2023 Ozone Reasonable Available Control Technology Analysis
Purpose
The Northern Wasatch Front is expected to be reclassified by the Environmental
Protection Agency (EPA) as serious nonattainment for ozone in February 2025. In
anticipation of this reclassification the Utah Division of Air Quality (UDAQ)
requested, by a letter dated May 31, 2023, a reasonable available control
technology (RACT) analysis for nitrogen oxides (NOx) and volatile organic
compound (VOC) emitting units. This document provides a detailed top down
RACT analysis for the NOx and VOC emitting units at the Chevron Products
Company - Salt Lake Refinery.
1.1 Background
The Chevron refinery processes various crude oils and lesser quantities of other
hydrocarbon feedstocks to produce transportation fuels, petroleum coke, sulfur,
and various byproducts. The refinery operates 24 hours per day, 7 days per week,
52 weeks per year.
The refinery uses three general processes to transform crude oil into refined
petroleum products: distillation, conversion, and purification. These processes
occur in nine primary process units and various ancillary units. Distillation
separates these raw materials into different fractions based upon their boiling point
ranges. Some of the lighter factions are blended directly into products. Heavier
hydrocarbons are further converted by processes that may combine, rearrange, or
break molecules and form new hydrocarbon compounds. Products are then
purified by removing and transforming compounds, such as hydrogen sulfide into
useful compounds. Ultimately, components produced from the various refining
processes are blended together according to product specifications. Products
produced by the refinery include: fuel gas (all fuel gas produced is consumed by
the refinery), propane, motor gasoline, jet fuel, diesel fuel, gas oil, coke and liquid
sulfur.
The Chevron refinery currently operates under two approval orders, DAQE-
AN1 011901104-22 and DAQE-AN1 011901106-22. Additionally, a Title V Operating
Permit Application was submitted to UDAQ on January 31, 2020.
Chevron refinery submitted a RACT analysis on January 31, 2023 for the Ozone
Moderate State Implementation Plan (SIP). The purpose of this analysis is to
provide UDAQ with the information requested in the May 31, 2023 letter. Based on
the Chevron Refinery Moderate Ozone SIP Final RACT Determination, sent via e-
mail on August 21, 2023, additional RACT controls are economically infeasible for
Chevron's Refinery. The Air Quality Board accepted the technologies currently
utilized at the Chevron Refinery as RACT in the Moderate Ozone SIP, which was
approved on September 12, 2023.

4 RACT Analysis for Significant Source
Categories
4.1 Introduction
UDAQ has requested a top down RACT analysis, which includes the following
steps:
1) Identify all reasonable available control technologies
2) Eliminate technically infeasible control technologies
3) Rank remaining control technologies based on capture and control efficiencies
4) Evaluate remaining control technologies on economic, energy, and
environmental feasibility
5) Select RACT
4.2 Identify Reasonable Available control Technologies
The following table displays control technologies by source category.
