Federal Pollution Control Laws: How Are They Enforced?

Summary
As a result of enforcement actions and settlements for noncompliance with federal pollution
control requirements, the U.S. Environmental Protection Agency (EPA) reported that, during
FY2012, regulated entities committed to invest an estimated $9.0 billion for judicially mandated
pollution controls and cleanup, and for implementing mutually agreed upon (supplemental)
environmentally beneficial projects. EPA estimated that these efforts achieved commitments to
reduce, treat, or eliminate 2.2 billion pounds of pollutants in the environment, primarily from air
and water. EPA also assessed more than $208.0 million in civil penalties (administrative and
judicial) and $44.0 million in criminal fines and restitution during FY2012. Noncompliance with
federal pollution control laws remains a continuing concern. The overall effectiveness of the
enforcement organizational framework, the balance between state autonomy and federal
oversight, and the adequacy of funding are long-standing congressional concerns.
This report provides an overview of the statutory framework, key players, infrastructure,
resources, tools, and operations associated with enforcement and compliance of the major
pollution control laws and regulations administered by EPA. It also outlines the roles of federal
(including regional offices) and state regulators, as well as the regulated community.
Understanding the many facets of how all federal pollution control laws are enforced, and the
responsible parties involved, can be challenging. Enforcement of the considerable body of these
laws involves a complex framework and organizational setting.
The array of enforcement/compliance tools employed to achieve and maintain compliance
includes monitoring, investigation, administrative and judicial (civil and criminal) actions and
penalties, and compliance assistance and incentive approaches. Most compliance violations are
resolved administratively by the states and EPA. EPA concluded 1,780 final administrative
penalty orders in FY2012. Civil judicial actions, which may be filed by states or EPA, are the
next most frequent enforcement action. EPA may refer civil cases to the U.S. Department of
Justice (DOJ), referring 215 civil cases in FY2012. The U.S. Attorney General’s Office and
DOJ’s Environmental Crimes Section, or the state attorneys general, in coordination with EPA
criminal investigators and general counsel, may prosecute criminal violations against individuals
or entities who knowingly disregard environmental laws or are criminally negligent.
Federal appropriations for environmental enforcement and compliance activities have remained
relatively constant in recent fiscal years. Some contend that overall funding for enforcement
activities has not kept pace with inflation or with the increasingly complex federal pollution
control requirements. Congress appropriated $583.4 million for enforcement activities for
FY2012, a decrease below the $593.5 million enacted for FY2011 and the $596.7 million enacted
for FY2010, but an increase above the $568.9 million enacted for FY2009 and $553.5 million for
FY2008. The President’s FY2013 and FY2014 budget requests included $615.9 million and
$625.0 million, respectively, for EPA enforcement activities. Division F of P.L. 113-6, the
Consolidated and Further Continuing Appropriations Act, 2013, enacted March 26, 2013,
appropriated funding for the full fiscal year through September 30, 2013, for seven regular
appropriations acts, including Interior, Environment, and Related Agencies, which funds EPA.
Although the agency submitted its FY2013 Operating Plan to the House and Senate
Appropriations Committees on May 14, 2013, detailed allocations of EPA’s FY2013 enacted
funding for enforcement program activities across the agency’s multiple appropriations accounts
were not readily available at the time this report was updated.

Federal Pollution Control Laws: How Are They Enforced?

Introduction
Congress has enacted laws requiring individuals and facilities to take measures to protect
environmental quality and public health by limiting potentially harmful emissions and discharges,
and remediating damage. Enforcement of federal pollution control laws in the United States
occurs within a highly diverse, complex, and dynamic statutory framework and organizational
setting. Multiple statutes address a number of environmental pollution issues, such as those
associated with air emissions, water discharges, hazardous wastes, and toxic substances in
commerce. Regulators and citizens take action to enforce regulatory requirements in a variety of
ways to bring violators into compliance, to deter sources from violating the requirements, or to
clean up contamination (which may have occurred prior to passage of the statutes).
Implementation and enforcement provisions vary substantially from statute to statute, and are
often driven by specific circumstances associated with a particular pollution concern. Given these
many factors, it is difficult to generalize about environmental enforcement.
This report focuses on enforcement of federal environmental pollution control requirements under
the Clean Air Act (CAA); the Clean Water Act (CWA); the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA or Superfund); and other statutes for
which EPA is the primary federal implementing agency.1 The report provides a brief synopsis of
the statutory framework that serves as the basis for pollution control enforcement, including an
overview of the key players responsible for correcting violations and maintaining compliance.
Implementation and enforcement of pollution control laws are interdependent and carried out by a
wide range of actors including federal, state, tribal, and local governments; the regulated entities
themselves; the courts; interest groups; and the general public. Figure 1, below, presents the array
of local, state, tribal, and federal entities that constitutes the environmental pollution control
enforcement/compliance framework and organizational setting.

Federal Pollution Control Laws: How Are They Enforced?

A diverse set of regulatory approaches and enforcement tools is applied to a sizeable universe of
regulated entities by these multiple regulating authorities to ensure compliance. A general
discussion of enforcement monitoring and response tools is included in this report, followed by a
summary of recent fiscal year federal funding levels for enforcement activities. Discussion of
available enforcement data sources, as well as tables illustrating examples of trends in
enforcement activities, is presented in the two appendixes.
While this report touches on many aspects of environmental enforcement, it does not describe
every aspect and statute in detail. Rather, the report is intended to provide a broad perspective of
environmental enforcement by highlighting key elements, and a general context for the range of
related issues frequently debated. Information included in this report is derived from a variety of
sources. These sources, including relevant subject-matter CRS reports providing in-depth
discussion of specific topics and laws, are referenced throughout.
Several themes reflecting congressional concerns over time since EPA was established in 1970
are reflected throughout the major sections of this report. Congress has conducted oversight,
primarily in the form of hearings, on various aspects of the organizational infrastructure and
operations designed to enforce pollution control statutes.2 These aspects of enforcement have also
been the topic of investigations by the Government Accountability Office (GAO)3 and EPA’s
Office of Inspector General (EPA-OIG).4 The federal government’s oversight of and coordination
with states in implementing and enforcing federal pollution control laws have been of particular
interest to Congress.5 The following sections briefly discuss some of the key issue areas.

Federal Pollution Control Laws: How Are They Enforced?

Federal and State Government Interaction
Since many, but not all, of the federal pollution control statutes authorize a substantial role for
states, state autonomy versus the extent of federal oversight is often at the center of debate with
regard to environmental enforcement. Not unexpectedly, given the “cooperative federalism”6 that
is often used to characterize the federal, state, and tribal governments in the joint implementation
and enforcement of pollution control requirements, relationships and interactions among these
key enforcement players often have been less than harmonious.
Disagreements involving environmental priorities and strategic approaches, and balancing the
relative roles of compliance assistance with enforcement, contribute to the complexity and
friction that come with enforcing national pollution control laws. Other contributing factors
include the increasing number of statutory and related regulatory pollution control requirements
(some with conflicting mandates) and the adequacy of the resources available for their
implementation.
The effects of variability among statutes, coupled with variability in federal and state
interpretations and regulations, are often central to the debate. Some argue that this variability
leads to too much inconsistency in enforcement actions from state to state, region to region, or
between federal versus state actions. Others counter that this represents the flexibility and
discretion intended by the statutes to address specific circumstances and pollution problems.
A July 2007 GAO report found that progress had been made regarding federal oversight of state
environmental enforcement programs, and that there had been improvements with regard to
cooperative federal-state planning and priority setting. However, the GAO concluded that a
greater effort was needed to achieve more consistency and effectiveness, and that these issues
continue to need improvements.7 In a December 2011 report, the EPA OIG found that although
“OECA had made efforts to improve state performance and consistency … state performance
remains inconsistent across the country, providing unequal environmental benefits to the public
and an unlevel playing field for regulated industries.”8

Federal Funding and Staffing for Enforcement Activities
The level of federal funding allocated to states and tribes to support effective enforcement of
federal pollution control laws has also been a long-standing congressional concern.9 In March
2012, Environmental Council of the States (ECOS) reported concerns among state environmental
agencies with regard to the extent of reductions in federal funding for state environmental
protection activities.10 In a 2008 study, ECOS11 reported that during 2005-2008 states expected
spending to implement federal environmental laws to double while federal appropriations
declined.12 Subsequently, ECOS reported that although federal funding for enforcement allocated
to states increased marginally from FY2009 to FY2010, overall, reductions in state budget
revenue are impacting their ability to maintain viable environmental enforcement programs.13 In
2007, GAO reported that, although funding overall for enforcement activities had increased
somewhat, it generally had not kept pace with the increasing number of mandates and regulations,
or with inflation.14
The federal enforcement funding and personnel, primarily within EPA and the Department of
Justice (DOJ), to ensure effective enforcement of environmental statutes has also been a concern
of both appropriations and authorizing committees in Congress. Recently, in addition to funding
priorities among the various EPA programs and activities (including enforcement), several
promulgated and pending EPA regulatory actions15 were central to debates on EPA’s FY2011,
FY2012, and FY201316 appropriations. During the previous fiscal years’ appropriations

16 Appropriations committees and several authorizing committees held hearings to consider the President’s FY2013
budget request for EPA during the 112th Congress, but no bill to fund Interior, Environment, and Related Agencies
(which includes EPA) for FY2013 was enacted prior to the start of FY2013. Although not enacted, Title II of H.R.
6091, the Interior, Environment, and Related Agencies Act, 2013, as reported by the House Committee on
Appropriations on July 10, 2012, included several directive provisions restricting certain EPA actions. A draft bill
released on September 25, 2012, by the bipartisan leadership of the Senate Appropriations Subcommittee on Interior,
Environment, and Related Agencies did not include similar provisions. EPA and several other federal departments and
agencies are operating under the Consolidated and Further Continuing Appropriations Act, 2013 (Division F of P.L.
113-6), enacted March 26, 2013, which generally did not include the directive provision proposed in the House
committee bill. See CRS Report R42520, Environmental Protection Agency (EPA) Appropriations for FY2013: Debate

deliberations, several provisions were proposed, and a subset adopted, that restricted the use of
funding for the development, implementation, and enforcement of certain regulatory actions that
cut across the various environmental pollution control statutes’ programs and initiatives.17
Regulatory actions under the Clean Air Act, in particular EPA controls on emissions of
greenhouse gases, as well as efforts to address conventional pollutants from a number of
industries, received much of the attention during the FY2011 and FY2012 appropriations debate.
Several regulatory actions under the Clean Water Act, Safe Drinking Water Act, and Resource
Conservation and Recovery Act (RCRA) also received some attention. Some Members expressed
concerns related to these actions during hearings of EPA’s FY2013 appropriations, and
authorizing committees continued to address EPA regulatory actions through hearings and
consideration of legislation during the 112th Congress.
Other Enforcement Issues
Many other aspects of pollution control enforcement have been the subject of debate, and
highlighted in congressional hearings and legislation. Some additional areas of continued interest
include
• whether there is a need for increased compliance monitoring and reporting by
regulated entities;
• impacts of environmental enforcement and associated penalties/fines on federal
facilities’ budgets (most notably the Department of Defense, or DOD, and
Department of Energy, or DOE);
• how best to measure the success and effectiveness of enforcement (e.g., using
indicators such as quantified health and environmental benefits versus the
number of actions or dollar value of penalties);
• whether penalties are strong enough to serve as a deterrent and maintain a level
economic playing field, or too harsh and thus causing undue economic hardship;
• how to balance punishment and deterrence through litigation with compliance
assistance, incentive approaches, self-auditing or correction, and voluntary
compliance;
• the effect of pollutant trading programs on enforcement; and
• the level of funding required to effectively achieve desired benefits of
enforcement.
These issues result from disparate values and perspectives among stakeholders, but also from the
factors that are the focus of this report: the statutory framework, those who work within this

framework, and the tools and approaches that have been adopted for achieving compliance with
pollution control laws.
The discussion below, beginning with identification of the principal statutes and key players,
followed by an overview of integrated systems of administrative and judicial enforcement,
compliance assistance, and incentive tools, is intended to provide a macro-perspective of
environmental enforcement infrastructure and operations.
Statutory Framework for Enforcement of
Pollution Control Laws and Key Players

As Congress has enacted a number of environmental laws over time, as well as major
amendments to these statutes, responsibilities of both the regulators and the regulated community
have grown. Organizational structures of regulatory agencies have evolved in response to their
expanding enforcement obligations. Regulators also must adapt to an evolving, integrated system
of administrative and judicial enforcement, compliance assistance, and incentive tools (see
discussion under “Enforcement Response and Compliance Tools,” later in this report).
Statutory Framework
The 11 laws listed in Table 1 generally form the legal basis for the establishment and
enforcement of federal pollution control requirements intended to protect human health and the
environment.

