This report provides an overview of EPA's Bioassessment & Biocriteria Program, including project background, goals, survey development, and assessment findings. The report highlights the mission of the program, which is to accelerate the adoption of biocriteria into water quality standards by all States/Tribes, and discusses the progress made in biocriteria development for various water bodies. It also includes information on the use of bioassessments within water quality programs and for decision-making regarding aquatic life use.

Summary of Biological Assessment Programs and Biocriteria Development for States, Tribes, Territories, and Interstate Commissions: Streams and Wadeable Rivers2001 Program Update(EPA-822-R-02-048) Beth Jackson USEPA Office of Environmental Information December 9, 2002
Highlights • Overview of EPA’s Bioassessment & Biocriteria Program • Project Background & Goals • Survey Development • Information Collection & Assessment • Findings
EPA’s Biological Assessment and Criteria Program Strategy Program Mission: Accelerate adoption of biocriteria into water quality standards by all States/Tribes Mission: FY 2002- 2005 To better protect aquatic life through the integration of biologically-based assessments and standards into State and Tribal water quality programs
The Biological Assessment and Criteria Program • Support successful adoption of biocriteria for streams and rivers (in WQS) by all States and Authorized Tribes • Start to implement biocriteria for Lakes and Reservoirs • Introduce biocriteria for Estuaries and Coastal Waters • Make progress on biocriteria methods for other water bodies
Background • Launched effort to update and expand the 1996 summary document (EPA 230-R-96-007) in June 2001 • Supported by EPA’s Biocriteria Team (OW, ORD, OEI, Regional Biocriteria Coordinators) • Expanded to include detailed information on: • use of bioassessments within water quality programs; and • use for Aquatic Life Use decision-making • Expanded coverage to include federally recognized Tribes, more US territories & Interstate Basin Commissions
Project Goals • Determine bioassessment capacity for • determining ALU support, • water quality decision-making (305(b) reporting and 303(d) listings), • developing TMDLs • Determine progress made in biocriteria development • Illustrate changes and improvements in bioassessment capabilities over the past 5 years
Project Goals, continued • Provide an important measure of State/Tribal program advancement and EPA’s technical transfer efforts • Allow EPA Biocriteria Team to better focus its WQS and Criteria Strategy • Assess technical support needs of States/Tribes
Survey Development • Developed 57 question survey • Received input from OWOW, OST, OEI, EPA Regions, Midwest Biodiversity Institute, contractor • Addressed 5 critical areas: 1. Programmatic Elements 2. Aquatic Life Use for Decision-Making 3. Field and Lab Methods 4. Data Analysis and Interpretation Procedures 5. Information Management
Information Collection & Assessment • Distributed over 75 surveys to States Tribes, Territories and Interstate Basin Commissions • Conducted follow-up interviews with responding entities • Followed extensive QA/QC to ensure accuracy and quality of responses
Findings • 65 entities responded • 57 entities have bioassessment programs featured in report • 40 entities use bioassessments to determine ALU • ~ 475,000 river and streams miles assessed using bioassessments
Assemblages Used: Benthic Macroinvertebrates 56 in place 1 under development
Assemblages Used: Fish 41 in place 16 none
Assemblages Used: Periphyton 21 in place 4 under development 32 none
Use of Multiple Assemblages 45 more than 1 assemblage
Progress Made Since 1995 • 30 entities have Narrative Biocriteria (in WQS): increased by 1 • 4 entities have Numeric Biocriteria:; increased by 2 • Assemblages: • 12 more entities using Fish • 12 more entities using Macroinvertebrates • 17 more using Algae • 19 more using more than 1 assemblage
