water supply, sewerage or drainage systems provided for under this
sub-title, and it may construct in any such street, road, alley or public
highway, a water main, sewer or drain or any appurtenance thereof,
without the receipt of a permit or the payment of a charge; provided,
that whenever any State, County or municipal highway is to be dis-
turbed the public authority having control thereof shall be duly noti-
fied; and provided further, that said highway shall be repaired and
left by the Commission in the same condition as, or in a condition
not inferior to, that existing before said highway was torn up, and
that all costs incident thereto shall be borne by the Commission.

193. Any employee or agent of the Commission shall have the
right of entry, at all reasonable hours, upon any private premises
and into any building, in such sanitary district, while in pursuit of
his official duties, upon first presenting proper credentials from the
Commission, and any restraint or hindrance offered to such entry
by any owner or tenant, or agent of said owner or tenant, or any
other person, shall be a misdemeanor punishable under Section 21
of this sub-title.

191*. All individuals, firms or corporations having buildings, con-
duits, pipes, tracks, poles or other structures or obstructions in, on,
over, under or through any public road, street or alley of any sani-
tary district, or any portion of St. Mary's County outside of any
sanitary district, which shall block or impede the construction and
establishment of the Commission's water supply, sewerage or drain-
age systems, or other works, shall upon reasonable notice from the
Commission, promptly so shift, adjust, accommodate or remove such
structures or obstructions as to fully meet the exigencies occasioning
such action; provided, however, that the costs of such changes shall
be borne and paid for by the Commission. Every public service
corporation, company or individual before it or they shall begin any
excavation or construction in any street, road, alley or public high-
way within any sanitary district shall file with the Commission plans
of such work and construction showing the location and depth in
such street, road, alley or public highway, of the proposed main,
conduit, pole, pipe or other structure, and such construction or work
shall not be begun until said plan shall have been approved by the
Commission, nor shall any change be made in said approved plan or
in the work or construction as shown upon said except on further
approval of the Commission. Whenever any main, conduit, pole,
pipe or other structure is put in without the filing of plans with the
Commission and the approval thereof by it, or when any change
is made in the location of such main, conduit, pipe, pole or other
structure as shown upon the plans approved by the Commission, or
any approved change therein, the Commission may, if and when such
conduit, main, pipe or pole, or other structure, interferes with the
construction of or operation of its water or sewerage system, or other
works, remove such conduit, main, pipe, pole or other structures or
change the location thereof at the cost and expense of the party so
putting them in, or their heirs, assigns or successors, and without
any liability upon the part of the Commission for damage that might
be done to the same by reason of the Commission's operations in con-
structing or maintaining its systems or works. Any violation of the
provisions of this section shall be a misdemeanor punishable under
Section 21 of this sub-title.
