Vale Wood Farms exceeds its BOD limit a second quarter running
August 19, 2026
An update, and a correction, on a finding from earlier this summer: on July 14, this feed reported that Vale Wood Farms Dairy in Loretto, PA, had discharged wastewater above its permitted level in early spring. That report described the overage as "nearly double." The underlying record is worse than that. At outfall 001 in the quarter ending March 31, five-day BOD came in 183% over the monthly-average permit limit — close to three times what the permit allows — while total suspended solids ran 55% over. Two very different numbers, and averaging them into one rounded phrase undersold the oxygen-demanding half of the discharge.EPA's compliance database now also carries a formal Significant Non-Compliance designation for the facility, coded as an effluent violation on a monthly average. And the spring quarter is no longer alone: a second set of exceedances at the same outfall, dated August 14, puts BOD 144% over the limit and TSS 92% over. BOD has eased somewhat but is still more than double the permitted level, and suspended solids have gotten worse, not better. This is a documented pattern across two monitoring quarters rather than an inference drawn from the non-compliance flag.The timing works against the stream. Cold spring runoff can hold roughly 12 to 13 milligrams per liter of dissolved oxygen at saturation; by late August, water near 25 °C holds closer to 8. That is a meaningful loss of margin, and it is exactly when organic-rich, oxygen-demanding discharge is landing. What we cannot say is what it has actually done downstream — no in-stream dissolved oxygen reading is available near the outfall, so the ecological consequence remains unmeasured. The regulatory trajectory is the documented part: a spring exceedance, an active non-compliance finding, and a second quarter of exceedances in the low-oxygen heart of summer.A problem that might have resolved on its own instead persisted through the season when it counts most. That pattern is worth watching alongside the work of local groups such as the Clearfield Creek Watershed Association and the Chest Creek Watershed Alliance, both of which monitor water quality in this part of the Central Appalachians' upland dairy country.
Chimney swifts over the early summer emergence
June 25, 2026
Look up. Over the open ground at SGL 198, chimney swifts are cutting arcs across the sky, chattering as they go. That high, thin chipping call is almost continuous when a group is working the air above a field or water. The birds themselves are small and dark, with a stiff, flickering wingbeat unlike any swallow — they look as though they are beating both wings alternately rather than together, though they are not. What they are doing up there, right now, is feeding. And what they are feeding on is the early summer emergence of aquatic insects.Mayflies and caddisflies spend most of their lives underwater. Mayfly nymphs live in stream gravel and leaf litter for months, sometimes more than a year, grazing on algae and organic debris. Caddisfly larvae build cases from sand grains or plant fragments and do the same. Then, in early summer, they transform and leave the water. Mayflies emerge as winged adults that cannot feed at all — their mouthparts are vestigial, their digestive systems reduced. They have hours or days to find a mate and deposit eggs before they die. Caddisflies live a little longer as adults but are similarly driven by the narrow window of their emergence. Both emerge in large numbers over short periods, which concentrates them in the air above streams and ponds at predictable times. Chimney swifts find them there.A swift forages entirely on the wing. It drinks on the wing, skimming a water surface. It collects nesting material on the wing, snapping dead twigs from treetops as it passes. During nesting season, the adults must catch enough insects not only to sustain themselves but to carry back to nestlings in whatever chimney or hollow tree they have claimed. Swifts compress multiple insects into a mass in their throat pouch before returning to the nest. A single feeding trip can deliver dozens of small insects at once. The aquatic emergence matters because it produces exactly what the birds need: large numbers of soft-bodied, protein-rich insects concentrated in open airspace over water, reliably, at the time of year when nestlings are growing fastest.The swifts at SGL 198 are working the open fields and edges near the strip mine areas, which likely drain into small streams and wet areas. Those drainages, even modest ones, produce mayflies and caddisflies. The birds range widely from their nest sites — several kilometers is unremarkable — so a swift nesting in a chimney in Ashville may be foraging over water a mile or more away. Other aerial insectivores are doing the same thing. Eastern phoebes and eastern wood-pewees are both present here, taking insects in sallying flights from exposed perches at the forest edge. They are working a different layer of the same emergence, catching insects closer to vegetation rather than high in open air. The resource is large enough that the birds partition it by flight style and hunting height without much direct competition.

Among thirty water bodies surveyed in the region, Glendale Lake stands alone as officially impaired — a designation that carries weight in a landscape where the other waters remain in compliance. The lake requires a restoration plan under federal law, yet the source of its decline is neither mysterious nor distant.A dairy operation upstream exceeded its organic waste limit by 183 percent in early 2026, the kind of overage that typically worsens when summer heat arrives and water levels drop. With the surrounding landscape still 74% forested—a reminder that this was forest country not long ago—the remaining 17% in active agriculture now concentrates enough pressure to impair the only failing lake in the survey. The failure names precisely where the agricultural margin has narrowed: not across the whole ecoregion, but in one drainage where a single facility's permitted capacity cannot absorb the load it generates.
