Environmental focus
stronger in some regions
Large gas plays, in close proximity to urban or pristine areas with little local familiarity to the O&G
industry are likely to draw the most intense scrutiny

Shale Gas: Federal Regulatory
……and is using it
EPA has authority to
Overview
regulate…..
Safe Drinking Water Act: Fracking
cannot be regulated except where
diesel fuel used
Proposed SDWA guidance requires permits if diesel use;
produced water can be regulated under existing rules
Clean Air Act: EPA can
regulate emissions from O&G
operations that are “major
sources”
Clean Water Act: EPA can
regulate direct and indirect (thru
POTWs) discharges
New rules require “green completion” or flaring at wells
until 1/1/2015; both after that date; more stringent
emission limits for gathering and processing facilities
Current rules prohibit direct discharges; indirect
discharges currently unregulated, but pre-treatment
standards being developed, likely in 2014
Toxic Substance Control Act:
EPA has broad authority for
chemical testing/disclosure
NGOs petitioned for chemical testing/use disclosure in
all O&G exploration/development; EPA denied testing
but granted disclosure/reporting request
BLM has power over Federal lands
…..
BLM has broad powers over
activities on federal lands—
38% of US gas wells on
federal land
..…and it too is using it
Proposed rule issued in May would require chemical
disclosure, data submission on geology/well integrity,
and BLM operational approvals

Shale Gas: State Regulatory
• Ohio has comprehensive new law
Developments
 covering chemical disclosure
 waste disposal (including for
underground injection well
owners)
 well construction requirements
 pipeline safety requirements
 local approval of permits but not
a severance tax
• New York moving to allow shale gas
development in some counties

GE solutions for water issues
• Source water filtration to reduce chemical pretreatment
• Water reuse/recycling
• On-site mobile evaporators
• Fixed evaporation & crystallizers
Challenge - filter hydraulic fracturing
source water to reduce chemical treatment
and cost and meet environmental
regulations
Solution - mobile ultra-filtration systems
Challenge - cost effectively
treat produced and
flowback water for reuse or
discharge
Solution - mobile and fixed
membrane systems and
thermal evaporators with
service contract
Mobile Evaporator
Challenge - reduce operation
costs through solid and bacteria
removal
and chemical reduction
Solution - one pass filtration
