The Illinois EPA environmental-justice notification letter for the project states the address and describes the scope as a new data center with 126 diesel emergency generators.
Key data: 2000 Landmeier Road, Elk Grove Village; 126 × 2.5 MW diesel emergency generators; BOA ID 031440AWO, application 25120023
Limitation: No PIN/parcel number stated; no coordinates.
The IEPA letter names the applicant only as "Stream ORD" with contact Emily Weissinger. Stream Data Centers' own locations page lists its Chicago portfolio including 2000 Landmeier Road (ORDC) and names holding entities for its other Chicago sites.
Key data: Applicant "Stream ORD" (contact Emily Weissinger); Stream entities SDC CHI I LLC and SDC CHI II BUSSE LLC used for sibling sites
Limitation: The specific holding LLC for 2000 Landmeier was not identified; Cook County PIN/deed lookup not accessible.
Stream's Chicago locations page identifies ComEd as the utility for its Chicago-area campuses.
Key data: ComEd
Limitation: No interconnection agreement or large-load contract reference published; the IEPA letter does not name a utility.
The IEPA notification letter enumerates the full governmental stack notified for the permit, spanning village, county, state and federal layers plus a stormwater special district.
Key data: Elk Grove Village; Cook County (Dept. of Environment & Sustainability, Board of Commissioners, Facilities Management); Illinois EPA Bureau of Air; IDOT; Lake County Stormwater Management Commission; U.S. Army Corps of Engineers; State Senate 28 / State Rep 56 / U.S. Congressional 3
Limitation: The distribution list mixes standard recipients; Lake County SMC inclusion appears to be boilerplate rather than jurisdictional.
Key data: 126 diesel emergency generators at 2.5 MW each
Status date: n.a. (letter carries no date in the fetched text; filed under the agency's 2026 notification-letter folder)
Limitation: No date, total MW, or square footage in the letter. Application number prefix (2512) implies a December 2025 receipt but the letter does not say so.
Illinois EPA formally designated the Stream ORD site as an EJ area of concern via its EJ Start tool and issued an EJ notification letter for the construction permit application, which covers an unusually large diesel generator fleet.
Key data: Permit application 25120023, BOA ID 031440AWO; **126 diesel generators at 2.5 MW each**; site designated EJ area
Status date: 2026
Limitation: The letter states the screening criterion (block groups at or above the statewide average for low-income and/or minority population) but contains **no numeric percentages**.
Independent EJScreen screening of the Stream ORD block group returns the highest EJ-index percentiles of any Illinois anchor site, consistent with Illinois EPA's EJ designation.
Key data: BG 170317704001: 34.6% people of color, $87,917 median HH income; US EJ-index pctiles PM2.5 68 / diesel 71 / RSEI-air 77 / ozone 75 / traffic 68 / NO2 72; state PM2.5 pctile 58
Status date: 2026-08-29
Limitation: Coordinates approximated; EJ-index (D2) percentiles.
