Dear Mr. Ratliff:

We have completed our review of your January 20,1999 and April 23,1999 submittals pertaining to the 28.2 acre Pawlik Production Area on Radioactive Material License No. LO2449, I issued to USX Corporation (USX), Texas Uranium Operations, an in-situ leach uranium recovery licensee. The licensee is requesting that the area be removed from the license, i.e., a ] partial termination of the license. Partial termination of an in-situ leach uranium recovery license requires a demonstration that the groundwater has been adequately restored, all the wells have been closed and plugged according to the appropriate Texas statute, disposal or transfer of radioactive material is documented, and radiation surveys and confirmatory soil samples indicate that the site meets unrestricted release requirements. In addition, the partial termination requires a demonstration that release of the portion of the site will not negatively impact the remainder of the site to be closed at a later date. The information you have submitted indicates that the groundwater has been restored by the licensee to the satisfaction of the Texas Natural Resource Conservation Commission (TNRCC). I All the wells have been plugged and abandoned by the licensee as authorized by TNRCC. Based on the Texas Department of Health's (TDH) review of the partiallicense termination, you reported that proper disposition of radioactive materials took place at the site and there has been no on-site disposal of radhactive materials; therefore, there is no need to transfer ownership of land to the State or the Federal Government. TDH has reviewed the results of radiation surveys and soil samples submitted by the licensee and performed confirmatory surveys for the subject site. Post-cleanup surveys conducted by TDH indicate that the site has been decontaminated to a radiation level that meets the State criteria. According to the TDH report, the analysis of soil samples indicates that average i radium 226 and uranium concentrations were below release criteria of 5 pCi/g and 30 pCl/g, respectively. TDH has also evaluated the impact of release of the subject site and determined that the release will not impact the remainder of the site. The statements made in your ( submittals indicate that the TDH has adequately determined that all license obligations have [ been met by the licensee. The most recent review of the Texas Agreement State Program, conducted under the Integrated Materials Performance Evaluation Program (IMPEP) in June 1997, indicates that the Texas program is adequate to protect public health and safety, and compatible with NRC's program. This finding is consistent with the previous Texas program evaluations. Based on our $00b Wb a~xqQ fh Nd6Y7 9905280159 990513 PDR STPRG ESGTX / PDR

Dear Mr. Lohaus:

Jtem i The Texas Department of Ilealth (TDil) has received a request from USX Corporation (USkiT ) Texas Uranium Operations, dated December 8.1997 (Enclosure 1), pertaining to the 28.2 acre Pawlik Production Area on Radioactive Material License No. LO2449. The Licensee is requesting i that the area be removed from the license. The license authorized in situ leach mining in the area. This area was operated from 1977 to 1987, when production operations were ceased and reclamation efforts were commenced. From 1987 until 1996 groundwater restoration was performed along with limited surface reclamation. The Texas Natural Resource Conservation Commission authorized ceasing { groundwater restoration and final plugging of all wells in July 1996 (Enclosure 2). Following i plugging of all wells, full scale surface reclamation and decommissioning began. During surface reclamation and decommissioning all material and equipment was surveyed for radioactive contamination. Any material and/or equipment which was contaminated was disposed of by utilizing one of the following methods: i transfer to another licensed mine site: decontamination and release for unrestricted use: or disposal at a licensed byproduct disposal facility. 6--6 // Proper disposal of all material and/or equipment was documented by the licensee. Direct surveys, by the licensee, to connrm the effectiveness of reclamation and decommissioning activities of land were performed by denning ten meter by ten meter squares in a grid pattern q*3 across the production area and taking five readings in each square with a micro R meter. The licensee subsequently requested removal of the production area from its license. ~ Adf h& PDR BTPRQ E90TK llf' PDR j

