Re: Notice of Construction Application and Technical Document Arden Lumber Facility Boiler Replacement Colville, Washington

Dear Karin:

On behalf of Columbia Cedar, Inc., (CCI), enclosed is a Notice of Construction (NOC) application and supporting technical document for permitting of a new boiler to replace a boiler that is currently permitted for the Arden Lumber facility. CCI operates a lumber planer and drying system at the Boise Cascade Wood Products (BCWP) Arden mill located in Colville, Washington. The mill currently operates pursuant to the requirements of Approval Order No. 15AQ-E608 and Air Operating Permit No. 16AQ-E002, issued by your office to BCWP.

In April 2019, the natural gas boiler that provides steam for the drying kilns experienced mechanical problems and had to be removed from service. CCI located and contracted for a temporary natural gas boiler to support continuing drying operations while a new boiler could be located and permitted. On May 2, 2019, representatives of CCI and BCWP met with Jenny Filipy and other representatives from your office to review the concerns and plan the path forward for permitting the necessary modifications to these operations. We greatly appreciate their valuable time and assistance with these permitting requirements.

An NOC application for the operation of the temporary boiler was submitted to you on June 17, 2019, and is currently under review by Andy Kruse of your staff. A copy of a State Environmental Policy Act (SEPA) checklist developed by CCI and BCWP was included with the NOC application for the temporary boiler. The SEPA checklist was written for both the temporary boiler and the new boiler projects.

Please contact me if you have any questions or if there is any other assistance that we may be able to provide to facilitate the review of this application and the issuance of an Approval Order. Thank you.

1.0 INTRODUCTION Landau Associates, Inc. (LAI) has been contracted by Columbia Cedar, Inc. (CCI) to develop an air quality Notice of Construction (NOC) application required by the Washington State Department of Ecology (Ecology) for the replacement of a boiler that recently failed with a new boiler. This document provides the detailed information required for the NOC application for operation of the new boiler at the Boise Cascade Wood Products, LLC, (BCWP) Arden Lumber (Facility). The information presented herein includes specifications for the boiler equipment and detailed operations information, calculated potential emissions that result from operation of the equipment, and a review of the applicable regulations. A review of Best Available Control Technology (BACT) is also included. The NOC application form with detailed facility and contact information is provided in Appendix A.

Landau Associates


2.0 BACKGROUND INFORMATION In April 2019, the natural gas boiler for the Arden operations failed. To maintain operations, CCI has leased a temporary boiler from a supplier in the region. The temporary boiler is intended to partially meet production demands until a new boiler can be located, purchased, approved, and installed. A separate NOC application for the short-term operation of the temporary boiler was submitted to the Ecology on June 17, 2019. This application addresses operations and emissions associated with the new boiler.

The combustion of fuels in boiler operations cause emissions of regulated air pollutants. Potential air pollutants that will be emitted during boiler operations include particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOCs), and oxides of nitrogen (NOx), which are regulated as criteria pollutants. Other combustion-related emissions are regulated as hazardous air pollutants (HAPs) and/or toxic air pollutants (TAPs).

Washington environmental regulations establish air permitting requirements for natural gas-fired boilers with heat input limits of greater than 4 million British thermal units per hour (Btu/hr) under Washington Administrative Code (WAC) 173-400-110. These regulations also require that, prior to construction of a facility that may emit air contaminants, an NOC application be submitted to and reviewed by Ecology. Upon Ecology’s determination that the operations will be in accordance with all applicable air quality requirements, an Approval Order is issued, authorizing construction of the project to commence.

Landau Associates


3.0 FACILITY DESCRIPTION The Facility is a lumber milling operation located in Stevens County at 634 Highway 395 South, Colville, Washington. The legal description for the site is E OF COVILLE RIVER & S OF LITTLE PEND OREILLE RIVER & W OF RR SW4; W OF RR SW4 SE4. Figure 1 presents a map of the vicinity with the Facility location identified.

BCWP owns the Facility, maintains the environmental operating permits for the Facility, and operates the log yard and sawmill. CCI leases and operates the boilers, kilns, and planers. CCI operates under the Boise Cascade environmental permits.

Figure 2 presents a site view of the Facility. Operations include a log yard, lumber manufacturing, lumber storage areas, repair and maintenance facilities, and offices and hogged fuel storage. Raw logs are milled and dried at the Facility before being sent to lumber kilns for drying. Dried lumber is taken to the planer where it is surfaced and trimmed with saws to meet product specifications. Steam for the lumber kilns was previously provided by a Combustion Engineering boiler with a maximum natural gas heat input rating of 25.3 million Btu/hr. Steam is currently supplied by a temporary natural gas-fired boiler installed to maintain operations until this proposed new boiler has been approved for operations.