Federal Pollution Control Laws: How Are They Enforced?

The discussion in this report focuses on these federal environmental laws for which the U.S.
Environmental Protection Agency (EPA) is the primary federal implementing agency. Since EPA
was created in 1970, Congress has legislated a considerable body of law and associated programs
to protect human health and the environment from harm caused by pollution. Those federal
statutes, intended to address a wide range of environmental issues, authorize a number of actions
to enforce statutory and regulatory requirements.
Enforcement of this diverse set of statutes is complicated by the range of requirements, which
differ based on the specific environmental problem, the environmental media (e.g., air, water,
land) affected, the scientific basis and understanding of public risks, the source(s) of the
pollutants, and the availability of control technologies. Regulatory requirements range from
health and ecologically based numeric standards, or technology-based performance requirements,
to facility-level emission and discharge permit limits. Several of the pollution control laws require
regulated entities to obtain permits, which typically specify or prohibit certain activities, or
delineate allowable levels of pollutant discharges. These permits are often the principal basis for
monitoring, demonstrating, and enforcing compliance. In recent years, an increasing number of
administrative initiatives have favored incentive-based regulatory approaches, such as trading of
permitted emissions, which can affect the applicability of traditional enforcement approaches.
Regulating authorities establish enforcement response and compliance assistance programs to
address the enforcement provisions of particular federal pollution control statutes. These
environmental statutes typically authorize administrative, civil judicial, and criminal enforcement
actions for violations of statutory provisions. For example, Section 309 of the CWA, Section 113
of the CAA, and Section 1414 of the Safe Drinking Water Act (SDWA) cover enforcement
provisions.18 As provisions for specific actions vary from statute to statute, each EPA regulatory
program office establishes detailed criteria for determining what sanctions are preferable (and
authorized) in response to a given violation. The statutes often provide a level of discretion to
regulators for addressing specific circumstances surrounding certain environmental problems or
violations of national requirements.
Enforcement of the many provisions of the major environmental laws across a vast and diverse
regulated community involves a complex coordinated process between federal (primarily EPA
and DOJ), state, tribal, and local governments. Congress provided authority to states for
implementing and enforcing many aspects of the federal statutory requirements. Citizens also
play a role in ensuring that entities comply with environmental requirements, by reporting
violations or filing citizen lawsuits, which are authorized under almost all pollution control laws.
The following discussion highlights the roles of these key players.
Key Players in Environmental Enforcement and Compliance
U.S. Environmental Protection Agency
Primarily through its program offices (e.g., air, water, solid waste), EPA promulgates national
regulations and standards.19 Other federal agencies (e.g., the Department of the Interior, Army
Corp of Engineers) and states, tribes, various stakeholder groups, and citizens may contribute

input to EPA at various stages of regulatory development (including required public comment).
(States may also establish their own laws based on the national requirements; see the discussion
later in the “States and “Delegated Authority” section of this report.) EPA (and states) inform the
regulated community of their responsibilities and administer permitting, monitoring, and
reporting requirements. EPA also provides technical and compliance assistance, and employs a
variety of administrative and judicial enforcement tools as authorized by the major environmental
laws it administers, as well as incentive approaches, to promote and ensure compliance.
Since EPA’s establishment, the agency’s enforcement organization has been modified a number of
times, and continues to evolve.20 EPA’s Office of Enforcement and Compliance Assurance
(OECA) at headquarters and in the 10 EPA regional offices sets the general framework for federal
enforcement activities in coordination with the agency’s program offices, states and tribes, and
other federal agencies, particularly DOJ. OECA serves as the central authority for developing and
implementing a national compliance and enforcement policy, and coordinating and distributing
policies and guidance.

(NPM)22 Guidance are primary strategic planning tools that set out national enforcement program
priorities and coordinate and monitor state, regional, and EPA headquarters implementation of
environmental enforcement/compliance activities. EPA’s 10 regional offices, in cooperation with
the states, generally are responsible for a significant portion of the day-to-day federal
enforcement activities. The NEI is developed every three years with the cooperation of EPA
regions and states/tribes, identifying overall program directions as well as specific enforcement
activities/priorities. In June 2013, EPA OECA announced its decision to continue the initiatives
that were the focus of the FY2011-FY2013 NEI released February 22, 2010, for the FY2014-
FY2016 NEI cycle.23 OECA NPM Guidance and other agency NPM Guidance are issued
annually based on a three-year cycle coinciding with the NEI, identifying allocation of resources
and expected outcomes, and serves as the basis for the enforcement agreements (“commitments”)
with the regional offices. The OECA NPM Guidance applies to OECA, all EPA regional
enforcement programs, and states and tribes implementing EPA-approved inspection and
enforcement programs. The agency is currently operating under the FY2014 OECA NPM
Guidance finalized June 14, 2013.24

Federal Pollution Control Laws: How Are They Enforced?

The EPA National Enforcement Investigations Center (NEIC) provides technical expertise to the
agency and states. The center administers an investigative team that assigns investigators to the
regional offices as needed.25 OECA also facilitates EPA’s National Enforcement Training Institute
(NETI), established under Title II of the 1990 Pollution Prosecution Act (P.L. 101-593). NETI
provides a wide spectrum of environmental enforcement training online to international, federal,
state, local, and enforcement personnel, including lawyers, inspectors, civil and criminal
investigators, and technical experts.26
OECA’s headquarters personnel conduct investigations and pursue or participate in national
enforcement cases, particularly those potentially raising issues of national significance. More
often enforcement activities fall to the regional offices. EPA (and the states’) enforcement actions
often require coordination with other federal agencies, most frequently DOJ.
U.S. Department of Justice27
In coordination with EPA, the Department of Justice (DOJ)—at its headquarters and through the
U.S. Attorneys’ offices around the country—plays an integral role in judicial federal enforcement
actions of environmental regulations and statutes. EPA refers cases (including some initiated by
states) to DOJ for an initial determination of whether to file a case in federal court. DOJ
represents EPA in both civil and criminal actions against alleged violators, maintaining close
interaction as needed with EPA, states, and tribes during various stages of litigation. DOJ also
defends environmental laws, programs, and regulations, and represents EPA when the agency
intervenes in, or is sued under, environmental citizen suits. EPA-OECA referred 215 civil cases to
DOJ in FY2012, and reported 320 criminal cases were opened in FY2012.28 Many of these cases
are handled by DOJ’s Environment and Natural Resources Division (ENRD).29 EPA and DOJ
work conjunctively with the other federal agencies as cases warrant.
Other Federal Agencies
EPA and DOJ coordinate with a number of other federal agencies, particularly when taking
criminal action. Key federal agencies include the Federal Bureau of Investigation (FBI),
Department of Transportation (DOT), Department of Homeland Security (DHS, particularly the

Federal Pollution Control Laws: How Are They Enforced?

Coast Guard and U.S. Immigration and Customs Enforcement, or ICE), Fish and Wildlife
Service, Army Corps of Engineers, Defense Criminal Investigative Service, National Oceanic and
Atmospheric Administration (NOAA), U.S. Internal Revenue Service (IRS), and U.S. Securities
and Exchange Commission (SEC). These agencies may provide support directly in response to
violations of laws implemented by EPA, or, as is often the case, in circumstances where multiple
laws have been violated.
States and “Delegated Authority”30
Most federal pollution control statutes, but not all, authorize EPA to delegate to states the
authority to implement national requirements.31 For a state to be authorized, or “delegated,” to
implement a federal environmental program, it must demonstrate the capability to administer
aspects of the program’s requirements, including the capacity to enforce those requirements.
Delegated authority must be authorized under the individual statute, and states must apply for and
receive approval from EPA in order to administer (and enforce) federal environmental programs.
While many federal pollution control laws provide authority for states to assume primary
enforcement responsibilities, there is significant variability across the various laws, including as
to standards states must meet and EPA’s authority in determining whether states are authorized or
have primacy. In some cases, state primacy is almost automatic.
Some federal pollution control laws limit the authority to a specific provision, while others do not
authorize delegation at all. For example, Section 1413 of the Safe Drinking Water Act (SDWA)
authorizes states to assume primary oversight and enforcement responsibility (primacy) for public
water systems,32 and Section 402 of the Clean Water Act (CWA) authorizes state-delegated
responsibilities under that act to issue and enforce discharge permits to industries and
municipalities. Under CERCLA (Superfund), states are authorized to participate in the cleanup of
waste, from taking part in initial site assessment to selecting and carrying out remedial action, and
negotiating with responsible parties. Under FIFRA, states may have primacy for enforcing
compliance requirements contained on labels of registered pesticides, but are not granted
enforcement authority related to registering pesticides or pesticide establishments. Programs
under other laws, such as the Toxic Substances Control Act (TSCA), do not provide authority for
state delegation. EPA can also authorize state government officials to conduct inspections for
environmental compliance on behalf of the agency, subject to the conditions set by EPA, even if a
specific statute does not provide delegation authority. However, there must be authority under the
specific statute for authorizing such inspections.33
Even if delegation is authorized under a federal statute, states may opt not to seek delegation of a
particular environmental program, or they may choose only to implement a select requirement
under a federal law. For example, as of November 2012, 46 states had obtained the authority to
operate the national permitting program under Section 402 of the CWA, but EPA had only

30 The term “delegated authority” has become the most commonly used when referring to EPA’s authority to approve
states’ programs. Federal statutes more often use “primary enforcement responsibility,” “primacy,” “approved,” or
“authorized” states’ responsibility.

