Pesticide Use and Water Quality: Are the Laws Complementary or in Conflict?

Summary

This report provides background on the emerging conflict over interpretation and implementation

of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Clean Water Act

(CWA). For the more than 30 years since they were enacted, there had been little apparent

conflict between them. But their relationship has recently been challenged in several arenas,

including the federal courts and regulatory proceedings of the Environmental Protection Agency

(EPA). In this report, a brief discussion of the two laws is followed by a review of the major

litigation of interest. EPA’s efforts to clarify its policy in this area are discussed, including a

regulation issued in 2006 that was subsequently vacated by a federal court, as well as possible

options for EPA and Congress to address the issues further.

FIFRA governs the labeling, distribution, sale, and use of pesticides, including insecticides and

herbicides. Its objective is to protect human health and the environment from unreasonable

adverse effects of pesticides. It establishes a nationally uniform labeling system requiring the

registration of all pesticides sold in the United States, and requiring users to comply with the

national label. The CWA creates a comprehensive regulatory scheme to control the discharge of

pollutants into the nation’s waters; the discharge of pollutants without a permit violates the act.

Several federal court cases testing the relationship between FIFRA and the CWA have drawn

attention since 2001. In two cases concerning pesticide applications by agriculture and natural

resources managers, the U.S. Court of Appeals for the Ninth Circuit held that CWA permits are

required for at least some discharges of FIFRA-regulated pesticides over, into, or near U.S.

waters. It held in a third case that no permit was required for the specific pesticide in question. In

2010, the U.S. Court of Appeals for the Second Circuit ruled that a CWA discharge permit for

mosquito control activities was not required before April 2011.

Several of the rulings alarmed a range of stakeholders who fear that requiring CWA permits for

pesticide application activities would present significant costs, operational difficulties, and

delays. Pressed to clarify its long-standing principle that CWA permits are not required for using

FIFRA-approved products, EPA in 2006 issued a rule to formalize that principle in regulations.

Environmental activists strongly opposed EPA’s actions, arguing that FIFRA does not protect

water quality from harmful pollutant discharges, as the CWA is intended to do. Other

stakeholders, such as pesticide applicators, endorsed the rule. However, the rule was challenged,

and in 2009, a federal court vacated the regulation. The federal government asked the court to

stay the order vacating the exemption for two years, to provide time for working with states to

develop a general permit for pesticide applications covered by the decision. The court denied the

request for rehearing and granted the requested delay, which was extended until October 31,

2011, when EPA issued the permit. Despite the agency’s efforts to minimize regulatory burdens

and cost, the permit is controversial.

Some believe that the controversy will only be resolved by congressional action to clarify the

intersecting scope of the Clean Water Act and FIFRA. The House passed legislation intended to

nullify the 2009 federal court ruling in the 112th and 113th Congresses. Similar bills were

approved by House and Senate committees in the 114th Congress (H.R. 897, S. 659, and S. 1500).

The House passed a modified version of H.R. 897, retitled the Zika Vector Control Act, on May

24, 2016. Separate Senate legislation, S. 2899, was proposed to provide a temporary, 180-day

waiver of the pesticide general permit (PGP) and its reporting requirements for the purpose of

public health pesticide applications of a mosquito control program. Similar waiver provisions

were debated in connection with FY2017 appropriations legislation, but none was enacted.

Pesticide Use and Water Quality: Are the Laws Complementary or in Conflict?

Introduction

It has been noted that “[t]he potential for overlapping and potentially conflicting regulatory scope

between federal statutes is common, especially in the heavily regulated area of environmental

protection.”1 This potential has received attention in connection with implementation of the

Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)2 and the Federal Water Pollution

Control Act (Clean Water Act, CWA).3 FIFRA requires the Environmental Protection Agency

(EPA) to regulate the sale and use of pesticides in the United States through registration and

labeling. The CWA is the principal federal law governing pollution in the nation’s surface waters.

Pesticides used to control weeds, insects, and other pests receive public attention because of

potential impacts on humans and the environment. Depending on the chemical, possible health

effects from overexposure to pesticides include cancer, reproductive or nervous-system disorders,

and acute toxicity. Similar effects are possible in the aquatic environment. Recent studies suggest

that some pesticides can disrupt endocrine systems and affect reproduction by interfering with

natural hormones.4 However, many pesticides and their breakdown products do not have

standards or guidelines, and current standards and guidelines do not yet account for exposure to

mixtures and seasonal pulses of high concentrations. Effects of pesticides on aquatic life are a

concern, because intensive surveys done by the U.S. Geological Survey found that more than

one-half of streams sampled had concentrations of at least one pesticide that exceeded an EPA

guideline for the protection of aquatic life. Whereas most toxicity and exposure assessments of

pesticides are based on controlled experiments with a single contaminant, sampling by the U.S.

Geological Survey found that most contamination of waterbodies occurs as pesticide mixtures.5

For the more than 30 years since Congress enacted FIFRA and the Clean Water Act, there had

been little apparent direct conflict between them. EPA’s operating principle during that time had

been that pesticides used according to the requirements of FIFRA do not require regulatory

consideration under the CWA. EPA had never required CWA permits for use of FIFRA-approved

materials, and EPA rules did not specifically address the issue. However, EPA’s interpretation and

operating practice regarding the relationship between the two laws have recently been challenged

in several arenas. Federal courts have been one of two battlegrounds so far where the potential

conflict between the regulatory scope of these two laws has been waged. EPA regulatory

proceedings have been the second battleground area. Congressional action adds a third testing of

the issues.

At issue is how FIFRA-approved pesticides that are sprayed over or into waters are regulated and,

specifically, whether the FIFRA regulatory regime is sufficient alone to ensure protection of water

quality or whether such pesticide application requires approval under a CWA permit. The issue

arose initially over challenges to some routine practices in the West (weed control in irrigation

ditches and spraying for silvicultural pest control on U.S. Forest Service lands). It subsequently

drew more attention in connection with efforts by public health officials throughout the country to

combat mosquito-borne illnesses such as West Nile virus. The litigation created uncertainty over

whether application of pesticides and herbicides to waterbodies requires a water discharge permit.

EPA tried to promulgate policy to clarify the relationship of the two laws and to address conflicts

resulting from several judicial rulings, ultimately in a regulation issued in 2006. That rule was

challenged by multiple parties, and in 2009, a federal appellate court vacated the rule. A related

issue of interest to many pesticide applicators, but not yet addressed by EPA policy or rule,

concerns pesticides that unintentionally impact waterbodies through drift or migration from

nearby land, such as a field of crops.

