  "description": "Status of EPA risk management rules for chemicals found to present unreasonable risk under TSCA Section 6. Each record is one chemical with its current rule status (proposed/final/effective), effective dates for prohibitions, specific uses prohibited, and any exemptions or compliance date extensions. Currently covers ~11 chemicals under Section 6(a) active risk management plus 5 PBT chemicals under Section 6(h). The pipeline has 20+ more chemicals in risk evaluation. Answers 'is [chemical] being regulated under TSCA?', 'when does the prohibition on methylene chloride take effect?', 'which uses of TCE are exempt?', and 'what is the current rule status for 1-bromopropane?'",
