Unit 12 - Principles and Practices

Asbestos Found in Real Estate Environments

  • Detailed Definition and Composition: Asbestos is a naturally occurring mineral composed of fibers. It was historically valued for its specific physical properties, notably its fireproofing and insulating qualities.

  • Health Hazards and Inhalation Risks: Asbestos becomes a significant health hazard when its fibers break down and become "friable." In this state, the fibers separate into microscopic particles that can be inhaled into the lungs.

  • Regulatory Status: The use of asbestos in insulation has been banned since the year 19781978.

  • Remediation and Encapsulation: One primary method to manage existing asbestos is encapsulation, which involves sealing off the material to prevent the fibers from becoming airborne.

Lead and Lead-Based Paint Hazards

  • Common Environmental Locations: Lead can be identified in various components of a property, including pipes, pipe solder, paints, air, and soil.

  • Housing Prevalence: Lead-based paint is commonly found in many housing units constructed prior to the year 19781978.

  • Physiological Effects: Lead is known to accumulate within the human body. High levels of lead can cause substantial damage to the brain, the nervous system, the kidneys, and the blood.

  • The Lead-Based Paint Hazard Reduction Act of 19921992 (LBPHRA): This federal act mandates that known lead-based paint hazards must be disclosed to potential buyers or lessees of a property.

  • Mandatory Disclosure Documentation: Real estate professionals are required by law to provide both buyers and lessees with a specific informational pamphlet titled Protect Your Family from Lead in Your Home. This document was collaboratively created by the EPA, HUD, and the Consumer Product Safety Commission.

  • Contractor and Remodeler Regulations:

    • Contractors and individuals performing remodeling work that disturbs painted surfaces in homes, schools, or child care facilities built before 19781978 must undergo specific training.

    • These professionals must be certified in the EPA’s lead-based work practices.

    • Before starting any work, the pamphlet titled Renovate Right must be provided to the property owner.

Radon Gas and Formaldehyde Contamination

  • Radon Gas Characteristics:

    • Radon is a radioactive gas that is entirely odorless and tasteless.

    • It is produced through the natural decay of radioactive substances located in the ground and is present across the United States.

    • Health Implications: Exposure to radon gas is a known cause of lung cancer.

    • Federal Testing Standards: There is currently no federal requirement for radon testing in buildings.

  • Formaldehyde Hazards:

    • Legal Classification: Formaldehyde is classified as a hazardous air pollutant under the Clean Air Act Amendments of 19901990.

    • Common Applications: It is utilized in various building and household products. A notable historical example is Urea-formaldehyde foam insulation (UFFI).

    • Associated Health Problems: Exposure may lead to respiratory issues, irritation of the eyes and skin, and is considered a possible carcinogen (cancer-causing agent).

    • HUD Regulations: Since the year 19851985, the Department of Housing and Urban Development (HUD) has regulated the use of formaldehyde in wood products.

    • Professional Responsibilities: Real estate professionals are advised to check specific state disclosure requirements regarding formaldehyde, and appraisers are expected to note its presence during property evaluations.

Gaseous and Chemical Pollutants: Carbon Monoxide, PCBs, and CFCs

  • Carbon Monoxide (CO):

    • Physical Nature: A colorless and odorless gas produced as a by-product of burning fuel.

    • Danger to Life: Inhaling CO can lead to carbon monoxide poisoning, which is fatal unless the gas is properly vented to the exterior.

    • Safety Measures: CO is identifiable via detectors, which may be mandatory under specific state laws.

  • Polychlorinated Biphenyls (PCBs):

    • Historically found in electrical equipment.

    • PCBs are suspected of causing various health problems.

    • The manufacture and commercial distribution of PCBs has been prohibited since the year 19791979.

  • Chlorofluorocarbons (CFCs):

    • Commonly used in refrigerators, aerosol sprays, paints, solvents, and various foam applications.

    • The manufacture of CFCs has mostly ceased worldwide since the year 19961996.

Biological Hazards, Groundwater, and Wetlands

  • Mold and Moisture Management:

    • The EPA provides specific guidelines for the remediation and cleanup of mold and moisture issues in schools and commercial buildings.

    • If mold is visible or if water problems (leaks) are suspected, real estate professionals should recommend a professional mold inspection.

  • Groundwater Protection:

    • Groundwater is located beneath the earth’s surface and is the source that forms the water table.

    • The Safe Drinking Water Act (SDWA) of 19741974: This act regulates the quality of the public drinking water supply.

    • Transfer of Property Protocol: Whenever a property is transferred, any water source that is not a municipal supply (such as a private well) and any septic system should be tested.

  • Wetlands Preservation: The EPA is responsible for protecting and improving wetland quality under the authority of the Clean Water Act.

Underground Storage Tanks and Waste Disposal

  • Underground Storage Tanks (USTs):

    • USTs often contain petroleum products, industrial chemicals, or other hazardous substances.

    • They are regulated by both federal law (via the EPA) and various state laws.

    • Potential purchasers should conduct a careful inspection of any property where USTs are suspected to exist.

  • Waste Disposal Sites:

    • Ownership and Locations: Disposal sites may be owned by municipalities, operated by commercial enterprises, or located on farms and rural properties.

    • Landfill Design: Modern landfill sites (whether excavated or placed in former mines) are designed with liners to prevent seepage into the ground. They are capped with soil for aesthetic purposes and utilize vents to safely release gases produced by decomposing waste.

Environmental Legislation and Liability: CERCLA and Brownfields

  • Brownfields Legislation: This legislation is designed to encourage the redevelopment of abandoned properties. It functions by shielding "innocent developers" from liability for toxic wastes that were present on the site prior to the purchase.

  • The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA):

    • Administration: Enforced and administered by the EPA.

    • Funding: CERCLA established the "Superfund" to finance the cleanup of uncontrolled hazardous waste sites.

    • Targeted Parties: The act identifies Potential Responsible Parties (PRPs).

    • Definitions of Liability:

      • Strict Liability: The landowner is responsible for cleanup costs and has no legal defense against this responsibility.

      • Joint and Several Liability: Each individual landowner among several involved parties is responsible for the entire cost of the cleanup.

      • Retroactive Liability: Both the current owner and previous owners can be held responsible for the cleanup of hazardous materials.

    • Exemptions: CERCLA also defines the specific criteria under which innocent landowner immunity applies.

Professional Environmental Due Diligence in Real Estate

  • Discovery of Hazards: Real estate professionals should actively attempt to discover environmental hazards by questioning property owners.

  • Environmental Site Assessment (ESA): Professionals should recommend an ESA when appropriate.

    • Phase 11 ESA: Consists of a physical examination of the property and a thorough investigation into its historical usage.

    • Phase 22 ESA: Involves the actual sampling of soil and other materials. This phase is triggered if the Phase 11 assessment indicates a potential problem.

  • Environmental Impact Statement (EIS): This is a required document for projects that receive federal funding and may also be mandated by specific state or local governments.

  • Unit Reference: This curriculum is captured within Unit 2121: Environmental Issues and the Real Estate Transaction.