This report provides background on the conflict over interpretation and implementation of FIFRA

and the Clean Water Act. A brief discussion of the two laws is followed by a review of the major

litigation of interest. EPA’s efforts to clarify its policy in this area, its 2006 rule, and the 2009

federal court ruling are discussed, as well as possible options for EPA and Congress to further

address the FIFRA-CWA issues. In 2011 EPA issued a general CWA permit (the pesticide general

permit, or PGP) in response to the court ruling; the permit was renewed in 2016. Despite EPA’s

efforts to streamline the permit and its applicability, the permit is controversial. Congress has for

some time considered legislation to nullify the court’s ruling, but no measure has been enacted.

The Laws

FIFRA is a regulatory statute governing the licensing, distribution, sale, and use of pesticides,

including insecticides, fungicides, rodenticides, and other designated classes of chemicals. Its

objective is to protect human health and the environment from unreasonable adverse effects of

pesticides. To that end, it establishes a nationally uniform pesticide labeling system requiring the

registration of all pesticides and herbicides sold in the United States, and requiring users to

comply with conditions of use included on the national label. A FIFRA label encompasses the

terms on which a chemical is registered, and its requirements become part of FIFRA’s regulatory

scheme. In registering the chemical, EPA makes a finding that the chemical “when used in

accordance with widespread and commonly recognized practice ... will not generally cause

unreasonable adverse effects on the environment” (7 U.S.C. §136a(c)(5)(D)).

EPA reviews scientific data submitted by pesticide manufacturers on toxicity and behavior in the

environment to evaluate risks and exposure associated with the pesticide product’s use and takes

into account the costs and benefits of various pesticide uses. If a registration is granted, the

agency specifies the approved uses and conditions of use, which the registrant must explain on

the product label. EPA may classify and register a pesticide product for general use or for

restricted use (those judged to be more dangerous to the applicator or to the environment which

can only be applied by or under the direct supervision of a person who has been trained and

certified). FIFRA preempts state, local, and tribal regulations stricter than or different from EPA

rules with respect to labeling requirements, but allows states and localities to adopt more

restrictive conditions with regard to sale and use.

Use of a pesticide product in a manner not consistent with its label is prohibited, and the law

provides civil and criminal penalties for violations. Under FIFRA, EPA generally enforces the

law’s requirements. However, the law also gives states with adequate enforcement procedures,

laws, and regulations primary authority for enforcing FIFRA provisions related to pesticide use.

The objective of the CWA is to “restore and maintain the chemical, physical, and biological

integrity of the Nation’s waters.” To that end, it creates a comprehensive regulatory scheme to

control the discharge of waste and pollutants; the discharge of pollutants into waters of the United

States without a permit violates the act. The permit requirement is at the heart of the act’s

Congressional Research Service

compliance and enforcement strategy. Several aspects of these core requirements in the law are

important to evaluating whether the CWA applies to specific activities, including whether there is

a discharge from a point source (a discrete conveyance such as a pipe, ditch, container, vessel, or

other floating craft), whether the discharge is made into waters of the United States, and whether

the material discharged is a pollutant; all of these terms are defined in the act. Especially key in

the current context is whether pesticides are pollutants under the act. This issue has been central

to much of the judicial and regulatory debate over whether the two laws, CWA and FIFRA, are

complementary or in conflict. CWA Section 502(6) (33 U.S.C. §1362(6)) defines pollutant thus:

The term “pollutant” means dredged spoil, solid waste, incinerator residue, sewage,

garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive

materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt and industrial,

municipal, and agricultural waste discharged into water.

Section 402 of the act establishes the National Pollutant Discharge Elimination System (NPDES)

permitting requirement, which regulates the lawful discharge of pollutants. The act defines

“discharge of a pollutant” to mean “any addition of any pollutant to navigable waters from any

point source” (CWA §502(12); 33 U.S.C. §1362(12)). Discharges are permitted if they are

authorized under a NPDES permit that meets CWA requirements, including protecting the

receiving waters. NPDES permits specify limits on what pollutants may be discharged and in

what amounts. They also include monitoring and reporting requirements. They are either

individual case-by-case permits or general permits applicable to similar categories of activities

and similar waste discharges. Under the CWA, qualified states issue NPDES permits to regulated

sources and enforce permits, and the law allows states to adopt water quality requirements more

stringent than federal rules. As of 2015, 46 states have been delegated authority to administer the

permit program; EPA issues discharge permits in the remaining states.

The NPDES permit is the act’s principal enforcement tool. EPA may issue a compliance order or

bring a civil suit in U.S. district court against persons who violate the terms of a permit, and

stiffer penalties are authorized for criminal violations of the act. As a practical matter, the

majority of actions taken to enforce the law are undertaken by states, both because states issue the

majority of permits to dischargers and because the federal government lacks the resources for

day-to-day monitoring and enforcement. In addition, individuals may bring a citizen suit in U.S.

district court against persons who violate the terms of a CWA-authorized permit or who discharge

without a valid permit. FIFRA does not authorize citizen suits.

Throughout the United States, pesticides often are applied in, onto, or near waterbodies to control

weeds and insects. Whether those pesticides are adversely affecting water quality has not been a

disputed issue until recently. EPA’s long-standing practice and interpretation of the laws was that

a CWA permit is not required when pesticide application is done in a manner consistent with

FIFRA and its regulations. But that interpretation was challenged in several lawsuits brought

since the late 1990s that have been decided since 2001.

The Litigation

Five federal court cases testing the relationship between FIFRA and the CWA have drawn the

most attention, three in the U.S. Court of Appeals for the Ninth Circuit in the West, concerning

pesticide applications by agricultural and natural resource managers, and two in the Second

Circuit Court of Appeals in the East, involving the use of pesticides by government and public

health authorities for mosquito control. These cases have been brought principally under the

citizen suit provisions of the CWA. Two of the Ninth Circuit decisions have held that CWA

permits are required for at least some activity involving the point source discharge of FIFRA-

regulated pesticides over or into waters of the United States, and the third held that a permit was

not required because the specific pesticide was not a chemical waste. The Second Circuit ruled in

two cases; most recently, it ruled that trucks and helicopters that discharge pesticides are point

sources, but it deferred requiring permits until EPA issues a CWA general permit, which is

discussed below.

The Ninth Circuit Cases

The first of the major cases on these issues involved application of herbicides in irrigation

ditches. In the case, a major issue was whether the application of pesticides constitutes the

discharge of a pollutant. Environmental groups challenged application of an aquatic herbicide

called Magnicide H to kill weeds and algae and sought to require that the applicator, a municipal

corporation that operates a system of irrigation canals in Oregon, obtain an NPDES permit.

