Oil and Gas Annual Report 2013 - Pennsylvania

Message from DEP Secretary Chris Abruzzo
It is hard to imagine that less than five years ago, most Pennsylvanians were
unfamiliar with terms such as “Marcellus Shale” and “hydraulic fracturing.”
Today, most of us are not only familiar with these terms, but many have
witnessed the steady transformation of this state into the second largest natural
gas producing state in the nation. We are in the midst of an energy revolution
that is bringing new jobs to Pennsylvania, spawning new economic development
and growth, and providing energy security to our nation. At DEP, we are at the forefront of this
revolution, charged with ensuring that this vast energy resource is produced in an
environmentally responsible manner.
Since joining the Pennsylvania Department of Environmental Protection (DEP) in April 2013, I
have met with staff from across the agency to review our programs and identify ways in which
we can perform our mission better. I am pleased to work alongside so many dedicated public
servants who care about our environment and utilize their problem solving skills to protect our
environment and facilitate responsible development across Pennsylvania.
We are one DEP…. as such, it is our collective mission to protect Pennsylvania’s air, land and
water from pollution and to provide for the health and safety of our citizens. We are to
guarantee that all Pennsylvanians, including future generations, have a safe, healthy
environment. We are to work as partners with individuals, organizations, governments and
businesses to achieve a balance in preventing pollution and restoring our natural resources,
while carrying out these responsibilities in a fair and timely manner that respects both the
environment and the regulated community, and is deserving of the public’s trust.
I hope you find this 2013 Oil and Gas Annual Report to be informative and insightful about
DEP’s Oil and Gas Program and how we are fulfilling our mission. This report provides
information about how we authorize and inspect oil and gas exploration and production
operations in the commonwealth. You will also learn about innovative approaches that have
been implemented by DEP and get a glimpse of what to expect during 2014.
Calendar year 2013 was a productive one and DEP continues to build on our past
accomplishments to achieve even greater successes during 2014!
Enjoy,
E. Christopher Abruzzo
Secretary

PENNSYLVANIA’S ENERGY LANDSCAPE:
The exploration and production of energy sources is not new to Pennsylvania. In fact, the first
commercial oil well was successfully drilled in 1859 by Edwin Drake in Titusville, Pennsylvania.
This was the birth of what was to become the nation’s petroleum industry.
During the late 1800s, Pennsylvania was the nation’s leading producer of crude oil with
production levels peaking in 1891 at approximately 31 million barrels; about 58 percent of the
nation’s total oil capacity. By the early 1900s, major oil fields were discovered in Texas,
Oklahoma and California that shifted exploration and production activities to the mid-west and
western portions of the country. Pennsylvania’s crude oil production quickly waned as
exploration and production of new oil fields opened up in other parts of the country.
As conventional oil reserves in Pennsylvania became less productive, new techniques and
practices were used to “flood” unproductive wells with surface water to push oil to the surface.
Although the productivity of oil wells in Pennsylvania continued to decline throughout the
remainder of the 20th
century, conventional oil reservoirs in the state continued to yield a
sufficient volume of oil to support a viable oil industry. During 2013, almost 5 million barrels of
crude oil were produced in Pennsylvania.
In addition to historic oil reserves, Pennsylvania has also been a source of natural gas for well
over a century. Although natural gas was routinely encountered by early oil developers, it was
initially considered to be more of a nuisance than a resource. As methods improved for
capturing, transporting and using natural gas, a modern natural gas industry began to emerge.
It was long suspected that deposits of natural gas existed within vast tight shale formations
deep under Pennsylvania’s surface; however, conventional extraction methods were not able to
effectively unlock the natural gas from its source and the actual quantities were not well
understood.
Today, these black shale deposits are called “shale plays” and are referred to by their geological
naming conventions such as the “Marcellus Shale” play and the “Utica Shale” play. The term
“unconventional” refers to these same shale formations that utilize horizontal drilling methods
and hydraulic fracturing techniques to break up the shale rock to allow the natural gas that is
trapped within the target formation to flow more freely to the well bore.
It was not until recently that effective drilling and hydraulic fracturing techniques could be
successfully and economically deployed to capture natural gas from these shale deposits. In
2004, the first unconventional natural gas well was developed in Pennsylvania and positive
results led to additional unconventional wells being constructed. Within several years, a
renaissance in natural gas production emerged in Pennsylvania making it a dominant supplier of
natural gas to the nation. The successful production of unconventional resources such as the

3 | P a g e
“Marcellus” and “Utica” shale plays are transforming not just the United States, but indeed the
world.
In Pennsylvania, natural gas operators are reporting increased production rates that are
expected to rise over the coming years. In 2013, Pennsylvania produced over 3 trillion cubic
feet of natural gas.
ADVANCING OUR ENERGY SECURITY:
Today, much of the nation’s oil production occurs in states such as Texas, North Dakota,
Oklahoma, California and Alaska; however, Pennsylvania’s conventional “oil patch” in the
northwest corner of the state continues to yield crude oil. Since this crude oil is paraffin-based,
it is renowned for its lubricating qualities and is used in the manufacture of petroleum
lubricants such as motor oils and as an ingredient in consumer products such as cosmetics,
ointments and lotions. Pennsylvania’s oil producers typically use conventional drilling methods
that have not changed much over the past century to capture this resource.
Since 2008, Pennsylvania’s natural gas production has increased exponentially as a result of
unconventional drilling techniques including hydraulic fracturing and horizontal drilling. This
increasing trend in shale gas production is resulting in energy security that translates to
national security in the form of less dependence on fossil fuels from other parts of the world.
Increased shale gas production has resulted in a number of significant benefits including less
expensive energy costs and improvements to Pennsylvania’s air quality as a result of the
increased use of cleaner burning natural gas.

