II. Background

    Section 304(a)(1) of the Clean Water Act (CWA) requires EPA to 
develop, publish, and from time to time, revise criteria for water 
quality accurately reflecting the latest scientific knowledge. Water 
quality criteria are scientifically derived numeric values that measure 
the level beyond which pollutants in ambient water will have 
deleterious effects on aquatic life or human health. Water quality 
criteria developed under Section 304(a) are based solely on data and 
scientific judgments on the relationship between pollutant 
concentrations and environmental and human health effects. Section 
304(a) criteria do not reflect consideration of economic impacts or the 
technological feasibility of meeting the chemical concentrations in 
ambient water.
    Section 304(a) criteria provide guidance to states and authorized 
tribes in adopting water quality standards that ultimately provide the 
basis for controlling discharges or releases of pollutants. The 
criteria also provide guidance to EPA when promulgating Federal 
regulations under Section 303(c) when such action is necessary. Under 
the CWA and its implementing regulations, states and authorized tribes 
adopt water quality criteria to measure attainment of designated uses 
(e.g., public water supply, recreational use, industrial use). EPA's 
recommended criteria do not impose legally binding requirements. States 
and authorized tribes have the discretion to adopt, where appropriate, 
other scientifically defensible water quality criteria that differ from 
EPA's recommended criteria.
    FIFRA requires that all pesticides used in the United States be 
registered by EPA for use and, thus, ensures Federal control of 
distribution, sale, and use of pesticides. Registration assures that 
pesticides will be properly labeled and that, if used in accordance 
with labeled specifications, will not cause unreasonable adverse 
effects on human health and the environment. FIFRA ecological risk 
assessments quantitatively evaluate reduced survival of aquatic animals 
from direct acute exposures and survival, growth, and reproductive 
impairment for aquatic animals from direct chronic exposures. 
Assessments for aquatic plants focus on growth rates and biomass 
(reproduction) measurements. Risk management decisions for pesticide 
registration under FIFRA take into consideration benefits in addition 
to risks of pesticides used; however, benefits are not considered in 
characterizing ecological effects under FIFRA or in deriving ambient 
water quality criteria (AWQC) values under CWA.
    For FIFRA ecological effects assessments, EPA peer reviews toxicity 
data provided by the registrant as required by regulation, as well as 
data from public sources obtained from EPA's ECOTOX database. Current 
testing requirements for aquatic organisms include toxicity studies 
containing information on survival, reproduction, and growth endpoints 
for freshwater and estuarine/marine animals and biomass and growth 
endpoints for aquatic plants. These test requirements are defined for 
each chemical class by use category in title 40 of the Code of Federal 
Regulations, part 158. Studies are performed on laboratory test 
organisms in the following broad taxonomic groupings: freshwater fish 
and invertebrates, estuarine/marine fish and invertebrates, and aquatic 
plants. For screening-level assessments, OPP's effects assessments are 
based on the lowest acute and chronic toxicity values from the most 
sensitive species tested in acceptable studies. More refined 
assessments may use the full species sensitivity distribution for a 
given taxa or other toxicity endpoints, as for the variability and 
uncertainty of the data (probabilistic approaches). The ``OPP Aquatic 
Benchmarks'' is a web site developed by OPP that contains the aquatic 
toxicity endpoints used in EPA pesticide risk assessments. (http://
www.epa.gov/oppefed1/ecorisk_ders/aquatic_life_benchmarks.htm).
    Although both OPP's and OW's approaches afford a high degree of 
protection for aquatic life, stakeholders have identified a need for 
consistent and timely Federal input that will allow EPA, states, 
tribes, and the public to gauge whether pesticides represent a concern 
for aquatic life, for example, based on water monitoring results. To 
address these concerns, the Agency has begun a process to explore how 
to build on the high quality science in both OW and OPP to develop 
additional tools and approaches to support a consistent and common set 
of effects characterization methods using best available information. A 
Scoping Document has been developed that describes this effort in more 
detail. A letter signed by the Office Directors of OPP and OW, and 
reinforced by the Scoping Document, has invited public participation in 
our collective efforts. Following through on this invitation, regional 
public meetings are being planned for January 2010 to solicit input on 
the Agency's initial thinking regarding methods, tools, and approaches 
that are being developed and evaluated by OPP and OW, with the support 
of ORD, to assure that pesticide ecological effects are characterized 
consistently. The areas for consideration under this effort include:
     Development and evaluation of predictive tools for use in 
development of community level benchmarks
     Development of aquatic life community level benchmarks 
with datasets that do not conform to the ``1985 Guidelines''
     Derivation of aquatic life screening values for aquatic 
plants
    The tools and approaches developed by EPA will:
     Continue to be based upon sound science and utilize the 
available data,
     Be legally defensible under our statutory mandates,
     Be based upon methodologies that are as consistent and 
practical as possible,
     Be implementable at the Federal and State level.
     Be developed as quickly and efficiently as possible, and
     Reflect stakeholder input and comments.

[[Page 61681]]

    During these meetings, EPA will also solicit input from Regional 
stakeholders regarding the following:
    1. Additional sources of pesticide data and relevant reports.
    2. The white paper topics.
    3. The availability of data, tools, approaches, and data sets on 
aquatic toxicity that may be useful for this effort.
    4. The types of values that are used by states and/or regions for 
protecting aquatic life in the absence of ambient water quality 
criteria.
    5. Examples of situations in which differences between OW and OPP 
assessment approaches were an issue.
    Following these meetings, the Agency plans to develop a set of 
white papers, describing potential new tools and analytical approaches 
that may be used by the Agency, state pesticide and water quality 
agencies, and other stakeholders.

risk assessments (http://www.epa.gov/oppfead1/endanger/consultation/
ecorisk-overview.pdf). The data requirements for aquatic non-target 
plants and animals for pesticides are described in title 40 of the Code 
of Federal Regulations, revised July 1, 2008 (Sec.  158.660 Non-target 
Plant Protection Data Requirements). The required procedures for 
conducting the studies are described in OPPTS Harmonized Test 
Guidelines Series 850 ``Ecological Effects Test Guidelines - Public 
Drafts'' (http://www.epa.gov/opptsfrs/publications/OPPTS_Harmonized/

procedures used to evaluate these studies are described in: Standard 
Evaluation Protocols, the guidance document entitled ``the Rejection 
Rate Analysis: Ecological Effects'' (EPA 738-R-94-035), and in the OPP 
Overview Document. Public literature is accessed by OPP through EPA's 
ECOTOX database (http://cfpub.epa.gov.ecotox/). The ``OPP Aquatic 
Benchmarks,'' a web site developed by OPP, contains the aquatic 
toxicity endpoints used in pesticide assessments (Http://www.epa.gov/
