- Some Mine Wastes Are Similar To Waste Produced From UR Milling
Operations;
- While Mine Wastes Are Currently Regulated By The States, Some Have
Suggested Regulating Radioactive Mine Waste In A Similar Fashion To
Uranium Mill Tailings;
- UR, LLRW And NORM Regulatory Proceedings And Requirements Provide A
Working, Changing, Real-life Laboratory To Evaluate Potential Future
Regulatory Developments.
|
|
3
|
- Four Entities That Impact UR Recovery, LLRW, and NORM Regulation Include
- NRC
- EPA
- DOE
- Interstate Compacts
- We Address Each Below.
|
|
4
|
- Uranium Recovery (UR) Operations Regulatory Program;
- Low Level Radioactive Waste (LLRW) Regulatory Program.
|
|
5
|
- A. The UR Operations Regulatory
Program
- 1. NMA Issued White Paper On UR Regulation In 19981--
Examined Key Elements of NRC’s Regulatory Program For UR, And
Proposed Reforms.
- Goal Of White Paper: Establish A Rational, Coordinated Framework For
Regulation Of UR Activities.
|
|
6
|
- NMA’s White Paper Addressed The Following Issues:
- Concurrent State/NRC Jurisdiction Over Non-Radiological Components of
Byproduct Material;
- NRC Regulation of ISL Activities (not discussed);
- Direct Disposal of Non-11e.(2) Byproduct Material in UR Tailings
Disposal Facilities;
- Use of Alternate Feeds at Licensed UR Mills.
|
|
7
|
- Concurrent Jurisdiction Issue: Do Non-Agreement States Exercise
Concurrent Jurisdiction Over Non-Radiological Aspects of 11e.(2)
Byproduct Material?
- 1980 NRC Staff Position:2 “Yes”
- Position Developed Just After Passage of UMTRCA, When Expansive New
Statutory Authority Not Well Understood and Regulatory Program in
Infancy.
|
|
8
|
- Practical Implications of Concurrent Jurisdiction:
- Dual Federal/State Regulation -- Resulting in Sub-Optimized Disposal
Requirements;
- Delays in Site Closure As Licensees Attempt to Satisfy Different,
Sometimes Inconsistent Sets of Requirements;
- Reluctance of DOE to Assume Custody Following Site Closure. 3
|
|
9
|
- White Paper Arguments:
- UMTRCA Establishes a Pervasive Federal Scheme of Regulation Over Both
Radiological and for the First Time Non-Radiological Aspects of 11e.(2)
Byproduct Material;
- Concurrent Jurisdiction Conflicts With The Statute And Frustrates
Congress’ Purpose Of Ensuring Timely Disposition of Tailings Under
Uniform National Standards.
|
|
10
|
- In August 2000, NRC Adopted the Position Advocated in NMA’s White Paper,
Voting to Assert Exclusive Jurisdiction Over Both Radiological and Non-Radiological
Aspects of 11e.(2) Byproduct Material.4
|
|
11
|
- Direct Disposal of Non-11e.(2) Byproduct Material In Uranium Mill
Tailings Impoundments:
- Sound Policy Due To Limited Capacity for High Volume, Low Activity
Wastes;
- Current NRC Policy Creates Numerous Hurdles Licensees Must Overcome,
Making it Nearly Impossible to Dispose of Non-11e.(2) Material in
Tailings Impoundments. 5
|
|
12
|
- NMA White Paper Proposed Several
Modifications to NRC’s Non-11e.(2) Disposal Policy, To Facilitate Use of
Tailings Impoundments For Disposal of High Volume, Low Activity Wastes Similar
to Uranium Mill Tailings.
