Construction &Demolition/Inert Debris Facility Report <br /> Tracy Materia/Recovery Facility and Transfer Station <br /> 30703 S. MacArthur Drive, Tracy, California 95377 <br /> ® The operator maintains several hydrants disbursed throughout the facility, as part <br /> of the onsite water supply system which includes a 150,000 gallon water tank <br /> (fed by onsite wells) and pressurization equipment. Hoses, also used onsite for <br /> dust suppression purposes, are available to suppress small fires, should they <br /> occur. Process water used for dust or fire control or other operational <br /> requirements, and will be minimized only to what is necessary. Surface water <br /> runoff, including all process water, will be directed to a onsite retention basin by <br /> use of grading design and drainage ditches, where it will be properly treated, if <br /> necessary, to eliminate potential environmental impacts. <br /> Cleaning [14 CCR 17407.2] <br /> The facility will be maintained regularly by site personnel. A daily site walk will be <br /> conducted by facility personnel to identify areas of the entrance, site and <br /> buildings in need of cleaning or repair. Loose materials and litter will be removed <br /> daily from operations areas. The access area will be policed daily to prevent the <br /> offsite migration of waste materials; any illegal dumping in the immediate area <br /> along MacArthur Drive will be cleaned up by site personnel. The facility uses 40- <br /> cubic-yard roll-off boxes to storage reject materials and on-site litter and residues <br /> that result from site maintenance. The entrance area of the facility will be <br /> routinely cleaned by a street sweeper to prevent offsite tracking of sediment. <br /> Drainage Control [14 CCR 17407.3] <br /> The facility operates on asphalt concrete or concrete pad that facilitates control of <br /> onsite drainage to and prevent the offsite migration of contact water and erosion. <br /> Surface water runoff is directed to an onsite retention basin by use of grading <br /> design, drain pipes, and drainage swales. Drainage swales have been designed <br /> and installed to prevent erosion and promote safe operations and access to the <br /> facility. <br /> Process water will be used for dust or fire control or other operational <br /> requirements, and will be minimized only to what is necessary. <br /> Dust Control [14 CCR 17407.4] <br /> The operator maintains several hydrants disbursed throughout the facility, as part <br /> of the onsite water supply system which includes a 150,000 gallon water tank <br /> (fed by onsite wells) and pressurization equipment. Manual watering of materials <br /> is done to control dust as needed. The watering is done using handheld hoses. <br /> The material is not sprayed so much as to generate runoff from the debris piles. <br /> Portable crushing or grinding equipment used on site is equipped with water <br /> sprays to control dust during processing. Load checking activity will prevent <br /> hazardous materials from being processed by crushing or grinding equipment. <br /> Processing operations and loading or unloading of trucks will be monitored <br /> 17 170.18 CDI FacReport 05081313 <br />
