National: Zero Discharge Effluent
Guideline
Clean Water Act permits:
must meet water quality standards
must meet effluent guidelines
Onshore Oil and Gas Effluent Guideline (40 C.F.R.
§435.32)
“no discharge of waste water pollutants”
exception: “stripper oil wells”
Appalachian Producers requested exemption
“Marginal gas wells” – no action by USEPA
Are Marcellus and Utica Shale wells covered by
effluent guidelines? See September 1976 Development

National: Waste Management
• 1987 – EPA Report to Congress - E&P wastes exempt
from RCRA.
– Recommended working with states to improve state regulation of E&P
wastes.
• Interstate Oil and Gas Compact Commission (IOGCC) –
established waste management guidelines; initiated
audits of state regulatory programs of E&P wastes.
– First review completed in 1991.
– Review completed for Ohio, Pennsylvania, West Virginia, others
• 1999 – State Review of Oil and Natural Gas
Environmental Regulations (STRONGER) succeeds to
IOGCC.
• Currently – State audits ongoing
(NC in Feb 2012).

Ohio

Ohio
• STRONGER Reviews
– 1995
– 2005
– 2011 – Hydraulic Fracturing
8
STRONGER 2011 Ohio Review
Recommendations:
• Complete amendment of hydraulic fracturing
rules
• Consider whether the submittal of MSDS
information is adequate
• Consider providing chemical information from
hydraulic fracturing to first responders.
• Evaluate the need and availability and use of
water for hydraulic fracturing
9
Ohio Program Highlights
June 20, 2010 – S.B. 165 overhaul of oil and gas regulations.
– Increased permitting requirements (urban/non-urban). Fees based on
population size ($250 - $1000).
– Mandatory pooling agreements (additional $5,000 fee), established
minimum acreage units.
– Comprehensive reporting requirements.
– Prohibits introduction of waste fluids into groundwater or surface water.
– Injection disposal fee of $.05 / $.20 per barrel for waste fluids (brine).
– Drill cuttings disposed of on-site or sent to a licensed solid waste landfill.
– Establishes minimum distances for surface locations of wells from
dwellings, RRs, property lines, vessels and other equipment.
– Temporary Inactive Status for wells which are not producing within 1
year of completion.
10
Ohio Program Highlights
•
•
May 16, 2011 – prohibition against discharge of brine wastewater to
POTWs.
February 2012 - Air General Permit to cover shale gas sites. ($2,300).
Permit To Install and Operate – PTIO
– Covers internal combustion, generators, dehydration systems, storage tanks and
flares.
– Does not cover roadways and glycol dehydration units. (But see Proposed
Federal Air rules).
•
March 2012 – Report on Seismic Events near Class II Brine Injection well in
the Youngstown area. Recommendations:
– Enhanced geologic review for new UIC wells, prohibit UIC wells in known faulted
areas, prohibit UIC wells in Precambrian basement, installation of advanced
equipment (auto shut-off, continuous pressure monitoring system, electronic data
tracking system).
•
March/April 2012 – Ohio S.B 315 and H.B. 474 – Proposed modifications of
brine disposal options (recycling, increased fees).
Pending in the legislature.

STRONGER 2010 Pa. Review
Recommendations
• Finalize new regulations for casing and cementing, blow-out
prevention, etc.
• Enhance pre-drilling drinking water well survey requirements.
• Add depth of surface casing and cementing plan to program.
• Assure appropriate chemical information for fracturing is provided
and made available to emergency personnel.
• Require notification to agency prior to hydraulic fracturing operations

process.
• Create a specific secondary containment rule for hydraulic fracturing
tanks.

