EPA's Standards to Address Nutrient Pollution in Florida's Lakes and

Flowing Waters

Frequently Asked Questions

1.	What is "nutrient pollution"?

Nutrient pollution is made up of phosphorus and nitrogen and causes harmful algae
blooms — the thick, green muck that fouls clear water and harms ecosystems across the
state of Florida. Such algae blooms produce toxins harmful to both humans and animals,
deplete oxygen needed for fish and shellfish survival, smother aquatic vegetation and
discolor water. Approximately 375,000 acres of lakes, 1,900 miles of rivers and streams
and 550 square miles of estuaries in Florida are hurt by nutrient pollution. Nutrient
pollution comes from wastewater, urban stormwater, industry, and excess fertilizer and
manure that flow off the land into waterways.

2.	What is EPA's "numeric standards" rule?

Today's rule sets specific numeric water quality targets for waters across most of Florida.
The Florida Wildlife Federation filed a 2008 lawsuit against EPA under the Clean Water
Act to require EPA to set numeric water quality standards for nutrient pollution. In the
final days of the previous administration, EPA found that nutrient pollution standards are
necessary in Florida after a careful review of existing data and water quality impacts
across the State. The Agency settled a 2008 lawsuit on this issue in August 2009 by
agreeing to adopt numeric nutrient pollution standards by November 2010. Today's rule
complies with the terms of this settlement.

3.	Why did Florida need new standards?

Florida currently has narrative standards for water quality—a verbal description of clean
water conditions. But these narrative standards are general and difficult to apply in
practice. This new rule provides specific measurable guidelines to help restore Florida
lakes, springs, rivers and streams to a healthy condition. Florida waters polluted by
nitrogen and phosphorus will be cleaned up faster and high quality waters will be better
protected from this pollution as a result of these new numeric standards.

4.	What is the timeline for implementation of the standards?

The rule will take effect 15 months after it is published in the Federal Register, except for
the site-specific alternative criteria (SSAC) provision which is effective 60 days from
publication. EPA is extending the effective date for the numeric standards by 15 months
to allow time for the Agency to work with stakeholders and Florida Department of
Environmental Protection (FDEP) to properly implement the rule and to help the public
and all affected parties better understand the final standards and their basis.

5.	How will Floridians benefit from this rule?


-------
Clean and safe waters are central to Florida's prosperity and economic growth. In 2007,
over 4.3 million residents and over 5.8 million visitors participated in recreational
activities in Florida that depend on clean water in streams and lakes. Over 2.7 million
residents and approximately 1 million visitors used freshwater boat ramps, over 3 million
residents and over 900,000 visitors participated in freshwater non-boat fishing, and over
2.6 million residents and almost 1 million visitors participated in canoeing and kayaking.
Many people throughout Florida whose livelihood depends on these recreational water
activities lose income from the impacts of this pollution.

Measurable or "numeric" water quality standards, rather than the narrative standards now
in place, will better protect people's health and aquatic life. Clear, implementable
numeric standards will help improve the quality of rivers, lakes and streams that supply
our drinking water, promote better recreational activities like fishing, boating and
swimming, and support businesses and local economies throughout the state.

6.	Will compliance with this rule hurt Florida's economy?

The tourism industry — Florida's economic lifeblood — depends on clean water and robust
fish populations. In 2010, there were over 80.9 million visitors to the state of Florida,
accounting for an estimated $65 billion in tourism spending. In 2008, tourism spending
resulted in approximately $3.9 billion in State sales tax revenues and contributed to the
employment of more than 1 million Florida residents. More than 880,000 anglers flocked
to Florida in 2006, spending more than $1 billion on fishing related products and services
alone. Combined with residents, Florida's anglers spent more than any other state — $4
billion — making Florida the fishing capital of the nation.

People living near impaired lakes and rivers can see their property values plummet. A
2005 algae outbreak on the St. Lucie River and estuary resulted in a half billion dollar
loss in the county's waterfront property values. Conversely, clean water improves
property values.

EPA believes that businesses and public utilities can readily put in place many low cost
protections needed to meet numeric nutrient pollution standards, and may even save
money over time

7.	How much will it cost to implement this rule?

EPA estimates that the annual cost to address additional waters listed as impaired under
this rule is between $135 and $206 million. This estimate assumes that waste water
treatment plants discharging to impaired inland waters may need to install advanced
treatment (but not reverse osmosis) and that agriculture operations will need to
implement a range of State recommended BMPs to address impaired waters. EPA will
continue to work with the State and stakeholders to determine the most affordable,
common sense methods to plan for and achieve these numeric standards so that Florida's
waters can be restored in the most cost-effective and flexible way possible.