Protection Agency

delegated authority to two states to operate the wetlands permitting program under a separate
CWA provision, Section 404.34
A majority of states have been delegated authority to implement and enforce one or more
provisions of the federal pollution control laws.35 Authorized states generally implement the
national laws and regulations by enacting their own legislation and issuing permits, which must
be at least as stringent as the national standards of compliance established by federal law. States
consider and approve environmental permits, monitor and assess environmental noncompliance,
provide compliance assistance and information to the regulated community and the public,
conduct inspections, and take enforcement actions. Local government authorities also play a role
in permitting and monitoring. For example, EPA has delegated authority to implement Section
112 of the Clean Air Act (CAA) to at least three county governments. However, local
governments generally act within the context of assuring states’ requirements. For example, local
authorities may incorporate land use and other issues as well as code requirements (fire,
construction, building safety, plumbing, etc.) in their consideration of permits. A more detailed
discussion of the many facets of local authorities is beyond the scope of this report.
A significant proportion of inspections and enforcement actions are conducted by the states.
Comparable, comprehensive data from the same or similar sources are not readily available for
purposes of directly comparing enforcement activities in states relative to EPA. While EPA
routinely reports trends in its major enforcement actions in the annual OECA accomplishments
reports and on its website, the agency does not include states’ activities. There are a number of
limitations with regard to states’ information currently retained by EPA in its databases (e.g., not
all states report relevant information into the EPA databases, reported data are not provided
consistently from state to state, and reporting requirements are variable from statute to statute).36
EPA has made an effort to enhance and improve enforcement reporting by states. The agency has
been implementing its State Review Framework (SRF) tool developed and introduced in 2004, to
improve its oversight of state enforcement programs.37 Under this SRF tool, EPA representatives
visit and evaluate each state’s compliance and enforcement program based on specified criteria.
In February 2013, on its Enforcement and Compliance History Online website (ECHO; see
Appendix A), EPA released interactive dashboards and comparative maps that include state level
enforcement data for the most recent five years.38 Information includes the number of completed
inspections, types of violations found, enforcement actions taken, and penalties assessed by state,
and users can customize the presentation to view state activity as well as view comparisons with
EPA activity.

Federal Pollution Control Laws: How Are They Enforced?

Through discussions and reports, EPA provides feedback to each state and based on its review,
outlines recommendations for improvement. Full implementation of SRF was initiated by EPA in
July 2005 and the agency reported that reviews of all states and territories were completed in
2007. EPA began conducting Round 2 of reviews in 2008 and completed reviews for most states
by the end of calendar year 2012. OECA, with its partners, has also conducted an evaluation of
the implementation of the first cycle of SRF recommendations and initialed revisions to SRF
guidance for conducting subsequent reviews. OECA continues to work with its partners in
evaluating implementation of SRF recommendations.39 Despite these efforts, there are still
perceived differences between states, EPA regions, and EPA headquarters.
In recent years, ECOS40 has served as a forum to improve coordination and promote joint
strategic planning between the states and EPA. In addition to other strategic planning tools, EPA
and states established the National Environmental Performance Partnership System (performance
partnerships, or NEPPS)41 in 1995 in an effort to improve the effectiveness of EPA-state
coordinated environmental management. Under this system, which includes elements of
compliance and enforcement, EPA and states enter into individual partnerships (performance
partnership agreements) to address jointly agreed-upon priorities based on assessments of
localized environmental conditions. The partnerships can be broad in scope or comprehensive
strategic plans, and often serve as work plans for funding through EPA grants.
Absent delegation, EPA continues to enforce

government deems a state to have failed to
respond to a major violation in a “timely and appropriate” manner. Additionally, when a
noncompliance case involves an emergency or matters of potential national concern, such as
significant risk to public health and safety, the federal government will typically intercede. There
are cases where states request the federal government to step in, and other cases where the federal
government on its own initiative acts on violations that are the subject of state enforcement action
or settlement, known as “overfiling.” EPA contends that overfiling occurs infrequently and that
certain environmental statutory provisions preclude EPA from overfiling. These provisions are not
explicit in all the pollution control statutes, and are limited to specific subsections and
violations.42 Although overfiling of states’ enforcement actions has occurred under various

42 Provisions of the Clean Water Act (CWA) under §309 are often cited as an example of legislation limiting EPA’s
authority to overfile. EPA’s authority to enforce under this section is only limited when a state has commenced an
“appropriate enforcement action” in response to and within 30 days of EPA’s issuance of a notice of violation to the
state (33 U.S.C. §1319(a)(1)); when the state has “commenced and is diligently prosecuting” an action under
comparable state law; or when a penalty assessed under a state-issued final order has been paid, the violation will not
be subject of a civil penalty action under §1319(d) §1321(b) or §1365 (33 U.S.C. §1319(g)(6)).

pollution control statutes, historically, overfiling of Resource Conservation and Recovery Act
(RCRA) violations has been the subject of considerable debate and litigation. States have strongly
objected to overfiling, and the utility and extent of overfiling with respect to environmental
enforcement has been the subject of considerable litigation, debate, and literature.43
Tribal Governments
EPA and states increasingly have recognized the role of tribal governments in environmental
enforcement, where tribes, rather than states, have primary jurisdiction.44 Indian tribes, as
sovereign governments, can establish and enforce environmental programs under their own laws,
but must obtain approval from EPA to administer federal environmental programs on their land.
As with states, some of the federal statutes authorize tribes,45 with EPA approval, to assume
responsibility for implementing certain federal pollution control programs. To obtain EPA
approval, tribes must demonstrate adequate authority and jurisdiction over the activities and lands
to be regulated. Where there is no approved tribal program, EPA exercises its federal authority
and may undertake direct program implementation. In some instances, particularly when there are
criminal violations, EPA may retain a role in compliance and enforcement even when there is an
approved tribal program.
In addition to the federal statutes, a tribal government’s authority for environmental protection
can arise from federal executive orders, treaties, and agreements with the United States and/or
state and local governments,46 some of which explicitly reserve rights pertaining to the
environment. When addressing environmental issues within tribal lands, EPA abides by the
January 24, 1983, American Indian policy statement,47 which reaffirmed the government-to-
government relationship of Indian tribes with the United States.48
Relatively few tribes have obtained authority for implementing federal pollution control laws, and
EPA identified tribal environmental compliance as a national enforcement and compliance
priority in its FY2005-FY2007 and its FY2008-FY201149enforcement strategic plans in an effort
to enhance tribal governments’ capabilities to implement federal environmental statutes. The

44 EPA-approved/authorized state programs generally do not apply in Indian country.
45 Some pollution control laws have been amended to clarify the role of tribal governments in the implementation of
federal environmental programs. For example, from 1986 to 1990, Congress amended the Clean Water Act (33 U.S.C.
§1377(e)(2)), Safe Drinking Water Act (42 U.S.C. §300j-11(b)(1)(B)), and Clean Air Act (42 U.S.C. §7601(d)(2)(B) to
authorize EPA to treat Indian tribes in the same manner as states for purposes of program authorization.

primary focus was public drinking water systems, federal pollution control statutes applicable to
schools, and unregulated dumping of solid waste. EPA’s National Enforcement Initiatives (NEIs)
for FY2011-FY2013, which have been retained for the FY2014-FY2016 cycle, did not designate
Indian Country as one of the six national enforcement initiatives, however, the sector will
continue to be addressed through the structure established under the previous designated initiative
or through the regular program compliance assistance, inspections, investigations, and
enforcement conducted in regional offices and states.50 EPA indicated51 that, during FY2011, EPA
regions continued to provide compliance assistance, conduct compliance monitoring, and take
enforcement in Indian country, particularly in the drinking water area.
Citizens
Private individuals play an important role in enforcing certain aspects of federal pollution control
laws. Citizen participation, specifically authorized by Congress in many of the federal pollution
control statutes, occurs in several ways. Individuals can identify and report violations of the laws,
provide comments on settlements that are reached between the federal government and violators
of the environmental laws in enforcement cases, and initiate enforcement proceedings directly in
response to alleged violations. In addition, individuals may bring actions against EPA for failing
to execute nondiscretionary duties required under federal environmental laws.52
To further enhance public participation and reporting of potential environmental violations, EPA-
OECA introduced the “National Report a Violation” website in January 2006.53 The website
provides access to OECA’s online citizens’ tips and complaints form. EPA reported that the
number of citizen tips and complaints increased from 1,485 in FY2005 to 3,274 in FY2006.
According to EPA, more than 18,000 total tips were reported to date, including more than 7,800
received in FY200854 (not reported for FY2009 through FY2012). Additionally, in FY2009 EPA
introduced the “EPA Fugitives” website to solicit public assistance in locating alleged
environmental criminal fugitives. (See brief overview of the website in the “Criminal Judicial
Enforcement” section of this report.)
Regulated Community
The size and diversity of the regulated community are vast, spanning numerous industrial and
nonindustrial entities, small and large, and their operations. The following discussion provides an
overview of the regulated community, and highlights the role and activities of the key regulated
entities in the enforcement of the primary pollution control statutes.

Federal Pollution Control Laws: How Are They Enforced?

The universe of the regulated community as a whole is very large (see discussion below). The
majority of those in the regulated community are required to comply with multiple statutes
because of the nature of their activities and operations. The regulated community includes a
diverse range of entities and operations, including utilities, refineries, manufacturing and
processing facilities, agriculture producers and processors, mobile sources (e.g., private and
commercial vehicles), and others. Local, state, tribal, and federal governments are also part of the
regulated community, as they are engaged in a range of activities and operations—utilities,
construction, waste and wastewater management, drinking water management, transportation, and
pest management—that generate pollution similar to nongovernment sectors.
Regulated entities vary in their activities and operations, and in size—ranging from small
individual business operations such as dry-cleaners to facilities and operations that are part of
large corporations and conglomerates. Regulatory agencies generally categorize regulated entities
into minor and major emitters/dischargers based on factors such as total earnings, number of
employees, production volume, and amount of emissions, for purposes of implementing and
enforcing the various statutes. In certain circumstances, some of the pollution control statutes
make specific distinctions with regard to major and minor emitters/dischargers. A designation of
“major” generally applies to those entities that, because of their size or operations, have the
potential to have a significant impact on the environment. Most of the statutes and accompanying
regulations include authorities for reducing the stringency, and in some cases providing
exemptions from regulatory requirements to minimize their impacts on small businesses and
operations.
There is no readily available, current, comprehensive list and description of the complete universe
of those who are regulated under all of the major pollution control statutes. EPA has been
criticized for not adequately defining the regulated universe, a step that GAO determined to be a
critical component necessary to evaluate the effectiveness of enforcement.55 EPA-OECA
compiled data regarding the size of the regulated community in September 2001, and estimated a
total universe of more than 41 million.56 Although cited by EPA subsequently from time to time,
most commonly in strategic planning documents, the agency has not updated the estimate.
There are, however, data and information that provide some indications of the size and diversity
of this universe—for example, in EPA’s primary enforcement and compliance databases (see
additional discussion in Appendix A). EPA’s publicly available Enforcement and Compliance
History Online (ECHO) provides for integrated searches of data for more than 800,000 facilities
for compliance with CWA, CAA, and RCRA.57 The data are primarily based on permitted
facilities. Another EPA centrally managed database is the Facility Registry System (FRS), which
primarily identifies “facilities, sites or places” subject to federal pollution control requirements; it
contains more than 2.5 million unique facility records.58 The FRS database is primarily based on
permit information for CWA, CAA, and RCRA, but includes information reported regarding

CERCLA sites. It does not include information indicating the universe regulated under other
statutes. In yet another source, the ECOS indicated that states reported that more than 3 million
regulated facilities required state agency oversight for environmental compliance in 2003.59 The
differences in the various sources are an indication of the difficulty involved in accurately and
consistently tracking the size of the regulated populations.
EPA’s various program offices (e.g., air, water, and waste) maintain and publish information and
profiles regarding characterizations of regulated entities and their operations. Generally included
are estimates of the types and amounts of emissions and discharges, or wastes being handled. For
example, EPA’s Office of Air and Radiation (OAR) maintains a national database of air emissions
estimates for individual point- or major-source categories.60 The database contains information on
stationary and mobile sources that emit common (“criteria”) air pollutants61 and their precursors,
as well as hazardous air pollutants (HAPs).62 The categories presented in these sources do not
reflect 100% of the total number of facilities being regulated.
Another source for characterizing the sectors of the regulated community is EPA’s “Sector
Notebooks.”63 EPA has defined sectors as distinct parts of the economy that share similar
operations, processes or practices, environmental problems, and compliance issues. EPA
recognizes that there are likely a number of circumstances where regulated entities within specific
geographic regions may have unique characteristics that are not fully reflected in the profiles
contained in the sector notebooks. In addition, some of the notebooks were completed several
years ago. Nevertheless, notebook profiles provide fairly comprehensive characterizations of key
sectors included within the regulated community.
Table 2 lists industry and government sectors for which the agency has completed sector
notebooks and developed compliance assistance tools.

ozone, lead, and particulate matter.
62 Under §112 of the Clean Air Act, EPA is to establish technology-based emission standards, called “MACT”
standards, for sources of 188 pollutants listed in the legislation, and to specify categories of sources subject to the
emission standards.

