Dear Mr. Harrington:

RE: Revocation of Approval Order DAQE-AN147940001-13 dated August 26, 2013
Project Number: N147940002

The Division of Air Quality (DAQ), received your email on March 3, 2025, requesting that the
above-referenced approval order (AO) be revoked.

RPS Composites, formally RPS Composites-Utah, Inc., has informed the DAQ that it no longer owns or
operates the reinforced fiberglass manufacturing plant located at 615 West 900 North, North Salt Lake in
Davis County.

DAQ has revoked the above-referenced AO effective as of the date of this letter. As authorized by the
Utah Legislature, the fee for revoking an AO is the actual time spent by the review engineer and all other
staff on the project. Payment should be sent to the DAQ upon receipt of the invoice.

If you have any questions, please contact Christine Bodell, who can be reached at [phone] or
[e-mail].

Sincerely,

Abstract

RPS Composites-Utah Inc. operates a reinforced fiberglass manufacturing plant in Woods Cross in Davis
County. The company has submitted a request to relocate all manufacturing operations from Woods
Cross to North Salt Lake City. Davis County is a maintenance area of NAAQS for ozone and is a
nonattainment area for PM2.5. NSPS, NESHAP and MACT regulations do not apply to this source. Title
V of the 1990 Clean Air Act does not apply to this source.

The emissions, in TPY, will change as follows: PM10 - 0.01, NOx + 0.01, CO + 0.01, VOC + 0.21 and
HAPs - 0.81. The changes in emissions will result in the following, in TPY, PTE totals: PM10 = 0.03,
PM2.5 = 0.01, NOx = 0.06, CO = 0.05, VOC = 14.51, HAPs = 11.29 and CO2e = 66.

This air quality AO authorizes the project with the following conditions and failure to comply with any of
the conditions may constitute a violation of this order. This AO is issued to, and applies to the following:

including associated air pollution control equipment, in a manner consistent with good air
pollution control practice for minimizing emissions. Determination of whether acceptable
operating and maintenance procedures are being used will be based on information available to
the Director which may include, but is not limited to, monitoring results, opacity observations,
