 system have been fully considered in developing such 

 project, and that the final decisions on the project 

 are made in the best overall public interest, taking 

 into consideration the need for fast, safe and effi- 

 cient transportation, public services, and the costs 

 of eliminating or minimizing such adverse effects

 plement the appropriate noise level standards. The 

 Secretary, after consultation with the Administra- 

 tor of the Environmental Protection Agency and 

 appropriate Federal, State, and local ofBcials, may 

 promulgate standards for the control of highway 

 noise levels for highways on any Federal-aid system 

 for which project approval has been secured prior to 

 July 1, 1972. The Secretary may approve any proj- 

 ect on a Federal-aid system to which noise-level 

 standards are made applicable under the preceding 

 sentence for the purpose of carrying out such stand- 

 ards. Such project may include, but is not limited to, 

 the acquisition of additional rights-of-way, the con- 

 struction of physical barriers, and landscaping.

 purposes of this title. 



(j) The Secretary, after consultation with the 

 Administrator of the Environmental Protection 

 Agency, shall develop and promulgate guidelines to