-------
EPA believes that other cost estimates developed by stakeholder groups that contribute to
nitrogen and phosphorus pollution (e.g. municipal utilities, agricultural and industry
groups) substantially overstate both the number of nitrogen and phosphorus pollution
sources that may be affected by this rule, and the types of treatment that these sources
may need to meet the rule.

For example, some stakeholders included in their estimates hundreds of wastewater
treatment facilities not covered by this rule and assumed that all plants across the State
would have to install very expensive additional treatment whether or not they discharge
to impaired waters and regardless of any advanced treatment they may already have in
place. Such estimates also assume that all dischargers will install highly expensive
treatment that the State does not require today even for its most severely impaired waters.
Agricultural estimates have assumed that all 13.6 million acres of agricultural activity in
the State will require treatment even though State data suggests that the more likely
amount is less than 10% of this figure. Where an activity is in an impaired watershed,
EPA has considered only cost-effective BMPs similar to those identified and
recommended by the state.

8.	Will compliance with this rule raise my taxes or utility bills?

This rule will not take effect for another 15 months, and even then implementation will
take place in gradual steps over time. EPA estimates that the annual costs of additional
municipal waste water treatment and urban stormwater BMPs needed as a result of this
rule to address nitrogen and phosphorus is only about a tenth of what some stakeholders
have estimated and will be between $40 to $71 per household per year. This equals 11 to
20 cents per day per household for clean water.

9.	Is this rule based on sound science?

Yes. EPA consulted with scientific experts in Florida and calculated the standards based
on a review of over 13,000 water samples that the State collected from over 2,200 sites
statewide. Consistent with standard EPA practice, the underlying data and methodology
supporting the rule were independently peer reviewed. EPA also solicited extensive
public feedback during the public comment periods following the proposed rule (January
2010) and the supplemental notice of data availability (August 2010). EPA carefully
evaluated the public feedback and changed the rule to reflect the best available science,
such as information on the relationship between nitrogen and phosphorus and biological
responses in lakes and springs, and data on geological formations of phosphorus and least
disturbed stream sites in Florida.

10.	Does this rule require Florida to clean up other states' discharges?

No. In fact, upstream states will be required to ensure the attainment and maintenance of
Florida's numeric nutrient criteria when developing designated uses and water quality
criteria (see 40 CFR 131.10(b)). Numeric water quality standards will create the


-------
structure and framework needed to inform neighboring states of their responsibility to
comply with downstream standards in Florida.

11.	How is EPA working with state officials?

Florida has the primary responsibility for carrying out the requirements of the Clean
Water Act with EPA support and review. Therefore, FDEP is responsible for
implementing the federal numeric standards through their normal regulatory processes, as
they would any other water quality standard. Florida's Department of Environmental
Protection has a commitment to water quality, a high level of scientific expertise and one
of the country's best data bases on the condition of its waters. This data base played a
critical role in shaping the final standards.

EPA and the Florida Department of Environmental Protection share a commitment to
clean water for Florida. EPA has worked closely with state officials to develop a sound
scientific basis for numeric standards over the last 10 years by providing technical
assistance and funding to support sampling and analysis of existing data.

With the promulgation of the numeric criteria in this final rule and the subsequent
development of standards for the estuarine and coastal waters, and south Florida inland
flowing waters (primarily canals) in 2012, we believe Florida will be well-positioned to
carry out their implementation responsibilities. EPA will assist the State in any way
needed to ensure the successful transition to implementation of these standards.

12.	Is Florida the only state that EPA is working with to improve water quality
standards?

Nutrient problems exist in many parts of the United States. EPA has urged every state
and many tribes to adopt specific or "numeric" nutrient pollution standards since 1998.
EPA is targeting its limited resources to help address nutrient pollution where it poses the
greatest threats, including working with states whose waters flow to the Chesapeake Bay,
Long Island Sound, Lake Champlain, the Mississippi River and the Gulf of Mexico.

