San Francisco, CA 94105
Dear Mr. Haber:
With this letter, the District is providing the EPA with Official Notice of a proposed Title V permit reopening for a minor permit modification in accordance with Title 5 permitting requirements of the federal Clean Air Act of 1990. We believe this project meets the requirements for a minor modification as per section 70.7(e)(2). Attached are copies of the permit review and proposed permit unit addition to the Title V permit.
In accordance with District Regulation 5, EPA will have 45 days from the date of receipt of this letter to provide written comments to the District regarding this proposed permit issuance. Earlier comments are suggested to help speed up this minor permit revision.
Sincerely,
Robert Clark
District Engineer

SIMPSON REDWOOD COMPANY, KORBEL
Simpson Redwood has a new sawmill multi-saw trimmer which trims different size lumber to a variety of lengths. In the process of sawing this lumber, sawdust is created which needs to be removed from the sawing process. The pneumatic system designed for the removal of the sawdust uses a 54” diameter cyclone and a 40 horsepower blower for the conveyance of the sawdust to the storage bin located at the Planing Mill.
From past experience, the emissions from this type of process when processing green(non-dried) lumber produces sawdust which collects easily due to the inherent weight of the moist sawdust. The District has made calculations based upon expected emissions:
Flow, cfm x grain loading, gr/cf x 60 min/hr
---------------------------------------------------------- = pounds/hr emissions
7000 grains/lb
Process flow rate = 7,000 cfm
Expected emission rate, grains/cf = 0.003
lbs/hr = 0.20
Yearly expected emissions = at 20 hrs/day, 6 days/week, 50 weeks/yr
tons/year = 0.60
_ The estimated yearly emissions are well below levels which would call for review of this project under District PSD requirements( 25 tpy PM, 15 tpy PM-10)
_ The expected emissions are well below the requirements of Regulation 1, Rule 420(e) which requires a 0.20 grains/cf not be exceeded.
_ Also Rule 420(e) limits the lbs/hr emission to less than specific amounts based upon process weight rate. The sawmill process produces greater than 60,000 lbs/hr of lumber throughput which is the maximum process weight rate allowance and yields allowable emission rate of 40 lbs/hr for the sawmill. This is the only air emission device at the sawmill, so this rate is not being exceeded.
Recommendation: Issue the ATC and review by EPA for Title V permit inclusion.

A. Sawmill
(1) Permit Number - NAC-328(Collector).
Name - Trimmer
I. BASIC EQUIPMENT - Multi-saw Trimmer for cutting green sawmill lumber to lengths. A 40 HP blower is used to pneumatically convey wood particles to a 4 foot 6 inch diameter cyclone collector(Cyclone C). The exhaust air from the collector is discharged directly to the atmosphere while the wood particles gravity feed to the planning mill storage bin.
II. CONTROL EQUIPMENT - None.
III EMISSIONS LIMITATIONS
A. Particulate Matter
1. Particulate loading -
a. The permittee shall not discharge particulate matter into the atmosphere in excess of 0.20 gr/acf of exhaust gas.
b. All permit units which are a part of the Sawmill shall not discharge particulate matter in total quantities exceeding 40 lbs/hr.
[Regulation 1, Rule 420(e) adopted 1/19/89 and SIP Rule 420(d)].
2. Visible emissions - see General Provisions, section L.
3. Fugitive Dust - see General Provisions, section L
IV. COMPLIANCE MONITORING
A. The following methods shall be used for determining compliance with the above emissions limitations:
1. Particulate Matter - The permittee shall perform at least once per permit term a source test by Oregon DEQ Method 8. A contractor shall be hired to perform such a test. An engineering evaluation will be allowed utilizing the District’s emission factors for collectors which provides grain loading vs. opacity(Figure I, page 26) in support of a test exclusion. Such exclusion will be granted should the evaluation indicate emissions are less than one-half the allowable particulate matter limit of Section III.A.1.a and less than Section III.A.1.b[Regulation 1, Rule 240].
