"In 2020, all job groups have an increased TEDE in comparison to 2018 and 2019 as a result of an increase in radon daughters. This was attributed to tanks in the PWT [Pond Water Treatment] area, which has had water added to reduce radon and radon daughter levels in September - October 2020. Review of the radon daughter levels in Pond Water Treatment and the Plant average indicate that this may not have provided the reduction anticipated. It is recommended that radon daughter level trends be continually reviewed over the next year to confirm that the levels have returned to the expected range and to provide additional remedial actions if it has not. However, since very little time is spent in the PWT area by workers, the dose increase as a result of the increased radon daughters in the area is likely an overestimate, and actual doses are probably more comparable to previous years.
Overall, the average TEDE increased from 2018 and 2019, from 0.067 rem [0.67 mSv] and 0.083 rem [0.83 mSv] respectively, to 0.135 rem [1.35 mSv] for 2020." [emphasis added]

Determination of contaminant levels and remediation efficacy in groundwater at a former in situ recovery uranium mine, by Borch T , Roche N, Johnson TE, in: Journal of Environmental Monitoring Vol. 14, No. 7 (April 2012), p. 1814-1823
The study is based on the data published by Power Resources Inc. in "Report entitled 'A-Wellfield Ground Water Stability Report' submitted to the WDEQ in Correspondence dated March 31, 2000", available as Attachment C in Adams Acc. No. ML040300369 .
"By letter dated June 26, 2009, Cameco submitted its Mine Unit B Ground Water Restoration Report for NRC approval. The report contained supporting data and related historical documentation leading to approval of the restoration by the Wyoming Department of Environmental Quality (WDEQ) between 2004 and 2008.> Download Public Meeting Summary
During the acceptance review, staff observed that one monitor well appeared to remain on excursion status at the completion of groundwater restoration. Additionally, the staff identified that there appeared to be pumping activities at several perimeter and overlying monitor wells during the stability monitoring period that were not fully described in the report. By letter dated September 29, 2009, the staff did not accept it for a detailed technical review. Since that time, Cameco has re-evaluated the groundwater restoration data for Mine Unit B and has decided to pursue a request for alternate concentration limits (ACLs) in this mine unit to accompany the revised report."

a. Wellfield C was in production for approximately ten years. The approved Mine Plan states, "Once a wellfield is installed it takes approximately one to three years to recover the leachable uranium from a production area." Extending the production time period has become a routine practice and is not in compliance with the approved permit or the requirement for concurrent reclamation.
b. In addition to the production phase, Wellfield C has now been in restoration for ten years. The 2007 Annual Report states that the ground water quality is similar to "end of mining" wellfield conditions. The permit states that restoration and stability are estimated to take approximately five years. This restoration delay is not in compliance with the approved permit or the requirement for concurrent reclamation.
c. Wellfield E has removed 100% of the leachable reserves, and in recent years wellfield production has slowed to maintenance levels. This rate of production delays completion of mining and restoration of this wellfield unit. This is not in compliance with the approved permit, and is a violation of Chapter 2, Section 2(b)(ii) which requires coordination of the Mine and Reclamation Plans to facilitate orderly development and reclamation.
d. The timetable listing the schedule of mining-related activities in the permit (Figure A, page OP-3A) and the timetable provided in the 2007 annual report both indicate that PRI is not in compliance with their restoration schedules for Wellfields C, D, and E. The schedule shows that Wellfield C should be decommissioning instead of in restoration, and that Wellfields D and E should be in restoration instead of production.

"The Land Quality Division has reviewed the fate and transport modeling conducted by PRI and concurs that the modeling indicates natural attenuation will prevent the groundwater within the wellfield from endangering (with an exceedance of EPA's MCL's) the class of use of the adjacent groundwater. [...]"DEQ LQD determined
"[...] that although the groundwater has not been returned to baseline conditions, the groundwater quality is consistent with the pre-discharge use suitability of the water (Class IV(A) suitable for industry). [...]By letter dated Jan. 15, 2004, PRI requested NRC to concur with the Wyoming DEQ determinations.
However, because the groundwater conditions differ from the background water quality and because of the reliance on natural attenuation for the protection of adjacent groundwater monitoring will be required to substantiate the model predictions."
The A-Wellfield 20-Sand Production Zone was mined using the In Situ Leach (ISL) mining method from January 1988 until July 1991. PRI then completed groundwater restoration from July 1991 to October 1998.

On March 5, 2008, Cogema Mining Inc. submitted the Wellfield restoration report for Mine Units 2-6 of its Christensen Ranch uranium in-situ leach mine in Wyoming.
Constituents that exceeded Target Restoration Values (TRVs) and either WDEQ or EPA standards in at least one Mine Unit were iron (Fe), manganese (Mn), selenium (Se), total dissolved solids (TDS), uranium (U) and radium-226 (Ra-226). The uranium values are listed below.
According to Cogema, groundwater within the production zone has been restored to the pre-mining class of use and the groundwater restoration meets the requirements for unconditional restoration approval by WDEQ and NRC.

