Brusca File No. 137-002 BruscaAssociates.com ● P.O. Box 332, Roseville, CA 95661 ● Phone (916) 677-1470 Page 3 March 9, 2018 Murphy Parkway Property Excavation and Materials Management Plan areas are situated on the northwesterly portion of the site (outside of the area of capped solid wastes). Until recently, portions of the site were used for livestock grazing; wire fencing is in place on portions of the site for livestock enclosure purposes. A Vicinity Map showing the location of the property is presented as Plate 1, and a Site Map is presented as Plate 2. The westerly portion of the parcel was subject to past solid waste (primarily glass fragments) handling and disposal (discussed below in Section 3.1). A relatively flat, graded area is situated on the far northwesterly portion of the site; in this area, an engineered soil “cap” was placed atop residual glass wastes in 2013 (see Plate 2). 4.0 BACKGROUND INFORMATION 4.1 Site History The 48-acre subject parcel historically was vacant farmland. In the early 1960s, a large glass manufacturing facility (currently referred to as former Pilkington North America [PNA] facility) was constructed directly northerly of the subject property. The subject 48-acre parcel (identified by APN 198-012-009) was associated with the former PNA facility, and, along with other offsite areas, was used for solid waste handling and waste water disposal related to the PNA facility. Solid wastes comprised largely of waste glass materials were handled within the northwesterly portion of the subject 48-acre site; the vast majority of waste glass materials historically handled and temporarily stored in this area were hauled from the property in the past to offsite disposal locations. Glass manufacturing activities at the former PNA facility were discontinued a few years ago. In recent years, the subject 48-acre parcel generally has been unused, except for some livestock grazing. Treated industrial and domestic waste water, as well as storm water, generated at the former PNA facility northerly of the subject property was disposed at that facility, and also on the subject 48-acre parcel via spray irrigation. The waste water discharge was performed under permit with the Central Valley Regional Water Quality Control Board (CVRWQCB). Because the subject 48-acre property is no longer intended for waste water discharge, the CVRWQCB is currently in the process of removing this area from the waste water discharge permit. 4.2 Summary of Past Investigations and Onsite Work Related to Solid Waste Materials It is indicated that the handling of glass wastes on the subject property ceased in the 1980s. Around 2012, the local oversight agency (the San Joaquin County Environmental Health Department [SJCEHD]) required the placement of a soil cap over the northwesterly portion of the property where a thin layer of residual glass wastes was known to exist. A Soil Cover Workplan was prepared in early 2013, and the capping work was implemented in late 2013.1 The area of the cap is shown on Plate 2. Starting in 2014, a substantial amount of investigation, waste characterization, and waste removal work was implemented on the subject parcel by Advanced GeoEnvironmental, Inc. (AGE) with direction and oversight by the SJCEHD. This work included: 1 Antea Group; “Soil Cover Workplan, Former Cullet Staging Area, Pilkington North America, Inc., 500 East Louise Avenue, Lathrop, California”; May 22, 2013.
