4. What is Hydraulic Fracturing?
âHydraulic Fracturing is a well stimulation process
used to maximize the extraction of underground
resourcesâ (EPA)
Fracking is the process of using explosive
charges, followed by the injection of millions
of gallons of water, sand, and chemicals to
break up rock miles beneath the surface of
the earth. Horizontal drilling allows shale gas
or shale oil to be extracted and pumped to the
surface, along with the fluid used in the drilling
operation. (University of Connecticut)
5. General Oversight & Regulation
ď Notification and reporting requirements during
cementing, well completion, well stimulation and well
production (ODNR)
ď Site restoration is required for urban and non-urban area
well sites (ODNR)
ď Water withdrawal: the law requires registration if a facility
has the capacity to withdraw 100,000 gallons per day
(ODNR)
ď Air: permit-to-install and operate required for units or
activities that emit air pollutants (Ohio EPA)
ď Radioactivity: solid waste disposal (ODNR, Ohio EPA, ODH)
*Source of information: Ohioâs Regulations: A Guide for operators drilling in the Marcellus & Utica
Shales. Ohio EPA. March 2012.
6. What are shale gas waste streams?
ďś Brine: Salt water (EPA)
ďś Flowback fluid: Recovered fracturing fluids, also called produced
water (EPA)
ďś Drilling mud/fluid: A mixture of liquids and gaseous fluids and
mixtures of fluids and solids used to drill into the earth. (Oilfield
Glossary)
ďś Note: All three also likely to include fracking chemicals, heavy metals &
radiological materials
Flowback Fluid
7. More Fracking Terms
ďś Drill cuttings: Rocks and soil that are brought to the surface during
drilling activity (US EPA)
ďś Pipe scale: Material that builds up on the inside of pipes. This
material makes the inner area of the pipe smaller, which increases the
pressure inside the pipe. (US EPA)
Pipe ScaleDrill cuttings in an open pit
8. Temporary Storage for Fracking Wastes
ďś Impoundments: are used to contain millions of gallons of water
and recycled natural gas drilling wastewater. (Marcellus-Shale)
ďś Open Pits: holds fracking fluids and drill cuttings, may be lined, but
can overflow and leak into the soil (OSHA)

10. Radioactivity in Black Shales â
where does it come from?
⢠We are Stardust
⢠So is everything around
us, including black
shales
⢠Hydrogen to Boron
formed in the Big Bang
⢠Carbon and all the rest
form during the life of a
star & are released at
itâs death â a Supernova
11. Black Shales are Radioactive
two ways
⢠From their parent source
rocks
⢠Devonian Marcellus â
Appalachian uplifts
⢠Silurian Utica â earlier
mountain building &
Canadian Shield
⢠From Bioaccumulation
⢠Black shales and coals are big,
dirty, old activated carbon filters
⢠As surface & ground water
carrying soluble heavy &
radioactive metal cations move
through the shales, the organic
carbon, a very strong negative
magnet, releases small & light
cations and binds bigger &
heavier cations
⢠The older the rock & higher the
carbon content, the more the
radiation, sources being equal
⢠The higher the sources, the more
the radiation
12. 2013 Focusing on Shale Gas Wastes
⢠Ground Shale Rock: hydrocarbons, heavy &
radioactive metals, OhioâNORM, US EPA-TENORM
⢠Drilling Muds & Sludges: who knows what,
TENORM
⢠Fracking Fluids: water, sand, who knows what, if
recycled, are they-NORM, US EPA-TENORM
⢠Brine: salts, hydrocarbons, heavy & radioactive
metals, Ohio-NORM, US EPA-TENORM
⢠Drilling Site Wastes & Accidental Releases:
who knows what is being released
⢠Where are they coming from?
⢠Where are they going?
13. Why the NORM â TENORM
Confusion?
⢠Four National Definitions for NORM-TENORM
⢠Ohio uses Conference of Radiation Control
Program Directors, 1990, least restrictive
⢠US EPA, Nat. Academy Sci and ANSI all add to
NORM âpotential for increased exposureâ making
whole waste stream TENORM & subject to testing
⢠5 pCi/g (US EPA clean-up standard) & 5 pCi/L (US
EPA Drinking Water MCL) would apply to whole
waste stream*
⢠* pCi/g or L, picoCurie/gram or Liter
14. ⢠Ohio has paid for State & Local governments
by taxing (tipping fees, etc.) out of state waste
streams (solid, C&DD, industrial, medical, O&G, etc.)
for last 20+ years
⢠Shale Gas drilling has created a big, new
waste stream not addressed by surrounding
states - seen as a new & easily captured revenue
source by Ohioâs Administration
⢠Ohio DOES NOT have magic GEOLOGY
â that can swallow all wastes without repercussions
Why the Current Concern?
15. Why the Current Concern Cont?
⢠Blacks shales are early sources of Uranium ore
for the âAtomic Ageâ (Chattanooga Shale, TN; USGS,
1961)
⢠Black shales like coal are full of heavy and
radioactive metals: 232Th to 228Ra & 238U to 226Ra are
most common series
⢠228Ra, 238U & 226Ra water soluble, also in brines
⢠US EPA limit on Uranium mill tailings, 5 pCi/g
because of the Radium: > LLRW Landfill, Utah or
Washington State accept NORM
⢠US EPA Drinking Water MCL 5 pCi/L for Radium
16. Figure 1. Graph from Radioactive Elements in Coal and Fly Ash:
Abundance, Forms, and Environmental Significance. U.S. Geological
Survey Fact Sheet FS-163-97. October, 1997
17. Why the Current Concern Cont?
⢠NY brine up to 15,000 pCi/L
226Ra
⢠Hard scale in used drilling
pipes up to 6,000 pCi/g 226Ra
and up to 2,000 pCi/g 228Ra â
requires TENORM handling
⢠Ohio still contaminated