The U.S. Court of Appeals for the Ninth Circuit endorsed the lower court’s ruling that the

pesticide was a pollutant under the CWA, and that the irrigation canals into which the pesticide

was being sprayed are “waters of the United States.”6 But it rejected the lower court’s holding

that a CWA permit was not required because the pesticide was properly regulated by FIFRA and

had an EPA-approved FIFRA label. The appeals court ruled that FIFRA and CWA have different

purposes and that, as such, neither could be controlling on the application of the other. The court

said that FIFRA creates a comprehensive regulatory scheme for the labeling of pesticides,

requiring that all insecticides and herbicides sold in the United States be registered with the EPA.

It and the CWA have different, although complementary, purposes, the court said, and using a

pesticide with a FIFRA-approved label does not obviate the need to obtain a CWA permit. The

FIFRA label is the same nationwide. The CWA permit considers local environmental conditions,

which the FIFRA label does not. Thus, a nationwide label on a FIFRA-regulated chemical could

not be controlling on whether a CWA permit is required, because it does not account for locationspecific requirements. The court reversed the district court’s grant of summary judgment in favor

of the defendants.7

Several of the states within the Ninth Circuit subsequently took actions to respond to this ruling.

California and Washington amended their water quality program rules to require NPDES permits

for pesticide applicators. Oregon did not mandate permits, but suggested that pesticide applicators

obtain state-issued permits to protect against lawsuits. Other states outside of the Ninth Circuit

have continued their long-standing practice of not issuing permits to persons who apply pesticides

to waters of the United States.

The second major case in the West involved an annual U.S. Forest Service (USFS) aerial spray

program over national forest lands in Oregon and Washington. Environmental groups filed a

lawsuit challenging the spraying program, saying that the environmental impact statement (EIS)

prepared by the USFS was inadequate and that the Forest Service had failed to obtain a CWA

permit, which they argued is required for this type of aerial spraying. The appeals court reversed

the district court’s grant of summary judgment for the Forest Service and instructed the lower

court to enter an injunction prohibiting the federal agency from further spraying until it acquires

In view of the Supreme Court’s June 2006 decision in Rapanos v. United States (547 U.S. 715, 2006), coverage of

irrigation canals as “waters of the United States” may depend on case-specific circumstances, because the Court’s

plurality opinion in this case made specific reference to Headwaters, Inc. v. Talent Irrigation District. For additional

an NPDES permit and completes a revised EIS.8 The court disagreed with the argument of the

Forest Service that the spraying is nonpoint source water pollution, which does not require an

NPDES permit. The court held that the insecticides meet the CWA definition of “pollutant” and

that the application came from an aircraft equipped with spraying apparatus, thus meeting all of

the elements of the CWA’s definition of point source pollution.

In September 2003, the EPA General Counsel issued a legal memorandum to officials in states

located in the Ninth Circuit responding to the Forsgren case. The memorandum said that EPA

disagreed with the court’s holding in the case and that outside the Ninth Circuit, EPA would

continue its long-standing interpretation of FIFRA and the CWA. Within the Ninth Circuit, the

memo said, EPA would not acquiesce to the ruling in the case of materials other than pesticides

(such as those used for fire control), or in circumstances where pesticides are not applied directly

over and into waters of the United States.9

The third Ninth Circuit case involved an effort by the Montana Department of Fish, Wildlife and

Parks to intentionally apply the pesticide antimycin to a river in order to remove non-native trout

species and thus to allow reintroducing a threatened fish species into the river. The director of the

department was sued under the citizen suit provision of the CWA by a citizen who sought to

require the department to obtain an NPDES permit before applying the pesticide.

The court held in this instance that no NPDES permit was required, because the facts of the case

demonstrated that, following application as intended, the antimycin dissipated rapidly, leaving no

excess portions or residual chemical that should be characterized as chemical waste, and thus is

not a pollutant under the act.10 Intentionally applied and properly performing pesticides are not

pollutants, the court said.

The court distinguished this case from its ruling in Headwaters, saying that the factual scenarios

differ, because “in that case the ‘chemical waste’ for which a NPDES permit was required was not

a pesticide serving a beneficial purpose and intentionally applied to water, but was a chemical

that remained in the water after the Magnicide H performed its intended, beneficial function.”11

Further, the court stated that its analysis accords with EPA’s construction of the CWA’s definition

of “chemical waste” in the context of intentionally applied pesticides, and that the agency’s 2003

Interim Statement and Guidance addressing the issue (discussed below) is entitled to some

deference. EPA’s interpretation as presented in that Interim Statement is reasonable and not in

conflict with the expressed intent of Congress, the court said.

The Second Circuit Cases

Two cases in the U.S. Court of Appeals for the Second Circuit involved the use of pesticides for

mosquito control. In the first case, several residents of the Town of Amherst, NY, sought to halt

aerial application of pesticides without a CWA permit. The district court initially dismissed the

case, stating that spray drift is not chemical waste under the CWA and that the pesticide use was

best regulated under FIFRA. But the appeals court remanded the case to the district court for

further development of the record.12 Although this ruling may not be cited as precedent, it is

notable in that, while EPA had filed an amicus curiae brief providing its views on this particular

case, the court invited EPA to offer its views broadly on the policy and legal questions. The court

stated:

Until the EPA articulates a clear interpretation of current law—among other things,

whether properly used pesticides released into or over waters of the United States can

trigger the requirement for NPDES permits ...—the question of whether properly used

pesticides can become pollutants that violate the CWA will remain open. Participation by

the EPA in this litigation in any way that permits articulation of the EPA’s interpretation

of the law in this situation would be of great assistance to the courts. 13

The second pertinent case in the Second Circuit also involved the use of pesticides for control of

mosquitoes. Plaintiffs in the case, a citizens group, sought an injunction to halt the aerial and

ground spraying, arguing that although the pesticides were properly regulated under FIFRA, the

spraying program involved the discharge of a pollutant without a CWA permit, and thus was a

violation of that law. A federal district court held that FIFRA-compliant spraying activity did not

amount to the discharge of a pollutant into navigable waters from a point source, and thus did not

violate the CWA. In March 2010, the Second Circuit Court of Appeals disagreed with the district

court’s finding that trucks and helicopters were not “point source,” which are required to have

CWA permits in order to discharge lawfully, but this court held that no permits would be required

for the challenged activities until EPA issues a general permit, as it did in 2011 (see discussion

below, “Options for EPA”).14

Other Litigation

Other lawsuits followed these cases. For example, private citizens who operate an organic fruit

farm in Gem County, Idaho, brought suit against the local mosquito abatement district there,

seeking to require a CWA permit for pesticide spraying. Finding itself in the proverbial spot