Enforcement at Federal Facilities64
Unless a statutory exemption exists, federal facilities are subject to the federal pollution control
statutes,65 and generally also must adhere to the environmental laws and regulations of the states
and municipalities in which they are located, to the same extent as others in the regulated
community. EPA concluded 61 enforcement actions against federal agencies for alleged violations
of federal pollution control laws during FY2012.66 This is compared to 57 enforcement actions
during FY201267 and 52 during FY2010.68 Federal agencies are also subject to relevant
requirements of executive orders.69

64 See EPA, “Compliance and Enforcement at Federal Facilities,” http://www.epa.gov/compliance/federalfacilities/
index.html.
65 Most federal environmental laws contain provisions that subject federal facilities to federal, state, and local
requirements, and allow such facilities to be sued just as a nongovernmental entity. In addition, such provisions
generally grant the President authority to exempt federal facilities from such requirements when in the “paramount
interest” or (less commonly) the “national security interest” of the United States. See Clean Air Act (42 U.S.C. §7418),
Clean Water Act (33 U.S.C. §1323), Resource Conservation and Recovery Act (42 U.S.C. §6961), and Safe Drinking
Water Act (42 U.S.C. §300j-6). A more limited federal facility provision and presidential exemption is found in the
Comprehensive Environmental Response, Compensation and Liability Act (42 U.S.C. §9620). The Toxic Substances
Control Act nowhere expressly states that federal facilities are subject to the statute, but nonetheless does authorize
presidential exemptions (15 U.S.C. §2621). For discussion of exemptions, particularly as they pertain to DOD, see CRS
Report RS22149, Exemptions from Environmental Law for the Department of Defense (DOD), by David M. Bearden.

Federal Pollution Control Laws: How Are They Enforced?

Nearly $615.0 million in penalties was assessed for federal facility violations during FY2012
compared to $9.0 million assessed in FY2011, and $749,000 in FY2010. In addition, violators
agreed to invest roughly $160.0 million in cleanup and improved operations to comply with
environmental laws, compared to more than $5.0 billion in FY2011 and an estimated $163.0
million in FY2010.70 EPA no longer provides aggregated summaries of federal facility
enforcement actions in its annual results report; however, the agency provides an interactive
mapping tool of concluded enforcement cases that includes the capability to search information
for individual federal facilities based on location.71
Regulating federal facilities under pollution control laws presents certain unique challenges.
Although all are potentially subject to pollution control laws and regulations, a majority of federal
agencies and their facilities are not involved in activities that would generally warrant compliance
requirements. According to EPA, facilities operated by DOD and DOE make up a significant
portion of the universe of “major” federal facilities.72 Major federal facilities generally refer to
those facilities that, because of their size or operations, have the potential to have a significant
impact on the environment. Compliance/enforcement information for DOD and DOE is reported
individually, while other federal agencies are generally categorized together as Civilian Federal
Agencies.73
The major federal pollution control laws provide EPA with authorities to enforce requirements
and impose penalties at federal facilities that are not in compliance. The Federal Facility
Compliance Act of 1992 specifically amended RCRA to clarify that DOD and all other federal
facilities are subject to penalties, fines, permit fees, reviews of plans or studies, and inspection
and monitoring of facilities in connection with federal, state, interstate, or local solid or hazardous
waste regulatory programs.74 The SDWA includes similar language regarding federal facilities,
but most of the other federal environmental laws do not include such specific provisions.
CERCLA (Superfund) Section 120 requires federal agencies with NPL sites to investigate and
clean up the contamination, and significantly contaminated federal facility sites have been listed
on EPA’s National Priorities List (NPL).
Whether other pollution control laws should be amended to clarify their applicability to federal
facilities has been an issue of debate in Congress.

Federal Pollution Control Laws: How Are They Enforced?

Enforcement Response and Compliance Tools
EPA and states apply a set of environmental enforcement tools to identify and correct
noncompliance, restore environmental damage, and impose penalties intended to deter future
violations. Compliance with pollution control laws is addressed through a continuum of response
mechanisms, ranging from compliance assistance to administrative and civil enforcement, to the
stronger criminal enforcement. The spectra of tools, which escalate in terms of their level of
severity and intensity, are authorized in each of the environmental statutes. The following sections
of this report provide a brief overview of the various enforcement response mechanisms.
Over the years, EPA and states have sought to effectively balance the provision of guidance and
assistance to prevent violations or achieve compliance by regulated entities with federal pollution
control requirements, with the imposition of strong enforcement actions in response to violations.
Some critics have depicted environmental enforcement as overly litigious, or requiring
unwarranted remedies. Others counter that actions are not pursued with enough rigor and
frequency, or that penalties are not severe enough to deter noncompliance. EPA officials have
countered that, in some instances, the agency is relying more on settlements and focusing on
requiring increased expenditures on pollution control technologies, and that it is focusing judicial
actions on larger and more complex cases that are expected to result in larger environmental
benefits.
EPA and states maintain a considerable degree of flexibility in determining how to respond to
potential violations, to the extent authorized by individual statutes. Initially, a potential violation
is identified through monitoring, inspecting, citizen reporting, or through self-reporting by the
regulated entity. As a first step in the enforcement process, unless an imminent danger or hazard
has been determined, EPA and states may attempt to obtain corrective actions by simply issuing a
warning or notifying a facility that minor violations may exist, and granting reasonable time for
compliance. EPA or a state may then (or sometimes as a first step) initiate a civil administrative
action under its own authority without involving the judicial process, or file formal civil or
criminal75 judicial actions in court.
Sanctions imposed, whether through negotiated settlements or decisions by the court, generally
include required actions to achieve compliance and to correct environmental damage (injunctive
relief), and may include monetary penalties (and incarceration in the case of criminal violations).
During the last 10 years, settlements increasingly have also included requirements that violators
undertake mutually agreed-upon environmentally beneficial projects supplemental to other
sanctions.76
As noted, EPA, states, and the courts have considerable discretion in determining sanctions and
remedies on a case-by-case basis so that the individual circumstances of each case are
appropriately addressed. A majority of environmental violations are addressed and resolved
administratively by states and EPA, and many of these cases are settled through negotiations
between the government and the alleged violator. For example, during FY2012, EPA issued 1,088
administrative compliance orders and filed 1,780 final administrative penalty order complaints. In
comparison, during FY2012, 115 civil judicial cases were filed with the court, and 144 civil

75 When “... persons willfully or knowingly disregard the law.”
76 See the discussion later in this report on Supplemental Environmental Projects (SEPs).
Congressional Research Service

Federal Pollution Control Laws: How Are They Enforced?

judicial enforcement cases were concluded.77 Civil judicial cases constitute the second-largest
category of environmental enforcement actions. Historically, judicial actions focused on violation
of a single environmental statute. In recent years, EPA and states have increased the frequency of
reliance on a multimedia (multi-statute) approach and multimedia investigations.
The number of administrative and judicial enforcement actions and penalties often fluctuate
significantly from year to year. These fluctuations are generally a reflection of a combination of
factors, including statutory deadlines; new or amended requirements in response to new scientific
information or amended and new regulations; increased or decreased resources; environmental
priority changes at the federal or state levels; and increased or improved monitoring/reporting.
For example, EPA reported that the number of administrative penalty order complaints issued by
the agency more than doubled, from 2,229 complaints in FY2005 to 4,647 in FY2006, then
declined to 2,237 in FY2007, 2,056 in FY2008, 1,914 in FY2009, 1,901 in FY2010, and 1,735 in
FY2011.78 The number of administrative penalty order complaints increased to 1,760 in
FY2012.79 The combined $207.6 million in civil penalties (administrative and judicial) assessed
in FY2012 was the highest in the last five fiscal years.80 Additionally, the total dollar amount of
penalties collected in a given year could reflect the completion of one or two large cases. For
example, EPA reported that a single case accounted for 62% of the total civil penalties assessed
for FY2004. Illustrations of the frequency of enforcement actions by type over time are presented
in Appendix B; this appendix also includes illustrations of administrative and judicial penalties
assessed over time by statute.
Monitoring, Inspections, and Evaluations
Critical steps in enforcing environmental laws include the compilation of monitoring data, and
inspection and evaluation of the activities of the regulated community to determine who is
complying with applicable regulatory requirements and permit conditions, and who is not.
Compliance monitoring, evaluations, and investigations all serve to identify violations and
provide insights into potential priority issue areas that may need to be addressed more broadly.
Monitoring and reporting can be both media program-based (e.g., air, water, waste) and sector-
based (e.g., industrial, mobile source, utilities), and are often included in permit requirements.
Data reported and obtained, as well as observations and evidence collected by inspectors, enable
EPA and states to identify specific environmental problems and determine whether a facility is in
compliance. The information and evidence could eventually be used in an enforcement action.
The mere collection of information or threat of inspection itself often creates an awareness of the
regulators’ interest, and can encourage compliance.
EPA identifies several forms of compliance monitoring that are used differently by the agency and
states, depending upon the statute, the nature of the pollutants, and the types of facilities being
regulated:

Federal Pollution Control Laws: How Are They Enforced?

