Transcript Overview and Implementation of Radium Treatment Residual

Overview and Implementation of the Radium
Treatment Residual Regulations
32 Ill. Adm. Code Section 330.40(d)
Background and Involvement
– Illinois Environmental Protection Agency (IEPA)
• Drinking Water Compliance Section (Radionuclide Rule)
• Water Pollution Control NPDES & Wastewater Compliance
– Illinois Emergency Management Agency (IEMA)
• Environmental Monitoring: Radioactivity in the environment
and around nuclear facilities
• Verification and Oversight for Decontamination and
Decommissioning projects
• Performs site surveys and sampling for license termination
• Inspect/Escort certain classes of Radioactive Materials
Shipments
• Respond / Investigate radiation alarms or allegations
• December 2010, Low Level Radioactive Waste Section to
implement Section 330.40(d)
Topics of Discussion
• How 32 IL Admin Code Section 330.40(d) came about.
• What the Regulations Seeks To Do.
• Specific Provisions and Requirements.
• What is the Scope of Regulated Persons?
• How is This Being Implemented?
• Question / Answer
How Section 330.40(d) Came About:
• 1984 MOA between Illinois EPA and IEMA
– 0.1 pCi/g increase above background for land
application sites.
– Implemented and monitored by Illinois EPA
• 2003 Radionuclide Drinking Water Standards
– Treatment installations/technologies increased
– Radium concentrations in residuals increased
• Municipalities encroached upon 0.1 pCi/g increase in soil
as a result of land application.
How Section 330.40(d) Came About (continued):
• Illinois Pollution Control Board Ruled the MOA an
“Unpromulgated Regulation”
– IEMA evaluated an increase to a 0.4 pCi/g Limit
– Opposition to the proposed rule Increased
• February 28, 2011 - 32 Ill. Adm. Code 330.40(d)
– Provided Exemption from Licensure
– Implemented by IEMA
– Limits the Amount of Radium Land Applied to
1.0 pCi/g increase
– Specifies Avenues for Proper Disposal
– Drinking water AND Wastewater Facilities
What exactly does the new rule do?
• Prior to this exemption, there were no exempt
concentrations or quantities for radium
• Therefore – all radium concentrated from the
treatment of water or sewage was subject to the
licensing requirements of IEMA-DNS
• The Rulemaking is an exemption.
• Provides specific criteria for the disposal of
treatment residuals containing radium less than or
equal to 200 pCi/g and/or land application of
treatment residuals containing radium less than or
equal to 100 pCi/g.

What does the rulemaking do?
(continued)
• Creates an awareness among Drinking Water Treatment
Facilities
– Radium residuals are often far more problematic
• Tracks Radium Land Applications in a manner similar to
Part 391 Metals’ Loadings and Ceiling Limits:
–
–
–
–
–
1.0 pCi/g increase in background radium concentrations
3.0 pCi/g ceiling limit
Up to 100 pCi/g biosolids can be land applied
Up to 200 pCi/g residuals can be landfilled
Monitoring and Reporting to Ensure Limits are Met and
Maintained
Specific Rule Requirements
• Description of each requirement as listed in
Section 330.40(d).
• Short Discussion on the Types of Facilities to
which they would apply.
• Logic and process in which IEMA is
implementing each requirement.
Specific Rule Requirements
• Registration with IEMA
– Owners and operators of plants producing residuals
or sludge from the treatment of water or sewage and
containing radium occurring naturally from
groundwater.
– Owners and operators of IEPA permitted landfills
receiving residuals and/or sludge containing radium

– Disposal in a licensed LLRW disposal facility is
another option
Who is Regulated under Section 330.40(d)?
• Drinking Water Treatment Facilities
– 1. Treatment Technology
– 2. Treatment Technology AND Aquifer
• Wastewater Treatment Facilities
– Only Those Receiving a Treatment Process Waste Stream
from a Drinking Water Treatment Facility Identified in the
Second Category Above.
• Land Applicators
– Anyone who takes the residuals from the generator
– Includes private contractors, golf courses, etc.
– Protects the liability of the generator and land owner
Who is Regulated under Section 330.40(d)?
• Following the Radium Starts at the Drinking Water
Treatment Facility.
• Not just MCLs or Radium Treatment
• Groundwater Treatment Only.
• Define the Treatment Technology
• Define the Aquifers
Drinking Water Treatment Media can far
Exceed Wastewater Sludge Concentrations
Drinking Water Treatment Media
• Responses include facilities NOT treating for
radium
• Include Southern Illinois Communities
• Facilities treating for radium have been working
with IEMA to avoid creating residuals in excess of
200 pCi/g
• Many Drinking Water Facilities are not aware of
Radium Accumulation until Refused for Disposal
• Radium Removal Systems Pose the Largest
Disposal Problems in Backwash Holding Tanks
Drinking Water Treatment Media (continued)
• Even low levels of radium can be concentrated over
time.
• Therefore, treatment is the first criteria for inclusion in
regulatory scheme.

• List Continually Refined and Residuals Sampled.
Drinking Water Treatment Media (continued)
• If a Drinking Water Treatment Facility utilizes one of
these treatment technologies, the media itself must be
monitored prior to disposal. (the sand, gravel bed, filter,
resins, etc.)
• Screening is acceptable for landfill disposal.
• These residuals not typically land applied.
– Lime Softening Exemption
• If the aquifer from which the facility draws source water
is not identified by the USGS as having elevated radium
concentrations from surrounding bedrock,
– No Wastewater Treatment Plant Registration
– No Land Application Requirements on the Sludges.
Drinking Water Treatment Facilities
• If the aquifer from which the facility draws source water
is identified by the USGS as having elevated radium
concentrations from surrounding bedrock...
– Any wastewater treatment facility receiving a waste
stream is a registrant as well.
– Any land applications or landfill disposals are
regulated under Section 330.40(d).
– Field Sampling and Tracking Radium Accumulation
for Drinking Water and Wastewater Sludges
Aquifers Designated by IEMA

Lacking a Regulatory “Box”
• Working with Individual Systems
• “CCA” Approach
• Case Specific Exemptions
– Sludges Beneath 3 pCi/g
– Land Application (and Lime) from Drinking
Water Facilities using ‘Treatment Only’
• Unique Circumstances by Design