“between a rock and a hard place,” the mosquito abatement district applied for a permit from

EPA, which the agency declined to issue, based on its long-standing policy and legal

interpretation. Thereafter, the mosquito abatement district filed a lawsuit against EPA in an

attempt to obtain a declaration that a CWA permit is not needed and to avoid the citizen suit

litigation, which is pending in federal court in Idaho. The mosquito abatement district asked the

federal court either for a judgment saying that no permit is required or, if the court were to

determine otherwise, an order directing EPA to process its CWA permit application. In January

2005, the federal district court in the District of Columbia dismissed the case because the

mosquito abatement district and EPA were in agreement that no CWA permit is required for

pesticide applications that are consistent with FIFRA.15

In other locations, citizen groups have given notice, as required by the CWA, of possible lawsuits

to expand the precedent from the Ninth Circuit cases to other types of operations. For example,

two actions were threatened against Maine blueberry farmers for failing to obtain a CWA permit

for spraying pesticides that may drift off-target from land into waterbodies. In response to the

litigation pressure, however, both farmers subsequently announced plans to cease aerial spraying

and instead rely on ground spraying, until such time as government or the courts clarify the law.

EPA’s Initial Regulatory Responses

The rulings by the Ninth Circuit in the Talent and Forsgren cases and possible endorsement by

other courts greatly alarmed a range of stakeholders in the regulated community, including

forestry, agriculture, and pesticide applicators, as well as municipal and public health officials

concerned with the need to control mosquitoes and other vectors associated with diseases such as

West Nile virus and malaria. They feared that CWA permit requirements would be extended to

agricultural and other activities that have not traditionally been regulated under the CWA. They

argue that if permits tailored to particular circumstances are deemed necessary, such requirements

would present significant costs, operational difficulties, and delays to applicators. They also

would put pressure on limited federal and state CWA permitting resources. In their view,

requiring permits will not be environmentally helpful, but the expense and long delays of

permitting proceedings will hamper programs that are needed for controlling pests that threaten

public health and crops. In response, EPA issued interpretive guidance documents and in 2005

proposed a rulemaking to formalize its long-standing position on CWA-FIFRA issues. A final rule

was promulgated in November 2006 but was vacated by a federal court in 2009, as described

next.

2005 Guidance

After the Altman v. Town of Amherst ruling in 2002, industry, states, and others, including some in

Congress, pressed EPA to clarify the emerging conflicts over the two laws. EPA responded with a

guidance document in 2005.16 The agency’s consistent position, expressed in the guidance, was

that pesticides applied in a manner consistent with FIFRA do not constitute either chemical

wastes or biological materials under the definition of pollutant in Section 502(6) of the CWA. The

rationale for this position was that it is consistent with over 30 years of CWA administration. At

the same time, EPA said that pesticide applications in violation of FIFRA, that is, when not used

or applied according to applicable labeling requirements, would be subject to all relevant statutes,

including the Clean Water Act.

Environmental activists strongly objected to EPA’s position in the guidance, which they viewed as

contrary to the judicial rulings. These groups reiterated points made by the Ninth Circuit court in

the Headwaters and Forsgren rulings, namely that chemical and biological pesticides are

pollutants within the meaning of the CWA, because the law defines pollutants broadly and

includes, among other substances, chemical wastes, biological materials, and agricultural wastes.

As that court has declared, environmentalists said, FIFRA does not override the CWA, and the

two statutes must work in tandem to prevent injury to aquatic life. They also argued that EPA was

wrongly deciding that materials with beneficial uses should not be construed as pollutants under

the CWA.

Environmentalists’ objections also went to the policy problems of relying on FIFRA to protect

water quality from pesticide applications, as that would be the result of EPA’s position. That

position, critics said, turns on whether the pesticide application conforms procedurally with

FIFRA requirements, not what is the water quality impact of that pesticide. Other concerns raised

by critics included the fact that while the FIFRA registration process calls for ecological risk

assessment that may be adequate for producing nationally applicable labels, it does not ensure

that local water quality standards are maintained and does not account for additive or synergistic

effects of multiple pollutants discharged to a particular waterbody. Environmentalists argued that

the CWA provides the means to determine whether, and under what conditions, it is safe to

discharge a particular pesticide into a particular body of water, and that FIFRA’s nationally

uniform labeling system cannot do that. FIFRA is not specifically charged with ensuring the

chemical, physical, and biological integrity of U.S. waterways, and satisfaction of a pesticide’s

FIFRA labeling criteria does not automatically satisfy water quality concerns, as the NPDES

permit process is intended to do. They also maintained that FIFRA fails to consider the lasting

effects that pesticide residues have on a local ecosystem and that localized analysis of the

environmental impact of pollutant discharges under the CWA is necessary, due to the toxic

residues that remain after pesticide application, which FIFRA does not address.

Industry welcomed the thrust of the EPA guidance but also urged that it be broadened.

Agricultural groups requested that EPA include other classes of applications under the guidance,

such as aquaculture and crop production. Beyond the types of uses described in the guidance,

some argued that EPA should additionally clarify that CWA permits are not required in the case of

pesticides that are applied over land and then inadvertently impact waterbodies through drift and

migration. Many requested that EPA address the issues definitively in a rulemaking, rather than in

nonbinding guidance. In their view, without clear regulatory language supporting EPA’s

interpretation, pesticide applicators would still face the prospect of citizen lawsuits and NPDES

permit requirements.

Many states and local governments, including agriculture agencies, irrigation districts, and

mosquito abatement districts, strongly endorsed EPA’s proposed clarification of its interpretation

of the two laws. However, a few—especially states located in the jurisdiction of the federal Ninth

Circuit—expressed a different view. The Oregon Department of Environmental Quality and

California State Water Resources Control Board commented that the Interim Statement conflicted

with legal precedent in the Headwaters case. They urged EPA, if it wishes to create an exemption

for pesticide applications conducted in compliance with FIFRA, to ask Congress to amend the

Clean Water Act and FIFRA accordingly.

EPA’s Regulatory Response

At the same time that it issued the 2005 guidance, EPA proposed a rulemaking to codify the

substance of the guidance in CWA regulations; it promulgated the rule in November 2006.17 The

rule added two specific circumstances that would be excluded from NPDES permit requirements,

when the application complies with relevant requirements of FIFRA:

the application of pesticides directly to waters of the United States in order to

control pests (e.g., to control mosquito larvae or aquatic weeds); and

the application of pesticides to control pests that are present over waters of the

United States, including near such waters, where a portion of the pesticides will

unavoidably be deposited to waters of the United States in order to target the

pests effectively.

