Notice

Beginning in 1998, EPA recommended in a series of policy memoranda that States accelerate 

the development and adoption of numeric nutrient water quality standards. These policy 

memoranda and other related guidance documents are designed to implement national policy. 

They are not regulations nor do they contain or constitute a determination that new or revised 

nutrient water quality standards are necessary in a particular or site-specific context to meet the 

requirements of the Clean Water Act. State and Tribal decision-makers retain discretion to 

adopt water quality standards based on other scientifically defensible approaches that may 

differ from the recommendations in EPA guidance.

1.0 Purpose of the Report

Nitrogen and phosphorus (or nutrient) pollution is a leading cause of water quality impairments 

in the U.S. As a consequence, EPA has made protecting and restoring the nation’s waters from 

nitrogen and phosphorus pollution a top priority. This priority was most recently articulated in a 

memorandum1

 from EPA Assistant Administrator for Water, Benjamin Grumbles, in May 2007 to 

State, Great Water Body, Interstate, and authorized Tribal Water Programs. 

During the past ten years, EPA has worked in partnership with States, Territories, authorized 

Tribes and certain River Basin Commissions to adopt numeric nutrient criteria into water quality 

standards. These standards are critical for preventing the harmful effects of nitrogen and 

phosphorus pollution in the nation’s waters and for restoring water quality from the impairments 

caused by this pollution. 

This report follows up on the commitment in the May 2007 memorandum that EPA would 

periodically publish a report on State progress in adopting numeric nutrient water quality 

standards2

. The report focuses on progress made by the 50 States3 in adopting numeric 

nutrient standards for their major waterbody types (lakes and reservoirs, rivers and streams, 

estuaries, and wetlands) since 1998 when EPA released its ”National Strategy for the 

Development of Regional Nutrient Criteria”4

. 

It is important to note that there are a range of innovative and effective tools and other 

management approaches to address nutrient pollution problems, including total maximum daily 

loads (TMDLs), best management practices (BMPs), trading, economic incentives, and 

technology-based control approaches. However, EPA believes that numeric nutrient water 

quality standards provide an important foundation to accelerate, guide, calibrate, and evaluate 

the implementation of these tools. 

2.0 Scope of the Nitrogen and Phosphorus Pollution

Problem   Excessive amounts of nitrogen and phosphorus in our nation’s waterways are a form of pollution 

that leads to significant adverse ecological impacts. The effects may occur close to the sources 

of nitrogen and phosphorus pollution or they may be manifested downstream from the sources, 

 

1 Grumbles, B.H. 2007. U.S. EPA. (Memorandum to Directors of State Water Programs, Directors of Great Water Body Programs, Directors of 

Authorized Tribal Water Quality Standards Programs and State and Interstate Water Pollution Control Administrators on Nutrient Pollution and Numeric 

Water Quality Standards. May 25, 2007). 

2

 Water quality standards are established by state law or regulation and include designated uses, criteria to protect uses, and anti-degradation policies. 

This report generally uses the terms "numeric nutrient standards" or "numeric nutrient criteria" to refer to the numeric nutrient criteria adopted into water 

quality standards by the States. The term water quality criteria is used in two different ways under the CWA. Under CWA section 304(a), EPA 

publishes recommended water quality criteria guidance that consists of scientific information such as concentrations of specific chemicals or levels of 

parameters in water that protect aquatic life and human health. States may use these recommended criteria as the basis for water quality criteria 

legally adopted as elements of State water quality standards under CWA section 303(c). 

3

 The five U.S. Territories (U.S. Virgin Islands, Guam, American Samoa, Commonwealth of Northern Mariana Islands, and Commonwealth of Puerto 

Rico), District of Columbia, River Basin Commissions (Delaware River Basin Commission, Ohio River Valley Sanitation Commission) and authorized 

Tribes also develop and adopt numeric nutrient standards; however, they are not included in the report’s cumulative statistics. The status of the District 

of Columbia’s, each Territory’s and River Basin Commission’s progress in adopting numeric nutrient standards is noted in Appendix A (State Profiles) 

and Appendix C (Summary of Territory/Other Numeric Nutrient Standards Adoption: 1998 vs. 2008).