- Commission Directs Staff to Look at Liberalizing Policy.6
|
|
13
|
- Processing Alternate Feeds At Uranium Mills. The Concept: Wastes Containing Uranium
Can Be Processed Through a Mill To Recover Their Uranium Content, And
the Resulting Tailings and Wastes Can Be Disposed Of As 11e.(2)
Byproduct Material.7
|
|
14
|
- Disposal As 11e.(2) Byproduct Material Effectively Eliminates Long Term
Contingent Liability For the Generator of the Alternate Feed (e.g.,
Liability Under Superfund). Title
to the Waste Passes to Long Term Government Custodian, which is Subject
to Perpetual NRC License.
|
|
15
|
- Under UMTRCA, Material Must be Processed “Primarily” for its Source
Material Content to Generate 11e.(2) Byproduct Material.
- Commission Has Ruled That “Motive” of Licensee for Processing to Obtain
Disposal or Recycling Fee Does not Disqualify a Material from Being Used
as an Alternate Feed.8
|
|
16
|
- As Long as Uranium Will Be Recovered From Alternate Feed Material,
“Sham” Processing is Not an Issue.
- Disposal/Recycling Fees Make It Economically Feasible For Mills to
Process Alternate Feeds -- Now Impossible For Conventional Ores.
|
|
17
|
- NRC Authority to Regulate Tailings And Wastes Generated Prior to 1978 --
i.e., “Pre-1978 Byproduct Material”: 9
- NRC Has Flip-Flopped Position On Jurisdiction Over Pre-1978 Byproduct
Material;
- NRC Previously Asserted Such Material Was Subject to Regulation As
11e.(2) Byproduct Material, and NRC Authorized Disposal in 11e.(2)
Facilities.
- More Recently, NRC Has Allowed Pre-1978 Byproduct Material To Be
Disposed of in RCRA Facilities, Asserting That the Material Is Not
Subject to AEA Regulation as 11e.(2) Byproduct Material.
|
|
18
|
- As a Result of its Flip-Flops, NRC Has Created a Commingled Waste
Problem; 11e.(2) Byproduct Material Has Been Commingled With Non-11e.(2)
Wastes:
- Problems With Dual Jurisdiction;
- Questions Regarding DOE’s Willingness to Take Custody Following Site
Closure;
- Contrary to NRC’s Non-11e.(2) Disposal Policy.10
|
|
19
|
- This Issue Has Raised the Profile of Risk-Informed Regulation in
Congress (i.e., Wastes Posing Similar Risks Should Be Treated in a Similar
Fashion). 11
- To Do So Would Require Major Changes in the Current Rules Because AEA
and RCRA are Definitionally Based
(e.g. NORM mine waste can be virtually identical to 11e.(2) waste, yet
is definitionally different; Same for Listed Versus Characteristic Hazardous
Waste.)
|
|
20
|
- 2. Alternate Concentration Limits (ACLs)
- Under NRC’s Regulations Hazardous Constituents in Groundwater From
Tailings Disposal Sites Must Fall Within Specified Limits at a
Designated ”Point of Compliance” (POC).12
- The Standard Limits That Must be Achieved are Maximum Contaminant Levels
("MCLs"), Background,
Whichever Is Higher;
|
|
21
|
- Or, the Regulations Allow the Licensee to Propose ACLs for One or More
Relevant Constituents;
- ACLs Must Adequately Protect Human Health and Environment at the “Point
of Exposure” (POE), Defined as the Location(s) at Which Humans/Wildlife
Reasonably Likely To Be Exposed.
|
|
22
|
- 3. Alternatives
- Alternatives to NRC Requirements for Disposal of 11e.(2) Byproduct
Materials.
- “A licensee may propose alternatives to specific requirements
[which]…may take into account local or regional conditions.” 13
- These alternatives will be satisfactory if such alternatives:
- “will achieve a level of stabilization and containment of the sites
concerned” and;
- “a level of protection for public health, safety, and the environment
from [the site]”;
- “which is equivalent to, to
the extent practicable, or more stringent that the level which would
be achieved by standards and requirements adopted and enforced by the
Commission or EPA for the same purpose”.
|
|
23
|
- 4. Supplemental Standards:
- EPA’s Regulations at 40 C.F.R. Part 19214 Establish
Groundwater Concentration Limits for Various Contaminants at “Inactive”
(Title I) Uranium Mill Sites;
- These Standards Allow for Natural Flushing and Institutional Controls If
Active Remediation Is Not Appropriate.
|
|
24
|
- When Restoration Of Groundwater To The Limits Established In The
Regulations Is Technically Impracticable, or When the Groundwater Cannot
Be Used For Drinking Because Of Background Conditions, Supplemental
Standards May Be Applied; or
|
|
25
|
- If Achieving The Standards Set Out In The Regulations Would Result in
More Harm Than Good.