Self-Monitoring/Reporting: Most environmental laws require (typically through
permitting) regulated entities/facilities to monitor and record their own
compliance status and report some or all of the tracking results to the responsible
regulating authority. In addition to informing the regulators, self-monitoring also
allows a company to measure its performance and evaluate its strategies for
achieving or maintaining compliance.
Review of Records: Regulatory agencies review data and information reported
or otherwise compiled and collected.
Full and Partial Inspections/Evaluations:81 Individual facility environmental
inspections, conducted by EPA regional staff and the states, are the primary tool
used by regulators for initial assessment of compliance. Through sampling,
emissions testing, and other measures, inspections examine environmental
conditions at a facility to determine compliance (or noncompliance) with specific
environmental requirements, and to determine whether conditions present
imminent and substantial endangerment to human health and the environment.
Inspections/evaluations can be conducted all at once or in a series of partial
inspections.
Area Monitoring: Area monitoring looks at environmental conditions in the
vicinity of a facility, or across a certain geographic area. Examples of methods
used for area monitoring include ambient monitoring and remote sensing.
According to EPA’s most recent reported trends data, a total of 19,835 EPA enforcement
inspections and evaluations were conducted under the various statutes during FY2012.82 Although
most inspections are carried out by the states, annual data for the total number of inspections
conducted by states are not readily available due to data-reporting variability and other
limitations. Based on a subset of states surveyed, ECOS reported that roughly 136,000
compliance inspections were conducted by states in 2003 for the major federal environmental
programs—air, drinking water, surface and groundwater, hazardous waste, and solid waste.83 The
total number of inspections reported by ECOS does not account for all inspections conducted by
states under federal pollution control programs—for example, inspections under FIFRA are not
included. In reports to EPA by states under the Pesticide Enforcement Grant program, states,
tribes, and territories reported between 90,000 and 100,000 FIFRA inspections each fiscal year
for FY2006 through FY2008. These FIFRA activities, typically administered by states’
departments of agriculture, are not reflected in the EPA or the ECOS totals.
To put the ECOS number of inspections into perspective, in 2003, the ECOS survey identified
440,000 regulated facilities under these five major environmental programs. EPA’s Facility
Registry System (FRS), which identifies facilities and sites subject to federal environmental
regulation, currently contains unique records for more than 2.5 million facilities (see the above
discussion under the heading Regulated Community). Appendix B presents data on the number
of inspections conducted annually by EPA over time.

81 The CWA requires evaluations instead of investigations, which include reviewing reports, records, and operating
logs; assessing air pollution control devices and operations; and observing visible emissions or conducting stack tests.

Federal Pollution Control Laws: How Are They Enforced?

Civil Administrative Actions
As noted earlier, a majority of environmental pollution control violations are addressed and
resolved administratively by states and EPA without involving a judicial process. EPA or a state
environmental regulatory agency may informally communicate to a regulated entity that there is
an environmental problem, or it may initiate a formal administrative action in the form of a notice
of violation or an Administrative Order to obtain compliance. An Administrative Order imposes
legally enforceable requirements for achieving compliance, generally within a specified time
frame, and may or may not include sanctions and penalties.
An initial step in the enforcement process is often a Notice of Violation, or in some instances, a
warning letter. Warning letters are issued mostly for first-time violations that do not present an
imminent hazard. These notifications are intended to encourage regulated entities to correct
existing problems themselves and come into compliance as quickly as possible. According to
EPA, in many cases, these notices are not escalated to further formal enforcement action because
a facility corrects problems and returns to compliance in response to the notice.
Through administrative enforcement actions, EPA and states may (1) require that the violator take
specific actions to comply with federal environmental standards, (2) revoke the violator’s permit
to discharge, and/or (3) assess a penalty for noncompliance. As indicated previously,
administrative actions frequently end in negotiated settlements. These mutually agreed-upon
resolutions are typically in the form of a Consent Agreement or Final Administrative
Order/Penalty. According to EPA’s FY2012 annual results, during FY2012, EPA initiated 1,088
administrative compliance orders and 1,760 administrative penalty order complaints. EPA
imposed penalties in 1,780 final administrative penalty orders during FY2012, representing a total
value of $52.0 million.84
Federal administrative orders are handled through an administrative adjudicatory process, filed
before an administrative law judge (ALJ), or, in the regions, by EPA’s regional judicial officers
(RJOs). The EPA Office of Administrative Law Judges (OALJ) is an independent office within
the agency.85 ALJs, appointed by the EPA Administrator,86 perform adjudicatory functions and
render decisions in proceedings between EPA and individuals, entities, federal and state agencies,
and others, with regard to administrative actions taken to enforce environmental laws and
regulations. RJOs, designated by each of the EPA Regional Administrators,87 perform similar
adjudicatory functions in the EPA regions. Decisions issued by ALJs and RJOs are subject to
review and appeal to the Environmental Appeals Board (EAB), which also functions
independently of EPA.88 Environmental Appeals Judges are appointed by the EPA
Administrator.89 Federal pollution control laws and regulations specify who may raise an issue
before the EAB, and under what circumstances. EAB decisions often involve reviews of the terms
of federal environmental permits and the amount of assessed financial administrative penalties.

Federal Pollution Control Laws: How Are They Enforced?

Civil Judicial Enforcement
After civil administrative enforcement actions, civil judicial cases constitute the next-largest
category of environmental enforcement. These are lawsuits filed in court against persons or
entities who allegedly have not complied with statutory or regulatory requirements, or, in some
cases, with an Administrative Order. Authorities for pursuing civil judicial actions and penalties
are specified in each of the individual environmental statutes. Civil judicial cases are brought in
federal district court by DOJ on behalf of EPA, and, for the states, by State Attorneys General.
Not all of the cases referred to DOJ are filed with the court. The length of a civil case from its
initiation to completion is highly variable, often extending across several years and sometimes
across different presidential administrations. Like administrative enforcement actions, many civil
judicial actions end as negotiated settlements, typically in the form of Consent Decrees. During
FY2012, EPA-OECA referred 179 civil judicial cases to DOJ; 119 civil judicial complaints were
filed with the court; and 144 cases were concluded (cases filed prior to and during FY2012).90
Criminal Judicial Enforcement
States and EPA may initiate criminal enforcement actions against individuals or entities for
negligent or knowing violations of federal pollution control law. Criminal actions are especially
pursued when a defendant knew, or should have known, that injury or harm would result.
Knowing criminal violations of pollution control requirements are considered deliberate, and not
the result of accident or error.
In addition to the imposition of monetary fines and requirements to correct a violation and restore
damages, conviction of a criminal environmental violation can result in imprisonment. EPA
reported that 320 new environmental crime cases were opened during FY2012,91 13.7% less than
the 371 criminal cases opened in FY2011.92 Authorities for pursuit of criminal actions vary under
each of the statutes. For example, under the SDWA (42 U.S.C. §300h-2(b)), the criminal
violations must be deemed willful—that is, they were committed with intent to do something
prohibited by that law; the CWA (33 U.S.C. §1319(c)) authorizes criminal sanctions against those
who have knowingly or negligently violated that statute.
Recent examples of criminal actions include the illegal disposal of hazardous waste; importation
of certain banned, restricted, or regulated chemicals; the export of hazardous waste without prior
notification or permission of the receiving country; the removal and disposal of regulated
asbestos-containing materials inconsistent with requirements of the law and regulations;
tampering with a drinking water supply; and negligent maintenance resulting in discharge of
hazardous materials.93 EPA maintains a database, Summary of Criminal Prosecutions Database,
which provides the capability to conduct searches for information on concluded criminal
enforcement cases by fiscal year.94

Federal Pollution Control Laws: How Are They Enforced?

The EPA-OECA Office of Criminal Enforcement, Forensics, and Training (OCEFT), the office to
which the agency’s criminal investigators are primarily assigned, oversees implementation of the
agency’s federal environmental crimes investigation program. Within DOJ, the U.S. Attorneys
Offices and ENRD’s Environmental Crimes Section (ECS) prosecute criminal cases and work
closely with EPA’s OCEFT investigators.
State and local law enforcement agencies and their environmental protection-related agencies,
and other federal agencies, are also often key participants in federal environmental criminal
actions. To facilitate investigations and cases, environmental crime task forces have been
established nationally.95 These task forces are composed of representatives from federal
(including representatives from DOJ-ECS and special agents from EPA), state, and local law
enforcement, and environmental regulatory enforcement. The FBI, DOT, Coast Guard, Fish and
Wildlife Service, Army Corps of Engineers, SEC, IRS, and other relevant federal agencies also
may play significant roles.
An increased emphasis on criminal enforcement of the pollution control laws occurred in the mid-
1970s with the issuance of extensive guidelines for proceeding in criminal cases, and in 1981
with the creation of an Office of Criminal Enforcement and the hiring of criminal investigators in
EPA’s regional offices. During the late 1980s, criminal environmental enforcement was further
enhanced when Congress conferred full law enforcement powers upon EPA criminal investigators
as part of the Medical Waste Tracking Act of 1988 (18 U.S.C. §3063). Further, under Title II of
the Pollution Prosecution Act of 1990 (P.L. 101-593), Congress authorized the appointment of a
director of a new Office of Criminal Investigations within EPA, and mandated the hiring of 200
criminal investigators by FY1996.96
Staffing levels of criminal investigators at EPA have been of interest to some Members,
particularly during deliberations on appropriations. For example, the 1990 Pollution Prosecution
Act (P.L. 101-593) required EPA to hire and maintain 200 criminal investigators. A provision in
the House-passed FY2008 Interior and Environmental Agencies Appropriations bill (H.R. 2643)
would have required EPA to bring the total number of investigators up to the level of 200 as
statutorily required.97 The provision was not included in the FY2008 appropriations (P.L. 110-
161, Title II of Division F). Congressional concerns regarding staff and funding for EPA’s
criminal (and civil) enforcement were also expressed in conference report language
accompanying EPA appropriations for FY2003 through FY2005,98 and were the topic of a
congressionally requested EPA-OIG investigation.99

Federal Pollution Control Laws: How Are They Enforced?

EPA’s criminal enforcement agents are authorized law enforcement officers who, in addition to
investigating federal environmental statutes, investigate U.S. Criminal Code (Title 18) violations
often associated with environmental crimes, such as conspiracy, false statements, and interfering
with federal investigations. As noted, Congress has been concerned with the staffing of criminal
investigators.
Table 3 below shows the number of EPA investigators assigned to the criminal enforcement
program for FY1997 through FY2013 (projected), as reported by EPA.100 The number of EPA
special agents increased from about 50 in 1990 to more than 200 by 1998.101 As of September
2007, the number of EPA investigators had dropped to 168; this decline was an issue of concern
in Congress and elsewhere. As a result of an EPA/OECA three-year hiring strategy to increase the
number of criminal investigators, the number of investigators increased to 183 in FY2008, 186 in
FY2009, and 206 in FY2010. The total number of criminal investigators declined to 202 in
FY2011 and EPA expected the current 192 inspectors on board to be 191 by the end of FY2012,
and anticipates this number will remain constant in FY2013.102

committing environmental crimes.103 The site solicits assistance from the public and from law
enforcement agencies to help locate identified environmental “fugitives,” and provides guidance
on how to report information related to the fugitives’ identity and/or current location. EPA
reported that creditable reports received through the website assisted in the arrest or capture of
three fugitives and the surrender of two others during FY2009; four were sentenced and one
awaits trial.104 Comparable information regarding “EPA Fugitives” was not reported by EPA in its
FY2010, FY2011, or FY2012 Annual Results;105 however, the agency indicated that information

obtained through the “Report a Violation” website106 during FY2010 contributed to the opening
of seven active criminal investigations, one of which resulted in an indictment.107 EPA did not
report any similar direct correlations with the “Report a Violation” website in its FY2011 and
FY2012 annual results.
Sanctions108 and Penalties
Sanctions and penalties imposed for violation of federal environmental pollution control laws
have been of interest to some in Congress and the topic of a recent EPA-OIG report.109
Settlements often require that violators achieve compliance and remedy environmental damages
(injunctive relief110). Monetary penalties may be included. Sanctions can also include permanent
or temporary closure of facilities or specific operations, increased monitoring/reporting,
revocation of existing permits or denial of future permits, and barring of receipt of federal
contract funding or other federal assistance.111 The settlement-required corrective and compliance
actions, and the monetary penalties (and possibly incarceration for criminal violations), are
intended to correspond directly with the specific violations (noncompliance) and the extent (or
“gravity”) of action committed.
Monetary penalties collected by the federal government as a result of an environmental
enforcement agreement, order, or decision, are deposited with the U.S. Treasury.112 However,
under CERCLA (Superfund) and CWA, money recovered for the costs of replacing or restoring
natural resources is used to restore the resources.113 In the November 6, 2013, Federal Register,114
EPA published its modifications to civil violation penalties in a final rule revising statutory
penalties at 40 C.F.R. Parts 19 and 27. The final rule increased most of the civil penalties by
adjusting for inflation under the Debt Collection Improvement Act of 1996,115 which requires
federal agencies to adjust civil monetary penalties for inflation every four years.116 Adjusted civil
penalty amounts for the applicable administered statutes are identified in Table 1 in 40 C.F.R.

