phases

Maximum

Ability to Control Risk

$$ to Make Changes

Minimum

Design

Planning

Construction

Procurement

Programming

Commissioning

Time



  • Managing Environmental Conditions

    • Minimize release to environment

    • Maintain safe work place and surroundings

    • Ensure proper handling and disposal

    • Avoid contamination through spreading

    • Focus on what will be disturbed



  • A is for ASBESTOS

    • Naturally occurring mined mineral

    • Common building material and product ingredient for heat resistance, binding, acoustical insulation properties

    • Airborne hazard – asbestosis, mesothelioma, lung cancer

    • Regulatory issue – early 1970’s

      • Clean Air Act (CAA) – most friable types banned

      • Toxic Substance Control Act (TSCA) – 1989

      • TSCA ban vacated 1991 – Still in use today


  • Asbestos Contaminated Materials (ACM)

    • Commonly known

      • Thermal system insulation, transite, floor tile and mastic, roofing

      • Melting equipment, heating systems, sound proofing

    • Did you know…

      • paints – plaster/drywall – glazing

      • wire insulation – electrical box-

      • lab counter tops – vermiculite – debris

    • ACBM >1% asbestos (USEPA, WDNR)

    • Asbestos Contaminated Waste

    • Friable, Category I Nonfriable, Category II Nonfriable


  • Asbestos – Why?

    • Regulatory Requirements - Federal

      • Asbestos Hazard Emergency Response Act (AHERA)

      • Department of Health and Family Services (DHFS)

    • Regulatory Requirements - Local

      • Milwaukee Department of Neighborhood Services

    • Other: Transportation, Disposal


  • Asbestos – Why? (cont.)

    • Control Costs

      • handling/abatement

      • disposal

      • fines-WDNR citation NR 447.19

        * Failure to notify

        * Failure to inspect

        * Improper landfill disposal

    • Control Risk

      • owner’s liability

      • occupant’s liability


  • Asbestos – Gathering Information

    • NESHAP & NR447 Require “Thorough Inspection”

      • Industry standards based on AHERA

      • By certified inspector

      • Sampling of homogeneous materials

      • Can assume

    • Pre-Renovation/Demolition Inspection Report

      • Homogeneous material types

      • Sampling location/ floor plans

      • Classification

      • Conditions

      • Quantification

      • Analytical testing results


  • Asbestos – Applying the Information

    • Project Planning

      • when and what to abate

      • material handling

      • budget costing

    • Project Design/Contracting

      • type, quantity, location

      • schedule/sequence

      • by quantity/ type

      • unit costs to control discovery

      • contractor qualifications, experience and reputation


  • Asbestos Abatement

      • 0.06% Pb by weight (liquid)

      • 0.7 mg of Pb per sq. cm. (dry)

    • Lead inspection/sampling

      • X-Ray Fluorescence (XRF) – immediate mg/sq. cm

      • bulk sample – analytical testing % by wt.

    • Concentrate by mechanical means – highly regulated

    • Left in place – worker awareness

COMPETENT PERSON

OSHA – 29 CFR 1926.32

“ During demolition, a potential exists for encountering asbestos and other hazardous materials, and for asbestos and other hazardous materials previously hidden to become exposed. Maintain a minimum of one individual on site during demolition to be designated as a “Competent Person”. This individual shall be familiar with applicable asbestos and hazardous materials related regulations, have the experience to recognize potential work crew and environmental exposures, institute proper personal protective equipment and personnel monitoring as necessary, and have the authority to stop work. All discoveries of suspect asbestos or other hazardous materials shall be reported immediately to the Owner so that the appropriate measures can take place.”
