From and after October 31, 1994:
A. A person who knowingly releases into the ambient air any extremely hazardous substance listed pursuant to 42 U.S.C. section 11002(a)(2) or any hazardous air pollutant and who knows at the time that he thereby places another person in imminent danger of death or serious bodily injury shall be guilty of a class 2 felony. For any air pollutant for which the administrator, director or control officer has established a standard by regulation or in a permit, a release of such pollutant in accordance with that standard shall not constitute a violation of this subsection. For purposes of determining whether a defendant who is an individual knew that the violation placed another in imminent danger of serious bodily injury both of the following shall apply:
1. The defendant is responsible only for actual awareness or actual belief possessed.
2. Knowledge possessed by another person but not by the defendant may not be attributed to the defendant.
Notwithstanding paragraphs 1 and 2 of this subsection, circumstantial evidence, including evidence that the defendant took affirmative steps to be shielded from relevant information, may be used to prove knowledge.
B. A person who operates a source that is required to have a permit both under this article and under title V of the clean air act and who knowingly operates such source without a permit issued by the control officer and without having filed a complete application for renewal of an existing permit in accordance with title V of the clean air act and this article is guilty of a class 5 felony.
C. A person who operates a source that is subject to an emission standard that is required to be imposed in the source's permit both under this article and under title V of the clean air act, and who knowingly violates such emission standard is guilty of a class 5 felony.
D. A person who is subject to an effective order of abatement issued under this article and who knowingly violates such order is guilty of a class 5 felony.
E. A person who is required by the control officer pursuant to this article to conduct performance tests, and who knowingly alters or modifies any such performance test in order to render the results inaccurate is guilty of a class 5 felony.
F. A person who is required by the control officer to maintain any monitoring device pursuant to this article, and who knowingly alters, modifies or destroys such monitoring device in order to render the device inaccurate is guilty of a class 5 felony.
G. A person who operates a source that is required to have a permit issued pursuant to this article and that is subject to a material permit condition other than an emission standard identified in subsection C of this section, and who knowingly violates such permit condition is guilty of a class 6 felony. For purposes of this subsection a material permit condition means a permit condition determined by the director by rule to be material pursuant to section 49-464, subsection G.
H. A person who is required to obtain a permit before commencing construction of a source both under this article and under title V of the clean air act, and who knowingly commences construction of such source without a permit issued by the control officer is guilty of a class 6 felony.
I. A person who operates a source that is not identified in subsection B of this section and that requires a permit under this article, and who knowingly operates such source without a permit issued by the control officer and without having filed a complete application for renewal of an existing permit in accordance with this article is guilty of a class 6 felony.
J. A person who is required by the control officer pursuant to this article to operate a monitoring device, and who knowingly fails to maintain, operate or repair such monitoring device in order to render the device inaccurate is guilty of a class 6 felony.
K. A person who is required to obtain a permit to commence construction of a source under this article but not under title V of the clean air act, and who acting with criminal negligence commences construction of such source without a permit issued by the director is guilty of a class 1 misdemeanor.
L. A person who acting with criminal negligence does any of the following is guilty of a class 1 misdemeanor:
1. Violates a permit condition not described in subsection C or G of this section.
2. Violates an opacity standard, unless the opacity standard is required by section 111 or title I, part C or D, of the clean air act.
3. Violates a fee or filing requirement established both under this article and under title V of the clean air act.
4. Violates any other provision of this article for which a penalty is not otherwise prescribed.
M. Under this section, a knowing violation that continues for more than one day, but that results from a single act or series of related acts, constitutes the commission of a single offense.
N. In determining the amount of a fine under this section, the court shall consider all of the following:
1. The seriousness of the violation.
2. As an aggravating factor only, the economic benefit, if any, resulting from the violation.
3. Any history of that violation.
4. Any good faith efforts to comply with the applicable requirements.
5. The economic impact of the penalty of the violator.
6. The duration of the violation as established by any credible evidence including evidence other than the applicable test method.
7. Payment by the violator of penalties previously assessed for the same violation.
8. Other aggravating and mitigating factor as the court deems relevant.
O. It shall be an affirmative defense to any prosecution under subsection A of this section that the conduct charged was freely consented to by the person endangered and that the danger and conduct charged were reasonably foreseeable hazards of either of the following:
1. An occupation, business or profession.
2. Medical treatment or medical or scientific experimentation conducted by professionally approved methods provided that the person endangered was made aware of the risk involved in the treatment or experimentation prior to giving consent.
P. It shall be an affirmative defense to any prosecution for violation of an emission standard or opacity standard under subsection C or G or subsection L, paragraph 1, 2 or 4 of this section that both of the following conditions were satisfied:
1. The violation was reported by verbal or facsimile notification to the control officer within twenty-four hours after the source first learned of the violation.
2. The owner or operator of the source provided written notification to the control officer containing all of the following information within seventy-two hours following the verbal or facsimile notification:
(a) Confirmation of the violation for which verbal or facsimile notification was provided.
(b) Identification of the practicable corrective measures that have been undertaken or will be undertaken to control and minimize emissions until compliance with the applicable standard is achieved.
In the case of continuous or recurring violations, the notification requirement shall be satisfied if the source provides the required notification after violations are first detected and includes in such notification an estimate of the time the violations will continue. Violations occurring after the estimated time period shall require additional notification pursuant to the first sentence of this paragraph.
Q. It shall be an affirmative defense to any prosecution under subsection B, H, I or K of this section for operating a source or commencing construction without a permit that, after accurately disclosing in writing all relevant information that is necessary to assess the requirement to obtain a permit and that is requested by a permitting authority, the defendant obtained and relied upon the written advice of a permitting authority that no permit was necessary. Failure of a permitting authority to respond in writing to a request for a determination under this subsection within fourteen days after receiving the information described above shall be deemed to be advice that no permit was necessary for purposes of this subsection.
R. The defendant may establish an affirmative defense provided by this section by a preponderance of the evidence.
S. Under this section, to prove a knowing violation the state must prove actual knowledge of circumstances constituting each element of the offense which, as defined, requires proof of a culpable mental state. Actual knowledge may be proved by either direct or circumstantial evidence, including evidence that the person deliberately avoided acquiring such knowledge. A person's knowledge may not be inferred merely by his or her position within an enterprise.
T. For purposes of this section, the term "emission standard" means a numeric limitation on the volume or concentration of air pollutants in emissions from a source or a specific design, equipment or work practice standard, the purpose of which is to eliminate or reduce the volume or concentration of pollutants emitted by a source. The term emission standard does not include opacity standards. Violations of emission standards shall be determined in the manner prescribed by the applicable regulations issued by the administrator or the director or control officer.