In the rule, EPA provided a lengthy discussion of its rationale that pesticides, when applied

pursuant to FIFRA, are not chemical wastes or biological materials and thus are not what the

CWA defines as “pollutants” (see discussion, page 3). However, EPA also acknowledged that

application of pesticides may leave residual materials in U.S. waters after the product has served

its beneficial purpose and that these residual materials may be “pollutants” under the act at that

later time. Nonetheless, even in such cases, EPA said, the initial application of the pesticide does

not require an NPDES permit because EPA does not consider it to be a pollutant at the time of its

discharge into water.18 The agency also responded to some public comments that had criticized

the adequacy of FIFRA’s registration process for consideration of water quality, local conditions,

etc. EPA said that the “regulatory and nonregulatory tools under FIFRA provide means of

addressing water quality problems arising from the use of pesticides,” particularly the registration

and re-registration processes, which consider both human health and aquatic resource impacts.19

Judicial Challenge to the EPA Rule

The 2006 rule prompted multiple lawsuits by industry and environmental groups in almost every

judicial circuit nationwide. The litigation was consolidated in the Sixth Circuit U.S. Court of

Appeals. Industry’s challenge argued that the rule was arbitrary and capricious because it treated

pesticides applied in violation of FIFRA as pollutants, while treating the same pesticides used in

compliance with FIFRA as nonpollutants. It also sought to expand the rule to apply to all

pesticides and all agricultural applications of pesticides, including applications to land that drift

over or into water. Environmentalists’ challenge claimed that, by exempting FIFRA-compliant

applications of pesticides from CWA requirements, EPA ignored its duties under the Clean Water

Act.

The court’s ruling was issued January 7, 2009.20 EPA had argued that at the time of discharge, a

pesticide is a nonpollutant. Excess pesticide or pesticide residues do not exist until after the

discharge is complete, EPA said, and therefore should be treated as nonpoint source pollutants

that do not require CWA permits. The court rejected EPA’s attempt to “inject[] a temporal

requirement to the ‘discharge of a pollutant,’” and it said that such an interpretation is

unsupported by the CWA, and is also contrary to the purpose of the permitting program. The

court said, “If the EPA’s interpretation were allowed to stand, discharges that are innocuous at the

time they are made but extremely harmful at a later point would not be subject to the permitting

program.” It concluded that “there is no room for the EPA’s argument that residual and excess

pesticides do not require an NPDES permit,” and the court thus vacated the rule. The vacatur was

scheduled to take effect April 9, 2009, but subsequently the Sixth Circuit granted the

government’s request to delay the effective date of the ruling for two years, so that EPA could

develop a regulatory response, as discussed below, leaving the rule in effect in the meantime.21

The Supreme Court declined to review the Sixth Circuit’s ruling.

Congressional Interest and Options

Congressional interest in these issues became apparent after the first federal appeals court ruling

in the 2001 Headwaters v. Talent ruling. Two congressional hearings focused on implications of

the cases for pesticide use generally and for local governments’ efforts to control mosquito-borne

illnesses such as West Nile Virus. Also, a hearing also was held on legislation introduced in the

109th Congress to clarify the scope of the CWA regarding the use of FIFRA-approved pesticides,

fire retardants, and biological control organisms.

The first of these hearings was in October 2002, when a House Transportation and Infrastructure

subcommittee held a fact-finding hearing on the issues.22 The subcommittee’s particular concern

derived in part from the fact that one of the key practices used to manage stormwater runoff,

which is regulated under the Clean Water Act, is to collect and hold it in retention ponds, basins,

drainage ditches, etc. Such practices can be at odds with the public health objective of controlling

insect-breeding habitat by eliminating or draining sources of standing water. Stormwater

management practices typically allow collected water to drain slowly, while public health efforts

would prefer that it be removed quickly. Another way to address the public health concerns is to

spray pesticides on stormwater management structures and other areas of standing waters. The

question for this subcommittee was the uncertainty raised by the litigation over the CWA-FIFRA

issues for communities, industries, and others needing to maintain stormwater control systems.

An EPA official, while acknowledging that the issue of CWA jurisdiction over pesticide spraying

is “new territory” for the agency, said that EPA believed there is no inherent conflict between

protecting water quality and preventing mosquito-borne disease. At the hearing, some Members

and witnesses urged EPA to provide guidance to resolve uncertainties raised by the court rulings.

The second hearing, held by a House Government Reform subcommittee in October 2004,

examined challenges to controlling West Nile Virus.23 During the hearing, some Members and

witnesses expressed the view that EPA’s July 2003 interim guidance, while helpful in clarifying

EPA’s position, failed to resolve all legal uncertainty, since it would not bind nonfederal entities

or bar citizen lawsuits. Witnesses said that EPA’s guidance was a nonbinding legal document that

would not deter filing of citizen lawsuits seeking to impose a permit requirement. Supporters of

this view urged EPA to settle the legal questions through a formal rulemaking to revise CWA

rules. An EPA official said that even if EPA were to promulgate a rule (as it subsequently did),

states would still have the discretion to continue to require non-NPDES permits, and a formal rule

would not preclude citizen lawsuits from seeking to force localities to file for permits. EPA

acknowledged these same points in the 2005 guidance. Others at this hearing agreed on the need

for a formal rulemaking, but recommended that in doing so, EPA should reverse the interpretation

detailed in the guidance, not codify it.

In the 108th Congress, Senate appropriators included report language calling on EPA to finalize

the interim guidance by December 2004 and to clarify the long-standing distinction between

agriculture and silviculture activities that do and do not require CWA permits.24

In 2003, a number of House and Senate Members urged the Bush Administration to support

Supreme Court review of the Forsgren case, but ultimately the Administration did not endorse

industry’s request for a review, and the Court did not grant certiorari. Some Members of Congress

also submitted comments in support of the July 2003 interim guidance document and the January

2005 regulatory proposal.

Options for EPA

As described above, in January 2009, the Sixth Circuit U.S. Court of Appeals rejected EPA’s

rationale for its 2006 rule that attempted to specify circumstances in which pesticides applied to

waters of the United States do not require NPDES permits. The court appeared to leave little

room for EPA to fashion a new rule consistent with the agency’s long-standing view that FIFRAcompliant applications do not require CWA permits. Agriculture industry groups were fearful that

the court’s ruling would lead to permit requirements for each pesticide application, placing

significant burdens on industry and EPA. Accordingly, several industry groups (the American

Farm Bureau Federation, American Forest and Paper Association, and CropLife America, the

trade organization for agriculture and pest management) petitioned for a rehearing of the case by

the full Sixth Circuit court, but the rehearing request was rejected.

