A -- ON-SITE TECHNICAL SUPPORT SERVICES FOR THE SUBSURFACE PROTE= CTION AND REMEDIATION DIVISION IN ADA, OKLAHOMA -- INTENT TO NEGOTIATE ON SOLE SOU= RCE BASIS FOR ADDITIONAL LOE UNDER CURRENT CONTRACT SOL 68-C-98-138 DUE 040300 POC Kathleen Roe, phone (513)487-2144, fax (513)487-2109 WEB: Office of Acquisition Management -- Cincinnati Contracts, http://www.epa.gov/oam/cinn_cmd. E-MAIL: U.S. EPA -- Cincinnati Contracts Management Division, roe.kathleen@epa.gov. The U.S. Environmental Protection Agency (EPA) intends to negotia= te on a sole source basis with ManTech Environmental Services Research Corporat= ion for additional LOE of 9400 hours under Contract 68-C-99-138 for On-Site Tec= hnical Research Support Services for the Subsurface Protection and Remediation= Division (SPRD) in Ada, Oklahoma. In accordance with the authority of FAR 6.302= -1 as cited in 41 U.S.C. 253(c)(1), only one responsible source and no other = supplies or services will satisfy agency requirements. Specific services includ= e the following: analytical support; field technical support; ground water ch= emistry research support; biotransformations research support; ecosystem restor= ation protection research support and scientific data processing and informat= ion management support. Although other contractors may be able to perform = the required services, only the current contractor can perform the services= without unacceptable delays in fulfilling the Agency?s requirements and substan= tial duplication of cost to the Government that would not be recovered throu= gh competition. The Government expects to execute a sole source modificat= ion to the current contract for an additional 9400 hours of effort through 9/= 30/00. The additional LOE provided under this action will re-secure SPRD?s abi= lity to support Congressionally mandated programs. Failure to take this action = would result in negative consequences for EPA which include: (1) delayed com= pletion or interruption of on-going technical support currently being performed= under the contract; support which is relied upon by many offices within the A= gency; (2) increased risk of human exposure to contaminants due to delayed de= cisions which effect clean-up and restoration activities impacting human health= and the environment; (3) lost time and increased costs associated with the addi= tional effort required a for new contractor to gain an equal level of familiar= ity as that of the current contractor. A new contractor would lackManTech?s = acquired knowledge, experience and familiarity with the contract requirements, a= nd would be unable to provide continuity of work already begun under current wor= k assignments. However, any party that feels it is capable of meeting EP= A?s requirements may provide for consideration documentation which demonstr= ates that it can assume the incumbent?s role and perform the statement of work requirements. This notice of intent is not a request for competitive p= roposals. However, any proposal received within fifteen days after the electronic= publication date of this synopsis will be considered by the Government.= A determination by the Government not to compete this proposed contract modification based upon responses to this notice is solely within the d= iscretion of the Government. Information received will normally be considered sol= ely for the purpose of determining whether to conduct a competitive procurement= . This action is being processed under FAR Part 15, Contracting by Negotiation= . Posted 03/17/00 (D-SN435517). (0077)