2. Visible Emissions - Federal Method 9. The permittee shall perform a “Visible Emission Evaluation”(VEE) at least once per quarter while the trim saws are in operation. A CARB certified contractor or the District shall be hired to perform such an evaluation[Regulation 1, Rule 240(h)].
3. Fugitive Dust - The permittee shall conduct inspections of the basic equipment on a weekly basis(7 day schedule). Data availability from this manual recordkeeping shall be 90% of the actual operating time of the plant.
a. Any notable blow pipe or collector leak of exhaust gas prior to the discharge point to the atmosphere shall be repaired within 3 days upon detection.
b. Wood particles deposited on the roof of any building or elsewhere shall be removed within 3 days upon detection.
[Regulation 1, Rule 240(d)].
V. REPORTING AND RECORDKEEPING - see General Provisions, section F.
A. A log shall be maintained which specifies the initials of the person inspecting the system, date inspected, location of any leak found, and date of repair.
B. No monitoring other than indicated shall be required for this permit unit.
VI. OPERATING CONDITIONS - see General Provisions, section C.
A. The permittee shall not operate the system should the collector(s) become plugged which causes wood particles to be blown to the atmosphere. Once the system is found to be plugged, the permittee shall stop all pertinent process operations and remove the plug prior to further operation. Such system failures shall be reported to the District in accordance with Rule 540, Breakdown Procedures.
GENERAL PROVISIONS
These general provisions apply to all facilities or sources owned or operated by the permittee as detailed in this permit.
A. Fee Payment - The Permittee shall pay an annual permit fee and other fees as required in accordance with Regulation 1, Rule 300 of the District. Failure to pay these fees will result in forfeiture of this Permit to Operate. Operation without a permit subjects the source to potential enforcement action by the District and the US EPA pursuant to section 502(a) of the Clean Air Act as amended in 1990[40 CFR 70.6(a)(7); Regulation 5, Rule 670].
B. Inspection and Entry - Upon presentation of credentials and other documents as may be required by law, the permittee shall allow the District, CARB, EPA or an authorized representative to perform the following:
1. Enter upon the permittee’s premises where a regulated facility or emissions-related activity is located or conducted, or where records must be kept under the conditions of this permit.
2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this permit.
3. Inspect at reasonable times any facilities, equipment (including monitoring and air pollution control equipment), practices, or operations regulated or required under this permit.
4. Sample or monitor at reasonable times substances or parameters for the purpose of assuring compliance with the conditions of this permit.
[40 CFR 70.6(c)(2); Regulation 5, Rule 610(e)]
C. Facilities Operation
1. Operation under this permit must be conducted in compliance with all data and specifications included in the application which attest to the operator's ability to comply with District Rules and Regulations[Regulation 1, Rule 240(d)].

3. Operational Limit - This permit is valid for a maximum of 365 days per year at 24 hours per day[Regulation 1, Rule 240(d)].
D. Compliance
1. The permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Federal Clean Air Act and is grounds for enforcement action(including monetary civil penalties); for permit termination, revocation and reissuance, or modification; or for denial of an application for reissuance of the permit[40 CFR 70.6(a)(6); Regulation 5, Rule 610(g)].
2. The need to halt or reduce activity is not a defense. It shall not be a defense for a permittee in an enforcement action that it would be necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit[40 CFR 70.6(a)(6); Regulation 5, Rule 610(g)].
3. A pending permit action or notification of anticipated noncompliance does not stay any permit condition[Regulation 5, Rule 610(g)(5)].
4. The permittee shall furnish to the District, within a reasonable time, any information that the District may request in writing to determine whether cause exists for modifying, revoking and reissuing, or terminating this permit or to determine compliance with this permit.

These reports shall be due no later than July 15th and February 28th of each calendar year[Regulation 1 Rule 240(d)].
G. Transfer of Ownership -In the event of any changes in control or ownership of these facilities, this permit together with its terms and conditions shall be binding on all subsequent owners and operators. The permittee shall notify the succeeding owner and operator of the existence of this permit and its conditions by letter, a copy of which shall be forwarded to the District. Such permit transfer shall occur by application through the District[Regulation 1, Rule 240(j)].
