INTERSERVICE SUPPORT AGREEMENTS (ISSA)
A.
General.
1.
An ISSA is an agreement that provides for interservice support from a non-
Department of Transportation (DOT) Federal activity. Use of an ISSA allows
contracting for a service when in-house (within DOT) performance is not the most
cost-effective means of accomplishing requirements. Interagency agreements may
also be documented using a Military Interdepartmental Procurement Request (MIPR),
a Memorandum of Understanding (MOU) or a Memorandum of Agreement (MOA).
Agreements termed ISSAs and MIPRs are typically reimbursable agreements. A
typical format is DOT F-2300.1, Reimbursable Agreement. MOAs and MOUs
typically cover non-monetary arrangements or arrangements where there is authority
for support without reimbursement. Commandant Instruction 5216.18, Memoranda of
Understanding/Agreement, dated November 9, 1998, clarifies the differences between
MOU/MOA. This instruction uses ISSAs for all interservice agreements, regardless
of format. Inherently governmental functions are not subject to competition with the
private sector and may be obtained from DOT and non-DOT Federal activities.
2.
The provisions of the Federal Property and Administrative Services Act of 1949, the
Economy Act of 1932 and the Government Management Reform Act of 1944 are
general authorities on the use of ISSAs. These ISSAs may be issued between Federal
departments or agencies unless the needed product or service can be obtained more
economically through in-house or private sector sources. The Economy Act shall not
be used to circumvent the competition requirements prescribed in the FAR. There are
numerous specific statutory authorities for dealing with other agencies. See Chapter 7
of Title 14 of the United States Code and 14 USC, section 93.