Pennsylvania’s legislature passed several significant amendments to the state’s oil and gas laws
with Act 13 of 2012. This law, for the first time, included an “impact fee” that is paid for by the
natural gas industry to offset the costs of the impacts to local communities and counties where
natural gas drilling occurs. During the past three years, more than $630 million has been
collected by the commonwealth and these monies have largely been allocated to
Pennsylvania’s counties and municipalities, in addition to providing funds to support state
agencies and organizations that oversee natural gas drilling activities in Pennsylvania. DEP
receives $6 million annually in new revenue from the impact fee.
Pennsylvania’s natural gas reserves are significant compared to other shale gas plays across the
country; however, it is not a limitless resource nor is it the only energy resource on which this
nation relies. Currently, there is no single energy source that can solely meet the energy
demands of the United States, let alone the entire world. Although the production of oil and
natural gas provides tangible benefits, it must be done in a way that is protective of
Pennsylvania’s citizens and the environment.
DEP’s MISSION:
The mission of the Department of Environmental Protection (DEP) is “to protect Pennsylvania's
air, land and water from pollution and to provide for the health and safety of its citizens
through a cleaner environment. We will work as partners with individuals, organizations,
governments and businesses to prevent pollution and restore our natural resources.”
DEP plays a vital role in the comprehensive oversight and regulation of the oil and gas industry
in Pennsylvania. Although there are some related federal statutes that affect the oil and gas
industry, most laws and regulations that pertain to the oversight and regulation of the oil and
gas industry in Pennsylvania reside at the state level.
In Pennsylvania, DEP is the primary agency that is responsible for issuing permits that are
required prior to the construction and operation of oil and gas wells; and DEP is the primary
agency responsible for inspections at well sites. There are other agencies and organizations in
Pennsylvania that are responsible for various other roles – including the Pennsylvania Public
Utility Commission (PUC), the Department of Conservation and Natural Resources and regional
river basin commissions to name a few. However, DEP is the primary state agency that is
responsible for regulating the construction of well sites and conducting regular inspections to
ensure that well sites are operated in a manner that is safe for Pennsylvania’s citizens and
protective of the environment.
PUC and the Federal Energy Regulatory Commission (FERC) also play an important role in terms
of inspections of natural gas transmission pipelines in Pennsylvania. Although DEP is
responsible for inspections of the construction of natural gas “gathering” lines, PUC is
responsible for safety inspections of intrastate natural gas transmission lines that carry natural

5 | P a g e
gas to local markets, and FERC is responsible for inspections of interstate natural gas
transmission lines that move natural gas to regional and national markets.
DEP’s STRUCTURE:
The Office of Oil and Gas Management was established as a result of the departmental
reorganization in 2011 and, for the first time, the Bureau of Oil and Gas Management was
elevated to a deputate-level
program. The current organization
chart for the Office of Oil and Gas
Management is depicted to the
right.
DEP’s Office of Oil and Gas
Management employs 202
individuals of which approximately
80 percent of are assigned to
engineering, scientific or
permit/inspection-related work
and the remaining 20 percent
provide administrative, legal and clerical support. The office consists of two overarching
bureaus. The Bureau of Oil and Gas Planning and Program Management is located in central
office (Harrisburg) and is responsible for the administrative, policy and regulatory development
functions. The Bureau of District Oil and Gas Operations consists of three district oil and gas
offices and is responsible for all permitting, inspection, compliance and enforcement functions.
The Bureau of Oil and Gas Planning and Program Management includes the following three
divisions:
 Well Development and Surface Activities – This division is responsible for developing policies
and guidance related to surface activities associated with oil and gas well site design and
construction. This includes engineered well pad components such as erosion and sediment
control structures, pits and impoundments. Staff in this division advise district permitting
and inspection staff to ensure that best management practices and controls are
implemented on wells sites to reduce and minimize surface erosion from entering the
state’s waterways.
 Well Plugging and Sub-Surface Activities – This division consists of the Subsurface Activities
Section and the Well Plugging Section. The Subsurface Activities Section is responsible for
the management of subsurface oil and gas related program services and activities and offers
expertise in the subjects of drilling, casing, cementing, completion, stimulation, workover,
and production activities and operations associated with conventional and unconventional

6 | P a g e
hydrocarbon formations in Pennsylvania. The Well Plugging Section maintains and
implements the successful Orphan and Abandoned Well Plugging Program.
 Compliance and Data Management – This division works closely with DEP’s Bureau of
Information Technology to oversee the operation and maintenance of data management
systems and databases that track production data that is submitted by the regulated
community. This division also runs weekly workload analysis reports, develops interactive
reporting tools, prepares statistical and graphical analyses, and maintains the oil and gas
website.
The Bureau of District Oil and Gas Operations includes three district offices that implement the
operational programs in the Eastern, Northwest, and Southwest areas of the Commonwealth.
Staff in the district offices conduct the functions of permitting, inspections, compliance and
enforcement and are based in Williamsport, Meadville and Pittsburgh. Several small field
offices are located in each of the district geographic areas to enable DEP to more effectively
implement its inspection and compliance programs and oversight of the regulated community.
DEP’s OIL AND GAS PROGRAM - A WORLD CLASS LEADER:
Pennsylvania is recognized nationally and internationally as having successfully developed a
regulatory approach that both protects its environment and citizens while also providing for
optimal development of oil and gas resources. Over the past several years, representatives and
officials from many countries around the world have traveled to Pennsylvania to meet with
DEP’s Office of Oil and Gas Management to learn more about its programs and practices.

7 | P a g e
Closer to home, DEP’s regulatory approach has served as a model to other state environmental
agencies as well. In May 2013, the State Review of Oil and Natural Gas Environmental
Regulations, Inc. (STRONGER) conducted a programmatic and regulatory review of DEP’s Oil
and Gas program. STRONGER is a non-profit, multi-stakeholder organization whose purpose is
to assist states in documenting the environmental regulations associated with the exploration,
development and production of crude oil and natural gas. The organization shares innovative
techniques and environmental protection strategies and identifies opportunities for program
improvement. The state review process is a non-regulatory program and relies on states to
volunteer for reviews.
On Sept. 20, 2013, STRONGER published the results of its most recent independent peer review
of DEP’s oil and gas regulatory program at www.strongerinc.org and found it to be proficient
and ready to address the increase in oil and gas operations in Pennsylvania. This represents the
fifth review of Pennsylvania's oil and gas program since 1990.
STRONGER recognized the following actions taken by Pennsylvania’s Oil and Gas program to
strengthen the following key areas:
 Increased staff levels to address additional permitting, inspection and enforcement
activities related to increased unconventional gas well development;
 Expanded the program’s public participation activities associated with the abandoned
well sites program;
 Initiated a comprehensive evaluation of radiation levels specifically associated with
unconventional gas development, the first of its kind in the nation;
 Mandated that operators performing earth disturbance activities associated with oil and
gas activities develop and implement erosion and sedimentation control best
management practices to minimize the potential for erosion and sedimentation; and
 Advanced its hydraulic fracturing program and required that well operators conducting
well casing and cementing to maintain control and prevent migration of gas or other
fluids into sources of fresh groundwater.
PENNSYLVANIA’S SHALE PLAYS:
Unconventional shale basins are commonly characterized according to the geologic formation
that serves as the source of its shale gas. The term “shale play” is used by the oil and gas
exploration and development industry to identify areas of shale basins that appear to be
particularly suitable for shale gas development. The current predominant shale play in
Pennsylvania is the “Marcellus Shale Play;” however, interest is beginning to increase in the
exploration and production of the “Utica Shale Play” that lies well below the Marcellus Shale
Play. There are other less familiar shale plays in and around Pennsylvania including the

