Guam § 53104 - Drinking Water Standards.

§ 53104. Drinking Water Standards.

(a) Guam EPA shall promulgate and enforce primary and

secondary drinking water regulations to protect health using

technology, treatment techniques, and other means which are

generally available.

(b) Primary and secondary drinking water regulations

promulgated pursuant to this Chapter shall be no less stringent

than the National Primary Drinking Water Regulations and

National Secondary Drinking Water Regulations in effect at that

time.

(c) Primary and secondary drinking water regulations

promulgated pursuant to this Chapter shall apply to each public

water system in Guam, including those owned and operated by

the government of Guam or federal agencies, unless it is a

system:

(1) which consists only of distribution and storage

facilities and does not have any collection and treatment

facilities;

(2) which obtains all of its water from, but is not

owned or operated by, a public water system to which such

regulations apply;

(3) which does not sell water to any person; and

(4) which is not a carrier which conveys passengers in

interstate commerce.

(d) Guam EPA shall adopt and implement procedures for

the enforcement of primary and secondary drinking water

regulations, including monitoring, inspection, and recordkeeping

procedures which are no less stringent than the Federal Act.

(e) Guam EPA shall promulgate and enforce regulations

relating to cross-connection control and backflow prevention.

The regulations shall establish minimum criteria that must be

met by all public water systems for the purpose of cross

connection control and backflow prevention, and shall allow for

the direct implementation by public water systems of cross

connection control and backflow prevention programs that meet

COL6/24/2021

the established criteria. Direct implementation of a cross

connection control and backflow prevention program by a public

water system shall not prevent Guam EPA from enforcing its

regulations against a public water system or any person.

(f) Guam EPA 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 Guam EPA except that Guam EPA 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 not complying with any national primary

drinking water regulations 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 Guam EPA Administrator that the

underground injection will meet the requirements of

Subsection (f)(1) of this Section;

(3) conform to all requirements of the Federal Act and

any applicable regulations promulgated thereunder; and

(4) include inspection, monitoring, recordkeeping,

and reporting requirements.

(g) Following the date on which the USEPA determines

that a primary drinking water regulation is to take effect, the

Guam EPA may allow up to two (2) additional years to comply

with a maximum contaminant level or treatment technique if the

Guam EPA (in the case of an individual system) determines that

additional time is necessary for capital improvements.