The federal government did not seek a rehearing of the case. Instead, the government petitioned

the court for a two-year stay of the order vacating the exemption, to give EPA time to work with

states and the regulated community to develop a general permit for pesticide applications covered

by the decision. State water pollution agencies supported the government’s request for the twoyear delay, which the court granted.

EPA’s Pesticide General Permit

The two basic types of NPDES permits are individual permits that are tailored for a specific

discharger, and general permits covering categories of point sources that have common elements

and that discharge the same types of wastes. General permits allow the permitting authority to

allocate resources efficiently, especially when there is potentially a large number of permittees,

and to provide timely permit coverage. Both individual and general permits are enforceable by

the permitting authority and by private citizens (in federal court).

EPA uses its authority to issue NPDES general permits frequently, such as a general permit to

cover discharges incidental to the normal operation of vessels (vessel general permit, or VGP)

that applies to approximately 69,000 vessels.25 Typically, dischargers seeking coverage under a

general permit are required to submit a notice of intent to be covered by the permit, but this can

be modified. For example, in the VGP, EPA provided automatic coverage for about 20,000 of the

covered vessels. Still, even with general permits, development and implementation issues arise,

including how EPA specifies applicable discharge limits based on technology available to treat

pollutant constituents found in the discharge (i.e., effluent limits), and limits that are protective of

the designated uses of the impacted water (i.e., water quality-based effluent limits), as required by

the CWA.

EPA issued the pesticide general permit on October 31, 2011, as required by the federal court.26

EPA estimated that the universe of activities affected by the court’s ruling is approximately 5.6

million applications annually, which are performed by 365,000 applicators, including mosquito

and other flying insect pest control, aquatic weed and algae control, aquatic nuisance animal

control, and forest canopy pest control. The permit covers about 500 different pesticide active

ingredients that are contained in approximately 3,700 product labels.

The permit applies to a variety of entities, including agricultural interests involved in crop and

timber tract production, forest nurseries, and operating irrigation systems; pesticide and

agricultural chemical manufacturing; mosquito or other vector control districts and commercial

applicators that service them; utilities (e.g., electric power, natural gas, water supply and

wastewater); and government agencies and departments engaged in air and water resource

management and conservation. It requires all operators to minimize pesticide discharges to waters

by practices such as using the lowest effect amount of pesticide product that is optimal for

controlling the target pest. It also requires operators to prepare pesticide discharge management

plans to document their pest management practices. Permittees must monitor for observable

adverse effects in the treatment area and where the pesticides are discharged to U.S. waters.

The permit does not cover agricultural stormwater runoff or irrigation return flow, as these

discharges are statutorily exempt from CWA permitting, and it also does not cover terrestrial

application to control pests on agricultural crops or forest floors (i.e., it would not apply to

pesticide applications that do not result in a discharge to U.S. waters). The EPA general permit

applies in states and areas where EPA is the NPDES permitting authority, but it is being used as a

model for other states to develop their own general permits.27

The 2011 permit included Endangered Species Act (ESA) provisions, following consultation with

the National Oceanic and Atmospheric Administration (NOAA) Fisheries Service. As a result,

coverage under the permit was available only for discharges not likely to adversely affect species

that are listed as endangered or threatened under the ESA.28

Renewed PGP in 2016

With expiration of the 2011 pesticide general permit (PGP) on October 31, 2016, EPA renewed

the permit for another five years on October 25. The renewed permit has the same applicability,

conditions, and requirements as the 2011 permit. In a regulatory first, EPA added electronic

notification by persons seeking or terminating coverage and for filing annual reports required by

the permit. The new permit also adds a provision that requires a permit applicant to consider the

adverse effects of spraying on certain species identified as potentially at risk, but not formally

listed, under the ESA. The 2016 permit is effective in the same states, the District of Columbia,

U.S. territories, Indian lands, and federal facilities as the 2011 permit; states will issue their own

NPDES permits for pesticide discharges in the other states, either by adopting EPA’s general

permit or adapting it to suit their conditions.29

Other EPA Options

One issue that EPA could address separately, in addition to the general NPDES permit, is

pesticide drift, that is, pesticide particles and droplets that migrate from the application area,

27

The CWA authorizes EPA to delegate NPDES permitting authority to qualified states, and EPA has done so for the

majority of states. For this permit, EPA is the permitting authority in Massachusetts, New Mexico, New Hampshire,

Oklahoma, Alaska, Idaho, and the District of Columbia; Indian lands in all states except Maine; all U.S. territories

except the Virgin Islands; and at federal facilities in Delaware, Vermont, Colorado, and Washington.

which can affect people’s health and the environment, as well as damage nearby crops. The

Federal Register Notice accompanying the 2006 rule had noted that, at the time, EPA was

awaiting advice from a workgroup of its Pesticide Program Dialogue Committee, which could

recommend further actions. This committee was established in 1995 as a forum to provide

feedback to EPA on various pesticide regulatory, policy, and program implementation issues. It is

authorized pursuant to the Federal Advisory Committee Act (FACA), which details requirements

for the management and oversight of federal advisory committees to ensure impartial and relevant

expertise and advice to EPA and other agencies. In 2006, the committee convened a Spray Drift

Workgroup charged with studying the issue of pesticide drift across water and its accompanying

impact on water quality and wildlife. The following year, the workgroup finalized a report that

focused on issues related to product labeling, applicator training, and practices and equipment to

mitigate drift and adverse effects.

In 2009, EPA proposed new pesticide labels to reduce the drifting of spray and dust from

pesticide applications. The agency also has proposed several guidance documents addressing

pesticide spray drift, including guidance for pesticide labeling and guidance on how off-site spray

drift will be evaluated for ecological, drinking water, and human health risk assessments. In 2014,

EPA announced a voluntary Drift Reduction Technology program under which manufacturers of

spraying devices may conduct studies of their products to see how much drift they prevent. EPA

will then assign a rating, based on how much spray drift is reduced by the device.