"COGEMA has not restored ground water to primary, or background, standards. However, because of the restoration efforts made by COGEMA and the use of best practicable technology, the NRC considers the WDEQ secondary restoration standards and the NRC premining use category as the applicable restoration standards in lieu of the primary goal of restoration in LC 10.16. The WDEQ class-of-use standards (NRC premining use standards) have been met and approved by WDEQ, and the NRC concurs with this approval. Therefore, the NRC concludes that ground-water restoration to the premining use category in LC 10.16 is complete in COGEMA Irigaray Mine production units 1 through 9 and that wellfield decommissioning can commence."
"SUMMARY: [...] Today's approval of this new aquifer exemption will allow COGEMA to use the newly permitted Class I injection wells to inject ground water restoration waste fluids from the Wasatch Formation into the Lance Formation. As a result of this increased disposal capacity, COGEMA will be able to restore the Wasatch ground water more quickly and pump and treat less ground water. The rate of pumping out of the Wasatch will prevent any negative impact to the adjacent portions of this USDW. [...]"

An examination of 32 permits from closed South Texas in-situ leach mines showed that in each case, companies were permitted to leave behind minerals such as uranium, molybdenum and selenium at higher levels in groundwater than were listed in the original permit. In some cases, companies were able to meet the restoration target for one mineral but reported 10- and 20-fold increases in others. Older mines tended to require more drastic permit amendments than mines started later. (Corpus Christi Caller-Times, Nov. 5, 2006)

"Item 4.
Docket No. 95-0877-UIC. Consideration of an application by CHEVRON U.S.A., INC., DBA CHEVRON RESOURCES COMPANY for an amendment to the production area authorization for Production Area No. 1 under existing Permit No. UR02051-011 at its Palangana in situ uranium mine site. The proposed amendment would revise restoration values for conductivity, ammonia, molybdenum, radium-226 and alkalinity. The proposed values will not change the use category of the water. Prior to mining, the water in the production area was used for livestock. Chevron Resources Company has met the following criteria set forth in 30 TAC 331.107(f)(2) for an amendment to restoration table values: a) reasonable efforts have been taken by the company to restore the aquifer; b) the formation water in the aquifer is suitable for any use to which it was suitable prior to mining; and c) further restoration efforts would consume energy, water, or other natural resources of the state without providing a corresponding benefit to the state. The Palangana site is approximately 5.4 miles north of Benavides, and .6 mile west of Farm Road 3196, in Duval County. Texas. The production zone is in the Goliad Formation at a depth of 230 to 390 feet below land surface. (Lisa Roberts)Approved, PR/RM"

"Although NRC is not the regulator of this site, the NRC staff is aware of the State of Texas (the State) regulatory activities for the former International Energy Corporation in situ uranium recovery operations that includes both the Lamprecht and Zamzow well field locations. We understand the State has revoked the license due to the licensee's lack of adequate action to reclaim the surface contamination at the properties to unrestricted use levels. The State regulators have been pursuing use of the financial surety funds to complete the reclamation of the properties. This activity is currently in litigation and will likely go to trial later this year. Our understanding is that upon a decision by the court on the use of the surety funds, it will take one to two years to complete the surface reclamation of these properties."

Item 21.Excerpt from Uranium Institute News Briefing 97.28:
"INTERCONTINENTAL ENERGY CORPORATION (IEC) for an amendment to Production Area Authorization No. 1 (Permit No. UR02108-011) at the Zamzow Mine Site. The proposed amendment would change restoration values for sodium, bicarbonate, pH, alkalinity, arsenic, ammonia, uranium, molybdenum, and radium-226. Prior to mining, the water in the production area was used for livestock. The water will remain suitable for this use with the proposed values. The Zamzow Project is located in Live Oak County, Texas, approximately eight miles east of the Three Rivers and 65 miles northwest of Corpus Christi. The production zone is in the Oakville sand at a depth of 35 to 225 feet or approximately 65 to 130 feet below mean sea level."SIGNED JUNE 27, 1997
"US: Cima Energy's groundwater restoration activities at former ISL uranium mines in South Texas were concluded when the Texas Natural Resources conservation Commission approved the completion of groundwater restoration at the Zamzow site. The three Cima mines involved - Zamzow, Lamprecht and Pawnee - were the last three ISL operations in the US to use ammonium bicarbonate, and according to Cima president Wallace Mays, the cleanup is probably the largest groundwater restoration project ever undertaken.
