**Determination** After staff investigation reports and other documents in the applicant’s file in the Bureau of Air Quality, pursuant to 38 M.R.S.A, § 344 , § 582, § 590 and § 603 , the Department finds the following facts: **I.

- § 5
- C as an emission limitation based on the degree of reduction achievable through the application of the best system of continuous emission reduction for each visibility
- impairing air pollutant that is emitted b y an existing stationary facility
. The emission limitation must be established, on a case -by
- case basis, taking into consideration the technology available, the costs of compliance, the energy and non - air quality

environmental impacts of compliance, any p ollution control equipment in use or in existence at the source, the remaining useful life of the source, and the degree of improvement in visibility that may reasonably

b e anticipated to result from the use of such technology
. A facility i s determined to have BART eligible emission units if the following criteria outlined in the Regional Haze Rule found in 40 CFR, Part 51 are met: 1. The facility

falls into one the 26 source specific categories identified in the Clean Air Act (CAA) of 1977,**Lincoln Paper and Tissue Co., Inc. Departmental**

h a s emission units that entered operation in the 15 ye ars prior to the adoption of the CAA, and 3. The facility has the potential to emit more than 250 tons/year of a single visibility impairing pollutant from units that fall under criteria #2. Per 38 MRS A § 6 03
- A, sub
- § 8; for those BART eligible units determined by the Department to require additional sulfur air pollution controls to improve visibility, the controls must: 1. Be installed and operational no later than January 1, 2013; and 2. Either: a. Require the use o f oil having 1% or less of sulfur by weight; or, b. Be equivalent to a 50% reduction in sulfur dioxide emissions from a BART eligible unit based on a BART eligible unit source emission baseline determined by the Department under 40 CFR, Section 51.308 (d)(3 )(iii)(2006) and 40 CFR , Section 51, Appendix Y (2006); or, c. Require an SO 2 emiss ions limit of 250 tons per ye ar from the BART eligible unit. B.

Boiler #2 Recovery B oiler #2 was manufactured by B abcock and Wilcox in 1972. The unit is licensed to limit heat input capacity to 1.9 million pounds (MMlbs) of dry black liquor solids (BLS) per day or 500 MMBtu/hr of #6 fuel oil. The Re covery Boiler is used to recover chemicals and produce steam. Emissions ex it through two identical 175 foot stacks. The recovery b oiler is a straight fire unit burning black**Lincoln Paper and Tissue Co., Inc. Departmental**

-ups, shutdowns and to stabilize operation of the boiler. The Recovery

B oiler is exhausted to a wet bottom electrostatic precipitator (ESP) to control particulate emissions. This unit also serves to re - introduce salt cake into the black liquor which further concentrates the solids content. BART Determination 1. PM LPT shall control PM and PM 10 emissions from the recovery b oiler by u sing an ESP to achieve the BACT emission level of 0.044 grains per dry s tandard cubic foot (0.04 4 gr/dscf) corrected to 8% oxygen. 2. SO 2 SO 2 emissions from the recovery b oiler shall be controlled to 141 ppmv (dry basis) @ 8% O 2 on a 24
-hour block average basis when firing onl y black liquor or when firing a combination of black liquor and oil. The reco very boiler fires #6 fuel oil. O il fired in the recovery boiler alone shall not ex ceed 0.7% sulfur by

w eight or 2.0% sulfur by w eight when firing a combination of black liquor and oil. The recovery b oiler is fired with fuel oil for startup purposes (in order to initiate Black Liquor Solids (BLS) firing) in addition to shutdowns and other events which require the addition of oil firing. 3. NO x Recovery Boiler #2 shall not exceed a NOx limit of 233 ppmv corrected to 8% O 2 on a dry

basis. Compliance with the N Ox ppmv emission limit shall be on a 24
-hr block average basis excluding periods of start-up, shutdown and malfunction, demonstrated by means of a CEMS on the stack.