The Facility operates in accordance with an Air Quality Approval Order (AO) No. 15AQ-E608 (Ecology 2015) issued by Ecology on July 21, 2015 and in accordance with Air Operating Permit (AOP) No. 16AQ-E002 (Ecology 2016) issued by Ecology on May 4, 2016. These permits establish production and emissions limitations for a hogged fuel boiler, the natural gas boiler, the drying kilns, the planer operations, and the truck loading bin.

Landau Associates


4.0 PROJECT DESCRIPTION Recent failure of the natural gas-fired boiler has resulted in the need to find and purchase a replacement boiler to maintain lumber drying operations at the mill. With this application, BCWP and CCI propose the installation and operation of a new boiler to provide for continued operations at the Facility.

4.1 Equipment Description This section presents a detailed description of each of the boilers related to this project. Figure 3 presents a process flow diagram illustrating the boiler system configuration including the new replacement boiler.

4.1.1 Old Boiler The previously operated boiler, or “old boiler,” is a 1954 Combustion Engineering unit rated at 20,000 pounds (lbs) of steam per hour and 500 pounds per square inch (psi). The old boiler was originally permitted and installed at the Facility in 1993. The old boiler utilized flue gas recirculation (FGR) and low-NOx burners to lower NOx emissions. Per Ecology AO No. 15AQ-E608, the maximum heat input for the old boiler was 217 million standard cubic feet per year (MMscf/yr) of natural gas.

4.1.2 Temporary Boiler The temporary boiler is a 1996 Wishaupt RGL11/1-D version ZMO, Serial # 4332401. This boiler is rated at 17.4 million Btu/hr maximum heat input rate with manifold pressure of 7.43 inches of water. The boiler sits on a portable skid and has not been permanently installed at the Facility. An NOC application for the operation of the temporary boiler has been submitted to and is under review by Ecology.

4.1.3 Proposed New Natural Gas Fired Boiler The new boiler is a 600 HP Series 2600D Model 150S manufactured by Williams & David. The boiler will be equipped with an ultra-low NOx burner with a maximum natural gas heat rate input of 25.2 million Btu/hr. Appendix B presents specification documents provided by the vendor regarding the operation and performance of the proposed new boiler.

4.2 Air Contaminants Emitted The combustion of natural gas to fire the proposed new boiler will cause the generation and emissions of air pollutants including PM, CO, VOCs, and NOx, which are regulated as criteria pollutants. Other combustion-related emissions are regulated as HAPs and/or TAPs.

A list of air contaminants that may be emitted during boiler operations is presented in Table 1. Table 1 also identifies whether the pollutant is regulated as a criteria pollutant, HAP, and/or TAP.

Abbreviations and Acronym: CO = carbon monoxide NO2 = nitrogen dioxide Cond = condenseable NOx = nitrogen oxide Filt - filterable SO2 = sulfur dioxide HAPs = hazardous air pollutants TAPs = toxic air pollutants HC = hydrocarbons VOC= volatile organic compound

4.3 Projected Construction Start and Completion Dates The new replacement boiler was ordered by CCI on May 21, 2019. It is expected to be delivered by August 16, 2019 and readied for installation once an Approval Order is issued for that equipment or by mid-September, whichever is later. The temporary boiler will cease operations before the new boiler is operational, or for a maximum of 248 days.

4.4 Operating Schedule and Production Rates The proposed new boiler will be operated 24 hours/day and 7 days/week to produce steam to support the Facility lumber drying operations. The maximum heat rate input is 25.2 million Btu/hr, or approximately 24,700 scf of natural gas per hour.

4.5 Fuel Specifications The burner will be fired with natural gas only. Pipeline quality natural gas is provided to the Facility from the Williams Northwest Pipeline Sumas Compressor Station.

Landau Associates


5.0 APPLICABLE REGULATORY REQUIREMENTS The proposed boiler replacement is subject to Washington and federal regulatory requirements related to control of emissions of criteria pollutants, TAPs, and HAPs. This section provides a summary of the applicable requirements.

5.1 Washington Administrative Codes The Facility and the proposal for installation and operation of the new boiler are regulated under WACs pursuant to the Washington Clean Air Act (WCAA) and Revised Codes of Washington (RCW) 70.94. This section summarizes the WAC requirements relevant to the proposed modification.

5.1.1 Chapter 173-400 WAC - General Regulations for Air Pollution Sources Under WAC 173-400, the Facility is regulated as a stationary source and the proposed boiler is regulated as an emissions unit. Specific provisions of WAC 173-400 that are relevant to the proposed modification include:

• WAC 173-400-040 General standards for maximum emissions.

• WAC 173-400-050 Emission standards for combustion and incineration units.

• WAC 173-400-075 Emission standards for sources emitting hazardous air pollutants.

• WAC 173-400-110 New source review (NSR) for sources and portable sources.

• WAC 173-400-113 New sources in attainment or unclassifiable areas.

