7009.0020 PROHIBITED EMISSIONS.

No person shall emit any pollutant in such an amount or in such a manner as to cause or contribute to a violation of any ambient air quality standard beyond such person's property line, provided however, that in the event the general public has access to the person's property or portion thereof, the ambient air quality standards shall apply in those locations. The general public shall not include employees, trespassers, or other categories of people who have been directly authorized by the property owner to enter or remain on the property for a limited period of time and for a specific purpose.

7009.0030 ENFORCEMENT.

The requirement in part 7009.0020 applies without respect to whether emission rules stated in other air pollution control rules of the agency are also being violated. However, in enforcing the ambient air quality standards specified in parts 7009.0010 to 7009.0080, the agency shall not seek payment of a civil or criminal penalty from a person to or with whom a permit or stipulation agreement has been issued or entered into by the agency if and only if:

A.

that permit or stipulation agreement establishes emission limitations or standards of performance for the pollutant or precursor thereof for which there is an ambient air quality standard which has been violated; and

B.

the person to or with whom the permit or stipulation agreement has been issued or entered into by the agency was in compliance with the corresponding emission limitations and standards of performance at the time of the violation of the ambient air quality standard.

7009.1030 EPISODE DECLARATION.

Subpart 1.

Alert.

An air pollution alert shall be declared by the commissioner when the commissioner finds that the concentration of any air pollutant has reached the alert level at any monitoring site and meteorological conditions are such that the air pollutant concentration can be expected to remain at, or exceed, the alert level for 12 or more hours or, in the case of ozone, to recur the following day at the same or higher levels unless control actions are taken.

Subp. 2.

An air pollution warning shall be declared by the commissioner when the commissioner finds that the concentration of any air pollutant has reached the warning level at any monitoring site and meteorological conditions are such that the air pollutant concentration can be expected to remain at, or exceed, the warning level for 12 or more hours or, in the case of ozone, to recur the following day at the same or higher levels unless control actions are taken. An air pollution warning shall also be declared by the commissioner when the commissioner finds that the alert level concentrations for any air pollutant have persisted in the area for 48 hours and are expected to continue for the subsequent 12 hours.

Subp. 3.

Emergency.

An air pollution emergency shall be declared by the commissioner when the concentration of any air pollutant has reached the emergency level at any monitoring site and meteorological conditions are such that the air pollutant concentration can be expected to remain at, or exceed, the emergency level for 12 or more hours or, in the case of ozone, to recur the following day at the same or higher levels unless control actions are taken. An air pollution emergency shall also be declared by the commissioner when the commissioner finds that the warning level concentrations for any air pollutant have persisted in the area for 48 hours and are expected to continue for the subsequent 12 hours.

Subp. 4.

Significant harm episode.

An air pollution significant harm episode shall be declared by the commissioner when the concentration of any air pollutant has reached the significant harm level at any monitoring site and meteorological conditions are such that the air pollutant concentration can be expected to remain at, or exceed, the significant harm level for 12 or more hours or, in the case of ozone, to recur the following day at the same or higher levels unless control actions are taken.

Subp. 5.

Geographical area.

The geographical area subject to episode levels of any air pollutant shall be delineated to the extent feasible and shall be identified in the commissioner's declaration.

Subp. 6.

End of episode.

The commissioner shall terminate the episode by declaration when:

A.

the measured air pollutant concentrations no longer satisfy the criteria specified in part 7009.1020; and

B.

the meteorological conditions indicate that there will not be a recurrence of episode levels of air pollutants within 24 hours of control actions are reduced or eliminated.

7009.1040 CONTROL ACTIONS.

Subpart 1.

Compliance required.

Notwithstanding the provisions of other rules or of any installation permit, operating permit, stipulation agreement, variances, or order of the agency, all persons shall, upon notification by the commissioner or the commissioner's designee, comply with episode control directives issued by the commissioner.

Subp. 2.

Control directive.

Control directives issued to any owner or operator of an emission facility shall be based on the emission reduction plan submitted to the commissioner pursuant to subpart 3; provided, however, that in the event that no emission reduction plan has been approved for such facility, the episode control directives shall be based upon the emission reduction objectives set forth at subpart 4.

Subp. 3.

Episode emission reduction plan.

The owner or operator of each emission facility or stationary source located in an area of the state designated by the commissioner as having exceeded the alert levels in part 7009.1060, table 1, within the last ten years and having allowable emissions of greater than or equal to 250 tons per year of the pollutant causing the episode, shall submit to the commissioner an episode emission reduction plan to be implemented at the facility or stationary source in the event of a declaration by the commissioner of an air pollution episode. The plan shall be submitted to the commissioner within 90 days of the designation of the area or by September 1, 1995, whichever is later. The plan shall be consistent with the emission reduction objectives in subpart 4 and shall designate at least two individuals to be notified in the event of the declaration of an air pollution episode. The plan shall be subject to the approval of the commissioner. If the commissioner finds that the plan is inconsistent with such emission reduction objectives, the plan shall be returned to the owner or operator along with a written statement of the reason(s) for disapproval. The owner or operator shall correct the deficiency within 30 days of notification of disapproval and shall resubmit the plan to the commissioner.

Subp. 4.

Emission reduction objectives.

For the purpose of these parts, emission reduction objectives shall be as indicated in tables 2 through 6 in parts 7009.1070 to 7009.1110. In the event of episode levels of both particulate matter and sulfur dioxide the commissioner shall direct coal fired electric power generating facilities which pollutant is to be reduced at each facility.

Subp. 5.

Right to enter.

During the time that an air pollution episode declaration is in effect and has not been terminated, the owner or operator of any emission facility who has been directed to implement any portion of the facility's emission reduction plan shall allow the agency, or any authorized employee or agent of the agency, when authorized by law and upon the presentation of proper credentials to enter upon the property of the owner or operator for the purpose of obtaining information or examining records or conducting surveys or investigations pertaining to the operation of the emission facilities and the control equipment. The owner or operator shall make available on the premises to such agency employee a copy of the episode emission reduction plan for the emission facility and shall, upon request of the agency employee, demonstrate that the control directives issued to the owner or operator are being implemented.