- Supplemental Standards Must:
- Assure Protection of Human Health And the Environment;
- Preserve Current And Projected Groundwater Uses.
- Supplemental Standards as an “Alternative” at a Title II Site.15
|
|
26
|
- B. Low Level Radioactive Waste
- 1. NRC Decommissioning & Decontamination Rules.
- 1988 NRC Regulations Defined Decommissioning to Mean “to remove nuclear
facilities safely from service and to reduce residual radioactivity to a
level that permits unrestricted use and termination of the license.” 16
|
|
27
|
- 1993-1994 Concerns About the Pace and Quality of facility
decommissioning and decontamination (D&D) efforts involving NRC,
EPA, DOE, DOD and states led to generic regulatory inquiries to
determine:
- Who must pursue D&D;
- To what level and by what means;
- When D&D should or must take place;
- How much waste will be generated by D&D; and,
- What are the conditions for control or disposal of such waste.
|
|
28
|
- 1994 - NRC’s Timeliness in Decommissioning rule issued requiring
licensed facilities (or portions thereof) that have not been used for
licensed activities for 24 months must begin the D&D process or seek
a waiver. 17
|
|
29
|
- 1994 - NRC proposes “Radiological Criteria For License Termination” 18
- Risk limit (15 mrem/y) Plus ALARA (which=s 3 mrem/y);
- Risk goal (e.g. Like an MCLG);
- Best efforts (e.g. BACT);
- Return to background;
- Possible separate groundwater standard.
|
|
30
|
- 1997 NRC issues final D&D regulations19
- 25 mrem/y for all pathways risk limit for 1,000 years plus ALARA for unrestricted
use;
- A tiered system allowing sites to be released for restricted use under
certain conditions (e.g.. durable institutional controls (ICs) that can
reasonably be expected to be effective into the foreseeable future;
financial assurance; a 100mrem/y fail safe cap if ICs fail;
|
|
31
|
- Costs (including environmental impacts) of unrestricted use of would be
unreasonable; and,
- Must Consult with potentially affected and/or interested members of the
community.
|
|
32
|
- Alternative criteria for license termination other than in compliance
with the 25 mrem/y limit (i.e. reasonable assurance that dose to members
of the critical group will not exceed 100 mrem/y based on comprehensive
risk analysis; ICs to restrict site use, ALARA, detailed public involvement).
- An exception for up to 500 mrem/y in “unusual site specific
circumstances” if approved by the Commission and verification of ICs
every five years.20
|
|
33
|
- Restricted Use and ICs
- NRC D&D regulations21 - Stringent ICs, “such as legally
enforceable deed restrictions” and/or engineering controls backed by
government ownership should be established” “with the objective of
lasting 1,000 years.”
- ICs and controls or barriers that restrict access to the site to limit
potential exposure (e.g. industrial versus residential use or
industrial versus domestic groundwater use).
|
|
34
|
- NUREG 1727 (September, 2000) Chapter 16.0 “NMSS Decommissioning Standard
Review Plan” sets forth restricted use criteria and durable ICs (e.g.,
legal opinion regarding enforceability of IC under particular state
law). 22
|
|
35
|
- “Institutional Controls: A Site Manager’s Guide to Identifying,
Evaluating and Selecting Institutional Controls at Superfund and RCRA
Corrective Action Changes” (September 29, 2000); 23
- Non-engineered instruments such as administrative and/or legal controls
that minimize the potential for human exposure from contamination by
limiting land or resource use;
|
|
36
|
- Even in the unusual case where a CERCLA Record of Decision (ROD) only
requires implementation of ICs, it is considered to be a ‘limited
action’, not a ‘no action’ ROD;
- Informational devices (Deed Notations) are most likely to be used as a
secondary “layer” to help insure the overall reliability of other ICs.