sometimes hundreds of miles away. The well-documented adverse effects of nitrogen and 

phosphorus pollution include harmful algal blooms, reduced spawning grounds and nursery 

habitats, fish kills, oxygen-starved hypoxic or “dead” zones where fish and aquatic life can no 

longer survive, and public health concerns related to impaired drinking water sources and 

increased exposure to toxic microbes such as certain forms of cyanobacteria. Hypoxic events 

caused by nitrogen and phosphorus pollution have become a national concern with regular, 

persistent events occurring in the northern Gulf of Mexico, Chesapeake Bay, Long Island 

Sound, and Hood Canal in Washington State. Collectively, these effects can cause severe 

economic hardship for local tourist-based and fishing economies. The significance of these 

events has led EPA, States, and the public to come together to place a priority on public 

partnerships, collaboration, better science, and improved tools to reduce nutrient pollution. 

As noted above, nitrogen and phosphorus pollution is the cause of significant and widespread 

environmental problems in many of our nation's lakes, reservoirs, rivers, streams, estuaries, and 

wetlands. It is identified as one of the top causes of water quality impairments in the U.S. and a 

persistent threat to water quality. In 2006, EPA documented5

 over 3 million acres of lakes, 

reservoirs, and ponds, 75,000 miles of rivers and streams, nearly 900 square miles of bays and 

estuaries, and over 70,000 acres of wetlands whose water quality was impaired due to nitrogen 

and phosphorus pollution. Forty-nine States have Clean Water Act (CWA) Section 303(d)-listed 

impairments for nitrogen and phosphorus pollution. States have listed over 10,000 nutrientrelated impairments, with 15 States listing more than 200 nutrient-related impairments. 

Population growth, with its accompanying urban, suburban, and agricultural development, 

increases the sources and magnitude of nitrogen and phosphorus pollution.6

3.0 Why Numeric Nutrient Standards are Important   State water quality standards are the foundation for protecting the quality of the nation’s surface 

waters and are the cornerstone of the water quality-based control program mandated by the 

CWA. Standards describe the desired condition of a waterbody and consist of three principal 

elements: (1) the “designated uses” of the state’s waters (e.g., fishing, aquatic life, drinking 

water); (2) “criteria” specifying the amounts of various pollutants, in either numeric or narrative 

form, that may be present in those waters without impairing the designated uses; and (3) antidegradation policies providing for protection of existing water uses and limitations on 

degradation of high quality waters. EPA has recommended that States adopt numeric nutrient 

standards. Numeric standards provide a quantitative measure for nitrogen or phosphorus, as 

well as other parameters. As a result, numeric nutrient standards: 

 

• Provide measurable, objective water quality baselines against which to measure 

environmental progress; 

• Facilitate the writing of protective National Pollution Discharge Elimination System 

(NPDES) permits; 

• Make development of water quality targets in TMDLs faster and easier;

 Sources of nitrogen and phosphorus pollution are typically categorized as point sources (e.g., industrial wastewater discharges, municipal sewage 

treatment discharges, etc.) and non-point sources (e.g., runoff from agricultural lands, range and pasture lands, suburban lawns, golf courses).

• Increase the effectiveness in evaluating success of nutrient runoff minimization 

programs; 

• Provide quantitative targets to support trading programs; 

• Support broader partnerships to employ best management practices (BMPs), land 

stewardship, wetlands protection, voluntary collaboration, and urban storm water runoff 

control strategies; and 

• Identify the water quality goals being sought, and thus enhance greater public 

participation and a more transparent process. 

