agency, as defined in the Administrative Procedures Act, which has

an expenditure for postage of Two Thousand Dollars ($2,000.00) or

more for any one (1) fiscal year shall install a postage meter

machine and have all purchases of postage recorded on that postage

meter machine. Except, a field office or branch office of a state

agency distantly located from the parent agency, and which office

has an annual expenditure for postage of less than Two Thousand

Dollars ($2,000.00), may purchase postage stamps in the manner

prescribed by Section 90.2 of this title and such purchases shall

not be subject to the provisions of subsection B of this section.

B. Any agency, as defined in the Administrative Procedures Act,

not engaged in scientific research or community development, which

finds it necessary, in order to more efficiently and effectively

carry out certain programs or functions, is hereby authorized, upon

making application to the Director of the Office of Management and

Enterprise Services showing sufficient need and upon approval by

said Director, to purchase not more than Two Thousand Dollars

($2,000.00) worth of postage stamps during any one (1) fiscal year

in the manner prescribed by Section 90.2 of this title, with a

method of accountability for the use thereof to be maintained and

subject to audit. Any agency of the state engaged in scientific

research or community development, which finds it necessary, in

order to effectively carry out such research or development, is

hereby authorized, upon making application to the Director of the

Office of Management and Enterprise Services showing sufficient need

and upon approval by the Director, to purchase postage stamps in the

amount demonstrated necessary to pursue such research or development

in the manner prescribed by Section 90.2 of this title, with a

method of accountability for the use thereof to be maintained and

subject to audit. Provided, however, the finance officer of such

state agency shall keep and maintain a record of all postage stamp

allocations within the agency. For purposes of this section,

"scientific research" shall mean research conducted under formally

sponsored grants or contracts; "community development" shall mean

development conducted by a formally and permanently organized office

for that purpose.

codes, mailer applied bar codes or such other services offered by

the United States Postal Service for the purpose of reducing postal

costs and promoting efficiency. The Office of Management and

Enterprise Services shall oversee the implementation of the
