        <text>“Installation”, for the purpose of Regulation .06 of this chapter, means an installation as defined in COMAR 26.11.01.01 that can operate independently and that causes VOC emissions to the atmosphere. If equipment at a premises does not operate independently but operates as part of a process line, the process line is considered to be the installation.</text>
      </paragraph>
      <paragraph num="(2)">
        <text>“Process line” means a combination of equipment that operates as a unit to perform a specific function, which either generates VOC or to which VOC is added, and which discharges VOC to the atmosphere through one or more discharge points.</text>
