The assessor's comments
Sallow Creek, perennial, flows through the middle of the Project Area for about 6,850 linear feet. Five wetlands delineated, including Category 3 wetland W-3. Draft layout avoids wetlands; HDD planned for creek crossings and one ephemeral crossing under Nationwide Permit 14. ODNR recommends a 300-foot buffer on W-3.
Worst case
The same rule on the worst case gives no rating above the point.
- Scenario
Final layout or HDD work affects W-3 or its 300-foot buffer, requiring Ohio EPA individual review and compensatory mitigation with a schedule effect of six months or more.

2What the record shows
The five inputs
Present: yes
Field delineation documents Sallow Creek, four tributaries and five wetlands including Category 3 wetland W-3 (C-8644116b06, C-a0386d398c, C-e5bfe1d5f5, C-3d096bbe0e). Upland cropland points without hydric indicators (C-cfe8567236) describe those points only and do not contradict the mapped features. Sallow Creek not being on the impaired list (C-846e2b0e13) concerns water quality, not presence.

Extent: core
Perennial Sallow Creek flows north to south through the middle of the Project Area for about 6,850 linear feet, with its floodplain, W-3 and riparian forest (C-8644116b06, C-29b335e462, C-e10af45ca9, C-3d096bbe0e). It bisects the site, so collection and access routes must cross it.
Cites C-8644116b06, C-29b335e462, C-e10af45ca9, C-3d096bbe0e
Avoidable: partly
The May 8, 2023 draft layout avoids all five wetlands with ODNR buffers (C-13ca79b38e), but crossings are not avoidable: two HDD collection crossings of Sallow Creek and an S-4 ephemeral access road culvert (C-67f16faf2c, C-336bf30d1a, C-441acfa155). Avoidance of W-3 depends on final design.
Cites C-13ca79b38e, C-67f16faf2c, C-336bf30d1a, C-441acfa155
Pathway: standard
The only planned fill is about 40 linear feet (0.02 acre) of ephemeral channel under NWP 14 without pre-construction notification; HDD crossings need no permit absent frac-out (C-336bf30d1a, C-67f16faf2c). Ohio EPA general 401 coverage would apply (OH-401). Individual review arises only if W-3 is affected (C-4a94b88b6a).
Cites C-336bf30d1a, C-67f16faf2c, C-4a94b88b6a, C-8b50a6949e
Impact likely: yes
A culvert crossing of S-4 is planned and Sallow Creek will be bored beneath. A haul-route culvert at S-2 also needs load rating (C-336bf30d1a, C-67f16faf2c, C-fe62671132). Some physical effect on waters is likely even with avoidance of wetlands.

- Applicability
- Conditional
- Instrument
- Clean Water Act Section 404 (33 U.S.C. 1344); 33 CFR Parts 320-332
- Trigger
- Fill or discharge in jurisdictional waters or wetlands (roads, crossings, grading).
- Description
Regulates discharge of dredged or fill material into waters of the United States, including wetlands. Permit type depends on the area of impact and the activity. NWP 51 (land-based renewable energy) allows the loss of up to 1/2 acre of non-tidal waters, with pre-construction notification above 1/10 acre.
- Typical timeline
NWP with a pre-construction notification: the permittee may presume the project qualifies unless the Corps responds within a 45-day period that starts on receipt of the notification (33 CFR 330.1(e)(1)); listed-species and historic-property clearances (see the Endangered Species Act and Section 106 rows) can hold authorization longer. Individual permit: decision target of 60 days after receipt of a complete application, subject to the exceptions in 33 CFR 325.2(d)(3). Typical: 2 to 4 months for an NWP with notification and 6 to 12 months or more for an individual permit (basis: practice, not stated in the sources).

