  <paragraph num="A.">
    <text>General. The owner or operator of a containment building shall use controls and practices to ensure containment of hazardous waste within the unit.</text>
  </paragraph>
  <paragraph num="B.">
    <text>Measures to Ensure Containment. To ensure containment of hazardous waste within a containment building, the owner or operator of the containment building shall, at a minimum:</text>
    <paragraph num="(1)">
      <text>Maintain the primary barrier to be free of significant cracks, gaps, corrosion, or other deterioration that could cause hazardous waste to be released from the primary barrier;</text>
    </paragraph>
    <paragraph num="(2)">
      <text>Maintain the level of the hazardous waste being managed in the containment building within the containment walls of the unit so that the height of any containment wall is not exceeded;</text>
    </paragraph>
    <paragraph num="(3)">
      <text>Take measures to prevent the tracking of hazardous waste out of the containment building by personnel or by equipment used in handling the waste;</text>
    </paragraph>
    <paragraph num="(4)">
      <text>In preventing hazardous waste from being tracked out of the containment building:</text>

      </paragraph>
    </paragraph>
    <paragraph num="(5)">
      <text>Take measures to control fugitive dust emissions so that no opening of the containment building, such as doors, windows, vents, cracks, etc., exhibits any visible emissions;</text>
    </paragraph>
    <paragraph num="(6)">
      <text>Use sound air pollution control practices in operating and maintaining all particulate collection devices associated with control of fugitive dust emissions, such as fabric filters or electrostatic precipitators;</text>
    </paragraph>
    <paragraph num="(7)">
      <text>Maintain the state of no visible emissions required by §B(5) of this regulation effectively at all times during routine operating and maintenance conditions, including when vehicles and personnel are entering and exiting the unit; and</text>
    </paragraph>
    <paragraph num="(8)">
      <text>Assure that incompatible hazardous wastes or treatment reagents are not placed in the unit or its secondary containment system if the wastes or reagents could cause the unit or secondary containment system to leak, corrode, or otherwise fail.</text>
    </paragraph>
    <aftertext>Agency Note: See 40 CFR Part 60, Appendix A, Method 22—“Visual Determination of Fugitive Emissions from Material Sources and Smoke Emissions from Flares” for a method for determining whether there are visible emissions from a source.</aftertext>
