Project Description
The source has proposed to replace the ultrasonic vapor degreaser listed under II.A.10 in the AO
DAQE-AN104860010-15 with two (2) small vapor degreasers. Emissions from the new degreasers will
vent through the same existing ventilation system to the atmosphere. This replacement will not increase
the potential to emit any air pollutant or cause emissions of any new air pollutant. Therefore, the
replacement meets the applicability listed in R307-401-12, Reduction in Air Pollutants. This
administrative amendment will update the AO to include the two (2) small vapor degreasers.

SUMMARY OF EMISSIONS

The emissions listed below are an estimate of the total potential emissions from the source. Some
rounding of emissions is possible.

[e-mail] Dear Thomas Allen,
Re: Engineer Review: Administrative amendment to Approval Order DAQE-AN104860010-15 to Replace the Ultrasonic Vapor Degreaser Project Number: N104860011 The DAQ requests a company representative review and sign the attached Engineer Review (ER). This ER identifies all applicable elements of the New Source Review (NSR) permitting program. L3Harris EDO Western Corporation should complete this review within 10 business days of receipt. L3Harris EDO Western Corporation should contact Mr. Enqiang He at [phone] if there are
questions or concerns with the review of the draft permit conditions. Upon resolution of your concerns, please email Mr. Enqiang He at [e-mail] the signed cover letter. Upon receipt of the signed cover letter, the DAQ will prepare an Approval Order (AO) for signature by the DAQ Director. If L3Harris EDO Western Corporation does not respond to this letter within 10 business days, the project will move forward without source concurrence. If L3Harris EDO Western Corporation has concerns that
cannot be resolved and the project becomes stagnant, the DAQ Director may issue an Order prohibiting construction. Approval Signature _____________________________________________________________ (Signature & Date)

Administrative amendment to Approval Order DAQE-AN104860010-15 to Replace the Ultrasonic Vapor Degreaser Project Description The source has proposed to replace the ultrasonic vapor degreaser listed under II.A.10 in the AO DAQE-AN104860010-15 with two (2) small vapor degreasers. Emissions from the new degreasers will vent through the same existing ventilation system to the atmosphere. This replacement will not increase the potential to emit of any air pollutant or cause emissions of any
new air pollutant. Therefore, the replacement meets the applicability listed in R307-401-12, Reduction in Air Pollutants. This administrative amendment will update the AO to include the two (2) small vapor degreasers.
EMISSION IMPACT ANALYSIS This administrative amendment is for a reduction in air pollutants; there will be no emission increases.
Therefore, modeling is not required at this time. [Last updated October 2, 2024]

REVIEWER COMMENTS
1. Comment regarding Reduction in Air Pollutants: The source has proposed to replace the ultrasonic vapor degreaser listed under II.A.10 in the AO DAQE-AN104860010-15 with two (2) small vapor degreasers. Emissions from the new degreasers will vent through the same existing ventilation system to the atmosphere. This replacement will not increase the potential to emit of any air pollutant or cause emissions of any new air pollutant. Therefore, the replacement meets the applicability listed in R307-401-12, Reduction in Air Pollutants. This administrative amendment will update the AO to include the two (2) small vapor degreasers. The new vapor degreasers are subject to the requirements in R307-335; therefore, II.B.2.b is added to this AO. [Last updated November 19, 2024] 2. Comment regarding Federal standard applicability:
The following Federal standards were determined to apply to the emergency generator engine in the previous review: NSPS (Part 60), IIII: Standards of Performance for Stationary Compression Ignition Internal Combustion Engines. MACT (Part 63), ZZZZ: National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines. [Last updated October 2, 2024] 3. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following: 1. Any major source; 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act,
Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants; or 4. Any Title IV affected source. This facility is not a major source and is not a Title IV source. It is subject to NSPS Subpart IIII and MACT Subpart ZZZZ requirements. However, the Federal standards specifically exempt the source

Engineer Review N104860011: L3Harris EDO Western Corporation November 19, 2024 Page 13
from the obligation to obtain a Title V permit, provided that the source is not required to obtain the permit for a reason other than being an area source under the Subparts IIII and ZZZZ. Therefore,
Title V is not required for the source. [Last updated October 2, 2024]

(c) no additional types of air pollutants are emitted as a result of the replacement;
(d) the process equipment or pollution control equipment is identical to or functionally equivalent to the replaced equipment;
(e) the replacement does not change the basic design parameters of the process unit or pollution control equipment;
(f) the replaced process equipment or pollution control equipment is permanently removed from the stationary source, otherwise permanently
disabled, or permanently barred from operation;
(g) the replacement process equipment or pollution control equipment does not trigger New Source Performance Standards or National
Emissions Standards for Hazardous Air Pollutants under 42 U.S.C. 7411 or 7412; and
(h) the replacement of the control apparatus or process equipment does not violate any other provision of Title R307.
(2) Replacement-in-Kind Procedures.
(a) In lieu of filing a notice of intent under Section R307-401-5, the owner or operator of a stationary source shall submit a written notification
to the director before replacing the equipment. The notification shall contain a description of the replacement-in-kind equipment, including the control
capability of any control apparatus and a demonstration that the conditions of (1) above are met.
(b) If the replacement-in-kind meets the conditions of (1) above, the director will update the source's approval order and notify the owner or
operator. Public review under Section R307-401-7 is not required for the update to the approval order.
