either be evaporated, used during the initial mixing of the compost, used for dust <br />control, pumped to the on-site impoundmentleachate evaporat ion pond , or <br />transported to a municipal treatment works depending on the quality and quantity of <br />collected water. Water used in the initial mixing of the compost will bring the water <br />content of the compost to proper levels and will eliminate the potential for pathogen <br />regrowth in the active compost. It is anticipated that the proposed retention pond <br />will provide adequate process water supply. <br />There are three agriculture water wells and one domestic well at the site. One well. <br />located near the main entrance facility was drilled to a depth of approximately 135 <br />feet and groundwater occurs at a depth of approximately 70 feet. The well was likely <br />installed before the opening of the landfill. having been previously used for <br />agricultural purposes. It is pumped at a rate of approximately 1.500 gallons per <br />minute (gpml at a maximum frequency of approximately 27 times in a typical working <br />day. Another well is located south of the South Fork of South Littlejohn's Creek in the <br />southeast corner of the RRF and Compost Facility area. and has a capacity of 500 <br />gpm. The third well is located along the northern boundary of the former Austin Road <br />Landfill. This well was installed in 1972 and has a production of approximately 60 <br />gpm. The fact that groundwater flow near the existing Forward Landfill is not <br />modified by pumping from this well suggests that it is screened in a confined unit <br />below the uppermost groundwater units that are monitored at the site. One domestic <br />well. is located along the eastern boundary of the site. just south of the entrance to <br />the Compost Facility/RRF. The locations of the wells located in the Compost <br />Facility/RRF area is shown on Figure 1. If necessary, process water may be obta ined <br />from two on site production we l ls: a 1,000 gpm we ll neaF the landfill entranse <br />facilities and a 20 gpm ','"el l near the RRF building. A water tan l< will a lso be in the <br />Compost Facility located on the southern portion of the Forward Landfill property. <br />Since water will only be added to the compost to maintain adequate internal <br />moisture, significant leachate generation is not anticipated. <br />There is no on-site wash water generated. Therefore, no wastewater is generated; <br />however, should some be generated it will be collected and discharged to the Class II <br />surface impoundment utilized as a leachate pond. <br />3.8 MATERIAL PROCESSING, HANDLING, AND STORAGE PRACTICES <br />3.8.1 ProceSSing <br />3.8.1.1 Feedstock <br />The Compost Facility will operate between the hours of 6:00 a.m. to 6:00 p.m. <br />Monday through Saturday and is f closed on Sunday ~ and on Christmas Day and New <br />Years Dayfour ho lidays). During the week, the RRF accepts materials up until 4:00 <br />p.m. in order to process andlor, cleanup or both prior to 6:00 p.m. Odors are <br />controlled by processing the material and removing the material as soon as possible <br />after they ha'/e beenbeing brought into the RRF. Odors are not anticipated from <br />storage residencethe materials since residueit will be stored for no more than 48 <br />hours. <br />Forward Compost Facil ity -OIMP 8 SWT Engineering <br />z:\projects\aliied waste \forward \resource recovery facility\5 yr permit rvw 2013-14\rcsi 2014\appendices\app e-oimp\oimp <br />text.doc; 5/16/2014