20. Shale Gas Wastes: A Growth
Industry for Ohio
⢠Wastes coming into Ohio by road, rails &
soon by river barge, port Washington Co.

⢠Over 52% 2012 injections in Class II
wells came from out of state, mostly PA &
WV
⢠Dedicated out-of-state Class II wells
being installed in SE Ohio (new one
Athens Co.)
21. Shale Gas Wastes: A Growth
Industry for Ohio cont.
⢠No Public Hearings being held for anyone
⢠With NY still to be decided & barge ports
for Ohio River/Gulf wastes coming on line

23. Drillers: Ohio easy place to do
business in (Cols Dispatch, 5-1-13)
⢠âOhio is probably the most regulatory-
friendly state Iâve operated inâ, Randy
Albert, Consol Energy, PA
⢠âTo its credit, DNR has sought more
regulatory power over this industryâ, Jack
Shaner, Ohio Environmental Council
⢠âBut some of those attempts have met
resistance from majority Republicans in
the Ohio General Assemblyâ, Dan Gearino,
Cols Dispatch
31. Injection Well 1st Step:
Surface Casing
⢠Surface casing is the first casing installed in
the well. A hole is drilled from the surface to
below the base of the lowest aquifer. The
surface casing is installed in the borehole, and
is sealed into the hole with cement.
⢠Cementing is the introduction, usually from
the bottom-up, of neat Portland cement (not
concrete) and mineral additives, that serve to
seal the casing to the formations exposed in
the borehole.
32. 2nd Step: Long-String
Casing
⢠Long-string casing is installed within the
surface casing -imagine a pipe within a
pipe. The cementing plug is drilled out and
drilling continues through the confining
zone to the injection interval. The long-
string casing is installed from the surface
to (or through) the injection zone, and is
sealed into the drill hole with cement.
33. 3rd Step: Injection Tubing
⢠Tubing is the smallest diameter pipe in the well. Tubing is installed inside the long-string
casing, and carries the injectate from the surface to the injection zone. It is usually constructed
of corrosion-resistant steel or fiberglass-reinforced-plastic, and is typically 2-1/2 to 7 inches in
diameter.
⢠The packer is a mechanical device that seals the outside of the tubing to the inside of the
long-string casing, near the bottom of the tubing.
⢠The wellhead seals the gap between the tubing and long-string casing, at the top of the
tubing.
⢠The packer annulus is the space between the outside of the tubing and the inside of the
long-string casing. The annulus is sealed at the top by the wellhead, and at the bottom by the
packer. Pressure can be maintained on the annulus, and monitored by the injection well
operator. Any change in pressure indicates a leak in the system. An analogy is the pressure
you maintain on the annulus of your automobile tires. A flat tire indicates a defect in either
the tire or the rim. Similarly, monitoring the annulus pressure provides a continuous
measurement of the internal integrity of an injection well.

