[Adopted]
A.
Statement of purpose. The purpose of this article
is to safeguard potable water supplies from potential contamination
by preventing backflow from a water user's system into the public
water system, recognizing that there are varying degrees of hazard
and applying the principle that the degrees of protection should be
commensurate with the degrees of hazard. It is the intent of the Village
of New Paltz to comply with the requirements of New York State Sanitary
Code, Part 5, Section 5-1.31 which mandates that the supplier of water
protect its water system in accordance with procedures acceptable
to the New York State Commissioner of Health and to that extent, the
terms, conditions and provisions of the New York State Sanitary Code,
Part 5, Section 5-1.31 and the Cross Connection Control Manual published
by the New York State Department of Health are incorporated in this
article by reference as if more fully stated.
B.
Responsibility of the Superintendent of Public Works,
Code Enforcement Officer and Building Inspector. The Superintendent
of Public Works or his designated agent shall inspect the plumbing
in every building or premises in the Village of New Paltz as frequently
as in his judgment may be necessary to ensure that such plumbing has
been installed in such a manner as to prevent the possibility of pollution
of the water supply of the Village by the plumbing. The Superintendent
of Public Works, Code Enforcement Officer or Building Inspector shall
notify in writing the owner or authorized agent of the owner of any
such building or premises, to correct within a reasonable time any
plumbing installed or existing contrary to or in violation of this
article and which, in his judgment, may tend to cause the pollution
of the Village water supply, or otherwise adversely affect the public
health.
C.
Inspection. The Superintendent of Public Works or
his designated agent shall have the right of entry into any building
during reasonable hours, for the purpose of making inspection of the
plumbing systems installed in such building or premises provided that
with respect to the inspection of any single-family dwelling, consent
to such inspection shall first be obtained from a person of suitable
age and discretion therein or in control thereof.
Unless specifically defined below, words or
phrases used in this article shall be interpreted so as to give them
the meaning they have in common usage and to give this article its
most reasonable application.

outlet terminates below the rim of a tank or vat and the tank or vat
has an overflow of diameter not less than given in Table 3.85, the
overflow pipe shall be provided with an airgap as close to the tank
as possible.
A.
Toxic or hazardous substances not under pressure.
At the service connection to any premises on which any material dangerous
to health or toxic substance in toxic concentration is not handled
under pressure but is otherwise handled in such manner as to constitute
a cross-connection, the Village water supply shall be protected by
an approved RPZ unless such cross-connection is abated to the satisfaction
of the Superintendent of Public Works and approved by the County Health
Officer.
B.
Nonhazardous substances. At the service connection
to any premises on which a substance that would be objectionable (but
not necessarily hazardous to health) if introduced into the Village
water supply is handled in such a manner as to constitute a cross-connection,
the Village water supply shall be protected by an approved double
check valve assembly.
C.
Sewage and storm drain treatment plants and pumping
stations. At the service connection to any sewage treatment plant
or sewage pumping station, the Village water supply shall be protected
by an airgap separation. The airgap shall be located as close as practicable
to the service connection and all piping between the service connection
and receiving tank shall be entirely visible. If these conditions
cannot be reasonably met, the Village water supply shall be protected
with an approved RPZ providing this alternative is acceptable to both
the Superintendent of Public Works and the County Health Officer.
A final decision in this matter shall be made by the State Health
Department.
