305 Ga. 799
Ga.2019Background
- The City of Guyton obtained an EPD permit (2013) to build and operate a land application system (LAS) that applies treated wastewater to land via spray irrigation; the permit included conservative operational limits, monitoring, buffers, and watershed protections.
- Craig Barrow, owner of adjacent property, challenged the permit, asserting among other things that EPD failed to perform a required antidegradation analysis under Ga. Comp. R. & Regs. r. 391-3-6-.03(2)(b)(ii).
- An ALJ and the superior court upheld the permit, reasoning the LAS was a nonpoint source and the antidegradation rule applied only to point sources.
- The Court of Appeals reversed, reading the antidegradation rule’s text to require an antidegradation analysis for any permit authorizing lowered water quality, including nonpoint sources, and rejecting EPD’s internal interpretation.
- The Georgia Supreme Court granted certiorari to address (1) whether courts should defer to EPD’s interpretation of its regulation and (2) whether the antidegradation rule requires analysis for nonpoint sources; it concluded deference need not be resolved because the regulation is unambiguous in context.
Issues
| Issue | Plaintiff's Argument (Barrow) | Defendant's Argument (City/EPD) | Held |
|---|---|---|---|
| Whether the antidegradation rule requires an antidegradation analysis before issuing a permit for a nonpoint source LAS | The rule’s plain text addresses both point and nonpoint sources and therefore requires an antidegradation analysis for any permit that lowers water quality | The rule, read in its statutory and regulatory context (including the CWA/NPDES framework), applies to point sources; for nonpoint sources the rule only requires implementation of cost-effective best management practices | The Court held the antidegradation rule does not require an antidegradation analysis for nonpoint sources (including LASs) and reversed the Court of Appeals |
| Whether courts must defer to EPD’s interpretation of its own regulation (Auer-type deference) | Barrow argued the Court of Appeals properly rejected EPD’s contrary interpretation of the regulation | City/EPD urged judicial deference to the agency’s interpretation of its own regulation | The Court did not decide the deference issue because it found the regulation unambiguous in its legal context; deference question unnecessary to resolve |
