Eco Services Operations Corporation-Issuance of Permit to Operate for alteration to increase stack height of S-1 Sulfuric Acid Plant, (AD App 753382).

The Bay Area Air Quality Management District is issuing a Permit to Operate for Eco Services Operations Corporation to perform a minor alteration to the S-1 Sulfuric Acid Plant located in Martinez, California. The project involves increasing the stack height by 7 feet and 1 inch and relocating the Reference Method test ports by replacing the existing stack with a new one of the same inner diameter. This action is a direct response to Notices of Violation regarding EPA 40 CFR Part 60, Appendix B, Performance Specification 2, and is designed to ensure compliance with EPA Method 1 and Performance Specification 2 for emissions monitoring. The alteration is classified as a ministerial action and is exempt from the California Environmental Quality Act under Public Resources Code section 21080(b)(1) and CEQA Guidelines section 15268(a) due to the negligible nature of the expansion. There are no proposed changes to the process, throughput, control equipment, or emissions levels at the S-1 plant, which includes components such as the furnace, waste heat boiler, and A-11 Ammonia Scrubber. The permit was posted on August 12, 2026, and the project is managed by Air Quality Engineer Christopher Ablaza and Environmental Manager Neil Baranik.
