Facility ID Facility Description Facility Location Permit Number Permit Title Proposed Permitting Action Date Issued
364 Mountain Pass Mine 67750 Bailey Road, Mountain Pass, CA 92366 B015488 ORE SORTING SYSTEM The proposed new equipment units include one ore sorting system and one primary crushing system which are sources of PM10 and HAP/TAC. AP-42 Chapter 11.19.2 emission factors for Crushed Stone Processing and Pulverized Mineral Processing were used rather than Chapter 11.24 Metallic Mineral Processing because the metallic mineral content of the ore is low (<10%) with the majority of the ore comprised of non-metallic minerals. The low rare earth metal content is analogous to the ore processed at gold mines. The determination that non-metallic emission factors are more representative is substantiated by the May 31, 2017 document Guidance on Emission Factors for the Mining Industry published by the Nevada Division of Environmental Protection, Bureau of Air Pollution Control. 05/11/2026

4632 Brother's Collision Center 16660 Juniper Street, Hesperia, CA 92345 S015446 SPRAY BOOTH, AUTOMOTIVE Obtain an Authority to Construct permit for a new automotive spray booth. This Permit Unit has a PTE less than 25 pounds per day of any Nonattainment Air Pollutant when operated in accordance with the proposed permit conditions. This Facility has a PTE less than 25 tons per year for VOC and less than 15 tons per year for PM10; therefore, BACT is not required, pursuant to District Rule 1303(A). See Applicable Rules for a detailed discussion of NSR/T-NSR. This spray booth is not located within 1000 feet any K-12 school; therefore, H&SC 42301.6 Public Noticing will not be required.

364 Mountain Pass Mine 67750 Bailey Road, Mountain Pass, CA 92366 C011576 CAUSTIC SCRUBBER, DISSOLUTION PROCESS The Dissolution Process under District permit B011575 is a source of HAP/TAC emissions only. Emissions include HCl and Cl2 and are controlled by the Dissolution Scrubber under District permit C011576. There are no combustion sources nor material handling associated with the Dissolution Process. The Dissolution Process is downstream of the Leach Process under B011248 and upstream from Iron Uranium Separations under B011542. The proposed permitting action replaces the existing scrubber under C011576 with a new scrubber. The exhaust concentration limits are not changed by this permit change request however the rated exhaust flow increases from 1000 acfm to 2000 acfm PPMV leading to higher hourly PTE but not an annual increase because this facility operates under facility wide emissions limitations which are not changed by the proposed scrubber replacement. 05/11/2026
364 Mountain Pass Mine 67750 Bailey Road, Mountain Pass, CA 92366 B011542 IRON URANIUM SEPARATIONS PROCESS Paid permit change request to modify existing permit B011542 for the iron and uranium separations process. This process yields HCl emissions no other HAP/TAC or criteria pollutants. The changes to the permit add one ion exchange column with is fully enclosed and does not vent to atmosphere and an update of permit conditions to align with recently issued facility permits. The 10 ton of any single HAP/25 ton of any combination of HAP facility emissions limitations are the emissions unit limitations for HAP. The referenced emission limitations are not changed by the permit updates. 05/11/2026
