OAR 340-223-0030
BART Requirements for the Foster-Wheeler Boiler at the Boardman Coal-Fired Power Plant (Federal Acid Rain Program Facility ORISPL Code 6106)
(1)
Emissions limits:(a)
Between July 1, 2011 and December 31, 2020, nitrogen oxide emissions must not exceed 0.23 lb/mmBtu heat input as a 30-day rolling average, provided that:(A)
If the source submitted a complete application for construction and/or operation of pollution control equipment to satisfy the emissions limit in subsection (1)(a) at least eight months prior to the compliance date of July 1, 2011, and the Department has not approved or denied the application by the compliance date, the compliance date is extended until the Department approves or disapproves the application, but may not be extended to a date more than five years from the date that the United States Environmental Protection Agency approves a revision to the State of Oregon Clean Air Act Implementation Plan that incorporates OAR 340-223-0030 (BART Requirements for the Foster-Wheeler Boiler at the Boardman Coal-Fired Power Plant (Federal Acid Rain Program Facility ORISPL Code 6106)); and(B)
If it is demonstrated by December 31, 2011 that the emissions limit in subsection (1)(a) cannot be achieved with combustion controls, the Department by order may grant an extension of compliance to July 1, 2013.(b)
Except as provided in section (3) below:(A)
Between July 1, 2014 and June 30, 2018, sulfur dioxide emissions must not exceed 0.40 lb/mmBtu heat input as a 30-day rolling average; and(B)
Between July 1, 2018 and December 31, 2020, sulfur dioxide emissions must not exceed 0.30 lb/mmBtu heat input as a 30-day rolling average.(c)
Between July 1, 2014 and December 31, 2020, particulate matter emissions must not exceed 0.040 lb/mmBtu heat input as determined by compliance source testing.(d)
During periods of startup and shutdown, the following emissions limits apply instead of the limits in subsections (a) through (c):(A)
Sulfur dioxide emissions must not exceed 1.20 lb/mmBtu, as a 3-hour rolling average;(B)
Nitrogen oxide emissions must not exceed 0.70 lb/mmBtu, as a 3-hour rolling average; and(C)
Particulate matter emissions must be minimized to extent practicable pursuant to approved startup and shutdown procedures in accordance with OAR 340-214-0310 (Excess Emissions and Emergency Provision: Planned Startup and Shutdown).(e)
The Foster-Wheeler boiler at the source must permanently cease burning coal by no later than December 31, 2020. Notwithstanding the definition of netting basis in OAR 340-200-0020 (General Air Quality Definitions), and the process for reducing plant site emission limits in OAR 340-222-0043, the netting basis and PSELs for the boiler are reduced to zero upon the date on which the boiler permanently ceases burning coal, and prior to that date the netting basis and PSELs for the boiler apply only to physical changes or changes in the method of operation of the source for the purpose of complying with emission limits applicable to the boiler.(2)
Studies to evaluate compliance with the sulfur dioxide emissions limits in paragraphs (1)(b)(A)–(B), and the potential side effects of compliance with those limits, if required by section (3), must be completed as follows:(a)
A plan to evaluate the sulfur dioxide emissions limit in paragraph (1)(b)(A) must be submitted for Department approval by July 1, 2011, and the results of the evaluation must be submitted to the Department by July 1, 2013;(b)
A plan to evaluate the sulfur dioxide emissions limit in paragraph (1)(b)(B) must be submitted for Department approval by July 1, 2015, and the results of the evaluation must be submitted to the Department by July 1, 2017; and(c)
Each study pursuant to this section (2) must:(A)
Evaluate whether a dry sorbent injection pollution control system is technically infeasible, will prevent compliance with mercury emissions limits under OAR 340-228-0606 (Utility Mercury Rule, General Provisions: Hg Emission Standards), or cause a significant air quality impact (as that term is defined in 340-200-0020 (General Air Quality Definitions)) for PM10 or PM2.5;(B)
Evaluate a range of commercially available sorbent materials that could be used in a dry sorbent injection pollution control system to reduce sulfur dioxide emissions;(C)
Evaluate the potential for significant air quality impacts for PM10 or PM2.5 as follows:(i)
Perform modeling consistent with the requirements of OAR 340-225-0050 (Requirements for Analysis in PSD Class II and Class III Areas)(1) with screening meteorological data containing conservative meteorological assumptions; or(ii)
