Subpart A—General: Federal Laws and Authorities
§ 50.1
Purpose, authority, and applicability.
(a) This part implements the policies of the National Environmental Policy Act (NEPA) and other environmental requirements (as specified in § 50.4).
(b) NEPA (42 U.S.C. 4321 et seq.), establishes national policy, goals and procedures for protecting, restoring and enhancing environmental quality. NEPA is implemented by Executive Order 11514 of March 5, 1970, (3 CFR, 1966-1970 Comp., p. 902) as amended by Executive Order 11991 of May 24, 1977, (3 CFR, 1977 Comp., p. 123) and by the Council on Environmental Quality (CEQ) Regulations, 40 CFR parts 1500-1508.
(c) The regulations issued by CEQ at 40 CFR parts 1500-1508 establish the basic procedural requirements for compliance with NEPA. These procedures are to be followed by all Federal agencies and are incorporated by reference into this part. This part, therefore, provides supplemental instructions to reflect the particular nature of HUD programs, and is to be used in tandem with 40 CFR parts 1500-1508 and regulations that implement authorities cited at § 50.4.
(d) These regulations apply to all HUD policy actions (as defined in § 50.16), and to all HUD project actions (see § 50.2(a)(2)). Also, they apply to projects and activities carried out by recipients subject to environmental policy and procedures of 24 CFR part 58, when the recipient that is regulated under 24 CFR part 58 claims the lack of legal capacity to assume the Secretary's environmental review responsibilities and the claim is approved by HUD or when HUD determines to conduct an environmental review itself in place of a nonrecipient responsible entity. For programs, activities or actions not specifically identified or when there are questions regarding the applicability of this part, the Assistant Secretary for Community Planning and Development shall be consulted.
§ 50.2
Terms and abbreviations.
(a) The definitions for most of the key terms or phrases contained in this part appear in 40 CFR part 1508 and in the authorities cited in § 50.4.
The following definitions also apply to this part:
Environmental review means a process for complying with NEPA (through an EA or EIS) and/or with the laws and authorities cited in § 50.4.
HUD approving official means the HUD official authorized to make the approval decision for any proposed policy or project subject to this part.
Project means an activity, or a group of integrally-related activities, undertaken directly by HUD or proposed for HUD assistance or insurance.
(b) The following abbreviations are used throughout this part:
AS/CPD—Assistant Secretary for Community Planning and Development.
CEQ—Council on Environmental Quality
EA—Environmental Assessment
EIS—Environmental Impact Statement
FONSI—Finding of No Significant Impact
HUD—Department of Housing and Urban Development
NEPA—National Environmental Policy Act
NOI/EIS—Notice of Intent to Prepare an Environmental Impact Statement
§ 50.3
Environmental policy.
(a) It is the policy of the Department to reject proposals which have significant adverse environmental impacts and to encourage the modification of projects in order to enhance environmental quality and minimize environmental harm.
(b) The HUD approving official shall consider environmental and other Departmental objectives in the decisionmaking process.
(c) When EA's or EIS's or reviews under § 50.4 reveal conditions or safeguards that should be implemented once a proposal is approved in order to protect and enhance environmental quality or minimize adverse environmental impacts, such conditions or safeguards must be included in agreements or other relevant documents.
(d) A systematic, interdisciplinary approach shall be used to assure the integrated use of the natural and social sciences and the environmental design arts in making decisions.
(e) Environmental impacts shall be evaluated on as comprehensive a scale as is practicable.
(f) HUD offices shall begin the environmental review process at the earliest possible time so that potential conflicts between program procedures and environmental requirements are identified at an early stage.

(h) For HUD grant programs in which the funding approval for an applicant's program must occur before the applicant's selection of properties, the application shall contain an assurance that the applicant agrees to assist HUD to comply with this part and that the applicant shall:
(1) Supply HUD with all available, relevant information necessary for HUD to perform for each property any environmental review required by this part;
(2) Carry out mitigating measures required by HUD or select alternate eligible property; and
(3) Not acquire, rehabilitate, convert, lease, repair or construct property, nor commit or expend HUD or local funds for these program activities with respect to any eligible property, until HUD approval of the property is received.
(i)(1) It is HUD policy that all property proposed for use in HUD programs be free of hazardous materials, contamination, toxic chemicals and gasses, and radioactive substances, where a hazard could affect the health and safety of occupants or conflict with the intended utilization of the property.
(2) HUD environmental review of multifamily and non-residential properties shall include evaluation of previous uses of the site and other evidence of contamination on or near the site, to assure that occupants of proposed sites are not adversely affected by the hazards listed in paragraph (i)(1) of this section.
(3) Particular attention should be given to any proposed site on or in the general proximity of such areas as dumps, landfills, industrial sites or other locations that contain hazardous wastes.

