Reading

No CDBG activity that involves physical work can commit or spend money before its environmental review is finished, and the review process has to match the size of the project. 24 CFR Part 58 sets five levels of review, from projects too small to need much of anything, up to the kind of large development that needs a full impact statement. Getting the level wrong, or spending money before clearance, is one of the most common and most consequential mistakes a CDBG grantee makes.

The five levels of environmental review under 24 CFR Part 58 Five levels of increasing review depth: exempt, categorically excluded not subject to 58.5, categorically excluded subject to 58.5, environmental assessment, and environmental impact statement. Most single-family rehabilitation work sits at level three. No choice-limiting action, including any acquisition, construction, or contract commitment, may occur until the environmental review is complete and, where required, the Certifying Officer requests and HUD (or the State) approves release of funds. 1. Exempt Studies, admin costs, technical assistance, public services with no physical effect 2. Cat. Excluded, not subject to 58.5 Rental assistance, non-construction econ. dev. 3. Cat. Excluded, subject to 58.5 Most GCHS work sits here Single-family rehab, 1 to 4 units · Statutory Checklist required 4. Environmental Assessment Ends in a FONSI, or escalates to level 5 5. Environmental Impact Statement Rare; large projects, e.g. 2,500+ housing units No choice-limiting action before release of funds Acquisition, construction, or a binding contract before RROF can jeopardize funding entirely.
Five levels of environmental review, deepest at the bottom. Most GCHS single-family rehab work lands at level three, categorically excluded subject to 58.5, which still requires a written Statutory Checklist.

The five levels

  1. Exempt. Studies, administrative costs, technical assistance, and public services that have no physical effect. The grantee still has to document the exemption in writing, it does not happen automatically just because no review was performed, and the flood insurance, coastal barrier, and runway clear zone requirements of 58.6 still apply.
  2. Categorically excluded, not subject to 58.5. Rental assistance, supportive services, and economic development activities that do not involve construction. This level needs a written determination in the Environmental Review Record plus compliance with the flood insurance, coastal barrier, and runway clear zone requirements of 58.6, even though it is excluded from the fuller review.
  3. Categorically excluded, subject to 58.5. Physical projects that fit within defined conditions, for example rehabilitation of a building with one to four residential units (density not raised past four units, land use unchanged), or repair of an existing public facility or improvement, other than a building, with no more than a 20 percent change in size or capacity. This level requires completing a Statutory Checklist that walks through the specific federal laws 58.5 incorporates.
  4. Environmental Assessment. Everything that is neither exempt nor categorically excluded lands here. An Environmental Assessment ends in either a Finding of No Significant Impact, a FONSI, or a finding that the impact is significant, which then requires the next level up.
  5. Environmental Impact Statement. Reserved for large projects, for example sites intended for 2,500 or more housing units (58.37), or any project found in an assessment to have a potentially significant impact. This level is, in practice, very rare under the CDBG program.

Most GCHS single-family rehabilitation work will sit at level 3, categorically excluded subject to 58.5, because that is exactly the category rehabilitation of one-to-four unit residential buildings was written for. The Statutory Checklist at that level is not a formality to skip past. It is where flood plain, historic preservation, and other federal cross-cutting requirements actually get checked against the specific property.

Release of funds and the Certifying Officer

Before funds can be committed for an activity that needed an Environmental Assessment, or that is categorically excluded subject to 58.5 and has circumstances requiring compliance with a federal law listed in 58.5, a Request for Release of Funds has to be submitted along with a certification. If the Statutory Checklist shows no such circumstances, the activity converts to exempt under 58.34(a)(12) and needs no Request for Release of Funds. The certification is signed by the Certifying Officer, the official authorized to sign for the responsible entity, typically the chief elected official or another official designated by formal resolution. In the State CDBG program the State approves the release (TDA issues an Authority to Use Grant Funds in TxCDBG); in HUD-administered grants HUD does. Nothing covered by the request can be obligated until that approval.

Choice-limiting actions

This is the part of Part 58 that catches grantees off guard. Before environmental clearance is complete, neither a recipient nor anyone else in the development process, including nonprofits, for-profit developers, and contractors, may commit HUD funds to the activity, and none of them may commit non-HUD funds or begin the activity if it would have an adverse environmental impact or limit the choice of reasonable alternatives (58.22). The restriction reaches further than most people expect: typical examples are executing binding agreements, acquiring or leasing real property, demolition, excavation, rehabilitation, construction, relocating structures, and converting land to a different use.

The part worth reading twice: this restriction covers CDBG or non-CDBG funds. A grantee that spends its own money, or a homeowner's own money, on a choice-limiting action before clearance can disqualify the project from CDBG assistance (committing funds early is a listed ground for objecting to a Request for Release of Funds), even though no CDBG dollar was involved in the premature spending. The exceptions are exempt activities and categorical exclusions not subject to 58.5, which may start as soon as the determination is documented. A homeowner who gets excited and starts demolition work themselves before the environmental review clears the project has created a real problem, not a minor paperwork issue.

