# EPA Envirofacts + USGS Water — Arkansas data-center water-facet capture (2026-06-04) > *Authoritative agency-API outputs captured 2026-06-04 via the epa-envirofacts and usgs-water MCP connectors. The saved `original_file` is the JSON capture of the query results.* ## Extract ### EPA Envirofacts — Tupelo Bayou WWTP (the Project Stratus cooling-water source) - **FRS Registry ID 110043640432**, "TUPELO BAYOU WWTP," 1405 Lollie Rd, Conway, AR 72034. Programs: **FRS only**; **zero RCRA or TRI compliance/violation records** over the 5-year window. - **Boundary finding**: Envirofacts does not cover NPDES water-discharge compliance, so the WWTP's effluent permit (**AR0051951**) status and DMRs are **not** retrievable here — they require EPA ECHO/ICIS. (ECHO direct API returned HTTP 429 rate-limiting and robots.txt blocking on 2026-06-04 — see Open gaps.) ### EPA Envirofacts — Conway / Project Stratus vicinity - The site (geocoded to 35.057082, -92.534682) has **50 FRS-registered facilities within a 2-mile radius**. (The tool's accompanying public-water-system list appears loosely matched — it includes systems far from Conway — and is therefore not cited as site-proximate.) ### USGS Water — Arkansas River and Faulkner-County groundwater - **Gage USGS-07263285**, "ARK.RIV AT RIVER MILE 133 NR. MAUMELLE, AR." (Pulaski County; HUC 111102070107; stream; altitude 250 ft NGVD29; lat/long 34.8548, -92.4554) — the Arkansas River reach that is the receiving water for the Tupelo Bayou treated-effluent discharge and the river adjacent to the Little Rock-area sites. Its real-time (IV) discharge/gage-height series returned **empty** on 2026-06-04 (no current published real-time values for parameters 00060/00065). - **Faulkner-County groundwater monitoring network**: 30+ GW wells operated by the Arkansas Department of Health (agency code AR001) and the Arkansas Natural Resources Commission (AR008); observed aquifer codes include 326ATOK (Atoka) and 110ALVM (alluvium), with many null. The **Sparta aquifer (124SPRT)** was not flagged in the first 30 Faulkner records. ## Notes - **Tier 2** — primary agency data (federal FRS/EPA + USGS). It corroborates facility identity and the regional water-monitoring context; it does **not** establish what any Arkansas actor did with the water (those are the Tier-1 Conway Corp / Agriculture productions already in the corpus). - **Open gaps** (each with its next step): - **NPDES AR0051951 status + DMRs** — blocked this pass (ECHO 429/robots). Next: EPA ECHO detailed-facility report via Firecrawl, or the ECHO REST API after the rate-limit window; or the Arkansas DEE/DEQ NPDES file (FOIA). - **Sparta Aquifer (124SPRT) multi-year drawdown** — not isolated this pass; the OGC well list did not expose a Sparta-coded observation well in Faulkner. Next: query NWIS GW-levels/DV service (`waterservices.usgs.gov/nwis/gwlevels`) for a 124SPRT-coded well in the relevant county, or the USGS Arkansas Water Science Center Sparta potentiometric-surface reports. - **Project Leo cooling-water source** — still unnamed in the federal/USACE package (see [[Identifying the Unnamed Cooling-Water Data Centers]]). - Cited by: [[Tupelo Bayou Treated-Effluent Cooling]]; [[Sparta Aquifer]]; [[Identifying the Unnamed Cooling-Water Data Centers]].