8 | P a g e
Rhinestreet, Huron and a collection of less extensive formations that comprise the Upper
Devonian shale formation.
The type of gas found in most areas of the Marcellus Shale Play throughout Pennsylvania is
geologically mature and consists of mostly methane that requires little processing prior to use.
This gas is commonly called “dry gas.” Marcellus shale gas found along the westernmost border
of Pennsylvania is less geologically mature; therefore, in addition to methane, the gas contains
additional hydrocarbons such as ethane, propane and butane. This gas is commonly called “wet
gas” and can be used to produce plastics and other high value petroleum-based products. Given
the current spot market price of petroleum feedstocks, the value of wet gas is significantly
more valuable than dry gas.
Although the Marcellus Shale Play overlies the Utica Shale Play, both stretch from the eastern
portions of Ohio and West Virginia through the southwest to northeast corners of Pennsylvania
and terminate in southern New York State.
PERMITTING:
The Office of Oil and Gas Management is responsible for the review of all permit authorizations
related to the construction of oil and gas wells and development of the sites on which they are
Map depicting Unconventional Shale Plays in the Northeast

9 | P a g e
constructed. Although there are many types of permit authorizations that are issued by
permitting staff within the Office of Oil and Gas Management, the two permits that are most
commonly issued by DEP include the “Erosion and Sediment Control General Permit–2” and the
“Drill and Operate a Well” permit (commonly called the Well Drilling Permit). Although not
technically a permit, the Office of Oil and Gas Management also operates a well plugging
program that requires entities that intend to plug an orphaned or abandoned well to submit
formal notification to DEP. Due to its significance, a summary of DEP’s well plugging program is
included in this section along with a description of the Erosion and Sediment Control General
Permit–2 and the Drill and Operate a Well permitting programs.
Erosion and Sediment Control General Permit-2 (ESCGP-2)
The Erosion and Sediment Control General Permit-2 (ESCGP-2) is designed to address earth
disturbances at oil and gas sites where more than 5 acres of land are disturbed. This general
permit is typically used to authorize an operator to construct unconventional gas well pads and
associated pipelines, retention basins, pits and impoundments.
On Dec. 29, 2012, the department published as final, the ESCGP-2 and revisions to the “Policy
for Erosion and Sediment Control and Stormwater Management for Earth Disturbance
Associated with Oil and Gas Exploration, Production, Processing, or Treatment Operations or
Transmission Facilities” (hereafter, stormwater policy). The ESCGP-2 permit and associated
stormwater policy were developed concurrently and incorporated significant stakeholder input
that was received during 2012. The ESCGP-2 permit was developed to replace Erosion and
Sediment Control General Permit–1 (ESCGP-1) that expired on April 12, 2013. The revisions to
the stormwater policy were the first since July 2003 and were intended to address the type and
scope of oil and gas activities currently occurring in Pennsylvania. Industry training related to
the new permit and stormwater policy was held throughout 2013.
The standard permit review timeframe for an ESCGP-2 permit is 43 business days. DEP offers an
expedited review process whereby a permit decision can be reached in 14 business days
provided the project achieves the permit standards and ensures protection of the environment.
In certain situations, such as when a well site is in close proximity to high quality or exceptional
value waters, the expedited review process is not available to the permit applicant.
In 2013, DEP issued 287 ESCGP-1 permits and 460 ESCGP-2 permits. Since 2013 was the first
year that the ESCGP-2 permit was created and in use, the department will evaluate the long-
term permit trends as more information becomes available.
Drill and Operate a Well Permit
As the name implies, the Drill and Operate a Well Permit (aka, well drilling permit) authorizes
an operator to construct and operate a conventional or unconventional well. An
unconventional well site and well pad is typically constructed to accommodate multiple wells.

10 | P a g e
An operator is responsible to obtain an individual permit for each well that is constructed. A
Drill and Operate a Well Permit must be submitted to DEP for each additional well that is
intended to be drilled on the well pad or when an existing well is drilled deeper into a geologic
formation. The Oil and Gas Act requires DEP to render a permit decision within 45 calendar
days of receiving a complete application.
Distribution of Well Drilling Permits issued in Pennsylvania
In 2013, DEP issued a total of 4,617 well drilling permits to include both conventional and
unconventional wells in Pennsylvania. Of this amount, DEP issued 2,965 well drilling permits for
the construction of unconventional wells and 1,652 well drilling permits for the construction of
conventional wells.
The graph below shows the total number of conventional and unconventional well drilling
permits issued by DEP since 2008. As evidenced in this graph, the number of well drilling
permits issued by DEP has been trending downward since 2008. This downward trend is likely a
result of the industry’s reaction to the declining market price of natural gas during this same
timeframe as well as more efficient planning of well site locations by operators. As the market
price of natural gas began to rebound during 2013, there was a slight increase in the number of
permits received and issued by DEP as evidenced in the graph below.

equal in terms of the volume of available gas or the productivity of the wells that are
constructed.

Conventional Well Drilling Permits
The map below identifies the distribution, by county, of the 1,652 well drilling permits issued in
calendar year 2013 for the purpose of constructing conventional oil and gas wells.
As evidenced in the map, the majority of all well drilling permits for conventional well sites
were issued to operators in McKean, Warren and Venango counties since this area represents
the area commonly called the “oil patch” region of the state where Pennsylvania Grade crude
oil is most prevalent.

