' HISTORIC FUELING AREA, LIMITED SOIL SAMPLING <br />BMG RESOURCES' SAN LUIS FACILITY <br />' SAN LUIS, COLORADO <br />October 22, 2002 <br />Terracon Project Number: 46027059 <br />1.0 PROJECT BACKGROUND AND SITE DESCRIPTION <br />Terracon has completed the limited soil sampling in the area of BMG Resources' historic <br />' fuel and lubricant storage and dispensing operation. The San Luis facility is located <br />approximately 3.5 miles northeast of the town of San Luis, Colorado. The fueling area (site) <br />was located west of the vehicle ready-line and north of the office/laboratory buildings (see <br />Figure 1 Site Diagram in Appendix A and the 1999 USGS Aerial Photograph in Appendix B). <br />The site is approximately 80 feet by 110 feet and is lined with a synthetic material. The <br />' Liner is anchored by a berm at the perimeter of the site. The liner is covered by <br />approximately 24 inches to 30 inches of fill material. Based on information provided by Bill <br />Lyle of BMG Resources, petroleum hydrocarbon products used at the site included <br />' gasoline, diesel fuel, hydraulic fluid, and oil. All petroleum products were stored in and <br />dispensed from aboveground storage tanks (ASTs) or 55-gallon drums that were located <br />within the bermed and lined site. All storage and fueling equipment have been removed <br />' from the site. Terracon did observe what appeared to be the electrical connection for the <br />historic fuel pumps (see Figure 1 in Appendix A). <br />' 2.0 SCOPE OF SERVICES <br />' BMG Resources retained Terracon to provide environmental services in an attempt to <br />identify obvious releases of petroleum hydrocarbon materials at the site. At the direction of <br />BMG Resources, Terracon performed the following tasks: <br />• Reconnaissance of the site and immediately surrounding area; <br />• Excavation and observation of backhoe test pits advanced in the central portion of <br />the site; <br />• Collection of soil samples for laboratory analysis to detect benzene, toluene, <br />ethylbenzene and xylenes (BTEX) and to detect total recoverable petroleum <br />hydrocarbons (TRPH); <br />• Backfilling with the material removed from each excavation; and; <br />• Preparation of this report, summarizing the analytical results. <br />1 <br />