19.4, as presented in the November 6, 2013 FR Notice.117 These amounts apply to violations that
occur after December 6, 2013. In addition to adjustments to the civil penalty amounts for the
various applicable statutes, a technical revision in the November 2013 FR Notice breaks out the
maximum civil penalty amounts imposed under Section 325(b) of the Emergency Planning and
Community Right-to-Know Act (EPCRA; 42 U.S.C. 11045(b)). Previously grouped together, the
maximum amounts under the three penalty authorities contained in Subsection (b) of EPCRA are
now presented separately in Table 1 of 40 C.F.R. 19.4.118
States may have the explicit administrative authority to impose penalties under individual federal
statutes. For example, the Safe Drinking Water Act requires (unless prohibited by a state’s
constitution) administrative penalty authority for states in certain dollar amounts as a condition of
obtaining and/or retaining primacy for the Public Water System Supervision (PWSS) Program
(§1413 (a)(6)).119 As of October 2012, 55 of 57 states (49) and territories had primacy authority
for the PWSS program.120 Although authorized under several of the other federal pollution control
laws, EPA has not required—and not all states have obtained—administrative penalty authority.
In some states, unlike the federal government, penalties obtained (or shared) as a result of an
environmental enforcement action can be used to directly fund activities for environmental
agencies and programs in the state, and not always to fund the state’s general treasury.
In certain cases where the federal government has led the enforcement action, a state or states
involved in the action may “share” resulting civil monetary penalties to the extent that the
division is permitted by federal, state, and local law. A number of critical factors must be
considered in accordance with EPA guidance121 when determining division of penalties, including
the state’s active participation in prosecuting the case and its authority to collect civil penalties.
EPA’s guidance emphasizes that an agreement to include a division of civil penalties with states
must be completed prior to issuance of a final settlement (order or consent decree).
The several statutes establish various factors to be considered in determining penalties: (1) the
magnitude of environmental harm and the seriousness or gravity of a violation; (2) the economic
benefit or gain to the violator as a result of illegal activity (noncompliance), including the gaining
of a competitive advantage by the delaying or avoidance of pollution control expenditures that
have been incurred by those in compliance; (3) violation history of the violator; and (4) in some
circumstances, the ability of the violator to pay. Other factors, such as the degree of cooperation
by the violator, whether the violation is self-reported, or the extent to which immediate action has
been taken by the violator to mitigate potential harm, may also be considered. Precedents in
previous cases involving similar violations are also a consideration when determining penalties.
The federal pollution control statutes include civil administrative and judicial penalty assessment
authority and limits, which are to be considered by ALJs or the courts in determining the
appropriate penalty. Figure B-3 in Appendix B presents examples of dollar amounts of civil

administrative, civil judicial, and criminal penalties assessed by EPA for the 20-year period
FY1992-FY2012. According to EPA, a significant portion of the total annual dollar amount of all
penalties assessed often reflects penalties assessed in a few cases, and, in some years, a single
case. For example, EPA reported that a major RCRA case accounted for 26% of the total value of
civil penalties reported in FY2006, and that, in FY2005, penalties assessed in a single RCRA
corrective action case accounted for 53% of the reported assessed civil penalties for the year.122
EPA and DOJ have established several policies and guidelines to be considered by counsel when
negotiating agreements and setting penalties.123 EPA-OECA has also developed five computer
models for calculating economic advantage, costs of Supplemental Environmental Projects
(SEPs; see discussion under “Supplemental Environmental Projects (SEPs),” below), and for
measuring the ability to afford compliance requirements and penalties.124 The latter models vary
depending on whether a violator is an individual, municipality, individual facility, or business
entity (small business, large corporation, or conglomerate partnership). Findings of limited ability
or inability to pay are one factor under which an enforcement case may be settled for less than the
economic benefit of noncompliance. The models are to be used in conjunction with the policies
and guidelines for calculating civil penalties.125 The available models are
• BEN, for calculating economic advantage/savings from avoidance of
compliance;
• ABEL, for measuring a noncompliant entity’s (e.g., a corporation’s) ability to
afford compliance and cleanup, and civil penalties;
• INDIPAY, for measuring an individual violator’s ability to afford compliance and
cleanup, and civil penalties;
• MUNIPAY, for measuring a noncompliant municipality’s ability to afford
compliance and cleanup, and civil penalties; and
• PROJECT, for calculating cost to a violator of undertaking a SEP (see the
discussion regarding SEPs later this report).
Penalties Assessed to Federal Facilities126
Most federal pollution control statutes contain a provision expressly subjecting federal facilities
to federal (and state and local) environmental regulation, and waiving sovereign immunity
(thereby allowing federal agencies to be sued by nonfederal entities). Further, many federal

123 For example, EPA’s revised Consolidated Rules of Practice (“CROP”) (64 FR 40138, July 23, 1999) contains

environmental statutes authorize (or arguably authorize) EPA, states, and local governments to
assess civil monetary penalties against federal agencies. (The Supreme Court rejected state
authority to do so under the CWA.)127 DOJ has issued opinions concluding that the CAA and
RCRA underground storage tank provisions give EPA authority to assess civil money penalties
against federal facilities. However, DOJ limits these conclusions to administrative assessment of
penalties. Citing its constitutional theory of the “unitary executive,” DOJ has historically refused
to allow EPA to enforce judicially against other federal agencies, though case law has consistently
been to the contrary. In contrast with EPA enforcement, there is no longer serious doubt that the
Constitution allows states and other nonfederal entities to use the citizen suit provisions in federal
environmental statutes to judicially enforce those laws against federal facilities.
During FY2012, EPA concluded 61 enforcement actions against federal facilities, and assessed
nearly $615.0 million in penalties.128 Federal agencies committed to invest more than $161.0
million in FY2012 to improve their facilities and operations to remedy (clean up) past violations,
to comply with federal laws, and to prevent future violations/pollution. As indicated earlier in this
report, EPA no longer provides aggregated summaries of federal facility enforcement actions in
its annual results report. However, the agency provides an interactive mapping tool of concluded
enforcement cases that includes the capability to search information for individual federal
facilities based on location.129
Supplemental Environmental Projects (SEPs)
In addition to requiring violators to achieve and maintain compliance, and imposing appropriate
sanctions and penalties, enforcement settlements may also include Supplement Environmental
Projects (SEPs).130 SEPs are projects that provide environmental and human health benefits that a
violator may voluntarily agree to undertake in exchange for mitigation of penalties. A project
must be related to the violation, and cannot be an activity the violator is legally required to take to
achieve compliance. Penalties are to be mitigated by a SEP only during settlement negotiation,
prior to imposition of the final penalty.
EPA has established a SEPs policy and developed guidance for their legal requirements and
applicability, and has specified eight categories of acceptable projects.131 These include pollution
prevention, public health, and emergency and preparedness planning. EPA reported that 124 civil
settlement cases during FY2012 included SEPs at an estimated value of $43.6 million, compared
to 103 cases valued at $25.0 million during FY2011.132

Federal Pollution Control Laws: How Are They Enforced?

The incorporation of SEPs into enforcement actions became more common during the last
decade, particularly by federal regulators, because of the potential for direct environmental
benefit from such projects, versus the use of a monetary fine or penalty alone. Some states with
administrative penalty authority have also employed the use of SEPs in their settlements.133
Although these projects are required to be supplemental to other requirements, some contend that,
in practice, inclusion of SEPs may result in lower monetary fines. The extent to which specific
SEPs may have resulted in reduced monetary fines and penalties is not easily calculable.
Environmental Justice and Enforcement/Compliance
Environmental justice (EJ) has been an area of debate among industry and public interest groups,
and ongoing concern highlighted in congressional hearings and legislation. For example, an
administrative provision included in the Omnibus Appropriations Act, 2009 (P.L. 111-8, Title II),
specified that none of the funds made available by this act may be used in contravention of, or to
delay the implementation of, Executive Order No. 12898 relating to federal actions to address
environmental justice in minority populations and low-income populations.134 On August 4, 2011,
the White House announced the signing of a Memorandum of Understanding (MOU) on
Environmental Justice and E.O. 12898 by the heads of 17 federal agencies.135 The MOU included
a Charter to add more structure and efficiency to the Federal Interagency Working Group on
Environmental Justice; processes and procedures to more efficiently assist communities, and
guidance for agencies to better coordinate their EJ activities; and various commitments each
agency will be responsible for meeting. Discussion of the full scope of issues and concerns
regarding environmental justice is beyond the scope of this report. However, the following
discussion briefly highlights environmental justice in the context of enforcement and compliance.
The terms “environmental justice (or injustice)” and “environmental equity (or inequity)” may be
interpreted broadly to describe the perceived level of fairness in the distribution of environmental
quality across groups of people with different characteristics. In this sense, the environmental
impact of any human activity might be evaluated to determine the distribution of environmental
amenities and risks among people categorized according to any population characteristic,
including gender, age, race, place of residence, occupation, income class, or language. In the
political context, however, emphasis generally is more on the distribution of health risks resulting
from exposure to toxic substances in residential or occupational environments of different racial,
ethnic, or socioeconomic groups.