Marcellus Shale Advisory Commission
July 22, 2011 99 report recommendations
include:

33
Air Emissions and Air Quality
34
EPA Proposed Air Rules
Proposed: July 28, 2011; Final Action: April 3, 2012
• NSPS
– New Source Performance Standards (NSPS) for VOCs
• Applies to new completions and re-completions.
• Requires use of “green completions” equipment to separate
hydrocarbons from flowback/flaring. Does not apply to
exploratory or delineation wells.
• New controls on compressors, pneumatic controllers,
condensate and crude oil storage tanks and natural gas
processing plants.
- NSPS for Sulfur Dioxide – Natural gas processing plants (with
H2S concentration of at least 50%) need to meet sulfur recovery
efficiency of 99.9%.
35
EPA Proposed Air Rules
NESHAP
• Oil & Natural Gas Production
– Remove the 1 ton/year benzene compliance alternative for large
glycol dehydrators.
– Large glycol dehydrators required to reduce toxics by 95%.
– Small glycol dehydrators at major sources – tighter emission
limits.
– Crude oil and condensate tanks reduce toxics by 95%
• Natural Gas Transmission and Storage
- Remove the 1 ton/year benzene compliance alternative for
large dehy units and set tighter emission limits for small units
36
PA Short-Term Ambient Air
Screening
• Key Findings (May 6, 2011):
– Concentrations of certain natural gas constituents
including methane, ethane, propane and butane, and
associated compounds in the air near Marcellus
Shale drilling operations were detected during
sampling.
– Results of the limited ambient air sampling did not
identify concentrations of any compound that would
likely trigger air-related health issues associated with
Marcellus Shale drilling.

CCS
46
Carbon Capture and
Sequestration (CCS)
Regulatory drivers for carbon capture and sequestration
(CCS)
- President’s goal for 83% reduction in CO2 by 2050
- USEPA’s BACT Guidance (November 2010)
- USEPA’s NSPS Proposal (March 2012)
Recent developments
- National Coal Council
- West Virginia CCS Working Group
Implications for oil and gas
47
USEPA BACT GUIDANCE*
• CCS is not in widespread use
• CCS is considered “available” for:
“fossil fuel-fired” power plants
industrial facilities with high-purity CO2 streams (e.g.,
hydrogen production, ammonia production, natural gas
processing, ethanol production, ethylene oxide
production, cement production and iron and steel
manufacturing)
• CCS may be presently available where CO2 can be sold
for EOR
• Research may make CCS more widely applicable in the
future
*http://www.epa.gov/nsr/ghgdocs/ghgpermittingguidance.pdf (December 2010)
48
USEPA NSPS Proposal*
• Proposal limit: 1,000 pounds CO2/megawatthour (30 year avg.)
• Applicable: new fossil-fuel EGUs (boilers, IGCC,
stationary combined cycle units)
• Natural gas combined cycle: no add-on controls
Coal fired units: CCS
*http://epa.gov/carbonpollutionstandard/pdfs/20120327proposal.pdf
49
NATIONAL COAL COUNCIL*
RECOMMENDATIONS:
• Accelerate near term (2015-2020) development of commercial
scale CCS for coal-based generation
• Promote CO2 storage opportunities for EOR
• Exempt CCS from RCRA and CERCLA
• Reduce regulatory barriers with PSD and NEPA
• Allow a CCS permit to authorize use of pore space which is not
being used by its owner
• Limit an operator’s legal liability during operation phase
• Transfer liability during post closure phase
“Expedited CCS Development: Challenges & Opportunities”, March 18, 2011.
http://www.nationalcoalcouncil.org/reports/03_29_11_Final_NCC_Report.pdf
50
WVCCS Working Group*
Conclusions:
• CO2 storage up to 226 years
• Storage below 2500 feet needed for supercritical CO2
• Sequestration operations are similar to oil and gas
operations
• Use of pore space below 2500 feet (not already being
used) should generally be considered public use
• A trust fund should be linked to liability transfer
• A robust regulatory program is necessary
• New legislation is required
* Report to Legislature, July 1, 2011;
http://www.dep.wv.gov/executive/Documents/WVCCS%20Working%20Group%20Final%
20Report%20-%20June%2030,%202011.pdf
51
Implications of CCS for Gas
Industry
• Increase in market share (since no controls will
be needed to meet NSPS for gas fired EGUs)
• CCS deployment will be driven by
– BACT
– NSPS
– on-going debate over climate change
• CCS for EOR may be a “win - win”
• CCS development will be similar to oil and gas
activities
52
Conclusion
53
Conclusion
• States have developed a Shale gas regulatory
program based upon historical approaches
• New legislation has strengthened (and will
continue to strengthen) those programs
• Even with new legislation, continued objection to
horizontal drilling is likely to occur