Notice and comment periods

Two of the five levels carry public notice requirements:

  • Categorically excluded subject to 58.5, where compliance with a federal law is required: publish a combined Notice of Intent to Request Release of Funds, an NOI/RROF, with a 7-day public comment period (10 days if mailed and posted instead of published), before submitting the Request for Release of Funds to HUD or the State.
  • Environmental Assessment: a combined FONSI and NOI/RROF notice is published with a 15-day public comment period (18 days if mailed and posted). Counting starts the day after publication, and the Request for Release of Funds goes in only after the period ends. HUD, or the State in TxCDBG, then allows a further 15-day objection period, counted from receipt of the request, before funds can actually move. A 30-day FONSI comment period applies when a project draws considerable controversy or is unique (58.46).

These periods stack. An Environmental Assessment project has to clear the 15-day comment period, then the 15-day objection period, before funds are released (the 15-day objection period follows the 7-day route too), which is a real scheduling consideration for a project timeline, not just a compliance detail.

What this means in practice for GCHS

The practical sequence on a typical GCHS single-family rehab project: first confirm the project fits the categorically excluded subject to 58.5 category, which single-family rehab usually does. Second, complete the Statutory Checklist rather than treating environmental review as a rubber stamp. Third, and this is the step that actually prevents problems, make sure the homeowner and any contractor involved understand that no work, demolition, site prep, ordering materials for installation, nothing physical, happens before clearance, and that this restriction applies even to work the homeowner might want to pay for themselves in order to get started sooner. The choice-limiting action rule does not care whose money moves first. It cares whether an alternative was foreclosed before the review was done.

Why this matters

The choice-limiting action rule is the one that ends projects. Signing a contract, starting acquisition, or beginning construction before the State (or HUD) approves the Request for Release of Funds can jeopardize CDBG funding for the whole activity, whenever the activity needs a Request for Release of Funds.

  2. Exempt status or categorical exclusion
  3. A Statutory Checklist or an NOI/RROF
  4. A Finding of No Significant Impact, a FONSI, or a finding of significant impact requiring the next level of review

5. At approximately what project size does an Environmental Impact Statement become necessary?

  1. Sites for 2,500 or more housing units, a level described as very rare under CDBG
  2. Any project exceeding $300,000 in total assistance, since larger grants always require an Environmental Impact Statement
  3. Any project involving more than 4 residential units, whether or not the work is a rehabilitation
  4. Any project requiring a Request for Release of Funds

6. Who signs the certification submitted with a Request for Release of Funds?

  1. Any staff member the subrecipient designates in writing to handle its compliance paperwork
  2. The Certifying Officer, typically the chief elected official or a designee
  3. The project's general contractor
  4. A HUD field office director

7. Before environmental clearance, what actions does the choice-limiting action restriction prohibit a recipient from taking?

  1. Only actions that involve spending CDBG funds directly
  2. Only demolition and excavation, but not signing contracts
  3. Committing or spending funds on anything that would preclude the selection of alternative choices, including binding agreements, property acquisition or leasing, demolition, excavation, rehabilitation, construction, relocating structures, or converting land use
  4. Only actions occurring on property the recipient does not yet own

8. A homeowner spends personal, non-CDBG money to begin demolition on their own property before the environmental review for a CDBG-assisted rehabilitation project has cleared. Does the choice-limiting action rule apply to this spending?

  1. Yes, the restriction covers CDBG or non-CDBG funds, so the homeowner's own spending can disqualify the project
  2. No, the restriction applies only to funds that the recipient itself controls, so a homeowner spending private money is outside the rule entirely
  3. No, homeowner-funded work is always outside the scope of Part 58 because private money is never federal assistance
  4. Yes, but only if the homeowner's spending exceeds $2,000, the same figure that triggers Davis-Bacon

9. For a categorically excluded, subject to 58.5 project where compliance with a federal law is required, what notice and comment period applies before the Request for Release of Funds is submitted to HUD or the State?

  1. A 30-day comment period, matching the Consolidated Plan
  2. A 15-day comment period, the period for a combined FONSI and NOI/RROF notice
  3. No public notice or comment period is required at this level of review
  4. A combined NOI/RROF notice with a 7-day public comment period

10. For an Environmental Assessment, what public comment period applies after the combined FONSI and NOI/RROF notice is published, and what happens after the Request for Release of Funds is submitted?

  1. At least 30 days must pass, and HUD then holds a further 7-day comment period
  2. A 15-day comment period must end first, and HUD or the State then holds a further 15-day objection period before funds are released
  3. No waiting period applies, but HUD holds a 30-day comment period after submission
  4. At least 7 days must pass, with no further HUD comment period afterward

11. What must a grantee do even for an activity that is exempt from environmental review under level 1?

  1. Nothing; exempt activities require no documentation of any kind
  2. Submit a Request for Release of Funds regardless of exempt status
  3. Document the exemption in writing
  4. Complete a full Statutory Checklist

12. What is required at the categorically excluded, not subject to 58.5 level, beyond the written determination?

  1. A check against flood, coastal barrier, and runway clear zone requirements
  2. A full Environmental Assessment ending in a Finding of No Significant Impact and a 15-day notice
  3. A 15-day public comment period on a combined FONSI and NOI/RROF notice
  4. Nothing further; the written determination alone is sufficient
