' • Volatile organic compounds (VOCs) by EPA Method 8260 <br />• Total recoverable petroleum hydrocarbons (TRPH) by EPA Method 418.1 <br />' Diesel range petroleum hydrocarbons by EPA Method 8015 <br />• Oil and grease by EPA Method 413.1. <br />The results of the preliminary analytical tests are summarized in Table 1. This table presents <br />the sample names, descriptions, and analytical test results for the samples collected on <br />November 12. Sample locations are illustrated in Figure 2. The complete laboratory test report <br />is presented in Appendix C of this SAP. The test results presented in Table 1 are summarized, <br />as follows: <br />• While 2,4-D was present in this sample, the weed killer's concentration was below regulatory <br />limits that would require treating the pile as a hazardous waste. The sample from the minus <br />%Z inch road base pile contained 2,4-D (1.1 mg/kg), TRPH (240 mg/kg), and oil and grease <br />(30 mg/kg). This sample contained no VOCs in concentrations above the method detection <br />limits. Test results for this sample also show that virtually all the TRPH detected in the <br />sample consisted of diesel-range organic compounds. This result confirms that the released <br />chemical was the Repco Kill IIT" product, which includes 90 percent or more diesel. Another <br />chlorinated weed killer, Dicamba, was also detected, but at levels below the permissible <br />quantitation limit (PQL). <br />• The sample from the minus'/. inch road base and washed sand piles contained no <br />contaminants that would indicate they were impacted by the released chemicals. Dicamba <br />was detected, but at levels below the PQL. <br />• Wipe samples from drums stored in the wash plant settling basin contained elevated <br />concentrations of 2,4-D weed killer. The weed killer concentrations ranged from 20 mg/kg to <br />80 mg/kg in the wipe samples. The weed killer Dicamba was detected in these samples but <br />at levels below the PQL. <br />• The sample of bag house dust (MP-BHD) contained 12.0 mg/kg of 2,4-D, which is above <br />RCRA's land disposal restriction level. Diacamba was detected but at concentrations below <br />the PQL. <br />' B&B Excavating, Inc., Edwards, Colorado December 17, 1998 <br />Montgomery Pit Facility 39210-003-034 <br />Draft Sampling and Analysis Plan 10 DAMES 8 MOORE <br />