5.1.2 WAC 173-401 – Operating Permit Regulation The Facility is a “major source” of air pollutants in accordance with WAC 173-401 and is, therefore, subject to the operating permit requirements of WAC 173-401. The Facility currently operates under Air Operating Permit No. 16AQ-E002, issued by Ecology on May 4, 2016. New or modified chapter 401 sources, which commence operation after US Environmental Protection Agency (EPA) approval of the state operating program, shall require filing a complete application to obtain the chapter 401 permit or permit revision within 12 months after commencing operation.

5.1.3 WAC 173-460 – Controls for New Sources of Toxic Air Pollutants WAC 173-460-040 establishes review requirements for modified TAP sources. If the increase in emissions from a modification is less than the applicable de minimis emission threshold for that TAP listed in WAC 173-460-150, the modification is exempt from NSR for that TAP. WAC 173-460-150 also establishes small quantity emission rate (SQER) thresholds for TAPs emissions that trigger the requirement to conduct dispersion modeling.

Landau Associates


5.2 New Source Performance Standards (NSPS) The proposed new natural gas boiler is subject to 40 Code of Federal Regulations (CFR) 60 Subpart Dc, Standards of Performance for Industrial-Commercial-Institutional Steam Generating Units, because it is a steam generating unit with a design capacity between 10 and 100 million Btu/hr heat input, that will commence construction after June 9, 1989. However, no emission standards are established for natural gas-fired units. Consistent with the requirements for the old boiler, the Facility will be required to record the amount of fuel combusted in each calendar month [§60.48c(g)(1)], maintain fuel records for 2 years [§60.48c(i)], and submit a notification of construction within 30 days and notification of startup within 15 days [§60.48c(a)].

5.3 National Emission Standards for Hazardous Air Pollutants (NESHAP)

With the issuance of AO 15AQ-E608, Ecology approved voluntary emissions limits (VEL) of 22 tons/year of combined HAPs and 9 tons/year of any individual HAP. The facility is, therefore, not a major source for HAPs emissions. Subpart JJJJJJ, National Emission Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers Area Sources, applies to boilers constructed after June 4, 2010 at area sources of HAPs. However, natural gas-fired boilers are exempt from Subpart JJJJJJ.

Landau Associates


6.0 EMISSIONS EVALUATION This section describes the methodology, emission factors, and estimated emission rates for each of the emitted air contaminants. Emission rates for the proposed new boiler are compared to emissions rates for the old boiler and to the regulatory thresholds and standards for each pollutant.

6.1 Methodology for Estimating Emissions Methods, factors, and operating parameters that have been used to estimate hourly and annual emissions rates for the air contaminants emitted by the new boiler and the old boiler are presented here.

6.1.1 Emission Factors Emission factors used to estimate emissions were taken from four references:

1. EPA Inventory of Emission Factors, AP-42, Tables 1.4 (EPA 1998) for small boilers (boilers with a rating less than 100 million Btu/yr) provides emission factors used to calculate criteria pollutant emissions, except as noted in 3 below.

2. The Ventura County Air Pollution Control District, AB 2588, Combustion Emission Factors (2001) provides emission factors for the calculation of HAPs and TAPs emissions.

3. For the new boiler, information from the manufacturer provides maximum concentrations in parts per million (ppm) of NOx and CO to calculate emissions factors. Power Flame Incorporated presented an emissions guarantee for NOx and CO in ppm by volume (ppmv); provided in Appendix B.

4. For the old boiler, the emission factor used to calculate the NOx emission rate was taken from the 2017 source test conducted by CleanAir (2017).

5. For the old boiler, information from the manufacturer was used for total PM emissions factors. Emissions of PM10 and PM2.5 are calculated based on the total PM emission factor.

Table 2 presents the specific emission factor used for calculating emissions and the reference for each factor.

lb = pound nat gas = natural gas scf – standard cubic foot TAPs = toxic air pollutants

6.2 Calculation of Estimated Pollutant Emissions Potential hourly emissions of each criteria air pollutant and TAP have been calculated using the following formula:

E = Ef * HI * (1MMscf/1020 million Btu) Where,

E = Contaminant emissions (lb/hr) Ef = Emission factor (lb/MMscf of natural gas) HI = Maximum heat input rate (million Btu/hr).

For CO and NOx emissions from the new boiler, emissions were calculated based on the vendor-reported maximum concentrations using methods outlined in EPA’s Preferred and Alternative Methods for Estimating Air Emissions from Boilers (EPA 2001).

E = (C x MW x Q x 60) / (V x 106)

Where,

E = Hourly emissions in lb/hr of pollutant

C = pollutant concentration in parts per million volumetric, dry basis (ppmvd)

MW = molecular weight of the pollutant in lb/lb-mole

Q = stack gas volumetic flow rate in dscfm

V = volume occupied by 1 mole of ideal gas as standard conditions (385 cubic feet [ft3]/lb-mole @ 68 degrees Fahrenheit [°F] and 1 atm).

