Read the first 7 Emissions Control & Environmental Compliance flashcards as text

  1. Which OSHA standard primarily governs permissible exposure limits (PELs) for welding fumes in submerged arc welding operations?

    Answer: 29 CFR 1910.1000

    29 CFR 1910.1000 establishes OSHA's table Z-1 permissible exposure limits for airborne contaminants including welding fumes.

  2. In SAW operations, manganese fume exposure is a critical concern. What is the OSHA PEL for manganese fume (ceiling value)?

    Answer: 1 mg/m³

    OSHA sets a ceiling value of 1 mg/m³ for manganese fume to prevent neurological damage from overexposure.

  3. What does the term 'action level' mean in the context of SAW environmental compliance monitoring?

    Answer: One-half of the permissible exposure limit triggering enhanced monitoring

    The action level is typically half the PEL and triggers requirements for increased air monitoring and medical surveillance.

  4. Which EPA program requires facilities that release certain toxic chemicals above threshold quantities to report annually?

    Answer: Toxic Release Inventory (TRI) under EPCRA Section 313

    EPCRA Section 313 requires facilities meeting size and industry criteria to report toxic chemical releases to the EPA's Toxic Release Inventory.

  5. During SAW, flux decomposition can produce sulfur dioxide (SO₂). Which EPA standard regulates SO₂ as a criteria air pollutant?

    Answer: National Ambient Air Quality Standards (NAAQS)

    NAAQS established under the Clean Air Act sets ambient concentration limits for SO₂ as one of six criteria air pollutants.

  6. A SAW facility generates spent flux that tests above EPA hazardous waste thresholds. Under RCRA, this waste must be managed as:

    Answer: Hazardous waste requiring cradle-to-grave tracking

    RCRA Subtitle C requires cradle-to-grave management of hazardous waste, including proper manifesting, storage limits, and disposal at permitted facilities.

  7. What is the primary purpose of a Hazardous Materials Business Plan (HMBP) required in some states for SAW facilities?

    Answer: To notify local emergency responders of chemical inventories and emergency procedures

    HMBPs inform local emergency response agencies about hazardous materials on-site so they can plan for potential releases or incidents.