|
|
37
|
- “Protecting Health and Safety with Institutional Controls, Larry Snapf,
NR&E “(Spring 2000)”. 24
- Thus, it is important that the instrument creating the institutional
control identify the party who will have the right to enforce the
restrictions and be responsible for maintaining and repairing the
controls.
|
|
38
|
- Responsibilities of the enforcer may include:
- Making periodic site inspections to ensure that prohibited activities
are not taking place;
- Checking the integrity of caps, fencing and other barriers;
- Ensuring that site use has not extended into prohibited areas; and
- Inspecting drinking water wells to make sure that they are not being
used.
|
|
39
|
- 2. Guidance
- Site Characterization and Cleanup Verification
- Multi Agency Radiation Survey & Site Investigation Manual
(MARSSIM):25
- Excellent discussion of issues, goals, policies and techniques;
- Problematic for demonstrating compliance with 25 mrem/y with naturally
occurring radionuclides.
|
|
40
|
- D&D Code:
- Alternative to RESRAD but is very conservative and impractical -
i.e., One Nuclide and Only homogenous, surface contamination and no
groundwater application.
|
|
41
|
- C. Source Material (S/M) Reconsideration
- 2000 - NRC considers amending 10 CFR 40 requiring NRC approval for
transfers of unimportant quantities (e.g. < 0.05%) of S/M from
licenses to exempt persons.26
- Section 40.13(a) exempts from licensing s/m w/less than 0.05% of U or
Th or a combination thereof.
- Raised question of reducing the licensable level to less than 0.05%.

|
- Draft expresses no preference for permanent remedies;
- Result -- may lead to creation of more Superfund sites.
|
|
49
|
- 2. Council of State Radiation
Control Program Directors (CRCPD) TENORM Model Standards:
- Long term effort cumulated w/proposal from NORM Commission which
utilized NORM Advisory Committee;
- Moved to dose based approach in Final Subpart N Model Regulations.31
|
|
50
|
- No Licensee shall cause a member of the public to receive TEDE from all
licensed sources including TENORM in excess of 100 mrem/y;
- Does not apply to indoor radon or source Material under AEA (i.e., U
& Th) or TENORM regulated under CERCLA or RCRA;
- Release for unrestricted use must assume that reasonable maximally
exposed individual will receive an annual TEDE in excess of “some
fraction” of 100 mrem/y “above background”.
- left states with freedom to choose fraction;
- NJ has chosen 15 mrem/y;
- Incorporates 5/15 pCi/g RA-226 rule for soil contaminated w/Radium.
- Disposal of TENORM in UR tailings impoundment or other AEA licensed
disposal facility or in accordance w/authorized Agency alternatives.
|
|
51
|
- 3. EPA TENORM Project
- EPA published several draft Diffuse NORM Reports such as: “Diffuse NORM
Wastes: Waste Characterization
and Preliminary Risk Assessment” (1993) that were filled with so many
inaccuracies and irrelevancies as to be useless;32
- EPA moving to a series of individual reports on TENORM wastes and
products for different industries:33
- UR is first on the list;
- Designed to be information gathering and not for regulation.
|
|
52
|
- C. Mixed Waste
- Dual Regulatory Scheme imposed by NRC under the AEA and EPA under RCRA;34
- RCRA §1006 mandates that RCRA yield to the AEA to prevent
inconsistencies, however the section has never been used successfully to
exempt materials from regulation under RCRA;
- Has been interpreted to prohibit RCRA regulation only in cases where it
is “physically impossible” to comply with both statutes.
