Prince George's County beyond the area which has been approved for
major extension in a five year program until the [County Council]
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
[Montgomery County] county governing body Health Depart-
ment has approved the installation of individual sewage disposal
facilities, unless the [County Council] county governing body has
first approved such extension. Any extension requiring [County
Council] county governing body approval under this subsection shall
be submitted to the [Council] county governing body in the usual
form of communication between the [Council] county governing
body and the Commission, and unless within thirty days after receipt
of the Commission's material the [County Council] county govern-
ing body advises [d] the Commission that the extension should not
be made, the Commission may proceed with such construction.

[(g)] (h) 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 devia-
tions from the last estimated construction costs, changes in location
necessitated by right of way acquisition problems or conditions found
in the field at the time of 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 accom-
hshed 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 specified in Subsection (b) (C), above, [provided,] and [if it in-
volves a water or sewer line in Montgomery County] by submission to
the [Montgomery County Council] pertinent county governing body,
with respect to which the procedures specified in Subsection [(c)]
(d), above, shall apply. EACH COUNTY GOVERNING BODY MAY
INITIATE AN AMENDMENT TO A FIVE YEAR PROGRAM,
INCLUDING THE ADDITION OF A NEW PROJECT OR THE
ACCELERATION OR MODIFICATION OF A PREVIOUSLY AP-
PROVED PROJECT, IN ACCORDANCE WITH THE FOLLOWING
PROCEDURES. THE COUNTY GOVERNING BODY SHALL AD-
VISE THE COMMISSION OF ITS DESIRES IN THAT CONNEC-

TION SPECIFIED IN SUBSECTION (B), ABOVE. AS SOON AS
MAY BE FEASIBLE, BUT IN ANY EVENT WITHIN 90 DAYS
AFTER RECEIPT OF THE COUNTY GOVERNING BODY'S AD-
VICE AND DIRECTION, THE COMMISSION SHALL SUBMIT
THE PROPOSED AMENDMENT, WITH ITS RESOLUTION
THEREON, TO THE COUNTY GOVERNING BODY WHICH
