Title: ERRATA SHEET for Post-Closure Inspection Report for Corrective Action Unit 407: Roller Coaster RadSafe Area Tonopah Test Range, Nevada, Calendar year 2001

Abstract

The fifth sentence of the first paragraph on Page 1 of the Post Closure Inspection Report for Corrective Action Unit 407: Roller Coaster RadSafe Area, Tonopah Test Range, Nevada erroneously states that Revision 1 of the CR was issued in December of 2001 and was approved by NDEP on January 7, 2002. The sentence should state that Revision 1 of the CR was issued in December of 2001 and was approved by NDEP on February 22, 2002.

  • Post-closure monitoring requirements for the Roller Coaster RadSafe Area (Corrective Action Unit [CAU] 407) (Figure 1) are described in Closure Report for Corrective Action Unit 407, Roller Coaster RadSafe Area, Tonopah Test Range, Nevada, report number DOEN-694, October 2001. The Closure Report (CR) was submitted to the Nevada Division of Environmental Protection (NDEP) on April 24,2001. No issues with the post-closure monitoring plan, Section 5 .O, were raised. However, other concerns raised by stakeholders required that the CR be revised. Revision 1 of CR was issued in December of 2001 and was approved by NDEP on January 7,2002. Section 5.2more » of the NDEP-approved CR calls for site inspections to be conducted within the first six months following completion of cover construction. Following the first six months, site inspection are to be conducted twice yearly for the next two years. This report provides the results of the six month post-construction site inspection. As stated in Section 5.2 of the CR, Post-closure site inspections at CAU 407 consists of the following: (1) Visual site inspections done twice a year to evaluate the condition of the cover and plant development. (2) Verification that the site is secure and condition of the fence and posted warning signs. (3) Notice of any subsidence, erosion, unauthorized excavation, etc., deficiencies that may compromise the integrity of the unit. (4) Remedy of any deficiencies within 90 days of discovery. (5) Preparation and submittal of an annual report. To meet the fiscal year 2002 post-closure inspection schedule, the first post-closure site inspection was conducted on November 6,2001. The site inspection was conducted after completion of the revegetation activities (October 24,2000) and submittal of revision 0 of the CR (October 31,2001). All site inspections were conducted in accordance with the Post-Closure Inspection requirements stated in revision 0 of the CR. This report includes copies of inspection checklist, photographs, recommendations, and conclusions. The Post-Closure Inspection Checklist is found in Attachment A, a copy of the field notes is found in Attachment By and copies of the inspection photographs are found in Attachment C.« less

  • This closure report (CR) provides documentation for the closure of the Roller Coaster RADSAFE Area (RCRSA) Corrective Action Unit (CAU) 407 identified in the Federal Facility Agreement and Consent Order (FFACO) (Nevada Division of Environmental Protection [NDEP] et al., 1996). CAU 407 is located at the Tonopah Test Range (TTR), Nevada. The TTR is approximately 225 kilometers (km) (140 miles [mi]) northwest of Las Vegas, Nevada (Figure 1). The RCRSA is located on the northeast comer of the intersection of Main Road and Browne's Lake Road, which is approximately 8 km (5 mi) south of Area 3 (Figure 1). Themore » RCRSA was used during May and June of 1963 to decontaminate vehicles, equipment, and personnel from the Double Tracks and Clean Slate tests. Investigation of the RCRSA was conducted from June through November of 1998. A Corrective Action Decision Document (CADD) (U.S. Department of Energy, Nevada Operations Office [DOEN], 1999) was approved in October of 1999. The purpose of this CR is to: Document the closure activities as proposed in the Corrective Action Plan (CAP) (DOEM, 2000). Obtain a Notice of Completion from the NDEP. Recommend the movement of CAU 407 from Appendix III to Appendix IV of the FFACO. The following is the scope of the closure actions implemented for CAU 407: Removal and disposal of surface soils which were over three times background for the area. Soils identified for removal were disposed of at the Area 5 Radioactive Waste Management Site (RWMS) at the Nevada Test Site (NTS). Excavated areas were backfilled with clean borrow soil located near the site. A soil cover was constructed over the waste disposal pit area, where subsurface constituents of concern remain. The site was fenced and posted as an ''Underground Radioactive Material'' area.« less
  • Corrective Action Unit (CAU) 424, the Area 3 Landfill Complexes at Tonopah Test Range, consists of eight Corrective Action Sites (CASs), seven of which are landfill cells that were closed previously by capping. (The eighth CAS, A3-7, was not used as a landfill site and was closed without taking any corrective action.) Figure 1 shows the general location of the landfill cells. Figure 2 shows in more detail the location of the eight landfill cells. CAU 424 closure activities included removing small volumes of soil containing petroleum hydrocarbons, repairing cell covers that were cracked or had subsided, and installing above-grademore » and at-grade monuments marking the comers of the landfill cells. Post-closure monitoring requirements for CAU 424 are detailed in Section 5.0, Post-Closure Inspection Plan, contained in the Closure Report for Corrective Action Unit 424: Area 3 Landfill Complexes, Tonopah Test Range, Nevada, report number DOE/NV--283, July 1999. The Closure Report (CR) was approved by the Nevada Division of Environmental Protection (NDEP) in July 1999. The CR includes compaction and permeability results of soils that cap the seven landfill cells. As stated in Section 5.0 of the NDEP-approved CR, post-closure monitoring at CAU 424 consists of the following: (1) Site inspections conducted twice a year to evaluate the condition of the unit. (2) Verification that landfill markers and warning signs are in-place, intact, and readable. (3) Notice of any subsidence, erosion, unauthorized use, or deficiencies that may compromise the integrity of the landfill covers. (4) Remedy of any deficiencies within 90 days of discovery. (5) Preparation and submittal of an annual report. Site inspections were conducted on May 16, 2001, and November 6, 2001. The inspections were preformed after the NDEP approval of the CR. This report includes copies of the inspection checklist, photographs, recommendations, and conclusions. The Post-Closure Inspection Checklists are found in Attachment A, a copy of the field notes is found in Attachment B, and copies of the inspection photographs are found in Attachment C.« less
