Order: 

R307·107·1. Application. 

R307-107 applies to all regulated pollutants including 

those for which there are National Ambient Air Quality 

Standards. Except as otherwise provided in R307-107, 

emissions resulting from an unavoidable breakdown 

will not be deemed a violation of these regulations. If 

excess emissions are predictable, they must be 

authorized under the variance procedure in R307-102­

4. Breakdowns that are caused entirely or in part by 

poor maintenance, careless operation, or any other 

preventable upset condition or preventable equipment 

breakdown shall not be considered unavoidable

breakdown. 

R307-107-2. Reporting. 

A breakdown for any period longer than 2 hours must 

be reported to the executive secretary within 3 hours of 

the beginning of the breakdown if reasonable, but in no 

case longer than 18 hours after the beginning of the 

breakdown. During times other than normal office 

hours, breakdowns for any period longer than 2 hours 

shall be initially reported to the Environmental Health 

Emergency Response Coordinator, Telephone (801) 

536-4123. Within 7 calendar days of the beginning of 

any breakdown of longer than 2 hours, a written report 

shall be submitted to the executive secretary which 

shall include the cause and nature of the event, 

estimated quantity of pollutant (total and excess), time 

of emissions and steps taken to control the emissions 

and to prevent recurrence. The submittal of such 

information shall be used by the executive secretary in 

determining whether a violation has occurred and/or 

the need of further enforcement action. 

R307-107-3. Penalties. 

Failure to comply with the reporting procedures of 

R307-107-2 will constitute a violation of these 

regulations. 

R307-107-4. Procedures. 

The owner or operator of an installation suffering an 

unavoidable breakdown shall assure that emission 

limitations and visible emission limitations are 

exceeded for only as short a period of time as 

reasonable. The owner or operator shall take all 

reasonable measures which may include but are not 

limited to the immediate curtailment of production, 

operations, or activities at all installations of the source 

if necessary to limit the total aggregate emissions from 

the source to no greater than the aggregate allowable 

emissions averaged over the periods provided in the 

source's approval orders or R307. In the event that 

production, operations or activities cannot be curtailed 

so as to so limit the total aggregate emissions without 

jeopardizing equipment or safety or measures taken 

would result in even greater excess emissions, the 

owner or operator of the source shall use the most 

rapid, reasonable procedure to reduce emissions. The 

owner or operator of any installation subject to a SIP 

emission limitation pursuant to these rules shall be 

deemed to have complied with the provisions of R307­

107 if the emission limitation has not been exceeded.

R307-107-5. Violation. 

Failure to comply with curtailment actions required by 

R307-107-4 will constitute a violation of R307-107. 

R307·107·6. Emission Standards. 

Other provisions of R307 may require more stringent 

controls than listed herein, in which case those 

requirements must be met.
