DREWRYVILLE FAS SHOP

Ammonia violation at Capron school plant doubles with no oxygen data to check it

The wastewater facility serving Capron Town-Elementary School has crossed into Significant Non-Compliance, the most serious tier EPA uses for permit violations. The label matters less than the trend behind it: the ammonia overage stood at 42 percent above the permitted limit last fall and had climbed to 95 percent above limit by the quarter ending this March, doubling in a single reporting period with no sign of correction since. Of the 16 permitted dischargers tracked in this watershed, only this facility and the Drewryville FAS Shop now carry that designation, and total penalties assessed across the entire watershed add up to just $3,762, a figure that sits oddly small next to a violation of this scale. What makes the timing worse is what isn't being measured. The Nottoway and Meherrin river gauges nearby track streamflow and gage height, but none of them measure dissolved oxygen, temperature, or pH. That means an escalating ammonia discharge is entering Three Creek and the Meherrin River corridor, a system that already carries failing water-quality grades from earlier assessment, with no independent way to check whether oxygen levels are actually being driven down. Ammonia at high concentration is directly toxic to fish and invertebrates, and its breakdown in the water column consumes dissolved oxygen, exactly the resource that blackwater streams in the Rolling Coastal Plain have little buffering capacity to spare once August heat sets in. Whether that depletion is happening right now is not something the current monitoring network can answer, which is its own kind of warning.