Section 401 water quality certification (individual, or coverage under Ohio EPA's general certification of a Corps nationwide permit)
OH-401 · Ohio Environmental Protection Agency (Ohio EPA), Division of Surface Water (401 Water Quality Certification and Isolated Wetland Permitting Section)
- Applicability
- Conditional
- Instrument
- ORC 6111.03(O) and 6111.30; OAC Chapter 3745-32; Ohio EPA general 401 certification of the 2022 nationwide permits (2021-10-13)
- Trigger
- A federal license or permit (for example a Corps Section 404 permit) for an activity that may result in a discharge of dredged or fill material to a water of the state.
- Description
Anyone who needs a federal license or permit, such as a Corps Section 404 permit, for an activity that may discharge dredged or fill material to a water of the state must obtain a 401 certification from Ohio EPA before starting. No separate application is needed for a Corps nationwide permit that Ohio EPA has certified, if the project meets the certification's terms and conditions. Ohio EPA's certification of the 2022 nationwide permits carries conditions; for example, Category 3 wetland impacts above 0.1 acre need an individual certification, although Ohio EPA can grant coverage to a project that does not meet a condition (a director's authorization). For the 2021 nationwide permits, listed in the dated events, the Corps notice states that Ohio's certification was waived; confirm the treatment with the Corps district. An individual application must include current Corps correspondence on the jurisdictional status of the waters.
- Typical timeline
Individual certification: the application is due no later than 45 days after the Corps publishes its 404 public notice, and Ohio EPA acts within 180 days of a complete application. Nationwide permit with an Ohio EPA notification: work may proceed on Ohio EPA's written clearance, or once 45 calendar days have passed from Ohio EPA's receipt of the notification without a request for more information or an individual certification.
- As of the cut-off
As of the cut-off: The Corps' notice for the 16 nationwide permits that took effect on this date (NWPs 12, 21, 29, 39, 40, 42, 43, 44, 48, 50, 51, 52, 55, 56, 57 and 58, which include NWP 51 for land-based renewable energy and NWP 57 for electric utility lines) states that Ohio's Section 401 certification was waived for them. (2021-03-15) The 41 nationwide permits reissued for 2022 (including NWP 14, linear transportation projects) took effect with Ohio EPA's general Section 401 certification, issued with conditions on 2021-10-13; they expire 2026-03-14.

State isolated wetland permit for filling an isolated wetland (Level 1 general permit, or Level 2 or Level 3 individual permit)
OH-IWP · Ohio Environmental Protection Agency (Ohio EPA), Division of Surface Water
- Applicability
- Conditional
- Instrument
- ORC 6111.02 to 6111.028; OAC 3745-1-50 to 3745-1-54; Ohio EPA Level 1 isolated wetland general permit (effective 2022-07-21)
- Trigger
- Filling an isolated wetland, meaning a wetland that is not subject to regulation under the federal Water Pollution Control Act.
- Description
No one may fill an isolated wetland, meaning a wetland not subject to regulation under the federal Water Pollution Control Act, without an Ohio EPA isolated wetland permit. Review depends on wetland category and acreage. Level 1, a general permit: Category 1 or 2, one-half acre or less. Level 2, an individual permit: Category 1 over one-half acre, or Category 2 over one-half acre up to three acres. Level 3, an individual permit: Category 2 over three acres, or any Category 3. Ohio EPA lists review periods of 30, 90 and 180 days, public notice for Levels 2 and 3, and a mandatory hearing for Category 3. A Level 1 notice needs an ORAM 5.0 form for each wetland and a Corps determination that the wetlands are not waters of the United States; a preliminary jurisdictional determination treats all wetlands as federal.
- Typical timeline
Ohio EPA review periods: 30 days for a Level 1 general permit, 90 days for a Level 2 individual permit and 180 days for a Level 3 individual permit, as listed on Ohio EPA's program page.
- Version of the law on the cut-off
- As in force from 2023-05-17 (the library text)
- As of the cut-off
As of the cut-off: Ohio EPA's Level 1 isolated wetland general permit (Category 1 and 2 wetlands, one-half acre or less) took effect and runs to 2027-07-21; it was in force on the cut-off. (2022-07-21) Sackett v. EPA held that the Clean Water Act reaches an adjacent wetland only if it has a continuous surface connection to a relatively permanent water of the United States, so more wetlands can fall outside federal jurisdiction and count as isolated under ORC 6111.02. By 2023-07-20 the federal agencies' implementation page said they would interpret waters of the United States consistent with the decision. (2023-05-25)

6Basis and limits
This report is a desk review of the documents quoted above, as the engine read them for an information cut-off of 2023-08-01.
It is not a field survey and not a modelled study: this review made no site visit and ran no acoustic, hydraulic or other model. Where the record is silent, the report says what is missing; it does not fill the gap.
Every statement, figure and quote is the engine's record as written. The headings and connecting words are fixed text of this room, the same in every report.