Distribution of Wells Drilled in PA
In 2013, operators drilled a total of 2,174 wells in Pennsylvania, including both conventional
and unconventional wells. Of this amount, 1,207 are unconventional wells and 967 are
conventional wells.
The actual numbers of unconventional and conventional wells that are drilled in Pennsylvania
vary from the numbers of well drilling permits that are issued by DEP. One reason for this is that
a well drilling permit is valid for a full year and can be extended if requested and approved by
DEP. An operator may commence drilling at any time during the period that the permit is in
effect. Depending on individual business practices, oil and gas operators may secure a well
drilling permit far in advance of commencing actual drilling operations. In some cases, an
operator may also determine that a site is not suitable for drilling. Due to these reasons, it is
common that the number of permits issued by DEP exceeds the number of wells drilled in any
given year.
Unconventional Wells Drilled

Well Plugging Program
It is estimated that more than 350,000 wells have been drilled in Pennsylvania, since the drilling
of oil and gas wells began over a century ago. Some wells that are drilled produce oil and gas
for many years while other wells are found to be “dry” and do not produce enough oil or gas to
be profitable. All wells that are drilled must be properly plugged or sealed to ensure that
communication between deeper brines and hydrocarbons and fresh groundwater sources does
not occur.
Although stringent requirements currently exist regarding the proper methods to plug wells,
this was not always the case. In fact, it was not until the passage of the Oil and Gas Act of 1984
that laws and regulations were created to ensure the safe plugging of orphaned and abandoned
wells. Prior to the passage of modern oil and gas laws, wells were sometimes plugged using
crude techniques such as driving a wood log into a well; while, in other cases, wells were simply
abandoned and never plugged. Abandoned well locations sometimes exist in unlikely places
such as residential communities, rural and farm communities, cemeteries, parking lots, under
buildings and in rare cases even in streams. Today, stringent oil and gas laws and regulations
have been promulgated and require wells to be properly plugged when they are no longer able
to serve their intended purpose. Also, operators are now required to post bonds with DEP to
ensure that wells are properly plugged at the end of their useful life.
DEP tracks all known orphaned and abandoned wells; however, many thousands of wells
continue to exist and their exact locations may not be known. Currently, there are over
8,300 orphaned and abandoned wells that are known to exist and are on record with DEP; and
many of them are located in the northwest and southwest regions of the state where much of
the early oil and gas exploration and production occurred. To date, the Well Plugging Program
has plugged a total of 2,948 wells.
Typically, the Well Plugging Program issues between 10 and 14 new plugging contracts each
year. The individual contracts vary in size and include between one to more than 100 wells. In

16 | P a g e
2013, the Well Plugging Program issued 14 new well plugging contracts that resulted in the
plugging of 38 individual wells located in the following counties: Washington, Allegheny,
McKean, Venango, Potter, Jefferson, Elk, Erie and Armstrong. Of that total, 14 were oil wells,
eight were gas wells and 16 were combined oil and gas wells. The general locations of the wells
that were plugged in 2013 are displayed on the map below.
When a responsible owner is known to exist or is identified, they are legally responsible to plug
a well when it is no longer capable of effectively producing oil or gas as intended or after it has
been abandoned. In this case, the operator is required to submit a “Notice of Intent by Well
Operator to Plug Wells” form to DEP prior to plugging the well. After well plugging is
completed, a “Certificate of Well Plugging” form must be submitted to DEP by the operator.
When orphaned and abandoned wells are discovered and no responsible owner exists, those
wells are placed on the department’s list of orphaned and abandoned wells. DEP inspects each
newly-discovered orphaned and abandoned well and ranks and subsequently prioritizes all
wells. Prioritization is based on health and safety criteria, environmental degradation and other
potential impacts. Wells that present a high risk to human health and safety and the
environment are plugged first. DEP inspectors routinely follow up to ensure that all wells are
plugged in accordance with DEP’s regulatory requirements.
Funding for the Orphan and Abandoned Well Plugging Program is derived from surcharges
established by Section 3271 of the 2012 Oil and Gas Act. Well plugging contracts are funded by
permit surcharges that are collected separately from, and in addition to, the well drilling permit
application fee. The orphan well surcharge is $100 for an oil well or $200 for a natural gas well.
A separate additional abandoned well surcharge of $50 applies to both oil and gas wells. The
Orphan Well Plugging Fund and the Abandoned Well Plugging Fund are dependent on the
Map depicting distribution of wells plugged in 2013

number of new drilling permits submitted to DEP by oil and gas operators. In addition to these
fees, the Oil and Gas Act of 2012 allocated funding to the Commonwealth Financing Authority
for the purpose of administering a program that includes the plugging of wells.
Streamlining the Permitting Process
e-Well Permitting
The e-Well Permit is intended to streamline the oil and gas permitting process and convert DEP
paper-based permits to a fully online system that will include an electronic application,
electronic review and electronic permit issuance.
DEP’s Oil and Gas Program is the first permit program within DEP that has been migrated to an
electronic permitting platform and will result in the elimination of paper-based permit
applications, reducing processing and physical storage space requirements. This new tool will
also increase efficiency, improve data integrity, and improve DEP’s ability to more quickly locate
records and provide timely responses to Right-to-Know requests.
The e-Well permit was developed in-house in partnership with DEP’s Bureau of Information
Technology. Oil and gas operators utilize a secure web interface where they can create and
electronically submit a well permit application with supporting documentation and associated
supplemental permits. DEP staff now has the ability to review and route permits more
efficiently while seamlessly interacting with the department’s enterprise-wide permitting and
compliance database called eFACTS (Environment Facility Application Compliance Tracking
System).
A user/operator workgroup was identified in 2012 to provide input to DEP regarding early
design concepts. DEP convened a user workgroup of select oil and gas operators to conduct
beta testing in late August 2013. The user workgroup provided comments to DEP regarding the
use of the proposed e-Well application. Feedback from the user workgroup as well as ongoing
internal testing assisted in the refinement of the e-Well application. The e-Well Permitting
System went live Nov. 13, 2013 for the initial user workgroup to use and will be opened to all
operators in 2014.
Natural Gas Compression Facilities General Permit (GP-5 permit)
On Feb. 2, 2013, DEP finalized revisions to a general plan approval and general operating permit
for natural gas-fired engines, dehydrators, storage tanks and other equipment at natural gas
compression and/or processing facilities (aka, GP-5 permit). Compressor stations help move gas
from well sites into transmission pipelines. This revised general permit establishes
requirements for best available technology, authorizes the construction, modification and
operation of these natural gas facilities. These minor sources typically are not subject to major
source permitting requirements including Title V and New Source Review of the federal Air

