4709 Lynx Cat Mountain Quarry Operations, LLC 1 Lynxcat Road, Hinkley , CA 92347 B015602 DIESEL IC ENGINE, PORTABLE* GENERATOR Lynx Cat Mountain Quarry Operations, LLC, Facility 4709 engages in aggregate processing and is located in Hinkley. The facility has numerous PERP units which are required to have District permits by April 9, 2027. The facility purchased the proposed generator and had begun operating it to power their office trailer without District permit nor PERP registration. They were issued a Notice to Comply to submit a permit application or obtain a PERP registration. Because the use of PERP will only be allowed until April 9, 2027 the facility opted to apply for a District permit. The facility has applied to permit and operate a Tier IVF 86.5 bhp Isuzu engine that will be used to power the portable generator. While this engine may operate at different locations within the facility, it meets the more stringent emission limits set forth in the Stationary ATCM, 40 CFR 60 Subpart IIII and District Rule 1160 and therefore is not required to move within 365 days of commencing operation. 08/13/2026
