[§340E-2]  Drinking water standards. 
(a)  The director shall promulgate and enforce State Primary Drinking Water
Regulations and may promulgate and enforce State Secondary Drinking Water
Regulations.  State Primary Drinking Water Regulations shall protect health to
the extent feasible, using technology, treatment techniques, and other means
which are generally available, taking cost into consideration.  Maximum
contaminant levels covered by revised National Primary Drinking Water
Regulations shall be set at a level at which no known or anticipated adverse
effects on the health of persons occur and which allows an adequate margin of
safety.  Treatment techniques covered by revised National Primary Drinking
Water Regulations shall require treatment necessary to prevent known or
anticipated adverse effects on the health of persons.  The State Primary
Drinking Water Regulations shall be not less stringent than the National
Primary Drinking Water Regulations in effect at that time.



(b)  Subject to section 340E-3, State Primary
and Secondary Drinking Water Regulations shall apply to each public water
system in the State; however, such regulations shall not apply to a public
water system which:



(1)  Consists only of distribution and storage
facilities (and which does not have any collection and treatment facilities);



(2)  Obtains all of its water from, but is not owned
or operated by, a public water system to which such regulations apply;



(3)  Does not sell water to any person; and



(4)  Is not a carrier which conveys passengers in
interstate commerce.



(c)  The director shall adopt and implement
procedures for the enforcement of State Primary Drinking Water Regulations,
including monitoring, inspection, and recordkeeping procedures, that comply
with regulations established by the administrator pursuant to the Federal Act.



(d)  The director may promulgate and enforce
regulations relating to cross-connection and backflow prevention control.



(e)  The director shall promulgate regulations
establishing an underground injection control program.  Such program shall
prohibit any underground injection which is not authorized by a permit issued
by the director, except that the director may authorize underground injection
by regulation.  Underground injection authorized by regulation shall not
endanger drinking water sources.  Any underground injection control program
shall:



(1)  Set standards and prohibitions controlling any
underground injection if such injection may result in the presence of any
contaminant in underground water which supplies or may be expected to supply
any public water system, and if the presence of such contaminant may result in
such system’s not complying with any national primary drinking water regulation
or may otherwise adversely affect the health of persons.



(2)  Require, in the case of a program which
authorizes underground injection by permit, that the applicant for the permit
satisfy the director that the underground injection will meet the requirements
of item (1) of this subsection.



(3)  Include inspection, monitoring, recordkeeping,
and reporting requirements. [L 1976, c 84, pt of §1; am L 1977, c 66, §1]