Paul Lohaus January 20,1999 Page 2 Reclamation and decommissioning activities were completed at the site in 1997.___] In December,1997 TDil personnel performed a confirmation survey of the production area. The surveys were performed using one by-one sodium i< iide probes and Ludlum 14C survey meters. The purpose of the survey was to allow the Licensec to release the production area for unres Two times background was used as an allowabic limit (FDil Regulatory Guide 5.10 use. Guidelines for Conducting Close Out Surveys of Open Lands and Requesting Release Unrestricted Use. The survey was performed by walking 10 meters apart movmg across production area. ) Background readings were 1500 cpm, 2000 cpm instruments used. Sixteen areas were identified which exceeded two times background. These areas were cleane up by the Licensee and resurveyed by TDit personnel. Two areas still exceeded two times background after the cleanu). retrieved from live areas ay TDil personnel. including the two which exceeded tw background (TDil Regulatory Guide 5.10, Guidelines for Conducting Close Out Surveys Lands and Requesting Release for Unrestricted Use). Soil sample results were within the regulatory limits for radium-226 and natural uranium soil concentrations of 5 pCi/gm and 30 pCi/gm, respectively, except for two soil samples which exceeded these limits. In April,1998. TDrl personnel returned to the Pawlik Production Area to survey and take soil samples after the Licensee had cleaned the areas that had exceeded release limits. Soil sa results were within the regulatory limits for radium-226 and natural uranium soil concentrations of 5 pCi/gm and 30 pCi/gm, respectively. On-site disposal of solid radioactive material or byproduct material was not authorized at this facility. Thus, there is no land to be transferred to the State of Texas or the Federal Government. As a result of these findings, we are proposing to remove the Pawlik Production Area from this license (Enclosure 3. All data supporting our proposal are kept on file and is available at TDil should it be necessar)y for reference at a future date. Please advis Commission wishes additional material or information in order to make a determination rega concurrence with our proposal that the production area be removed from this license, if additional information is required, please contact Mr. Eugene Forrer of my staff at (512) 834-6688, ext. 2208. This lett:r is a resubmittal of a request sent in September of 1998. As maintaining this site places an undue economic burden and hardship on the licensee, we request expeditious processing of this request. Sincerely, l tJ j Richard A. Ratliff, .E.'

PATTERN AREA The preliminary pR/Hr soil surveys were conducted from June 16,1996 to July 5,1996. The pattom area was marked in 10 meter grids with a 30 meter perimeter area surrounding the actual pattoms. The grids were surveyed using Ludlum Model 19 micro R meters such that at least five readings were recorded within each 100 sq. meter grid. Areas that had readings above twice background were flagged and delineated for the extent of contamination. Contaminated material from the initial survey was shipped to Rio Grande Resources' waste site at Panna Maria, Texas. Follow-up surveys were conducted in the summer of gg# 1997 prior to a request to have the TDH perform a confirmation survey of the pattom area in a memo to Mr. Brad Caskey on December 8,1997. The confirmation survey was completed during the third week of December 1997. Sixteen areas showed readings more than twice background. Ten of these areas were ( small enough to be remediated during the confirmation survey..The pR/Hr readings for five amas remained questionable. The TDH and TUO split samples at those five locations and took one sample from an area designated as a background reading. The results of the split sampling and other soil samples taken by TUO personnel are shown in Table 1. Also attached with this report is a map showing the final pR/Hr survey readings. PAWUK PIPEUNES Two sixteen inch pipelines were used to transfer production solution and barren solution j between the Pawlik pattom area and Satellite IV at the Boots / Brown mine. Survey data taken along the transfer pipelines are shown in Tables 2 and 3. M:rathon oil company uSs u.S. Diversified Group - TIx s Oil & Gas corp.

Mr. Gene Forrer i Page 2. September 22,1998 SPILL REVIEW Review of the spill files showed that seven spills had been reported since 1981. These spills are listed in Table 5. Most of the spills were within the pattom area. Three of the spills were along the Pawlik pipelines discussed in the previous sechon Survey data and soil samples taken from the spill area adjacent to the pipeline are shown in Table 4.

SUMMARY

Maps included with this report are a Permit location map and pattom area survey map. Tables included are pattom soil samples, pipeline surveys, spill surveys and soil - samples, and a list of the spills. The surface area of Permit 02368 PAA 011 has been remediated and documented. TUO is requesting that the surface area at the Pawlik mine be released for unrestricted use. If you have any questions or need additional information please call me at 512-449 2515 or fax at 512-566 2442. Sincerely, i M M.Q Charles N. Wentz Manager-Operations

  1. lOfTROL RADI Re:- Survey Release Requests, License No. RW2449

Dear Mr. Caskey:

The purpose of this letter is to request confirmation release surveys on three additional projects. Also, we would like verification of the remediation completed at the Pawlik mine. These projects are discussed in the following paragraphs. 1. Pawlik l#!ne During confirmation surveying of Pawlik mine pattom area (TNRCC Permit No. 02368) several soil samples were taken by personnel from the TDH and TUO. Three sets of surface soil samples showed Re 226 values higher than the release limit of 5 piCilg above background. A copy of the letter I ] sent Mr. Oscar Lessard regarding the final results on two of the remediated areas is attenhed with this letter. The third area, TDH Sample No. 8 (TUO location 550 E/W by 230 NIS), showed a total Rs 226 of 6.9 pCilg in the TDH sample and 4.2 pCilg in the TUO sample. We remediated this area also, as only one spot in the five-spot sample area had an elevated pR/Hr reading. The third area was also re-sampled and the results should be available in about one week. We are requesting a final survey of the three remediated areas. 2. Cono ete Five satellite areas at the Clay West and Bums Ranch facilities have concrete pad material ready to be surveyed. The concrete slabs at four of these areas were cored and analyzed for uranium and radium before they were broken up. Summary sheets of the core analyses are attached with this letter. The concrete from the fifth area, Bums Ranch Satellite 1, did not originate from a i process area and was not cored. Micro R readings on all five areas are also attached with this letter. 3. Bums Ranch Central Plant Process Ponds These small process ponds (approx. 70 ft X 70 ft) are located near the former area of the Bums Ranch Central Plant. All sludge, liner material, and sub-soil have been remediated. Documentation of the soil analysis and micro R surveys is attached with this letter. Mar thon Oil Cornpany USS U.S. Diversified Group Tom:s oil & Gas Corp. ~

