Classification and reporting;  confidentiality of records
A. The director,  by rule,  shall classify air contaminant sources according to levels and types of emissions and other characteristics which relate to air pollution,  and shall require reporting for any such class or classes. Reports may be required as to physical outlets,  processes and fuels used,  the nature and duration of emissions and such other information as is relevant to air pollution and deemed necessary by the director.
B. The owner,  lessee or operator of a source under the jurisdiction of the department shall provide,  install,  maintain,  and operate such air contaminant monitoring devices as are reasonable,  necessary,  and required to determine compliance in a manner acceptable to the director,  and shall supply monitoring information as directed in writing by the director. Such devices shall be available for inspection by the director,  or his deputies,  during all reasonable times.
C. The department shall make available to the public any records,  reports or information obtained from any person pursuant to this chapter,  including records,  reports or information obtained or prepared by the director or a department employee,  except that the information or any particular part of the information shall be considered confidential on either of the following:
1. Notice from the person accompanying the information or a particular part of the information that the information,  if made public,  would divulge the person's trade secrets as defined in section 49-201 or other information that is likely to cause substantial harm to the person's competitive position.
2. A determination by the attorney general that disclosure of the information or a particular part of the information would be detrimental to an ongoing criminal investigation or to an ongoing or contemplated civil enforcement action filed under this title in superior court.
D. If the director on his own or following a request for disclosure disagrees with the confidentiality notice,  he may request the attorney general to seek a court order authorizing disclosure. If a court order is sought,  the person shall be served with a copy of the court filing and has twenty business days from the date of service to request a hearing on whether a court order should be issued. The hearing shall be conducted in camera,  and any order resulting from the hearing is appealable as provided by law. The director may not disclose the confidential information until a court order authorizing disclosure has been obtained and becomes final. The court may award costs of litigation including reasonable attorney and expert witness fees to the prevailing party.
E. Notwithstanding subsection C,  the department shall make available to the public the following information obtained from any person pursuant to this chapter:
1. The name and address of any permit applicant or permittee.
2. The chemical constituents,  concentrations and amounts of any emission of any air contaminant.
3. The existence or level of a concentration of an air pollutant in the environment.
F. Notwithstanding subsection C,  the director may disclose,  with an accompanying confidentiality notice,  any records,  reports or information obtained by the director or department employees to:
1. Other state employees concerned with administering this chapter or if the records,  reports or information is relevant to any administrative or judicial proceeding under this chapter.
2. Employees of the United States environmental protection agency if the information is necessary or required to administer and implement or comply with federal statutes or regulations.