(b) Copies of environmental reviews and findings shall be maintained in the project file for projects, in the rules docket files for Federal Register publications, and in program files for non-Federal Register policy documents.

Subpart C—General Policy: Decision Points
§ 50.16
Decision points for policy actions.
Either an EA and FONSI or an EIS on all policy actions not meeting the criteria of § 50.19 shall be completed prior to the approval action. Policy actions include all proposed Federal Register policy documents and other policy-related Federal actions (40 CFR 1508.18). The decision as to whether a proposed policy action is categorically excluded from an EA shall be made by the Program Environmental Clearance Officer (PECO) in Headquarters as early as possible. Where the PECO has any doubt as to whether a proposed action qualifies for exclusion, the PECO shall request a determination by the AS/CPD. The EA and FONSI may be combined into a single document.
§ 50.17
Decision points for projects.
Either an EA and FONSI or an EIS for individual projects shall be completed before the applicable program decision points below for projects not meeting the criteria of § 50.20. Compliance with applicable authorities cited in § 50.4 shall be completed before the applicable program decision points below unless the project meets the criteria for exclusion under § 50.19.
(a) New Construction. (1) Project mortgage insurance or other financial assistance for multifamily housing projects (including sections 202 and 811), nursing homes, hospitals, group practice facilities and manufactured home parks: Issuance of Site Appraisal and Market Analysis (SAMA) Letter or initial equivalent indication of HUD approval of a specific site;
(2) Public Housing: HUD approval of the proposal.
(3) Loan Guarantee Recovery Fund Program (24 CFR part 573). HUD issuance of a letter of commitment or initial equivalent indication of HUD approval.
(b) Rehabilitation projects. Use the decision points under “new construction” for HUD programs cited in paragraph (a) of this section; otherwise the decision point is the HUD project approval.
(c) Public housing modernization programs. HUD approval of the modernization grants.
(d) Property Disposition. Multifamily structures, college housing, nursing homes, manufactured homes and parks, group practice facilities, vacant land and one to four family structures: HUD approval of the Disposition Program.

(19) Activities of the Government National Mortgage Association under Title III of the National Housing Act (12 U.S.C. 1716 et seq.).
(20) Activities under the Interstate Land Sales Full Disclosure Act (15 U.S.C. 1701 et seq.).
(21) Refinancing of HUD-insured mortgages that will not allow new construction or rehabilitation, nor result in any physical impacts or changes except for routine maintenance; however, compliance with § 50.4(b)(1) is required.
(22) Approval of the sale of a HUD-held mortgage.
(23) Approval of the foreclosure sale of a property with a HUD-held mortgage; however, appropriate restrictions will be imposed to protect historic properties.
(24) HUD guarantees under the Loan Guarantee Recovery Fund Program (24 CFR part 573) of loans that refinance existing loans and mortgages, where any new construction or rehabilitation financed by the existing loan or mortgage has been completed prior to the filing of an application under the program, and the refinancing will not allow further construction or rehabilitation, nor result in any physical impacts or changes except for routine maintenance; however, compliance with §§ 50.4 (b)(1) and (c)(1) and 51.303(a) is required.

(4) Approval of handbooks, notices and other documents that provide operating instructions and procedures in connection with activities under a Federal Register document that has previously been subject to a required environmental review.
(5) Approval of a Notice of Funding Availability (NOFA) that provides funding under, and does not alter any environmental requirements of, a regulation or program guideline that was previously published in the Federal Register, provided that
(i) The NOFA specifically refers to the environmental review provisions of the regulation or guideline; or
(ii) The regulation or guideline contains no environmental review provisions because it concerns only activities listed in paragraph (b) of this section.
(6) Statutorily required and/or discretionary establishment and review of interest rates, loan limits, building cost limits, prototype costs, fair market rent schedules, HUD-determined prevailing wage rates, income limits and exclusions with regard to eligibility for or calculation of HUD housing assistance or rental assistance, and similar rate and cost determinations and related external administrative or fiscal requirements or procedures which do not constitute a development decision that affects the physical condition of specific project areas or building sites.
[61 FR 50916, Sept. 27, 1996, as amended at 62 FR 15802, Apr. 2, 1997; 63 FR 48990, Sept. 11, 1998; 68 FR 56127, Sept. 29, 2003]
§ 50.20
Categorical exclusions subject to the Federal laws and authorities cited in § 50.4.
(a) The following actions, activities and programs are categorically excluded from the NEPA requirements of this part. They are not excluded from individual compliance requirements of other environmental statutes, Executive orders and HUD standards cited in § 50.4, where appropriate. Form HUD-4128 shall be used to document compliance.

Where another agency's EIS is referred to the HUD Field Office in whose jurisdiction the project is located, the Field Environmental Clearance Officer shall determine whether HUD has an interest in the EIS and, if so, will review and comment. Any EIS received from another Federal agency requesting comment on legislative proposals, regulations, or other policy documents shall be sent to the AS/CPD for comment, and the AS/CPD shall provide the General Counsel the opportunity for comment.

