Bill Summary · SB 664

Legislative bill overview

SB 664 expands Tennessee's aquatic resource alteration permit exemptions from wetlands to all types of aquatic resources. It requires the Department of Environment and Conservation to exempt permit applicants from compensatory mitigation requirements when the only reason they don't qualify for a general permit is the size of the affected area.

Why is this important

This bill affects environmental compliance costs for developers, construction companies, and landowners undertaking projects near water bodies. It could reduce mitigation requirements and associated expenses for projects that exceed general permit size thresholds, while potentially reducing environmental restoration obligations.

Potential points of contention

  • Environmental protection vs. regulatory burden: Reducing mitigation requirements may lower environmental restoration efforts while easing compliance costs for project developers
  • Scope expansion concerns: Broadening exemptions from wetlands-only to all aquatic resources could significantly expand the number of affected projects and their environmental footprint
  • Implementation ambiguity: The bill's language regarding "equal in size" exemptions may create enforcement questions about how much mitigation is actually required versus waived
