County which are not within the Sanitary District or in a Rural

Water Area, and with respect to those portions of Prince George's

County not within the Sanitary District, the Commission's Plumbing
Rules and Regulations shall apply to the installation of any plumbing
commenced on or after June 1, 1965, but those rules and regulations
shall not apply to plumbing installations in existence on that date and
the owner of the property wherein the existing plumbing is located
shall not be required to change the existing plumbing until either
water or sewer service is obtained from a Commission system or the
existing plumbing is renovated, changed or replaced for any reason,
and upon the happening of any of those events the provisions of this
section and of the Commission's rules and regulations shall apply to
such property and such plumbing the same as if the property was
within the Sanitary District. Further, the Commission is authorized
to enter into an agreement with Prince George's County and Mont-

gomery County, or either of them, under which the County or Coun-

ties, as the case may be, will issue the necessary permit and perform
the necessary inspection for and in the name of the Commission in
those areas which are not within the Sanitary District, so long as such
agreement provides that the Commission's Plumbing Rules and
Regulations will be applied. Neither the immediately aforegoing
provision, nor any agreement entered into thereunder, shall derogate
from the Commission's power and authority to make and enforce
such rules and regulations as to the installation of plumbing in the
two Counties COUNTY as it may deem necessary for the public
health, nor shall it affect the Commission's authority and power with
respect to public and semi-public water supply and sanitary sewer-
age systems specified in Sections 83-77 and 83-78 (73-61) of this
subtitle. Any violation of any of the provisions of this section shall
be a misdemeanor punishable under Section 83-108 (73-89) of this
subtitle.

Sec. 2. And be it further enacted, That if any word, phrase, clause,
sentence or any part or parts of this Act shall be held unconstitutional
by any Court of competent jurisdiction, such unconstitutionally
shall not affect the validity of the remaining parts of this Act.

Sec. 3. And be it further enacted, That this Act shall take effect
June 1, 1965.

Approved May 4, 1965.
