"CERCLA" means the comprehensive environmental response, compensation, and liability act of 1980, as amended (P.L. 96-510; 94 Stat. 2767; 42 United States Code sections 9601 through 9657), commonly known as "superfund". 5. "Clean closure" means implementation of all actions specified in a permit, if any, as closure requirements, as well as elimination, to the greatest degree practicable, of any reasonable probability of further discharge from the facility and of exceeding aquifer water quality standards at the applicable point of compliance. Clean closure also means postclosure monitoring and maintenance are unnecessary to meet the requirements of this chapter. 6. "Clean water act" means the federal water pollution control act amendments of 1972 (P.L. 92-500; 86 Stat. 816; 33 United States Code sections 1251 through 1376), as amended. 7.

"Inert material" means broken concrete, asphaltic pavement, manufactured asbestos-containing products, brick, rock, gravel, sand and soil. Inert material also includes material that when subjected to a water leach test that is designed to approximate natural infiltrating waters will not leach substances in concentrations that exceed numeric aquifer water quality standards established pursuant to section 49-223, including overburden and wall rock that is not acid generating, taking into consideration acid neutralization potential, and that has not and will not be subject to mine leaching operations. 21. "Major modification" means a physical change in an existing facility or a change in its method of operation that results in a significant increase or adverse alteration in the characteristics or volume of the pollutants discharged, or the addition of a process or major piece of production equipment, building or structure that is physically separated from the existing operation and that causes a discharge, provided that: (a) A modification to a groundwater protection permit facility as defined in section 49-241.01, subsection C that would qualify for an area-wide permit pursuant to section 49-243, subsection P consisting of an activity or structure listed in section 49-241, subsection B shall not constitute a major modification solely because of that listing. (b) For a groundwater protection permit facility as defined in section 49-241.01, subsection C, a physical expansion that is accomplished by lateral accretion or upward expansion within the pollutant management area of the existing facility or group of facilities shall not constitute a major modification if the accretion or expansion is accomplished through sound engineering practice in a manner compatible with existing facility design, taking into account safety, stability and risk of environmental release. For a facility described in section 49-241.01, subsection C, paragraph 1, expansion of a facility shall conform with the terms and conditions of the applicable permit.
