Vulcan Materials

Ready-mix concrete (RMC) refers to concrete that is specifically manufactured for construction projects and supplied to the site as a single product. RMC is a mixture of Portland (or other) cements, water, and aggregates: sand, gravel, or crushed stone. The materials needed to assemble the RMC elements will be imported to the site via trucks entering the site off Tower Road and combined in the plant on site to create the RMC. Delivery/hauling trucks will then exit the site via the same driveway location off Tower Road. The RMC plant would have a capability of producing up to 65,000 cubic yards of concrete each year. To assemble the materials for delivery, the site will be improved with the following equipment and structures: • Portable Ready Mix Concrete Plant • Office Trailer • Ready Mix Truck Concrete Washout Area • Front End Loader (Heavy Equipment) • Aggregate Block Bunkers to Separate Materials The site will feature ingress/egress off Tower Road. An asphalt paved and/or concrete road will connect the areas where concrete trucks will be traversing the site, the rest of the site will be compacted earth.The concrete trucks will be parked on site overnight and when not in use. The site will also be improved with stormwater drainage infrastructure such as culverts and sediment ponds. Typical operational days will be Monday through Saturday, although depending on concrete demand it is possible that the site will be in operation seven (7) days per week. The maximum number of employees on site will be eight (8.) Typical operational hours will be from 5:00am – 5:00pm, although depending on concrete demand it is possible that the site will be in operation 24 hours per day. The facility will be transferring an existing operating permit (#30422) from the Bay Area Air Quality Management District (BAAQMD) from a plant in Petaluma to this facility. No other licenses and/or approvals from outside agencies (Special District, Regional, State, Federal) will be needed. The application requires review and approval from the Napa County Airport Manager. The site will be connected to American Canyon water and sewer.
