OAR 340-214-0330
Excess Emissions and Emergency Provision: All Other Excess Emissions
(1)
For all other excess emissions not addressed in OAR 340-214-310, 340-214-320, or 340-214-360, the following requirements apply:(a)
The owner or operator of a large source, as defined by OAR 340-214-0010 (Definitions), must immediately notify DEQ of the first onset per calendar day of any excess emissions event, unless otherwise specified by a permit condition.(b)
The owner or operator of a small source, as defined by OAR 340-214-0010 (Definitions), need not immediately notify DEQ of excess emissions events unless otherwise required by a permit condition, written notice by DEQ, or if the excess emission is of a nature that could endanger public health.(c)
Additional reporting and recordkeeping requirements are specified in OAR 340-214-0340 (Excess Emissions and Emergency Provision: Reporting Requirements).(2)
During any period of excess emissions, DEQ may require that an owner or operator immediately reduce or cease operation of the equipment or facility until the condition causing the excess emissions has been corrected or brought under control. DEQ will consider the following factors:(a)
The potential risk to the public or environment;(b)
Whether shutdown could result in physical damage to the equipment or facility, or cause injury to employees;(c)
Whether any Air Pollution Alert, Warning, Emergency, or yellow or red woodstove curtailment period exists; and(d)
Whether continued excess emissions were avoidable.(3)
If there is an on-going period of excess emissions, the owner or operator must cease operation of the equipment or facility no later than 48 hours after the beginning of the excess emission period, if the condition causing the emissions is not corrected within that time. The owner or operator does not have to cease operation if DEQ approves procedures to minimize excess emissions until the condition causing the excess emissions is corrected or brought under control. DEQ will consider the following before approving the procedures:(a)
Why the condition causing the excess emissions cannot be corrected or brought under control, including equipment availability and difficulty of repair or installation; and(b)
Information as required in OAR 340-214-0310 (Excess Emissions and Emergency Provision: Planned Startup and Shutdown)(2)(b), (c), and (d) or 340-214-0320 (Excess Emissions and Emergency Provision: Scheduled Maintenance)(1)(b), (c), and (d), as appropriate.(4)
DEQ will approve the procedures if it determines that they are consistent with good pollution control practices, will minimize emissions during such period to the extent practicable, and that no adverse health impact on the public will occur. The owner or operator must record all excess emissions in the excess emissions log as required in OAR 340-214-0340 (Excess Emissions and Emergency Provision: Reporting Requirements)(3). At any time during the period of excess emissions DEQ may require the owner or operator to cease operation of the equipment or facility, in accordance with section (2). Approval of these procedures does not shield the owner or operator from an enforcement action, but DEQ will consider whether the procedures were followed in determining whether an enforcement action is appropriate.