13.	Is the rulemaking process being rushed?

No. As part of the consent decree with the Florida Wildlife Federation, EPA negotiated a
longer timeline for the development of proposed and final specific or "numeric" nutrient
pollution standards than is provided for under the Clean Water Act. EPA agreed to
establish final numeric nutrient pollution standards for lakes and flowing waters by
November 14, 2010, because EPA was confident it had sound data and scientific methods
to establish appropriate standards in this timeframe.

EPA agreed to issue additional standards for Florida's estuaries and coastal waters by
August 2012 and will shortly be submitting the underlying science for these standards to
its independent Science Advisory Board for peer review.


-------
14.	What is EPA doing to help communities understand and utilize the flexibilities
in the rule?

Over the next 15 months, EPA intends to host webinars and provide technical assistance
and outreach to any community in Florida that wants to understand and utilize the
flexibilities that are built into this rule. EPA will continue to partner with the FDEP, the
scientific community and all stakeholders on the implementation of these new standards.

15.	Why did EPA decide to make the standards effective in 15 months?

We opted for this approach to assure that all stakeholders and the state of Florida have a
full opportunity to review the standards, understand their basis and application, and work
through issues of implementation.

16.	How is EPA responding to the concern that not all water bodies are the same
and case-by-case approaches are needed?

The rule accounted for the differences in Florida rivers and streams by recognizing five
different watershed-based regions for the development of nitrogen and phosphorus
standards. In developing the nutrient criteria for lakes, EPA utilized three lake
classifications based on clarity and alkalinity.

The rule also allows flexible implementation and alternative site-specific criteria where
supported by sound science. These approaches include modifications of lake criteria and
site-specific alternative criteria (SSAC) for both lakes and flowing waters. Site-specific
alternative criteria represent alternative values to the criteria set forth in this final rule that
would be applied on a watershed, area-wide, or waterbody-specific basis. Site-specific
alternative criteria must protect the in-stream designated use, have a basis in sound
science, and ensure the protection and maintenance of downstream water quality
standards. Site-specific alternative criteria may be more or less stringent than the
otherwise applicable federal numeric criteria.

Finally, the state may utilize any of the current mechanisms allowed under the Clean
Water Act that provide flexibility in implementing water quality standards, such as
variances and compliance schedules, if additional time is needed to meet the new criteria.

Section V of the preamble to the final rule provides more detail about the requirements
for pursuing any of the options for modification, and describes when the utilization of a
given approach would be most appropriate.

17.	How will the rule affect Total Maximum Daily Loads (TMDLs) on the books
that were developed by the state of Florida and previously approved by EPA?

No TMDL will be rescinded or invalidated as a result of this final rule nor does this final
rule have the effect of withdrawing any prior EPA approval of a TMDL in Florida.


-------
Nutrient TMDLs which were established prior to the effective date of the new criteria
will stay in effect until updated and reviewed for consistency with applicable water
quality criteria or changed waterbody conditions as part of the State's normal assessment,
listing, and TMDL review process.

In certain situations affecting local governments or businesses where substantial
investments in pollution control are predicated on water quality based effluent limits, and
there is a need for long term planning certainty in making and maintaining these
investments, this rule specifically establishes a federal SSAC process that allows the
expeditious review of present TMDL targets and an evaluation of whether those targets
represent appropriate site-specific alternative criteria in place of the numeric values in
today's rule.

Florida or any other entity may initiate a SSAC process to review the water quality
targets of existing TMDLs as site-specific alternative criteria. Site-specific alternative
criteria represent alternative values to the new criteria that would be applied on a
watershed, area-wide, or waterbody-specific basis. Regulations require that site-specific
alternative criteria protect the in-stream designated use, have a basis in sound science,
and ensure the protection and maintenance of downstream water quality standards. Site-
specific alternative criteria may be more or less stringent than the otherwise applicable
federal numeric criteria. By law, EPA must evaluate the technical basis and
protectiveness of any proposed site-specific alternative criteria and will take action after
appropriate public involvement.

18.	How will these new standards affect existing NPDES permits?

NPDES permits are subject to five year cycles and in certain circumstances are
administratively continued beyond five years. When a permit is renewed, it must comply
both with applicable TMDL requirements and any new applicable criteria that may have
been established since the TMDL was developed.

