Document Description
The Triangle Rock Products Los Banos facility currently uses and maintains two existing dry creek crossings over Los Banos Creek. The dry creek crossings are permitted via an existing Streambed Alteration Agreement (SAA; File No. R4-2001-0098D). The creek crossings can only be used when the creek is dry pursuant to the terms of the existing SAA. Periodic water releases from Los Banos Creek Detention Dam between September and March close the creek crossings and cut off vehicle access between resource recovery sites and the processing facility when the road is inundated by creek flow. The proposed Project will install two culvert pipes at the south crossing and three culvert pipes at the north crossing to divert flow under the improved access road to facilitate year-round vehicle use of the road. The improved road crossings will facilitate continuous vehicle transport over Los Banos Creek from permitted and existing mineral resource recovery sites to the processing plant at all times of the year. While the Project will facilitate continuous transport over Los Banos Creek, the total number of truck trips would not be increased as facility production is limited by Triangle Rock’s air permits. As an ancillary benefit, the Project will also
facilitate permitted and existing water management activities in the region.