Other options for EPA relate to implementation of FIFRA and procedures used to evaluate the

risks of pesticides during the registration process. Environmentalists have argued for some time

that EPA’s risk review procedures are inadequate because they fail to account for synergistic and

additive effects, as well as sub-lethal and indirect effects of pollutants on the environment. In

2003, EPA convened a task force of officials from its pesticide and water quality offices to

explore, among other things, whether the agency’s pesticide review processes are protective

enough to meet water quality standard limits. One outcome of the task force’s review could be

changes to implementation of FIFRA in order to address some of these concerns. Subsequently,

EPA officials held a series of regional meetings with state pesticide and water quality agencies

and other stakeholders and announced plans to complete a series of white papers on how to

harmonize methods used by the agency’s Office of Water and the Office of Pesticide Programs for

ecological assessment of pesticide chemicals’ water quality risks. The white papers are intended

to address what officials acknowledge is a gap between the way the CWA and FIFRA approach

pesticide risk and to support a consistent and common set of effects characterization methods

using best available information.

Legislative Options

Prior to the 2009 federal court ruling that vacated EPA’s rule, some environmental activists

favored legislation to clarify that NPDES permits are required, since they contended that the rule

was unlawful. However, no such legislation was introduced. Others argued during this time that

legislation is not needed because, in their view, the CWA is clear enough that permits are required

for discharge of pesticides from point sources. The federal court’s review of the EPA rule supports

that view. But, following the court’s ruling, other stakeholders came to favor legislation to

support a narrow view of the CWA’s jurisdiction on this issue. Although many acknowledge that

any such legislative effort would be controversial and could be seen as representing not

clarification but, rather, an environmental rollback, lawmakers in the House and Senate have

repeatedly attempted to pass such a bill.

Legislation intended to clarify that permits are not required for some or all pesticide spraying

activity was first introduced in the 109th Congress (H.R. 1749 and S. 1269, the Pest Management

Congressional Research Service

13

Pesticide Use and Water Quality: Are the Laws Complementary or in Conflict?

and Fire Suppression Flexibility Act). These bills would have provided that NPDES permits are

not required for the use of FIFRA-approved pesticides; chemicals, fire retardants, or water used

for fire suppression; biological organisms used for plant pest or weed control; or silviculture

activities such as timber harvesting that are not currently regulated as point source activities.

As discussed above, EPA’s 2006 rule (although subsequently vacated by a federal court)

addressed situations in which pesticides are put directly in waters to control pests (e.g.,

controlling mosquito larvae or aquatic weeds) or cases of pesticides that are present over water

and a portion of the pesticide is deposited in the water (e.g., aerial application to a forest canopy

where waters of the United States may be present below the canopy) and excluded these

situations from requiring a CWA permit. The proposed legislation in the 109th Congress, in

addition to codifying these policies, also would have addressed other, broader circumstances that

EPA had declined to include in the rule: applications over land areas that may drift over and into

waters of the United States, broad exemption of activities for preventing or controlling plant pests

or noxious weeds, and use of fire retardants.

In 2005, a House Transportation and Infrastructure subcommittee held a hearing on H.R. 1749.30

Witnesses representing a number of sectors that are pesticide users (state foresters, western

irrigation districts, and farmers) testified in support of the legislation, saying that it would resolve

existing legal uncertainties about permitting. An EPA witness said that the agency’s thenproposed rulemaking was intended to reduce uncertainty about the relationship between FIFRA

and the CWA. The EPA official did not expressly endorse the legislation, but he said that EPA

appreciated congressional efforts to reduce potential confusion over these issues. There was no

further action on either H.R. 1749 or S. 1269 during the 109th Congress, and no similar bills were

introduced in the 110th Congress.

Legislation on this issue was introduced in the 111th Congress. One proposal was contained in

identical bills, S. 3735 and H.R. 6087. The intention of the these bills was similar to that of the

earlier bills—to clarify permitting requirements under other laws and, effectively, to nullify the

2009 federal court ruling—but the 111th Congress legislation differed in several respects. First, it

would have amended FIFRA, while the earlier bills would have amended the CWA. Second, the

bills would not expressly have exempted chemicals, fire retardants, water used for fire

suppression, or specified silviculture activities from permit requirements. Third, S. 3735 and H.R.

6087 were broader in their potential application. The earlier bills were limited to exempting

FIFRA-authorized activities from CWA permits, but the 111th Congress legislation would have

exempted FIFRA-authorized activities from permits required by other federal environmental laws

(including the CWA), other federal nonenvironmental permits or licenses, as well as state or local

laws and ordinances. Pursuant to authority in FIFRA, many state and local governments control

pesticide application within their jurisdictions by employing permitting systems to restrict aerial

application of pesticides, or by imposing notice-and-posting requirements.

Another bill in the 111th Congress was H.R. 6273. This bill also was intended to nullify the 2009

federal court ruling, but it was narrower in scope than the other two measures. It would have

amended both FIFRA and the CWA to provide that a CWA permit shall not be required by EPA,

nor shall EPA require a state to require a permit, for the application of any pesticide that is subject

to FIFRA if it is applied in conformance with that act.

112th and 113th Congresses

Attention to these issues resumed in the 112th Congress, because the PGP has remained

controversial. Critics continue to argue that requirements of CWA and FIFRA are duplicative,

although others disagree, saying that the purposes and approaches of the two laws differ greatly

(see discussion of “The Laws” above). Even as they are beginning to implement permit

requirements for pesticide discharges, water quality officials in some states have said that they see

little water quality benefit from the permit. Despite EPA’s contention that many farms are not

affected by the National Cotton Council ruling and do not need CWA permits for their pesticide

applications,31 the PGP has been particularly controversial in the agriculture community.

At a joint hearing of subcommittees of the House Agriculture and Transportation and

Infrastructure committees in February 2011, draft legislation to overturn the National Cotton

Council ruling was discussed. Subsequently introduced as H.R. 872, the bill would amend FIFRA

and the CWA to provide that neither EPA nor a state may require a CWA permit for discharge of a

pesticide whose use has been authorized pursuant to FIFRA. The bill defined specified

circumstances where a permit would be required (e.g., municipal or industrial treatment works

effluent that contains pesticide or pesticide residue). At the hearing, some Members indicated that

the bill had been drafted with EPA’s technical assistance, but the Administration’s official position

on H.R. 872 was unknown.

The House passed H.R. 872 on March 31, 2011, by a vote of 292-130. The Senate Committee on

Agriculture, Nutrition, and Forestry approved the bill without amendment in June 2011. The text

of H.R. 872 also was included as a provision of H.R. 2584, a bill providing FY2012

appropriations for EPA, which the House debated in July 2011, without taking final action.

Related bills in the 112th Congress included S. 3605 (similar to H.R. 872, with the addition of a

report to Congress on effectiveness of regulatory actions related to pesticide registration and

protecting water quality) and S. 718 (a bill to amend only FIFRA to clarify that, notwithstanding

any other law, no permit shall be required for use of a FIFRA-registered pesticide or organisms or

practices covered by the Plant Protection Act).

