Answers and Password

  1. True or False Statement: A State/Tribe can establish one set of water quality criteria for all of its water bodies.

    Answer: The answer is True if the criteria will support protection of the designated uses for those water bodies. However, increasingly EPA advises States and Tribes to pay close attention to establishing criteria that are appropriate for specific types of water bodies or designated uses to eliminate the potential for over protective criteria.

  2. How often is a State/Tribe expected to revise its criteria?

    Answer: As necessary. The answer is as necessary when new scientific data or methodologies are developed. However, States/Tribes are required by the CWA to review their water quality standards at least every 3 years.

  3. True or False Statement: Where any of the “priority pollutants” identified by EPA are a concern for a particular water body, the State/Tribe must adopt EPA’s criteria for that pollutant.

    Answer: False. While the State/Tribe in such cases must adopt criteria for the pollutant, EPA's criteria solely provide guidance and the State/Tribe may use alternatives if they are scientifically defensible and protect the designated use.

  4. Which of the six criteria types always takes precedence over the others?

    Answer: None of the above (human health, bacteriological, aquatic life, sediment, biological, nutrient). Each criteria should be independently applied, with the one protecting the most sensitive waterbody designated use taking precedence.

  5. True or False Statement: EPA’s water quality criteria carry the weight of law and are enforceable.

    Answer: False. No criteria have the force of law until they have been adopted into the particular State or Tribe's water quality standards, EPA has approved them, and they are implemented in a regulatory tool (e.g., an NPDES permit).
