Valero’s Draft permit suggests the emission increases do not
trigger New Source Review.
The Draft permit states after the Flare Gas Recovery System
is completed the flare sulfur dioxide emissions will decrease from the current
permitted level of just under 700 tons per year to a proposed cap of 182 tons
per year sulfur dioxide. Given Valero’s Meraux refinery is located in an area
nonattainment for sulfur dioxide, Valero should invest in the appropriate pollution
controls before expanding its hydrocracker unit.
Temporary Road Closures expected Tuesday May 28 2013 from 9am to 5pm as Valero Energy moves a reactor unit, which is part of its hydrocracker revamp project in Meraux Louisiana. Sheriff's deputies will be utilized for traffic control.
Valero Energy Corporation is expanding its hydrocracker unit's processing capacity to produce more low sulfur distillates like jet fuel and diesel as part of its plan to become one of the ""first North American refiners to produce as much distillate as gasoline. "" according to a May 17 2013 Platts article http://www.platts.com/RSSFeedDetailedNews/RSSFeed/Oil/21049620
Throughout its refining locations, ""Valero plans to implement a one-to-one gasoline-to-distillates ratio by around 2015, after more than $3 billion worth of projects go live to increase the company's distillate production, the company said."" (Platts)
Valero's Meraux refinery hydrocracker revamp project will increase distillate capacity to 58,000 barrels per day (up from 34,000 barrels per day). Installation is expected late 2014 (Platts)

Valero St Bernard Parish Refinery Nov 5 2012 final permit (a minor modification just under the Clean Air Act New Source Review PSD thresholds for review for more stringent pollution controls).
Hydrocracker Unit Revamp
SO2 increase 39.34 tons per year (the PSD threshold is 40 tpy SO2)
VOCx increase 33.8 tpy (the PSD threshold is 40 tpy VOCs)
Hydrogen sulfide emissions will nearly double from 4.20 to 7.65 (tons per year).

Valero St Bernard Parish refinery to implement the Hydrocracker Unit (HCU) Revamp Project and other permit/revisions/reconciliations. The project's emissions are all just under the PSD Review threshold. The emission reductions are from the EPA consent decree.
The HCU Revamp Project will increase the followings:
The volume of the HCU reactor,
The utilization (normal operating rates) of the HCU and NHT heaters,
The sulfur loading at the SRU No. 2 and SRU No. 3 by modifying the front end of the SRU to accommodate additional sour water stripper gas from the expanded HCU,
The circulation rate of the Area 6 Cooling Tower to 25,000 gpm by installing a new cell and a new circulation pump,
The middle distillate product throughput at the river loading dock and at the tank farm,
The fugitive component counts due to the project.

Application 10/5/2012 VALERO MERAUX hydrocraker unit revamp
LDEQ EDMS document 8567096 dated 10/05/2012
Valero's application to construct the hydrocracker unit revamp (HCU revamp project) as a minor modification.Total VOC emissions will increase significantly. VOC's include n-Hexane, Benzene, 2,2,4-Trimethylpentane, Toluene, Ethylbenzene, Xylenes, and Naphthalene. Increased VOCemissions from the cooling tower is more than four times from 3.68 to 16.03 and VOCs from the river dock loading will increase from 9.40 to 15.41 (tons per year). Sulfur emissions are reported to decrease, although some of the decreased sulfur emissions maybe due to the EPA consent decree with Murphy Oil.
