Project Description
An Administrative Amendment to Approval Order DAQE-981-96, dated October 30, 1996, was
conducted in 2022 as part of a 10-year review. As part of the 10-year review, rule references were
renumbered, the equipment list was moved, and the text of each rule and condition were modified to
reflect the current language and formatting. As a result of the review, Feller Stone Incorporated was
issued Approval Order DAQE-AN109020003-22, dated July 30, 2022.

Dear Josh Feller,

Re: Engineer Review - 10-Year Review and Permit Updates:
Administrative Amendment to Approval Order DAQE-AN109020003-22 to Correct Stack
Testing Language
Project Number: N109020004

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. Feller Stone
Incorporated should complete this review within 10 business days of receipt.

Feller Stone Incorporated should contact Christine Bodell at [phone] if there are questions or
concerns with the review of the draft permit conditions. Upon resolution of your concerns, please email
Christine Bodell 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 Feller Stone Incorporated does not respond to this letter within 10 business days, the project will move
forward without source concurrence. If Feller Stone Incorporated has concerns that cannot be resolved
and the project becomes stagnant, the DAQ Director may issue an Order prohibiting construction.

Testing Language

Project Description
An Administrative Amendment to Approval Order DAQE-981-96, dated October 30, 1996, was
conducted in 2022 as part of a 10-year review. As part of the 10-year review, rule references
were renumbered, the equipment list was moved, and the text of each rule and condition were
modified to reflect the current language and formatting. As a result of the review, Feller Stone
was issued Approval Order DAQE-AN109020003-22, dated July 30, 2022.

The newly updated 2022 AO omits language stating that no initial stack testing for each baghouse
is required. The 2022 AO also omits language stating that the source is required to stack test only
if directed by the Director. This language is being added back into the AO through this
administrative amendment.

PERMIT HISTORY

When issued, the approval order shall supersede (if a modification) or will be based on the
following documents:

Supersedes AO DAQE-AN109020003-22 dated July 30, 2022

REVIEWER COMMENTS

1. Comment regarding Administrative Amendment:
The source is not modifying and/or installing any new equipment. There are no changes to the
emission estimates at this time.

A condition specifying the frequency requirements for the baghouse stack testing has been added to
the updated AO. This condition was unintentionally omitted during a 2022 10-Year Review. [Last
updated January 10, 2024]

2. Comment regarding NSPS Applicability:
40 CFR 60 NSPS Subpart OOO applies to non-metallic mineral processing plants that commence
construction, modification or reconstruction after August 31, 1983. The crusher was constructed in
1965; therefore, NSPS Subpart OOO does not apply to this facility.
[Last updated January 10, 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.
4. Any Title IV affected source.

This facility is not a major source, a Title IV source, nor subject to NESHAP/NSPS regulations.
Thus, this facility is not subject to Title V. [Last updated January 10, 2024]
