What this page shows

The SALT RIVER PROJECT - AGUA FRIA GENERATING STATION general permit coverage in Glendale is one of 350 general permit coverages in Maricopa County on EPA's NPDES register, and it sits among 79 NPDES permits in the City of Peoria-New River subwatershed. Of the 350 Maricopa County general permit coverages, 80.9% were issued earlier than this one, and none of them with a violation on file carry a 0.0% share, so this permit's record matches that peer group on that measure.
