# AVAIO Project Leo Construction Stormwater Permit Modification Native DEQ Office of Water Quality correspondence showing that [[AVAIO Digital Partners|AVAIO]] / [[ADP Little Rock Data Hub, LLC]] filed a **modification** to its Project Leo construction-stormwater coverage (NOI under Construction General Permit `ARR150000`; submission `HQN-AP0Z-K08T3`) in spring 2026. Files: `Construction Permit Modification-HQN-AP0Z-K08T3 - AVAIO Little Rock.msg`, `FW_ CONSTRUCTION STORMWATER GENERAL PERMIT (CGP) NUMBER ARR150000.msg`, `FW_ Water - Construction Stormwater General Permit (ARR150000) - Modification - Submission ID HQD-1ZD4-NKZ5R.msg`. ## Key takeaways - **Kimley-Horn fronts the AVAIO water permitting.** Nate Bachelor, PE (Kimley-Horn, Rogers AR office) chases DEQ on the modification: "I wanted to ask if you are assigned the review for the modification we submitted on the AVAIO Little Rock project ... This one was submitted on **5/8/26** and the signed RO form was delivered the following week" (`Construction Permit Modification-HQN-AP0Z-K08T3 - AVAIO Little Rock.msg`, Jun 1 2026). DEQ engineers Nghi ("Sally") Ngo and **Kaile Johnson** (Water Quality) handle the routing; as of Jun 1 2026 it was in management review. - This is a **post-construction modification** to the only Project Leo environmental coverage the corpus has documented — construction stormwater — consistent with the earlier finding that AVAIO/Leo holds no air permit and (publicly) only stormwater coverage. It places active AVAIO water-permit activity in **May–June 2026**, contemporaneous with this FOIA campaign. ## People and orgs mentioned - [[Nate Bachelor]] — Kimley-Horn (Rogers, AR), PE; AVAIO's water-permit agent. (DEQ: Kaile Johnson, engineer; Nghi "Sally" Ngo, engineer — Water Quality.) - [[Kimley-Horn]] · [[AVAIO Digital Partners]] · [[ADP Little Rock Data Hub, LLC]] ## Cross-references - [[county-pulaski/project-leo-2026-05-22/_overview]] — the Project Leo planning file. - [[Groot STAA Signatory and Section 401 Gating Correspondence]] — Kimley-Horn also fronts Groot/Pyramid (shared-vendor channel). ## Open questions / follow-ups - What the modification changes (acreage, operator, BMPs) is not stated in the cover correspondence; the underlying NOI/modification forms were not produced in native form here.
