C <br />Construction & Demolition/Inert Debris Facility Report <br />Tracy Material Recovery and Transfer Facility <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 />0 Drainage 17407. 2 <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 050813 revised <br />