18 | P a g e
Pollution Control Act. The new GP-5 permit was developed after considering public comment
and includes significantly lower allowable emission limits than the previous general permit. The
GP-5 permit imposes emission limitations that are 75 to 90 percent more stringent than
previously permitted emission limits for natural gas-fired engines used at compressor stations.
In addition to more stringent emission limitations, this general permit includes municipal
notification, source testing, recordkeeping and reporting requirements. Operators of facilities
authorized to use the GP-5 permit must demonstrate that their facilities continue to be minor
sources as defined by the Clean Air Act which allows for operational flexibility. In addition to the
air quality benefits, this general permit has streamlined the overall air quality permitting
process.
Air Quality Permit Exemption Criteria Modification
Since 1996, oil and gas well sites in Pennsylvania had been granted blanket exemptions from
obtaining air quality plan approvals and operating permits (i.e., Exemption Criteria Category 38
for Gas Well Sites). Given the recent expansion in natural gas exploration and production
activities in Pennsylvania this blanket exemption has been modified and on Aug. 10, 2013, DEP
finalized new exemption criteria. These criteria require actions to be taken that are more
stringent than the EPA’s standards for new emission sources and result in emission levels of
minor significance. If an owner or operator is unwilling to or cannot meet these criteria, they
must seek an air quality plan approval for construction of the well site from DEP.
Permit Review Process and Permit Decision Guarantee
On July 24, 2012, Gov. Tom Corbett issued Executive Order 2012-11 that required DEP to
implement a “Permit Decision Guarantee” by immediately:
 Assessing how best to make timely permitting decisions;
 Providing clear expectations for applicants to improve the quality of applications;
 Establishing performance measures for review staff; and
 Developing, improving and encouraging electronic permitting tools.
Executive Order 2012-11 also rescinded a 1995 Executive Order that established the original
Money Back Guarantee for permits.
Over the course of 18 months, DEP reviewed existing permitting procedures and developed a
draft “Permit Review Process and Permit Decision Guarantee” policy that was published for
public comment. The "Permit Review Process and Permit Decision Guarantee" policy, replaces
the former Money Back Guarantee policy. A separate "Permit Coordination Policy" was also
developed to direct how the department will review projects that require multiple permits from
DEP.

19 | P a g e
The department reported on Nov. 1, 2013 as part of its 4th
Quarterly Report that 95 percent of
permits were issued within the guarantee timeframes according to the “Permit Review Process
and Permit Decision Guarantee.” It was further reported that the Office of Oil and Gas
Management increased its permitting efficiency by 13 percent when comparing the permitting
efficiency under the prior Money-Back Guarantee policy.
The Office of Oil and Gas Management remains committed to conducting permit reviews in a
manner that is protective of our environment; while also conducting such reviews in a timely
manner as directed by the “Permit Review Process and Permit Decision Guarantee.”
INSPECTIONS:
Another important responsibility of DEP’s Office of Oil and Gas Management is to conduct
rigorous inspections at oil and gas sites across the state. Inspections at well sites are necessary
to ensure that permit requirements are achieved at the actual well sites. In response to
enhanced oversight and in conjunction with the notification requirements contained in the
2012 Oil and Gas Act, the Office of Oil and Gas Management has significantly increased the
number of inspections conducted at conventional and unconventional well sites. Likewise, DEP
has increased the number of its inspectors since 2009 to its current level of more than
80 inspectors.
As depicted in the bar chart on the following page, the total number of all well inspections has
steadily increased from 2008 through 2012; and remained steady in 2013.
In 2008, the Office of Oil and Gas Management conducted 1,262 inspections of 377
unconventional wells. By 2012, the number of inspections increased to 12,680 inspections of
4,859 unconventional wells. This reflects an order of magnitude increase in the number of
inspections that were conducted during this five-year period. The inspection rates remained
steady during 2013 with 12,391 inspections of 5,559 unconventional wells.
In 2008, the Office of Oil and Gas Management conducted 10,058 inspections of 7,143
conventional wells. By 2012, the number of inspections increased to 11,762 inspections of
7,765 unconventional wells. The inspection rates remained steady during 2013 with 11,713
inspections of 7,808 conventional wells.
While the number of inspections of conventional wells has increased over time since 2008, the
significant increase in the number of inspections of unconventional wells, coupled with
inspections of oil and gas well pad sites and administrative inspections, has resulted in a
significant increasing trend of total oil and gas inspections over the past five years.

20 | P a g e
COMPLIANCE AND ENFORCEMENT:
The department has increased its efforts over the past several years to ensure improved
regional consistency and continuous improvement in its compliance and enforcement programs
that are administered by DEP’s district oil and gas offices.
It should also be noted that the number of violations as a result of DEP’s inspection efforts has
been steadily decreasing over this same time period. The record suggests that DEP’s compliance
initiatives and outreach to unconventional operators are working as compliance rates are
improving.
Compliance Trends
The following graph indicates that the number of violations observed at unconventional oil and
gas well sites has been decreasing throughout Pennsylvania since 2010. From 2010 until 2013,
the number of violations at unconventional well sites decreased from 1,281 to 512. This
represents a reduction of more than one half the number of violations during this four-year
time frame. The number of enforcement actions has proportionally increased by percentage
during this same time period. This suggests that although overall compliance by unconventional
oil and gas operators has been improving, DEP has continued to vigorously pursue enforcement
actions as warranted.

STRAY GAS INVESTIGATIONS:
One of the most important issues associated with oil and gas exploration and development
pertains to the effective engineering and construction of oil and gas wells. If wells are not
constructed or operated properly, there is a potential risk for natural gas to escape from the
well bore and into subsurface geologic strata or groundwater sources. If this happens, it is
called “stray gas” migration and the responsible operator is required by law to correct or
mitigate the situation.
Through efficient communication and collaboration with district oil and gas operations staff,
the Office of Oil and Gas Management has created a database of stray gas case investigations.
The information compiled dates back to 1987 and allows for critical data trend analysis and
some level of forensic work aimed at identifying causes and solutions in the rare instances
when operating oil and gas wells in the state have been found to not provide adequate
protection of water resources. This invaluable summary of information helps to direct policy
decisions and inform the development of focused new regulations.
Following is a graph that identifies the number of stray gas investigations conducted by DEP
from 2008 through 2013. For comparison sake, the graph also includes the investigations that
were conducted by each district oil and gas office.