19.	How will this new rule affect agricultural activities in the state of Florida?

Most agricultural activities are not directly regulated under the Clean Water Act. For
these activities, this new rule may affect them if they are located near waters that may be
identified as impaired under this rule, i.e., waters that do not meet the new criteria. For
agricultural operations in these areas, FDEP and the Florida Department of Agriculture
and Consumer Services may require additional nonpoint source control procedures to
limit runoff of fertilizers and animal wastes, i.e., best management practices (BMPs) in
order to attain the numeric nutrient criteria that support state-designated uses.

However, Concentrated Animal Feeding Operations (CAFOs) are regulated under CWA
Section 402 and as such may require NPDES (National Pollutant Discharge Elimination
System) permits with water quality based effluent limits (WQBELs) for discharges.

Since NPDES permits must be written to meet water quality standards, these permits may
need to be revised based on the new numeric nutrient criteria. EPA is not aware of any


-------
other agricultural activities regulated under CWA Section 402 that will be impacted by
the final rule.

20.	How do the final standards compare with the draft standards previously
developed by the State of Florida?

Today's final criteria are very similar to the draft standards previously developed by the
State of Florida and reflect the same body of science, data, and methodologies that
Florida considered.

21.	How has EPA responded to criticism that its Downstream Protection Values
(DPVs) are overly conservative and very burdensome on upstream dischargers?

EPA has carefully considered many comments on this issue. In response to our request
for comment on the most appropriate model to use for calculating DPVs, the rule has
been significantly revised to utilize a different primary model and allow the use of other
scientifically comparable modeling approaches. The final rule also allows several
alternative approaches to developing a DPV and determining the most appropriate point
of compliance

The DPVs for estuaries and coastal waters will be finalized in August 2012. These
values will apply after the effective date of the 2012 rule and as permits come up for
renewal.

22.	In what specific ways has EPA modified the final standards to take into account
scientific concerns raised by the state of Florida and others?

Throughout the rule-making process, stakeholders and FDEP raised a number of concerns
about the science and ability to flexibly implement certain provisions in the rule.

EPA listened carefully and was responsive to these concerns by:

1)	Delaying finalization of downstream protection values (DPVs) for estuaries and
criteria for South Florida canals to allow for additional review by EPA's Science
Advisory Board

2)	Finalizing criteria for Florida's streams that account for geological differences
across the State

3)	Acting upon and adopting significant elements of FDEP's least-disturbed stream
site Benchmark approach

4)	Finalizing adjustable criteria for Florida's lakes that account for site-specific data

5)	Finalizing a criterion for Florida's springs that matches the criterion FDEP
proposed as appropriate

6)	Establishing a procedure for deriving federal SSACs where site-specific technical
and science data support the need for refinements to the federal criteria


-------
7)	Providing substantially more flexibility in the development and implementation of
lake down stream protection values

8)	Adding a 15 month effective date

23.	What will the immediate impact of the standards be when they take effect after
15 months?

Once the new standards become effective, implementation will be phased in as water
quality assessments are completed and impaired waters are identified; total maximum
daily loads are calculated and implemented; and NPDES permits are renewed. In each of
these processes there are opportunities for public participation and further scientific and
technical analysis. As a delegated State, the Florida Department of Environmental
Protection has the primary responsibility of setting priorities and carrying out these
actions with oversight and assistance from EPA. Where streams, lakes, or springs do not
achieve the numeric standards, point source dischargers of nitrogen or phosphorous will
need new or revised NPDES permit conditions. Other sources such as agriculture and/or
septic systems will have to apply nitrogen and phosphorus pollution Best Management
Practices as developed through TMDLs, Basin Management Action Plans and related
State requirements.

24.	What role will the state of Florida play in implementation?

Florida has the primary responsibility of carrying out the requirements of the Clean
Water Act and will be responsible for implementing the numeric standards through their
normal water quality program and associated regulatory processes, as with any other
water quality standard.

25.	How does EPA plan to address nutrient pollution of estuarine and coastal areas?

EPA plans to propose numeric nutrient criteria for Florida's estuarine, coastal waters and
Southern Florida inland flowing waters by November 14, 2011 and will sign the final rule
by August 15, 2012. EPA will shortly be submitting the underlying science for these
standards to its independent Science Advisory Board for peer review.

26.	What role will the state of Florida play in developing standards for estuaries and
coastal areas?

EPA has been working with FDEP scientists and technical staff on this effort since
February 2009, and we will continue to work closely on development of the estuary and
coastal numeric nutrient criteria.