o Mr. Brad Caskey Page 2. March 19,1998 4. Boots / Brown Mine The pattern areas at the Boots / Brown mine (THRCC Permit No. 02154) have been surveyed, remediated, and re-surveyed. A map showing the surveys is attached with this letter. The readings in red, 20 to 24 pR/Hr are being sampled as fiv6 spots. Since the TDH will rrcst likely take soil samples also, we would like to proceed with the close-out survey as soon as it can be scheduled. These projects are listed in the preferred sequence of confirmation. If you have any questions, or need additional information, please let me know. Sincerely, % w. 4 Charles N.

SUBJECT:

RELEASE FOR UNRESTRICTED USE PAWLIK PATTERN USX CORPORATION, GEORGE WEST, TX DATE: JUNE 5,1998 PAWLIK PATTERN: On December 15-17,1997, Bureau of Radiation Control employees, Brad Caskey, Oscar lessard, and Gene Forrer, perfbrmed a survey of the Pawlik Pattern at USX Corporation in George West, Texas. The surveys were performed using one-by-one sodium iodide probes and Ludlum 14C survey meters. The purpose of the survey was to allow the Licensee to release the 28.2 acres for unrestricted use. Two times background was used as an allowable limit (Regulatory Guide 5.10, Guidelines for Conducting Close Out Surveys of Open Lands and Requesting Release for Unrestricted Use). The survey was performed by walking 10 meters apart moving across the wellfield pattern. Background readings ranged from 1500 cpm for Oscar Lessard,2000 cpm for Gene Forrer and 2400 cpm for Brad Caskey. Maps and survey results are attached (see Attachment A-1). Sixteen areas were identified which exceeded two times background. These areas were cleaned up by the Licensee and resurveyed.

Soil samples were retrieved from five areas (Sample #'s 3, 6, 8,16, and Background) after the Licensee cleaned them up. Soil samples collected were representative of the 100 square meter by 15 centimeter in depth sampling method. Five each 15 centimeter deep core samples were collected in each 100 square meter area. The five core samples from each 100 square meter area were then dried and mixed together. A representative sample from the mixture was used for analysis. Results of the five soil samples for radium-226 and natural uranium concentrations in picoeuries per gram (pCi/gm) are as follows: Ramnle # Radium-226 (pCi/cm) Nat Uranium (pCi/am) 3 5.4 (4.4) 2.3 6 5.4 (4.4) 2.8 8 6.9 (5.9)** 6.1 16 13 (12)** < 2.0

Soil sample # 16 was taken from an area of approximately 200 square meters where the radiation levels were 6000 cpm over the entire area.

On April 28-30,1998, Brad Caskey, Rick Munoz, Mike Dunn, and Oscar lessard returned to the Pawlik Pattern to resurvey and retake soil samples after the Licensee recleaned the land areas identified as sample #8 and sample #16. l

Dear Mr. Hseuh:

This letter is regarding the addi

  • nal information you requested, during a telephone conversation on April 22,1999, l

I concerning the areas review to determine that there would be no negative impact, on the remainder of the licensed l areas, by releasing the f wing from the associated license: USX license LO2449.1Pawlikj& Sparkman production areas; I RGR license L02402; and IEC license LO2538, Pawnee production area. Agency personnel have determined that the release for unrestricted use and removal of these areas will not negatively impact the remainder of the sites associated with the licenses, which will be released for unrestricted use and removed from the license at a later date, based on the following; with the exception of the RGR site all sites are not contiguous with any other site associated with licensed activities: removal of the sites from their associated licenses will not in any way prevent or hinder the licernees ability to complete decommissioning of the remainder of the licensed areas; . in the case of the RGR site, removal of the areas outside the disposal cell is a precursor to turn over of the disposal cell i site to the State of Texas or the DOE; and all applicable state and federal requirements for release for unrestricted use have been met. l As maintaining this site places an undue economic burden and hardship on the licensee we request expeditious processing of this request. If you have any questions, please call me at (512) 834-6688 extension 2208. j i Sincerely, -)// \\ Eugene (Gene) Forrer Chief Uranium Licensing Project Divis} yon of Licensing.