H. Reopening for Cause
1. This permit may be modified, revoked, reopened, reissued, or terminated for the following reasons:
a. Additional requirements under the federal Clean Air Act become applicable to the facility for which three or more years remain on the original term of the permit. Such a reopening shall be completed not later than 18 months after promulgation of the applicable requirement. No such reopening is required if the effective date of the requirement is later than the date on which the permit is to expire.
b. The District or EPA determines that the permit contains a material mistake made in establishing the emissions standards or limitations, or other requirements of the permit.
c. The District or EPA determines that the permit must be revised or revoked to assure compliance with the applicable requirements. [40 CFR 70.7(f); Regulation 5, Rule570]
2. The reopening of this permit for a change to be implemented for a specific permit unit will be allowed without the need to reopen the entire permit and all permit units. Should a general condition be changed, all the associated permit units affected would be reopened[Regulation 1, Rule 240(d)].
3. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or of a notification of planned changes or anticipated noncompliance does not stay any permit condition[40 CFR 70.6(a)(6)].
I. Property Rights - This permit does not convey any property rights of any sort, or any exclusive privilege[40 CFR 70.6(a)(6)].
J. Permit Renewal and Expiration - This permit is effective on the date of issuance and will expire in five years and must be renewed every five years thereafter. Permit expiration terminates the permittee’s right to operate unless a timely and complete renewal application is submitted. For renewal of a permit, the designated representative shall submit a complete District application no earlier than 18 months and no later than 6 months before the expiration date of the current permit[40 CFR 70.5(a); Regulation 5, Rule 405(b)].
K. Permit Modification - The permittee shall submit an application for a minor or significant permit modification in accordance with District Regulation 5[40 CFR 70.5(a); Regulation 5, Rule 405].
L. Prohibitions - These limitations apply to all emissions sources at the permittee’s facility unless more specific and limiting requirements are listed for a individual permitted emissions unit in this permit.
1. Public Nuisance - The permittee shall not discharge such quantities of air contaminants or other material which cause injury, detriment, nuisance or annoyance to any considerable number of persons or to the public or which endanger the comfort, repose, health or safety of any such persons or the public or which cause or have an natural tendency to cause injury or damage to business or property[H&S 41700].
2. Visible Emissions - The permittee shall not discharge into the atmosphere from any source whatsoever any air contaminant for a period or periods aggregating more than three (3) minutes in any one hour which is as dark or darker in shade as that designated as No. 2 on the Ringlemann Chart, as published by the United States Bureau of Mines; or of such opacity as to obscure an observer’s view to a degree equal to or greater than Ringlemann 2 or forty (40) percent opacity[Regulation 1, Rule 410(a)].
3. Fugitive Dust Emissions - The handling, transporting, or open storage of material in such a manner which allow unnecessary amounts of particulate matter to become airborne, shall not be permitted. Reasonable precautions shall be taken to prevent particulate matter from becoming airborne[Regulation 1, Rule 430].
4. Sulfur Oxide Emissions - The permittee shall not discharge into the atmosphere from any single source of emissions whatsoever sulfur oxides, calculated as sulfur dioxide (SO2) in excess of 1,000 ppm[Regulation 1, Rule 440].
5. Circumvention - The permittee shall not construct, erect, modify, operate, or use any equipment which conceals an air contaminant emission, which would otherwise constitute a violation of the limitations of this permit, unless the operation or use of said equipment results in a significant reduction in the total emission of air contaminants[Regulation 1, Rule 400(b)].
6. Regulation 2, Open Burning Procedures - The permittee shall not ignite or cause to be ignited or suffer, allow or maintain any open outdoor fire for the disposal of rubber, petroleum or plastic wastes, demolition debris, tires, tar paper, wood waste, asphalt shingles, linoleum, cloth, household garbage or other combustible refuse; or for metal salvage or burning of motor vehicle bodies except as provided in Rule 2-102, Exemptions[Regulation 2].
