2020 Solid Waste and Moderate <br />Risk Waste Management Plan Update <br /> <br />AX0304191054PDX 7-13 <br /> Pond 4/East Leachate Lagoon <br />Kittitas County Solid Waste accepts liquid waste (septage) from permitted haulers within the County. <br />7.9.2 Existing Conditions <br />The two septage LWELs (Ponds 1 & 2) are constructed in accordance with WAC 173.308-310 Biosolids <br />Management Permit BT-9208. The lagoons, designed with a thirty-mil reinforced artificial liner, are <br />designed to be used in tandem. When one lagoon reaches capacity, the contents evaporate while the <br />second lagoon is put into use. According to the Operations Plan, sludge is dried to a semiliquid state, <br />mixed with lime to stabilize the pH, and then land-applied at the Ryegrass facility in accordance with the <br />permit. <br />Pond 3/West Leachate Lagoon operates under WAC173-216 Wastewater Discharge Permit ST-9220. <br />Under this permit, liquid wastes entering the LWEL from any possible source of moderate risk or <br />hazardous wastes must be tested for such constituents prior to acceptance. Records, including source of <br />the wastes, amount in gallons and date accepted are kept by Kittitas County Solid Waste. The West <br />Leachate Lagoon currently accepts the transfer station leachate and the Pautzke bait leachate. <br />Pond 4/East Leachate Lagoon operates under WAC 173.350, the Ryegrass landfill closure order. Pond 4 <br />only handles leachate from the closed landfill. <br />7.9.3 Liquid Waste Needs and Opportunities <br />Considering the current population trends and the rate of liquid waste generation, there is a need for <br />additional septage capacity. The amount of liquid waste going into the two septage lagoons currently <br />exceeds the capacity. <br />The City has built a decant facility to handle the liquid from catch basins that is contaminated with <br />petroleum hydrocarbons, as well as street sweeping runoff. <br />7.9.4 Liquid Waste Option and Implementation Actions <br />The following option for improving liquid waste management is recommended and discussed below. <br />7.9.4.1 Expand Septage Capacity <br />Transition Pond 3/West Leachate Lagoon into a septage lagoon and retain Pond 4/East Leachate Lagoon <br />into the County’s only leachate lagoon. <br />7.10 Electronic Waste <br />Electronic waste refers to discarded computers, monitors, printers, fax machines, cell phones, electronic <br />cables, and other electronic products. In 2006, the Washington State Legislature passed Engrossed <br />Substitute Senate Bill 6428, which established the Washington State Electronics Product Recycling Law. <br />The law requires manufacturers of electronic products sold in Washington State to finance and implement <br />electronics collection, transportation, and recycling programs in Washington State. This program is <br />available to households, small governments, small businesses, and charities. Ecology oversees this <br />program. Electronic products that are covered in the legislation include cathode ray tube (CRT) and flat <br />panel computer monitors having a viewable area greater than 4 inches when measured diagonally, <br />desktop computers, laptops, and portable computers. <br />7.10.1 Existing Conditions <br />Implemented in January 2009, E-Cycle Washington provides free recycling of computers, monitors, <br />laptops, and televisions to residents, charitable organizations, small businesses, and small governments. <br />The Washington Materials Management and Financing Authority (WMMFA) sets up and runs the i) .