4.0 Measuring Progress and Reporting Results

This report provides the status of State progress in adopting numeric nutrient criteria into water 

quality standards in the 10 years since EPA issued its “National Strategy for the Development of 

Regional Nutrient Criteria” in June 1998. That strategy recognized the growing problem of 

nitrogen and phosphorus pollution and laid out the expectation that all States should develop 

numeric standards to protect their waters from this pollution. In 20017

, EPA reaffirmed the 

importance of States adopting numeric nutrient standards and encouraged each State to 

develop a plan to adopt standards. EPA also stated the expectation that States and EPA would 

mutually agree to those plans. In 20078

, EPA reiterated its expectation that States adopt 

numeric nutrient standards and urged States to accelerate the pace for adoption of those 

standards. To be most effective, numeric nutrient standards should address causal (both total 

nitrogen [TN] and total phosphorus [TP]) and response (chlorophyll a and water clarity) 

variables for all waters that contribute nutrient loadings to the nation’s waterways. Since 1998, 

EPA has completed a suite of technical tools for States to use in developing numeric nutrient 

criteria (i.e., technical guidance manuals for deriving criteria and eco-regional numeric nutrient 

criteria recommendations). 

This report provides an update on State progress in adopting numeric nutrient standards. 

Current status is characterized in terms of numeric nutrient standards adopted by States and 

approved by EPA for any of EPA’s recommended parameters (TN, TP, chlorophyll a, and 

clarity) for any waterbody type: lakes and reservoirs, rivers and streams, estuaries, and 

wetlands. This report describes the parameters and waterbody types for which States have 

adopted numeric nutrient standards and also notes incremental progress towards that goal. 

This includes State adoption of numeric nutrient water quality standards for one or more 

parameters for all of one or more waterbody types. EPA also recognizes that States have made 

positive, incremental steps by adopting criteria for a parameter(s) for selected waters within a 

waterbody type (e.g., lakes/reservoirs used for recreation versus lakes/reservoirs used solely for 

drinking water, segments of a river rather than all rivers/streams).

The report focuses on the States’ adoption of numeric nutrient standards for protection against 

eutrophication9

 and the effects of eutrophication. The report also documents the status of each 

State’s nutrient criteria plan. A plan, developed by the State, reflects its blueprint for developing 

and adopting numeric nutrient criteria into water quality standards. Nutrient criteria plans vary 

by State due to differences in the types of waters within the State, State priorities, and other 

considerations. In general, however, the plans describe the State’s approach for developing 

numeric nutrient criteria, their process, milestones, and expected dates for the adoption of 

criteria into their water quality standards. Most nutrient criteria plans10 reflect shared 

expectations by States and EPA for developing and adopting numeric nutrient criteria into water 

quality standards. This report documents which States have nutrient criteria plans, what they 

provide for, including the waterbodies and parameters for which criteria will be developed, and 

expected dates of standards adoption. 

5.0 What States Have Achieved   This report is organized into two sections -- national summaries of progress and State profiles. 

The State profiles in Appendix A provide the status of each State’s currently adopted numeric 

nutrient standards and plans for future development and adoption. The national summaries are 

aggregates of data drawn from these profiles. 

National Summaries

1998 to 2008: Trends in State Adoption of Numeric Nutrient Standards

States have developed and adopted numeric nutrient standards for a range of nutrient 

parameters and for a range of waterbody types. Figures 1 and 2 and Table 1 depict the status 

of numeric nutrient standards adoption in 1998 and 2008, respectively. In 1998, six States had 

adopted numeric nutrient standards for at least one nutrient parameter for at least one entire 

waterbody type. By 2008, seven States had adopted numeric nutrient standards for at least one 

nutrient parameter for at least one entire waterbody type. States have made more progress in 

adopting numeric nutrient standards for selected waters within a waterbody type. In 1998, 

seven States had adopted numeric nutrient standards for one or more parameters for part of 

one or more waterbody types. By 2008, 18 States had adopted numeric nutrient standards for 

one or more parameters for part of one or more waterbody types. For more detail on Stateadopted numeric nutrient standards by year and waterbody type, see Appendix B. 

2008 Status of State Adoption of Numeric Nutrient Standards  

The 2008 status of State numeric nutrient standards adoption by waterbody type is summarized 

in Table 1. As in Figures 1 and 2, the status of State adoption is differentiated on the following 

basis: whether a State adopted numeric nutrient standards for both causal and response 

 

9

 The report excludes numeric nutrient standards developed to protect against the acute toxic effects of nitrogen, specifically nitrate and nitrite (NO3

and NO2, respectively), and phosphorus, specifically elemental phosphorus, on humans and/or livestock utilizing surface waters for drinking and source 

water supply. Although important, these numeric nutrient standards typically were not developed to protect against eutrophication. Eutrophication is 

an increase in organic carbon to an aquatic ecosystem caused by primary productivity stimulated by excess nutrients -- typically compounds containing 

nitrogen or phosphorus. Eutrophication can adversely affect aquatic life, recreation, and human health (e.g., toxic microbe production) uses of waters. 