Stray gas investigations are primarily driven by complaints from individuals who believe their
property may have been impacted by gas migrating into a water well or surface water body
such as a pond, stream or wetland. Since natural gas is colorless and odorless, the most
common indicators suggesting potential gas migration are the appearance of many tiny
“bubbles” (i.e., effervescence) in tap water drawn from the supply or off-gassing from a water
well or surface water body; or the sound of “knocking” in a water well that results when
infiltrating gas disturbs the well pump. In some cases, an initial review of the complaint may
reveal that the condition is, in fact, not related to gas migration. Such cases are tracked and
responded to via DEP’s Complaint Tracking System and are not cataloged as gas migration
events. In other cases, the investigation might require a lengthy series of site visits and multiple
rounds of lab analyses to reach a determination concerning the alleged gas migration event. It
could take many months or even years to reach a final determination.
After a thorough inspection, review of all laboratory analyses, an assessment of construction
and integrity data and a geological assessment, DEP renders a determination regarding the
event. The determination may result in either of the following findings:
Positive Determination: The migration of gas is confirmed and is the result of
hydrocarbon exploration and production activities. These findings are either
documented through issuance of an official determination letter to the complainant, or,
if no formal complaint is filed with DEP, the department documents which water

supplies or residences have been impacted as a result of hydrocarbon exploration and
production activities and responds as appropriate.
Negative Determination: The presence of gas is either confirmed, but cannot be
positively attributed to hydrocarbon exploration and production activities or, in certain
cases, no gas is found.
There are generally two classifications of natural gas – “biogenic gas” and “thermogenic
gas”. Biogenic gas is formed by microbial decomposition of organic matter nearer to the
earth’s surface; whereas, thermogenic gas is formed when organic matter in
sedimentary rock is subjected to heat and pressure deep under the earth’s surface. In
some cases, Negative Determinations result when it is found that the type of gas
detected is “biogenic” rather than “thermogenic” gas that is targeted during natural gas
exploration and production activities. However, both gas types are found to exist
naturally in portions of Pennsylvania’s fresh groundwater system.
The following bar chart identifies the number of confirmed Positive Determinations from 2008
through 2013 for gas migration cases investigated by DEP. If a stray gas investigation does not
result in a confirmed Positive Determination, then it is not included in this bar graph. If a stray
gas investigation extends from one calendar year into a future calendar year, the confirmed
positive determination is reported in the year in which the investigation was initiated. DEP is
currently conducting several investigations that are expected to be completed during 2014.
The Pennsylvania Oil and Gas Regulation at 25 Pa. Code, Chapter 78, Subchapter D provides
specific requirements for the construction of oil and gas wells including, but not limited to,
casing and cementing practices. It also details requirements that operators must fulfill when a
potential gas migration incident has occurred. The department updated these subsurface

activities regulations to strengthen well construction practices that are required of operators
and place many of the responsibilities of investigating stray gas incidents on the oil and gas
industry. The revised rulemaking went into effect on Feb. 5, 2011. The department intends to
further strengthen these subsurface activity regulations through a subsequent rulemaking
package that it will initiate in 2014.
The bar chart above identifies the number of drinking water supplies impacted by confirmed
gas migration events. It is not uncommon for a single confirmed gas migration to affect multiple
water sources.
The Oil and Gas Act of 2012 presumes that an operator of an unconventional well is responsible
for pollution of a water supply when the source is located within 2,500 feet of the
unconventional well and when the pollution occurred within 12 months of the drilling,
stimulation or completion of the unconventional well. Unless, the operator can successfully
demonstrate that the pollution was not caused by its actions based on specific statutory
defenses, the operator must restore or replace the affected water supply with an alternate
water source.
REGULATORY AND POLICY DEVELOPMENT:
When the 2012 Oil and Gas Act was signed by Gov. Corbett on Feb. 14, 2012, it represented the
first major overhaul of the commonwealth’s Oil and Gas Act in 28 years. The act became
effective within 60 days of passage, which required the Office of Oil and Gas Management to
prepare new forms, standard operating procedures, guidance documents, policy statements
and Frequently-Asked-Question responses. DEP provided training to the regulated community

and the public on the new documents. The department successfully met that challenge by
working to define specific planning and containment requirements of the 2012 Oil and Gas Act
and conducting a series of outreach webinars to inform and train the public and regulated
community on the new requirements.
Regulatory Revisions for Surface Activities
DEP’s Oil and Gas program has devoted more than two years to developing a proposed
rulemaking to amend the existing oil and gas regulations (25 Pa. Code, Chapter 78,
Subchapter C) to specifically address surface-related activities at well sites in Pennsylvania. In
particular, these regulations will address the requirements for pits, impoundments, temporary
site containment, spill reporting and cleanup, site restoration, pipelines, horizontal directional
drilling, water management plans and the road spreading of brine from conventional well sites.
This rulemaking also serves to codify environmental provisions mandated by the 2012 Oil and
Gas Act.
A draft proposed rulemaking was presented to the Oil and Gas Technical Advisory Board on five
separate occasions. The Oil and Gas Program also received input from multiple stakeholder
groups including oil and gas operators/associations, the environmental community,
municipalities and the public.
On Aug. 27, 2013 this proposed rulemaking was presented to the Environmental Quality Board
(EQB) for consideration and was approved for publication and a 60-day public comment period.
The public comment period opened on Dec. 14, 2013 and was initially scheduled to close on
Feb. 12, 2014. The EQB initially announced that it would host seven public hearings throughout
each of the regions of Pennsylvania; however, to promote a greater level of public
participation, the EQB and DEP in an unprecedented manner extended the public comment
period for 30 additional days to close on March 14, 2014 and added two more public hearings.
In addition to the public hearings, the department hosted two webinars to brief the public on
the key provisions of the proposed rulemaking and inform the public how comments can be
submitted to the department.
The department will consider all comments received as it proceeds with the development of
this final rulemaking. It is anticipated that a proposed final rulemaking will be presented to the
Oil and Gas Technical Advisory Board in 2014.
Regulatory Revisions for Unconventional Well Permit Fees
As required by the Oil and Gas regulations, DEP prepared a three-year report on its fee
structure and developed a proposed rulemaking to address the disparity between program
income and program costs. This rulemaking proposes to amend the existing oil and gas
regulations (25 Pa. Code, Chapter 78, Subchapter B) to modify the unconventional natural gas

