NEWS ITEMS
April 17, 2008 - FHWA NEPA-RTP-TIP Guidance
FHWA circulated a memo (PDF file) in February 2008 that appears to change how projects must be listed in the RTP and TIP before environmental and preliminary engineering work starts. A prior (2003) FHWA memo also still applies (PDF file
).
FHWA noted in a March meeting (from CFPG meeting notes):
This issue pertains to Planning and the relationship to the information that needs to be in the FTIP. If the project is programmed in the TIP, but is not fully funded in the RTP, you must have at least an environmental process/study funded in the RTP. This actually allows more flexibility, especially for the earmarks. This allows you to get near the end of the environmental process before full funding for the project is required in the RTP. There must be an indication of the project in the Plan or some reference to the project if leading to NEPA document. This may have conformity implications if a project is in PE in the TIP and considered a study in the RTP – conformity will be required when additional funds are added in the RTP.
March 21, 2007 - EPA letter discussing effect of December 22, 2006 8-hour ozone court decision
From EPA:
Attached please find a 3/19/07 memo from William Wehrum, EPA's Acting Assistant Administrator for Air and Radiation. The memo discusses the impacts of the 12/22/06 decision by the DC Circuit Court of Appeals regarding EPA's Phase I Implementation Rule for 8-hour ozone. Although he recognizes that some requirements applicable to areas may change, Mr. Wehrum concludes that it is prudent for States to continue efforts to develop and submit 8-hour ozone plans expeditiously in order to protect public health.
We will keep you informed on further developments. In addition to the EPA headquarters contacts identified in the memo, you may direct questions to Dave Jesson (jesson.david@epa.gov, 415/972-3957) or John Kelly (kelly.johnj@epa.gov, 415/947-4151) of my staff.
