Who is affected and how:

• Farmers and land managers: Directly affected because research could change best practices for applying biosolids, identify risks to soils or crops, and lead to new guidance or restrictions in the future. Short-term impact is increased access to extension information; long-term impact depends on research results.
• Wastewater treatment facilities and biosolids producers/operators (including publicly owned treatment works): May be engaged as research partners and could face incentives or technical support to adopt treatment improvements that reduce microplastic loads.
• Scientific and extension communities (universities, research institutions, Cooperative Extension): Gain grant opportunities to study measurement, treatment, and agronomic impacts; likely to develop standardized methods and outreach materials.
• Local communities and rural residents near fields where biosolids are applied: Stand to benefit from better data on exposure pathways and environmental impacts; possible indirect impacts if research prompts changes in application practices.
• Federal agencies and regulators (USDA and partners): Will administer grants and may use results to inform guidance, monitoring, or regulatory proposals. However, Section 2’s struck-and-replaced statutory language introduces uncertainty until the new text is available—this could alter program administration, eligibility, or reporting obligations tied to the biosolids authorities.

Overall, the bill primarily funds and directs research and outreach rather than imposing immediate regulatory controls; any regulatory or compliance impacts would follow from subsequent findings and policy decisions. The unspecified statutory replacements in Section 2 create a degree of legal and administrative uncertainty until the new text is known.
