been completed. At the time of transmitting the five year program to
the county governing bodies the Commission shall send them a
status report with respect to all projects approved by county govern-
ing bodies which have not been completed as of the date of the
transmitted program. The Commission shall identify the project,
give the date of approval or the dates of approval if it has been
approved on more than one occasion, and indicate the current
status thereof and an estimate of the date of completion of con-
struction, and indicate whether any material changes have been
made in the project since its last date of approval.]

[(f) Extension beyond approved area. The Sanitary Commis-
sion shall not extend or approve construction of sewer of any size or
capacity to serve properties in either Montgomery County or Prince
George's County beyond the area which has been approved for
major extension in a five year program until the county governing
body for the county involved has first approved such extension, nor
extend a water line of any size or capacity beyond the approved
terminal point of a five year project water line, except where such
extension would provide water to a development which is within
an approved sewer project area or with respect to which the county
governing body has approved the installation of individual sewage
disposal facilities, unless the county governing body has first ap-
proved such extension. Any extension requiring county governing
body approval under this subsection shall be submitted to the county
governing body in the usual form of communication between the
county governing body and the Commission, and unless within thirty
days after receipt of the Commission's material the county govern-
ing body advises the Commission that the extension should not be
made, the Commission may proceed with such construction.]

[(g) Amendments to the programs. Any material change from
a finally adopted five year program shall require an amendment to the
program before the project may be constructed. Normal deviations
from the last estimated construction costs, changes in location neces-
sitated by right of way acquisition problems or conditions found in
the field at the time if preparation of actual construction plans and
modification of estimated sizes or lengths of construction items shall
not be considered material changes so long as service from the
project as constructed is not provided, with respect to sewer projects,
beyond the area approved therefor. The program may be amended
by the next annual revision, or an interim amendment may be
accomplished by the following procedures. The Sanitary Commission
may propose an amendment to a five year program by a resolution
which shall before final adoption be transmitted along with a
statement of explanation to the Maryland-National Capital Park and
Planning Commission, and the same procedures followed with
respect thereto as