If modeling with screening meteorological data pursuant to subparagraph (i) demonstrates that significant air quality impacts for PM10 or PM2.5 will occur, perform modeling with site specific meteorological data obtained from the installation of a meteorological monitoring station, including one year of monitoring data for each study. The meteorological monitoring station must be installed, certified, operated and maintained, and the output of the meteorological monitoring station must be recorded, in accordance with a plan approved by the Department;(D)
Evaluate the use of other sulfur dioxide pollution control systems of equal or lower cost as a dry sorbent injection pollution control system, including but not limited to the use of ultra-low sulfur coal, if the study demonstrates that the use of a dry sorbent injection pollution control system is technically infeasible, will prevent compliance with mercury emissions limits under OAR 340-228-0606 (Utility Mercury Rule, General Provisions: Hg Emission Standards), or will cause a significant air quality impact (as that term is defined in OAR 340-200-0020 (General Air Quality Definitions)) for PM10 or PM2.5; and(E)
If applicable, propose an emissions limit for sulfur dioxide based on a 30-day rolling average that exceeds the limits listed in paragraphs (1)(b)(A)–(B), based upon the reduction of sulfur dioxide emissions to the maximum extent feasible through the use of a dry sorbent injection pollution control system or another sulfur dioxide pollution control system of equal or lower cost, including but not limited to the use of ultra-low sulfur coal, provided that the emissions limit may not exceed 0.55 lb/mmBtu heat input as a 30-day rolling average.(3)
Between July 1, 2014 and December 31, 2020, sulfur dioxide emissions may exceed the limit listed in paragraph (1)(b)(A) or (B), or both, if:(a)
Studies have been submitted pursuant to section (2);(b)
Compliance with the applicable emissions limit or limits would:(A)
Be technically infeasible;(B)
Prevent compliance with mercury emissions limits under OAR 340-228-0606 (Utility Mercury Rule, General Provisions: Hg Emission Standards); or(C)
Cause a significant air quality impact, as that term is defined in OAR 340-200-0020 (General Air Quality Definitions), for PM10 or PM2.5;(c)
Sulfur dioxide emissions are otherwise reduced to the maximum extent feasible as described in subsection (2)(c); and(d)
The source’s Oregon Title V Operating Permit is modified to include a federally enforceable permit limit reflecting the requirements of subsection (2)(c), prior to the compliance date for the sulfur dioxide emissions limit in paragraph (1)(b)(A) or (B) that will be exceeded; provided that if the source’s Oregon Title V Operating Permit has not been modified prior to the applicable compliance date, sulfur dioxide emissions may exceed the emissions limit in paragraph (1)(b)(A) or (B) if the source submitted a complete application to modify its Oregon Title V Operating Permit at least eight months prior to the applicable compliance date and sulfur dioxide emissions do not exceed the emissions limit proposed in its application (which may not exceed 0.55 lb/mmBtu heat input as a 30-day rolling average).(4)
Compliance demonstration. Using the procedures specified in section (5) of this rule:(a)
Compliance with a 30-day rolling average limit must be demonstrated within 180 days of the compliance date specified in section (1) of this rule; and(b)
Compliance with any 30-day rolling average limit for sulfur dioxide that may be established pursuant to subsection (3)(c) must be demonstrated within 180 days of the compliance date for the limit in paragraph (1)(b)(A) or (B) that is superseded by the emissions limit established pursuant to subsection (3)(c).(5)
Compliance Monitoring and Testing.(a)
Compliance with the emissions limits in subsections (1)(a), (b) and (d)(A)–(B), and with any emissions limit for sulfur dioxide that may be established pursuant to subsection (3)(c), must be determined with a continuous emissions monitoring system (CEMS) installed, operated, calibrated, and maintained in accordance with the acid rain monitoring requirements in 40 CFR Part 75 as in effect on December 9, 2010.(A)
The hourly emissions rate in terms of lb/mmBtu heat input must be recorded each operating hour, including periods of startup and shutdown.(B)
The daily average emissions rate must be determined for each boiler operating day using the hourly emissions rates recorded in (A), excluding periods of startup and shutdown.(C)
30-day rolling averages must be determined using all daily average emissions rates recorded in (B) whether or not the days are consecutive.(D)
The daily average emission rate is calculated for any calendar day in which the boiler combusts any fuel. An operating hour means a clock hour during which the boiler combusts any fuel, either for part of the hour or for the entire hour.(b)
Compliance with the particulate matter emissions limit in subsection (1)(c) must be determined by EPA Methods 5 and 19 as in effect on December 9, 2010.(A)
An initial particulate matter source test must be conducted by January 1, 2015.(B)
