Section 574.510 - Environmental procedures and standards(a) Activities under this part are subject to HUD environmental regulations in part 58 of this title, except that HUD will perform an environmental review in accordance with part 50 of this title for any competitive grant for Fiscal Year 2000.(b) The recipient, its project partners and their contractors may not acquire, rehabilitate, convert, lease, repair, dispose of, demolish, or construct property for a project under this part, or commit or expend HUD or local funds for such eligible activities under this part, until the responsible entity (as defined in § 58.2 of this title) has completed the environmental review procedures required by part 58 and the environmental certification and RROF have been approved (or HUD has performed an environmental review and the recipient has received HUD approval of the property). HUD will not release grant funds if the recipient or any other party commits grant funds (i.e., incurs any costs or expenditures to be paid or reimbursed with such funds) before the recipient submits and HUD approves its RROF (where such submission is required).(c) For activities under a grant to a nonprofit entity that would generally be subject to review under part 58, HUD may make a finding in accordance with § 58.11(d) and may itself perform the environmental review under the provisions of part 50 of this title if the recipient nonprofit entity objects in writing to the responsible entity's performing the review under part 58. Irrespective of whether the responsible entity in accord with part 58 (or HUD in accord with part 50) performs the environmental review, the recipient shall supply all available, relevant information necessary for the responsible entity (or HUD, if applicable) to perform for each property any environmental review required by this part. The recipient also shall carry out mitigating measures required by the responsible entity (or HUD, if applicable) or select alternate eligible property.68 FR 56130, Sept. 29, 2003
