Public Notice Start Date: April 30, 2025	

PCC GulfChem Corporation (PCC GulfChem) is proposing to locate at 7685 Kiln Delisle Road in Pass Christian, Harrison County, Mississippi. PCC GulfChem plans to design, build, and operate a chlor-alkali facility (SIC Code: 2812). PCC GulfChem requests an Optional Pre-Permit Construction approval from the Mississippi Department of Environmental Quality (MDEQ) as allowed by the Mississippi Air Permit Regulations 11 Miss. Admin. Code Pt. 2, R. 2.15.B.

PCC GulfChem will import salt to make brine to manufacture liquid chlorine (Cl2) and be able to produce hydrochloric acid (HCl) and bleach (NaOCl) byproducts. PCC GulfChem will consist of twelve (12) emission sources in a closed-loop system that include particulate matter (PM), nitrogen oxide (NOx), minimal Cl2, and minimal HCl emissions. The emissions from this project will be below the Prevention of Significant Deterioration (PSD) significant levels for a named source as specified in the Mississippi Regulations for PSD of Air Quality, 11 Miss. Admin. Code Pt. 2, Ch. 5, and more specifically in 40 CFR Part 52.21. The facility will be classified as a true minor source under the PSD construction permitting program for all pollutants. The facility will trigger the need of a Permit to Construct because potential criteria pollutant emissions will exceed the Permit to Construct thresholds. 

Persons wishing to comment upon or object to the proposed request are invited to submit comments in writing to Chief, Environmental Permits Division at the Permit Board’s address shown above no later than ten (10) days from the date of publication of this notice. All comments received or postmarked by this date will be considered in the determination regarding the Pre-Permit Construction approval. After receipt of public comments and thorough consideration of all comments, MDEQ will formulate its recommendations regarding Pre-Permit Construction approval.

Additional details about the application are available by writing or calling the Public Records Request Officer at the above Permit Board address and telephone number or by completing the form at the following website:
