section 12521 of Act No. 368 of the Public Acts of 1978, as amended, being S

333.12521 of the Michigan Compiled Laws.

(3) "Escherichia coli" or "E. coli" means a bacteria which is a member of the

family enterobacteriaceae and which is the predominant facultative anaerobe in humans

and warm-blooded animals. Therefore, it is an indicator of the presence of human or

animal fecal material in water. The organism is identified by a variety of laboratory

methods with definitive identifying characteristics described by Bergey's Manual of

Bacteriology (Williams and Wilkins, 9th Edition, 1994).

(4) "Geometric mean" means the antilog of the summation of the logarithms

of the values for the samples examined divided by the number of samples.

(5) "Health officer" means the administrative officer of a city, county, or district

health department.

(6) "Sanitary or environmental survey" means and includes all of the following:

(a) A survey and an evaluation of data of the applicable contributory watershed for

pollution, including domestic, industrial, commercial, and agricultural sources.

(b) A survey and an evaluation of data of the bathing beach for sources of pollution

and safety hazards, including soil conditions, drop offs, water movement, and

submerged and other hazardous objects.

(c) Water depth in diving areas.

(d) An evaluation of proposed or existing bathing and swimming loads.

(7) "Standard methods" means the publication entitled Standard Methods for the

Examination of Water and Wastewater, 18th Edition - 1992, as published by the

American public health association, the American water works association, and the

water environment federation. This publication is adopted by reference in these rules and

is on file and available for inspection in the Bureau of Environmental and

Occupational Health, Michigan Department of Public Health, 3423 North Martin Luther

R 325.2102 Sanitation and safety determinations.

Rule 2. (1) Bacterial concentrations in water at a bathing beach, as determined by

standard methods, shall contain not more than 130 Escherichia coli (E. coli) per 100

milliliters, as a 30-day geometric

mean. Compliance shall be based on the geometric mean of all individual samples

taken during 5 or more sampling events representatively spread over a 30-day period.

Each sampling event shall consist of 3 or more samples taken at representative

locations within a designated sampling area. Bathing beach waters shall not contain

more than a maximum of 300 E. coli per 100 milliliters. Compliance shall be based on

the geometric mean of 3 or more samples taken during the same sampling event

at representative locations within a defined sampling area.

(2) Chemical determinations shall follow standard methods and shall show that the

water is free of chemical substances capable of creating toxic reactions or irritations to

the skin or membranes of a bather or swimmer.

(3) Physical determinations shall show the water to be free of all of the following:

(a) Turbidity.

(b) Color.

(c) Deposits.

(d) Growths.

(e) Oils.

(f) Greases.

(g) Any other substances in the water capable of creating a health or safety hazard

or a nuisance to a bather or swimmer.

Rule 3. (1) When, in the judgment of a health officer having jurisdiction, an

evaluation of information provided by sanitary survey and bacteriological, biologic,

chemical, or physical data provides evidence that a bathing beach may be detrimental to

the health or safety of the bathers or swimmers, it shall be determined to be unsafe.

(2) If voluntary closure of a bathing beach cannot be accomplished, the health

officer shall take action as provided by section 12541 of the act.
