    Study Notes

    Domain 7 - Environmental Management

    • Percentage: 7.38%

    Hazardous Materials

    • Definition: Any solid, liquid, or gas that can harm people, other living organisms, property, or the environment.
    • Characteristics: Can be radioactive, flammable, explosive, toxic, corrosive, a biohazard, an oxidizer, an asphyxiant, or an allergen.
    • Hazardous Waste Definition: Solid waste with characteristics that pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, or disposed of.
    • Solid Waste: Discarded material disposed of, burned, incinerated, or recycled, and can be solid, liquid, semi-solid, or gaseous.
    • Density: Mass per unit volume (d = m/v)
    • Specific Gravity: Ratio of a material's density to the density of water (SGx = dx /dwater).
      • SG < 1: Lighter than water (floats)
      • SG > 1: Heavier than water (sinks)
    • Solubility: Property of a solute dissolving in a solvent to form a homogenous solution; usually measured in ppm
    • Vapor Density: Weight of a unit volume of gas/vapor compared to an equal volume of air.
      • VD < 1: Lighter than air (rises)
      • VD > 1: Heavier than air (concentrates in low places)

    Regulations

    • Resource Conservation and Recovery Act (RCRA): Regulates hazardous waste from ‘cradle to grave.’
    • Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA): Also known as Superfund, funds and processes cleanup of hazardous waste sites.
    • Superfund Amendment and Reauthorization Act (SARA): Increased fund size, focuses on human health regarding hazardous sites, and encouraged participation
    • Emergency Planning and Community Right-to-Know Act (EPCRA): Protects public from chemical emergencies
    • Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA): No one can sell, distribute, or use a pesticide without EPA registration.
    • Asbestos Hazard Emergency Response Act (1986): Sets guidelines for asbestos inspections and removal.

    Physical Hazards

    • Engulfment: Workers surrounded by substances like soil, grain, or flour, or submerged in liquids.
    • Overpressurization: Increase in ambient temperature, often leading to fires/explosions from increased pressure.
    • Fires and Explosions: Chemical reactions, ignition of explosives/flammable substances, etc.
    • Corrosion: Disintegration of materials due to chemical reactions.
    • Thermal Decomposition: Incomplete combustion by-products (e.g., carbon monoxide).
    • Water Reactivity: Water-sensitive chemicals reacting intensely with moisture.

    Hazardous Waste Operations

    • Planning and Organization: Critical first step with organizational structure, comprehensive work plans, and site safety/health plans.
    • Training: Must cover relevant procedures, nature of risks, emergency handling, and personal responsibility.
    • Medical Program: Pre-employment, periodic/termination screenings, emergency/non-emergency treatment, record keeping, and program review.
    • Site Characterization: Initial hazards and protection methods identified off/on-site.
    • Air Monitoring: Provides constant information on contaminants, proper PPE, and potential exposure assessments.
    • Personal Protective Equipment (PPE): Shields/isolates individuals from environmental hazards.
    • Site Control: Minimizes contamination and protects public from site hazards.
    • Decontamination: Removal/neutralization of contaminants on workers/equipment.

    EPA Categories of Hazardous Waste Generators

    • Large Quantity Generators (LQG): >1000kg (2200lbs) per calendar month.
    • Small Quantity Generators (SQG): >100kg (220lbs) to ≤1000kg(2200lbs) per calendar month.
    • Conditionally Exempt Small Quantity Generators (CESQG): ≤100kg (220lbs) per calendar month.

    1- Solid Waste and Hazardous Waste

    • Waste definitions include garbage, refuse, wastewater treatment plant sludge, and discarded materials from industrial, commercial, and community activities.
    • Hazardous waste characteristics include flammability, corrosiveness, and reactivity.
    • Land Disposal Restrictions (LDRs) prevent unauthorized disposal of contaminated wastes

    2- Universal Waste

    • Batteries, agricultural pesticides, and thermostats are examples of universal wastes.

    3- Used Oil Management Standards

    • Used oil is any oil contaminated from use.
    • Different criteria for used oil, such as origin, contaminants, and use of oil.
    • Agricultural producers who generate 25 gallons or less per month may be exempt from these regulations.

    4- Underground Storage Tanks (USTs)

    • USTs are tanks and connected piping holding at least 10% of their volume underground.
    • USTs holding less than 1100 gallons of motor fuel for noncommercial purposes are excluded from regulations.
    • Some specific types of USTs, such as tanks storing heating oil, are excluded.

    Toxic Substances Control Act (TSCA)

    • TSCA regulates production, importation, use, and disposal of specific chemicals.
    • Substances meeting specific criteria are excluded; this includes existing (TSCA Inventory chemicals) and newer chemicals.
    • Toxicity characteristic leaching procedure (TCLP) determines if a waste is hazardous by testing for certain metals and chemicals within the material.

    Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)

    • FIFRA provides federal regulation of pesticides
    • Pesticides are reviewed every 15 years.
    • It details different types of pesticide reviews.
    • FIFRA has registration criteria for pesticide composition, labeling, intended function, and environmental impact.
    • Product chemistry details technical characteristics of pesticides, their environmental fate, residue chemistry, plus effects on other organisms.

    Clean Air Act (CAA)

    • CAA regulates emissions from stationary and mobile sources.

    • National Ambient Air Quality Standards (NAAQS) are designed to protect public health and welfare.

    • EPA defines 'major sources' for hazardous air pollutants, based on emissions potential. Sources emitting 10 tons per year or more of a hazardous air pollutant are considered major sources.

    • Area sources are those that do not fit the definition of a major source.

    • Specific risks under CAA include acid rain, urban pollution, and toxic air emissions.