The 1994 Executive Order 12898, Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations, directs each federal agency to “make achieving
environmental justice part of its mission.”136 EPA is the federal agency with lead responsibility for
implementing the executive order. EPA’s Office of Environmental Justice (OEJ), located in
OECA, is responsible for coordinating efforts to include environmental justice into policies and
programs across the agency’s headquarters and regional offices.137 EPA’s OEJ provides
information and technical assistance to other federal agencies for integrating environmental
justice into their missions, engages stakeholders to identify issues and opportunities, and
administers EPA environmental justice grants.138
EPA incorporated Environmental Justice in its FY2011-FY2015 Strategic Plan as the Cross-
Cutting Fundamental Strategy “Working for Environmental Justice and Children’s Health.”139
EPA has initiated implementation of “Plan EJ 2014,” a strategy for expanding its efforts to
integrate environmental justice into its various programs and strengthen “the Agency’s effort to
improve the environmental conditions and public health in overburdened communities.”140 EPA
released an “informational publication” entitled Creating Equitable, Healthy, and Sustainable
Communities: Strategies for Advancing Smart Growth, Environmental Justice, and Equitable
Development
, in February 2013.141
EPA’s OEJ developed the Environmental Justice Strategic Enforcement Assessment Tool
(EJSEAT).142 EJSEAT remains a draft tool in development for internal EPA use only. OECA
expects to use EJSEAT to “consistently identify possible environmental justice areas of concern,”
where potentially disproportionately high and adverse environmental and public health burdens
exist, and assist EPA in making “fair” enforcement and compliance resource deployment
decisions.143 OEJ published a “Toolkit for Assessing Potential Allegations of Environmental
Injustice,” primarily to assist agency staff in assessing allegations of environmental injustice.144
Citizens can evaluate overlap between environmental conditions and demographic characteristics
by using EPA’s EJView (formerly Environmental Justice Geographic Assessment Tool).145

136 See footnote 134.
137 EPA’s Office of Civil Rights (OCR) is responsible for the agency’s administration of Title VI of the Civil Rights
Act of 1964, including processing and investigating administrative complaints under implementing regulations (40
C.F.R. Part 7) prohibiting EPA-funded permitting agencies from “... permitting actions that are intentionally
discriminatory or have a discriminatory effect based on race, color, or national origin.” See http://www.epa.gov/
civilrights/t6home.htm.
138 EPA reports that, since 1994, more than $23.0 million has been awarded to nearly 1,300 community-based
organizations, and local and tribal organizations in the form of Environmental Justice Small Grants. For more

Federal Pollution Control Laws: How Are They Enforced?

Compliance Assistance and Incentive Approaches
A frequent criticism regarding implementation and enforcement of federal environmental
requirements has been an emphasis, historically, on a “command and control” approach. In
response to these criticisms, since the 1990s EPA and states have relied increasingly on
compliance assistance to help the regulated community understand its obligations to prevent
violations and reduce the need for enforcement actions, as well as to assist violators in achieving
compliance. Many states have advocated compliance assistance and developed assistance
programs designed to address specific environmental issues at the local level.146
EPA’s Office of Compliance (OC) within OECA has introduced a number of compliance
assistance programs, many of them developed in conjunction with support from the regions,
states, and tribes.147 Each EPA region has a designated Compliance Assistance Coordinator who
serves as an “expert” within the region on compliance assistance priorities, strategies, and
performance measurement. The coordinators work with subject-matter experts in the regions and
at headquarters in the development of compliance assistance guides and workshops, and
contribute to other assistance activities such as conducting compliance assistance visits.148
In addition to providing compliance assistance across the individual pollution control statutes,
sector-based assistance is also provided. Developed and introduced in partnership between EPA,
states, academia, environmental groups, industry, and other agencies, the National Compliance
Assistance Centers provide sector-specific assistance.149 There are currently 16 sector-specific
web-based compliance assistance centers. As shown in Table 4 below, the sector-specific centers
include agriculture, auto repair, chemical manufacturing, federal facilities, and local governments.

Federal Pollution Control Laws: How Are They Enforced?

The use of compliance incentive approaches has been evolving. Incentives generally are policies
and programs that may reduce or waive penalties and sanctions under specific conditions for
those who voluntarily take steps to evaluate, disclose, correct, and prevent noncompliance.
Examples include self-disclosure programs and related tools such as environmental audit
protocols, Environmental Management Systems, and other innovation projects and programs
designed to achieve environmental benefits.
One of the earliest formal EPA incentive approaches is the EPA Audit Policy—“Incentives for
Self-Policing: Discovery, Disclosure, Correction and Prevention of Violations”—in effect since
1995.150 Under the policy, certain violations are voluntarily reported after being discovered
through self-audit. In many cases EPA eliminates civil penalties, and may offer not to refer certain
violations for criminal prosecution. In early 2007, EPA solicited comments on the question of to
what extent, if any, the agency should consider providing incentives to encourage new owners of
recently acquired facilities to discover and disclose environmental violations, and to correct or
prevent their reoccurrence.151
To further promote compliance through the use of various incentive approaches, EPA encouraged
incentive approaches as part of its core program guidance included in the OECA FY2012 and
FY2013152 National Program Manager Guidance. The FY2013 guidance was distributed to
Regional Administrators and State Environmental Commissioners in April 2012. However, EPA
also continues to evaluate its various voluntary programs.
In March 2009, for example, EPA notified participating stakeholders of its decision to discontinue
the National Performance Track Program, which had been in place since July 2000.153 Designed
as a private-public partnership to supplement EPA’s existing regulatory activities, Performance
Track encouraged facilities who met certain criteria154 to voluntarily work toward environmental
goals that were beyond the legal requirements. EPA reported that at the time of its termination on
May 14, 2009,155 the program had a total membership of nearly 547 facilities (including 82 new
members in 2008) in 49 states and Puerto Rico. In her March 2009 memorandum to Performance

with environmental laws and regulations, commit to achieving measurable environmental results that go beyond
compliance, and provide information to the local community on their environmental activities.” Detailed criteria can be

Federal Pollution Control Laws: How Are They Enforced?

Track stakeholders,156 former EPA Administrator Jackson announced her decision to halt the
program “with the intent of refining those concepts that can lead us to a stronger system of
environmental protection.” EPA had conducted reviews of the Performance Track and the
agency’s environmental leadership programs in general.
EPA’s reliance on incentive approaches has been met with some skepticism by those who favor
more traditional enforcement. Critics are concerned that incentive and voluntary approaches
subtract resources from an already limited pool of enforcement resources. EPA and other
supporters of these approaches contend that they result in cost savings by reducing burdens on
investigators, achieve desired environmental improvements, and allow for the leveraging of
additional resources through partnerships. Aspects of EPA’s incentive approaches have been the
subject of reviews by EPA-OIG and GAO.157
Funding for Enforcement/Compliance Activities
The adequacy of resources needed by EPA, DOJ, and the states to effectively enforce the major
federal environmental pollution control laws is often highlighted during congressional debate of
fiscal year appropriations. Historically, Congress has specified funding levels for certain aspects
of EPA enforcement activities, or required the agency to undertake certain actions under annual
appropriations; an example is the previously mentioned provision included in the House-passed
FY2008 Interior and Environmental Agencies Appropriations bill (H.R. 2643) that would have
required EPA to hire criminal investigators to bring the total number of investigators up to the
statutory requirement of 200, pursuant to the Pollution Prosecution Act of 1990.158 (The provision
was not included in the FY2008 consolidated appropriations.)159
The President’s FY2014 budget request included $625.0 million for EPA’s enforcement program
activities,160 compared to $615.9 million requested for FY2013, $583.4 million enacted for
FY2012, $593.5 million for FY2011, and $596.9 million for FY2010. Detailed allocations for
EPA’s enforcement program activities across several agency appropriations accounts were not
readily available for the FY2014 President’s budget request or FY2013 enacted at the time this
CRS report was updated.
Division F of P.L. 113-6, the Consolidated and Further Continuing Appropriations Act, 2013,
enacted March 26, 2013, appropriated funding for the full fiscal year through September 30,
2013, for seven regular appropriations acts, including Interior, Environment, and Related
Agencies, which funds EPA. FY2013 discretionary appropriations were considered in the context
of the Budget Control Act of 2011 (BCA; P.L. 112-25), which established discretionary spending

limits for FY2012-FY2021.161 Deficit reduction legislation was not enacted by January 15, 2013,
as required by the BCA, triggering an automatic spending reduction process that consisted of a
combination of sequestration and lower discretionary spending caps, and ultimately reductions in
FY2013 funding levels. The FY2013 budgetary resources ultimately available to EPA and other
departments and agencies were based on the application of rescissions specified in Section 1406
of P.L. 113-6 and how the executive branch determined the effects of rescissions and adjustments
associated with automatic spending reductions triggered under the BCA as amended by the
American Taxpayer Relief Act (ATRA; P.L. 112-240).
Section 1113 of P.L. 113-6 required agencies and departments funded in Division F of the law to
report to the House and Senate Appropriations Committees on the allocations of FY2013 funding
by program, project, or activity within each statutory appropriations account, including the
application of sequestration, within 30 days of enactment. Although the agency submitted its
FY2013 Operating Plan to the House and Senate Appropriations Committees on May 14, 2013,
detailed allocations of EPA’s FY2013 funding for enforcement activities across the multiple
appropriations accounts were not readily available.
Table 5, which follows, illustrates the distribution of funding and full-time equivalents (FTEs)
among various enforcement activities across the agency’s appropriations accounts for the FY2013
President’s request and the three prior fiscal years enacted. Because of differences from fiscal
year to fiscal year in the scope of the activities included within each of the accounts, apt direct
comparisons below the appropriations account level are often difficult. These differences include
the addition and discontinuation of program activities, as well as the reorganization and
consolidation certain activities.

CRS-38

Federal Pollution Control Laws: How Are They Enforced?

DOJ’s resource (funding/staff) requirements and outlays associated with its litigation activities
under the major federal pollution control statutes are, in the main, a subset of the funding
(proposed and previously appropriated) for the Environment and Natural Resources Division
(ENRD) in its annual budget justifications. As discussed previously, ENRD is responsible for the
majority of DOJ’s support of the federal pollution control laws, as well as many other
responsibilities, including representing the United States in matters regarding natural resources
and public lands, acquisition of real property by eminent domain for the federal government, and
cases under wildlife protection laws.
DOJ is currently operating under Division B of P.L. 113-6, the Consolidated and Further
Continuing Appropriations Act, 2013, enacted March 26, 2013. However, at the time this CRS
report was updated, specific FY2013 enacted allocations for ENRD were not available. The
President’s FY2014 budget request for DOJ included $112.6 million for ENRD and an estimated
520 FTEs. An additional $23.3 million was included in the President’s FY2014 request for EPA to
be transferred by EPA to DOJ/ENRD through a reimbursable agreement for Superfund work. The
FY2013 request for DOJ included $110.4 million and 582 FTEs for ENRD, and an additional
$23.7 million for up to 115 FTEs was included in the FY2013 request for EPA to be transferred to
DOJ/ENRD through the reimbursable agreement for Superfund work. FY2012 enacted levels for
ENRD were $108.0 million and 582 FTEs, plus $24.6 million for up to 115 FTEs transferred
from EPA. Of the FY2012 enacted amount, including the transfers from EPA, roughly $69.6
million and 367 FTEs were for environmental litigation activities; $10.8 million and 57 FTEs
were for criminal litigation conducted by DOJ’s Environmental Crimes Section; and $58.8
million and 310 FTEs were for civil environmental enforcement and defensive litigation
conducted by the Environmental Enforcement and the Environmental Defense Sections.162
Detailed reporting of federal funding to states and states’ funding contributions for pollution
control enforcement/compliance activities is not readily available. ECOS has tracked a broader
category of state funding and expenditures that it defines as annual “environmental and natural
resource spending,” which, in more recent years, has been primarily based on survey data
reported by states.163 The data, which include state and federal funding, are limited for purposes
of enforcement of federal pollution control laws in that they combine environmental and natural
resource spending. Also, states vary in how they track and report this type of spending. The data
do provide a source of state funding from a national perspective. In its March 2008 state
expenditures report, ECOS only analyzed regulatory environmental agency work, which includes
work pursuant to the primary federal pollution control laws addressed in this report and related
activities. For FY2008 ECOS projected a total expenditure for all states combined of $12.65
billion for these regulatory environmental protection activities. ECOS reported that $3.06 billion,
or less than 25% of the projected amount, was from federal funding to states for these
purposes.164 Based on a February 2010 survey of 36 states and Puerto Rico, ECOS reported that