Landau Associates


The guidance also provides an equation for the calculation of Q when exhaust gas flow rates are unavailable:

Q = Fd x (20.9/(20.9 - %O2) x (HI/60)

Where,

Fd= Ratio of the gas volume of fuel components per unit of heat. For natural gas, this value is provide by EPA Method 19 as 8710 scf/million Btu.

%O2 = measured oxygen concentration dry basis. HI = Heat input rate in million Btu/hr.

Annual emissions have been calculated by multiplying the hourly emissions by the total annual hours of operation.

6.3 Calculated Emissions Table 4 presents a summary of the estimated potential emissions for all pollutants during operation of the proposed new boiler. The results of the calculated potential hourly and annual emissions of criteria pollutants and TAPs for the old boiler and the new boiler are presented in Appendix C. Table C-1 presents the potential emissions for the old boiler and Table C-2 presents potential emissions for the proposed new boiler. The Excel worksheet developed for these emissions calculations has been submitted to Ecology electronically.

7.0 COMPLIANCE WITH APPLICABLE REQUIREMENTS This section presents a discussion of the estimated emissions in relation to the applicable requirements.

7.1 Washington Administrative Code Requirements The project and its estimated emissions in relation to the applicable WAC requirements are discussed here.

7.1.1 WAC 173-400-050 Emission Standards for Combustion Units. This provision limits the emissions of PM to 0.23 grams per dry cubic meter at standard conditions (0.1 grain/dscf). As presented in Appendix C, Table C-3, PM emissions during operation of the new boiler will be less than the PM emissions for the old boiler. With lower PM emissions, it is expected that the new boiler will continue to meet the limit established by this regulation.

7.1.2 WAC 173-400-075 Emission Standards for Sources Emitting Hazardous Air Pollutants.

See section 5.3 for discussions of HAPs compliance.

7.1.3 WAC 173-400-110 New Source Review The proposal to install and operate the new boiler is a modification to an existing stationary source and a modification to a source of TAPs. NSR is required for natural gas-fired combustion units with >4 million Btu/hr. The new boiler has a rated heat input of 25.2 million Btu/hr, so it is not categorically exempt.

As presented in Table 5 above, operation of the proposed new boiler will result in emissions of CO, NOx, lead, total suspended particulates (TSP), and SO2 at rates that are lower than the NSR thresholds for those pollutants. The new boiler will emit PM10 and PM2.5 in quantities that will exceed the annual NSR thresholds. However, the new boiler will emit less of these pollutants that did the old boiler.

7.1.4 WAC 173-400-113 New Sources in Attainment or Unclassifiable Areas As required under WAC 173-400-113, this project will comply with the following regulatory requirements:

1. Compliance with the NSPS is addressed in Section 5.2. Compliance with NESHAPs is addressed in Section 5.3.

2. A BACT review and recommendation for this project are presented in Section 8.

3. Compliance with ambient air quality standards for criteria pollutants discussed in Section 9.

7.2 WAC 173-401 – Operating Permit Regulation An application for revision of the AOP for the Facility will be required to be submitted to Ecology within 12 months after commencement of operation of the new boiler.

Landau Associates


7.3 WAC 173-460 – Controls for Sources of Toxic Air Pollutants Table 6 presents the calculated increase in emissions of TAPs that will occur with the replacement of the old boiler with the new boiler, and compares the calculated emissions with the de minimis threshold and the SQER for each TAP.

These results indicate that, with the combustion of natural gas, operation of the new boiler will emit acrolein, benzene, and formaldehyde in quantities that exceed de minimis thresholds established at WAC 173-460-150. These substances, therefore, require NSR review for this project. None of the TAPs will be emitted in quantities that exceed the SQERs, so dispersion modeling for TAPs is not required. Toxics BACT (T-BACT) for these pollutants is addressed in Section 8.

Landau Associates


8.0 BEST AVAILABLE CONTROL TECHNOLOGY EVALUATION The proposed boiler is equipped with an ultra-low NOx burner with a manufacturer’s guarantee of 9 ppm NOx and <30 ppm CO. This technology has been accepted by Ecology as BACT for natural gas boilers. Additionally, the burner will be operated with accepted good combustion practices and only pipeline quality natural gas will be used.

Landau Associates


9.0 AMBIENT AIR IMPACTS ANALYSES The Facility is located in an area that is in attainment or unclassifiable for all criteria pollutants. Based on the expected reduction in all pollutants with operation of the proposed replacement boiler, it is not expected that this project will cause an exceedance of the National Ambient Air Quality Standards (NAAQS). It is recommended that air dispersion modeling is not necessary for this project.