26 | P a g e
well permit fee structure from a sliding fee schedule based on well bore length to a fixed fee of
$5,000 for horizontal unconventional wells and $4,200 for vertical unconventional wells. The
current permit structure for conventional wells remains unchanged.
The proposed rulemaking was presented to the Oil and Gas Technical Advisory Board at its April
23, 2013 meeting. DEP presented the proposed rulemaking package to the EQB on July 16, 2013
and the board voted unanimously to proceed with publication for a 30-day public comment
period. The proposed rulemaking was published in the Pennsylvania Bulletin on Sept. 14, 2013
and closed on Oct. 15, 2013. The department received comments from six commentators and
prepared a Comment and Response Document. On Jan. 21, 2014, EQB adopted the final
rulemaking and DEP anticipates this rulemaking to become effective mid-2014.
Emergency Response at Well Sites
On Jan. 26, 2013, the EQB adopted a final-form rulemaking under the authority of Act 9 of
2012, that required DEP and the Pennsylvania Emergency Management Agency to adopt
emergency regulations directing the operators of all unconventional wells in Pennsylvania to
take certain actions for emergency response. The requirements of the regulation include
development and submission of emergency response plans, obtaining and providing 911
addresses and GPS coordinates for access roads to unconventional well sites and posting of
standard signage at the entrance to access roads to those sites. These regulations implement
several recommendations of the Governor’s Marcellus Shale Advisory Commission.
Addressing Spills and Releases at Oil and Gas Well Sites - Final Guidance
DEP developed a draft technical guidance document titled “Addressing Spills and Releases from
Oil & Gas Wells and Related Operations.” This policy was developed to facilitate a consistent
and uniform general response by those working in and for the oil and gas industry to respond to
spills and releases related to oil and gas well operations. The policy addresses expectations for
1) spill prevention and response planning, 2) notification to DEP in the event of a spill or
release, 3) remediation of the spill or release to meet a standard established by the Land
Recycling and Environmental Remediation Standards Act and the required administrative
process or alternate process, and 4) restoration and re-vegetation of areas impacted by spills or
releases (particularly chlorides). The department discussed the draft guidance with the Oil and
Gas Technical Advisory Board in October 2011 and February 2012.
Notice of the draft technical guidance was published in the Pennsylvania Bulletin on April 14,
2012, with a 30-day public comment period. DEP received approximately 67 unique comments
from 12 individuals, companies, organizations and associations. The department considered
these comments, prepared a Comment-and-Response document and made several changes to
the policy. In addition, the draft final guidance parallels section 78.66 of the draft proposed
Surface Activities rulemaking at 25 Pa. Code, Chapter 78, Subchapter C. The final guidance was

27 | P a g e
discussed at the Feb. 20, 2013 TAB meeting and the department published notice of this final
guidance document in the Pennsylvania Bulletin on Sept. 21, 2013.
INNOVATIONS:
Mechanical Integrity Assessments (Quarterly Inspections)
When an operator constructs a well to deliver oil and gas from deep beneath the ground to the
surface, it is critical that the well be constructed in a manner that prevents communication
between the well bore and shallower sub-surface geologic strata. A properly constructed well
also helps to prevent the migration of oil and gas into groundwater sources that supply drinking
water wells.
To ensure well construction materials are functioning as intended over the life of the well,
Pennsylvania’s Oil and Gas Regulation (25 Pa. Code, Chapter 78, Section 78.88) includes
requirements for regular inspections of the well components accessible at the surface.
Specifically, operators are required to conduct quarterly inspections to ensure all operating
wells are in compliance with well construction and operating standards described in the
regulations. If wells are identified as not in compliance, the responsible operator is required to
notify DEP and take corrective actions to repair or replace defective equipment or mitigate any
excess pressure on the surface casing strings through which gas is being produced.
During 2013, the DEP’s Office of Oil and Gas Management developed a Mechanical Integrity
Assessment inspection form and instructions along with supporting guidance documents and
training videos. These tools are designed to facilitate the collection of electronic well integrity
data during the quarterly monitoring activities specified in 25 Pa. Code, Chapter 78, Section
78.88. Additionally, the Office of Oil and Gas Management conducted five industry training
sessions throughout the state in 2013. These events were well attended by oil and gas
operators, with nearly 300 individuals registered.
The quarterly inspection program began in the fourth quarter of 2013. The first annual
inspection report, consisting of quarterly inspection data for the 2014 calendar year, must be
submitted to the department by February 2015.
Oil and Gas GIS Map
On Dec. 19, 2013 DEP announced the release of a new online Oil and Gas Well Mapping Tool
that provides convenient access to statewide well data. This tool serves as a one-stop-shop in
making information about permitted wells available to the public on a graphical platform. This
is the first step in a process of linking all associated information regarding individual oil and gas
wells such as well records, completion reports and well plat information in a user-friendly GIS
format. This tool is available to the public on the DEP website at www.dep.state.pa.us (Select
“Oil and Gas”, then choose “Oil and Gas Reports”).

28 | P a g e
Online Public Comment System
DEP’s Bureau of Information Technology developed an online public comment tool to more
efficiently receive all public comments and effectively prepare responses to those comments.
Previously, public comments were accepted by way of e-mail and in hardcopy through the
U.S. Postal Service. This tool offers commentators an additional option of submitting their
comments electronically so that DEP can more effectively assemble, track and respond to public
comments. This tool was launched on Dec. 14, 2013 to accept comments received during the
90-day public comment period for the Chapter 78, Subchapter C (oil and gas surface activities)
proposed rulemaking. The Online Public Comment System will be used by DEP to accept public
comments for other future rulemakings.
Partnerships and Research
U.S. Geological Survey
Working with the United States Geological Survey (USGS), the Pennsylvania Geological Survey,
and conventional operators in northwestern Pennsylvania, DEP’s Office of Oil and Gas
Management staff have helped coordinate agreements that will grant the USGS and the
Pennsylvania Geological Survey access to conventional well sites in order to conduct borehole
geophysical logging. These logs will help identify the base of fresh groundwater and shallow
gas-bearing zones in portions of the state where historical oil and gas drilling has been prolific,
yet subsurface data remain sparse. The efforts will contribute to a greater understanding of
local hydrogeologic systems among researchers and interested members of the public while
helping to inform oil and gas operators during the development of casing and cementing plans.
Pennsylvania Geological Survey
DEP’s Office of Oil and Gas Management staff collaborated with DCNR’s Pennsylvania
Geological Survey to co-author an open file water resources report that reviews the
groundwater and petroleum resources of Sullivan County. Published in 2013, this report
discusses in detail the baseline water quality and hydrogeology within the county. It also
examines historical oil and gas development throughout a broader region of northeastern
Pennsylvania while discussing many aspects of stray gas migration.
WHAT’S NEW FOR 2014?
Comprehensive Oil and Gas Development Radiation Study
Generation of Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) in
solid waste generated by the oil and gas industry has increased in Pennsylvania over the past
several years due, in part, to the expansion of unconventional natural gas production.
In January 2013, DEP announced it would undertake a study to assess levels of naturally
occurring radioactivity in the by-products associated with oil and natural gas development. The