36. Safe Drinking Water Act (SDWA)
The Safe Drinking Water Act (SDWA) is the main federal law that ensures the
quality of Americans' drinking water. Under SDWA, EPA sets standards for
drinking water quality and oversees the states, localities, and water suppliers who
implement those standards.
SDWA was originally passed by Congress in 1974 to protect public health by
regulating the nation's public drinking water supply. The law was amended in 1986
and 1996 and requires many actions to protect drinking water and its sources:
rivers, lakes, reservoirs, springs, and ground water wells.
37. â Supplies any public water system or contains a quantity of
ground water sufficient to supply a public water system
(SDWA does not regulate private wells which serve fewer than 25 individuals.)
PUBLIC
39. In 1974, responding to concerns about underground injection practices, including
failure of some wells, the U.S. EPA raised concerns that injected waste could
contaminate underground drinking water.
In December 1974, Congress enacted the Safe Drinking Water Act, which required
the EPA to set requirements for protecting underground sources of drinking water.
EPA passed its Underground injection Control regulations in 1980.
In 1988 EPA made its UIC regulations stronger to comply with the newly upgraded
waste disposal amendments of the Resource Conservation and Recovery Act.
In 1988 EPA exempted E&P waste from oil and gas from requirement under
Subtitle C of RCRA.
40. In its 1988 Regulatory Determination, EPA admitted that E&P
wastes contain toxic substances that endanger both human health
and the environment. Despite noting that benzene, phenanthrene,
lead, arsenic, barium, antimony, fluoride, and uranium found in
E&P wastes were of major concern and present at âlevels that exceed
100 times EPAâs health based standards,â EPA declined to regulate
these toxic substances under Subtitle C of RCRA.
EPA identified three factors as the basis for its decision not to
regulate E&P wastes under Subtitle C. These factors included:
(1) the infeasibility of implementing alternative regulations,
(2) the adequacy of state regulations,
(3) the economic harm that would befall the oil and gas industry if
additional regulatory controls were imposed
41. Recycling of Fracking Fluids
⢠Chesapeake in Carroll County, Ohio
⢠Range Resources in PA
⢠Consol/Epiphany/PMC Biotech solar
powered recycling pilot plant started
in July 2012 in PA
⢠Number of others as well
Why? Because they need the water for the
next well & savings on reclaimed
chemicals
42. Potential Problems from Recycling
⢠Recycled fracking fluids need to be filtered
â to remove sand, rock cuttings, etc. before being reused
⢠Filtered materials go to landfills
⢠Reusing the fluid increases the levels of
Radium each time through, not removed
⢠Eventually TDS etc. so high that fluid must
be disposed of in Class II wells anyway
⢠Ohio not collecting information on Recyclers
â who/where they are, how they collect fluids, how dispose of
wastes, etc.
43. The Patriot Water Treatment /
Warren, Ohio WWTP Process
⢠Fracking flowback water is trucked to the Patriot
Facility in Warren
⢠Flowback is filtered & blended & sent to Warren
WWTP where discharged to Mahoning River
⢠Where does filter cake go?
⢠Patriot & Warren WWTP check for radium w/
handheld monitor which underreports
⢠OEPA says ODH approved, ODH says ODNR
approved, ODNR not qualified to approve
radiation monitoring or managing of WWTPs
⢠No one knows how much radium is being
discharged into the Mahoning River at Warren
44. Our Studies Show Real-Time
Measurements at Landfills & WWTPs
are Unreliable
Radium emits alpha &
beta, not a strong
gamma emitter
Requires Ra-226 to Rn-
222 to Po-218 to Pb-214
or Bi-214 decay to get
good measure
Standard is 21-days
holding time in sealed
jar in lab for reliable
levels
45. Repurposing of O&G Brine
⢠Almost everything in O&G brine has an
industrial application & a current
market
⢠Already âmineâ salts in Ohio for
industrial applications
⢠DOE/GE working on process to remove
Radium-228 and 226 from brine
⢠Technology already exists to break
O&G brine down, working on
economics
46. Repurposing of O&G Brine cont.
⢠Why dispose of resources we need &
would have to make/extract in other
ways for other costs?
⢠Ohio could still extract âtaxâ for out-
of-state brine if reprocessed here,
real jobs for Ohio
47. Legal disposal for shale
rock cuttings, drilling
muds and associated
wastes
Am. HB 59 requires
downblending if Ra
levels above MCLs for
TENORM only, NO
TESTING for NORM
No requirement that
chemical binding of
radioactive materials to
dilution materials must
occur
Landfilling the Wastes
48. But are they Low Level
Radioactive Waste Landfills?
⢠No solid waste and

49. How Long to Protect from Human
Interaction if We use Michiganâs 50
pCi/g Landfill Limit
⢠50 pCi/g to 25 pCi/g to 12.5 pCi/g to 6.25 pCi/g to 5
pCi/g: 3+ half-lives
⢠50 pCi/g Radium-226 to 5 pCi/g ~5,000 yrs, back to
the beginning of Egypt's pyramids
⢠50 pCi/g Uranium-238 to 5 pCi/g, 3+ half-lives, back
to the beginning of the Universe
⢠50 pCi/g Thorium-232 to 5 pCi/g, ~45 Billion years,
more than the diameter of the visible universe

My thoughts are that they are the same thing except "open pits" is an older term and included all the unlined pits of the 60's and 70's and before. At this point everything that is not "fresh water" (and there are questions about what fresh water is), has to be lined but that does NOT mean that the linings don't leak. In fact, based on the US ACE HELP model for landfill liners, we assume that they leak. This makes the "frac tanks" a better choice, but of course, they can also leak and/or have spills in the emptying and/or filling process so none of this is leak free.JulieWater stored here may be recycledMarcellus Shale: http://www.marcellus-shale.us/impoundments.htmOSHA: http://www.osha.gov/SLTC/etools/oilandgas/drilling/drillingfluid.htmlPictures:Open pit: http://www.catskillmountainkeeper.org/our-programs/fracking/whats-wrong-with-fracking-2/wastewater/Impoundment dam: http://www.marcellus-shale.us/disposal-wells.htm