The report also excludes numeric turbidity criteria associated with suspended sediments and which were not developed to protect against 

eutrophication. 

10 Nutrient criteria plans provide a guide for EPA and States to achieve the goal of numeric nutrient standard adoption. They are not legally binding on 

States, do not constitute criteria, nor meet the requirements of the CWA on their own.

parameters for an entire waterbody type, whether a State adopted numeric nutrient standards 

for one or more parameters for an entire waterbody type, whether a State has adopted numeric 

nutrient standards for one or more parameters for selected waters within a waterbody type, and 

if a State has not adopted numeric nutrient standards. State adoption of numeric nutrient 

standards for one or more parameters for selected waters within a waterbody type is also noted 

and further detailed in each State’s profile in Appendix A. 

Lakes/Reservoirs 

• Six States have adopted numeric nutrient standards for one or more parameters for all of 

their lakes/reservoirs; 

• Thirteen States have adopted numeric nutrient standards for one or more parameters for 

part of their lakes/reservoirs; and 

• Thirty-one have not adopted numeric nutrient standards for their lakes/reservoirs. 

Rivers/Streams 

• Five States have adopted numeric nutrient standards for one or more parameters for all 

of their rivers/streams; 

• Nine States have adopted numeric nutrient standards for one or more parameters for 

part of their rivers/streams; and 

• Thirty-six have not adopted numeric nutrient standards for their rivers/streams. 

Estuaries (for the 24 States that have estuaries) 

• Three States have adopted numeric nutrient standards for one or more parameters for 

all of their estuaries; 

• Seven States have adopted numeric nutrient standards for one or more parameters for 

part of their estuaries; and 

• Fourteen States have not adopted numeric nutrient standards for their estuaries. 

Wetlands 

• No State has adopted numeric nutrient standards for one or more parameters for all of 

its wetlands; 

• Four States have adopted numeric nutrient standards for one or more parameters for 

part of their wetlands; 

• Forty-six States have not adopted numeric nutrient standards for their wetlands. 

Status of State Nutrient Criteria Plans

Overall, an analysis of plans indicates the following: 

• 46 of 50 States have plans11 which have been reviewed by EPA and are being used to 

guide numeric nutrient criteria development. 

• Three States (HI12, OR, and SD) have not submitted a plan to EPA. 

• One State (CA) submitted a plan to EPA in 2001, but is no longer using it to guide its 

numeric nutrient criteria development. 

 

11 Forty-three of these plans have been mutually agreed to by EPA and the State; three of these plans have not yet been mutually agreed upon. 12 Hawaii has already adopted standards for its waterbody types.
State Adoption of Numeric Nutrient Standards (1998 – 2008)

8 U.S. Environmental Protection Agency, Office of Water

Of the 46 State plans which EPA reviewed and States use to guide criteria development: 

• 33 plans include projected adoption dates for at least one waterbody type. Of these 33 

plans, and seven include at least one adoption date that has passed and have not been 

met. Four include adoption dates that have been met. 

• 13 plans do not include projected adoption dates. 

As noted previously, these plans vary considerably in terms of whether they include adoption 

dates for standards or interim milestone dates for achieving standards adoption. They also vary 

in terms of whether the original projection dates for adoption of standards have remained 

unchanged or have been routinely updated. For more detail on each State’s plan, see Appendix 

A. 

State Profiles

Existing numeric nutrient standards are provided in Appendix A and B. Numeric nutrient 

standards as of 1998 and 2008 are listed. Appendix A also includes State nutrient criteria plan 

information for developing and adopting numeric nutrient standards to protect against 

eutrophication and its effects. This information includes the date of the plan, the nutrient 

parameters being pursued, priority waterbodies considered for criteria adoption, and projected 

dates for standards adoption.