of the agencies represented by the survey respondents, 2,112 positions were eliminated or were
being held vacant due to budget limitations in FY2010.165
In an August 2010 report,166 ECOS found that
Overall, state environmental agencies’ budgets have decreased from FY2009 to FY2011.
That said, there is a budget increase from FY2009 to FY2010 among states that included
SRF/ARRA [State Revolving Loan Funds/American Recovery and Reinvestment Act of
2009] administrative funds. There has been a slight overall drop in money coming from state
general funds, while funds from the federal government have increased marginally, and
funds from “other” sources, such as those raised through permitting fees, have remained
relatively constant.
Federal appropriations, in particular allocations to states, for adequate staffing and effective
enforcement of federal environmental statutes to protect human health and the environment, will
likely continue to be an issue of concern.
Conclusion
Fully evaluating and measuring the overall effectiveness of current (and past) pollution control
enforcement and compliance activities can be quite complicated. Discussion throughout this
report highlights the difficulties inherent in characterizing the many facets of environmental
enforcement at a macro level, and identifies many of the factors that may contribute to its
perceived successes and shortcomings. However, several indicators do provide insight into a
better understanding of the complexities associated with elements of enforcement, such as the
vastness and diversity of the regulated community, the multiplicity of the activities and priorities
across many regulating entities, and variability across statutes.
Since the establishment of EPA in 1970, Congress has been concerned with a number of
crosscutting issues associated with the enforcement of pollution control statutes and regulations,
as reflected in provisions of enacted and amended environmental legislation over time.
Congressional interest remains heightened, particularly with regard to the substance of
intergovernmental relations, EPA-state relations, and fiscal requirements. Continued involvement
of the 113th Congress with these issues could take several directions. One likely result could be
additional oversight hearings. Alternatively, relevant appropriations legislation may contain
provisions or language regarding funding for specific enforcement activities.

Federal Pollution Control Laws: How Are They Enforced?

Congressional interest might focus on further statutory approaches to establish changes in the
EPA-states’ partnership, such as legislation similar to past proposals concerning refinement of the
National Environmental Performance Partnership System (performance partnerships, or NEPPS)
and the associated grants award process. The 113th Congress is also considering other statute-
specific legislation to address other long-standing concerns that affect certain aspects of EPA
enforcement/compliance activities under the various pollution control laws.
The regulated community, public interest groups, federal and state officials, and Congress are
often divided on whether to pursue legislation that would further expand or constrain
enforcement/compliance. They are similarly divided with respect to proposals that would expand
states’ authority for implementing and enforcing certain aspects of the major federal pollution
control laws.
Views and congressional involvement with respect to these issues are likely to continue to evolve
in the years ahead.

Appendix A. Enforcement/Compliance Databases
and Examples of Reported Results

Enforcement/Compliance Databases and Reporting
Compliance monitoring data are used to manage the compliance and enforcement program, and to
inform the public of enforcement actions taken and penalties imposed. EPA and the states collect
and maintain compliance/enforcement data in many forms. According to EPA’s OECA FY2006
Accomplishments Report, ECOS reported that states collect about 94% of environmental quality
data contained in EPA’s databases, primarily from state-issued permits and monitoring
programs.167 Information is often entered into multiple databases or transferred from state
databases. Historically, the databases were often incompatible, making cross media/statute
queries difficult. In recent years, EPA has been working to integrate several of the individual
databases to allow more cross referencing of compliance data by regulators and to provide
querying capabilities to the public.168
EPA developed a new web-based tool and interactive map that allows the public to obtain detailed
information by location about the environmental pollution control enforcement actions taken at
approximately 4,600 facilities.169 Released in December 2009, the interactive maps show
facilities in the United States where EPA concluded an enforcement action between October 1,
2008, and September 30, 2012 (FY2012). The maps are provided on EPA’s Annual Results
website.170 The maps do not include environmental pollution control enforcement actions taken
by state or local governments.
EPA compiles data from the various databases and provides various statistics in the form of
annual accomplishment and multi-year trends reports.171 Reporting has traditionally focused on
statute-by-statute results, including actions initiated and concluded, and penalties and other
sanctions assessed. The reliability and consistency of EPA and state databases, and how
effectively the reported information can be used as an indicator of environmental progress and the
impacts of environmental enforcement has been an issue of some debate, and questioned in
reviews conducted by EPA-OIG172 and GAO.173 Critics contend, and EPA has long recognized,

that while somewhat indicative of the failure to comply with environmental requirements,
counting enforcement actions alone (“bean counting”) does not provide a complete measure of
the effectiveness of the national environmental enforcement/compliance program.
EPA has expanded its reporting by including estimates of environmental benefits (pollution
reduction and impacts avoided) in its “Annual Results” for the most recent fiscal years.
Overview of Enforcement/Compliance Databases
A number of EPA’s single- and multi-media national databases include enforcement and
compliance data elements. While these databases are generally available to EPA staff, and in
some cases state and local governments, most are not readily available to the public. The
Enforcement and Compliance History Online, or ECHO, developed and maintained by OECA is
the most prominent publicly accessible database. Introduced in 2003, ECHO queries provide a
snapshot of the most recent three years of a facility’s environmental compliance record, but are
limited primarily to certain requirements under the CAA, CWA, and RCRA. EPA continues to
expand the integration and capabilities of this and other databases. Finally, several state
environmental agencies maintain additional information about compliance and enforcement
(beyond what is reported to EPA systems).174
The following brief summaries of several of EPA’s integrated national databases are a
consolidation of descriptions provided on the agency’s website:
Enforcement and Compliance History Online (ECHO)
ECHO is an interactive website that allows users to query permit, inspection, violation,
enforcement action, informal enforcement action, and penalty information for individual or
multiple facilities. Initial queries return a list of relevant facilities, each linked to a “Detailed
Facility Report,” indicating
• whether a facility has been inspected/evaluated,
• occurrence and nature of violations (noncompliance),
• nature of enforcement actions (including penalties) that have been taken, and
• contextual information about the demographics surrounding the facility.
In FY2011 EPA added interactive maps tracking federal enforcement activities (http://www.epa-
echo.gov/echo/maps/enfactions/state_map.html).
In February 2013, EPA released interactive dashboards and comparative maps on the ECHO
website that include state level enforcement data for the most recent five years.175 Information

FRS (a companion to the integrated facility searches in Envirofacts) can be used to create facility
identification records, including geographical location, and to locate sites or places subject to
environmental regulations or oversight (e.g., monitoring sites). Records are based on information
from EPA program national systems, state master facility records, and data collected from EPA’s
Central Data Exchange. See http://ofmpub.epa.gov/sor_internet/registry/facilreg/home/
basicinformation/.
Integrated Compliance Information System (ICIS)
ICIS integrates data that are currently located in several separate data systems. ICIS contains
information on federal administrative and federal judicial cases under the following
environmental statutes: the CAA, CWA, RCRA, EPCRA, TSCA, FIFRA, CERCLA (Superfund),
SDWA, and MPRSA. ICIS also contains information on compliance assistance activities
conducted in EPA regions and headquarters. The web-based system enables states and EPA to
access integrated enforcement and compliance data. The public can only access some of the
federal enforcement and compliance information in ICIS by using the EPA Enforcement Cases
Search and EPA Enforcement SEP Search through ECHO. See http://www.epa.gov/compliance/
data/systems/icis/index.html.
Integrated Data for Enforcement Analysis (IDEA)
IDEA maintains copies of EPA’s air, water, hazardous waste, and enforcement source data
systems that are updated monthly. An internal EPA database, IDEA uses “logical” data integration
to provide a historical profile of inspections, enforcement actions, penalties assessed and toxic
chemicals released, for EPA-regulated facilities. See http://www.epa.gov/compliance/data/
systems/multimedia/idea/index.html.

Online Tracking Information System (OTIS)
OTIS is a collection of search engines which enables EPA, state/local/tribal governments and
certain other federal agencies to access a broad range of data relating to enforcement and
compliance. No public access is available. This web interface application sends queries and draws
data from the IDEA (discussed above) system, which integrates facility data from different EPA
databases. IDEA copies many EPA and non-EPA databases, and organizes the information to
facilitate cross-database analysis. See http://www.epa.gov/compliance/data/systems/multimedia/
aboutotis.html.
A number of other databases, mostly for single media, also include compliance/enforcement data.
Many of these databases are the basis for certain data elements in the various IDEA and OTIS
integrated databases, and typically are not directly available to the public. Other databases include
the Air Facility System (AFS); Permit Compliance System (PCS); Resource Conservation and
Recovery Act Information System (RCRAInfo); National Compliance Data Base System and
Federal Insecticide, Fungicide, and Rodenticide Act/Toxic Substances Control Act Tracking
System (NCDB/FTTS); and Safe Drinking Water Information System/Federal (SDWIS/FED).
Although the information on the integrated systems does not represent “real time” data, it is
updated once a month when OECA refreshes the source data systems. Additionally, EPA routinely
makes improvements to existing aspects of OTIS, IDEA, and ECHO, and often enhances the
system by adding new search capabilities and tools. For example, in December 2012 EPA
announced that it had completed a major, multi-year database modernization for searching Clean
Water Act actions. EPA decommissioned the previous Permit Compliance System (PCS) and
replaced it with the new Integrated Compliance Information System for the National Pollutant
Discharge Elimination System (ICIS-NPDES). As another example, in September 2012 EPA
began adding greenhouse gas (GHG) emission data to the OTIS database, adding GHG Emission
column in the Air and Multimedia search results, and new GHG rows to the Detailed Facility
Report “Facility and Permits and Identifiers” section. Updates and improvements can be tracked
on the OTIS website under the “What’s New” link at http://www.epa-otis.gov/otis/
whats_new.html.
For a more complete list and descriptions of EPA’s enforcement/compliance databases, see EPA’s
“Compliance and Enforcement Data Systems” web page at http://www.epa.gov/compliance/data/
systems/index.html.

Federal Pollution Control Laws: How Are They Enforced?

Appendix B. Examples of Reported Enforcement
Actions and Penalties over Time

The following figures and tables provide examples of the type of enforcement data collected,
compiled and reported over time. They are intended to show proportional relationships of the
various types of enforcement actions (e.g., administrative vs. judicial) in a given year and by
statute, not annual or long-term enforcement trends. To compare the reported activities from year
to year requires more detailed information regarding the specific circumstances in those years.
There can be significant variability from year to year in how data were reported and which
entities reported. EPA has refined terms and definitions in the data elements from year to year.
Other factors that result in variability include the introduction of new regulatory requirements in a
given year, and fruition of statutory deadlines.
The figures presented below reflect longer-term data (15 to 20 years) through FY2012, whereas
the tables generally provide data for the most recent five years, depending on the availability of
data for the most recent fiscal year. Results are presented by action (e.g., administrative, civil
judicial, criminal judicial), and where readily reported, for actions by statute (e.g., Clean Water
Act, Clean Air Act). The data have been compiled from EPA’s annual fiscal year results reports,176
