EnviroLogic Resources, Inc.TECHNICAL SPECIFICATIONS FOR DRILLING OPERATIONSRemedial Investigation/Feasibility StudyAstoria Area-Wide Petroleum SiteAstoria, Oregon1.0 INTRODUCTIONThese specifications describe the methods and procedures required for the drilling and sampling of soilborings and constructing monitoring wells. The soil borings will be advanced using GeoProbe TM directpush, or another hydraulically-powered drilling rig. The hollow-stem auger drilling method may be usedto drill and install monitoring wells. The proposed boring locations are located at the Astoria Area-Wide Petroleum Site in Astoria, Oregon, as shown on Figure 1. The maximum estimated depth of thesoil borings will be approximately 20 feet. Final design of monitoring wells and selection of theirlocations will be completed after the initial soil characterization phase.Soil borings will be drilled on behalf of Potentially Responsible Parties (PRPs) involved in conducting aremedial investigation at the Astoria Area-Wide site. Each PRP has retained a consultant to manage thework, as shown below:PRPChevron TexacoDelphia OilHarris/Van WestMcCall OilNiemi OilPort of AstoriaQwestShell OilCONSULTANTPNG Environmental, Inc.Maul Foster & Alongi, In.Kleinfelder, Inc.Anchor Environmental, LLCGeoEngineers, Inc.EnviroLogic Resources, Inc.Tetra Tech EM, Inc.Hart Crowser, Inc.1
EnviroLogic Resources, Inc.These consultants will be responsible for oversight of soil boring drilling operations conducted at theirPRP facility. EnviroLogic Resources will provide overall site coordination and oversight on installationof monitoring wells.1.1 UTILITY LOCATINGNo drilling shall take place without approval of the consultant representing the PRP facility to beinvestigated. The Utility Notification Center at (800)332-2344 will be notified by the consultant tocoordinate clearance from utility companies that may have lines in the area. A locating survey will beconducted by a private locating company contracted by the consultant to identify subsurface features.The Contractor shall carefully probe to a depth of 3 feet to avoid damaging undocumented andunidentified utilities. Approval to begin normal drilling operations will be provided by the onsitesupervisor for the consultant.1.2 ACCESSAll drilling locations are in easily accessible areas of the site. Most of the area is paved or has a gravelroad base. Some unpaved areas are composed of sandy materials. Care should be taken whenaccessing areas that could pose traction problems. The presence or absence of overhead power linesshall be noted before rigging up. The consultant will arrange for ingress, egress, and rights-of-way to alldrilling locations.1.3 AVAILABILITY OF WATER AND POWERThe Contractor will provide all electrical power needed for drilling operations and decontamination ofequipment. We believe water is available onsite. The Contractor shall be responsible for all fluidsproduced during drilling operations except samples collected for analytical purposes. Handling ofinvestigation-derived wastes (IDW) is discussed in Section 8.0.2