29 | P a g e
purpose of this study is to develop a final report with findings that are scientifically-based to
determine whether any further actions are warranted by DEP to ensure the continued
protection of the public and Pennsylvania’s environment.
On April 4, 2013, DEP released a detailed project scope and sampling and quality assurance
plans for this comprehensive study. This represents the most comprehensive study of its kind in
Pennsylvania and perhaps the nation. DEP is managing and funding the study which is expected
to be completed and published in 2014.
Mechanical Integrity Assessments (Defective Cement)
In addition to well construction standards, Pennsylvania’s oil and gas regulations also require
that an operator report defective wells (i.e., defective, insufficient or improperly cemented
casing) to DEP within 24 hours of discovery and correct the defect or submit a corrective action
plan to DEP within 30 days describing how it intends to address the defect. Wells that are
inspected and are found to exhibit defective cement, usually characterized by the presence of
gas flowing through cement, must be remediated or evaluated to ensure continuing integrity.
DEP has been in discussions with operators about what specifically constitutes “defective
cement” and the manner in which to most appropriately repair, replace or mitigate the
situation to the satisfaction of the department. A casing and cementing practices workgroup
was formed that includes members of DEP’s Office of Oil and Gas Management, the Oil and Gas
Technical Advisory Board and various oil and gas operators. Detailed flow charts and draft
guidance have been developed and presented to the workgroup for review and comment and
now serves as an interim corrective action plan that operators may choose to follow to address
any occurrences of defective cement.
In early 2013, DEP’s Oil and Gas Program developed a draft form for the voluntary submission
of well integrity data to assist with defining conditions that constitute “defective cement.”
During 2014, the Office of Oil and Gas Management intends to clearly define “defective
cement” and finalize the process for efficiently mitigating its occurrence.
Regulatory Revisions for Subsurface Activities
The Oil and Gas Division of Well Plugging and Subsurface Activities intends to advance a draft
proposed rulemaking during 2014 to update Subchapter D of 25 Pa. Code, Chapter 78.
The rulemaking will include revisions to Subchapter D that regulate the drilling, casing,
cementing, completion, operation, production and plugging of wells in Pennsylvania as well as
other subsurface activities associated with oil and gas exploration and development.
Specifically, the regulatory amendments will include revisions to well plugging procedures as
well as venting and alternative methods.

30 | P a g e
Whereas the Chapter 78, Subchapter C proposed rulemaking pertains mainly to aspects of
drilling related to “surface” activities, the Subchapter D proposed rulemaking will focus on
aspects of drilling related to “subsurface” activities.
This rulemaking will also implement relevant environmental provisions mandated by the 2012
Oil and Gas Act.
Long-Term Air Quality Monitoring Study
DEP is currently conducting a long-term study to measure air quality at sites that could
potentially be impacted by nearby natural gas compressors and processing stations. The
monitoring sites were selected near permanent facilities that have been shown to be a source
of methane, nitrogen oxides, carbon monoxide and hazardous air pollutant emissions. The
samples collected during the study are subjected to rigorous quality-assurance and data
validation criteria. A final report is expected to be released in 2014.
DEP previously conducted three short-term sampling studies in various drilling regions of the
state and detected no levels of any pollutant that would violate federal ambient air quality
standards or would be expected to cause air-related health issues.
Legacy Oil and Gas Map Initiative
DEP is developing a “Legacy Oil and Gas Map” tool that will overlay and display all available
historical oil and gas maps utilizing a web-based GIS platform. DEP has already developed a
similar tool to display legacy mining maps and this represents the next step in making map
information available to the public and the regulated community.
DEP has assembled an inventory of about 2,000 maps and will be advancing this initiative in
order to make the data on these maps accessible during 2014. This is expected to be a multi-
year initiative and as additional maps are acquired they will be added to the Legacy Oil and Gas
Map tool.
Pipeline Safety and Inspections
DEP inspects well sites and natural gas gathering pipelines; however, rugged terrain associated
with linear pipeline development in remote mountainous areas of Pennsylvania often presents
significant challenges in reaching long stretches of gathering pipelines for inspection purposes.
In 2013, the Office of Oil and Gas Management initiated a pilot project using department-
owned all-terrain vehicles to access remote natural gas gathering pipeline operations to
conduct inspections. This project was designed to monitor and inspect pipelines prior to, during
and after construction operations to assess compliance with the Department’s Erosion and
Sediment Control General Permits and other environmental laws and regulations.

31 | P a g e
The initial pilot project was successful; therefore, DEP plans to expand this initiative in 2014 to
target additional pipeline locations. The department also intends to continue existing inter-
agency communication, cooperation and partnering with the Pennsylvania Fish and Boat
Commission, Pennsylvania Game Commission and PUC during the coming year.
In addition, DEP intends to partner with PUC in 2014 to form a separate “Joint Pipeline Working
Group” to examine and evaluate the current safety conditions and practices associated with the
construction of gas pipelines in Pennsylvania.
A CULTURE OF CONTINUOUS IMPROVEMENT:
DEP is never satisfied to rest on past achievements; rather it continually seeks opportunities to
improve its programs, practices and policies. DEP’s culture of continuous improvement is
clearly reflected in how it has responded to the wide-spread interest regarding the
development of unconventional natural gas resources in Pennsylvania.
As unconventional drilling has increased over the past several years, DEP has taken proactive
measures to strengthen and enhance its regulatory framework to ensure responsible oil and
gas development that is protective of Pennsylvania’s citizens and environment. DEP expects
world-class performance from all oil and gas operators that engage in business in the state, and
DEP holds itself accountable to these same standards.
This annual report has shared specific examples of how DEP and the Office of Oil and Gas
Management has developed and implemented new and improved methods of regulating the oil
and gas industry in Pennsylvania. Our work is not done. DEP’s Office of Oil and Gas
Management embraces the challenges it is faced with to advance the mission of the
department in 2014.
