What is the purpose of this permit? Construction Permit C-0036-22-0016-V will allow construction of new equipment to allow for automated transfer of materials instead of manual transfer, construction of equipment to replace older equipment, and piping to allow operation through multiple control chains.
-
Will this permit increase pollution? The equipment permitted in Construction Permit C-0036-22-0016-V has potential PM emissions of 3.20 tons per year, potential HAP emissions of 0.00544 tons per year, potential NOx emissions of 2.40 tons per year, and potential VOC emissions of 6.04 tons per year. The permit will continue to limit plantwide emissions below major source thresholds (100 tons per year of criteria pollutants, 10 tons per year of single HAPs, and 25 tons per year of total HAPs).
-
How does this impact STAR risk? Since the original public notice was issued, the District determined that the plantwide risk should have been represented to include the operational limit on the heat treaters to not allow simultaneous operation to their alternate control schemes while processing Hexavalent Chromium (Cr(VI)) products. This corrects the plantwide risk from 2.077 to 1.41.
-
Does this facility have a history of non-compliance? The last notice of violation was in 2022 and addressed with Agreed Board Order 22-01. This violation was for having changes in the plant’s operation that should have been reported earlier. See the Compliance History table in the Statement of Basis, page 14.
-
Where can I find out more? Additional information, including equipment descriptions, potential emissions, and applicable rules, are summarized in the Statement of Basis. The Draft Permit details the application of these rules to the equipment and includes the monitoring, recordkeeping, and reporting that the District believes is necessary to demonstrate compliance.