Subpart E—Environmental Assessments and Related Reviews
§ 50.31
The EA.
(a) Form HUD-4128—Environmental Assessment and Compliance Findings for the Related Laws—is the EA form to be used for analysis and documentation by HUD for projects and activities under subpart E. The Departmental Environmental Clearance Officer shall approve the issuance of equivalent formats, if Form HUD-4128 does not meet specific program needs.
(b) The program representative shall obtain interdisciplinary assistance from professional experts and other HUD staff as needed. Additional information may also be requested of the sponsor/applicant. HUD is responsible for assessing and documenting the extent of the environmental impact.
§ 50.32
Responsibility for environmental processing.
The program staff in the HUD office responsible for processing the project application or recommending a policy action is responsible for conducting the compliance finding, EA, or EIS. The collection of data and studies as part of the information contained in the environmental review may be done by an applicant or the applicant's contractor. The HUD program staff may use any information supplied by the applicant or contractor, provided HUD independently evaluates the information, will be responsible for its accuracy, supplements the information, if necessary, to conform to the requirements of this part, and prepares the environmental finding. Assessments for projects over 200 lots/dwelling units or beds shall be sent to the Field Environmental Clearance Officer (FECO) or, in the absence of a FECO, to the Program Environmental Clearance Officer in Headquarters for review and comment.
§ 50.33
Action resulting from the assessment.
(a) A proposal may be accepted without modifications if the EA indicates that the proposal will not significantly (see 40 CFR 1508.27) affect the quality of the human environment and a FONSI is prepared.
(b) A proposal may be accepted with modifications provided that:
(1) Changes have been made that would reduce adverse environmental impact to acceptable and insignificant levels; and
(2) An Environmental Management and Monitoring Program is developed in accordance with § 50.22 when it is deemed necessary by the HUD approving official.
(c) A proposal should be rejected if significant and unavoidable adverse environmental impacts would still exist after modifications have been made to the proposal and an EIS is not prepared.
(d) A proposal (if not rejected) shall require an EIS if the EA indicates that significant environmental impacts would result.
§ 50.34
Time delays for exceptional circumstances.
(a) Under the circumstances described in this section, the FONSI must be made available for public review for 30 calendar days before a final decision is made whether to prepare an EIS and before the HUD action is taken. The circumstances are:
(1) When the proposed action is, or is closely similar to, one which normally requires the preparation of an EIS pursuant to § 50.42(b) but it is determined, as a result of an EA or in the course of preparation of a draft EIS, that the proposed action will not have a significant impact on the human environment; or
(2) When the nature of the proposed action is without precedent and does not appear to require more than an assessment.
(b) In such cases, the FONSI must be concurred in by the AS/CPD and the Program Environmental Clearance Officer. Notice of the availability of the FONSI shall be given to the public in accordance with paragraphs (a) through (d) of § 50.23.
§ 50.35
Use of prior environmental assessments.
When other Federal, State, or local agencies have prepared an EA or other environmental analysis for a proposed HUD project, these documents should be requested and used to the extent possible. HUD must, however, conduct the environmental analysis and prepare the EA and be responsible for the required environmental finding.
§ 50.36
Updating of environmental reviews.
The environmental review must be re-evaluated and updated when the basis for the original environmental or compliance findings is affected by a major change requiring HUD approval in the nature, magnitude or extent of a project and the project is not yet complete. A change only in the amount of financing or mortgage insurance involved does not normally require the environmental review to be re-evaluated or updated.

§ 50.41
EIS policy.
EIS's will be prepared and considered in program determinations pursuant to the general environmental policy stated in § 50.3 and 40 CFR 1505.2 (b) and (c).
§ 50.42
Cases when an EIS is required.
(a) An EIS is required if the proposal is determined to have a significant impact on the human environment pursuant to subpart E.
(b) An EIS will normally be required if the proposal:
(1) Would provide a site or sites for hospitals or nursing homes containing a total of 2,500 or more beds; or
(2) Would remove, demolish, convert, or substantially rehabilitate 2,500 or more existing housing units (but not including rehabilitation projects categorically excluded under § 50.20), or which would result in the construction or installation of 2,500 or more housing units, or which would provide sites for 2,500 or more housing units.
(c) When the environmental concerns of one or more Federal authorities cited in § 50.4 will be affected by the proposal, the cumulative impact of all such effects should be assessed to determine whether an EIS is required. Where all of the affected authorities provide alternative procedures for resolution, those procedures should be used in lieu of an EIS.
§ 50.43
Emergencies.
In cases of national emergency and disasters or cases of imminent threat to health and safety or other emergency which require the taking of an action with significant environmental impact, the provisions of 40 CFR 1506.11 and of any applicable § 50.4 authorities which provide for emergencies shall apply.