In July 2012, the House Agriculture Committee ordered reported the 2012 farm bill (H.R. 6083,

the Federal Agriculture Reform and Risk Management Act). A provision identical to Housepassed H.R. 872 was included in the legislation. The Senate had previously passed its version of a

2012 farm bill (S. 3240); it did not include a similar provision. The 112th Congress did not take

final action on comprehensive farm bill legislation.

Legislation to nullify the 2009 federal court ruling also was introduced in the 113th Congress

(H.R. 935, similar to H.R. 872 in the 112th Congress; S. 175, similar to S. 718 in the 112th

Congress; and S. 802, similar to S. 3605 in the 112th Congress). The House passed H.R. 935 on

July 31, 2014, by a vote of 267-161.

In addition, a provision similar to H.R. 935 was included in farm bill legislation approved by the

House in June 2013 (H.R. 2642). However, the Senate-passed version of farm bill renewal

legislation (S. 954) did not include a similar provision. The 2014 farm bill, enacted in February

2014 (the Agricultural Act of 2014, P.L. 113-79), also did not include a provision to overturn the

Sixth Circuit ruling.

Pesticide Use and Water Quality: Are the Laws Complementary or in Conflict?

114th Congress

The PGP requirements have been in place for more than five years. In March 2015, an EPA

official stated during congressional testimony that the agency is not aware of any issues with the

permit or of any instances of individuals not being able to apply a pesticide in a timely manner.

Further, EPA is not aware of any active litigation in connection with the PGP.

Nevertheless, it remains controversial. Critics of the permit continue to argue that its CWA

requirements are duplicative of FIFRA and are burdensome, due to costs that applicators incur in

obtaining permits. Critics also say that applicators are vulnerable to potential CWA citizen suit

litigation. Supporters of the permit respond that the two laws are different because the CWA

allows evaluation of pesticides’ impacts on localized waterbodies, while FIFRA makes more

generalized determination of impacts on human health and environmental risk. They believe that

the regulatory process for the PGP has been reasonable and workable for pest control operations

and agriculture interests.

In the 114th Congress, legislation similar to bills passed by the House in the 112th and 113th

Congresses to overturn requirements for the PGP was introduced. In the Senate, the Environment

and Public Works Committee approved S. 1500 on August 5, 2015. This bill proposed to clarify

congressional intent regarding the regulation of the use of pesticides in or near U.S. waters. It

differed from previous versions of the legislation in that it also would require EPA to report to

Congress on better coordination of efforts by the agency’s water quality and pesticides offices in

order to analyze the water quality impacts of pesticides and the effectiveness of current pesticide

registration actions at protecting water quality. On January 20, 2016, the Senate Environment

Committee approved S. 659, the Bipartisan Sportsmen’s Act of 2015, with an amendment

identical to the text of S. 1500.

In the House, legislation identical to H.R. 935 from the 113th Congress was introduced (H.R. 897,

the Reducing Regulatory Burdens Act) and was approved by the House Agriculture Committee in

March 2015. The House passed a modified version on May 24, 2016. Proponents argued that the

legislation is needed so that public health agencies that spray pesticides to respond to mosquitoes

that carry the Zika virus and other diseases could focus resources on disease-carrying vectors,

rather than CWA permitting. Opponents asserted that the legislation would weaken environmental

protections by relaxing standards for pesticide application to the point that waterbodies will

become impaired or threatened by pesticides. As passed, the legislation was retitled the Zika

Vector Control Act and modified previous versions by including a sunset provision, under which

the legislation would expire on September 30, 2018, and the PGP would again become effective

after that date.

Separate Senate legislation, S. 2899, the Zika Response and Regulatory Relief Act, was

introduced to provide a temporary, 180-day waiver of the PGP and its reporting requirements

solely for the purpose of public health pesticide applications of a mosquito control program.

Proposals to provide a PGP waiver also arose in connection with FY2017 appropriations

legislation, in bills addressing whether and how to provide funds to control the spread of the Zika

virus in the United States. On June 23, 2016, the House passed a bill providing $1.1 billion in

Zika funding and other appropriations (H.R. 2577). However, the Senate failed on two occasions

to approve this legislation, due to controversies over several provisions. One of the controversies

was a section in the House-passed bill that would have provided a temporary waiver (until

September 30, 2018) of the PGP for control of mosquitos or mosquito larvae to prevent or control

the Zika virus.

Congressional Research Service

16

Pesticide Use and Water Quality: Are the Laws Complementary or in Conflict?

As the beginning of FY2017 approached on October 1, 2016, and Congress had not yet enacted

any full-year appropriations bills, the issue also was raised in connection with legislation to

continue FY2016 government funding for a short period of time extending beyond the November

2016 election. On September 28, the Senate and House passed a bill providing a 10-week

continuing resolution, from October 1 until December 9, 2016 (P.L. 114-223).32 As passed, while

the bill included Zika funding, it did not include provisions that would waive requirements of the

PGP, either temporarily or permanently. Congress subsequently passed a second continuing

appropriations resolution, extending FY2016 funding from December 10, 2016, through April 28,

2017 (P.L. 114-254), with no language affecting the PGP.

The Congressional Research Service (CRS) is a federal legislative branch agency, housed inside the

Library of Congress, charged with providing the United States Congress non-partisan advice on

issues that may come before Congress.

EveryCRSReport.com republishes CRS reports that are available to all Congressional staff. The

reports are not classified, and Members of Congress routinely make individual reports available to

the public.

Prior to our republication, we redacted names, phone numbers and email addresses of analysts

who produced the reports. We also added this page to the report. We have not intentionally made

any other changes to any report published on EveryCRSReport.com.

CRS reports, as a work of the United States government, are not subject to copyright protection in

the United States. Any CRS report may be reproduced and distributed in its entirety without

permission from CRS. However, as a CRS report may include copyrighted images or material from a

third party, you may need to obtain permission of the copyright holder if you wish to copy or

otherwise use copyrighted material.

Information in a CRS report should not be relied upon for purposes other than public

understanding of information that has been provided by CRS to members of Congress in

connection with CRS' institutional role.

EveryCRSReport.com is not a government website and is not affiliated with CRS. We do not claim

copyright on any CRS report we have republished.

This is a copy of a public record, reproduced as it was published. It is not legal advice, and it may not be the version a court would rely on. Check the official source before you cite it.

We need a few to keep you signed in and the library working. The rest help us see which pages people use and where they get stuck. They stay off unless you say yes.