- LLRW standards would provide adequate protection - maybe some EPA
movement in that direction.
|
|
53
|
- D. Radioactive Mine Waste on Federal Lands
- Executive Order 12580 amended by President Clinton to authorize Federal
Natural Resource Trustees and Land Management Agencies to issue
unilateral administrative orders under §106 of CERCLA;35
- April 1998 - Meeting in Grand Junction, Colorado to initiate discussions
about cleanup of inactive and abandoned uranium mines on government
lands pursuant to the above amendment;
- EPA urged federal agencies to pursue clean up under §106 to the 15
mrem/y level;
- Concerns about elevated radionuclide emissions and mobilization of
uranium by acid mine drainage.
|
|
54
|
- E. EPA Maximum Containment Levels (MCLS) for Radionuclides under the
Safe Drinking Water Act (SDWA)
- Tap water standards that will be applied to groundwater corrective
action under CERCLA;
- NRC opposes EPA MCL Package for radionuclides as inconsistent and
outmoded but failure to satisfy MCL’s could leave a terminated NRC
license vulnerable to EPA reopeners.
|
|
55
|
- Radionuclide MCL’s:36
- Radium - 5 pCi/l is retained in spite of evidence of a radium
threshold in humans.
- Uranium - 30 U/g/l (27 pCi/l) will pose a potentially significant
cleanup problem for mining waste operations.
|
|
56
|
- Section 151(b) of the Nuclear Waste Policy Act (NWPA) provides DOE with
the authority to take wastes under certain circumstances.37
- DOE Established a Long-term Stewardship Program under Environmental
Restoration Division to address waste sites that it already must take
(eg.Title I) and those that it may need to take under 151(b).
|
|
57
|
- Critical issues for DOE include:
- Concerns that state may attempt to regulate sites under FFCA for
hazardous materials;
- Concerns that Long-Term Financial Assurance will not be in place;
- Potential Use of trust mechanisms to insure financing.
|
|
58
|
- A. Compacts Have Become Irrelevant
- GAO (September 1999) reports that States have spent almost $600 million
attempting to find and develop about 10 sites for disposing
commercially created LLRW; “none of the states or compacts have
successfully developed a new disposal facility.” “[T]he efforts by states to develop
new disposal facilities have essentially stopped.”38
|
|
59
|
- Barnwell, S.C. facility’s “remaining disposal capacity could be used up
in 10 years.”
- Northwest/Rocky Mountain Compacts - 11 states here use the Richland, WA
facility.
- B. Envirocare is seeking authority to dispose of Class B and C
wastes.
|
|
60
|
- Goal of White Paper: To Proactively Stimulate Conservation of a
Rational, Coordinated Framework for Regulation of UR Activities.
|
|
61
|
- Risk-informed performance based regulation works and has established a
foothold:
- Pre-1978 11e.(2) issue has elevated the risk based regulatory approach
to public debate.
- Performance based licensing is established at NRC even with reactors
(eg. 10CFR 50.59).
|
|
62
|
- The Active controls (i.e., treatment) first in all cases approach is
giving way to less active controls (i.e., ACL’s and IC’s) to remediate
sites in the face of reality.
- Eg; Pump and treat is too expensive and often ineffective so:
- ACL’s;
- Supplemental standards.
|
|
63
|
- Long term stewardship and restricted use make sense:
|
|
64
|
- Duplicative Regulation Will Continue to Be a Problem:
- D&D Rule Conflict
- Mixed Waste
|
|
65
|
- Anything That Resonates Thru CERCLA and RCRA Program That Threatens
Change May Hit a Road Block With EPA.
- Absolute Power Corrupts Absolutely and So It Is With EPA and CERCLA
Which Has Taken On A Deified Life of Its Own.
|
|
66
|
- Huge Volumes of Waste-high Cost of Removal And/or Treatment
(Particularly With NORM) Are Leading to Creative Thinking That Is
Forcing Rigidity of the Past Aside -- So:
- Regulators and Regulated Need to Be Creative and Think Outside the Box;
- Public Opinion Must Be Addressed but More and More Frequently Will
Accept in Situ Closure Rather Than Costs and Risks of Removal;
|
|
67
|
- Flexibility To Address Site-Specific Conditions At Complex Sites (Such
As ACL’s, Alternatives, Supplemental Standards, Restricted Use through
IC’s And Informational Devices.) Is
An Absolute Necessity If Successful Site Closures Are To Be Achieved.
